Isolator overheating

[stidge]

Hi ! Situation is this , 10mm t&e approx run 10 M , 10-10.5kw Shower, 60898 40 amp , I recently( February) replaced isolator due to overheating( neutral load side) . Installed a mid price range (45a)new one , made sure off good tight connections , but now have same problem overheating load neutral side again , any advice, do I need to refit better quality isolator or could there be a fault with shower unit? Had this numerous times and just replaced isolator as loose connections, arching are common problems! Cheers

what folk completely and utterly fail to realise is that increasing the wattage / power of an electric shower is only of benefit if the water pressure is good enough to make use of the higher rating.
otherwise its just a boiling hot dribble lol.

Oh dear,beware of doctors wearing rubber gloves,a boiling hot dribble is a classic sign of prostate trouble. lol

i'll stick to my jacuzzi bath. how the hell do you smoke a smoke and drink a JD in a bloody shower, let alone read the paper!.

Plastic ducks?

But a lower wattage shower will not give the same water temperature as a higher wattage shower for the same water flow !!
This is where higher wattage showers are better as you can have higher flow and hotter water. I have never come across a shower that gives sufficiently hot water at max water flow.

Well i defy anyone to use my 4.7KW shower unit and come out saying that the water flow wasn't strong enough and that the water wasn't hot enough. It delivers more than enough of both!! Jesus, I'd be burning the skin off my flesh with a 10.5KW unit!!

I take it you mean flow as opposed to pressure.

im fairly sure one leads to the other

Like electricity, volts are no good without amps.

thanks for the physics lesson


Not an epic fail (as you like to point out according to your signature) just confused I guess ; )

i pride myself on the fail free nature of my posts but thanks for the heads up.

your put down would have had more gravitas if it didnt take you an hour later to edit it in.

Flow does not indicate pressure or visa versa. You could have 26psi at the shower bit if the filter is partially blocked you will have insufficient flow.

I'm pleased you appreciated the physics lesson. I covered it at school so am more than pleased to help.

The fail reference was in response to your signature. You clearly like to point out other peoples fails. Every one makes mistakes and some don't like it being pointed out do they?

It took me about an hour to reply but it has taken you 16 hours to reply. Not sure what your point is other than to point out that you are slower than me : ) : ) : )

edit
did it not cross your mind that i didnt reply to your post for 16 hrs because i wasnt logged on and probably in bed ?

anyway , i can see getting the last word in is of great importance to you.
congrats.

ok ok , i can see getting the last word in is of great importance to you.

16 hours in bed ! Let me guess what you do for a living

Now you have got the last word in so I have to reply again.

Flow does not indicate pressure or visa versa.

Neither does current indicate voltage or visa versa by that argument.

In simple terms, flow/current are proportional to pressure/voltage.

Here endeth the lesson.

What is the standard or expected PSI/bar on the overall cold water system in the UK??
I remember my pressurised system in Cyprus, is set at about 3 bar (I Think) which relates to around 45 PSI...

Thank you for reiterating what I said in post 13.

i believe 2 bar is generally what is expected in a property. Thats what the wet pants reduced the house with 6 bar to.....

i'll happily check out your shower, what time is my flight? Can I go on a plane with the upstairs bit, piano and bar?

Do what I do make a western union splice get a bit of 1.5mm offcut,strip it back with your dykes then wrapped one strand around the cable,pump abit of no lox onto the cable,insert tighten down problem solved.
