You have helped me make a decision here,
1) to introduce an inhibitor - run the system and see the benefits/ solve the problem.
2) check out British Gas as to why they think my heat exchanger is not covered under my heating maintenance contract.
Ed,
Your point about the pump, does this help?
The temperature of the out going pipe is too hot to touch when the boiler
is set to high - whilst the return pipe remains just warm. As the house is
up to temperature and the returning water only warm - I am wondering if it
is more likely to be the pump not taking the water away from the boiler fast
enough.
I still don't understand why the noise went away for the last week and has started to return again today.
I have also challenged British Gas and am awaiting a reply.
