Timóleon.Manufacturers, designers and suppliers of energy efficient heating and ventilation systems.

Our Name (tim-oh-leon)

Timóleon is the name of a Greek statesman and general who secured the island of Sicily from the Carthaginians in 340BC.

Sicily is dominated by Mt Etna, Europe’s largest active volcano and archaeological evidence indicates that when Timóleon began the process of reconstruction, the Greeks realised that if they erected buildings on ground below which there were magma flows of energy from Mt Etna, these buildings would always be warm and dry.

Timóleon and his team understood the principles of underfloor heating 300 years before the Romans introduced the hypocaust.

Today Timóleon continues to pioneer innovative heating technologies.

Considered the most comfortable and energy efficient method of heating. Timóleon has a product for every floor type, all designed and tested to work with renewable technologies.

Controls are essential in creating a comfortable living environment. Aura brings together the heating, ventilation and hot water in a single simple-to-use system.

Whole house ventilation provides a controlled supply of fresh air to bedrooms and living areas and removes stale, damp air from bathrooms and kitchens. The system uses a Heat Recovery Unit to collect and re-use the energy that would otherwise be lost.

Solar thermal energy can be used in the heating system, not just for hot water. Our unique system, using Timóleon’s range of low temperature underfloor heating, enables a significant proportion of the heating demand to come from solar energy.

We have a range of services available from SAP and Code for Sustainable Homes assessment to servicing and commissioning of the underfloor heating or ventilation system.

Combining heating and ventilation technologies together to improve the indoor environment whilst also reducing energy costs.

Total Indoor Environment is a concept that is at the core of the Timóleon philosophy – ensuring that the complementary technologies we bring together work effectively to achieve lower costs, both environmental and financial, whilst giving the user the comfort they want when they want.

Any particular technology does not stand alone but is affected and influenced by other devices used in the system. A holistic view of the system is needed to ensure that the benefits of using low carbon technologies are realised.

These technologies must be properly controlled with the ability for the individual to easily alter the comfort conditions to suit. Too often controls are independent, complicated and unintuitive which creates inefficient heating systems that are too hot, too cold or on for too long.

About the Total Indoor Environment

Why is this important?

Timóleon has an independent energy consultancy service, Tonos. Tonos is able to provide SAP and Code for Sustainable Homes assessment as well as Renewable Energy feasibility reports and MCS compliant heat loss calculations.

Using a whole house ventilation system with heat recovery not

only improves air quality but pre-heats the incoming air using

energy from the extract that would have been otherwise lost. Comfort conditions are

improved especially when combined with a radiant

underfloor heating system.

Fundamental to any efficient system are good controls. The Aura control system brings together the controls for the heating, domestic hot water and ventilation making the home’s controls easier to install and simpler to use.

Underfloor Heating

Solar energy can be used for heating. Usually the water collected in spring, autumn and winter is too cool to be used by radiators but using a Timóleon underfloor heating system with intelligent control and storage can double the useful contribution from solar thermal compared to a conventional twin coil cylinder or thermal store.

Comfortable room conditions can be achieved by using

underfloor heating. Timóleon underfloor heating products

work well with low water temperatures increasing the efficiency of the heat source

and facilitating the use of solar heating.

TIE creates the perfect indoor environment.

Solar thermal, controls & UFH

UFH & MVHR

A radiant heating system is acknowledged as being the most comfortable form of heating however by its nature a radiant system will take longer to warm the air when there are large draughts or high air changes, high incoming volumes of uncontrolled cold air can quickly reduce comfort levels.

This makes MVHR the perfect partner for UFH as it ensures that air coming into the building is “pre-warmed”. The two technologies complement each other to create better overall comfort conditions.

Energy collected using solar thermal can be used for the heating system. However, if the heating system is designed to operate at high water temperatures (as most conventional systems are) then it is difficult to make full use of the energy collected by the solar panels on, for example, a cloudy autumn day. This is because the temperature the energy is collected at is much lower than that needed by the heating system making it necessary to use a boiler to increase the water temperature.

A high performance emitter and renewable energy source can only be effective with good controls. The system must understand when to run the boiler or heat pump and when to use renewables such as solar thermal.

Many people want underfloor heating simply because it is the most comfortable form of heating, completely unobtrusive, safer and more hygienic than other forms of heating.

We understand this and part of our mission is to ensure that we supply the easiest and quickest to install, best-value underfloor heating, to suit every form of floor construction used in the UK including all forms of timber floor, and for room-by-room refurbishment projects as well as new-build.

But we go much further.

Our underfloor heating products have also been designed (and extensively tested) to absolutely minimise the amount of energy a building’s heating system requires in order to provide effective heating, and to make it realistic for this energy to come from renewable sources either straight away or at some stage in the future life of the building.

Two crucial aspects to the design of our products make this possible. The first is our products minimise the temperature of the heating system water required in order to provide effective heating. The lower this water temperature can be, the more efficiently a boiler can run and the more likely it is that water at this temperature can come from a truly renewable source.

Timóleon underfloor products are designed to be energy efficient, have high heat output and fast warm-up time.

Radiator heating systems and even some poorer forms of underfloor heating must be supplied with high-temperature (55-85˚C) water. This makes such buildings dependent on having a gas or oil boiler because a boiler is the only reliable way of producing water this hot.

All our underfloor heating products are effective using much cooler water (32-55˚C) which not only enables a gas or oil boiler to run much more efficiently but also maximises utilisation of water heated by renewable energy.

The second is the speed with which our products respond to changes in heating power demand. High thermal mass, pipe-in-screed underfloor heating cannot respond quickly to demand-changes, and can waste energy as a result.

Timóleon products have been designed with low thermal mass and this enables them to respond very quickly and efficiently to changes in heating demand.

Are All Underfloor Heating Systems The Same?

