Ground Source Heat Pumps (GSHPs) are energy-efficient systems that use the earth's stable temperature to heat and cool buildings. They work by transferring heat from the ground into a building during winter and reversing the process in summer. This method is more sustainable than traditional heating systems, as it relies on renewable energy stored in the ground. The system consists of a series of underground pipes filled with a fluid that absorbs heat from the earth. A heat pump then compresses this heat and distributes it throughout the building. GSHPs can significantly reduce energy bills and lower carbon emissions, making them an eco-friendly choice for homeowners.
