sorry, I don't understand what you mean?

I think he means a skip-grade one (provided it's not leaking).
You often find sound but aged cylinders removed where someone's up*graded
to a combi or whatever. They're OK to use if they're foam-lagged but their
heat echanger coils may not be up to current regs.

Another option with a direct cylinder might be to use it as a thermal
store with a plate heat echanger, flow switch and pump to give hot water.
It's something I've been plotting but not yet done.
