Radiators feel scalding to touch, could my tank in the loft running dry have caused ?

Not sure if I'm being paranoid here or not, I've had a disastrous week with anything water related, 2 floods in 2 days and now the radiators feel scalding to touch when they have not before in 8 years.

My cold water tank in the loft ran dry last week, the valve on the ball valve had seized not letting water back into the tank once it emptied.The heating had not been used during the problem time at all only the hot water for the immersion.

Anyway have put the gas heating on today and the radiators are really burning hot to touch, they have never felt this hot before and I'm a worried now that the tank in the loft running out of water could be something to do with it.

I have an open vented system, and a potterton boiler. The wall thermostat cus off fine and if i turn the knob down on the front of the boiler when its been running for what seems an age it will cut off and come back on when I turn it back up. So that seems to be working I have it set on 4, but the front of the boiler is too hot to touch as well.

Is there something else that is the thermometer for the water going round the radiators?

The pump and the pipes in my airing cupboard as like touching a kettle and I'm worried.

I have had a dope of a plumber change the valve in the loft for me,:mad: he left me with a leaking pipe up to the water storage that came all through my ceiling, my water softer spilled 17 litres of water all over the kitchen as it regenerated. All this in two days Not a good week for me and now worrying about the heating blowing up.

Any reassurance welcome.:)

First have the radiators actually got water in them? Open the bleed valves and find out.

Yes, have gone round and the ones that has a bit of air let water out.

they will have water in if hot. if the rads are too hot to touch can only be the boiler stat not controlling temperature correctly, either faulty, set too high, or sensor phial come out of pocket,

My question was related to the indication that the F&E tank had suddenly emptied itself. On reflection it was a little ham fisted expressing it that way. I'm guessing F&E rather than CWST becaue apparently the DHW has been working fine (albeit heated by immersion). The pump will be also red hot if it's running dry. The pipes to the motorised valve(s) (if any) and the pump cylinder etc could well be red hot if there is a cold feed blockage at the usual place which has suddenly freed part of itself even partially but still presenting a major restriction to circulation. Boiler stat was an intial thought too but the OP said that the boiler shuts down when she turns the control knob down. In truth she needs a proper heating engineer give the whole thing a good run over with a ruler and I think thats the best advice we can give. The water softener problem is a distraction and quite coincidental IMHO.

Booked my B/Gas boiler service for tomorrow morning that is due. So hopefully I get a clued up chap round, who can check it all out for me.

Is there a check list of things I should perhaps ask him to check just in case he's not pro active in diagnosing?

Water softener fixed today, the chap took off a tiny filter and it had quite a few large grit particles in it, so he has replaced it for me and that's all working again now, but yes nothing to do with the heating issue, just a bad week for floods and problems!

Will update tomorrow.
