Teardown of a British electric shower that went bang.

It may sound horrific to some, but the UK commonly uses electric showers to heat the water instantly at the point of use. We do have hot water tanks or central heating systems, but it's just much more efficient to touch a button and shower under hot water in seconds.
There's a very low accident rate, with the few incidents involving very bad installations.

The one in this video is pretty old. Between 25 to 30 years old, with very retro electronics. I'm not a fan of electronics in showers at all. They just introduce reliability issues.
In this case though, the electronics were working fine right up to the end.

Time to get Ralfy my brother a new shower. (Without electronic controls.)

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
