An excellent presentation! Thank you. How about the water heaters with glass interior instead of steel? I suppose the benefit of glass is that you'll have no rust build-up.
I had a $ 1,000.00 bet with a contractor, him saying the vessel/container of the hot water heater is made of glass. Whereas in reality the vessel is made out of steel and glass lined. 1936: A. O. Smith patents the process of the glass-lined water heater. This concept quickly became the standard of the industry, making hot water an affordable convenience for Enamel is made of melted glass, often on metal. Sometimes called vitreous or porcelain enamel, it is made by fusing powdered glass to a base by firing, usually between 750 and 850°C (1,380 and 1,560°F). The powder melts, flows, and then hardens to a smooth, durable coating on metal, or on glass
And I always thought the heater sensed when it is out of hot water to then refill it’s self with cold water than light a fire to heat it up that way lol
@@michaelhughes5933 I don't think the video explained it that well and I don't know why there are comments praising the explanation. The host never mentioned anything about what happens to the water if it's not used (ie. sink faucet not turned on). Does water pool inside the chamber and stay hot, constantly fed by heat? Or does the heat only turn back on when water starts flowing again. And why does water become cold again in 1/2 to 1 hour if the insulation is so great? These are rhetorical questions to point out how this video doesn't really explain anything.
@@n89thanh --- because you can use up heated water very fast. As soon as it starts to leave the tank, cold water replaces the volume which was once occupied by the heated water, and that cold water comes from the supply side, aka the Utility Supply line. That water is cold, it's also flowing in at a constant rate, at about 20-30 psi, which is how we have water pressure. It's a continuous loop, but the water heater will eventually fall behind, which is why you have to wait between cycles, to get more hot water out of it. The longer you leave a Hot water faucet open, or use up hot water, the longer the water heater has to work to heat up the water in the tank, in this continuous loop. The water heater also has a thermostat bolted to the side of the tank, when the temperature of the water inside the tank drops below a preset temperature, it'll trigger the pilot, and turn on the heating element, to heat up the water in the tank. Periodically, the water in the tank, has to be reheated, when it sits idly. Smaller tanks run out of heated water faster, regardless if it's a Gas or Electric water heater. fyi. 😊
That really was a great and comprehensive introduction of how Gas water heater works. I am actually here to find out some way to automate my Gas water heater. I currently need to light it On and Off everytime, I need to use the hot water. By anyway, Can you guide me to correct direction. I am in need of a module, which contains a electric spark module, a electrically controlled thermostat, which can be operated by a software and a remote connection like a Wifi or Bluetooth controlled device. Please guide me in the right direction.
I am going to sound like a real dummy here: What makes the hot water come out of the tube at the top? Pressure from the cold water coming in? Pressure from the heat? Little elves with buckets? The question popped into my brain this morning, and I can't believe in all the water heater videos and graphics I've just subjected myself to, not one has addressed how the hot water actually comes out of the top of the heater.
Pressure from the main water line pushes through and out to the end to the shower head or sink. There's always pressure till you turn on the sink or shower
What descent said. A continuous flow of water dictates that cold water enters the chamber to be heated as hot water is used. The faucet goes on, the new cold water coming in pushes whatever's inside (in this case, hot water) towards the exit point (the open valve/now running faucet).
Shezzzz, ya forgot to explain how the cold water comes in from one side and pushes the hot water out the other-side, which means cold water is being pored into the hot water reservoir cooling off the hot water to some degree. Right?
I have an electrical 40 gallon bradford white Hot water heater and how water isn't coming out of the faucet. Any clues as to why? Their is no tripped circuit also. No water is leaking.
Does it heat water that's already hot or what? Mine seems to work despite being fed cold water. I found the receipt and it says water heater so I guess that's different than a _hot_ water heater.
Would someone explain to me why I see so many newer types of water heaters at the scrap yard, when I have an older craft master waterheater that I have had for almost 30 yrs and it still works fine.
So once the hot water i heated, wouldnt some of the heated water push back into the cold water intake and mix there? what is preventing the heated water from being pushed back into the cold water intake? Is there a backflow pressure valve? How does the hot water heater know it has heated enough water?
The water pressure going into your tank is what maintains the pressure coming out. Sometimes thermal expansion can happen, and you would want a thermal expansion tank to relieve the back pressure. Each water heater is equipped with a thermostat to tell the gas box when to kick on, as well as a temperature and pressure relief valve in case the tank pressure exceeds safety specs.
First make sure that the cold water supply pressure to the water heater is strong, and then check to see if the tube that runs into the reservoir is not clogged, you can unscrew it and pull it out. Then check to see if the hot water side out put is also not clogged. Doing this you should find your problem.
The water heater is an excellent conductor, transferring maxium heat from the water to the chimney. It does work both ways. Gas water heaters are greatly inefficient.
The gas water heater in the video, installed on the floor may be in violation of code. Most gas water heaters have to be installed on a stand at least 18" above floor level, to protect against explosion of flammable vapors.
That's a great thought! Water is an interesting fluid in that it doesn't expand very much when heated. But your thinking would be correct if we were talking about a gas. Pressure does push the water out, but it's just the pressure of your water supply, no expansion. It's the same water pressure that pushes your cold water out. Thanks for the question.
So you're saying the hot water in the tank is always under pressure, trying to push through the pipe and is only able to be released (coming out of a faucet) once the valve is turned opened?
Heating the water does create some pressure and will push a bit of water through the pipes, but not much. Basically when the tank fills and there's still water pressure coming in from the supply line, but there's nowhere for it to go besides the outlet, well, then it pushes it out and through your hot water piping.
As you use water in the tank, cold water is filled in to replace it. If you use enough of the water, only cold water is left. The water heater can't heat up water as fast as you can use it so you're left with just cold water in the tank.
To all the dip-bleeps with a peculiarly inadequate knowledge of English. It's a hot water heater because it is a heater that produces hot water: a hot water heater. There is nothing whatsoever in English necessitating that it must be "water heater" instead of "hot water heater." The logic of the formation is just different in the two cases. In "water heater," "water" refers to the input. In "hot water heater," "hot water" refers to the output. But of course I am explaining what everybody already knows.
You're dumb and I resent the fact that such a plebeian individual has such an undeserved sense of confidence and superiority. You look like a fool to anyone who truly understands grammar.
It's called a water heater cause it's heating up cold water which would be called (water heater) and if you call it a (hot water heater) in that case you would heating up hot water. That's not how it works lol
It’s a water heater, not a hot water heater. It’s an ATM, not an ATM Machine. It’s a magazine, not a clip. You meant to spell definitely, not defiantly. It’s nuclear not nuculer.
Anyone here know how use tabu? Lol means water bucket and the water scoop? I don't know how say that in English. I don't have that in Philippines before its hot there anyway. And that is for rich people only. I I'm not rich . Lol

