Apologies for posting as have read many similar but none identical. We have a Baxi boiler in kitchen with emersion tank bedroom and open tank in loft. Hot water is fine. A few months ago we had a nail pierce central heating pipe in bedroom, which a plumber repaired. He part drained system, which we have previous had night mares with trapped air in system. Unfortunately our brilliant and patient plumber now retired, he got to know system brilliantly. last time he eventually had to cut pipe to release air and left open pipe with shut off valve near pump which he used to release air lock.
now only 3 radiators upstairs work, none downstairs. It's freezing!
The pump was replaced 2 yrs ago seems to be working ...can feel whirling and all pipes red hot.
Some pins in trvs were depressed ...now released.
how do you work out which is the first radiator in the system when the radiators do not heat to follow to try balancing?
I have bled all radiators ... 2 upstairs had a lot of air.
really not sure what I can try next to establish if balancing problem or air lock. Any advice or help would be gratefully appreciated. Thank you
