Consumers may choose to switch energy companies with news that E.On is to offer free ground source heat pump technology to some vulnerable homes.
Many households claiming certain benefits which are using coal to heat their homes will be eligible for the HeatPlant system, which works by drawing water from deep underground to heat a property cleanly and more cheaply.
Worth up to £11,500, the system has been tested in the Warwickshire village of Lighthorne Heath and will provide free hot water plumbing and central heating.
Mike Newell, low carbon manager at E.On, said: "Not only will it enable us to offer another valuable option to customers who are currently coal heated, we hope it will bring local communities together while benefiting the surrounding environment."
Although many residents of Lighthorne Heath are happy with the results of the new heating system, the Energy Saving Trust is more cautious and says that features such as home insulation should be considered ahead of ground source heat pumps.
All UK homes are to be insulated over the next years in line with new government plans.
