There are two different types of Air source heating, Air to Air and Air to Water. Both are explained. If you have any questions about either, please do get in touch.

An Air to Air Heat Pump can provide heating and cooling for the home. It also features advanced air purification technology which is particularly beneficial to allergy sufferers.

The heat pump comprises an outdoor and an indoor unit which convert latent energy in the air (even on the coldest days) into heat for your home. The outdoor unit extracts the energy in air outside the property. This heat, absorbed by refrigerant solution within the unit, is turned into hot air by the indoor unit and distributed within the property.
Air source heat pumps are suitable for a wide range of installations including apartments, smaller homes and conservatories. It's operated using a remote control.

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.

• COP 4.5 The Greensource Air to Air Heat Pump has a coefficient of performance (COP) of 4.5. 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.
• Up to 500% efficient: for a single kilowatt of energy used, up to 5 kilowatts of energy could be generated for your home
• 2 year guarantee (subject to terms and conditions)
• Compact design requiring only an outside wall
• Quiet operation
• Easy to install, maintain and operate
• Works down to outdoor temperature of -20 degrees C
• Remote control displays indoor temperature
• High efficiency in all temperature ranges
• Can be used to provide cool air in the summer
• Ion-technology air purification, ideal for allergy sufferers
• Auto-defrost function
• No additional components required

Air source heat pumps are intended to be the sole source of heating and hot water production for the home.

Air to water heat pumps use the constant energy available in the air with a refrigerant circuit which allows the temperature to be boosted to a useful level for heating or hot water for the home. Greensource air to water heat pumps are Microgeneration Certification Scheme approved.
 
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.

• COP 3.7 The Greensource Air to Water Heat Pump 6kW has a coefficient of performance (COP) of 3.7. 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.
