One of my radiators is not getting hot even though the water is warm in both the inlet and outlet pipes.
Hi ,lets see if we can get you sorted in the shortest possible time. Have you removed any air that may be in the radiator with a vent key?
I have used a vent key and I thought this may have resolved the problem but didn't help.
yes it does have a honeywell thermostat which turns freely andI removed it as well to check it turns freely
Thank you for your reply can I ask you another question. when my father in law refitted the radiator after doing some decorating he had trouble turning on the outlet pipe. i checked this just now in case that wasn't open properly and the screw that locks the cap on just turns and when i took it off the bit you turn to lock off the outlet looked a little damaged. could this be the problem.
I do but I am worried I will damage it further as it looks misshapen already.
I have turned it anticlockwise and I think it is open but the rad still remains cold.
I assume that means thermostat room valve, if it does then we don't have one as all the rads in the house are thermostatic valve controlled. I have a horrible feeling after all this excellent help from you I may have to get out a plumber.
Yes it I could press it down quite freely.
No gurgling or heat
I am not able to follow the pipework. the radiator is in the back bedroom with the boiler in the top bedroom in the loft and the radiator in question is not the furthest away
