Default Draining a closed central heating system

"Jay and mike 1" wrote in message

I have a Vaillant TCW Sine T3W combi-boiler connected to a closed heating
system. I have removed the radiator at the end of the system in order to
reposition it.
I am trying to drain the system via a stop valve which is located below

the
boiler (the boiler is housed in an upstairs room) but no water is coming

from
the valve when it is opened.
Can anyone offer any advice as to how I can drain the system?
Many thanks


Others have suggested how, may I suggest: why?

You say you want to reposition a rad: if you're going to solder-joint new
pipework you probably do need to drain the system, but if you're using
compression or push-fit you just want to get the water out of the parts of
the system you're working on. You could drain pipework into paint trays or
cat-litter trays or other suitable containers, or if you have a wet & dray
vac that's good for sucking away water as it comes out of pipework, even as
you're cutting it.
