Exhaust Air Heat Pump Installation

All-in-one air source heat pump

Exhaust air heat pump installation can reduce your carbon footprint and save you money on your energy bills. Absorbing heat from waste air as it exits the home, our exhaust air heat pump system traps and converts this into useful heat energy for domestic hot water. Able to work alongside a conventional boiler, exhaust air heat pumps provide hot water production and storage usually during the summer months. Thereby, significantly reducing your carbon footprint.

Microgeneration Certification Scheme accredited, Alternative Heating Solution are Daikin and Samsung approved installers of air heat pumps and are able to install pumps produced by other manufacturers.

Benefits of Air Heat Pump Installation Include:

  • Use of an air heat pump system can significantly reduce your energy bills as you are capturing and redirecting existing heat.
  • Generating energy using heat in waste air takes advantage of natural resources reducing reliance on fossil fuels.
  • Air heat pumps are able to extract heat from air temperatures as low as 15 degrees.
  • Unlike many of their alternatives, air heat pumps are not at risk of combustion or of emitting harmful gases. Therefore, they are safe and require far less maintenance.
  • The unit can directly replace the existing direct/indirect hot water cylinder when used in conjunction with existing conventional boilers.
  • During the non-heating season, it can be used as the sole hot water cylinder heat pump with the secondary boiler not in use at all.
  • Compatible with solar energy, the unit can work with solar thermal panels (Model-S) or with solar photovoltaics (all models).
  • Easy integration with Photovoltaic Panels is possible via a dedicated solar controller (supplied separately).
  • Air heat pumps compliment underfloor heating systems as they are both optimised to run at a lower water delivery temperature
