Exhaust air heat pumps (EAHP), also known as heat pump ventilation or micro heat pumps, use energy from ventilated air to heat your home and/or water. This ingenious technology reuses energy from 'waste air' in your home and can reduce your energy bills in the process. 

With air source heat pumps firmly on the radar of many homeowners looking for more efficient heating systems, you may be wondering how you can incorporate this technology into your own home?
