Air Source Heat Pumps- ASHP


Air Source- How it works...

The basic principles of an air source heat pump can be explained quickly and simply:

A fan draws in outdoor air, which then passes through a heat exchanger, causing a refrigerant in the heat pump to evaporate within the heat pump circuit, this is then brought up to a higher temperature by a compressor inside, making energy available for space heating and domestic hot water heating.

Heat pumps require electricity to operate but for every unit of electricity they use, they produce upto 5 units of heat. This figure is referred to as a COP rate.

If designed correctly these systems can operate efficiently even when the outside temperature drops down to -10degC. 

Benefits of ASHP's

  • Low capital cost; one of the lowest capital costs of the Heat Pump technologies.


  • Quick turnaround; an ASHP can be installed fairly quickly, as compared to othe heat pump technologies, its relatively simple.


  • Its a green and energy efficient product, removing fossil fuel from your property.


  • Very low maintenance; ASHP systems are generally considered to have one of the lowest maintenance costs.


  • Will I be eligible for a Government Grant?


  • Do I need to change my radiators to make it work properly?


  • Do I need to service my Heat Pump?

  • Will a heat pump work with my existing electric supply?

    You may be eligible for either the Governments "Green Homes Grant" or the "RHI" and you,    may well be eligible for both. We can advise on this and assist you with any application.

    No not necessarily, some times radiators are large enough and therefore do not require

    changing, each case is different but we can advise on this.

    Yes, your heat pump must be serviced annually by a qualified proffessional and can be a stipulation of any Government grant received.

    Yes in most cases we can utilise your existing 230v supply.
