- 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
It is so common here in Brazil and I have never heard of any case of death by electric shower head. Mine is 7800W and uses 10mm thick wiring with its own circuit breaker. Electricity here is much much cheaper than natural gas because most of our electricity energy is from water turbines, renewable and abundant

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
Pois que bosta de chineses que são malucos
@@luminumlx2604 lol e o manual é escrito em español

Provavelmente não foi erro de escrita, mas uma letra deve ter grudado na outra
You can find this in almost every home here in Brazil. The scariest part is that most electricians leave the ground wire disconnected/uninstalled either to save on wiring costs or because they're completely unaware of the purpose of that green wire. The shower works ok with only two wires, that's what they think unfortunately.
Is Brazilian. Here in Brazil has a company that produces showers, Lorenzetti, They are very good, I have one at home. They are very popular, you can find similar showers from other brands: Fame, Hydra and Sintex. This Chinese copy should try to sell to win over.
The markings in the shower are:
Invemo - Winter (It's written wrong, it's "inverno".
Desliga - Off
Verão - Summer

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.
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.
"Inferno" I laughed my ass off on that one hahaha XD. Awesome video!
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...

Brazilian Here (from south, we have 5ºC winter through June-September):
Great teardown, this shower is used in basically every house here in small Brazilian southern cities.
Some facts:
- Invemo? (it is Inverno actually) is winter
- Verão is summer
- Desliga is "Turn Off"
- I'm laughing my ass off with the term suicide shower :) it is safe, I've been using all my life.
- We plan our houses with an thick electric wire (4mm² as marked) and connect to mains voltage, without a wall connector, it is perfectly safe.
I can’t wait for the testing!!!
With calculations i found your video very informative. Will keep on checking your upcoming videos.
the wall clock in the shower LOL, your videos are very interesting and educational, keep up the good work
I got fed up with cold showers while a student in the Caribbean and went to the local hardware store....where they sold me the Suicide Shower ...It was pretty cheap and I installed it with a switched outlet in my Dorm room. I used a ritual to avoid electrocution:
1)start water flowing 2)switch on outlet and shower head. 3) Enjoy shower not touching any metal plumbing fixtures. 4) exit shower and turn off outlet switch 5) secure water supply. then switch off shower head switch. I used it for 2 years without problem....it made the water nice and warm. Thanks for the video....
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
Looking forward to part 2. Part 1 was excellent.
here in brazil, we all use this shower. For years, I never died or I was shocked. I do not know people who were shocked or died. And safe, hot and cheap
Is it grounded? Does a Brazilian wiring always have ground (earth) wire?
Some houses do, my only has ground for the shower, wich by the way is exactly this one, the rest of the house is not grounded at all, wall sockets only have 2 pins, and when we have an 3 pin connector we use these chinese adapters. This is mostly because the wiring is quite old, and it is pretty expensive to ground the house, replace wall sockets, etc. If the "grounding" can be done at all. Though like he said, I never heard of someone that died from electric shock on a shower, but I would definitely be happier if gas heating was cheaper. Btw you tought me electronics, thanks! Sorry by the english.
You do have a earth ground, its done at the pole through the neutral ac connection. Heres a tip, make sure you insert your 2 prong plugs correctly in the socket. The narrower is the positive.
its not dangerus, its not going to kill you even if you dont ground it. but it has gained the nickname "suicide shower" becaus of the ofthen poor wiring.
it won't be cheap in my country because of the electric price is quite expensive here
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!!!
Thanks for video and calculation
Thanks for the video I am a mechanical engineer and love to do this stuff and I remind my old school days.... Thanks again
AMAZING EXPLANATION !!! we use this type of shower in my country (Bolivia) and is crazy the amount of energy they consume !
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! :)
Do teď jsem si myslel, že jsem viděl už všechno:). Toto video mě přesvědčilo o opaku. Těším se na část 2.
Dude, you are so smart. Great video.
Hello! I'm from Spain and I completely sure that's not in Spanish, it's in Portuguese
The included instructions are in Spanish, but his instructions are in Hindu 😹🤪
Ok
That's not portuguese. Maybe bad spanish, but surely not portuguese.
@@RobsonWilliam82 I mean the language of the shower. "Inverno" means winter, "desliga" means turn off, and "Verão" is summer. All these words are in Portuguese. I'm 100% sure. It's not "bad Spanish" or whatever! It's clearly Portuguese!
@@fredericscriabinoff7612 Brazilian here, can confirm, it's Portuguese. These kinds of showers are quite common here.
