How hot will my radiators be?
Radiators connected to a heat pump system typically feel warm rather than piping hot—usually running at around 35–55°C instead of the 70–80°C typical of gas boilers. This gentler heat may feel different at first, but it’s actually a key part of how heat pumps work so efficiently.
Instead of short bursts of high heat, heat pumps maintain a more consistent, comfortable temperature throughout the day. This means no more hot-and-cold cycles, just steady warmth that’s better for energy savings, comfort, and the environment.
