Tarm Biomass · 4 Britton Lane · Lyme, NH 03768
Appendix B-Overheat Loop: No Electricity
The piping and controls must be connected to the boiler in such a way that in the event of a power fail-
ure there is one loop of radiation available for gravity circulation. This loop must not be obstructed by
any valves or other accessories which would prevent gravity circulation during a power failure. The
piping is plumbed in such a way that excessive pressure will not be developed in any portion of the
boiler or system. The loop must be large enough to dissipate at least 10% of the boiler’s maximum
rated heat output, assuming an ambient temperature of 65 °F (18 ºC) and a mean water temperature of
180 ºF (82 ºC).
The minimum pipe size for this loop is ¾” and if possible, the loop should be located and pitched to
maximize natural thermal convection of the water. The loop must be positioned above the boiler. The
design of the loop must be such that it can be made inoperative only in a deliberate manual action. If
large enough, an existing heating radiation zone may be used for the over-heat loop. The loop must be
equipped with zone valves which will open automatically during a power failure. We recommend
AUTOMAG zone valves for this application (offered as an accessory).

Appendix C-Thermostatic Mixing Valve
A Thermostatic Mixing Valve or Loading Unit must be incorporated into the heating system piping as
shown in the figure below. When the Mixing Valve is used a ball valve (I) (not provided) must be in-
stalled upstream of Port 1 of valve TV-1. The valve should be set at half open (and the handle re-
moved after it is set), in order for the tempering loop to function correctly. If there are unions included
with the Mixing Valve or the Loading Unit, the internal valves must be fully open. A circulator is inte-
grated into the Loading Unit, so a circulator is not required.

TERMOVAR LOADING UNIT is a pre-
fabricated, automatic, thermally operated valve
unit for solid-fuel boiler/storage tank installations,
where heating and domestic hot water are taken
from the storage tank. TERMOVAR LOADING
UNIT ensures a minimum return-water tempera-
ture into the solid-fuel boiler, which increases the
boiler efficiency, prevents tarring and considera-
bly prolongs the lifetime of the solid-fuel boiler.
TERMOVAR eliminates the risk of destructive
thermal shock caused by surges of cold water re-
turn water. TERMOVAR renders a more effective
burning and is therefore a necessary part of a solid
fuel installation with a storage tank.

Termovar Includes:

2. Backflow preventer
3. Circulator pump
4. Three thermometers
5. Three ball valves
6. Insulation EPP
Termovar Loading Unit has several advantages:
The pre-fabricated unit saves time and provides a quick and trouble-free installation.
The loading unit provides a constant loading temperature to the storage tank.
It can be installed on the right-hand or left-hand side of the boiler.
The loading unit is installed on the return pipe which means that the supply pipe is free for
expansion and the unit is never affected by steam in case of an overheated boiler.
Service friendly. All parts can be changed without draining the system.

AUTOMIX 10 is an advanced, compact outdoor
reset control for hydronic baseboard, radiator, and
radiant floor heating applications.
AUTOMIX 10 works continuously and propor-
tionally. Through impulses from the sensors the
control adjusts the supply water temperature as the
outdoor temperature changes.
AUTOMIX 10 includes a min. and max. limiter
for the supply water temperature and a freeze pro-
tection feature. AUTOMIX 10 is delivered factory
wired which minimizes installation problems in
the field. The main supply and all sensors have
plug-in connections. The quick and easy do-it-
yourself installation saves on labor charges.

Termovar Loading Valve The TERMOVAR TEMPERING VALVE is an auto-
matic thermally operated tempering valve for solid-fuel
boiler installations with or without a storage tank.
The TERMOVAR ensures a minimum return water tem-
perature to the heating boiler, which increases combus-
tion efficiency, prevents tarring and considerably pro-
longs the lifetime for the solid-fuel boiler. The TERMO-
VAR eliminates the risk of destructive thermal shock to
both steel and cast iron boilers. The TERMOVAR ther-
mally operated tempering valves render a more effective
burning and are therefore a necessary part of a solid-fuel
boiler installation.
