    Hi,
    We have a radiator needing replaced, it is permanently on the TRV was removed 10 years ago. I'm assuming that the ends can be closed off to prevent the need for an entire drain down.

    Maybe though after 10 years I should drain it all down anyway !!!!???
    TIA

    If you close both valves the rad will not heat. It will still be full of water ,and to drain it out you would need to contain the water in a large bowl ,after loosening one of the unions ( where valve meets radiator)

    Cheers Terry- just sussed out how to close them, should be a straightforward replacement just need a 700(H) x 500(W) radiator...(straightforward, excluding the fact the missus is now on about tiling the whole place which means gutting the shower room etc as I'm not faffing about working around all the fittings...!!)

    Unless I'm missing something, there's no valve on the RH end of the rad, so you can't isolate the rad. But you still might not need to do a complete draindown (unless you want to). You can isolate all the rads on the same or higher floors (assuming they have 2 valves) and the valve in the pipe from the header tank, if there is one and it has a valve. That will minimise the volume of water you have to catch.

    There is a valve on the right hand side ,it's a type of lockshield. Removing the cap at the top reveals a screw below ,which is used to open / close the valve. Usually with a hexagonal wrench ( Allen key) ,some have a simple slot for a flat bladed screwdriver.

    Yeah the TRV was removed as they realised after building the house they needed to have a single radiator on permanently (It's got a 12kw multifuel stove so if the rads were all closed it would probably blow up the thermal store....??) But good to know I can "tune" it almost the same to restrict how hot the shower room gets and divert some of the excess to the coldest room in the house, the mancave....whose TRV is fully open anyway....

    A double skin 500 x 700 rad is a bit excessive in a room 2m x 1.2m...think these fell off the back of a lorry or were spare from another job...
