I'm in the process of doing my bathroom up & want to remove the
radiator to tile behind. Can I simply close both valves and remove
it?? I ask this because I have read before on google searches that it
may be part of the 'regulation' for the central heating. My setup
from a laymans point of view is that I have an indirect system. Cold
water tank in loft, smaller ch expansion tank next to it, a hot water
cylinder in my airing cupboard which feeds this radiator in the
bathroom. Also of note is that when I put the hot water on, this
radiator alone gets hot with it. So with this set up am I still ok,
at least for a day or two to remove it and still have heating and
being able to have hot water???

Any help from more learned personnel would be very gratefully
received,

I assume that this radiator is plumbed in parallel with the indirect coil in
the hot water cylinder, and not in series with it? [If it *is* in series,
removing - or even turning off - the radiator will stop the hot water from
working]. If in doubt, turn off - but don't remove - the rad and make sure
that water still flows through the heating coil in the cylinder.

Assuming that it *is* in parallel, you can safely remove the rad. I'm sure
you're aware that, when you turn off both valves, the rad is still full of
water - and needs to be drained (by cracking each union nut in turn with a
container** and some old towels underneath) before fully undoing the unions.
Take adequate precautions against spilling evil black staining gunge on any
carpets in the vicinity when you drain and remove the rad.

** I find that aluminium foil takeaway food containers are good, because
they can be bent to fit in awkwardly shaped spaces

Have you decided what to do with the radiator brackets? If you remove them,
and fit them back over the tiles, the rad will move out relative to the
orginal wall surface, and you may have to modify the pipework. [It might
also be difficult to get then back in exactly the same position]. If you
leave the brackets in place and tile round them, the rad will go back in the
same place - but the clearance between it and the wall will be reduced by
the thickness of the tiles. This is probably the best option unless this
will leave insufficient clearance.
