The Earth acts as a huge thermal store and absorbs the sun’s energy. Heat pumps extract this solar energy from various sources such as the ground, water or even the air. Although heat pumps need electricity to drive the pumps and compressors they can reclaim more energy than they use and can be integrated with other technologies to make it completely renewable.

Heat pumps work most efficiently with low temperature heating distribution systems such as underfloor heating. The lower the outlet temperature from the heat pump the more efficient the unit is. At a temperature of 35°C, for every one unit of electricity used in a ground source heat pump 4 units of heat energy will be produced i.e. 400% efficient.

As heat pumps use renewable energy they also have low CO₂ emissions compared to traditional heating systems and can cut emission rates by up to 50%.
