How to remove old radiator permanently?

[Nikola]

There are pictures of the radiator and the TRV below. The wheel valve is off but the pipe is hot. The pipe where the TRV is is cold and it's switched off I suppose. There isn't a "0" but if I turn it all the way to the right which is "defrost" it gets really hot. So I turned it all the way to the left hand side after 1*2*3*4*5 .Can I slacken off the nut and drain It safely? I bought 2 end caps to seal the openings

if it is to be permanently removed. Yes turn boiler off, drain system down, remove valves and ideal cap off, below floor.

If the system is vented/gravity feed (eg stored water in loft tanks) then the water inlet will need isolating or water will still flow.
If system is unvented (eg combi-boiler) Then turning the water will not need to be isolated.

When refilling makes sure the system is fully vented/bled for air. Also reintroduce an inhibitor, if system water is dirty then, do a chemical clean for a couple of days, prior to draining down again and then introduce inhibitor.

Good answer, but the original Q. mentioned the rad was "in an old mental hospital" ( and in gen. diy) So I replied and suggested the plumbing forum - 2 reasons, 1 it must be a large system. 2 I am not familiar with that remote sensor/ removing it possibly getting a decorators cap, then capping the stubs to the rad. The original is still in General DIY.

Nige F, I was unaware of the original post, it does make the answer a little different as this should be carried out by a skilled person, as it could be more tricky than DIY

I am not familiar with that remote sensor/ removing it

The sensor should be easily removed, but again best done by skilled person in this case

1...If the pipes are staying,verify both valves have stopped water entering the radiator,slightly open air bleed valve until water stops. Drain radiator,Remove rad,remove rad tails fit 1/2 inch cap's http://www.ebay.co.uk/itm/BSP-STAIN...8a84379&pid=100009&rk=1&rkt=1&sd=252810905678 to rad tails and fit back into both radiator valves.
