I have a radiator in the living room which has not been heating up for years. I've had a couple of plumbers checked this during the years & no permanent fix for this issue. I decided to do a bit of trouble shooting & find below what I've noticed & please suggest some fix.
The only way to heat up this radiator is to release air lock by disconnecting the inlet line (hot end). When this is done the radiator will heat up but the temp will gradually drop & the heating will stop in a couple of days. There is no issue with balancing. You can turn off all other rads this one will still not heatup. There is constant build up of air in this line alone.
I thought leak might cause the issue & closed the valve in the auto fill loop. The pressure hasn't changed in a week indicating no leak in the system (or a probable back pressure). Had a chat with a plumber & he recommends a expansion tank in the hot press and gave me a quote of €140+VAT. I have a mains fed close system with auto fill.
My question: Will this fix my rad problem & is this price OK. Is there anything else to check.
