i dont know a lot about rads, and cant make sense of how the valves
stop the water circulating the rad. how does the flow of water get to
the 'out' pipe? the vale seems to be outside the rad so i cant see how
it stops it.

anyway main question is, is it easy to remove a rad off the wall so
that i can get behind it, as it will need replastering? do i need to
stop the water supply completely and drain the system or anything?

i have a main water stop tap and this supplies a combi condensing
boiler which heats the water and central heating.


If they are hung on normal brackets and you have enough "slack" in the
pipes feeding them just slacken gently the gland nuts on the rad and lift
gently to clear the brackets then lay the rad horizontal.
Support it on something if you don't want it on the floor.

That way there's minimal disruption, no bleeding to speak of, and no
faffing around with black stains everywhere on the carpets elsewhere
Thats what I do. Lean and tie the radiator against my workmate, remove wall
fixings, plaster paint wall. attach fixings back properly (my last house had
the radiator fixings attached top the wall using a combination of 6" nails
and floorboard nails....), rehang radiator.
