What is GeoExchange?
GeoExchange systems use a reliable and renewable energy source stored below the earth’s surface for heating, cooling and hot water. Pipes buried in the ground act as a collector, absorbing heat from the ground and moving it to a ground source heat pump located in the building.
In summer, the process is reversed with the unit delivering heat from your home back to the soil or groundwater.
Ground source heat pumps operate efficiently all year round and return up to four times more energy than they consume. They have a COP (coefficient of performance) of 4, which means that for every unit of electricity used to run the heat pump, up to 4 units of heat is produced.

Ground Source heat pumps can be used in a number of applications including:
- Residential/home heating and cooling
- Commercial heating and cooling
- Swimming Pools
- Hot Water
- Heated Towel Rails
Benefits of a Ground Source Heat Pump
GeoExchange or geothermal systems use renewable energy from the sun and do not produce gas fumes, soot or other by-products of combustion.
Long Life with Little Maintenance
The ground loop lasts for 50+ years and requires no maintenance. There are fewer mechanical components in a geothermal system and they are easier to service.
Units can be installed anywhere in your home or business and operate with minimal noise.
Clean, Safe and Reliable
The ground source heat pump is installed indoors, while the loop is underground, so they are protected from the weather and last longer.
Very Low Running Costs
A Ground Source Heat Pump is very energy efficient and can reduce heating and cooling costs by up to 70%. For every kilowatt of power supplied to the GSHP, around 4 kilowatts is generated.
Systems can be adapted for new buildings or retrofitted to suit existing buildings.
