We had a new boiler fitted a couple of months ago. First thing I did was, I bled them all, turned the heating on to make sure they were working ok and they were, but for some reason the upstairs ones aren't coming on now. Downstairs ones are fine. Anyone know what the problem could be?
(just to let you know, it's only yesterday and today we've started puttin them on properly)
Thanks

We've got instant hot water with this new one. The old tank was taken out if that's any use.

As a quick guess I would first try turning all the radiators off that are working.Water will take the easy way around the system. The problem is an air lock on the return pipe on the upstairs circuit. Hard to push / pull a bubble of air downwards. By turning the d/s rads off the pump has a chance of breaking the bubble up and moving it on.
PS works most time for me.

More than likely, you have an air lock somewhere in the pipes routed upstairs. Try bleeding the upstairs radiators whilst the system is switched on and the pump running but be careful to catch any water that emerges from the bleed point and be ready to close the bleed nipple quickly. If you can find out which is the first upstairs radiator to be piped from downstairs, start with that one first
If this does not solve the problem,
(a) check the radiator thermostats if you have them fitted. Are they all opened up?
(b) Is the upstairs system controlled by a separate thermostat which switches a motorised valve? If so, check that the thermostat is set for a higher temperature. If this still fails, listen to, and watch, the relevant motorised valve (usually placed near to the boiler). See if you can detect that it is working when the thermostat is turned up or down.
You may have to have an automatic bleed valve fitted to the pipe going upstairs if the problem persists or if it misbehaves regularly.
Best of luck.

you're saying you had the pump replaced yet do not seem to wish to have the guy that did it come decrease back and end the activity. became the pump undesirable besides? in a lot of situations, with a downstairs boiler, the upstairs radiators will artwork and not using a pump. A blockage is severe (yet truly unusual). The boiler can produce adequate capacity to ruin maximum of your abode if outfitted up in the back of a blockage then without be conscious released by a rupture so act with caution. Edit - I have considered a plumber engaged on a equipment the position the pipes had air traps in them. What he did became get a bucket, get rid of the pipe from the radiator then open the valve into the bucket. The more effective water pass receives the air out of the traps.

It sounds like the system has not been bled through properly or its a pump malfunction if upstairs is on a seperate pump,if its only been done a couple of months ago then the sensible thing to do is contact the fitter who did the boiler.

Sounds like they need bleeding again, Muffin. The air that has got into the system will work its way to the top, so you will need to release it again. Ususally in any system there is one radiator where the air gathers - once you have sussed which one that is, you can just bleed that one. A couple more bleeds should do it and give you a nice warm winter.
If you continue to have problems, get the firm back who fitted the boiler - they will have to have been Corgi registered, and should sort you out.

I lived in house that was broken up in three apartments, and I was on the top floor. There were valves on the boiler for all three levels. If you have the same, a selinoid may have to be replaced.
Or you can just try bleeding the lines again.

Call out the installer who fitted the boiler. It may just be air, it could be that he left a zone valve or similar somewhere on the system that has jammed or it could be a blockage that has lodged in the pipework somewhere (they have a habit of sticking on a bend).

you might want to set the pump speed on your boiler to maximum, try it see if it works or you might hve an airlock in the pipes,in that case you will see a bleeding nipple it should be black cap just undo it a couple of turns while your heating is running.

these are in need of balancing ,,bleeding in order starting at the furerst away from the boiler and work back to the boiler

Maybe they need bleeding again if they system has been idle for some time the air trapped in various nooks and crannies can have gradually worked it's way up tot he top of the system
