Cold radiator
Weird I have a stone cold radiator along with the pipes that feed it.Steps to fix
1. Turned valves open on both ends
2. Checked all rads in house to make sure the return valve is open and bled rads.
3. Unable to bleed not working rad but undid the control valve sufficiently to allow water to flow and air to escape. Let it flow for a little while but didn't feel any warm water. Probably water was emptying from the radiator itself.
All other rads are nice and hot bar this one. It is like there isn't a hot water feed to it. Blasted pipes lead up to the ceiling and under the floorboards so will be a bit awkward to figure out which rad it is connected to.
Could it be lack of pressure?

Re: Cold radiator
I'm no expert MKJ but we had this last year and did all we could to try to track down the problem but, as you've said, with pipes going up into ceilings and under floorboards it's pretty daunting - so we rang a plumber.It turned out to be the valve on that rad - it was stuck in the off position, but that doesn't really apply with yours does it, although in our case the rad before the faulty one did have an air lock too, but the upstairs ones were fine!
Never got our plumber to explain that but they're all working now so sorry I can't offer more advice.
Partial pump failure perhaps? We had a pump go last year too! stevmk2

. I think I am safe in saying Spitfire has 'wumish' tendencies .Course the bleep bleep bleep heating is on
.Oh well. Will mess around a little more but looks like a plumber will have to be called eventually.
