Help Heating System!
Discussion
Hi,
I've just drained the gravity fed heating system to fit some new radiators. All went smoothly until I tried to refill the system. Tank is full but hasnt filled the radiators... Although has filled 1 of them......
Any ideas? I presumed that the feed pipe was blocked so called an emergancy plumber only to be told that gravity fed systems can take upto a few days to refil.....
Is the above really the case or did he not want to come out!
Any help would be much appreciated!
Thanks

I'm assuming you've opened the bleed valves on the other radiators?
Start with the highest radiator first.
If you've done that try manually opening the zone valve/three way valve.
Edit: to open the zone valves there is usually a metal lever on the side you can pull accross and lock in place - they usually default to the closed position which maybe stopping the water. Which radiator is filled at the moment?

Downstairs in the lounge has filled up......
Valve I presume is in the airing cupboard? I have found a little blue box in there with a label saying valve actuator on It..... Should I be doing something with that?
Yes I opened all the bleeds on the radiators but no luck....
Thanks for far!!

Sounds like the one! It should be mounted on a length of copper pipe and controls when the radiators get hot water etc. there is normally a little lever on the side you can move. If not fire the boiler/controls back up and turn your heating to full - that will definitely open it! If that works you would normally hear a gurgling sound as water rushes into the rads.
If it does work shut the boiler back down and hunt for a way to open manually - you don't want to risk firing the boiler for too long if it has no water in it!!

The other possibility is an air lock in the cold feed. For this you will need about two feet of garden hose, go into the loft and feel about in the F&E cistern to locate the cold feed outlet.hold one end of the hose over the CF outlet and the other end over the outlet of the ball valve, depress ball valve with any free appendage and see if you can dislodge the air lock.
ETA Close the bleed valves first.

I shut all the bleed points on radiator last night then opened on this morning... A fair bit of air came out so I presume it's not fully blocked??
Will backfilling have me up and running or is it a short term fix. Thinking maybe I should get a plumber out to sort.....
Thanks for the help!