The emitter consists of pipe set within either a screed or timber floor. It should provide effective heating when covered with commonly-used floor finishes, while using low water temperatures. It should be designed to be effective at transferring energy between the pipe and the floor surface.

Good controls are essential for any heating system. Room temperatures should remain comfortable and the heating system should only be on when needed. Underfloor heating systems do not use thermostatic radiator valves so all temperature control is done by thermostats situated within each room. Using thermostats improves efficiency and comfort conditions.

The manifold distributes water from the primary heating system into the individual underfloor heating circuits. For ease of installation the manifold is best positioned in a central location. Manifolds may be fitted with a water mixing valve and secondary circulator wherever high temperature primary water needs to be reduced to the low water temperature needed by an underfloor heating system.

This supplies the warm water needed. It could be a boiler or any of the renewable energy alternatives. The higher the water temperature required by the emitter, the lower its efficiency will be.

Underfloor heating works by circulating warm water through pipe embedded within the floor construction. Heat from the pipe is transferred into the floor and then into the room providing enough warmth to heat the building all year round. This removes the need for radiators making more effective use of the space as well as eliminating any high temperature surfaces - an underfloor heating system generally has a surface temperature between 25°C and 27°C, lower than the palm of your hand. A conventional radiator can be as hot as 75˚C.

How does an underfloor heating system work?

The way in which underfloor heating transfers heat is also different to a radiator. Radiators transfer energy principally by convection, heating the air above and around the radiator causing the air to rise. As the warmed air is more buoyant than the cooler air in the room it will rise to the ceiling. The warmed air, as it crosses the ceiling, will begin to cool and then fall. This motion creates a convective current with higher air temperatures nearer the ceiling than the floor.

An underfloor heating system predominantly transfers radiant energy. Compared to radiators, a room with underfloor heating will have a higher radiant temperature with less temperature stratification, draughts and dust movements. This is why underfloor heating is considered the most comfortable form of heating.

Our systems are designed to work with the latest renewable energy technologies.

It is important that any heating system should be designed with the future in mind. If you install a heating system that depends on high water temperatures it is impractical to change in the future to a heat source such as a heat pump or solar cylinder which provides water at low temperatures.

Every heating system should now be designed to enable the homeowner to retrofit renewable technologies in the future. This means designing the system for the lowest possible water temperature.

Designed to be future proof.

BSRIA tests verify you can reduce your energy use with our underfloor heating systems.

At Timóleon we can draw on years of experience to deliver systems for the most challenging of installations. We know that the design and implementation of the underfloor heating is key to an efficient, energy saving and reliable system. We design all of our systems to deliver the best possible performance no matter what type of construction or building.

Our products are independently tested at BSRIA for heat output. This enables us to accurately compare the output of the underfloor heating system with the heat losses of the building to ensure that the system will work as specified.

With any heating system the larger the area of the emitter the cooler the surface temperature needs to be to achieve the same heating effect. This is why underfloor heating runs at a much lower water temperature compared to radiator systems. The use of lower water temperatures better utilises the condensing mode in boilers and allows heat pumps to have a greater efficiency. Studies have demonstrated that using underfloor heating rather than radiators with a ground source heat pump can make the heating system up to 30% more efficient.

Timóleon systems have been independently tested for performance.

The water temperature stated is that needed to provide the same heat output from each system.

Consumption based on a new build 4 bedroom 200m2 property using a ground source heat pump and heating system as shown.

Our products are perfectly suited to using heat pumps and other renewable energy sources. To be able to work with these technologies a heating system must be able to run at low water temperatures yet still provide sufficient heating to warm the building particularly in timber floors. This is important because a heat pump producing lower temperature water will reduce running costs and carbon emissions.

To ensure good performance at low water temperatures it is crucial that there is a conductive pathway that transfers heat quickly from the pipe to the floor surface. If there is a break in the conductive pathway i.e. an air gap, then the efficiency of this energy transfer is greatly reduced. To overcome this inefficiency the water used in the heating system needs to be much hotter to produce an effective heat output.

Independent tests at BSRIA showed that systems that have an air gap between the pipe and floor deck are less efficient at transferring energy than Timóleon systems. This means they have to use significantly warmer water to produce the same heat output.

SAP, used to determine the energy rating for Building Regulations, recognises that underfloor heating is energy efficient.

Using underfloor heating with a heat pump improves the SAP rating when compared to using a heat pump with radiators. If underfloor heating is installed within a timber “dry” floor the rating is improved even further as it has a faster warm-up time than an in-screed underfloor heating system.

We always strive to meet individual customer’s needs which is why when standard products don’t dovetail with customer’s requirements we're able to provide bespoke solutions.

We can design and manufacture products to suit the building construction, taking into consideration any acoustic details, loading requirements, services and floor fixtures.

We make sure our systems work well in every construction, including timber floors.

We draw on years of experience to develop and manufacture systems that are easily installed into timber constructions such as suspended, batten or floating floors.

However getting underfloor heating to work effectively in timber floors is not straightforward. Timber is not naturally a good conductor of heat. This means, for certain types of underfloor heating, using high temperature water is the only way the system will be able to heat the room effectively and as a result the efficiency of the heat pump or boiler will be reduced.

We are specialists in manufacturing UFH products for timber floors and have developed a range that works well at low water temperatures. Our systems are also designed to avoid squeaks and ticking and to maintain or improve the strength and acoustic qualities of the floor.

The calculations were based on a new build 100m2 timber frame house using a heat pump.

The BRE green guide is used to rate the construction dependent on the embodied energy of the materials used. This score is used in Code for Sustainable Homes assessments (domestic) and BREEAM (commercial). Below are examples of the ratings given to constructions in which Timóleon underfloor heating products are used. The Global warming Potential (GWP) of the insulation is based on a scale which promotes insulation having a GWPless than 5.