The invention taken for granted by so many.
Who else is watching this waiting for the hot water to come back so you can take a shower ?
3 years ago lmao but me
A0
Lmao I’m literally standing in the shower soaking wet freezing my ass off waiting for some hot water to come back.
Man I've been in this situation 😭 was taking a shower then all of a sudden water went freezing cold ☠️
Hahahhahahahah im the bath now waiting for it to come back lmaoooo
Our water heater broke, and I decided to come here to learn more about how a water heater works. Thanks for the video upload.
We are truly blessed to live in a time with such commodities.
The music is so awesome. Used to watch Deconstructed in the year 2011. Every episode was a masterpiece.
ive been dying to know how this works .. i never knew theres an actual fire workin in there
there are electric ones as well
Thank you uploader for satisfying my random almost 12am thought of how a water heater works. Darn my wonderous late brain thoughts!
Ok.. I wasn't expecting to be this entertained haha!!
wow what a great video easily understandable and very detailed

Very entertaining and informative...thanx for sharing

It does.

Great Heater, if you use it correctly! Can even support low flow showering!!

So in other words, it's a bigger version of a thermos / vacuum flask you drink coffee from, but it's much cooler and actively working?! Fuck yeah!

And the role of the thermostat wasn't addressed.
Love this video… only problem… he’s saying it wrong. It’s a water heater. Your not heating hot water.

Is no one talking about the fact this guy's last name is Tendick? What a god.
Famous free electrons
But how the hot water not getting mixed up with new cold water when we are using it?

I just came here to ask if it's safe to drink from hot water. Or cook with hot water because my friend does that
Can I set it 40 minutes before I need to use the hot water?
what causes water pressure to be lost on the hot side, good pressure when you first open it then within seconds slows to a slow flow??? please help!!!
First make sure that the cold water supply pressure to the water heater is strong, and then check to see if the tube that runs into the reservoir is not clogged, you can unscrew it and pull it out. Then check to see if the hot water side out put is also not clogged. Doing this you should find your problem.

please the name of the origin channel

Had to replace lower components and afterwards felt on top of the world.
Mark off another skill as an uncertified repairman hown owner guy...
What the reason for only like 30 minutes at a time then it stops?
It's a vertical firetube boiler
loved this show! pity they took it of the air
3:15 so that’s why hot liquids are better in a Styrofoam cup.
so how does one "use up all the hot water"?
As you use water in the tank, cold water is filled in to replace it. If you use enough of the water, only cold water is left. The water heater can't heat up water as fast as you can use it so you're left with just cold water in the tank.
I’d like the answers to my test for this I’m taking a test on this what’s the answers
So, it could lose heat from the core
Mr. Tendick
I have that
now i know.
I thought the water heater killed someone. Sounds like an episode of unsolved mysteries
"Hot water heater". No one needs to heat hot water. I know, it's snarky, but just "water heater" will do!
.. but why do you need to heat your hot water
@johnlvs2run You could Fry an egg off those exaust gases...... Hybrid Water Heaters are the way to go......
I've never seen an egg fried with a gas water heater,but I've seen many houses and a restaurant get friend with one!
Not a hot water heater, just a water heater.

But the water heater itself gets hot. It will burn you if you touch it, hence: hot... water heater.

pretty sure that's not a hot water heater. maintainer maybe. def a water heater tho
It’s a water heater. If the water is hot, there’s no need to heat it. There for a “hot water heater” is pointless...
It's not a hot water heater. It's a water heater.
Hot water heater is redundant. It’s just a water heater. Why would you heat hot water? 😂😂
It is not a "HOT WATER HEATER", it is a "water heater" duh. If the water was already hot going in to it, then it would be a HOT water heater.
This is an old heater
Perfect insulator? Um, no. Not even close.
Heh I’m taking a shower.
Anyone here know how use tabu? Lol means water bucket and the water scoop? I don't know how say that in English. I don't have that in Philippines before its hot there anyway. And that is for rich people only. I I'm not rich . Lol
Yet the video didn’t clearly explain how water enters and exits the water heater...
It sure did. 00:50. What more is there to know?
pourquoi ya que des anglais la
Its a WATER HEATER not a HOT Water heater. It doesn't heat Hot Water it HEATS water
It's a water heater that's HOT silly.
I forgot how cheesy the scripts are in these shows
DON'T open it like they did that shit will explode like a grenade
Congratulations on wasting what looked to be a very good brand new tank.
You couldn't find an old one?!
terrible loud music. Hard to hear !!
So bored
No such thing as a hot water heater. There is a device that is called a water heater. Science channel you should know better. :\
