What is a Ground Source Heat Pump?
Ground source heat pumps (GSHPs) extract heat from the ground using pipes buried in your garden. The ground temperature stays constant at 10-15°C year-round, making GSHPs incredibly efficient even in winter.
GSHPs are 300-400% efficient, meaning for every 1 kW of electricity used, they produce 3-4 kW of heat. They're the most efficient heating technology available and can reduce your heating bills by up to 70%.
