Ground Source Heat Pumps Hartlepool
Need An Expert?
A Ground Source Heat Pump (GSHP), also known as a geothermal heat pump, is a heating and cooling system that uses the stable temperature of the earth beneath the surface to regulate the temperature of a building. These systems transfer heat between the ground and the building to provide heating in the winter and cooling in the summer.
Key Components:
1. Underground Loop System: Pipes (usually filled with water or a water-antifreeze mixture) are buried underground, either in a horizontal or vertical loop configuration. These pipes absorb heat from the ground or dissipate heat into the ground.
3. Reversibility: In the summer, the process can be reversed. The system extracts heat from the building and transfers it into the ground, providing cooling.
Benefits of GSHPs
Energy Efficiency
GSHPs are highly efficient and can significantly reduce heating and cooling costs compared to conventional systems.
Eco-Friendly
By using renewable geothermal energy, these systems lower greenhouse gas emissions and reduce reliance on fossil fuels.
Longevity
The underground loop system can last 50+ years, while the heat pump itself can last 20-25 years with proper maintenance.
Low Operating Costs
Once installed, ground source heat pumps have lower operational costs due to their high efficiency.
F.A.Q.
Is a ground source heat pump right for your home?
Is your garden suitable for a ground loop?
The garden doesn’t need to be particularly large, but the ground must be suitable for digging a trench or borehole and accessible to digging equipment.
There are two options for installing the ground loop: vertically or horizontally. Both require some space in your garden, and you’ll need to ensure the ground is appropriate for digging.
For vertical installation, you’ll need specialized machinery to drill a borehole, which raises installation costs. Installing the pipework horizontally is more affordable, but it requires significantly more space, making it suitable only for larger gardens.
Is your home well insulated?
Ground source heat pumps operate most efficiently when producing heat at lower temperatures than traditional boilers, so it’s important that your home is well insulated and draught-proofed to ensure the system works effectively.
If you’re in England, you may qualify for vouchers through the Green Homes Grant scheme, which can cover up to two-thirds of the cost of installing insulation.
What type of heating system will you use?
Ground source heat pumps are more efficient with underfloor or warm air heating, as they operate best at lower water temperatures. Their efficiency remains high year-round because the ground temperature stays constant at 10–13°C, unaffected by seasonal changes.
