Exhaust Air Heat Pumps
Exhaust Air Heat Pumps
An advantage of using an exhaust air heat pump is that you use the indoor air e, which is always warm, as an energy source. The energy content of this indoor air is considerably higher than cold outdoor air. Another advantage is that the dwelling’s extract ventilation is provided for within the heating system. The indoor air becomes comfortable and no separate ventilation fan is needed.
While exhaust air heat pump systems are relatively new to the Irish market, we at Unitherm are no strangers to the technology. At Unitherm we select our exhaust air heat pump suppliers based on two key parameters, their system performance, and the innovation present in their units. The design and integration of exhaust air heat pumps into any project requires a total building evaluation and carefully attention to detail.
Our team of engineers are industry experts in exhaust air heat pump technology and have developed our own in-house software ‘Unicalc’, to design systems to the highest standards with particular emphasis placed on enthalpy calculations. From system design, to compliance and commissioning, you’re covered with Unitherm.
EAHP
500% +

The EAHP has a COP (efficiency) of 500%+ that’s 9 times more than a central plant and 6 times more than a gas boiler and more than 9 times that of central plant. The savings to the end user is substantial over the lifetime of the system.
Gas Boiler
92%

A modern gas boiler has a manfacturer’s efficiency of at best 92% if well maintained over its lifespan. Boiler technology is improving slowly but will never get close to 100% as it is impossible.
Central Plant
65%

Solar PV
25%
