LK 551 HydroKit Solar is a valve combination, designed to

energy optimize water heating from two different heat sources.

In order to maintain the set water temperature, the warm water

from one heat source is mixed and led directly to the mixed

water outlet or if needed diverted to an other heat source for

further heating.

LK 551 HydroKit Solar has two thermic valves; one diverting

valve and one mixing valve with anti-scald function. The warm

water temperature, for the mixing valve, is adjustable within the

range of 35 °C to 65 °C and for the diverting valve the tempera-

ture is adjustable within the range of 42 °C to 52 °C.
