- This is the first part of my video about the famous electric heated shower head, nicknamed a "suicide shower", produced by Lorenzetti and other makers. It looks quite dangerous, but it's widely used in Latin America and I don't hear about too many electric shock deaths caused by it. I take a look inside, explain how does it work and do some calculations regarding heating water up and tank-less heaters.

hahahahaha ='D man like CS map game ;D
Iverno = winter
@@Zekyb0y I prefer the INFERNO version.
shock XD
Electro Boom squad here? :))
Somebody hEEEEreEEH? I don't know whY-YY. XD
Yes
Yo!
Yee
Yep
Oh man...! There are many accidents in Brazil... but not because of the showers but because of improper instalation
Isso ai, é por causa da instalação mau feita e mesmo assim eu nunca vi ninguém morrer por causa de chuveiro elétrico, já o chuveiro a gás.... A argentina ta cheios de motivos do pq não usar chuveiro a gás!
Exactly shitty third world electrician fuck people up all the time!!!!!
should be illegal to protect public from unnecessary deaths
@@nguy80303 So, gas heaters should be banned?
@@eleftheriaithanatos1162 Use heaters with insulation.How many lives have been lost to this design?
Your logic is flaw to involve gas heater in discussion, they also need to meet safety standards.
It's portuguese, but with loads of grammar errors
Here is the right way:
Inverno - Winter
Desliga - OFF
Verão - Summer
Inferno - Desligado - Frio

"Inferno" I laughed my ass off on that one hahaha XD. Awesome video!
Here in Australia, the water temps can be even more extreme. In hot summer months, when you turn on the tap initially, the water coming out of the cold water tap can actually be *hotter than the hot water tap* - hot water is regulated to 60c because this is the minimum temperature to kill bacteria but it's not hot enough to scold you. The initial water out of the cold water tap will have been heated in the house piping to beyond 60c.
Everything seems extreme in Australia, especially the insects. But it's a very nice place that I wish to visit one day.
@@jamescollins6085 it’s really not that extreme but yes summer can be in certain places.
lol he sounds like he is mocking us
he also copied the video idea from bigclivedotcom

XDD
He took shower with this device
At 2:07 it says "to avoid electric shock connect earth to this appliance, and the installation should be done by qualified personnel. Read carefully the manual"
Great explanations on this one, looking forward to see part 2.
Ditto.
Welcome to Brazil my dude, we use this kind of showers since the 50's (BC is more cheap than the eletric/gas heater).
And how hot/cold is your water in winter/summer without heating?
@@unbekannter_Nutzer Winter : From 5ºC to 20ºC
Summer: From 12ºC to 30ºC
It depends of course to time/day and the exactly place in Brazil.
You guys broke or what?
@@cryo_life Broke, definitely hahah
Lots of buildings have gas-heated water, but my building, for example, doesn't. Gas heating is more expensive to implement but may bring cheaper bills. Electric is cheaper to implement but the electricity bill will be expensive. It all depends...
I have been using those since... Forever XD and yes, I live Latin América. The first one I've used it was when i was a child and it were grounded incorrectly, it gave me shocks every time i was under the water and touched the faucet to close the water. Interestingly, it only happened to me and my family never had that problem
I heard somewhere that some people are more sensitive to electricity than others
they probably had that problem too but just dont love you enough to tell you
Being younger, you'd be more sensitive.
Jamás de escuchado que alguien se haya electrocutado con una ducha de estas jamás. A menos que sean de muy mala calidad
Maybe it is a electrostatic shock
The vantages:
In the most part of the Brazil the cold winter never get 5 degrees water. In my place (center of the country) the water comes at +20°.
There's no cold water losses when you start the shower.
If you have 5 people to get a shower in sequence it's not a problem.
The houses usually have 50A connection and it is not more expensive.
By the way, I love all your videos!!!
