Hi,

Need some advice regarding removing a radiator which runs from a combi
boiler.

I am decorating and need to remove the radiator to decorate and that behind
it.
I thought I could close the open close valve to the radiator and the
thermostat valve, and the undo the nut to bleed that radiator only, or so I
thought.

When I tried I found the water from the boiler was draining off so I
stopped, and re filled the boiler.

Is there a way to drain this radiator only without draining the boiler?
Or do I have to drain the boiler also?

Thanx for any help

I know this is a bit of a fudge, but...
Is it possible to undo the compression connections (after turning the
valves off) on either side of the radiator enough to allow the radiator
to move slightly and then "bend" it down - tighten them up to stop
any leaks and whilst supporting the radiator, decorate behind it and then
reverse the process?

Matt.

It sounds like the TRV isn't closing completely. Some TRVs have to be turned
round beyond the 0 position (sometimes to a "*") to turn off completely.
Others are supplied with a manual "maintenance" head which you can fit after
removing the thermostatic head. This should enable it to be turned off
firmly - in cases where the normal head won't.

There isn't enough play in the pipes to do this.

The thermostat valve is a Drayton

i have 4 radiators off at the moment been off 4 weeks and no water loss
sound like a trv problem

a little tip that worked for me - i managed to get a washing machine hose
that was sat in the garage ( blue / red pipe type) to fit the thread on the
valves -on 2 out of the 4 radiators i removed cos i was bothered abouta TRv
leaking

Only if you can isolate it from the system ?

Don't forget that the boiler won''t work without sufficient CH pressure

Drayton definitely require a service adapter (different valve actuator) to
close them completely.

IIRC it just has a longer operating pin in the centre to push the valve
fully shut.

Possibly you could remove the adjustable control part (knob assembly) and
insert a spacer between it and the valve to do the same thing - but it's
years since I last looked at them so I cannot be certain.
