I have had to remove a radiator from my central heating system while I
have my kitchen rebuilt. I will not be in a position to reconnect the
radiator for several weeks.

I need to know if I can safely run the heating with the radiator
removed?

I guess it will all depend on the type of system I have and the main
question will be whether I have to connect the two radiator pipes
together to allow the water to flow, or if I can just run the system
safely with the gap in it.

I have a Combination Boiler (a Vaillant TurboMax) and it has
(alongside pipes for gas, mains water in, hot water out) two pipes
labelled:

CHF - I assume this means Central Heating Flow
CHR - Issume this means Central Heating Return

Can anyone give me any advice on what I need to do to run the system?

Thanks

Steve

Yes, as long as the isolation valves are firmly off. Count the turns of the
lockshield valve when you turn it off, and then open it the same number when
you replace the rad. Then go to the boiler and make sure the water pressure
is 1 bar. If not, top it up via the filling loop at the boiler. Do this
when cold and do not go over 1 bar, well not by too much.

No need to link.

The 'professional' doesn't need to check whether it's single or twin
pipe...

Yes Steve, it shouldn't be a problem. Just make sure that the valves are
tight. You don't need to connect any pipes for flow.
You dont say if you have a TRV on this rad, but if you do, I would advise
capping it, as they nearly allways leak.

Should be fine. Almost all UK systems are twin pipe and don't require the
ends to be linked. Ancient systems (unlikely as you are combi) or US systems
may require linking.

It is important that you don't rely on a TRV as an isolation valve, as they
don't normally turn off fully, but go to frost protection mode, where they
can open if it gets cold overnight, emptying your system over the carpet. To
turn them off completely, you normally need a decorator's cap which holds
them fully off. (My TRVs actually have a genuine off setting half a turn
beyond the normal frost setting).

Christian.

Thanks for the replies! Jeez you guys are quick.

You couldn't tell me why I don't need to link them together could you?
Surely there will be no water flow back to the boiler if there is a gap in
the system? I'm sure there is something I don't understand.

Thanks again

Because radiators are run in parallel, not series, but you still need one
radiator open at both ends, hence if you have TRV's on the radiators, you
will find that one of them (normally bathroom) won't have one as the flow
needs to circulate back to the boiler, thus although I doubt it will apply
in your case make sure that the radiator your removing isn't the one which
recirculates the flow (if its got a TRV then your fine)

It's a flow and return system and looks a bit like this (ascii art(!)

So you can see removing one rad doesn't stop the others from working

Of course you can. All you do is drill a pair of holes in the wall and
feed a pair of extension pipes through to the outside. Simply mount the
radiator on the outside wall to maintain the balance of the system. If
it's not an outside wall, but a party wall, your neighbours will thank
you by putting gifts through your letterbox.

There is no doubt you have two left feet. Tango dancing is beyond you, so

Obviously you are not aware that n longer works. (In
fact the lack of it might be one reason for email from NTL not arriving in
certain other ISP's mailboxes. But that is another thread.) You have to go
through a multi-page web form to report anything.