Code for Sustainable Homes (CFSH) and Timóleon UFH products

MIS3005 provides guidance for calculating the efficiency of the heating system. There are several options for the type of emitter used with the heat source which in turn determines the efficiency of the system. For example, using a screed underfloor heating system with a heat output of 50-80 W/m2 and a flow water temperature of 35˚C provided by a ground source heat pump scores the maximum 6 star rating. By comparison a radiator system using a flow water of 45˚C with a ground source heat pump scores only 4 stars as the higher flow temperature reduces the heat pump efficiency.

UFH and Micro-generation Certification Scheme (MCS) Calculations

*These products can be used in a timber construction increasing the CFSH credits awarded.

All Timóleon insulation based products have a GWP of less than 5 and will achieve the maximum credits for CFSH and BREEAM scoring for the construction element (pollution sections). Timóleon is able to provide full CFSH assessment through its Energy Consultancy service, Tonos.

A batten floor is a conventional way of installing a timber floor over a solid subfloor. This type of construction is frequently used in concrete and suspended separating floors to reduce the transfer of sound. The underfloor heating system within the batten space must be in contact with the floor deck to provide good thermal performance.

A floating floor consists of a floor deck supported on a continuous layer, usually insulation, that is not fixed directly to the subfloor. With any floating floor it is important to use insulation that has the appropriate compressive strength for the intended floor loads.

The use of underfloor heating in screeds is common place. Consideration should be given to moisture content and drying times. It is important that the underfloor heating system is not used to dry the screed.

A raised access floor is used to create a space under the floor so that other services can be easily routed through the building. With this type of construction the underfloor heating must be in direct contact with the raised floor to ensure good performance.

The manifold distributes hot water from the boiler or heat pump into each underfloor heating circuit. The pipe used in the underfloor heating circuit must be resilient, durable and easy to install.

In a separating floor there is a requirement to use a construction that reduces the transfer of sound. There are standard constructions referred to as Robust Details which, when followed exactly, ensure compliance with Part E of the Building Regulations. Our underfloor heating systems can be used as part of Robust Detail constructions.

Timber suspended floors use joists to support the floor deck. The underfloor heating system can either sit between the joists or within the floor deck itself. If an acoustic treatment is laid over the suspended floor then an underfloor heating system for a batten or floating floor should be used.

12mm PE-RT PIPE

ToronFloor panels are manufactured from flooring grade chipboard or plywood. The pre-machined panels are routed with a unique pattern to accept 12mm pipe. The design of the panel makes it suitable as a structural floor deck.

The panels are laid and fixed onto the joists in the same way as a normal chipboard floor. The pipe is installed into the grooves with the ends of the circuit dropping into the joist space to then continue to the manifold. Once the foil diffuser is fitted a standard overboard layer, such as 6mm ply, is fully glued on top to complete the floor.

As the pipe is embedded within the surface of the floor deck there is an excellent transfer of heat. This provides a high output even at low water temperatures making the system ideal for use with heat pumps and other renewable energy sources.

The ToronFloor heating system has been independently tested at TRADA for structural performance.

FoilBoard Suspended is an insulated underfloor heating panel installed between the joists of a suspended floor. To hold the panels in place brackets (or battens) are installed within the joist space to ensure that the system is in direct contact with the floor deck. This ensures an excellent transfer of heat from pipe to the deck.

The panels are manufactured from XPS insulation with a pre-bonded soft temper aluminium heat diffuser, making the panel easy to trim on site. Once brackets or support battens are installed the panels drop into place in exactly the right position.

FoilBoard suspended is available in 50mm & 75mm thicknesses. It is also available in FSC approved recyclable wood fibre board and has good thermal, acoustic and fire retardant properties.

A batten floor is a conventional way of installing a timber floor over a solid subfloor or when the ultimate floor deck is to be hardwood planks which must be fixed using nails or screws. This type of construction is frequently used in concrete and suspended separating floors to reduce the transfer of sound. Any underfloor heating system within the batten space must be in firm contact with the underside of the floor deck to provide good thermal transfer.

Timóleon underfloor heating systems are ideally suited for incorporation into acoustic constructions, both in residential and commercial applications. Part E of the Building Regulations shows how such constructions must provide resistance to the passage of sound. Compliance with the performance standards is demonstrated by passing a pre-completion test (PCT) for each individual construction. However PCTs can be avoided if a Robust Standard Detail (RSD) is adopted. Specific RSDs have been established for each construction and underfloor heating can be incorporated into an RSD construction provided:

Ì That no fixings or staples penetrate or break the separating resilient layer used in a construction.

Ì In a floating floor treatment the underfloor heating does not connect the structural floor with any of the floating floor elements thereby bridging the resilient layer.

There are a variety of RSD constructions and it is important to understand how effective the underfloor heating system will be when used with these constructions. In our guide to underfloor heating and acoustic constructions (TX 100) we show how underfloor heating can be simply incorporated.

Acoustic constructions are commonly found in residential buildings with floors, walls and ceilings that separate living spaces. These constructions are required to provide resistance to the passage of sound allowing occupants to enjoy quiet living conditions without being disturbed by those living in adjacent properties. Such buildings can benefit enormously from underfloor heating, not only to enhance the living environment but also to improve energy efficiency.

Our acoustic range of products are ideally suited for both residential & commercial applications.

The AB plate is installed directly over the acoustic battens. The product is designed to allow the installer to walk between plates. The AB plates have a pre-bonded insulation layer which improves the thermal transfer into the floor deck.

The FoilBoard ECO system is manufactured from wood fibre insulation and as such improves the acoustic performance of the floor compared to polystyrene insulation. The FoilBoard ECO is used as a floating floor with a Screed Replacement Board laid over.

The ClipPlate system does not require any fixings or staples. This ensures the acoustic layer isn’t punctured when the pipe is being laid. The ClipPlate product also comes with integrated insulation improving the thermal performance.

Batten systems with a resilient layer can be used in timber and concrete suspended floors. These are termed as floating floor treatments. The batten moves up and down due to the resilient layer so it is important the underfloor heating system moves with the batten to maintain contact with the floor deck.

