My central heating at the moment is turned off,the only thing I have on a timed schedule is my hot water but when my boiler kicks in to heat the hot water one of my radiators heats up and is extremely warm. Can anyone explain why this happening and is there a fix for this issue.

Some systems have a radiator attached to the circuit from the boiler to the hot water cylinder, it is usually the bathroom, this is based on the theory that you are most likely to want the bathroom warm in warmer weather when the rest of the heating is off, timers are nothing to do with it, if the hot water is on, the radiator is on, if it is not the bathroom one, it is just heat rising from the boiler, this happens occasionally if the pipework is not right, ie too close to the cylinder pipework. If it is a combination boiler, some combi's 'dump' excess heat from the hot water preheat cycle into the heating system, usually the nearest radiator to the boiler will get warm, rather than hot.

To start you did the right thing to call the technicians, second try to warm a bit of brandy and put some honey in, I don't think you have any problem with the boiler must be some connection from the boiler to the heating or/and the thermostat I have to draw them (boilers) on the plans and some times the connections, Robert C might be right as well. They will have this wee machine that would read what's the problem and will know right away. I feel so sorry for you, hope they can fix it soon as they arrive. And if not just warm a bit more of Brandy he he. Wish you all the best and give you a star for good luck. Kisses and hugs.

this happens alot every summer its the way its piped the closest connection on your return pipework to the boiler should be the return from your cylinder coil , if its not when your hot water side of things is on the return water to the cylinder finds its way into 1 or 2 rads and heats them up , if it was a valve problem all your rads would be heating . the quick fix without repiping is to fit a nonreturn valve on the return from your radiator circuit .

One radiator heats up because it is a kind of safety valve, I am guessing that you do not have a combination boiler and that your boiler heats up a tank ful of hot water? If this is the system you have then it is perfectly normal. If you have a valve on the radiator you could always turn it off.

It's supposed to, to allow hot water to circulate away from the heater when the gate valve stops it going to the tank. You'll notice that the pump will run for some time after the boiler shuts down, this is why. At least one of your rads should not have a thermostatic valve to allow this to happen. Stops your boiler blowing up.

If its like mine, I have a setting that stops the water from freezing in the radiator, so they don't turn off completely but its very very low as to feel cold to the touch. However, on one radiator the thermostat went and the radiator was warm, not a prob when it was cold but during a hot spell it was a pain in the ***. Called in a plumber and he fixed it.

there is a valve which shares the boiler output between the hot water tank and the radiators. This can leak hot to the radiators despite apparently being closed - mine did.
You can check this by turning the room thermostat up and down and watching it move. If it doesn't the motor drive is u/s as well.
You have to replace it - sorry.

I think a lot of radiator systems have one radiator that is always coming on and off, i think its to keep the system free from air bubbles. I did ask a plumber once why my radiator in the small bedroom never went off, he said it was for the above reason, and it was usually the radiator in the smallest room. Even the different places i worked had one radiator that couldnt be turned off.

Your system has a valve that shares water between the radiators and the hot water cylinder. The valve is in the wrong position - faulty, although there is a manual override on it - anybody been playing?

If this rad is in the bathroom, it is heated up when you use hot water. It was plumbed in that way. If it is anywhere else, I cannot explain this without seeing the pipework. If you don't want it on, just turn the valve off.
