Best explanation of a water heater that I have ever seen thank you so much
Thank you Brian! We aim to make all of our videos straight forward with some solid graphics. If you're curious we did a series on gas furnaces including one similar to this on How it Works: ruclips.net/video/tVLtJwix-_8/видео.html Cheers!
As a retired HVAC Tech, I confirm this is a great video. Some of this stuff was applicable 25+ years ago... the "troubleshooting techs figured it out on their own, the hard way, and some techs did not... In summary it was never this easy! :-)
Thank you Bob for sharing! It is hard to quantify the additive effect of troubleshooting different systems over the span of years. There are some brilliant techs out there, and their knowledge and experience is quite valuable. We're hoping that our Repair and Replace videos help increase the base level of knowledge of homeowners, allowing them to troubleshoot and identify some of their problems while still knowing when to call a tech.
Im a new HVAC tech and this is fascinating to me. We dont touch water heaters as HVAC techs at my company, that's for our plumbing department. But ive always been curious, and I wnt to be able to answer questions if i'm asked.
I appreciate you for two things. One, you explained the whole concept very clearly in minutes. Second, hats off for your patience and replying to everyone. There is a lot to learn from your videos. I’m subscribing to your channel. Thanks!
Thank you Ravi, we're just happy to help! I think you'll find that our other videos are just as informative as this. We have a whole "how it works" playlist that you might find interesting: ruclips.net/p/PLCo9SMjkdWBxWwrWCmzvRMSi2kLo9bGdp
Bardzo profesjonalne wytlumaczenie .Super !!
Thank you for watching, we're just happy to help!
Wonderfully explained and good visuals. So many customers have no idea how the heater works and I've had some ask how it knows when to fill back up with hot water, as if its empty at certain times!
I also deal in Stone lined water heaters. No anode rods!
Thank you Brandon! We put a lot of thought into how best to use the visuals, its definitely something that is difficult to fully grasp until you see a cross section of it all working.
Stone lined water heaters are great! I'm curious to see if they will become more prevalent over time!
@@AmreSupply Stone lined heaters last about 40 years if your water quality is decent. I service some made in '89 still. Dang four bolt elements are the worst.
Maybe if they become popular, you'll someday have a cutaway video showing the concrete and how it makes the water inert or how not all heaters require special anodes.
Starting HVAC school and this channel has helped me tremendously!
Thank you, we're just happy to help! You picked a fascinating field to study, best of luck to you!
Thank you for this excellent video. I see a previous comment about filling a kids pool. That is what started this repair. I ran a garden hose outside to the kiddie pool. The rubber seat in the valve had deteriorated and crumbled when I opened the tap. The kids had a nice warm pool but the valve would not close properly. Watching the video I got all the correct information to install this myself. You have saved me a $200 plumber bill. Also great to see a Canadian company making a difference for Canadians. 🇨🇦

Thanks AMRE Supply for such a beautiful animated explanation to us. Thanks
You're welcome Hemayet, the animations are something we find are essential for helping to show how it all works. Without animations its difficult to imagine as you can't really see inside a water heater that well.

Very well done. Thank you for an outstanding public service.
You're welcome! We're just happy that people are finding our videos helpful!
I think I just learned the problem is the thermostat in the control box (which is too old to find). My pilot stays lit but the burner only fired once for a few minutes until this morning when it was really cold out. It fired by itself and stayed on for several hours and this video is telling me that the thermostat (the part on the box that gets screwed into the tank) is the issue. I've watched so many of these, they all cover the same but this is the first one that explained what actual component makes the main burner fire. Thank You!
You're welcome, we're just happy to help. We have a dozen other videos on water heater repairs ruclips.net/p/PLCo9SMjkdWBwJ4a8MT2GKTDiSuvSHg6Xk but unfortunately don't have a video on replacing the gas control valve.

You're welcome Sunny! We're glad that you found it helpful!
