A heat pump is a device that uses a small amount of energy to move heat from one location.   It takes heat from the air outside which is then pumped through an air exchanger which contains refrigerant-filled coils.  The air  is then  compressed,  substantially increasing the temperature thereof.  The super heated air is transferred to the water through a heat exchanger.  Excess air is released through the heat exchanger as cold air and exits through a valve.  In certain models this cold air may be utilized for air-conditioning.

What is the secret to heat pump technology?

Depending on the size of the heat pump, approximately 1KW electricity (as opposed to 2.8KW or 3.5KW on a standard geyser) is consumed and due to its excellent coefficient of performance (COP) values, it produces an output of between 3.8KW and 4.5KW.  This results in a saving of between 66% and 75% of the electricity utilized to operate a standard geyser.

Additional Benefits

Hot water can also be pumped into radiators being an excellent way of effectively heating your home.   For new building projects, our application can also be utilised for underfloor heating.  Air-conditioning recovery is also available in certain units.

Commercial Applications

Larger heat pump units and water chillers are available for commercial applications.  Where a business purchases the equipment,  the full cost of these units may be depreciated over a period of 3 years with SARS.
