Radiator won't turn off

[Petelong7]

Hi, normally at this time of year I turn off all my rads, all have rad stats except bathroom. Have turned rad controller to 0 on boiler which normally turns off all rads. Could this be a diverter valve prob? If so, is it an easy job? Many thanks, Pete

most likely if it's a combi mate. If it's a system boiler then it's could be zone/mid position valves etc

no reason to turn ur rads off individually in the summer mate, just put the boiler into 'summer mode' when it's warm. The heating won't come on at all in this case however as you've currently got a fault you'd still get the rads warming up. Putting the boiler into summer mode saves the hassle of turning all trvs to zero.

Ps summer mode still gives you hot water
