Heat Pump Systems

Air Source Heat Pumps


Air source heat pumps absorb heat from the outside air so it is usually placed outside, either at the side or back of a property, and takes heat from the air, boosting it to a higher temperature using a heat pump. This heat can then be used to heat radiators, under-floor heating systems, or warm air convectors and hot water in your home. The pump needs electricity to run, but because it uses less electrical energy than the heat it produces it capitalises on the heat absorbed from the air making it a very efficent heating system.

There are a number of benefits in installing an air source heat pump. These include:

- They can generate less CO2 than conventional heating systems.

- They can provide heating and hot water.

- They require very little maintenance.

- They can be used for air conditioning in the summer.

- You need to use electricity to power the pump which circulates the liquid in the outside loop, but for every unit of electricity used by the pump, you get between two and three units of heat – making this an efficient way to heat a building.

Cheaper Economy 7 electricity tariffs can be used to lower the cost of electricity to power the heat pump and special heat pump tariffs may be available from some electricity suppliers. Alternatively, you may consider solar photovoltaic panels for a greener source of electricity.

Will I need Planning permission? Air source heat pump installations in England and Scotland may be considered Permitted Development, meaning that you will not need planning permission, but beacuse the criteria are complex it is always a good idea to check with your local planning office. If you live in Wales or Northern Ireland however, air source heat pump installations do require planning permission.

Ground Source heat pumps


"A ground source heat pump system utilizes heat from underground by pumping water through it. The pump uses pipes which are buried in the garden to extract heat from the ground. This heat can then be used to provide warmth for your home by heating radiators, under-floor or warm air heating systems, and heating water in your home."

The heat pump can be used throughout the year – even in the middle of winter, as the ground stays at a fairly constant temperature under the surface. The length of the ground loop is dependent upon the amount of heat needed and the size of your home. Longer loops can draw additional heat from the ground, although will need more space to be buried in. A vertical bore hole can be drilled if space is limited. The heat pump acts in the same way as a boiler in a central heating system but it uses ambient heat from the ground instead of burning fuel to generate heat. Although the pump does need electricity to operate, it uses less electrical energy than the heat it produces.

There are a number of benefits in installing a ground source heat pump. These include:

- They could lower your fuel bills, especially if you replace a conventional electric heating system.

- They could provide you with an income through the government’s Renewable Heat Incentive (RHI).

- They could lower your home’s carbon emissions.

- It doesn't require fuel deliveries.

- It can provide both hot water and heating to your home.

- It requires very little maintenance.
