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.

Application

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 electronic temperature controller starts to open the mixing valve at the chosen temperature 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 mixing valve is fully open towards the storage tank. This results in an optimal transfer of heat from the boiler and the storage tank is filled with ­supply water. When the boiler has cooled the electronic controller LK 100 SmartComfort CT ­prevents ­re-circulation from ­storage tank to boiler.

4. Self-circulation with check valve

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.
