Hi to all,i have a ravenheat rsf 820/20 combi boiler,the problem is after i run a bath and turn off the tap,the overheat stat kicks in and shuts off the gas valve.Also when the tap is opened again the water is very very hot.Everything works fine when the heating is on.Any ideas please. Bang Head

Could be the domestic hot water control stat, but really you need an RGI to check it out .

Thanks for reply, the stat seems to be working ok,it clicks on and off and the flame goes up and down,scratching my head at the moment.
