I have a combi boiler in the downstairs cloak room heats the rad in that room and the first two rads on the 15mm ring upstairs (approx 4&5m from the boiler). The next rad (approx 9m from boiler) Fed from the upstairs ring but down stairs doesn't get any heat. Neither the next (approx 8m from boiler and upstairs). The flow and return on the ring isn't exceptionally hot here either. The final rad gets heat but not a great deal.
What can be the problem?
I've bled the radiators, tried balancing checked that the TRV's aren't sticking checked the motor (trying on all speed settings) and bled the whole system by removing the bleed valve completely attaching a hose and forcing the water through the system and checked no air in the motor itself.
Any advice would be much appreciated. I'm completely stumped
