Description

The Greensource 7kW air to water heat pump converts latent energy in the air - even on the coldest days - into heat for your home.

The air source heat pump system comprises an outdoor and indoor unit. The outdoor unit extracts the energy in air outside the property. This energy is absorbed by a refrigerant solution which is compressed to a higher temperature. The indoor unit then uses the heat generated by the outdoor unit to create hot water for a traditional pressurised heating and hot water system.

Installation of these heat pumps is relatively simple and they are suitable for a wide range of property types.

Planning permission
Currently, your local authority must be consulted regarding planning permission for air source heat pumps. More information is available on the Energy Saving Trust’s website.

Efficiency

  • COP 3.4 The Greensource Air to Water Heat Pump 7kW has a coefficient of performance (COP) of 3.4. The CoP is a simple calculation which works out how much energy the heat pump is able to extract from the energy source compared to the amount of electrical energy used by the heat pump.
