Hi William, The system is overheating because of a faulty component, as the sensors, the pump or because of a blockage. I will check the diverter valve also as they can reduce the flow of water if the don't open fully. But don't do a powerflush specially with british gas as you can have one for around £250. Get an over check of the boiler by someone else before deciding of the powerflush. Thanks. Sevket
Hi William, Please don't allow British Gas to talk you into a power flush! They invented the power flush and charge £800.00 for a procedure that doesn't work! There may be a blockage in the pipework or radiator that's stopping the water circulating round your heating system and causing the boiler to overheat . Get a plumber to carry out a chemical flush and install a magnetic filter on the system. That will cure the problem for less than half the mine British Gas will charge for a power flush. Thanks, Vinny