E-FT-5 and E-FT-6 are Robust Detail constructions for floating floors in which underfloor heating can be installed. Floating Floor Treatments FFT4 and FFT5 cannot have underfloor heating installed within the resilient layer.

Underfloor heating systems used within a screed floor must not penetrate the resilient layer (i.e. using fixings such as staples) and must avoid bridging the screed to the slab.

Cool water can be used in the underfloor heating system to provide room cooling as an alternative to air-conditioning. It is also possible to chill the ceiling or wall to get the same effect. This method of cooling is called Surface Cooling.

Surface cooling

Surface cooling is able to provide comfort cooling to most commercial applications with outputs up to 70W/m2 for a ceiling system and 50W/m2 for a floor system. A surface cooling system will reduce the sensible loads in a space. It may be necessary, in humid conditions, to provide dehumidification. Dehumidifying a space also has the benefit of reducing the dew point (which limits surface temperature and therefore output) and increasing the cooling capability of the system.

Chilled water is provided by either a ground source or air source heat pump. A surface cooling system requires water at a higher temperature than that needed by an air conditioning system. This increases the efficiency of the air source heat pump. Where ground loops are installed the benefits are even greater. During the summer the ground temperature will be around 15°C at a depth of 2 metres. When coupled with a heat exchanger this chilled water can be used directly in the surface cooling system, making it almost free to run, with the benefit of recharging the ground, storing the unwanted heat energy until needed by the heat pump.

Air conditioning is responsible for 10% of the energy used in commercial buildings. Using surface cooling can significantly reduce energy consumption whilst provide a comfortable working environment.

The transfer of energy in a surface cooling system is mostly done by radiant heat exchange, approximately 80%. The absorbing surface, a floor, wall or ceiling is cooled to a temperature lower than the items and occupants within a room. This cooled surface will then absorb energy from within the room. In reducing the radiant temperature the occupants feel more comfortable even though the air temperature has only slightly changed. This effect is analogous to a church or cave where the walls and floor are at a lower temperature than the air making the space feel cooler. Air conditioning works in a different way, mechanically forcing air over cooling elements thereby cooling the air in the room but not significantly reducing the radiant temperature. This results in extremes of radiant and air temperature being created. Big differences between air and radiant temperature creates discomfort, experienced by anyone who sits near both a south facing window and an air-conditioning unit on a hot summer’s day. Surface cooling creates an environment where the air and radiant temperatures are closer together which, with the absence of noise and air movement from an air conditioning unit makes for a more comfortable working environment.

Surface cooling vs air-conditioning

Creating comfortable working environments that save on energy usage when compared with air conditioning.

43

Ceilings & walls

The same principle that makes underfloor heating work can be applied to walls and ceilings. As long as there is sufficient heating area a room can be satisfactorily warmed with a ceiling or wall heating system giving the same comfortable radiant effect as underfloor heating.

The heat output of ceiling and wall systems tend not to be restricted by floor finishes in the same way as an underfloor heating system and can therefore work at even lower water temperatures with the resulting surface temperature being around 30˚C.

The temperature profile of a ceiling heating system is very similar to an underfloor heating system and therefore creates similar levels of comfort. The surface temperature of the ceiling system should be no more than 30˚C to avoid temperature asymmetry which could reduce comfort levels.

In comparison a warm air system creates significant temperature stratification with high temperatures near the ceiling and low temperatures near the floor, not only does this feel uncomfortable but is inefficient especially in rooms with high ceilings.

Timóleon uses high quality PE-RT underfloor heating pipes. The five-layer structure achieves a high degree of oxygen tightness and ensures that this is retained even under rough building site conditions. The entire range is backed by decades of experience in plastics processing. A specially modified polyethylene of medium density is used for underfloor heating systems using PE-RT pipe, the molecular structure and composition of which ensures very good thermal stability and a high degree of mechanical strength. The five-layer pipe structure is manufactured by means of extrusion in one single process. The EVOH layer provides a very good oxygen barrier while the outer PE-RT layer protects the entire structure against damage.

The manifold distributes the primary warm water into each underfloor heating circuit. The manifold is the central point for the underfloor heating system, bringing together the warm water feed from a heat source (such as a boiler, heat pump or thermal store), the pipe work from the floor and also the thermostat wiring.

A manifold can serve areas up to 200m2 but installation is easier if a manifold is installed in accessible locations on each floor. The size of the manifold depends on the area it is serving.

The Timóleon Axios manifold provides all the functionality stipulated by British Standards (BS1264-4) for an underfloor heating manifold. A mixing valve and circulator can be added to the manifold to reduce the water temperature to that needed by the underfloor heating system. The Axios manifold is available with a pre-assembled mixing valve and “A” rated Grundfos Alpha 2L circulator.

All types of floor finish can be used with underfloor heating providing the resistance of the finish is considered. A highly resistive floor finish will slow the flow of heat into the room. Typical floor finishes such as timber and carpet are regularly used with underfloor heating.

Some finish manufacturers stipulate maximum surface temperatures, underfloor heating will create a floor surface temperature of approximately 26°C for most applications however some systems where the building heat loss is high will have surface temperatures up to 29°C. Underfloor heating systems should not be designed to operate at floor surface temperatures higher than 29°C. If your intended finish is greater than 1.5 Tog then please call us and we will check the performance of the underfloor heating.

It is important to ensure that when laying this product over a concrete subfloor that the subfloor is completely dry otherwise bubbling may occur. The relative humidity of the subfloor should be no more than 75% (measured as specified in BS 8201).

Timóleon has long experience of how good UFH is the best way of caring for a hardwood floor. Timber changes dimension due to changes in its moisture content, and this varies naturally throughout the year. The important issue is to keep the moisture content of the upper and lower surfaces of the timber the same. If they do, the timber floor will stay perfectly flat. If they don’t, it could crown or cup.

