Air Source Heat Pumps (ASHPs)

Air Source Heat Pumps (ASHPs)

A heat pump is a thermodynamic machine that takes heat from outside (air or ground) a building to transfer the energy via a compressor to heat or cool a building and produce hot water. We have seen a huge increase in enquiries for ASHP’s in recent years as awareness grows and technology develops.

The ASHP only consumes the electricity required to operate the compressor and its accessories. As a result, the electrical consumption of a heat pump is 3 to 4 times lower than its energy output. There is no other system that can compete with this in terms of efficiency and running cost.

The Coefficient of Performance (COP) measures the ratio between the energy supplied and the energy used: for instance, a heat pump with a COP of 4 will consume 1 kWh of electricity and supply 4 kWh of free energy to the heating system. When combined with a solar photovoltaic system the savings are even greater!

Heat pumps offer savings of up to 70% on a heating bill and can also reduce CO2 emissions by more than 70%.


We have been very busy in recent years replacing old, inefficient gas and oil boilers with the latest technology in heat pumps. Our clients are delighted that gas or oil is no longer required and that heat pumps provide greater comfort and security along with big financial savings.


What is thermodynamism?

Thermodynamism is a closed circuit in which a refrigerant fluid in its liquid or gaseous state circulates according to the elements through which it has to flow.
