What is wrong with my dads Ideal he 30 boiler? Its an Ideal Isar HE30?
My dads boiler makes a loud groaning noise on a morning to the extent it wakes him up. It continues for some time, the only way to stop it is to run his hot tap for around 6pints of water! Any ideas? It was fitted by warmfront in december 2008.
