Good price. ordered one for replacement. Thanks

Thank god you have a decent mains water supply which allows this.
You're misunderstanding the issue. Yes, longer cable will incur more loss, but it's dissipating the heat manifested by that loss that is the problem. Your too-thin cable can overheat and the insulation can melt, however short it is.

Try using the 7.5kw that we purchased in 2012...she's a beast
Does the job though, although struggles a little in winter with temperatures nearing freezing. Perfectly adequate most of the year though.
2.5 metres from where? The consumer unit? I bet you are talking about from the 50amp double pole pull switch.
In which case your house may be liable to burn down.
Thankfully i'm not, I live in a flat so it is all really close together. Been using a 10.5Kw shower for years with no issue. My sparky friend said 10mm is good practice but with such a short length is isn't an issue.
If you do the maths it is ok just very close
What maths is this - the voltage drop in the cable or the heat dissipated per unit length? See my previous posting. Unless that cable is very well ventilated along its entire length it could melt. Besides which, if it's only 2.5m why not just replace it anyway?
Your sparky friend is a fool who is endangering your life for the sake of a few quid of decent 10mm2 cable.
Yes, you'll probably get away with it for a while if the cable is new, but the cabe WILL run hot. The insulation WILL break down a lot quicker than it should and you WILL have a problem at some point.
