How Do Gas Water Heaters Work? | Repair and Replace

This guys to inviting 😂

The dog wisper gets around.

When a water heater is set to high (say 80 degrees) and reaches this temperature, does the burner go off until the temperature drops several degrees and then start up again, a process that happens constantly? And isn't this similar to the way a wall heater works? Thank you

The reason why I’m here is because my sister takes showers for about an hour each night and I want to know how long I have to wait until I can finally take a comfortable shower it ticks me off so bad

I wish that you were here and could help me with my hot water heater

I've been interested for a while to understand the difference between north American heating methods and what is used here in the UK and most of Europe, is a traditional water heater more efficient or less than our method, that is using a that feeds hot water from the heating system through the hot water tank inside a coil, keeping the two separate, are heating systems going down that route in North America, or is the use of a Furness essentially what prevents this method from being used, second, if you have a convection heating system, do you have a separate boiler for heating or does the water heater provide this function also? And if so, why has Europe and the UK not adopted this method instead of our indirect heating methods used (a boiler and hot water tank) or simply a combi boiler which has the limitations of only being able to supply usually one bathroom with shower or bath. (Ps , I know the main reason you guys use a furnace and hot air is so that the same ducting can be used for AC in the summer, something that isn't as required here as in the UK at least, our temp doesn't get hot enough often enough to justify AC as well.

Good job

Excellent video!

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

Bardzo profesjonalne wytlumaczenie .Super !!

Wow a😮mazing video well explained

👌👌👌

I have a power vent water heater, do you have a series on just those kind?

👍👍💕

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 dad

Excellent video. Thank you so much for this simple, easy explanation of how it all works.

What about indirect unvented water heaters?

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!

With gas hot water heaters, there is a tiny screw that mounts the pilot assembly. A year or more ago I lost that screw changing the $20 pilot assembly. It is not obvious that the pilot does not sit on the burner tube flat spot, but instead mounts offset. Sitting the pilot not where it belongs but just offset a bit causes it to blow out and readjusting the position fatique breaks the thermostat tube. So to change the $20 pilot assembly, turn off the gas and remove the whole burner with one compression fitting and use the mounting screw on the pilot . Then connect the pilot gas tube and the thermostat tubes.

I found the screw and slid out the whole burner assembly to mount a new pilot with the screw. A years worth of hot water heater grief instantly went away and operation became perfect again.

This shows that some very tiny stupid misstep can cause a lot of grief. Little things matter.

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?

I'm a DIY'er. This is easy to follow and understand. Thank you!

Excellent Video!

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.

Why does my gas WH make popping sound from down under about a minute after the burner goes out? I'm not referring to the sounds in the tank people talk about when there are sediments there. This noise is from around the burner/thermopile/pilot area I think.

Why would my taps get hotternover time? Faucets and shower will spike in hot temperatures, even when I lower the dial to A

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 😁

We wasted our money and time on a Richmond propane cold water heater.. Only had it for less than two years... It has a five year warranty.. I've called three different so called Technicians all of them





couldn't figure out what's wrong... Rweem or Reem
Called some one out of Kansas City Kansas named John he was hear about five minutes I explained what it was doing he went to his van and in five minutes it was lit had hot water for about six.months and now it's doing the same thing again.. Reem is like the Biden administration. Smoke screen's and run around hope in you'll get tired of them and forget about it. Well i'll never suggest a Richmond propane cold water heater to anyone... It would be nice to find someone who's. Qualified to fix it. But you know the old saying wish in one hand and crap in the other just to see witch one fills up faster... Need help ASAP...

dumb question but do I need to empty the water heater before removing the annon rod?

My hot water tank is leaking like crazy and smells like burnt plastic. Listening to your video is nice, but I am an old lady, totally clueless what any of this means. HELP! I called several places. Its Saturday night, no one answers. Am I safe til Monday?

Great video!

Could someone tell me which programs it's been used in this video for simulation

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

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).

Now for the pop quiz class.

Fantastic video, thanks for making it.

Superb video, but it would have been good to explain the "direct vent" style water heater.

I have been in the Plumbing profession for 35 years and I was never able to unscrew a Anode rod from a Water 💦 heater.

Thank you, very useful info

So it's
Basically a bomb that Durant blow up
( hopefully)

From an engineering standpoint, a tank hot water heater is so inefficient. Tankless water heater are more energy efficient especially in a mostly warm climate area.

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! :-)

and pay $500 for them to inspect, do nothing, and say its ok

After going through 3 water heaters in a span of 7 years, I started doing much more frequent maintenance. I flush it twice a year, and replace the anode rod once a year. It may seem excessive, but I have very hard well water and a water softener, which eats anode rods like my kids eat corn on the cob. Every time I check the rod, it's down almost to the bare wire. But at least anode rods are cheap; water heaters are NOT.

EXCELLENT!

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?

Good video. I wonder why the power vent types are not 3 pass vents
