Geothermal. In the UK the top 10 - 15m of ground is heated by the sun and acts as a thermal store. By running pipes of water through the ground at these depths , the heat will be transferred to the water, which can then go on to heat people's homes.
What is thermal store?
Often heat networks will have a thermal store (large insulated tank of hot water). These can either provide heating temporarily if the primary source of heat fails, therefore increasing the reliability of supply for customers; or they can supply heat at a time of high demand on the fuel source to help balance out demand.
