Air to water heat pumps

An Air to Water Heat Pump is a refrigerant based system, like your refrigerator at home. 

The system can absorb heat from the air, and transfer that heat via a heat exchange process to water, raising its temperature sufficiently to provide space heating to either an underfloor or radiator based system, and/or hot water. They can provide water temperatures of up to 60°C (without backup electric heater) in ambient temperatures as low as -25°C*, depending on the quality of the Heat Pump. 

They are suitable for every type of application from a small domestic to a large application.Many modern designs utilise proven inverter driven heat pump technology to deliver cost effective, low carbon heating and hot water, Mitsubishi Electric’s award winning Ecodan systems and Daikin’s cost effective Altherma range provide a simple, renewable solution that rivals traditional heating systems. 

These units are:

  • Recognised as a renewable heat technology
  • Use less energy than traditional heating methods
  • Capable of reducing running costs and CO2 emissions
  • Eligible for the Domestic Renewable Heat Incentive (domestic RHI)
  • Easy to design, install and maintain
  • Fully scalable and can work independently or in conjunction with other systems
  • Capacities from 4kW to 688kW
For every 1kW of electricity fed into a heat pump unit (i.e. the outdoor part of the heating system), you could get at least 3kW of heating energy. The overall system efficiency and energy savings will depend on the comparison with your current heating system, satisfactory system design and installation, and operational settings i.e. how you use the heating system.

From small flats to large detached houses, and from an office block to a school, Heat Pumps can offer an alternative choice to traditional heating systems. They are a reliable, sustainable heating technology and able to provide efficient space heating and hot water all year round.

Like any heating system, they work more effectively in properties with high levels of thermal efficiency. Where possible we recommend undertaking basic improvements in existing properties such as cavity wall insulation, loft insulation and double glazing, before installing a heat pump.
