Split - Air to Water Heat Pump 20220105

3.3 Space Heating, Space Cooling and Domestic Hot Water

Floor heating loops & Heating radiator & Fan coil units are used for space heating , fan coil units are used

for space cooling. Domestic hot water is supplied from the domestic hot water tank connected to the hydronic

box. The unit switches to heating or cooling mode according to the temperature detected by the room

thermostat. In space cooling mode, the 2way valve is closed to prevent cold water entering the floor heating

loops & Heating radiator.