“Part 2 - Using it”
I’m sorry xD
Unfortunatelly that was the last vid from this channel.
Omg this is terrifying. I had something similar when I was growing up in Nicaragua, crazy now that I think about it
Here we brought you some «Instantaneous hot water supply», «Iowest cost» (iowest?? 0_0) and «Protected electric shock»!
Bloody heck, I always wanted to have a protected electric shock!
You are one of my favorite TH-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
1:18 That's not Spanish. It probably is Portuguese
Yes it's Portuguese at 1:18. Voltage is 230V in Portugal
It is not portuguese from Portugal even from Brazil. Looks like spanish.
Thats correct. But "inverno" (winter) is misstyped there
AuxProx Prox Actually the package was in spanish. Brazilian protuguese looks like the european one, not spanish.
There are some words here and there that we dont share, but basically its the same language with a different accent.
AuxProx Prox The packaging looks like Spanish. However the words on the shower head are Portuguese (Spanish doesn't use the "ã").
I really like the calculator and the clock! Dobrá práce!
As always great review. Waiting for part two.
Your calculator seems to be be a very old one from the 80s .I too had one. They used a lot of batteries. Ultimately shifted to the low power LCD version in a couple of years.
Thanks :). Part 2 is coming. The calculator is Privileg 825 MD from 1975.
@PabloEscobar25 He is Czech.
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.
i could listen to this guy all day.
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.
BOOM recommended me videos by you and Clive Mitchell on this topic.
Very interesting and dangerous device. Must say I'm really looking forward to part 2 of the video!
Keep up your great work. I love your videos.
Amazing video
Je zajímavé, že tam nemají (dle ohlasů) tolik smrťáků na to, že je to zcela běžné vybavení. Jinak díky Dane za super videa.
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! 😎
Every foreigner who comes to Brazil is scared and surprised when they see an electric shower. It's not as bad as it seems. We do not use gas or oil to heat the water. We don't have boilers in our houses. What is very important for using an electric shower is the quality of the water. There is a maximum limit of permissible conductivity, which is directly associated with the quantity and diversity of dissolved minerals.
There are no cases of fires caused by electric showers. When accidents occur, they are due to installations carried out by people without any qualifications or knowledge of standards. Today, many homes have solar heating, which is much more efficient than any other form of heating and requires very little investment.
"bloody hell thats quite a power"
I love that retro calculator!
Most people: use precise instruments and scientifically proven methods
DioideGoneWild: a bucket and a russian wall clock
Brilliant!
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
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.
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.
A fantastic consumer protection advocate - not supported by taxes! Charming accent; no extra charge.
This thing single handedly breaks every electricians safety rules...
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 🤐🤐😜
TH-cam recomended.
it's my time to shine
This one is really interesting.
Yo Day I don't know how did I've started using some of his dialogues in my real life.. some other people also probably..
Faysal Khalashi , this is common. Always happens with your favorite TH-camrs. You might get his accent too. First I used to Watch GREATSCOTT too much and even today I pronounce Thing as Phing and Centimetre as Zentimeter. Now I've even started to gey DiodeGoneWild's Accent.
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
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.
wow that's great,i like the way you explain in details.if you know about two way and three way switch connections please produse the video
Useful video
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.
@DiodeGoneWIld have you measured real power usage ?
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
That big old Soviet clock used as a timer was unexpected :) Nice touch though.
5000W wtf? I dont think any house wires are designed for that
Yes, they hook those 5400W showers on their crappy wiring :). They say that the dimming lights are an indicator that the heater runs properly...
This is a stereotype, rich people also use it. The electric shower was created in Brazil because here the gas is much more expensive than the energy. Our entire gas reserve is imported from Bolivia and because of this it is a little expensive.
But why not boiler instead?
No worse than where your from Marcel, if that is your name.
yo no soy pobre (poor) , bueno, no tanto
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.
Very interesting !
Great vid !! Stay safe please with those things.
Thanks :). You can't stay safe with those things (at least not up to the 1st world standard).
We regulate flow to adjust the temperature.
Used alot in Africa coz it's cheap and one only heats the water being used...no storage issues.
Electrocution is unheard of, but fires were common (nowadays rare) if left on and the switch mechanism fail in the on position and there's no water flowing.
Tingling sensation on touching tap/gate valve if piping is metallic and one is all wet, but nowadays with ppr and pvc being widespread, even this is rare.
So, all in all, it suits those who want to save some cash.
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 ?
Hi, this sort of device is mostly used in Brazil, the writings on it are written in Portuguese. Inverno means winter and Verão mean summer.
