Recover and reuse ambient heat stored in the ground and air with a heat pump.
Ground source heat pumps are a viable alternative to traditional oil and electric heating solutions. They harness the natural heat that is stored in the ground - at around two metres below the surface, the temperature remains at constant at around 10 ºC throughout the year. They work most efficiently by heating properties at slightly lower temperatures than conventional heating but over longer periods of time. This still provides a good cost saving.
As a renewable heat source, heat pumps are eligible for the government funded Renewable Heat Incentive (RHI) payments. They are effective heating source for properties that are well insulated, particularly those with under floor heating.
Ground source heat pumps work by extracting ground stored heat through a network of underground pipes. Depending on the size of land available nearby, these pipes are either buried in trenches or in a bore hole.
The pipes contain a mixture of water and antifreeze. As this liquid passes around the loop, it absorbs heat from the ground, raising its temperature. When the liquid reaches the pump, a compressor then raises the temperature further. A heat exchanger utilises this heat for your central heating system or to meet hot water requirements. As the liquid cools, it returns to the pipes to complete the cycle again.
Air source heat pumps extract heat from the air outside to warm homes and buildings. An energy efficient and cost effective alternative to traditional gas, oil or electric powered heating systems, air source heating pumps even work at temperatures as low -20°c!
These heat pumps work in a similar way in which a refrigerator works, only in reverse. Heat from the air is absorbed by a fluid within the pump which then passes through a compressor, raising its temperature. The liquid then passes through a heat exchanger to either heat the water in the central heating system or provide hot water.
