Ground Source Heat Pumps (sometimes known as Geothermal Heat Pumps) are used for space heating and cooling in buildings. Ground source heat pumps take advantage of the nearly constant temperature of the Earth to heat and cool buildings. Ground source heat pumps use much less energy than conventional heating systems, since they draw heat from the ground.
Ground source heat pump systems consist of three parts: the ground heat exchanger, the heat pump unit, and the air delivery system (ductwork). Heat pumps work much like refrigerators, which make a cool place (the inside of the refrigerator) cooler by transferring heat to a relatively warm place (the surrounding room), making it warmer. We offer a range of competitive finance options that you can take advantage of so that a heat pump becomes a more viable option for your heating needs. Heat pumps simply transfer free heat (not air) from one place to another, just like your refrigerator does.


You can buy a single heat pump to heat a single area or room, a `multi-system' to heat 2, 3 or 4 areas, or a fully ducted system if you wish to heat your whole home. Many people start with a single unit, and later, when they see just how convenient and comfortable heat pumps can be, go on to buy more units for other rooms. Quiet Operation - Most heat pumps are quiet indoors, as the only sound comes from the fan.
The heat exchanger is a system of pipes called a loop, which is buried in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system, moving heat from the ground to the building's interior.
During summer it cools, and due to a reversing valve in the system, it is able to reverse the gas cycle inside the unit to create heating for winter. Then, at the click of a switch your heat pump can run in reverse, acting as an air conditioner to pump heat out of your home reducing humidity and keeping it fresh and cool in summer.


A fluid (usually water or a mixture of water and antifreeze) circulates through the pipes to absorb or relinquish heat within the ground. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger, effectively moving the heat from indoors to the ground. Fujitsu's improved fan design and `quiet mode' on many models means that you simply cannot buy a quieter heat pump anywhere. The heat removed from the indoor air during the summer can also be used to heat water, providing a free source of hot water.
