Electric Showers: "Kilowatt ratings explained" video from Triton Showers

Triton Electric Shower Range - www.tritonshow...
A short video explaining what a Kilowatt rating of an electric shower means in terms of the flow of water from the showerhead. The second part highlights what you need to check before upgrading your electric shower to a higher kilowatt rated unit.
Instantaneous Electric showers are still one of the most popular types of shower sold in the UK today, which is why Triton manufactures an extensive range to suit all tastes and budgets.

If you haven't already noticed, they come in a variety of different kilowatt ratings from 7.0kW up to as high as 10.5kW.
But what does this mean to you? Basically the higher the kW rating -- the higher the flow of water from your showerhead.
For example - a 7.5kW shower giving a 40-degree Celsius shower in winter will deliver a flow rate of around 3 litres per minute. That's around this much water.
By comparison, a 10.5 kW shower can give 50% more flow from the showerhead than a 7.5kW shower.
That's around this much.
If you are thinking of upgrading your shower, you will need to check out a few things before you choose a higher kW rating.
You will need to check the water pressure and flow rate, the rating of the miniature circuit breaker or fuse in your consumer unit, and the size of electric cable running to your shower.
Why?
Well, a 7kW shower, for example, is likely to need 1 bar of water pressure delivering 8 litres of water per minute to the shower.
an MCB rated at 32A
and a cable size of 6mm2
On the other hand a 10.5kW shower will need 1.5 bar water pressure delivering 11 litres per minute to the shower
an MCB rated at 45A
and a cable size of 10mm2
Therefore you may need to upgrade your shower's electrical system to support a higher kilowatt shower.

good info easy to understand I was looking for wire size for 8.5and 9.5 would have been good to see it here

man what a voice

[@gdfggggg]

It’s Triton time. You sexy bastard.

8 and 11 litres p/m at what temperature. If it is at cold water or 40 degrees C makes a shower usable or not 3L p/m is pointless.

[@eylesit9268]

Of course a 10.5kW shower delivers 50% more water when you're feeding water to it at 50% more pressure!! (1.5bar compared to 1bar)

[@tribalantidote66]

Quiet agree with you mate,i wanted to know about a 9.5 myself...

[@MarvelDcImage]

Do you sell these inside the USA? The US does have electric showers but serve as more under the counter electric heaters and look very utilitarian.

[@TritonShowers]

Unfortunately we do not offer our products in the US market. Our products are designed and intended for installation within the UK and Ireland predominantly.

cool and collective

[@eylesit9268]

Why does increasing the kW increase the need for higher input water pressure? If input water pressure is 1 bar, then wouldn't a 10.5kW shower simply apply more heat to the water than a 7kW shower, thus resulting in a higher output temperture at the same output flow rate?

Exactly

Thank you

uNFORTUNATELY THE TALKING WAS OVERPOWERED BY THE BACKING TRACK. DIFFICULT TO HEAR WHAT HE WAS SAYING. SHAME