Excellent video, great visuals, production values, and content. My gas fired how water tank does not have a drain location nearby, so I am looking at installing a system (of my own design) featuring a water sensor and bilge pump in the drain pan under the tank. The idea is that if water is detected in the drain pan, the sensor will cause an electronically activated ball valve to shut off the cold water supply to the tank. The bilge pump will pump the leaking water out of the drain pan to a nearby sink, until the water level drops below the leak point in the tank. I do have to find a bilge pump that will successfully pump hot water (some have water temp limits) but my bigger concern is what happens if the tank leak occurs below the gas valve/temp sensor? The temp sensor would no longer be immersed, would likely detect a low temp, and the burner would just keep burning. I don't care about damage to the tank at this point since it is toast anyway, but I am concerned that if the tank overheats dramatically it could start a fire. I really want to avoid hooking up an electronic gas shutoff linked to the water sensor since this would get complicated but perhaps this is the only way to be truly safe?
Thanks for watching. We're glad that you found the video helpful.
There are products such as the Floodstop Automatic Water Shut Off which seems to come with a built in alarm. As for protection: The water heater sensing bulb has a built in energy cutoff switch or ECO. In some models this is a fuse and in other models it is re-settable. Regardless if there is water in the tank or not, if the ECO gets too hot, it will shut off the gas valve. As well if your water heater has a thermal cutoff switch installed that will also protect the burner from overheating. waterheatertimer.org/images/Typical-gas-valve-500.jpg These safety devices protect the water heater and prevent the burner from burning when its not safe to do so.
Very exceptional video.

You're welcome!!
You're a life saver! Thanks. Worked on many electric heaters but this is my 1st gas heater. I must say, an electric heater is way simpler & a lot to go wrong in a gas heater. I don't understand why someone would install a gas heater. The heat costs the same now days!
Maybe it was there before like mine
@@Eastbaypisces stranger thing is I smacked the tank & 5 minutes later it was working! I know it will be back not heating again sometime soon. At least I had hot water for Christmas!
Thanks for watching. In Western Canada, natural gas historically was inexpensive so most homes were installed with gas furnaces and gas water heaters. In Eastern Canada, more electric water heaters are used as the gas prices are a have always been higher.
Electricity is 4 times as expensive as natural gas .
But the stuff they add to natural gas so people can smell a leak will make you sick .
Excellent conscise video!

Great Video.
Thank you Pedro!
thank you Vance for your excellent and orderly presentation. I have a question, in what way the sediments affect the quality of hot water? I mean the sediments are settled at the bottom of the tank, and will act as an insulation and result in more gas energy used to heat up the water. But other than that, it should not affect the quality of the water because cold water will be added once hot water is pumped up and the sediments should stay still and not be stirred up. Pls advise. thanks.
You're welcome, we're glad that you found it helpful!
You are right that the sediment generally collects at the bottom of the tank. In most cases sediment doesn't significantly affect the water quality but can increase the hardness of the water. As well if you notice any small white chunks it could be calcium deposits from the water heater. Since its not recommended to drink the hot water this shouldn't be a problem but it might slightly affect the water that you're using for showers etc.
thank you for your work

Great video! Would you be able to do a repair and replace for a tankless water heater too?
Thank you Cameron! We are currently filming a series on Refrigerator repairs and have a few more appliances to do first before returning to plumbing videos. As for tankless water heaters, they will have similarities to power vent water heaters and high efficiency furnaces. They have a hot surface ignitor, flame rod and a inducer blower fan. The difference is that a water loop runs through the burners to be heated instantly. You can learn how a furnace works here so understand some of the principles in action: ruclips.net/video/tVLtJwix-_8/видео.html
That was good, was looking ti biy a used Hot water heater with a power vent, nor sure i want to go thst route, looks like to many sensors that can go wrong, thanks again

Great clip
Thank you, we're just happy to share some good info!
Great video. 3:25 this is the standard design that’s been used for decades. It was a great design and worked reliably for decades. Yeah and just recently they’ve gone to the new designs that have all sorts of safety crap on them that makes them break all the time. Thermal piles to generate more electricity to run a smart computer board. Ignition vials that break often times due to malfunctions. All the stuff requires more complicated analysis to repair. Just give me the old fashion standing pilot light and I’m fine
Thank you for watching. There are definitely advantages to having additional safety switches and a control board that gives error codes but you are right that each additional part adds a layer of complexity and another point of failure. There is something elegant about simple old fashion systems. We've noticed this with appliance repair. The older models tend to be more simple to troubleshoot.
