In this video Paul installs a tankless water heater in an existing house. This is for some family nearby that wanted to switch from their old 40 gallon to a tankless.
We're waiting on drywall at the Mad County Build, so it seemed like a good time to get this job done!
There will be another video in the coming months installing the tankless water heaters in a new build.

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).

@josephclegg895 2 года назад

Im a licensed master plumber and trained by rinnai us as a level 4 tech. I can tell you number 1 the gas line is undersized. Unless you installed the lowest btu possible unit your probably running 150,000btu min. You should be running a 1” gas line from the meter to the tankless directly depending on the length an material it could be larger. Second the flue although spaced properly which is good unfortunately it’s in an inside corner which will cause the exhaust to periodically be sucked into the intake which is bad news for the burn chamber.

Rinnai and Rheem both teach a very different setup and installation that would meet code. I usually do not comment but that install would make me nervous. The homeowner can pull a permit personally, but that would fail instantly with about six violations or unacceptable items. I guess as long as it works and nobody gets hurt.

@waynemartineau4289 3 года назад

Should take off the cover and check for gas leaks inside the unit, the manufacturers work needs to be field checked and twisting on water tank gas connection without a proper hold wrench can twist the connections inside the tankless unit and cause leaks. When tightening fittings in close areas always use two wrenches.

@johnnyb8629 3 года назад

done this many times when I worked in residential. There are a few things people need to consider before switching to one of these, first, if your house is still plumbed in old galvanized pipe forget getting a tankless unless your going to rip it all out and replumb in copper. secondly you need to have the right size gas line available and the BTUH available to run the tankless. I have seen on some small houses with small meters that have multiple gas burning appliances run out of gas cfm running multiple appliances while trying to run the tankless. I personally run both the intake and exhaust at the same angle just for the symmetry of railroad tracking the lines but to each their own.

@jeffhuntley2921 3 года назад

Johnny B. What about galvanized pipe doesn’t work with a tankless heater? I mostly switched to pex but some of my hidden piping I left alone

@johnnyb8629 3 года назад

@@jeffhuntley2921 The problem with galvanized pipe is that it rusts closed and restricts the water flow. Tankless water heaters heat large volumes of water with high delta T in short amount of time, water flow is important. If it works at all, it will only cause premature failure of the heater over time and unsatisfactory performance.

I have never had a tankless, have had water heaters installed myself pretty easy (last one cost me $600) lasted about 10-15 years little maintenance. Tankless DYI like this guy if not you probably need to get some pro to install $3k to $6k. 1 )Biggest selling point of tankless used to be instant hot water (I was always skeptical-how!?) now it comes to light that that is bogus... 2) Also big energy cost savings $8 a month = that will take 50 years to pay for itself. Total no brainer for me (my opinion vast majority of people) tank water heater until tankless gets way way cheaper which doesn't seem to be anytime soon.

@carlreichelt8724 Год назад

Well tony d..would like to go see u buy a tank heater now for 600 bucks u would end up with a 40 gallon cheapy from manards that would only last u prolly 8 years if u lucky & that would be no where as efficient..and yes if the unit is hooked up properly & every thing is sized accordingly or unit is not undersized u will get hot water to the fixture very quickly..far as only saving 8 bucks a month on cost to run I would say that's a little off as well.. considering the tankless does not need to hold water and continuously heat it as a tank type does or take the amount of time the tank type does to get u up and running to have hot water again after your teenager drains it with half hour showers or more..also most likely depending on what u would need to keep up with your use load u would only spend around $1500 for a quality brand tankless not 3 to 6k..well add around 3 hundred bucks or so for the material still way under plus u do your own like u said so save ton on labor too right..

Hard water is never a friend to a tankless. Low volume of water with a lot of Btu's= lime scale in the heat exchanger. At least once a year a clean and flush. Also no condensate neutralizer, by product of any modulating condensing unit is acidic water. It can and will eat through copper and cast iron pipe and etch concrete.

When I built this house 5 years ago I chose a tankless water heater/boiler. I have no regrets. I've never run out of hot water.

I do the annual maintenance on the water heater side which consists of recirculating a mild acetic solution for about an hour.

I saw a suggestion about screens on the PVC due to rodents. It's usually a bad idea on the exhaust, and some instruction manuals will say that. Flue gases on high efficiency units are cool and moist, so will immediately condense on cold hardware cloth screens. (rapidly) That starts a death spiral and an ice dam is built quickly in cold temps. The pressure switch sees an obstruction and the unit shuts down. In practical terms rodents don't enter, but ice dams will form all the time below 20F. FYI.

@JuanWonOne 2 года назад

Hey Marshall, you mentioned it was a family member you did the work for, and keeping costs down is pretty important. I dont know your background but I do have a couple of questions if you wouldn't mind answering. 1) why use pex over copper for the cold supply and hot supply? You secured the 2"x4" to the wall. Why not just use bell hangers to secure the piping to the to a 2"x 6" instead? I also noticed that you've used shark bite valves, I've had terrible luck with those on huge temperature swings. 2) do they not require a condensate neutralizer where you live? We do up in Canada. The condensate is very acidic and eats out old underground piping unless it's the very old clay tile. Great video otherwise 👍

I always use the Polish chart for torque specs. Tighten til it break. The 1/2 turn flex gas line remind me of that chart

I am planning on removing my water heater and put tankless water heater. My current water heater is using PvC for vent. And it goes up in the attic to the roof. So my question is can I use my vent That I currently have on my tankless water heater? It about 20 to 30 going up? Pvc

This doesn’t need an expansion tank? What if it does both hot water and heating concrete floor with pex in it?

You didn't mention that if the power goes out there's no hot water. Secondly the system has to be cleaned out at least a year. Another great video. Thank you.

How’s that different from any other electric hot water heater? U may get what’s warm in the tank but you’d have to use it right away.

The system really needed a anti-scale filter and a water softener installed together to keep from having to flush the system. It really makes a huge difference.

So I have heard that the maintenance is much more involved with tankless systems. Do you have a video on that aspect of the tankless water heaters? Thanks for the videos, they are very informative.

@MrPostFrame 3 года назад

We don't, but still need to do a video on the install in our new build. That's a great aspect to include in a video.
