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.
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.
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
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.
OK, but how is it pressurized like how does the hot water get forced through the rest of the pipes? It’s cold water constantly being pushed in that seems terribly inefficient and like it could cause it to explode.
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.
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
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.
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 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).
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.
water heater's middle pipe is a good conductor, so it can loss heat by heating air inside this pipe and it rises up then sucks more cold air from enviroment. that is not a one way heat transfer. It's speed depends on only delta T
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.
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.
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.
@@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. 😊
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.
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
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
