Electric heated "suicide" shower PART 1 - teardown & calculations 

We present you the new electric heated shower head! It has 3 levels! -cold -warm - I N F E R N O

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

Oh man...! There are many accidents in Brazil... but not because of the showers but because of improper instalation

Electro Boom squad here? :))

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

It's portuguese, but with loads of grammar errors Here is the right way: Inverno - Winter 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.

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

WhyyYYYY do you taaAAALK like thiIIISS?

1:30 “bloody hell thats a lot of power”😂🤣

Great explanations on this one, looking forward to see part 2.

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....

lol he sounds like he is mocking us

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"

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.

Welcome to Brazil my dude, we use this kind of showers since the 50's (BC is more cheap than the eletric/gas heater).

I can’t wait for the testing!!!

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.

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!!!

1:18 That's not Spanish. It probably is Portuguese

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

the wall clock in the shower LOL, your videos are very interesting and educational, keep up the good work

With calculations i found your video very informative. Will keep on checking your upcoming videos.

Most people: use precise instruments and scientifically proven methods DioideGoneWild: a bucket and a russian wall clock Brilliant!

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

Omg this is terrifying. I had something similar when I was growing up in Nicaragua, crazy now that I think about it

“Part 2 - Using it” I’m sorry xD

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.

Do teď jsem si myslel, že jsem viděl už všechno:). Toto video mě přesvědčilo o opaku. Těším se na část 2.

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!

Looking forward to part 2. Part 1 was excellent.

Hello! I'm from Spain and I completely sure that's not in Spanish, it's in Portuguese

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! :)

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.

AMAZING EXPLANATION !!! we use this type of shower in my country (Bolivia) and is crazy the amount of energy they consume !

You're kind of running out of space for all these warnings, next time there will be two pages of them:-)

"bloody hell thats quite a power"

Dude, you are so smart. Great video.

Thanks for the video I am a mechanical engineer and love to do this stuff and I remind my old school days.... Thanks again

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 ?

BOOM recommended me videos by you and Clive Mitchell on this topic.

Thanks for video and calculation

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 😲

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 😁

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.

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!

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.

This thing single handedly breaks every electricians safety rules...

You are one of my favorite RU-vidrs. 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

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

A fantastic consumer protection advocate - not supported by taxes! Charming accent; no extra charge.

I really like the calculator and the clock! Dobrá práce!

Amazing video

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.

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

RU-vid recomended. it's my time to shine

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.

It's probably Portuguese because Brazil's concept of safety is even worse than China's. Thanks for your excellent demonstration of why we should use SI units.

Language is not spanish, it's portuguese. I don't think it's a suicide device. This electric shower is usual in Brazil. You need to use a 30 Ampére breaker and turn on w/ the flat switch in the first 10 seconds (for fill the chamber with water). Since the chamber is filled with water, it's not dangerous to turn on. If you follow correctly all instructions manual, there's no danger.

5000W wtf? I dont think any house wires are designed for that

i could listen to this guy all day.

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.. 😀😀 👍👍

It's portuguese. I'm from Uruguay. You can still buy them here. In the 80's I remember using them more often.

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.

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

Cold, warm, inferno. Lol. Should probably be Alive, Tingly, Tesla coil tho. This thing is terrifying

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

That big old Soviet clock used as a timer was unexpected :) Nice touch though.

Inferno🤣🤣🤣 That made me laugh for about 20minutes🤣 But actually i think the translation of this should be Inferno on this Device🤣

i just... just wanted to say ur accent is awesom XD one of a kind!

Great vid !! Stay safe please with those things.

This one is really interesting.

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.

Useful video

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

Maior medo dos Brasileiros Chamar português de espanhol

Very interesting !

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.

I thought this was gonna be a electro boom vid from the thumbnail lmao

I love that retro calculator!

wow very familiar CCCP made clock :D

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"

The math at the end is impressive

I laughed so hard when he showed the ground wire inside😂

I use this kind of shower for 32 years and never had problems. Wtf?

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.

I remember when you tried to make self-heating shower hose...somebody watched your video and decided to make a product like this one...😂

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?

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

Ayos korlll!

Gotta love Янтарь wall clock

That grounding system would trip any RCD (Residual Current Device) or RCBO (Residual Current Circuit Breaker with Over-current protection) worth its salt and thus making the device totally unusable. Variously, around the world, known as: UK: ELCB - Earth Leakage Circuit Breaker US: GFCI - (Ground Fault Circuit Interrupter GFI - Ground Fault Interrupter ALCI - Appliance Leakage Current Interrupter Aus: - RCD Safety Switch

Please don't say that water is very resistive. Extremely pure water has conductivity of around 10^-4 S/m at 25 Celcius, which is of the same order as pure silicon (a simiconductor). When exposed to main power, there will be several mA. Tape water contains lots of exterior ions and the conductivity is much higher than pure water. I have put main power into tape water and it did electrolyte water violently after few seconds (copper wire would also release copper ions when potential is applied. This would further increase the conductivity). Don't forget that warm shower water is even more conductivity.

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

@DiodeGoneWIld have you measured real power usage ?

I'm waiting for Part 2

You musta be frrrom Indiiaaa !!! Yourrr akcento is verri funyyyyy :) But goood mathematicas involved in myyyy showerrrr !! :)
