Air source heat pump systems utilise the outside air as their energy source. In fact, heat pumps are able to extract heating energy from the outside air in temperatures as low as -25°C.

Air Source Heat Pumps do not require ground works for the laying of pipes, one of the major costs for ground source heat pump systems. This factor is not a consideration with air source heat systems, which reduces the costs and installation works and time considerably. The space required to install an air source system is also very much less than other systems.

As with other systems, an air source system can provide heating and hot water.

Benefits:

• A secure, local and inexhaustible resource
• Easy to install. Minimal space requirement
• Lower fuel bills and heating running costs
• Less carbon dioxide and other greenhouse gases
• Cleaner air
• Reduction in dependence on fossil fuels

Air source heat pumps systems are the lower cost alternative to the ground source and water source heat pump systems. Where space is at a premium, the air source system is often the only option available.

The efficiency of an air source heat pump system, whilst not so effective as ground or water source, is still very attractive, offering around 3kW of heat energy for every 1kW used to run the system. The lower installation costs often makes the air source system the most viable solution to a heating and hot water solution.
