Heat Pumps & Energy Efficiency

Heat Pumps are now an integral part of modern air conditioning technology but how do they work?

Providing heat when it's cold.

Because refrigerant is naturally much colder than outdoor temperatures even on a very cold day, it absorbs heat from outdoors, and transfers the heat its absorbed outside to within the building. The refrigerant's physical properties do this naturally. What you pay for is the electricity to pump refrigerant via copper tubing from outdoors to indoors. Heat pumps move the heat rather than burn fuels to create it, and as a result delivers up to 4 times the heat for the energy consumed, for example, 1kW of electricity will transfer 4kW of heat into a room.

Providing cooling when it's warm.

Come spring or summer on cooling mode, the heat pump simply reverses the process and draws heat from indoors and expels it outside. For our climate, the heat pump technology in these air conditioning units creates a far more cost effective alternative to gas or oil-fired units for heat, or a ducted air conditioning.


Heat pumps are recognised to be one of the most efficient forms of heating and cooling available. They are more efficient than some other forms of heating because heat pumps do not create heat, they just move it from one place to another. For example, the output of an efficient 10 EER* heat pump is triple that of an electric heater.

Energy efficiency has never been more important and every home and business has a need for it. All our air conditioning systems are AA rated with the latest DC inverter technology which gives you considerably increased system performance and efficiency, whilst significantly reducing running costs.

*EER (Energy Efficiency Rating) = Rated BTU capacity divided by total kW input.