@@AmreSupply - tend to be? No doubt about it. Same goes with my washer. Just give me a washer that fills up with water agitates rinses and spins. I don’t need all this crap that does soft fabrics delicate fabrics auto sensing BS but once it breaks you need to repair man who can’t even fix it typically to come out. It’s totally ridiculous how complicated they make things for consumers now. It’s all around getting more money out of consumers for repairs. Thanks for the reply
Thank you
You're welcome!
Very educational thank you. My water heater burner vibrates when the flame kicks in. Can you tell me if it is a bad burner and will cleaning the filter help or do I need to replace the whole burner assembly. This is for a Rheem Ultra Low Nox water heater which I have had since 2014.
Thanks for watching! Its worth cleaning the burner itself and check to see how its mounted to see if anything is loose. You can see how to access the burner in this video. ruclips.net/video/Yx2gfgJB7b/видео.html
I'm building a simple 4" PVC van rooftop solar water heater. It will be U shaped and painted flat black. Otherwise no insulation. Being in Sunny Florida and storing about 8 gallons I expect the water to get pretty warm during the day, but I am wondering how long after the sun sets will the water still be comfortable (not hot) on a day where the water is above 90F at 7pm when the sun set and we hope to use around 9pm?
Thanks for watching! That seems like an awesome project! Considering that the temperature outside is still fairly warm, you likely won't get too much loss in heat over those 2 hours. If the water is stored in an insulated tank then it will help. Its hard to know for sure without all the variables.
Nice Thank you.
You're welcome!
EXCELLENT!
Thanks for watching!
Good job
Thank you!
RUclips for education, entry level for experience
Thank you for watching we're glad that you're finding these helpful!
Hey, thank you for the video! I came here because I now live by myself for the first time, and I have a gas water heater. My shower and the tap in the kitchen only deliver scalding hot water or lukewarm water, but it can never stay at a comfortable temperature long enough to take a normal shower. Is that usual with gas water heaters? I know mine gets checked regularly (once yearly).
Thanks for watching. If the water is scalding hot, then you can adjust the temperature at the water heater. It will take time for that to adjust, so it's not an instant change. You might have to adjust it, wait, test and repeat over several days.
As for showing, adding in cold water should be able to normalize the temperature. The shower valve mixes between that, so some valves may be more sensitive to turning the handles than others.
As well it depends on the size of your tank. This can also effect how long you can shower for with hot water.
Wow a😮mazing video well explained
Thank you, we're just happy to help!
Good video. I wonder why the power vent types are not 3 pass vents
Thanks for watching. There are some "direct vent" (power vent) water heaters that have an exterior fresh air intake vent and an exhaust vent and are not reliant on the room on the air.
Anyone watching this waiting for theirs to heat up
Thanks for watching!
Not me but is a bit funny 🤣
No, just want to know if my guess of how these work is correct, or if I'm wrong, and if I'm wrong, how am I wrong.
I am lol
Same here haha
I was in the shower and got curious, after some research I found this video. I now have a new appreciation for my hot water 😁

You're welcome Phillip!
This was an excellent presentation! I have absolutely no clue as to why this has 67 dislikes.
Plumbers that feel threatened?
Thank you, we're glad that you found it helpful! It could be the fact that the video doesn't cover tankless water heaters. At the time of filming these were not too common, but its something that we might return to in the future.
While the power rarely goes out where I live; in previous homes after storms, no power for a day or two. Plenty of hot water with a conventional standing pilot light water heater. Once asked a plumber about changing the anode rod. He looked at me as if I was nuts. Naturally, they want to replace the whole unit rather than the small expense of an anode.
Thanks for watching. Unfortunately there is a lot of incentive to up-sell and install new appliances, water heaters and furnaces. This results in a lot of appliances going to the landfill prematurely.
Fantastic video!
Thank you Hambone!
@@AmreSupply hi
Thank you for replying to all comments in this video, that's awesome. I think I might have an issue with my hot water heater or my plumbing, I am not sure yet. If I open a cold water faucet that is upstream of the water heater CW input, I get hot water in some faucets. The water heater has an input main valve in the CW leg, if I close it, and open a hot water faucet, I get cold water through the hot water faucet. I checked all the shower faucets mixing valves and it is not a problem with any. I troubleshot closing all cold water valves. My question to you is, is it possible to get any type of flow through the hot water leg of the heater if the main CW leg valve is closed?
