Stainless steel hot water cylinders

[Trevor Smith]

My old vented indirect copper cylinder has started to leak around the immersion heater boss so its time for a replacement. I am thinking of going for a stainless steel one but as I live in Kent which has hard water would this be a problem with s/s, and is there any electrolytic reaction between the cylinder and the copper pipework or should I connect with short tails in hep2o.

I don't recall their being any particular warnings about electrolytic reactions with my SS cylinder. Only a requirement that a scale reduction device be used in hard water areas.
