Hi all, i've recently been having problems with my DHW. The problem is the boiler seems to be firing up and heating up the water but its still running cold. Although the radiators are boiling hot and their not switched on. Is it possible the water is escaping down the CH flow?
To try and eliminate this i've turned off flow and return but still water is running cold, is there anywhere else it could go?
I've checked the microswitches and the plungers, when i turn on the hot water the hot water plunger comes out ok and presses the switch, at the same time the other plunger i guess for CH comes out also and presses the switch. should this happen? any ideas on whats causing the problem.
