My central heating comes on when the timer shows it should be off. Even when I put the timer to 'off' permanently the heating still is on. I think maybe it does not go off when it should rather than come on when it shouldn't but I'm not sure. At first I thought it was the timer but it may be a sticking valve somewhere. We've only recently moved into the house so its taking a time to notice it is not working properly. Any ideas?
