Just found this site for central heating prob, but this was the first message set/thread (?) I read - more entertaining than Jilly Cooper!!!!!!! Hilarious banter!
Baxi Bermuda W2. If I put the gas water heater on the tank rumbles & bubbles noisily to start, then when the :roll: water is hot the pipes or radiator upstairs (not sure which) clang as if being hit by a pan! Doesn't happen if I have hot water and heating on together! Confused!
