Ground and Air Source Heat Pumps
We supply and fit products from STIEBEL ELTRON, giving you have access to the cleanest and most crisis-proof energy supplier in the world: Mother Nature. Highly efficient systems are now capable of utilising renewables all year round. These include ground and air source heat pumps, ventilation systems with heat recovery and solar heating systems that yield energy from the environment and utilise it for DHW and central heating.
Ground Source Heat Pumps
A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, which is buried in your garden.
Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump.
The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year.
The length of the ground loop depends on the size of your home and the amount of heat you need.
Longer loops can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.
Air Source Heat Pumps
Different from a ground source heat pump, an air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside.
It can get heat from the air even when the temperature is as low as -15° C.
Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.
