One of the many advantages of the classic British power circuits is that we can plug in loads of up to 3kW into a standard socket. This unit is an instant hot water unit that can be connected to a convenient cold water supply, and then plugged into a suitably located socket to offer a hot water facility without the complexity of a traditional hot water system.
These units are popular in places like construction sites and workshops.
I say "hot" water, but in reality the temperature is regulated purely by the water flow, and it often has to be quite low for a decent heat. The outlet is usually just a swivel head with a fine spray nozzle on the end, optimised to give a decent spray of water with low flow.
The safety device is usually just a silicone rubber ball that gets blown out by the water pressure if the spray nozzle clogs or gets blocked by a user. If the ball doesn't disappear down the drain it may be possible to stuff it back in carefully.
This unit is a scaled down version of the classic electric shower, which has a higher rating of 7 to 10kW for a more ample supply of hot water on demand. The huge advantage of electric showers is that the water is only heated on demand, instantly available at any time and the conversion of power to heat the water is 100% efficient.

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

This is an interesting little thing. It's a fairly common hand wash water heater as used in construction sites or workshops where you've got a cold water supply but no convenient Hot Water Systems So you can literally just put this in the wall above the sink, run a cable into it, and uh, then it. G and the cold water and it gives you hot water. So you've got the cold water in that here.
You've got the outlet here that would normally to be to a little swivel tap and you've got a pressure release thing in case something gets blocked up. It can vent the water out down to the sink, but inside. Well for a start, turn this on. when it's in use.
you basically turn this and you. It takes them all to get up to temperature, but once it's up to temperature, you can set whether it's going to be super duper hot or fairly cold. uh, very cold as it usually turns out these. but if we take the cover off the inside and I'll Zoom down this a little bit.
The inside is very reminiscent of a H Electric shower in the UK In fact, it's made by the same type of company. We' got the heater block here. We've got the tap here that diverts the water coming in across into the uh, the heater block here and then it comes out through the Um to the tap. But it also has that little safety pressure valve which if it works the same way the other ones do, it's basically a little silicon ball just pushed up so that if the output of this gets blocked instead of over pressurizing this, it will actually blow that ball out.
And it's basically to stop people trying to put TAPS in the output because this is not designed to operate at full means of water pressure. Um, in the sense that if you had a tapen output, it would pressurize the system up to that uh, full level. Also, potentially um, cause the switch the pressure switch to just basically close all the time, which wouldn't be ideal because it would bow the water inside. Uh, so the water comes in, goes through this regulator valve which just basically is a tap effectively and as well as diverting water in here, it diverts up to this switch and you've got the live com in here.
The live goes through this uh, over temperature cutout switch and then it goes over to that mic switch and then it comes back to the heat element. The neutral goes straight to the heat heat element and ultimately that's it. In here is a coiled heater Uh, fully enclosed uh in Copper and everything's well grounded here. And uh, because we have a 240 volt Supply in the UK and it's easy to Run 3 Kow from a plug that that's how this works you.
Basically you just either put it in a Spur with a cable coming in the back or a cable entrance down here with a cable grip or you can just literally plug it in a socket and that gives you the the luxury of worm water. I Wouldn't say hot water unless you had it turned down to a very low trickle. but uh, when you're on a cold instruction side, it's nice than just having you know a cold water tap to have something like this that just gives a a low spring of, uh, preheated water. There is a Rubber seal here. it's only in the top and the reason for that is just basically that's where lying water could actually drip into unit. So they've got this guard to shed over the electrics and also to try and stop it it in the first place. but there there's no seal. Round Here Although there is a port for it, but mainly because they just want to shed the water over the top and get it past the stuff and it can drip out the bottom.
I Know the Americans feel a bit comfortable about our uh, our Main's Power electric showers we have. The main advantages of them are that you get instant hot water on demand. Very efficient. There's there's no delay other than the heating of the block.
um, and it's just a super efficient way of doing it. And I will admit that in the early days of electric showers in the UK we weren't that comfortable with it either. But now we're used to them. There aren't the only accidents that have been reported.
Electrocutions and showers have been people taking the cover off and poking about inside them. The powers on uh, or just badly maintained ones. but uh, that's it. The Triton um 3 kwatt uh hand wash unit.
It's a very, very simple unit inside, but very very effective. They work really well.
If I like to heat up water, I prefer an Italian Espresso machine. 😉
Good morning from Berlin.
Commonly used in small commercial premises like charity shops etc aswel.
Seems so much easier to just wash your hands with cold water.
Just came across what I can only presume is an older video of yours on Facebook where you unpack and demonstrate a Barbie flamethrower….. I’ve been dying with laugher for half an hour
🤣3kw from a plug is a very bad idea as running close to fuse rating so Fuse gets hot after any length of time.
16 amp rcbo and a double pole switch. Just like the 3kw immersion on a plug catches fire when shielded plugs used. Been to many many that catch fire.
Dodgy as they may seem to some, not as bad as the south american electric shower head units. Some with exposed wiring from wall to shower head!
If this were made in Soviet era Russia, you wouldn't need to plug it in because the heat source would be a radioisotope. If they used polonium-210, they would only need about 22 grams to match the thermal power of your unit, but I wouldn't be surprised if they used a lot more just to deal with the drop in temperature as it decays. It has a relatively short half-life of 138 days, and large construction sites can be active for a lot longer than that, so they may prefer plutonium-238, but they would need over 5KG, which may pose a "critical" issue if too many of these units were to be stacked together. The radiation is less of an issue. This is Soviet-era Russia we're talking about, so workers exist only to be used for the benefit of the elite then discarded (apparently not much has changed).
We had this exact one in the staff room of the shop i worked in back in 2004/5. The water was absolutely BOILING that came out of it
What a luxury.
Here in germany you don't even get running water with a sink on most construction sites.
Let alone heated water
My dear Clivey,
You have dropped off recommendation by the algorithm to my feed. Fear not, it may be my wildly diverse interests.
Perhaps you should show more skin ha ha. Missed you.
So in the US typical residential is 120V 15A. 20A for kitchen, bathroom, and special application. Is it fair to assume that UK would be 7.5A /10A?
Spark school: Electricity and water don't mix!
🇬🇧:
We have a battery operated time controlled water valve for the hand sink at work, it also has an adjustment for how much hot water but it is under the sink and cover. The water pressure is weak. This would be nice because unless you stand there and activate it 3 times, the water is cold. So the water heater is useless. But if the electric goes out…
I envy countries that can do this with a normal plug. My house has an issue with the plumbing where sinks get scalding hot water while showers barely get any. We've adjusted the scald protection to little effect so my only other option was to increase the hot water temperature for the whole house so I almost burn myself while I'm washing my hands. I can't wait to get the first electric bill for that.
When kitting out my workshop, with a very low budget, I wanted hot water, but didn't want one of these ones I'd used before were only too hot or too cold (not sure why, as my Triton shower, with near identical internals is fine). I discovered Steibel Eltron's 3 phase on demand water heaters with temp control, but couldn't afford one. An eBay saved search found me a new old stock one for just £90. 21kW, which heats to 40c at normal tap flow rates. It's awesome. I didn't anticipate the SWA cable to connect it up costing far more than I'd paid for the heater though!
Does Clive on his travels just take stuff off the walls to make videos?
