Water from a disused mine that has been warmed by the earth is to be used to heat homes in a Welsh Valleys village, the Welsh Government has said. The scheme described as “trailblazing” would use underground mine water from the workings of the old Caerau colliery, which closed in the late 1970s, to heat houses, a school and a church in Caerau in the Llynfi Valley, South Wales. On Friday, cabinet secretary for energy, planning and rural affairs Lesley Griffiths said the Welsh Government had awarded the project £6.5 million in EU funds. Bridgend County Borough Council is investigating how water in the colliery’s underground workings, which has been heated by the earth and is a geothermal source of energy, could be extracted using heat pump technology and a network of pipes to warm around 150 nearby homes. Test drilling carried out at the Old Brewers site in Caerau found the mining void is full of water to a depth of 230 metres. The results of a feasibility study to determine if the water is warm enough to heat homes is expected by the end of February. The British Geological Survey has been involved in testing the temperature, chemistry and volume of the mining water, with the temperature expected to be around 20.6 C – warm enough for the scheme to be a success.
