Recommended Boiler and cylinder temp settings | AVForums

Oct 08, 2021 · If I set the boiler to 65c and the cylinder thermostat to 60c, the hot water from the hot tap reaches approx 40c max. If I leave the boiler at 65c but bump the cylinder to 70c the hot water remains at 40c and the pump runs constantly. If I increase the boiler temp to 75c, then I get hot water at about 50c and the pump turns off.

Fundamentals Of Hydronic (Hot Water) Radiators | Castrads

Ground- and air-source heat pumps are an immensely important part of the decarbonisation of home heating and we expect their usage to increase. The water in a heat pump-powered heating system is not as hot as from a traditional gas-fired boiler, and that reduces the output of the radiator. Typically, the mean water temperature from a heat pump
