Heat Pumps

Air Source Heat Pumps are one of the most cost-efficient heating systems today where approximately 75% of the energy needed for heating comes from ambient air in the environment.

Coefficient of Performance (COP) measures the efficiency of a heating device. The more efficient the device is, the higher the COP will be. Air Source Heat Pumps have a COP of 3.00 to 4.00 or above. This means that 3kWh to 4kWh of heating energy is produced for every 1kWh of electricity used to power the Heat Pump.

The Air Source Heat Pump works by extracting heat from ambient air and transferring it to another medium. This is done via a cycle of evaporation and condensation.


Water can easily be heated up to a temperature of 55C and the heat pumps can be integrated with conventional boiler systems to bring this water to an even higher temperature. In certain cases, specially designed heat pumps can also be used to heat water up till 80C.

Air-Sourced Heat Pumps are easily installed and can be used in a range of industries from hotels, to hospitals, student accommodation, or even spas. We also have a range that is specific for local.

How System Works


There are 4 main components to the Heat Pump:

  1. The evaporator houses the refrigerant that is maintained at a temperature lower that the outside air. This causes heat to be transferred to the refrigerant, thus causing it to evaporate.
  1. The evaporated vapour moves to the compressor and reaches a higher temperature and pressure.
  1. The heated vapour enters the condenser and transfers heat to the medium to be heated during the condensation process.
  1. The condensed refrigerant moves to the expansion valve and undergoes a drop in pressure and temperature before returning to the evaporator again.
