HI Tony, just seen your question about the radiator. I tried to bleed it and it just went 'puff. Then i fiddled with the bottom valves and something happened and it was leaking and we couldn't stop it. I had to put towels on the bathroom floor.
When the plumber came, he fixed the leak and tried to bleed the radiator but he said there was no water in it. There was an airlock so................................. and on and on and on.
It's now working and I have lovely warm towels, all the way up the ladder.
