What are Exhaust Air Heat Pumps?

Exhaust Air heat pumps primarily ventilate your house with recirculated air, then uses the latent heat energy contained within the used air to heat the water and the heating system. An exhaust air heat pump simply reuses energy from old consumed air from around the home. 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. This system is particularly suited to smaller properties and apartments.
