Ground Source Heat Pumps
Pipes are buried in the earth which contain water and anti-freeze. Depending on the space available and type of project the pipes can be 1.5m deep horizontally or to depths of 100m vertically. The liquid in the pipes absorbs the heat from the ground which is at a reasonably constant temperature of between 8ºC – 12ºC all year round. The liquid passes through the heat pump and gives up the heat gained, it returns to the pipes, repeating the cycle.
Key Benefits
- Heating costs reduces fuel bills and have lower running costs.
- Security of supply no reliance on gas and oil supplies, a free fuel.
- The environment reduces carbon dioxide emissions.
- Stable COP with horizontal or vertical collectors the heat pump’s performance is increased.
- Classified as renewable energy qualifies for the proposed Renewable Heat Incentive
