Thanks everyone. Appreciate all your help and expertise. The cylinder is magnetic, therefore steel, as you stated. The 'corrosion' however, appears to me to be primarily a build-up of deposits on the outside, as opposed to rust. I can chip it off with my fingernail. I can't see where the...
Thanks. Appreciate the feedback.
It has been playing on my mind what I 'signed' on his phone. He just said to keep the system all switched off in case it exploded, and when I said I wasn't sure I could do that, he said well, you'll have to sign something to say I advised you to. I didn't think...
Thanks. Why do you think it needs replacing? There is the corrosion-like area and probably a very slow leak but the brown material is on the outer surface. Looks like the grey paint is bubbling a little - (top-left of the brown part) - does that mean the whole cylinder would need to go?
Hi - wonder if someone can give me an opinion. I am undecided whether I should pay thousands for a repair, or whether I'm just being scammed.
In short - I have a solar-powered hot water system (hot solar fluid gets piped through the inside of an unvented water cylinder). When the water from the...

Thanks to everyone who took the trouble to help. I'll post back if problems resurface but for now, it's all OK.
Great forum.
Yes. I have a meter and know a reasonable amount about electrics. Not too sure of working with mains voltages, but I know the principles. Do you have an idea?
Sorry - I need to go out now, but will check back on here later/in the morning for any updates.
Many thanks once again. I don't see a second one. I've photographed the whole of the system (see below).
The last two images show the tank and the solar panel system, which I don't think are relevant to the central heating system. There is a small box on the piping from the tank (centre of...