I often get some electric shock when I use these in Latin America, but it has not been deadly yet. Moreover, no one connects the ground wire to the ground because there is usually no ground wire in the buildings.
I'd imagine with a lowish flow rate and not too cold winters it might be alright (safety aside) but the power does seem low. My electric non-suicide shower is 9.5kw and is a pretty standard thing to have here in the UK. The shower head doesn't need all that much water flow to give you a proper shower and its nice and hot through winter.... but it has a properly isolated element! :)
You're kind of running out of space for all these warnings, next time there will be two pages of them:-)
Yes :D but I can still use a smaller font...
The main issue with these is...you must mount it high enough to allow the water to break up into droplets....else you you will feel, at least a "Tingle".
Also, reaching up to move the shower head while the water is running while you are standing in the shower stall will not be too pleasant.
"safety is number one priority" actually 🤐🤐😜
I can’t wait for the testing!!!
the wall clock in the shower LOL, your videos are very interesting and educational, keep up the good work
That Earthing set up is unique, not very safe as the wire will at some stage corrode away. Also most houses have probably no Earth wire in the shower. Then making an electrical connection in a damp area, not good. Great drawing. 5.4 kW is a lot of power for those copper switch contacts. Suicide head for sure.
Anybody here waiting for a shower?? More like a shower of electrons ... tsk-tsk
Thanks I'll buy it I have depression
I use showers like that for 20 years... Well connected is no dangerous
They used to blow gas in shower rooms, now its even easier.
BOOM recommended me videos by you and Clive Mitchell on this topic.
Actually is 5kW/h, 10 minutes in the high temperature will use around 0,8 kW, each kW here cost around $ 0,15 and is actually expensive these days because we're facing a drought, our electricity is main hydropower, so to keep all running need to activate that thermoelectric plants, when it's all good with hydroelectric plants on 100% each kW costs around $ 0,10, so it's a win-win situation, cheap to buy, cheap to install and cheap to use, and it is safe!
You are one of my favorite UA-camrs. I really like the crazy products you try out and explain them very detailed. Thumbs up! I will become a Patreon supporter when I'm not an poor student anymore :D
HOW
Je zajímavé, že tam nemají (dle ohlasů) tolik smrťáků na to, že je to zcela běžné vybavení. Jinak díky Dane za super videa.
remembers me of a meme, a dude gets inside the shower and says something along the lines of: dude, i never understood why people from São paulo only took showers with sandals, nos i understand, THIS SHIT IS LIVE, even with sandals i still feel a shock, whats up with these showerheads? there's only one eletricist for the entire state ?
That is a brazilian shower, desliga is disconected, verâo is summer, inverno is winter, all is in portuguese, is very common used in low resourse homes all above brazil, but is called suicide shower because in most cases, that showers are not connected into ground, because most homes don't have ground connection
In the video the writing's is in Spanish, I'm Brazilian, this words is Spanish, but you are right about (desliga, verão and inverno) portuguese and Spanish is same in some words
We used these in Nicaragua. They were great for hot showers since hot water wasn't a thing for the most part there. The one that was in my bathroom, I think may have been faulty because if you put your hand in the stream close to the showerhead, you could get a nice little shock. Sort of like when you put your tongue on a battery type of shock. I told the lady I was renting from and she said "Oh! It's not supposed to do that!". lol
This thing single handedly breaks every electricians safety rules...
Thanks for the video I am a mechanical engineer and love to do this stuff and I remind my old school days.... Thanks again
Before watching part 2:
My impression was, that the water tube is pretty narrow, so maybe it is only 100 ml/s. I'm curious to see your findings.
A 2nd remark is about the water in summer/winter. My impression is, that the water temperature does not depend that much on the season, because it is coming from the ground, where it is pretty isolated, most of the time. I would estimate that it is about 7°C in winter and 12°C in summer, but that's just guessing and your infrastructure might vary. Considering that, it might even vary more in South America, think Copa Cabana, maybe water tanks on the roofs? At least we can conclude, that a difference of 6,5°C is something remarkable, so that people are attracted to use this device, in absence of alternatives.
