815 ThermoKit T

  • Complete kit
  • Low-energy pump

LK 815 ThermoKit T 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 consists of a low-energy circulating pump, an LK 823 ThermoVar thermic loading valve with i­nsulation, a check valve, a thermometer for reading return ­temperature and three ball valves to simplify installation and maintenance. The loading group 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, if the need for servicing arise.

Thermometers are available as accessory, art. no. 181736.

LK 815 ThermoKit T 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 normally requires no maintenance. The installation should be checked regularly.
