Well, it gets very hot indeed if left on for an hour or two, but we
havent used it very much at all in the last 4-5 months, relying on
central heating to heat the water. I put on the immersion for a couple
of hours today to see if it would help, and there is hardly any of
that organic material coming from the taps now... much better. I
wonder why this happens though?


A bit worrying that it "gets very hot indeed"

Does anything here look familiar??