Of course in South-SA, it is cold enough to get visits from penguins and in the mountains of Chile etc., it will be pretty cold, too.
However, I don't think I would like to take such a shower - the shower arm might fall to the ground, break, and say good bye to your life.
Do teď jsem si myslel, že jsem viděl už všechno:). Toto video mě přesvědčilo o opaku. Těším se na část 2.
A fantastic consumer protection advocate - not supported by taxes! Charming accent; no extra charge.
UA-cam recomended.
it's my time to shine
And I spent half of my life using these, they are EVERYWHERE in South America, (i'm from Venezuela) Those things can even melt their own wires! their are often sold with a fused manual switch for free for safer installation but I've seen catastrophic failures like the heating element not turning off after the power is cut off or the current flowing to the water (in venezuela is 110v, was not lethal but goddamn I cried the fuck out when it did hit me) I was 8 at the time
Cold, warm, inferno. Lol. Should probably be Alive, Tingly, Tesla coil tho. This thing is terrifying
Inferno🤣🤣🤣 That made me laugh for about 20minutes🤣 But actually i think the translation of this should be Inferno on this Device🤣
Yeah man this was great, my mouth hurts now from all the laughing :-D
This one is really interesting.

Can't wait for part 2... OMG 😲
I'm already working on it :). It's going to be shocking :).
DiodeGoneWild Absolutely can't wait.. dear me... p.s.. love your channel brother :-) your a legend! 😎
at 2:07 the text at the top left it's italian, it says:" Warning: To avoid the risk of electric shocks connect the ground cable to a grounding system, which it should be installed by qualified personnel. Before any installation, read the instrutions carefully"
Maior medo dos Brasileiros
Chamar português de espanhol
about wiring, in Brasil, most of the country have consumer wiring with the following characteristics:
*60 Hz
*actual 120V rms phase to ground voltage, that is nominally 127V rms, and is know by the general public as '110v'
*single phase/plit phase wiring with tn-c-s protective multiple earthing/multi-grounded neutral grounding; or in other words, each house receives three wires, two live wires, each at 120Vrms/60Hz and in reverse polarity (180º apart) and a combined neutral and earth, which is connected to an local earthing rod at the entrance of the house, and from then on is distributed as a separate neutral and a ground wire.
*generally only new homes have earthed sockets and connections, most old wiring and retrofits skip the installation of ground wires to each socket.
*general lighting uses one phase and one neutral wire with a 15A breaker and no GFIs, normally half of the house is in one 15A circuit from one phase, and the other half with other 15A circuit from the other phase wire.
*high power appliances use each a separate 30A circuit, with two phase wires (thus giving a phase to phase voltage of 240V, publicly know as '220V'), generally each shower head has its own 30A circuit, with breakers in both phases and no GFCIs and the typical absent ground wiring, but sometimes separate 220v30A circuits are found for microwave ovens, washing machines and tings like that.
Burst into flames... huh that gives me an idea. Test that part.
13:40 This kinda makes you realize just how wasteful our warm water system is, and most of the heat is not even used, it just goes straight down the drain. Do you think we could recover some of the heat energy from the waste water?
I'm guessing the 'inferno' switch is cleverly built into the wiring, likely with detection circuitry to make sure the earth is not connected so that no one standing on said earth gets hurt.
a hybrid 60kw three phase boiler is the best type of heater. It heats during night time and keeps warm during the day (it uses 200w to do it, not always) and if you run out the 60kw heater will keep your water warm. Or there is a button to quickly replenish the supply in the boiler
Super rychlozabíječ typu "To je vražda, napsala" s téměř nulovým efektem. Kolik tahle blbost stojí? Že bych to poslal Fialovi, aby to bylo alespoň k něčemu.
i have a propane pod on the go heater in my home and it uses just 1 spray paint sized propain tank per week even if i take bath every day
What the reason you pay for the circuit breaker rating?
i could listen to this guy all day.
