Money Box takes a look at three innovative energy projects changing the way people heat their homes to try to improve efficiency and reduce bills.

First up is the village of Swaffham Prior in Cambridgeshire where residents and the local council have backed a scheme using air source and ground source heat pumps to warm people's homes. A new, multi-million pound energy centre of the edge of the village provides the energy through a newly installed heat network for any residents of the village's 300 homes that want to join.

Secondly, Dan Whitworth visits the University of Salford and the researchers behind its 'Energy House 2' project - a scheme which has seen two, modern, full-size, detached homes built by developers Barrett and Bellway inside a science laboratory. This allows scientists to create climate conditions to put the homes to the limit to test how effective they are at being energy efficient.

Finally a visit to Gateshead examines a mine water scheme being run by the council which uses the warmed water of disused, flooded coal mines to help heat council buildings and homes. More than a dozen buildings run by the council, including the local college and Sage Gateshead are signed up to the scheme as well as hundreds of homes. We'll examine how practical is it and what kind of a difference the scheme makes to people's bills.

Talking us through each of these schemes are Dr Tina Fawcett from the Environmental Change Institute at Oxford University and Ben Whittle from the Energy Saving Trust.
