Turning off the main radiator

[heatingnoob]

Hi, I don't know much about central heating systems and I have been told never to turn off the radiator in the bathroom as it is a main radiator. The problem is that the bathroom is getting too hot and so is my bedroom as it appears the pipes run under the floor in there.

There is a coal fire that heats water for the hot taps and the central heating and there is a pump under the stairs for the heating.

Right now the pump is turned off. All of the radiators are cold except for the one in the bathroom which is very hot. I assume this is happening because the hot water rises and the cold water falls in the system so there is still a flow even without the pump.

I would like to turn this radiator off or at least down but still be able to use the heating for the downstairs radiators when required. Is this possible or must the bathroom radiator remain on?

Don't know anything about coal fire heating requirements (gasman myself), but principles are the same. Sounds like the bathroom radiator is a bypass and therefore should not be switched off. Get a qualified coal fire heating engineer to check it out and advise accordingly.

That is correct Mogg, it sounds like the bypass. So, Noob, unless you are able to install your bypass elsewhere, then you should leave it where it is
