Identify shower cable

[scousespark]

I was referring to the second bit, where you wanted cable running so you could fit the showers at a later date.

As an aside, in my experience of many showers in several houses I've owned, a 10kW shower is not much better than an 8.5....people always think they're going to get a powerful, very hot shower. You won't. So maybe you're wasting your time and money upgrading....? Just my 2p.

Unless you have found a way to stop the laws of physics working a 10.8kW shower will give a flow rate almost 30% greater than an 8.5kW for the same temperature rise.

That's not insignificant.

A 30% rise in flow rate (for same temp rise) is not numerically insignificant, but perceived difference is potentially a whole different matter.

Possibly, but not inevitably, since perception can be a very strange thing. A few years back, it took me an awful lot of time/effort to dissuade my late father-in-law from having his (nearly new)10.5 kW shower changed to an 8.5 kW one - he had spent some time staying in a friend's house and felt that the (old) 8.5 kW shower there was 'much better' than his 10.5 kW one!

Kind Regards, John

Just fit a shower head with smaller holes - the exit velocity of the water will increase, you will use less water and less energy to heat it. The user perception of how good a shower is, is mainly down to the water temperature and the force with which each little jet hits the skin, not the overall volume of water supplied.

That's what the american's do with their taps isn't it.

And why it takes about 5 minutes to fill a sink over there!

I'm guessing that you are, like me, "follicly challenged".

That's what I think a good shower is.

Anyway, back to topic... I had an electrician have a look, he said remove existing showers from those 32a rcds from the main consumer unit, then for the new shower suggested a separate rcbo (I think he said rcbo, or did I get that wrong?) with at least 45a rating off to the side with a 10mm cable up to the shower via an isolator switch.

Sound ok? Or does that existing consumer unit need to go full stop?

Blimey - makes you wonder how they ever manage to sell those rain showers.

I was sure that the fact that I was seeing them more and more widely on sale, and at very premium prices, meant that they were popular and desirable and seen as a luxury item, not that the makers were desperately trying to shift them in the face of opposition to the idea that volume of water was of any value.

I'm amazed that nobody is doing a shower head with just a single tiny jet delivering water at low volume but immense force - clearly that would be the ideal.

 

[JohnW2]

The human body is not very good at directly sensing the volume of water hitting it - as has been said, what it does sense is the temperature and the velocity of the water hitting the skin - and I would add to that a sense of approximately what area of skin was being hit. From the latter two, the brain derives some perception of the volume of water involved.
"A shower head with just a single tiny jet delivering water at low volume but immense force" wouldn't work, because of the third point I added above. However, a relatively small number of tiny jets arranged in a 'divergent' pattern so that the 'hits' would cover a fairly large area of skin would probably be perceived as a much greater volume delivery than was actually the case.

You notice it when trying to remove soap from hair / body.

Not at all, quite the opposite!

I don't, and I'm about as hairy as they come! I have one of those adjustable shower heads (not the aireating type), and I find that it is less effective on full flow rate than when I close it down a little to reduce the water volume but increase the velocity.
