Contrary to popular belief, heat pumps can effectively extract heat from outdoor air even when temperatures drop below freezing.

Norway is the largest adopter of heat pumps with two-thirds of households having their heat pump installed, more than anywhere else in the world. This is a prime example of how well heat pumps can work in very cold conditions.

Its essential that the sizing of the heat pump matches the demand in the building for the heating, cooling and hot water needs all year round. This is sized through detailed heat loss calculations. There can be marginal drops in efficiency when it is very cold however heat pumps remain the most efficient way to heat a home.

Positioning of the heat pump is also important, Air Source heat pumps need space around them so that the air can move through the heat pump and dissipate rather than being sucked back in.

We partner with Samsung who test their heat pumps at -25 °C, so no danger of them seizing up in UK winters.
