General Information
LK 810 ThermoMat G is an automatic loading unit for solid-
fuel boiler/storage tank installations. The loading unit ensu-
res a minimum return-water temperature into the heating boiler,
which increases boiler effi ciency, prevents tarring and considera-
bly prolongs the lifetime of the heating boiler.
LK 810 ThermoMat G eliminates the risk of destructive thermal
shock caused by surges of cold return water and renders a more
effective burning. The heating boiler quickly reaches the right
working temperature. In the end phase of the fi ring an automatic
balancing valve closes the by-pass loop. This results a maximum

cooling of the boiler and the storage tank is fully fi lled with hot
water.
LK 810 ThermoMat G automatically allows self-circulation as soon
as the fi re has gone out so that the rest of the heat in the boiler is
transferred into the storage tank. It also allows self-circulation in
case of power failure.
LK 810 ThermoMat G loading unit is normally service free. The
valve unit has three ball valves. Any part can be changed without
draining the system.
