what the fuck why would you connect a showerhead to fucking mains

that's how they heat the water, the wires you see have exposed ends inside the showerhead and the short formed when water passes through boils a portion of it

What's sad is that much safer electric showers exist. They keep everything away from the head itself, and have a "buffer" of sorts so the water has longer to heat up

but you know what fuck that let's throw safety and comfort out the window because it's brazil and we'll probably get murdered tomorrow anyway :^)

>exposed ends inside the showerhead
That is not how it works, are you retarded?

Electric showers use something like pic related to heat the water using electrical resistance.

...

There is literally nothing wrong with that.

Usually houses in tropical climates dont have a main heater to feed the whole house because there is no need for one. So they just use electric showers.

I have a gas heated one but most here are electric as well.

>are you retarded
Clearly he is. Water isn't conductive enough for that to dissipate enough power for a tankless water heater. I installed one that required 3 240V branch circuits at I think 40A a piece. From what I gather that wasn't considered big.

The setup looks safe as long as you don't get water on the wires or grab them. People who live where electric codes haven't nerfed everything tend to be smarter about shit like that. As long as that water pipe is grounded and the heater itself isn't a complete fuck up in design you're good.

>living in constant fear of being electrocuted while taking a shower

You absolutely can heat water by passing current directly through it. But the heat output is not going to be consistent enough for a shower head (and there's also the highly obvious risk of death)

I've been using these showers my entire life and i'm still alive.

you know hot water isnt just used for showering. Its needed for washing machines and dishwashers.

Don't they only have a cold water input and heat the water up for itself for the right temperature? I think it works like that.

Yes, they do, as the temperature of the water taken in from an external sources can't be trusted to reliably be at the same temperature. It's also far cheaper to electrically heat the water in the machine instead of relying on a mechanical mixing system.

The designated shitting streets.

This is where I first learned of these things. Pleasant man with a soothing voice.

>being too dumb/poor to install one of these

Daily reminder that if you shower more than once a week you are a fucking normalfag and you don't belong here

still the worst idea for a heating water

>because it's brazil and we'll probably get murdered tomorrow anyway
kek

Maybe they cost like 10 houses over there?

enjoy your explosive gas

When I was little, we used pots on a cast iron wood-burning stove to heat water for bathing. Believe me, a heated shower head is a fucking blessing compared to that.

thats not 3rd world. thats a mcgyver.

My gf has a shower just like this one. The first time I went there I was surprised because I had no idea people actually did this with their showerheads.

I was even more scared the first time I took a shower there. Nothing has ever happened to her nor her family in the years they've been using it though. I think you guys are exaggerating a little bit.

But I do agree that they look kind of shitty and dangerous.

I live in the third world and I have never had to use anything like that. My water heater is solar powered.

but that schematic is precisely how all those 3rd world showers work.

Water actually has a pretty high resistance and if you are standing on tile or ceramic its not going to electrocute you.

they are shitty and dangerous, mostly because most "installations" dont have an earth/ground connection (which should touch the water jet/stream before it exists the shower head).
try taking a shower with the shower head centimeters away from your head, you will feel a slight tingling, and if a thunder strikes you streets power supply you might die if you are taking a shower at that precise time.
water resistance is irrelevant, mostly because you body is a better conductor than water itself, so the electron will prefer to travel through you than through the water (unless you are taking baths in salty/ocean water)
point is, installed properly with proper grounding its alright, still wouldnt take a shower during a thunder storm though

>Pure water actually has a pretty high resistance and if you are standing on tile or ceramic its not going to electrocute you.
Fixed.
But most water we encounter is far from chemically pure, which is why people get electrocuted in baths etc.

big clive
mah nigga

i'm pretty sure 1st worlders aren't all complete pussies, and those things are really bound to kill you in an horrific way, but everybody use that over here since like forever and i've never even hear of people being electrocuted with those things ever.

just my biased, anecdotal evidence, but yet.

oh boy

You would need a ton of water and run it for a few days to get even a liter of helium.

Are 'muricunts really that stupid?

Keep laughing, ignorant Americunt. Houses here cost way more than in the US.

cool. it has whatsapp. and that battery must last like a month.

also, you shouldn't worry for being stabbed by a mugger anymore

There's a loose ground just before the water exits the showerhead for safety. And most newer houses include a DR that cuts power whenever it detects there's significant current leak.

Still more advanced than street shitting indians. They dont even bother with the hole or Tp. They just drop trow, squat, and then continue on their marry way.

Even if there was a perfect connection to the pipe, there would have to be a steady, unbroken stream for current to pass through the water. And even on that situation there would be a monumental amount of losses back to ground.
Im not saying its impossible or that i would use that horror show, but it is very, very unlikely youd bet even a mild shock from it.

ironically, that's a great example of what technology really is.

