Having shown one of the cheaper, but less safety conscious electrically heated showers used in some other parts of the world I thought it would be fair to show the insides of a typical British electrically heated shower.
It's understandable that people might be concerned about having electrical equipment in a shower cubicle with them, particularly at 240V, but when done properly (like this unit) then the risk is very low, especially when backed up with an RCD or GFI for protection against earth/ground leakage current.
Unfortunately, many of these units are now installed by crash-trained "electrical experts" courtesy of the retarded Part P instant electrical certification scam. But let's not go there. (Financially motivated deskilling.)
This unit had lots of technical surprises. Mainly because the design has been optimised for manufacturing time and costs. But it looks good quality with a sensible modular design to allow easy servicing.
These shower units are popular in the UK because they offer near instant hot water on demand without relying on a remote hot water tank or a continuous circulation pump. The high power rating is really more suited to a higher supply voltage like 220V to 240V, so I'm not sure if they do 120V versions of these.
This video was recorded with a different device to test its audio and video functionality. I may have set the exposure a bit high.

The instant coffee makers (Keurig) use a similar heating element design,
You have lovely hands for a man of a certain age.
Never realised people would be so perplexed by an electric shower, just thought they were standard worldwide
For doing anything with water I highly recommend a silicon dog feeder mat. Cheap as around 300-400mm square with a lip around the edge.
Brilliant video quality.

I always wondered about that situation of "shower is cold after someone else just used it". Thanks for resolving that!
Show me how a house-hold boiler works; now that would be a cool video!
You all had to see my face when i saw there are cables underneath the lid of the showerhead when he opened it. And then the earth wire, its hilarious 😀
Hmm… Looking at this device with a bit of terror in my eyes I must admit, that certain inventions could only happen in the Anglosaxon world… Although the so called "flow-heaters" (not sure how they should be called properly in English) are quite common in my country in Central Europe (and in all Central Europe, by the way), they are used only for heating water for washbasins or sinks in the applications where any more advanced heating system would be economically redundant. So you can mostly see them in public restrooms… They are OK because they are not exposed to direct splashes of water – to any splashes at all, in fact. But, mounting such a device in a shower… this is the most ridiculous electrical ridiculousness I have ever seen… even more ridiculous than separate taps for boiling hot and freezingly cold water… Hope I never have to use such an invention… 😉
Thanks for the reply, No water pressure is fine, and the shower head descaled. I have taken the problem up with the makers and they insist it cannot happen, but a lot of people were complaining at the time. It was about that time that outside sources started offering the balls online. My own conclusions suggested that the structure of the ball or the housing altered with heat over time and shrank in size. There was a time that I had the showers professionally fitted but so many problems with undersized wiring and loose terminals causing terminal meltdowns. I now fit my own and have no problems.
We have two units the same, every Triton we have had just gets through its guarantee and fails. The rubber balls are for one-time use once blown out although they fit back in they soon blow out again. Also, I have had them blow out prematurely one I had replaced under guarantee the other one they would not honour the guarantee saying a surge in water inlet pressure caused it. Impossible to prove otherwise. I used to keep spares but I found a cheaper way. I changed the make, Far less hassle with the new make I am using. Keep up the good work Clive I love your voice very calming when I cannot sleep.
Could have put a towel down before the teardown
A coat or three of Urethane would protect the bench top from moisture and marring.
