The European buildings are responsible of 40% of global

energy consumption. Reduce this share of 20% within

2020, according to European Directive, it means incre-

ase energy efficiency of each building/plant system

by modifying both construction techniques and inter-

action between different components of system.

Conventional technology is based on plants that use traditional

energy sources (usually fossil fuels) integrated with renew-

able energy sources.

Technology of the future means to design systems that use

only renewable sources supported by traditional systems that

operate only when is necessary; the objective is to construct

new buildings able to produce all the energy they need, that is

“zero energy buildings”.

For this reason Watts Industries, always committed to research and development of products that give a real contribution to saving energy by respecting environment, has developed a range of products dedicated to renewable energy sources through three product lines for solar heating systems, for biomass heating systems and for geothermal systems, identified by logos: Watts Solar, Watts Geothermal andWatts Biomass.

Technology of the future

Thanks to so large offer, Watts Industries is the partner for any system solution that integrates different sources of energy to obtain the maximum efficiency combined with traditional products ideally placed in system defined: “integrated solutions for energy

efficiency and comfort”.

4 In the construction and renovation of a thermal boiler room, the adoption of regulation end pumping units (Series PAS, FSAP, PASM), facilitate the managing / control of the heat transfer fluid and of the installation/maintenance works.

Watts Industries produces several new models complete of on-off valves with integrated thermometer, gravity flow stop device, connections and wall mounting brackets, EPP insulation, with 3 way mixing valve modulating or fix point type. The units are ready to mount standard circulating pumps with different lengths (130-180 mm) and Erp ready pumps.

The pumping units are designed following the modularity prin-ciple with the advantage of fast connection and mounting to heating circuit distributors (Series VB32) and hydraulic switch (Series HW and HW-Q60/80).

6The most popular heating system in modern shared

residential buildings is no longer based on individual apartment

generators. It now has better features, characterised

by a highly efficient central output with units connecting

the main circuit and living quarters.

This solution responds to the needs of the user in terms of comfort,

independence and safety, and offers lower operating costs.

The use of heat metering systems allows consumers living in

an individual apartment connected to a centralized heating sys-

tem to play an active role in managing their personal comfort, to

count on large supply of sanitary hot water but with certainty to

pay service on basis of effective consumption

Watts Industries Italia offers a complete range of products and systems for these applications :

• DOMOCOMPACT preassembled units with direct thermal energy metering system for room heating/cooling and sanitary water consumption metering.• DOMOCAL thermal units with direct thermal energy metering system for heating/cooling and instantaneous production of hot sanitary water.• All the components necessary to implement the existing systems: single-jet and multi-jet water flow meters, ultrasonic meters, electronic thermal energy meters for reading and recording consumption in heating and cooling system that support remote data transmission.• Central heating consumption software and equipment with PC data transfer via \bus network or modem connection.

7The European buildings are responsible of 40% of globalenergy consumption. Reduce this share of 20% within 2020,according to European Directive, it means increase energy efficiency of each building/plant system by modifying both construction techniques and interaction between different components of system.European laws are introducing obligation of significant upgrading of boiler rooms and introduction of temperature control thermal energy metering. The heat cost allocation is a process that develops in two stages installation and consumption readout / billing.

Watts Industries, thanks to its experience in the temperature control and energy metering, can offer all devices needed to implement a systems for the heat cost allocation in buildings Watts Industries can offer not only the components for the radiators (cost allocators, thermostatic valves lockshields valves). Watts Industries system allows setting and readout of cost allocators without enter into the houses.

8In buildings, the main aim of the installations is to maintain the best possible conditions inside the rooms while at the same time also optimizing use of available energy resources.

Conditions of comfort are obviously correlated to the specific use made of the rooms. In residential applications, they contribute to the quality of life while in the work place, they also help ensure optimum performance.

Therefore in every heating and cooling systems the regulating devoices like thermostats, chrono-thermostats, valves and actuators, are the most important components because from each directly depends the comfort level.

10The radiant panel heating system is a technique that warranties maximum comfort with low energy consumption.It is also enough to supply to cold liquid to the radiant panel system to obtain with a unique solution, a system that can be used for heating in winter and cooling in summer time.Thanks to the improvement of the performances of construction and insulation materials, the building energy request continuously decreases.

For these reasons the radiant panel heating systems can be supplied with two different ways:

- With high temperature fluid, mixed before being sent to the radiant circuits - With low temperature fluid produced by condensing boilers or heat pumps.

15To obtain uniform temperatures inside buildings, reducing energy costs and prevent problems of systems, the real flow rates have to correspond to the theoretical calcula-ted values. This correspondence, often disregarded with serious consequences on the good working of the systems, is not easy to be obtained only working on piping diameters.

The installation of balancing devices, like valves series FO-BV and WATTFLOW, solves this problem and allows both in the design phase and especially in the field to have devices easy to use to perform balancing and testing.

Especially the valve Series FO-BV, based on the Venturi principle, has a calibrated orifice that allows, when used with the balancing instrument (Series BVT-SET), to quick measurethe instantaneous flow rate and to adjust it by rotatingthe handwheel. Once the calibration is done, it is possible mechanically fix the setting value.
