How exhaust air heat pump works

Exhaust air heat pumps first ventilate your home and then use the heat energy in the ventilation air to heat your water and your home. In other words, an exhaust air heat pump reuses energy from waste air.

Slightly simplified, it is possible for a fan to suck ventilation air out of all wet spaces in your house. A weak negative pressure is then created, which means that air from other rooms also finds its way to the wet areas. Fresh outside air is drawn in through the vents on the outer walls and in this way all rooms in the house are ventilated. The circulating air is taken into the house's duct system, and the heated room air is led to the heat pump where the energy in the air is recovered. In this way, the heat pump can supply the entire house with hot water and heat.

New possibilities – for you and the environment

The principle of an exhaust air heat pump is basically simple, but the development of the technology has created increasingly advanced products over the years. At the same time, our heat pumps have become increasingly easier to install and use. They basically take care of themselves, year after year.

We offer a performance that both guarantees safe operation and great savings, both for you and the environment.