Thanks for watching, we're just happy to help especially when it comes to answering comments! There are a few things that could contribute to hot water coming out of the cold side. One possibility is thermal expansion which can be mitigated using a thermal expansion tank as well you could also try turning down the temperature of the water heater and see if this helps. Another possibility is that your the copper pipes on the cold side were running close to a heating duct or to a hot pipe. This would heat up part of the pipe which would give you a little bit of warmer water.
Thanks for the help! :)
Great video, love the animated illustrations, I’m looking for animated illustrations like this for my online training course. Could you send me a link to the designer of the illustrations? I would really appreciate it.

Hi John, thank you for watching, we're glad that you liked the animations! All the 2D and 3D graphics are created by our talented in-house video team who is busy with their next project. To create graphics like this, we made a 3D model of the tank, opened it up and overlayed 2D elements on it to show the heat transfer and gas flow. This is similar to what we've done with our oven videos: ruclips.net/video/L9ZI5GyON9I/видео.html
There are lots of talented 3D modellers and 2D motion graphic artists and I'm sure there are likely some in your area that you'll find if you reach out. Cheers!
I watched the video and I have to thank you for ut but I having trouble understanding the safety system since why the pilot is there we could just connect the thermocouple directly to the burner and the moment the burner is off the valve close, or maybe the Pilot since it can shuts off and release only tiny amount of gas while the valve is closing right, since if we put the thermocouple to the burner directly, when there is no fire, while the thermocouple cools off and engages the valve the burner would have released a big amount of gas right ? And thank you again
Thanks for watching. A standing pilot water heater has a pilot flame as the source for ignition. A water heater burner does not run 100% of the time (or the water would get too hot). The burner only turns on as needed to maintain the set temperature. The pilot flame stays constantly, even when the main burner is off.
The thermocouple sits in the pilot flame, and verifies that there's a flame. Without a flame then gas will be released without combustion.
When the pilot light goes out, then the thermocouple cools down, voltage drops and both the gas valve for the main burner, and for the pilot light will close.
If the thermocouple was only connected to the main burner gas solenoid, then there's nothing monitoring if the pilot flame is still burning, and there's nothing stopping gas from being released from the pilot tube.
don't know how i got here, but it's 3am and I love this
Sometimes you never know where you'll end up but hopefully you found this informative!
wow good video
Thank you Robert!
How durable is the glass lining? I just picked mine up from Home Depot and it took some bounces I'm sure on the way here. Not to mention going from my tailgate to the basement.
Hi Kevin, thank you for watching. The glass lining / coatings are pretty durable and it will likely be fine. Even with a small crack in the lining, the anode rod will still protect the inside from corrosion as long as the anode is still healthy.
@@AmreSupply Thank you so much! I also have a 12 year warranty on it but I hope it lasts me 20+ years like the other one did.
Any helpful reasons why my hot water pilot light keeps getting blown out on high windy days ? It’s a standard propane heater tank. It just seems like to much air is somehow getting blown down the vent somehow. I’ve checked the vent a few time and everything seems installed correctly. Any ideas ?
Hi Jason, thank you for watching. First check for any drafts that would create negative pressure. As well there should be a good supply of fresh air for the water heater to run off of. You might also have a weak thermocouple, you can see how to test it in these videos:
Conventional gas valves: ruclips.net/video/Lu5GvbvspMw/видео.html
Electronic gas valves: ruclips.net/video/UXpmmGuewk8/видео.html
How do I identify the gas valve of the water heater when my on,pilot,off knob broken?
Thanks for watching. If you have a conventional gas valve, the main dial is larger and generally 2+ inches wide and the gas valve body is generally made out of metal. The smaller dial (on, pilot, off) is generally on top. If the smaller dial is broken, then you might be able to look up a picture to see what the dial normally looks like. If you can still turn the dial manually, the middle setting should be pilot and you should be able to push the knob downward. If you can light the pilot, turn the knob to the far side. If the pilot goes out then you'll know that was the off setting. If the pilot stays on, then you know that its the on setting.
Now if the dial is broken and can't be turned, then you'll have to get someone to replace the gas valve.
Hello - how much gas does the tank use to maintain temp when sitting idle? Would you happen to have a rough ballpark for a 50 gallon tank? Thanks
Hi Paul, thank you for watching. That kind of info is not readily available but you might be able to get some sort of answer here: waterheatertimer.org/How-much-does-it-cost-to-run-water-heater.html

Thanks for watching, and for the subscription. I think you'll find that many videos on our channel are helpful and informative. We're currently working on more appliance repair videos.
