A ground source heat pump provides heat and hot water to your home by harnessing solar energy stored in the ground (or other heat sources such as the water in rivers and lakes). The heat is extracted via pipes either buried in trenches, secured to a pond mat submerged in the water, or installed vertically in boreholes.
If you are a self-builder, property renovator or a homeowner simply looking to upgrade your heating system, then ground source heat pumps are the ideal way to significantly reduce your heating bills – especially if your options are limited to LPG or oil.
Find the recommended ground source heat pump design for your self build project and establish the heat pump installation costs using our costed examples.
Costed example for water source
Do you have a pond or stream in your garden that could provide heat for a ground source heat pump?
Water is an excellent conductor of heat and therefore water source ground source heat pump systems are extremely energy efficient. See example costs
Costed example for slinkies
If you have fields or paddocks adjacent to your house, then you could use slinkies in your ground source installation.
Slinkies are the name given to coiled pipe buried in trenches at a depth of 1-2m where the ground temperature remains constant all year round See example costs
Costed example for boreholes
If your have limited exposed land or a small garden, then boreholes might be a viable option for you.
Boreholes can usually be drilled into any type of ground and are a perfect space-saving solution, as the depth of the hole(s) is varied to suit the heat requirement. See example costs