The first key is to lay the timber floor with moisture content at 8-10%. The second is to ensure the UFH turns on gradually at the beginning of each heating season, which can be assured by using programmable room thermostats and leaving the heating on. The heating will then run briefly, and only as necessary, allowing time for absorbed moisture to naturally respire into the room.

These materials have a low thermal resistance that makes them very suitable for underfloor heating. Consideration must be given to expansion gaps and the suitability of adhesives used to bond the tiles to the subfloor.

Timber Floors Linoleum & vinyl tiles or sheet

Carpet

Ceramic & Stone

Our general advice is to avoid carpets and underlay having thermal resistance greater than 1.5 Tog. However, tests carried out at BSRIA on 24 different combinations showed that some with higher published resistance than this work well over UFH. Timóleon understands the results of these tests, which measured the difference between Published Tog and Effective Tog, and can advise accordingly.

BS 8204 part 2 provides details on spacing and positioning of joints within a concrete screed.

The British Standard for underfloor heating, BS 1264 part 4, states that there should be joints in stone and ceramic finished screeds every 40m2, with a maximum length of 8m between joints. A joint must be placed at least every 8m across the floor but as the joint is only one third of the screed thickness it should not interfere with the underfloor heating pipe provided the underfloor heating circuit has been fixed down securely. Only flow and return pipe should pass through movement joints. Where this happens a 300mm piece of conduit should enclose the pipe and span the joint.

Laying screeds in Underfloor Heating

Drying of screeds

There are many different types of screed from the conventional sand/cement screed to proprietary liquid screeds. The screeds that are discussed here are floating screeds i.e. they are not bonded to the concrete subfloor.

Sand/cement screeds – The minimum thickness of a floating screed is 75mm for commercial installations and 65mm for domestic installations. There should be a minimum of 50mm screed over the pipes (BS8204-1).

Calcium sulphate and anhydrite screeds – The benefit of using this type of screed is that the drying time is less than conventional sand/cement screeds and there is less shrinkage. The minimum thickness of a screed in a commercial installation is 40mm and 35mm in a domestic installation. There should be a minimum of 25mm screed over the pipes (BS8204-7).

Pumpable self-smoothing screeds – There are many proprietary screeds on the market. Advice should always be sought from the manufacturer.

As a rule of thumb a 50mm sand/cement screed could be expected to dry in good conditions within 2 months and a 75mm screed around 3 months.

BS 1264-4 states that sand cement screeds should not be heated for at least 21 days after laying and with anhydrite screeds 7 days after laying. The screed manufacturer’s instructions must alwaysbe followed.

Once the screed has dried the system can be turned on but the screed must not get any warmer than 25˚C for the first 3 days or 15˚C above the temperature of the unheated floor.

UFH FAQs:Concrete Screeds

After this period the system can be switched to the maximum temperature and kept there for 4 days. The underfloor heating must never be used to dry the screed.

It is important that the screed must be allowed to cool to room temperature before the final floor finish is laid.

Underfloor heating systems can be designed to react very quickly to heating demands. The warm-up time of the system depends upon several factors.

The time taken for the underfloor heating system to emit heat is dependent on the characteristics of the floor in terms of the construction, pipe centres and the floor finish and also the temperature of the water used in the underfloor heating system. Underfloor heating with pipe embedded in a thick concrete slab will have a longer warm up time than dry construction systems such as those used in suspended, batten or floating floors. This is recognised in SAP with timber floor underfloor heating having a better overall SAP rating than concrete underfloor heating.

The room warm-up time is also dependent on the heat loss of the building. The underfloor heating system must be sized to overcome the heat losses of the building but also have additional capacity to ensure a good response time from cold.

The cost of running an underfloor heating system depends on the heat loss of the house, how often the heating system is running, the cost of the fuel or electricity and the type of heat source. So it is difficult to predict running costs although studies have shown that heating systems using low water temperatures will be the most efficient and have the lowest running costs. Good underfloor heating, as it is a large surface area emitter, will run at the lowest water temperatures.

The underfloor heating heat output is based on a number of variables:

Floor finish - floor finishes have different thermal resistances. Tiles for example are very conductive whilst a combination of carpet and underlay is less conductive. Also, the thicker the material the lower the heat output will be.

Water temperature – the higher the mean water temperature (the average between flow and return temperature) the higher the heat output.

The underfloor heating product and the construction it is put into – Timóleon products are designed to have a strong conductive pathway from pipe to the floor surface. Some competitor's products have an air gap which reduces the heat output.

Timóleon has tested its systems at BSRIA and is able to provide information on the heat output for your specified construction.

When installing underfloor heating it is important that there is an underfloor heating design showing where the pipe is in the floor, how close the pipe is together and what product is being used as the heat emitter. For simple systems the design can be produced by the installer and does not need to be a formal CAD drawing. However Timóleon provides a full design service for all orders showing where the pipe and product sits in the floor along with the balancing settings for the installer to commission the system.

Introducing the Aura system from Timóleon. Bringing you innovation and style.

Effective controls are essential in creating a comfortable living and working environment. This not only means controlling the temperature in a room but making sure the system runs only when it is needed. To do this the controls not only have to be accurate but easy to use.

The Aura system is flexible, holistic and intuitive to use. It can accurately control the room temperature, program the hot water system and change the ventilation demand through one central touchscreen interface, the ControlPad.

The Aura thermostat is a discreet, attractive fully programmable room thermostat. It can be used on its own or in conjunction with the ControlPad. The Aura sensor provides the same level of room control without the user interface. The sensors can be located discreetly within each room but collectively controlled by the central ControlPad. This makes controlling the system easier, rooms can be switched off as a whole as well as making the room controls tamper-proof.

Aura is an innovative, stylish and holistic control system.

