Please help, I've been through the wiki and found some good ideas, but nothing really helps.
Problem 1 - upstairs radiators full of air.
I've bled the rads with the heating switched off, got loads of air out and the rads are now full of water again. Thought I'd cured the problem, so I switched everything back on. Now the rads upstairs or downstairs don't get even slightly warm.
We've got hot water no problems there, and the towel rail in the bathroom gets hot, this is connected to the boiler before the motorised valve so it keeps the towels nice and warm when the hot water is on.
I just can't get the rads to fire up. I'm fairly sure that my motorised valve may be at fault, but what are the symptoms to look out for?
The system is set up as follows (bear with me as I'm not a plumber);
Header tank and vent pipe in the loft, I've had my finger over the vent pipe to make sure that air isn't being sucked in when the wife was switching the system on and off. I've got a combi boiler in the kitchen on the ground floor with the pump just above. I've bled the pump also.
We've got a 5 month old baby in the house, and although the house isn't cold I really need to get to the bottom of this ASAP. I know where the location of the motorised valve is, but it involves pulling the landing floor up, so if possible I'd like to know if I can tell if it's at fault.
Many thanks in advance!
Andy.
