Rheem Tankless Water Heater Installation Part 1: sizing, buying and hanging 

This was an exact replacement for the old one that lasted about 10 years. ru-vid.comUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

This is a great video, you’re going into detail that a lot of other RU-vid videos are not really covering. Thanks.. Now, off to watch part 2.

My tank water heater is 35 years old and still going strong. :) But I am looking at replacing it with a tankless water heater. When I was a kid growing in in Europe in the 1970's having a tankless unlimited hot water supply was the most normal thing in the world. They were very simple units back in the 1970's. Nothing more than a flowswitch turning on a burner heating a metal drum that had coiled copper tubing around it. No venting.

You need your own talk show, you have the gift of gab. Thumbs up. Appreciate the decision points and how you went about describing what and why. didnt know you have 5? parts, so I need to buy tickets and reserve a time to watch. So far I cant think of anything you did wrong...time will tell : )

We’ve had our tankless hot water heater, made by Richmond for a year this month and I don’t think we would ever go back to a tank type water heater. I did the install the only thing I didn’t do was the gas one thing I do recommend is putting a one micron whole house filter that is my biggest recommendation with the tankless water heater have good whole house filtration

Awesome thanks for the series!

Thank you for the video. Mother is looking to get a Rheem tankless and am looking to install myself

Points out he’s from Chicago gets a like right away lol. Thanks for this video.

Nice video very informative though Scotty

I’m in Chicagoland area too and thinking of going tankless in coming weeks.

Thanks for watching! Like, Comment and make sure you SUBSCRIBE

I have a Navien, it vents with 2” as well. I also installed it myself so no I will not get warranty but I’m competent and I was willing to risk it… and I drained and kept my old tank unit in case something goes wrong that I can’t fix myself and it takes a few days to get a pro in. It should also be noted that since you installed this Rheem yourself you too will get zero warranty support FYI. That’s the caveat with ALL tankless water heater brands.

Any reason you couldn't have come right out of unit with a 90 and put the valves horizontal to give you more room? Thanks!

ground water is at a constant temperature regardless of the season. Because ground water is constant, ground source geothermal systems function properly

6 years for a hot water tank!!?? Here in B.C., Canada, a replacement HW tank is about $1700 Can ($1350 U$) installed all in. I'll be damned if I'm shelling out that kind of coin every 6 years. I just replaced a perfectly good tank after 18 years and only because my insurance policy says it needs to be changed every 10 or they will not cover any damage. So I live dangerously. I vowed to go tankless with this last swap but caved due to the $1800 price tag. Also here in government bubble wrap safety Nazi Canada, only a certified gas fitter is able to install any gas appliance. In fact, you are not allowed to take the appliance from the store. It must be picked up by the certified dude.

Scotty I LOVE your videos! They are Flippin awesome! I am getting ready to get my own Rheem natural gas tankless and thanks to you, install it myself! (got a plumber buddy who's gonna teach me how to do the gas piping but otherwise it's all me) I can't seem to find the model you used though. Can you post that? Did I miss it? Thanks again and God bless 😊

I believe Navien has to be installed by a professional to get the warranty. This will cost you about double. Good call on the Richmond

I dont want to sound like one of those "you messed up" know it alls. So in the nicest way, when installing my water heater I was unsure of the air inlet and exaust specs. So I called Rheem and asked them. They recommended at least 12" updraft from the unit before the first elbow. I do not know the reasoning for this it is just what they told me. So off to Home Depot I went to get 12" water pipe and the lowered then unit 12". Other than that good video.

Home depot brought me here! Thank you I'm thinking about installing one . How is it holding up today? besides the valve kit and PVC pipe and fittings , nothing else is needed?

Could you in theory just leave the intake pipe in the room so you don’t have to run two pipes out? I’m asking because I’m looking to do this to my home and I’ve only have one exhaust outlet going through my roof.

Save some time and start watching at 9:30.

This is a good video, mostly how it does touch on an issue I haven’t been able to find any support on and that’s the water temp. I have a rheem professional tankless water heater and live in south Texas. When the temperature starts to drop in fall, it always trips the breaker. Never happens in the warmer months. Any idea how to address this?

He made it harder than he should have been. Should have put it right where the old unit was and frame and hang

I searched through the comments but didn’t see anything in open air venting. Code says you can vent to open air as long as you have “X” number of square feet available or an opening to the outside. Living in Las Vegas, I have two 4”x8” openings in my garage wall. Is there any reason I can’t vent with the standard “B” vent from my tank heater and draw outside air from the garage wall vents?

Why PVC for the air intake and exhaust instead of alluminum?

Size matters.

Only six years they last 30 years here in my house and work perfectly we just are getting a new tankless one just because the old 30 year one is not working so well. My grandma still has hers it was her grandmas my great grandma 👵 ;):)

You need to post a parts list, good video but not very helpful if no parts list to duplicate the install.

Hey Scotty ... I only watched a few minutes into this. Let me ask you, also maybe make a video on this topic. Do you think someone who has DYI experience can do this themselves? I got a fooking crazy quote from some pushy Home Depot, "come to your house" quote that make it seem impossible to afford. I've put in a tank water heater 10 years ago for my Dad in his old house that he converted into a rental home to help pay for his nursing home care. So, if I could do that, you think that it is possible for me to do this -- if I watch you video and pay attention? Also, how does the damned warranty work -- if you do it yourself? I read somewhere that Rheem (or maybe it was Navien) won't cover it if it is not from one of their personally selected installers. So, are your parts covered if they go out with no fault of your own. Anyway, thanks for a video series. I plan to binge-watch it, but I'm tired after dealing with Home Depot people and then one their "salesmen" (you know what I mean) coming to my house. Damned tired and little pissed that they want to make three times what the unit costs in labor for the installation, or that's what I am guessing they are wanting to charge.

Why does it say rheem

anyone know the model number for the mounting bracket

...was für eine primitive Kiste!

So fucking lucky you did not get a Navian they all blew up and caused many house fires.. they are under a massive class action lawsuit

You live in a cave?

Stop doing your own installs 🙄 “simple” mistakes like this is what can kill families. Put away your little tools you bought at harbor freight, and let the pros do their job.
