What is the water flow temperature?

The water flow temperature will vary between 35-60°C, depending on the heat losses from the building. If the system operates with thermostatic mixing valves, use 45°C temperature for screeded floors and 55°C temperature for timber suspended and floating floors.

Some heat pumps will work at 35°C which means the pipe spacing needs to be c/c 150 mm.
