Ground Source Heat Pump

GSHPs are designed to work in cold temperatures and are incredibly efficient. Geothermal energy is a clean, renewable resource that can be harnessed for use as heat.

 

When outside temperatures are below zero, 100% of your heating and hot water needs can still be met by the Ground Source Heat Pump. This is because the ground temperature  is around 6 - 12 degrees all year round.

 

Ground source heat pumps are suitable for homes that have suitable land to install Ground Arrays or a Borehole system.

 

A Ground Array consists of a series of pipes that are installed underground in a circa 1-meter deep trench. The pipes then absorb thermal energy from the ground, which is used by the heat pump to generate heating and hot water. Ground arrays do require more room than borehole systems so are better suited for properties with ample land.

 

The Borehole systems are better suited for properties that have limited land space. Boreholes are created by drilling a hole(s) into the ground circa 120-150 meters deep to reach thermal energy deeper in the earth. The greater the depth of the borehole, the hotter the temperatures and more thermal energy can be absorbed. The depth of the hole depends on your property as the hole(s) will be sized to accommodate the heating and hot water demands the system will need to cater for.
