A heat pump is an electrical appliance which extracts heat from one place and moves it to another.
A fridge is like a heat pump – it uses refrigerant to extract heat from the inside to keep your food cool. A heat pump extracts heat from the outside air (air source heat pump) or a ground loop (ground source heat pump), and uses it to heat and/or cool your home. It can also be used to provide hot water.
A heat pump system operates effectively when a quality heat pump has been correctly sized for the application and there is a constant and adequate source of energy to keep it running.
Ground Source Heat Pumps
A geoexchange system collects naturally produced heat from the ground, a pond or lake through a series of plastic pipes filled with water and anti-freeze. The heat is sent to the ground source heat pump and converted into usable energy for heating, cooling and hot water. This process can be reversed if cooling is required.

Air Source Heat Pumps
In an air source heat pump, the heat produced from the outside air is used to heat water. An evaporator coil absorbs heat from the air outside. A compressor pumps refrigerant through the heat pump until the required temperature is reached. The heat exchanger then transfers the heat from the refrigerant to water, which then circulates through underfloor heating or radiators.
