Removing a radiator without draining the system

    Hello,

    I had been intending for a while to paint one of our rooms and would need to remove the radiator. I was sure it was not a big deal to remove one radiator without needing to drain the system but my father told me no and that it was a “big messy job”. I assumed he was correct and let the job go undone.

    I decided to do the painting this week and looked up what was required to remove the radiator and there are several sources that show it is possible to remove just one without draining the system.

    My father does have plumbing experience and knowledge so wouldn’t have been just spoofing.

    Is there any reason why it couldn’t be done?

    The radiator itself is a little natty and I might just replace it rather than try to clean or paint it.

    The video shows there is a bit more to it than I knew about but essentially yes this is originally how easy I thought it should be.

    Thank you.

    Would there be any negative effect if I didn’t put a new radiator on right away and just cap the two pipes?

    Depend on the size of the radiator you are removing and the overall size of your system, you might want to save the water and put it back in the overflow tank before putting the rad back on, or topping up with inhibitor.

    A couple of months ago I painted some radiators for a friend and I have to say it was one of the most satisfying painting jobs I ever did. The difference it makes to an old shabby rad is unreal.

    No, it's just like having a radiator turned off / isolated for a period of time.

    There is a lot of rust and would be beyond my ability to salvage it I think.
