Exhaust air heat pumps

An exhaust air heat pump is the perfect solution for single-family homes and terraced houses where you want to minimize energy consumption and utilize the building's own thermal energy efficiently.

In housing associations, an exhaust air heat pump helps reduce heating costs and improves ventilation efficiency, which increases living comfort and reduces the property's energy consumption.

An exhaust air heat pump can offer significant savings for office spaces, commercial properties and small production facilities where ventilation is in continuous use and energy consumption is significant.

An exhaust air heat pump (EIHP) uses the indoor air removed from a building as a heat source. It recovers the heat that would normally escape with ventilation and transfers it back to the domestic hot water and heating system. The system combines ventilation, heating and domestic hot water production into one unit.

The efficiency of an exhaust air heat pump, or SCOP value, typically varies on both sides of 3, meaning that the device produces approximately three times more heat energy than it consumes electricity. The efficiency depends, among other things, on the indoor air temperature, the device model and the use to which the heat is directed. The best efficiency is achieved in steady, continuous use.

The installation of an exhaust air heat pump includes dismantling or integrating the old ventilation equipment, installing the new equipment in the technical space, and connecting the ventilation ducts, water, and electricity. The installation usually takes 1–2 days and requires precise site-specific planning, especially in renovation projects.

Exhaust air heat pump is particularly profitable in low-energy houses or new developments where the heat demand is not high and a significant amount of heat energy is removed through ventilation. It is ideal for small and medium-sized buildings where ventilation and heating are to be combined as compactly as possible.
