radiator not working -

[dynaharley]

Hi there,
Wondered if anyone could give me some tips on how to assess what is wrong with my radiator - Its a double radiator with thermostatic control, am not sure which pipe feeds in the hot water but neither pipes from the floor seem to heat up and the rad is stone cold?
My heating system is a baxi boiler with a tank in the loft.
I've looked at previous threads on this web site that feature similar problems, however most state that the pipes leading up to the rad are getting hot so not been able to find the answer.
any tips would be much appreciated - am not technical in the slightest but would like to try and fix it myself before phoning for a plumber - or at least appear to know what the problem is when describing the problem to him.
many thanks Sarah

Have you let out any air from the the radiator? if any.

Are both rad valves open, these are each end?

Hi, as Andy said, check valves are open, if not open them up. Take off the thermostatic valve head and check whether the pin in the middle is stuck in, test using pliers (dont pull pin right out). It could also be that the rad is air locked or has sedement build up, try turning off all the other radiators and turn on your heating, open up the culprit radiator and if it is airlocked/lightly blocked this should clear it. It is also possible that the rads are not balanced correctly, try turning down the manual valves a little on the rads that heat up the quickest so that extra flow goes to the end of the system. Finally it could be block from sedement in which case you need to flush it out.... so,,, good luck!, Andy.

Once you've followed the splendid advice above, just ride that Harley into the loft just to check that the small tank in there has got some water in it

Before riding that Harley he could be cannoeing down the stairs.