Whether using room thermostats or sensors the ControlPad gives the user a simple way to control all of the heating zones together. One-touch functions are displayed on the ControlPad that make controlling the whole heating system straightforward and intuitive.

Stylish all in one touchscreen allows complete control from one, simple interface.

The ControlPad brings together the multitude of controls present in a modern day home such as the room thermostats, domestic hot water timer and ventilation boost.

The time settings for the hot water system can be set from the ControlPad removing the need for a separate timer.

The whole house ventilation system uses the boost function to quickly bring in fresh air and remove any odours. The ventilation system also has a summer bypass facility that brings in cool fresh air during the summer.

The home screen has been designed for simple one-touch control of all the shortcuts and boost functions. There are no complicated programs to activate each function. All of the system settings are accessed through one button on the home screen and if you’re in doubt there is an information page on each screen.

The settings for the one-touch buttons on the home page are set up here. The interface has been designed to be intuitive and simple to use yet without compromising on any of the features that a homeowner might need.

This function enables the user to lock or limit certain thermostats so that they can only be adjusted by a set amount. For example, in a school or nursing home the caretaker using this function can set certain thermostats so that they can only be adjusted by, say, 2˚C or locked altogether. This prevents tampering leading to unnecessary heating.

The user can define the temperatures required throughout the day. This is displayed graphically to show when the rooms are scheduled to get warmer. The heating profiles are then applied to each zone. This simplifies programming as the user can simply change the profile rather than changing the settings for each zone on each separate day.

Reduce energy consumption and improve the air quality with whole house ventilation.

Whole house ventilation provides a controlled way of introducing fresh air into the building removing the need for trickle vents above windows or opening windows at night. The system also extracts the damp stale air from kitchens and bathrooms.

This outgoing air is warm and this energy in a normal mechanical ventilation system would be lost outside. The Heat Recovery Unit has an integrated heat exchanger that transfers the energy from the outgoing air to the cold incoming air thereby minimising the heat loss due to the mechanical ventilation.

60

A Mechanical Ventilation and Heat Recovery (MVHR) system extracts the stale humid air from bathrooms and kitchens in the same way as conventional mechanical ventilation but instead of dumping the warm air outside the air is moved through internal ducting to a central Heat Recovery Unit (HRU) located in the loft or in a cupboard.

The HRU passes the outgoing air through the heat exchanger whilst simultaneously drawing fresh air from outside in the opposite direction. This process recovers up to 90% of the heat that would otherwise be lost whilst supplying fresh air in a controlled way throughout the building.

By extracting the damp air from bathrooms and kitchens condensation problems are reduced as well as mould growth and the build-up of pollutants. In addition the living environment is improved as windows do not need to be left open reducing noise, pollution and security issues.

What is MVHR and how does it work?

The heat recovery unit transfers the energy from the outgoing warm stale air into the incoming cold fresh air.

The heat recovery unit supplies fresh air through ducting into living rooms and bedrooms through valves in the ceiling or wall.

Outside air is drawn into the house through a roof cowl or air brick.

Ì Eliminates noise from extract fans located within bathrooms

Ì Low maintenance Ì Less dust

Introducing fresh air into a house and extracting the stale air is essential to maintain comfort levels, to alleviate the potential build-up of contaminants and to reduce humidity in bathrooms and kitchens. Part F of the building regulations makes it mandatory for new homes to be properly ventilated. Mechanical extracts are usually installed to remove stale and humid air from bathrooms and kitchens. However the energy present in the warm air is lost when extracted outside, the heating system is then needed to reheat the incoming air.

The transfer of energy from the outgoing stale humid air to the incoming fresh air reduces the need for the heating system to re-heat the air. This saves energy and reduces the running costs of the heating system.

Key benefits of MVHR Systems Heat from ventilation loss is the single biggest component of energy loss in a modern building especially in Passivhaus design. This is because, no matter how air tight the building is, fresh air is always required and this needs to be heated. This supply of fresh air is conventionally provided by extracting stale air using mechanical ventilation from bathrooms and kitchens with fresh air coming from window vents in other rooms. The heat loss from mechanical ventilation can be significantly reduced by using MVHR to control and recover the energy that would otherwise be lost.

Our ventilation systems use the latest semi-rigid duct technology removing the need for many of the fittings required in a rigid duct system. As this is smaller and more flexible it is an easier and faster installation that suits both new-build and refurbishment.

By having less fittings and easy push fit joints air leakage is reduced and the single duct run to each room results in significantly less cross talk noise.

Installation is up to 50% faster than conventional rigid duct systems especially in suspended floors.

Mechanical Ventilation and Heat Recovery (MVHR) systems consist of a central Heat Recovery Unit (HRU) located in the loft or in a cupboard with connected duct running to all the rooms in a house.

The HRU has two fans, one to extract the damp, warm air from bathrooms and kitchens and one to bring in fresh filtered air from outside. The HRU passes the outgoing air through the heat exchanger whilst simultaneously drawing fresh air from outside in the opposite direction. The two air streams are isolated from each other as they pass through the heat exchanger with the warm stale air transferring energy to the cooler incoming fresh air which is then supplied to bedrooms and living areas.

This is used for passing ductwork through a roof.

The manifold is used as a distribution system receiving air through 150mm duct from the Heat Recovery unit and distributing the air into each room using several smaller 75mm semi-rigid ducts. With inherent insulation and sound attenuation properties, this also helps prevent condensation and limit the escape of heat and noise, reducing the requirement for duct silencers.

Supplied in neatly coiled 50m lengths it is easy to handle, store and transport. Its smooth inner lining and strengthened corrugated outer layer are made from Low Density Polyethylene (LDPE) which makes it flexible in its application but hard wearing on site. It can be easily manipulated to changes in direction reducing the need for connectors and T-pieces and saving time on installation, however where sharper bends are required, there is a 90° bend and straight connector available.

