CAPACITY DIAGRAM

LK 551 HydroKit HWC is a compact unit for hot water circula-

tion. Hot water circulation offers instantly available hot water at

a tap, so you don ́t have to wait on hot water. Hot water circula-

tion is especially useful in buildings with long water pipes.

LK 551 HydroKit HWC consists of a mixing valve, cross, con-

nection kit and 3 check valves, to prevent self circulation. The

mixing valve has a thermostat that regulates the supply of both

cold and hot water to the desired temperature. The valve has an

anti-scald function that closes for incoming hot water in case

the cold water supply ends.
