Exhaust Air Heat Pumps

The technology used with exhaust air heat pumps works firstly to ventilate your house, then return the ventilated air's heat energy to heat the water and the heating system. An exhaust air heat pump thus reuses energy from old consumed air from around the home.

To help simplify, exhaust air heat pumps remove air from wet or cold rooms in your home. Then creating a slight negative pressure to allow air from other areas of the house to circulate where needed. At the same time new outdoor air is drawn in through the valves in the outer walls ensuring all rooms in the home are fully ventilated. Finally, circulated air is taken through the house's duct system and the heated room air is led to the heat pump where the energy in the air is recovered. This process allows the heat pump to supply the entire house with hot water and heat.


Our Exhaust air heat pumps use energy from nature to reduce the environmental impact. They are designed to give you an energy-efficient daily life without compromising on comfort. This is done, for example, by automatically adjusting the heating according to your habits and the weather forecast. All to give you cheaper, greener, and more reliable heating, both now and in the future.
