Air Source Heat Pump FAQs
Will a heat pump work in 0°C weather?
Air source heat pumps will continue to work in sub-zero temperatures, with the limit being around -20°C. Air source heat pumps have been found to be more effective than a conventional boiler in sub zero temperatures.
Do radiators need to be changed with an air source heat pump?
While your radiators don’t necessarily have to be changed, it is recommended to upgrade them to maximise the energy being created. Larger radiators disperse the heat quicker, which works better with the heat pump.
