Loading Units | LK 811 ThermoMat E Eco LK 811 ThermoMat E Eco Technical Data 22 Registered Patent Pending ErP ready 2015 Design LK 811 ThermoMat E Eco 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 E Eco is a compact design with an integrated low-energy circulating pump, that fulfills the requirements of ErP 2015, 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. LK 811 ThermoMat E Eco is available with or without an electronic temperature controller. Mounting kits for controllers of other brands are available - see page 96. LK 811 ThermoMat E Eco 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.

Heat up phase The water circulates between boiler and loading unit while the temperature of the boiler is rising. 2. Loading phase The mixing valve 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 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 selfcirculation. The check valve also stops recirculation from storage tank to boiler.
