Jack a retired engineer has already installed a cheap £80 solution for transferring the heat from his conservatory into his house which has slashed his heating bills. He thinks he can do the same for his hot water bill; he is working on prototype for cheap and easily maintained wall-mounted Solar water heating system which would only cost about £500 but could half his hot water bills... interested, well meet jack on the 20th or email him at j.daledomane@btinternet.com
