Heating systems designed with Ground Source Heat Pump technology are flexible and more cost effective in the long term than a traditional fossil fuel boiler. If you're currently using heating oil, LPG or electric to heat your home, you could save money on your heating bills and have greater control over your heating. Ground Source Heat Pumps have a lot in common with Air Source Heat Pumps but because of the ground works involved in the installation capital costs are higher.
- Can heat your home as well as your water
- You don’t need a Gas Supply
- The ground as a source of heat is more stable than the air because the temperature of the ground is less volitile than the air
- Low maintenance – They require very little maintenance and have a life span of well over 20 years
- Because they run at lower temperatures they are a perfect heat source for underfloor heating systems and used properly, regulate the temperature of your house more efficiently
How they work
Closed loop ground source systems use sealed pipes that are placed either horizontally or vertically in the ground. A glycol solution is pumped through the pipes, asorbing heat as it moves, this heat is then extracted by the heat pump and released at a higher temperature through compression.
Open loop ground source systems take water from aquifers or open bodies of water (ponds, rivers etc). They extract the heat, ageing through compression, and then release the cooled water back into the ground.