What's the difference between the pressure relief valve and the overflow tank? I know they work differently, but what's the difference in function?
Hi Mitch, that is a great question. If you're referring to the thermal expansion tank then this video explains when its needed: ruclips.net/video/E1B-jSamx5Q/видео.html
I have a 2013 GE gas water heater … pilot light stays lit but when I turn on the hot valve in shower cold water comes out then I get somewhat warm water not hot as I used to. You think it’s a bad thermocouple or bad gas valve ?
Thanks for watching. The thermocouple will not affect the temperature of the water. A weak thermocouple will however shut off the gas.
If the tank isn't getting then it could be helpful to do a deep flush to remove any sediment. Alternatively the thermostat inside of the gas valve could be faulty.
Superb video, but it would have been good to explain the "direct vent" style water heater.
Thank you, we're glad that you liked the video. The direct vent is something that is less common but you are right that it would have been a good addition to the video. When we do an update to the water heater series, that's something that we'll add in.
Thanks for the video. One question: In 6:40 it says about power vented tanks. "The pressure switch then verifies that there's enough airflow for combustion. Next the hot surface ignitor heats up and ignites the burner." Can you explain how the gas flow is opened in the process? Thank you
Thanks for watching. In power vent water heaters the gas flow is opened by the intelligent control valve. This has a circuit board and will control the power to the various components.
@@AmreSupply Thank you for your answer. So it sounds that the pressure switch, the hot surface ignitor and the gas valve are not interconnected directly but through the circuit board, and the intelligent gas control valve has a more complex mechanism that cannot be simply said if the pressure switch or the hot surface ignitor turns it on directly.
@@eidos4190 Yes its all connected through the control board. Think of it as a flow or a chain of events. Each event has to happen (call for heat is made, inducer blower runs, after several minutes the pressure switch is checked, then the ignitor fires, gas is released, flame sensor is checked etc) If one of the checks fails then the control board will show an error code as it knows at which part of the sequence the failure happened. The logic is similar to furnaces and is explained in this video: ruclips.net/video/b0sAGt-1niU/видео.html
Hi Sir, we recently replaced a new power vent water heater. My master suite bathroom (shower and faucet) doesn't have hot water but the rest of the house has. Is there any quick fix to this problem?
Thanks for watching. There might be an isolation valve that controls water to the master suite bathroom so its best to check that all valves are open.
@@AmreSupply Thanks for the quick response. I will check that.
Its probably a stupid question, but i was curious how does the pressure occur for the hot water to go thru pipes to sanitary fixtures? And how do I determine what pressure does it have? Or do I need a pump to move hot water from the tank to fixtures?
Thanks for watching. The water pressure is set by the utility company that supplies the water. You can buy a inexpensive pressure gauge and attach it to a fixture close to the water meter. The ideal water pressure level is between 45 and 55 psi This is enough pressure to push the water up to any fixtures in the home. If the pressure is too low, then it can sometimes be adjusted at the water meter.
On the other hand, tall buildings often use circulating pumps as the pressure alone isn't enough to get the water to the highest floors.
Thanku
You're welcome! Thanks for watching!
Actually i want to start a geyser company can you help
@@muhammadumar4728 If you are in North America, we can provide you with the parts you might need www.amresupply.com As well we have more videos on our channel that might be helpful to you!
I guarantee my anode rod is completely corroded away and the tank has probably 8" of sediment because I don't think it's ever been flushed in at least 10 years...oof...glad I watched this video!
Thanks for watching! We're glad that you found the video helpful!
It's funny, when I was growing up, I never once remember running out of hot water due to a bad water heater. Never remember someone having to come out to replace one. They seemed far more reliable and durable back then. My dopey mother once ran into our gas WH that was in the garage, with the car! You should have seen that tank! The huge dent in the tank was so huge that if you looked at it from the side, it seemed to go about halfway into the tank. Now, people would panic. She didn't act like it was a big deal so we all ignored it, never smelled any gas, and that battleship WH just kept trudging away producing hot water when we needed it. I am not lying. It lasted forever. I had a Whirlpool gas WH installed professionally back in 2015. Since then, the control valve has failed and I have replaced it TWICE. First one lasted five years, second one last less than two.
