My header tank fills with hot water when the central heating has been running for a while. It was coming out of the overflow when the heating turned off but this has know stopped. When the heating is not running the water cools.
The water is heated by a Gloworm Micron boiler. It also heats the hot water. The hot water is stored in a vented cylinder. There is no heating element connected to the cylinder. I thought i might have a faulty motorised valve but they seem to be whirring as normal. The header tank has some brown sludge in it. Could a blockage be the issue?
Would flushing the system rectify the fault?
Any guidance would be appreciated - and no i am not a copper!
