LK 810 ThermoMat 2.0 G is a loading unit for heating applications
with solid fuel boilers and storage tanks. The loading unit is intended
to ensure a high return temperature as well as an optimal temperature
stratification in the storage tank, thus increasing the efficiency of the
system. Tarring and condensation are prevented which prolongs boiler
life.
The LK 810 ThermoMat 2.0 G is a compact design with an integra-
ted low-energy circulating pump, that fulfills the requirements of ErP
2015, and a thermic loading valve that regulates on two ports. The
loading unit has three ball valves to simplify installation and main-
tenance, three thermometers that allow for simple control of the lo-
ading process and an insulation to minimize heat loss. The loading unit is
available in two versions - with or without check valve. With a check
valve the functions described under phase 4 will be obtained.
LK 810 ThermoMat 2.0 G is also available with a circulating pump that
is controlled by a PWM-signal. For more information please contact
our sales department.
LK 810 ThermoMat 2.0 G is installed in the return circuit between
the solid fuel boiler and the storage tank. The unit should be mounted
upright with the drive-shaft of the circulating pump in a horizontal
position. The loading unit is reversible and can easily be adapted for
mounting to the right or left of the boiler.
The loading unit normally requires no maintenance. The installation
should be checked regularly. Thanks to the three ball valves any part
can be changed without draining the system in case of servicing.

TECHNICAL DATA
The function of the loading unit during the
different phases of heating:
1. HEAT UP PHASE
The water circulates between boiler and
loading unit while the temperature of the
boiler is rising.
2. LOADING PHASE
The thermostatic element starts to open and
allows return water from the storage tank to
be mixed with supply water before it returns
to the boiler. The return temperature to the
boiler is kept constant.
3. END PHASE
The thermostatic element is fully open and
the bypass is closed. This results in an opti-
mal transfer of heat from the boiler and the
storage tank is filled with supply water.
4. SELF-CIRCULATIONWITH CHECKVALVE
Self-circulation will be obtained as soon
as the fire has gone out and the circulating
pump has stopped. The remaining hot water
is loaded to the storage tank. In case of power
failure or pump breakdown the check valve
automatically opens to allow self-circulation.
The check valve also stops recirculation from
storage tank to boiler.
