I've had an 8kw Gainsborough Sovereign for around 10 years, but I must say showering is not a very pleasant experience in these temperatures. I don't fancy re-wiring for a higher capacity unit, and I'm wondering whether replacing like with like would improve performance. We're in a medium hard water area so I imagine the innards must be well and truly caked up by now. Has anyone done this and can say, "Wow, it certainly made a difference" or something equally encouraging?
