Ground source heat pump: Costs, plus all questions answered

Ground source heat pumps provide a low-carbon heating solution and are likely to play a large part in decarbonising the UK's housing stock, particularly as energy prices rise and climate change heightens.

The cost of heat pump technology and how much the government will have to subsidise for them to become a realistic replacement for gas boilers have been common concerns. While the Boiler Upgrade Scheme goes some way to aid, ground source heat pumps are still a considerable investment, and are not an option for every home.

Tim is an expert in sustainable building methods and energy efficiency in residential homes and writes on the subject for magazines and national newspapers. He is the author of The Sustainable Building Bible, Simply Sustainable Homes and Anaerobic Digestion - Making Biogas - Making Energy: The Earthscan Expert Guide.

His interest in renewable energy and sustainability was first inspired by visits to the Royal Festival Hall heat pump and the Edmonton heat-from-waste projects. In 1979

this initial burst of enthusiasm lead to him trying (and failing) to build a biogas digester to convert pig manure into fuel, at a Kent oast-house, his first conversion project.

Moving in 2002 to a small-holding in South Wales, providing as it did access to a wider range of natural resources, fanned his enthusiasm for sustainability. He went on to install renewable technology at the property, including biomass boiler and wind turbine.

He formally ran energy efficiency consultancy WeatherWorks and was a speaker and expert at the Homebuilding & Renovating Shows across the country.
