Focus on renewables

Putting forward an option for producing a renewable heat source in houses, David Matthews of the Ground Source Heat Pump Association explained the benefits of using a ‘Heat Pump’.

“Ground Source Heat Pumps are safe and reliable,” said David. “There is no danger of an explosion, CO poisoning or or scalds. They are good value, low carbon and run very quietly. Ground source heat pumps use pipes which are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, under-floor or warm air heating systems and hot water in a home.”

“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 the 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 – even in the middle of winter.”