Thanks for sharing your experience. It's hard to know what exact changes have been made to the designs of water heaters over the years. I think the tanks themselves have been made in a similar way. The control valves have evolved. Electronic control valves have more points of failure than a conventional gas valve. There have also been revisions with conventional gas valves but less changes overall. The thermal cuttoff switch and flame arrestor screens have only been added recently, so that adds safety but can also cause issues if the switch is faulty.
I have been in the Plumbing profession for 35 years and I was never able to unscrew a Anode rod from a Water 💦 heater.
Thanks for watching. Some anode rods can be difficult to remove especially if it has never been removed from the water heater.
@@AmreSupply unfortunately Everytime I attempted to replace a anode rod the water heater was old and the threads were corroded in place. Even with PB Blaster I could not get them out. I had to recommend replacing the heater itself. But I have heard of people getting them out 😁
I have a issue you can help. My gas water heater set to 120. I have a pilot lit. When I open a hot water tap on faucet the burner does not light to continue heating the water. If I increase the temp and repeat opening a hot water tap, the burner does work correctly.
Thanks for watching. The burner will only kick on as needed. Based on how the sensing bulb works, it often takes a bit of new cold water before it will kick on and start the burner. This is not instantaneous. Turning the controls to a higher temperature will change the threshold of when it turns on. As well running a lot of hot water will require new cold water to enter the tank, which will trigger the burner to turn on.
If the water temperature is still comfortable and the burner still turns on and off as needed throughout the day, then you won't need to install a new burner / gas control valve.
dumb question but do I need to empty the water heater before removing the annon rod?
Thanks for watching. If your anode rod is positioned at the top of the water heater then you only need to drain a little bit of water before accessing the anode rod. You can learn more in this tutorial: ruclips.net/video/hTJv67imgaE/видео.html
My plumber mounted my power vent gas water heater directly on the concrete basement floor. It seems to be working fine, however this video shows air entering from the bottom to the burner. Is there any danger to being flush on the floor?
Thanks for watching. All power vent water heaters will have an exhaust pipe, some will have a direct vent intake as well. If it doesn't have an intake pipe, then it will draw air from below. If you look closely you might see small vents around the bottom even if it doesn't look like it is sitting on legs. If you see no legs and no vents then the water heater might be starved for air. If you're unsure then give your plumber a call to ask them to clarify.
I’ve got a question regarding my gas heater. Our gas company left a note when they turned on the gas that “Combustion air opening(s) should be in upper/lower 12 inches of enclosure”. Because the boiler is inside the home what does that mean exactly? Like air vents on a wall to the outside? I’d appreciate it if I can get an answer
Thanks for watching. Any gas furnace or water heater will need a proper supply of fresh air for combustion. The codes are local to your state, province or municipality and can differ in the specifics but this will give you a rough explanation: nationshomeinspections.com/combustion-air/
Hi there I’m having problems with my hot water system
I’m not getting hot water in my premises but water is getting hot and I can feel on water lines. What could be the problem with it.
Thanks for watching. If the water heater is working and the water is heating up, but there is no water to any of your faucets, then make sure that any shut off valves are open. If that doesn't help then you might need to call a plumber.
What happens if I turn off the gas line, will it know and not try to ignite a flame? It looks like I have a standing pilot water heater even though my home is new construction.
Thanks for watching. In standing pilot water heaters, if you shut off the gas, the pilot flame will stop burning, the thermocouple (or thermopile) will cool down and the control valve will close. Until the pilot flame is lit the water heater will not ignite the burners, this is because the control valve is not powered when the thermocouple is cold.
I have a power vent water heater, do you have a series on just those kind?
Thanks for watching. We explained how power vent water heaters work as it was important to distinguish them. Power vent are still less common and haven't been used for as long. We haven't created a series going into the full repairs as the need for repairs isn't as high as older standing pilot models. We are currently focusing on appliance repairs, more specifically a series on refrigerators.
@@AmreSupply mine was manufactured in 2003, but whatever man thanks
@@guywittamic Yes there are some power vent models that are around 20 years old, but there are still less homes that have them when compared to standing pilot. We will be creating a series for power vent and electric water heaters in the future, but we're trying to get some more videos for appliances first.
