CH off but all rads hot when HW on

[Steveevans101]

Hi
This problem has just started. When the hot water comes on then all the rads (upstairs and downstairs) get hot although the CH is not on. I have a gravity fed system. Can you please help me because it is today the hottest day of the year and my radiators are hot. Phew I think I might Melt soon.

The only thing I can think of is, Do your rads have a 'twiddly' knob at the bottom left or right? Try turning these down, that usually switch the rads off.

sounds like your anti gravity valve is stuck open its just a non return valve basically that will need replacing to resolve the problem

Can only guess without more info - boiler, valves etc.