The manifold connector provides an air tight seal for the 75mm semi-rigid duct as it is connected to the manifold. This reduces the need for traditional sealing methods such as mastic. Overall this improves the system performance by reducing air leakage.

This duct to room outlet adaptor moves the air from the ø75mm duct through 90° to a standard air valve connector. This reduces air speed on room entry, eliminating draughts and noise.

The ø150mm duct runs from the Heat Recovery unit to the manifold. Its insulating properties prevent condensation and limit the escape of heat and noise, reducing the requirement for silencers.

Used as a terminal fitting at an external wall.

The Heat Recovery Unit uses fans to extract air from inside the building and also introduce filtered air from outside. The two air flows pass through a high efficiency heat exchanger. Each Heat Recovery Unit has a summer bypass fitted.

Timóleon MVHR systems have boost and summer bypass control.

What do you need?

Does the system run all the time,all year round?

Yes, the system constantly runs moving air at a low volume in and out of the building. The system will only operate on “boost” when activated.

What is the running cost of an MVHR system?

The electricity consumed by the MVHR system is very low and this is easily offset by the heat energy saving. The running cost will vary but is in the region of 25p to 30p/day.

What will happen if there is no power?

If the MVHR system should not operate over several hours you will begin to notice the room becoming stuffier especially in bathrooms however there is no risk of suffocation.

Is it noisy?

In continuous mode the HRU is barely audible. In boost mode because of the extra volume extracted the noise is increased slightly to 35dB at 3m (a computer is typically 40dB).

60 years ago, the concept of circulating high temperature water from a boiler through radiators fitted in each room was still new. Since then, it has become the standard way of heating most buildings in the UK. The consequence is that more than 99% of the buildings in the UK are now dependent for their heating on a central boiler which uses a fossil-fuel.

Yet we all know that these fuels are becoming increasingly more expensive. Government figures record that 4 million UK households were already in “fuel poverty” in 2009.

Despite this, we continue to fit new buildings with heating systems that are dependent on high temperature fossil-fuel boilers.

What is the alternative?

The recent big change has been the development of a new generation of high-performance underfloor heating products, for both retrofit and new build, which are able to provide very comfortable and effective heating while using water which is only 35-45˚C. Along with this, a new generation of solar thermal technology has been developed that can more effectively store and use the energy collected from solar thermal even on a winter’s day.

These two developments - low temperature underfloor heating combined with a clever solar thermal storage and control system - mean that up to 40% of the building’s heat load can be satisfied by energy collected from the sun.

Lower bills, faster payback and less reliance on fossil fuels.

Timóleon underfloor heating systems are designed to use low water temperatures, low enough to use the heat collected by a solar thermal panel.

Timóleon SunCylinder. Using solar thermal energy for the heating system.

66

So

lar Heating

Simply, solar thermal panels during the winter have far less incident solar energy than in the summer. In these conditions the solar panel can still collect a reasonable amount of energy but at a low water temperature which isn’t useable by most heating systems such as radiators.

Solar thermal can be used to contribute to the heating system. There are four dimensions that are crucial to making this work:

1. Heat emitters designed to work at low water temperatures.

2. A control system that recognises when the stored low temperature water can be used for the heating system.

3. A way of storing the water to make best use of it for both the heating and hot water.

4. An efficient and correctly sized solar array.

Timóleon underfloor heating systems are designed to be effective when using low water temperatures. This means that the energy collected and stored by the solar thermal panels during the winter, autumn and spring can be used without the need to automatically run the boiler or heat pump. The SunCylinder system provides the necessary storage and control to make this work.

Why don’t we normally use heat collected from Solar Thermal in our heating systems?

How do we use solar energy in our heating systems?

67

The SunCylinder system works by making full use of energy collected by the solar thermal panels even when this is stored at relatively low water temperatures.

The SunCylinder system has a unique control that calculates the required heating system water temperature, if this required temperature is lower than the water in the cylinder then it will use this stored energy before firing the boiler.

For example when the weather is very cold, say -3˚C, then the underfloor heating system may need water at 45˚C but when the outside temperature is higher, around 8˚C, the required water temperature will be lower, say 35˚C. If the water in the cylinder is above 35˚C the control system uses the heat stored in the cylinder rather than activate the boiler or heat pump. As soon as the water temperature in the cylinder drops to an unusable level then the boiler or heat pump is used. This method of control makes better use of the solar thermal energy.

A conventional heating system will fire a boiler when there is demand, heating up the thermal store to 60˚C or 70˚C regardless of what temperature is needed by the heating system. When water is stored at this high temperature it is impossible for the solar thermal to be able to store any further energy collected from the panels.

Total House Load Hot water and heating from Solar

A standard twin coil solar cylinder is expected to provide 60% of the hot water load throughout the year. The hot water load is 25% of the home’s energy load therefore a twin coil cylinder provides 15% of the home’s energy use.

Alternatively, some systems use a three coil thermal store for heating and hot water. However, on demand, the thermal store will have to heat the stored water to a fixed temperature, usually 65˚C or 70˚C. The use of the solar thermal during the spring, autumn and winter becomes limited as storing water at high temperature makes it impossible for the solar thermal to contribute energy collected at low temperature.

What makes our system different?

Compare this to SunCylinder. SunCylinder is primarily designed to be used for heating rather than hot water. The SunCylinder system is designed to contribute up to 40% of the heating load for the year. As the home’s heating load is 75% of the total load then the SunCylinder system can contribute 30% of the home energy PLUS some of the domestic hot water demand especially through the summer months. SunCylinder has a much faster payback as a result, between 6 and 15 years depending on the type of fuel, the solar thermal input and how the heating system is used.

What is the SunCylinder system?

A unique patented cylinder design is used in conjunction with a control system.

The cylinder has two input coils, one coil for solar thermal and a second coil for the auxiliary heat source, this coil is sized so either a boiler or heat pump can be used.

The third output coil supplies the Timóleon underfloor heating system. The cylinder has the same footprint as a conventional cylinder with all the coil and sensor connections located conveniently on one side.

