Heat pumps / Underfloor heating

Air Source Heat Pumps

Air source heat pumps use outside air to heat your home or office space. This heat can then be used to heat radiators, under floor heating systems and hot water in your home.

If you imagine a fridge , but in reverse! Air source heat pumps use the same processes of refrigeration  to transfer  energy from the air outside, into higher grade energy which is then utilised for heating and domestic hot water.

A compressor is used with refrigerant within the unit to increase both its temperature and pressure.

The refrigerant is fed through a condenser where any energy is transferred to the heating system, subsequently the refrigerant is turned from a high pressured vapour into a high pressured liquid.

Passing this refrigerant  through an expansion valve  lowers its pressure and temperature.  then passing through a heat exchanger, The refrigerant will then absorb large quantities of low grade energy from the air, boiling then occurs and the liquid returns to vapour.

The continual cycle altering the liquid from vapour generates maximum extraction of energy fro the air around  your house.  


  • Reduction in utility bills
  • Not using fossil fuels, which have to be delivered
  • Provides heating and domestic hot water , especially efficient with UFH ( Under Floor Heating)
  • Should be eligible for the RHI ( Renewable Heating Incentive)
  • Could lower your home’s carbon emissions, depending on which fuel you are replacing
  • Low maintenance