Ten výkon bude ešte menší, lebo pri zvýšení teploty sa zvyšuje aj odpor. Takže tie merania pri izbovej teplote nie sú veľmi presné.
No každopádne tie výpočty výkonu potrebného na zohriatie vody mi nesedia, však prietokové ohrievače sa u nás bežne používajú v umývadlách a majú okolo 3kW a voda je aj tak horúca... Alebo je tam nižší tlak ako v sprche?
I love the way he talks
The math at the end is impressive
I'm waiting for Part 2
Burst into flames... huh that gives me an idea. Test that part.
Can't wait for the 2nd part.. there must be some explosion for sure. 😁😁😁
I remember that video "even more salt" 😍😍😍
No cat today but nice calculator and clock.. 😀😀 👍👍
The part two as been filmed, never uploaded for obvious reasons...
Those showerheads are only used in tropical regions where the water is already lukewarm. But I'd rather take a cold shower than using that lethal piece of heater. I don't think it's UL, CE or TÜV certified 😁
👍
I always thought that impure tap water (with its ions) is a good conductor of electricity. But in this case, it sounded like tap water has a higher resistance than the resistive coil wire. Did I get you correctly?
Aaron Koh You thought that tap water containing drinkable levels of salt / ions would be more conductive than a metal wire?
Of course not, think about it.
IncandescentWithRage
I mean yes tap water has higher resistance than the wire but the way it was explained sounded like tap water is so non-conductive that it couldn't pass dangerous level of current to the user during shower. Why wouldn't the tap water at least be considered to be connected in parallel to the resistive wire, thereby still passing high current to the user during shower?
Aaron Koh The water would be in parallel to the coil between live and neutral, and the further away ground wire in the output stream.
If the ground is connected properly, and the neutral or coil failed then it should still be "safe". Shortest route to ground is to the ground wire.
If the ground is disconnected or poor and the coil or neutral became disconnected during use, *and* the water feed is not grounded metal, the user of the shower would be the primary route to ground.
So yeah i'm sure it can kill you, but there are a few conditions to be met in combination.
Edit: That and the water will be falling on the user as droplets, not a stream.
IncandescentWithRage I agree with most of what you said. Just that I would think that the water is given two paths of electrical conduction concurrently, one is in parallel from the live to the neutral, another is from the live to the user's ground. The only reason I could think of that the user doesn't get electrocuted is that the water flows out in stream that only appears to be continuous but not really so, thereby being a discontinuous stream, it breaks the circuit from the live to the user's ground. I guess I'm wrong but that's the only reason I could think of. I'm also not sure if I interpreted your answer correctly.
Aaron Koh Yep you got it. As long as the ground is connected a tiny amount of current flows to that when working normally.
In a fault condition a larger amount of current flows to ground.
If the ground is not connected in a fault condition the user will be saved only by the stream of water breaking up as it falls. So not continuous. But touching the unit under those conditions would be very bad.
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!
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?
Can we convert this into 12v DC?
What if u put a gfci breaker on the circuit?
We don’t use copper piping in Brazil, it is only pvc, even without proper earthing the electricity don’t have a path that beside going from phase to phase, there is no continuous stream, 220v will not jump the gap
At 6:08 you can see that the terminals are right in the open. At lease they should of made a metal tube coil with the element surrounding it. At least they have a pressure switch at 7:40 so the coils don’t overheat without water.
That "Suicide shower" looks like a chinese version from Lorenzetti maxi ducha (A brazilian industry famous for do that kind of shower). That kind of shower is secure when installed in the right way, and it's very common in brazil too
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.
Yo llegué a utilizar de esos calentadores eléctricos alrededor de unos 7 y me funcionaron muy bien nada más tenía que ponerlos a tierra , estoy consciente que es peligroso por qué cuando pones las manos hasta arriba en la salida de el agua aunque estuviera a tierra daba calambres
She electrifies me.
where I can buy this
It's portuguese. I'm from Uruguay. You can still buy them here. In the 80's I remember using them more often.
Funny thing is: here in Mexico we have a very similar electrical code to the USA, because we simply copied it with minor adjustments. BUT!!! the government doesn't force you to comply with it "a priori", so the wiring in your house can be done in any way you want and the government won't say a thing... UNLESS there is a fatal accident, and if that happens then the government can charge you with a crime for not following the code. The law is reactive instead of proactive. Still, there are relatively few electrical fatalities because people don't use many high power devices, or, they know some basics to avoid accidents.
Without ELCB? It is safe?
thats amazing
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.
is heear an english version too?
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.