The control system uses a pre-assembled “jig” for simple onsite installation, this includes the necessary valves and circulator. The electronics are contained within the control box and provides an easy way to set up and commission the system as well as providing connection for the sensors and valves.

The training addresses the total amount of energy used by UK buildings and how this must reduce. It introduces the European Energy Performance of Buildings Directive, EEPBD, which drives Building Regulations Part L. The training explains the science behind how UFH and radiators work, and how this relates to the new design principles. It describes the constituent elements of any UFH system, how these inter-relate and how these elements differ from the elements of a radiator system. The training goes into some detail, showing how UFH can be incorporated into any form of floor construction, including acoustic floors. Finally, the training considers how UFH works in conjunction with the whole range of different floor finishes, and concludes with its relevance to Renewable Energy.

Where we are currently in the UK with regard to Renewable Energy, what are the pressures and consequences of the Government’s national CO2 target and what we have recently learned about how to reduce a building’s CO2 level. The training proposes steps we have to take in order to reduce the amount of energy a building uses in the future, and it’s CO2. The training considers Renewable Energy technologies collectively and then discusses them individually, explaining how they inter-relate. Finally, the training explains which key steps need to be taken first in order that other phases of RE can be more easily added to a building later in its life.

Ì New Build at both the design stage and ‘As Built’ Ì For change of use, extensions, renovations and refurbishments

We can work from a supplied specification whilst also looking at site specific alternatives that could be incorporated to improve the overall efficiency and rating of the building. We can also look at finished projects that have failed at the ‘As built’ stage and work with clients to find the most cost effective solutions for achieving a pass.

Reducing energy consumption is vital. With Tonos, we can help you do it.

Tonos focuses on a whole house approach working closely with clients to provide a strategy to meet their design requirements, from bespoke buildings through to large developments.

We provide a number of energy consultancy services to help you specify the right system for your project.

MCS (Microgeneration Certification Scheme) Heatlosses

We provide heatlosses for all project types and technologies, including biomass, gas and all types of heat pumps. It is now a requirement for heatpump technologies to provide compliant heatloss calculations in accordance with MIS3005. This standard requires that specific criteria for the heat loss calculations are met and assesses whether the heat pump and heating emitters (UFH and radiators) meet the room by room calculations. As part of the Renewable Heat incentive (RHI) it will be necessary to confirm that the heat pump and emitters meet 100% of the heating load.

As part of our report we will provide information on the energy consumption and potential running costs. Tonos also provides comparative running costs set against other renewable technologies and fuel types. We can also provide;

Ì U value calculations Ì Site surveys/ thermal imaging Ì Recommendations/ advisory notes for improvements to the building

Renewable Feasibility and strategy

Tonos will assess the project, site and surrounding area to provide a balanced report that details all the renewable energy options that are practical and financially viable. We will provide bespoke and impartial information which will guide your decision making, providing detail on recommended technologies with informed considerations for installation. Our reports also provide information on potential payments through the Renewable Heat Incentive (RHI), Feed in Tariffs (FITS) and payback periods for your investment. Tonos understand concepts for low carbon developments, promoting low embodied energy materials and sustainable design concepts.

Placing an order

Getting a quote and specification

Orders can be placed through your local merchant. They will need to know when the goods are required and the site address (unless it is being delivered to the branch) and a copy of your quote. The merchant will then call the Project Manager to organise delivery.

From order we will provide a comprehensive underfloor heating design for your approval. Once agreed the materials will be dispatched and sent to site or the branch as required. Depending on design approval the process will take up to 10 working days.

To get a quote simply email your plans to [email protected] or use the online facility at timoleon.co.uk. We have provided a quote request form at the back of this brochure should you wish to fax or post your plans.

When sending in your plans please provide details of the floor construction, the floor finishes and the type of heat source. We would also like to know the insulation levels and glazing type. If it is a new build then simply state “built to current regs”.

There are product specifications on all of our published datasheets. However, if you would like to discuss your project with us then please call the project team.

At Timóleon, we are committed to providing the highest quality service, with dedicated project managers assigned to your project from quote to install.

Timóleon provides a comprehensive quoting and specification service. However, we appreciate that sometimes a quick price is needed without the specification and detail.

Simply send your plans to us with details of the floor construction and we will get a price back to you within 24 hours. If you need a more thorough room-by-room quotation and specification then please allow a bit longer.

When we receive an order our standard procedure is to produce a detailed design and issue for approval before we then dispatch the materials. However if materials are needed in a hurry then Express Delivery offers a quick but simple way of getting standard products to site with a design for projects under a 100m2.

Once we have received the order from the merchant we will aim to have the materials on site within 48 hours. We will produce the underfloor heating design as normal but rather than issue for approval we will dispatch the plans with the materials. As there is no time for design approval any on-site changes have to be met by the materials sent.

Underfloor heating systems are often considered the most comfortable way of heating a building. However, the performance of an underfloor heating system is often unknown as there are several factors that influence the heat output i.e. the construction, the method of transferring heat from the pipe into the floor, the floor finish and the water temperature.

Timóleon has developed this application to enable specifiers and installers to understand how well systems work with certain floor finishes and water temperatures. This can then be used to compare with the building heat losses.

It is important to know that using a different floor finish won’t make the underfloor heating system ineffective. Equally, will the heat output from the underfloor heating be enough if a heat pump is installed working at low water temperatures?

With the Timóleon app you will be able to tell what the floor surface temperature will be at certain heat outputs, making it a vital tool for specifiers and installers alike.

The free Timóleon application is simple to use and produces accurate algorithms for your underfloor heating project.

The data provided by this app is indicative and applies only to Timóleon systems and products. Please contact Timóleon for project specific data.

Timóleon's pioneering free underfloor heating app updated with our latest range of underfloor heating products for all types of floor constructions.
