Ground and Air Heating

GROUND SOURCE HEATING (GSHPs) is a central heating and/or cooling system that transfers heat to or from the ground. It uses pipes that are buried underground to extract heat from the ground, which are then used to heat radiators, underfloor or warm air heating systems and hot water in your home and uses the earth all the time, without any intermittency, as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency.

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. As the ground stays at a fairly constant temperature under the surface, the heat pump can be used throughout the year.

AIR SOURCE HEATING pumps (ASHPs), by contrast, absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home. 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.

BOTH types of 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. They both have multiple benefits, including lowering your fuel bills, especially if you replace conventional electric heating. They can lower home carbon emissions, depending on which fuel you are replacing. They will heat your home as well as your water and there is minimal maintenance required. Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods, so they are have an important role in saving energy in the domestic environment.

Heat pumps Save Energy and are an energy efficient and effective way to create hot water to heat your home or workplace. They work by absorbing heat from a source and transferring it to a liquid, which is compressed to increase the temperature further. The heat is transferred from the liquid into water which is used to provide heating for a property or Business, either through radiators or underfloor heating.

The three types of heat pumps are:

  • Air Source Heat Pumps absorb heat from the air

  • Ground Source Heat Pumps absorb heat from the ground.

  • Water Source Heat Pumps absorb heat from Water
