Hi,

I have a rather old (approx 25yrs) Thorn EMI gas boiler that just does my central heating.

I do intend to swap it for a new one next summer (obviously fitted by a CORGI contractor).

However its currently making very loud clanking and banging noises when it shuts off.

Why does it do it??????

Cheers in advance and have a great christmas!

Hi my system is the same, Does your system clang n bang more when its been running at high temp then when switched off?
I have looked up this problem before for myself and was led to believe it was gunk and rubbish floating about in the system and to flush the system out.
I have not done it yet myself so i cant tell you if its the remedy.. Sorry!
But its a start for you to look at... Good Luck! :wink:
