I’ve done all of that, kids are in bed now so gonna head there myself. If you could suggest something else for me to try tomorrow I will do. Hubby is off work tomorrow too, or is it a case of the plumbing being wrong way around on the new rad and I need to get my brother back out?
It was late when he finished as he came after work so I told him to go and I’d let him know if it heated up. He said airlock what would you suggest for an aggressive bleed? All radiators are cold but all other radiators are turned off at the TRV and wheel head (bathroom one without a TRV)
I’m wondering now if the flow and return were right before and does it maybe need balancing? The living room radiators are hen they eventually come on are cold at the bottom and hot at top. When we had the boiler fitted they did a Magna flush on the system
