It's freezing and I've managed to stop the few that were working switching on...
Originally only two radiators in the house were working (both downstairs but another 2 downstairs weren't heating up) so I bled all the radiators and removed lots of air. Now none of the radiators are heating up - even the ones that were ok before. The (?) header tank in the attic seems to be filling and has enough water in and I'm not sure what to do next..
Any advice appreciated - I don't want to get hypothermia over the weekend!
You could have an air lock in your system. If you have a drain valve on any of the radiator valves, drain some water out of the radiator, then attach a hose to the drain valve and a cold tap, force some water into the radiator and it should force the air back into the header tank and allow the water in the system to flow again.
If you have a combi-boiler, ignore everything above and get a corgi registered plumber to look at the problem.
