Hi,
A radiator began leaking a few weeks ago so I switched it off and left it because I was going away. When I went away I switched the Central Heating off and now I'm back, it won't work, the central heating I mean. Won't fire up.
To tell the truth last night it did work - but something is amiss and I expect the problem to recur. I bled the radiators; downstairs is OK, but upstairs (where the leaky radiator was) I get a gush of air (in or out?? ) but no water. And the small tank in the loft (rather than the big one I mean) has hardly any water in it.
What could be wrong? I still haven't fitted the new radiator - plan to in a couple of days.
Any ideas?
