Air Source Technical Information

Air Source technical information

A typical Air source domestic system will be between 8-20 KW.

Air Source Heat Pumps do not need ground works so disruption is minimised, and installation costs are lower.

Air source Heat pumps can easily be fitted to walls of existing buildings.

Our Air Source Heat Pumps provide an alternative low cost solution for space heating and hot water.

Air Source Heat Pumps takes the solar energy from the outside air and raise it to a higher temperature, using a process which is similar to a reverse refrigeration process.

The outside fan draws air across the water-anti freeze solution and transfers this energy into the refrigerant. The refrigerant boils and the gases from this are compressed to produce temperatures in excess of 100°C. This part of the process mirrors a ground source heat pump.

Can be utilised all year round between +35°C and -25°C

They are noisier than Ground Source heat pumps, but our units include an innovative design which reduces noise.

Air Source heating systems must operate at lower temperatures, and should run for long periods, this makes it an excellent choice for under floor heating, but can also be used effectively for traditional heating systems.

Under floor heating is most efficient if used with hard floors such as marble or tile, it is not really suitable for wood or carpet due to their insulating properties.

For an Air Source heating system, because of the lower running temperature, you will need to include either more, larger radiators, or new enhanced efficiency radiators now available. The addition of a large designer artwork radiator to an existing system is a viable option. Alternatively, supplementary and/or a perimeter heating solution can be employed. We are happy to advise on this

It is also possible to run Air Source heating in conjunction with an existing heating system.

A standard fuel boiler may operate at flow temperatures to radiators of up to 85degrees, an Air Source heat pump would normally operate at 35 - 50 degrees. It can work at higher temperatures, but this will reduce efficiencies.

Radiators should ideally be fitted with individual thermostats.

For maximum efficiency the property should be well insulated.
