Removal of a Radiator

[Apprentice]

Hi, I would like some help. A friend of mine has asked me to do a job for him which requires the removal of a radiator and to cap the pipework off at ceiling level. All there is is a hot water cylinder in the airing cupboard.

The way i see it is to firstly shut off the cold main and hot water supplies. Drain the whole system down from a drain off near to the cylinder and then remove the radiator.

Could someone give me some help and guidance please? Thank you very much

is the radiator not fitted to the flow and return of the boiler?

Maybe you are running before you walk,you do seem to have your house plumbing sections mixed up
Lots can go wrong here if not careful and expensive damage could be caused
Your friend could become a ex friend very easily
Start with smaller,more controllable jobs and work up 🙂


imho

turn boiler off
turn water off or isolate at feed and expansion cistern
drain at lowest point
cap off.

then have fun trying to get heating working again.
filling system back up turning boiler back on
getting rid of any air locks
one radiator stays cold, you have problems with that.

if it was as easy as just capping off then anyone could do it.

if your confident enough then fair enough - but like others have said it sounds like its bit out of your depth just yet.

Yes it is mate. He has a combi boiler in the kitchen and a cylinder in the airing cupboard upstairs.

i am only level 1 qualified, have been playing about my house so i don forget things i have learnt at college. When i took off the radiator, couldnt get the boiler going again, but imho you learn with your mistakes, anyway as i've got british gas insurance i can call them out as much as i want. So if i feel like plumbing i have a go, if i bodge it up give BG a ring, it soon gets sorted.

so you dont need to shut off your hot water supplies


If I was in your shoes I would ask him to get some one else or its likely your friend is going to have a non functioning boiler for a good few days

ime afraid you dont have a cylinder with a combi you do need to take a step back and give yourself a little longer before taking these jobs on

you can get this set up newbie. It could be a normal combi with an unvented cyl somewhere else in the house. Ie the cyl is heated via a zone valve off the heating circuit. I've seen it quite a few times in the posher/larger house areas. The combi feeds a zone in the house for hw and the cyl feeds the rest. It's not that uncommon bud

Ps, apologies for the argument yesterday, Hopefully we can forget about it and move on?

no prob its just something i feel strongly about but all done and dusted

op its good to get your hands on but maybe a bit of patience or ask someone to come along for guidance...

Good stuff mate.

As for the OP he clearly doesn't know what he's talking about with regards to ch and as such he should give the job to someone who does or get someone to go along and supervise him for want of a better word

hmm, any drawings of that system/basics mbear, might do one myself.

You'd have a twin channel programmer, room stat, cyl stat, hw zone valve & ch zone valve. 'Ch live out' wired into the live on the programmer Orange wires from the zone valves wired back into the 'ch live in' on the boiler all via a wiring centre obviously. Pretty much an 's plan' system on a combi mate. If you think about it it's not that bizarre and there are a few kicking about

like mbear says ive seen this set up also.

its just a case of combi supplying hot to kitchen downstairs bathroom, and unvented for main bathrooms and en suites....

good setup to be fair, kitchen always got a supply of instant water - so has downstairs loo, and ensuites are all programmed to heat up for mornings and evenings.

but i doubt the original poster has come across this system he probably more likely to of mistaken a system boiler for a combi.

have also fitted combi's to normal cylinder set up and use the hot for the shower to give good mains pressure

Advantage of using combi in this way also is that combi's are often cheaper,than higher k/w output system or open vented boilers

put an advanta system boiler in the other week and it was over £100 more than the combi equivalent,yet the combi would have had more in it,diverter valve,plate heat exchanger ect


imho
