firstly, floor heating control:

the hot water of storage in

hot water tank

1, 1

st stop valve

13, 2 nd stop valve 14 are closed, and 3 rd stop valve 16 is opened, through 1 st working shaft 15 hot water along the heat exchange tube of the pump-in heat pipe of underfloor heating system 2 of the tube-in-pipe that communicates, through the heat that the heat exchange tube released, absorbs air cooling volume in the service environment, improves air temperature, reaches the effect that improves service environment air temperature.
