Yes, modern heat pumps operate effectively even in cold UK winter temperatures. The systems we install at Harpenden Heat Pumps are specifically designed for the British climate and can extract heat from the air even when temperatures drop below freezing. While efficiency may slightly decrease in extremely cold conditions, the system remains effective year-round.

In many cases, existing radiators can work with heat pump systems, though some modifications might be necessary. Because heat pumps operate at lower temperatures than traditional boilers, Harpenden Heat Pumps will assess your current radiators during the initial survey. We may recommend larger radiators or underfloor heating in some areas to ensure optimal heat distribution and efficiency.