>the application of knowledge for practical ends
>the creation and use of technical means for social groups to provide themselves, and their interrelation with life, society, and environment

"Galace SQ mobile phone, also known as the Power Bank phone or the ‘Dumsor’ phone was in high demand in Ghana during the power crisis we experienced for more than three (3) years.

The not too fancy phone due to its block type size, served as reserve power source for people’s primary mobile phones during the frequent blackouts especially for people living in the capital, Accra."

Literally just used for its battery to charge their real phones in Ghana, lmao

Reminds me of the Oukitel K10000

I hope you're trolling because it's hydrogen.

Those showerheads were brought into Brazil by a italian (Lorenzetti). They're cheap as fuck, and the risk is not of being electrocuted while showering, but when you need to switch from Cold to Hot or Off. Most of the shocks I've seen were from people who tried to turn the heat up or down while showering.

We have the gas model too, but since the installation cost is through the roof (mind you, you get all that back just in electric bills), and most people who install it are dumbfucks, we actually have a higher mortality rate from the gas model than the electric model.

I had one of those in my old house, and it gave up after 6 or 7 months. The problem? The water here has all sorts of metals in it, so the stored water (when the shower isn't turned on) ended up corroding the circuits to the heater.

already posted
didn't you see the heater resistors?

I feel poor now, well maybe it's because I'm poor in a third world country.

And I do have a heater like OP's picture. I use it every day. I even cleaned it today, inserting a needle (a metal one, of course) in the holes.

We live our lifes in legend-mode

Favorite indeed, in the sense that it works that is. 200m+ people use it every day and there is way more accidents related to stupid people climbing utility poles and getting electrocuted than shower related ones.

Some extra info, here in Brasil all piping is made from PVC especially electric shower pipes, you really, really need to want to fuck with the installation to injury yourself on one. Power rating goes for abour 4.4kw/h for the shitty ones to about 7-8kw/h for the good stuff.

>third world smartphone
>OMG it's like a smartphone, but it has buttons and a little screen lol #wtf #3rdworldtech

>There's a loose ground just before the water exits
I wonder how long it takes until it rusts away

you need to put piece of glass between razors so that metal doesn't go into water

I would rather just take cold showers.

Those at-the-shower-head water heaters in developing countries work really well, and I assume are more efficient than keeping all the water in the pipes hot all the time as in developed countries.

For really basic-but-cool poverty shower tech, I've used a lot of solar showers in Africa that normally are OK for a lukewarm shower, and a couple times a "rocket shower" like this that are fiddly to start but give a proper hot shower: youtube.com/watch?v=sEh9Iop7dEQ

Hello Pahjeet

For all the shit they're given, take a look at the solutions used on some lesser superyachts.
They don't really have hot water tanks.

who are you qouting?

Suprised no one posted this one yet.

good joke

>and if a thunder strikes you streets power supply you might die if you are taking a shower at that precise time.
wew, who knew sound could be that deadly?

better than whatever crap Apple is producing

[spoiler]I still do that[/spoiler]

Your water heaters probably use an immersion heater with exposed elements, if not you have most certainly unwittingly used them countless times before. The heated shower head is essentially the same thing except you're not separated from the element by 2-3m of water pipe. It's not unusual to use metal water pipes as ground and in these cases not connecting the ground wire would make little difference to the safety of the head.
>water resistance is irrelevant, mostly because you body is a better conductor than water itself, so the electron will prefer to travel through you than through the water (unless you are taking baths in salty/ocean water)
Current is not carried by electrons in the human body or solutions.
All showers are unsafe during lighting storms.

Aren't virtually all water heaters gas-powered?

>subtle stoner joke.

I still use my torch and nail set up because its portable. E-nail you need 120/240v unless you have a portable battery operated enail.

In murica yes. In other countries not so much. We in burgerland have an obsession with heating and storing our water.

In Germany our water heater is gas-powered too

Gas heating is more cost-efficient than electricity

In states with lots of nuclear energy, electric water heaters are common.

basicaly, this

3rd world nations with these showers tend to have very short people on average so when a taller 1st worlder comes to take a shower they bump their head on the shower head and die.

I live in California and most of our WH are gas. I would prefer electric tankless though because of infinite heat.

water tanks are becoming less and less relevant now with tankless water heaters. downsize to tankless is that people that usually take long showers til the hot water goes out will take showers to infinity.

I live in a shit neighborhood in KY (college-fag). There are houses here that hit 2 million.

yes, rusting away copper, i wonder too

those are dry heating elements, they don't come in contact with the water. the wet ones are being phased out because they are shit to replace when they break.

STOP calling each other retarts

>kw/h
retard detected

>works on my machine :^)

But those things heat their own water. At least mine do.

Recently redid my whole heating system and switched to tankless. Holy fuck, best decision ever. Labor and parts was $8,000; easily the cheapest "how to make my life better" purchase ever.

What practical difference does it make in your life?
