Heat Pumps | Exhaust Air Systems

Exhaust Air Heat pumps work by extracting excess warm air from your kitchen, bathroom or utility room, through a ducting system installed in the ceiling, and removing the thermal energy from it into the heat pump.  The cooled air is then discharged outside whilst the heat is retained in the system which in turn can be used to heat your hot water and for the heating system of the building itself.

An exhaust air heat pump system can also help to ventilate your property, by drawing excess warm air into the heat pump system, fresh air is forced into the kitchen, bathroom or utility rooms – giving you better ventilation and air circulation in the property.

Exhaust air heat pumps can provide a very effective renewable energy solution for smaller properties or for apartments and flats.  Units typically measure around 2095x600x615mm and can be placed in a utility room or boiler room in an apartment block.
