Ground Source Heat Pumps (GSHP)
Uses energy absorbed from the ground to heat your home.
Heat is extracted from the ground through pipes buried
in the garden, and used to heat radiators or underfloor heating systems and hot water.
Because the ground stays
at a fairly constant temperature beneath the surface, the system works efficiently all throughout the year, even in the middle
How does it work?
A mixture of water and anti-freeze is circulated
around a loop of pipe, called a ground loop, which is buried in the garden. Natural heat from the ground is absorbed
into this fluid and then pumped through a heat exchanger in the heat pump.
The heat pump compressor concentrates
the low grade heat into a higher temperature, and transfers it into heating energy and hot water. Now that the ground loop
fluid is cooler it passes back into the ground and absorbs further energy from the ground in a continuous process.
The size of your home and how much heat you use will determine the length of the ground loop.
Depending on the
size of your garden the loop is normally laid flat in trenches about one metre deep. A vertical loop may be installed
in to the ground to a depth of 100 metres if space is limited for an average domestic home.
Ground Source Heat Pumps
• Reduces your carbon footprint, heat pumps can lower your homes carbon
emissions, depending on the system being replaced
• No fuel deliveries required
• Fuel bills can be lowered
• This system needs little maintenance as it has fewer mechanical components, making it more reliable and less prone
• Systems do not create a lot of noise
