Detailed Information

Description

LK 811 ThermoMat 2.0 W 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 811 ThermoMat 2.0 W is a compact design with an integrated low-energy circulating pump and a mixing valve that ­regulates on two ports. The loading unit has three ball valves to simplify installation and maintenance and an insulation to ­minimize heat loss. Three thermometers that allow for ­simple control of the loading process can be ordered as accessories.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. The loading unit is ­reversible and can easily be adapted for mounting to the right or left of the boiler. Thanks to the three ball valves any part can be changed without draining the system in case of servicing.

LK 811 ThermoMat 2.0 W is available with or without an electronic temperature controller. Mounting kits for controllers of other brands are available - see section Temperature Controllers - Mounting Kits.
Please contact our Sales Department for more information.

LK 811 ThermoMat 2.0 W 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 normally requires no maintenance. The installation should be checked regularly.
