Removign radiator with Thermostatic Valve

[dan1981]

Hi All,

I'm trying to remove a radiator, its one with a thermstatic valve to control the temp of the individual radiator.

The problem is the valve doesn't seem to have an "off" setting. The lowest it goes is the snowflake which i belive is a frost free setting.

Any advice?

Cheers

Normally you can unscrew the top bit from the valve and replace it with a shut off cap. This is a plastic cap with no valve which will screw down tight and shut off the valve totally.

Not sure what you do if you haven't got one though. Presumably frost setting will be enough at the moment anyway. It's not likely to get that cold just yet!

a thermo valve should have a shut off setting, unless that is, that there is a draw feed under it. Is there a little off shoot that comes out at a 45 degree angle with a squre key?

Just turn it down to the frost setting, close the valve on the other side and open the bleed screw with a towel at the ready, if both sides are closed the water from the bleed screw at the top of the rad will slow to a trickle and stop. (Rad can then be removed) If the water coming out doesn't stop/slow then you will either have to get a cap to shut it off fully or bodge something up so that the plunger in the thermostat can be "packed out" so that it pushes the pin in the valve further in when on the frost setting. A 5p coin might work. What make is the thermostat?.

What union is it? If it's 1/2", then I wouuld put a nut and olive on a bit of copper pipe and shove a Speedfit cap on it.
Don't trust the calibration of the Thermostatic head to keep it shut overnight.

Of course if you DO have a decorators cap for it then just put that on.....