Inverno means winter and not hell, just in case you could think the shower in this option is with fire , ha ha. Yes, a long time to trust in this technology, but the physics says the electricity prefers travels the ground wire despite your body. I think that is the reason we are alive yet here in Brasil
How does such a small thing use so much power
Most of the houses in Brazil does NOT have GFI/RCD breakers (which is called DR - "Disjuntor diferencial Residual") also does NOT have grounding wires. And DOES have the suicide shower head! HA HA HA
tha´s is in Portuguese. Inverno = winter , Verão is summer :) good video
It is not spanish, it is brazilian portuguese. Actually this shower is very common here in Brazil, if it is not the most used here.
People have probably mentioned it, but when the element heats up the resistance will get higher and then since P=V^2/R the power will drop and the temperature change will diminish consequently. So it gets worse!
is heear an english version too?
We used this same circuit... and use water pipes as ground... in Kashmir .. for heat the water...
And the variation in heating is called in Kashmir :
Double phase
And Single Phase
Nice! Really good video :). Something I'm not sure about. You say that the ground takes all of the leakage current. But if the tub drain is also connected to ground, isn't it just a parrarel connection? I don't understand how it can remove the leakage current. When you calculate current in parallel circuits it is just a higher total current draw the more circuits you put in parallel.
What if u put a gfci breaker on the circuit?
13:35
Thats why we reduce the water flow in winter.
Where are you from? Your accent is really cool. :D
The 12 guage is only to 20 amps. All you need is an open coil and the ground wire won't help to much, standing on a metal drain, electricity goes head to toe. You should only expect 500-600ml per min.
I laughed so hard when he showed the ground wire inside😂
How is this any different or safer than dropping a hair drier into a tub full of water? I want to see a GFCI connected to this and see if it trips. If it does set off the GFCI that should be all anyone needs to know in regards to buying and using these.
She electrifies me.
most house wirings are not even 4mm2 , 2,5 is the standard here but thats till 16 amps , if its really 5400watt its exceptional high for something that need to heat water.
Its spanish language ...
Inverno is hot
Desliga is off
And verao is half power
.. love your channel!
Amazing video
I love that retro calculator!
WTF? 5,4 kW in this? More than electric oven or electric iron. This plastic head shower is gonna melt.
5500 watt? That's gonna result some serious electricity bill.
I remember when you tried to make self-heating shower hose...somebody watched your video and decided to make a product like this one...😂
I think that this product is already in use in Latin America for decades...
You do not need to worry about the copper not being coated because you could well be dead long before it's an issue! Life is cheap in some parts of the world, probably not got much water anyway so no problem.
I guess they’re not big on RCDs/GFCIs in South America then?!
Without ELCB? It is safe?
I sure hope they maintain the connections properly 👀
That's called "suicide shower" only by people who don't know it and don't know much about electricity. As an electrical engineering student who used this kind of shower for his whole life, I ensure that it's 100% safe.
5 seconds at google says you are lying.
Nice video and great explanation. Won't the shower head restrict the water flow a bit? Making your ∆T bigger. I also don't shower with the water fully open so it might actually work out for me with 5,4kW. Still not buying it though lol.
Thanks :). With those, you have to turn the water at full and then slowly reduce the flow until the water comes out hot enough.
DiodeGoneWild May be interesting to see what happens if water is stopped while heater is still switched on ;-)
That shower is guaranteed to trip the RCD. And that is when it works as designed. I hate to think what it "trips" if it doesn't .....
Of course it trips the RCD. That's why it's usualy used with no RCD, with the ground disconnected (!!!) or with neutral used as ground.
