Ground Source Heat Pump Association


Council Members

Bean Beanland, BBH Energy Strategies Ltd

Bean Beanland Bean has an Honours Degree in Physics from Imperial College and is an Associate of the Royal College of Science. He believes that well designed ground source heat pumps are scientifically key to successful decarbonisation of heat, given that the climatic conditions in the UK are so favourable to ground source technology. Bean sits on the MCS Working Group for Heat Pumps and on the Ofgem Domestic RHI Industry Forum where installer representation is invaluable in ensuring that the burden on the renewables contractor is kept to manageable levels. Bean is keen to tackle the barriers that installers face when looking to position ground source within any property's energy scheme and so is always happy to hear of the experiences of members as they go about their business. When he is not working, by his own admission, he watches far too much rugby, supporting Bath and England and his sons at Marlborough and East Grinstead clubs.

He is Chairman of the Ground Source Heat Pump Association.

Chris Davidson, Technical Director, GeniusEnergyLab

Chris Davidson

Chris graduated in Theoretical Physics at Imperial College before spending several years within the Ford Motor Company in a variety of roles from Marketing to Business Process Engineering. In 2001 he co-founded GI Energy which grew to become the UK market leader in large scale ground source heat pump systems. As Chief Technical Officer Chris and his team took direct responsibility for over 200MW of system designs from initial feasibility to system prove out and ongoing monitoring.

Chris has been instrumental in working with the DECC to improve the Renewable Heat Incentive after launch. He has also provided training for CIBSE, Cambridge University, Oxford University and Imperial College covering topics from complex energy systems analysis to ground source heat pump system design.

Having founded GeniusEnergyLab in 2014 Chris now focuses on providing design, funding, policy and consulting advice on energy systems of all sizes.

He is Vice Chairman of the Ground Source Heat Pump Association.

After an initial career in accounts with a national brewery chain, Andrea trained as a maths teacher and was headmistress of a private school until leaving education in 2010 to concentrate on the family businesses. She became involved with the GSHPA in 2014 and has been actively involved in the promotion of the technology and the Association as chair of the Marketing Committee. With experience in finance, company law, operating a private school and three commercial organisations Andrea has brought a wide range of skills to the GSHPA as well as the drive to promote the use of heat pumps to politicians, installers and potential users. An excellent communicator, she has a no-nonsence approach to business and a proven record of achieving demanding targets.

She is Treasurer of the Ground Source Heat Pump Association.

Edward Thompson, Director, ICAX Ltd

Edward Thompson

Edward Thompson joined Mark Hewitt, an architect who has specialised in energy-efficient buildings for many years, and Andy Ford, a mechanical services engineer and founding partner of Fulcrum Consulting, who jointly developed the ideas that led to Interseasonal Heat Transfer, Thermal Banks and solar assisted ground source energy. This novel ICAX approach to harnessing ground source energy has provided innovative systems for supermarkets, schools, community centres and for maintaining roads free of ice and snow.

The current challenges for GSHPA members are to demonstrate the potential for GSHPs in District Heating, to learn how to exploit the opportunities presented by Demand Side Response – as well as to persuade BEIS to take the actions it knows it should to promote ground source energy as the key route to reducing carbon emissions from heating and cooling.

After reading science at Oxford, qualifying as a Chartered Accountant and working in finance, computing and venture capital Edward has specialised in helping young companies with new ventures.

He is a Director of the Ground Source Heat Pump Association.
