ErP ready 2015 27 LK 815 ThermoKit T Eco Technical Data LK 815 ThermoKit T Eco is a loading group for heating applications with solid fuel boilers and storage tanks. The loading group 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. LK 815 ThermoKit T Eco consists of a low-energy circulating pump, that fulfills the requirements of ErP 2015, an LK 823 ThermoVar thermic loading valve with insulation, a check valve, a thermometer for reading return temperatures and three ball valves to simplify installation and maintenance. LK 815 ThermoKit T Eco is installed in the return circuit between the solid fuel boiler and the storage tank. The group should be mounted with the drive-shaft of the circulating pump in a horizontal position. The loading group is reversible and can easily be adapted for mounting to the right or left of the boiler. The loading group 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, should the need for servicing arise. The function of the loading unit during the different phases of heating: 1. Heat up phase The water circulates between boiler and loading group while the temperature of the boiler is rising. 2. Loading phase The thermic 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 thermostatic element is fully open. This results in an optimal transfer of heat from the boiler and the storage tank is filled with supply water. 4. Self-circulation As soon as the fire has gone out and the circulating pump has stopped the remaining hot water in the boiler is loaded to the storage tank as long as the thermic valve remains open. When the boiler has cooled the thermic valve closes. The check valve prevents recirculation from storage tank to boiler.