How can it be 4mm2 cable for 30 amps or 5400 watts , for 4mm2 cable is maxinum 20 amps or (25 amps maybe im wrong) still crazy tho , deadly
11:15 you should teach fisics, I would watch your vids :D
I love this guys accent "YOu'reeee AbBleee to Seeee Whahyyyyy" - Brings some light to this bs invention meant to kill people.
And juicy calculator, man!
I lived in a country with these showers and never had problems, but if they are badly installed if they are very dangerous
I think is only popular in Brazil, not all South America, I live in Uruguay and I have NEVER seen one of those, kind of a dangerous thing.
decilo por ti !!!
Thanks for testing that one. I have been using those on my vacations to Bolivia. I think your water pressure is a little bit to high. They use to have a tank with water on the roof and are not connected to the same type water grid as you. For me it seems like a god system and i dont know if al of them are so simple made as yours. But they heat well but its more like warm rain taking a shower over there. i turn on full power and then i have to adjust the flow of water to get the right temperature. I am of course also skeptical to the safety, so i try to dont touch any grounded parts. If i should have one i might look for a little more expensive one. And i think i would make waterproof connections and ad a separating transformer.
Yes, the water flow has to be reduced until the water comes out hot enough. But it's 5400W, you probably have no idea how big, heavy and expensive would a suitable separating transformer be :).
DiodeGoneWild 😊Its a good point. They are huge. We use separating transformers for the heating elements in our railwaypoints in Norway and they are big. About 50 kilo i would say.
“Compatible : yes “ :)
Watch from 2:25 "Fifty four hundred WAAAAAAT" "cross sectioooooon", "working pressuuuuure", freaking hilarious way of accenting words
Water breaks down into droplets as if falls so the risk of getting a shock (even if the grounding fails) is low unless your are touching it.
Are you stupid or what? You know that heating up water some will evaporate ? Water that condense to hot air and hot air go`s up... You see the point here? Yeah its 1 year old commend but still. But i guess you boys have no windows so well there is no need to worries then unless you are using this with a close environment its very very dangerous.
So everytime you take a shower with this thing, the transformer in your area will rattle rather than hum
A shower like that is scary and dangerous that heats water through the shower head
where I can buy this
Our circuit breakers can not handle that much of a power , we have standart 16A circuit breakers , thats max. 3680 watts , so only cold water for me :D
Andrej Z. I still don't understand, you guys don't have hot water tanks? Like these:www.rona.ca/en/plumbing/water-heaters
You can have the electric version or gas version
The ground wire is smaller than live and neutral wires.Its illegal in most countries
"Inferno"
Sounds about right.
5500W is going to provide you a cold shower. In Brazil, we have showers as powerful as 8500W. Those are the only ones we use in the south, where mercury can drop to less than 10 degrees Celsius in winter
That is not Spanish is Portuguese, and yes you are right inverno means inferno for obvious burning reasons.. nice videos!!!
i just... just wanted to say ur accent is awesom XD one of a kind!
Who'd have thought the income tax man would be the one to defeat you.

I want a cool Bluetooth showerhead
When somebody uses RCD/RCBO/GFCI with the shower.
(It trips)
This will trip common sensitive RCD almost instantly. It works only in areas where RCDs are still not mandatory.
Alex Tarasov Electric conductivity of drinkable tap water in CZ is in range 20-125mS/m. It is measured as two surfaces 1m2 in 1m distance. Considering most average conductivity 40mS and considering two conductors 2cm/r=0.5mm, I am getting roughly 2.8A. Considering worst case scenario 5mS water, I am getting 0.177A. Still pretty enough to trip 30mA RCD. My calculations are pretty brief so I am really not sure about accuracy however check another video from same chanel about another dangerous Chinese heater. It is made just as 2 electrodes in water (bigger surface area, but still good example) and it takes about 800W in ordinary random tap water. Considering this, any two wires close to each other (live to gnd) in tap water must trigger 30mA without doubts.
