Ground source heat pumps draw latent heat from the ground, even on cold days, and use it for heating hot water and air for use in the home. The heat pump boosts the heat from the ground to the required level and uses it to heat water or air which is then pumped around the heating system for the house.
Two systems exist for ground source heat pumps: vertical borehole or lateral underground ground loop pipes.
The vertical borehole system is used when space is limited, whereas the ground loop pipes system is used when there is more space available within the property.
However, not every home is suitable for a ground source heat pump. Ground source heat pumps are most effective in very well-insulated properties. This is because they heat water to a lower temperature than traditional boilers, meaning that many older or poorly insulated buildings are not energy efficient enough to use the underfloor heating systems or low temperature radiators for which ground source heat pumps are most effective.
The Renewable Heat Incentive (RHI) is an initiative designed to encourage investment in installations to generate renewable heat, both for domestic and non-domestic properties. When financing the installation of a ground source heat pump, the RHI aims to bridge the gap between the cost of a replacement oil or LPG boiler and the cost of a renewable heating system.
Homeowners are eligible to receive a rate of 18.3p per unit of renewable heat produced (kWh) by ground source heat pumps systems over a period of 7 years.
Rates will continue to rise according to inflation, as they are all index linked (RPI)
