Looking for some advice. My brothers has 3 radiators upstairs that aren't heating up but downstairs rads are all hot.
He had a plumber come fix a trv leak on one of the downstairs radiator so not sure if hes done something.
Its the old type of central heating where there is a hot water cylinder tank, a boiler, and pump separately in the cupboard and water tanks in the loft.
I believe the rads have air in them but we've opened all the bleed valves at the top of all the rads and water is coming out which seems ok. Theres also bleed nipples near the copper pipes where they go to the trv and lockshield opened them too and water is coming out of them too but rads are still cold.
Any idea what the correct way to get rid of airlock in these type of system as im not too sure. I know on combi boiler system you just opened the bleed valves on the rads (normally upstairs rads) and then top the boiler from the filling loop.
Thanks.
