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.

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.

@@tomhill9027 This install would never pass inspection in Colorado or not in my county anyways. The issues you mentioned plus a couple more. 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.

This was an exact replacement for the old one that lasted about 10 years. kzfaq.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh 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).

@waynemartineau4289 3 жыл бұрын

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.

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.

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..

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.

@johnnyb8629 3 жыл бұрын

@@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.

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.

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.

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 👍

1. pex is resistant to corrosion and acidity more than copper is, I agree SharkBite's are garbage and not even allowed at most professional plumbing outfits 2. most residential codes do not require a neutralizer kit below a certain BTU value

This unit, like all the Richmonds comes with a built in condensate neutralizer.

Help ...my gas hot water .is leaking out overflow pipe or relief valve ,after i take a shower.... when it is feeling back up it shoots steaming water all over my floor .through the relief valve .ive heard it probably valve but i think its in the heating unit getting the water to hot ...plus its on lowest setting .any help would be awesome

@tibet1976 2 жыл бұрын

Nice video. Easy to follow. One question, what is the reason for having two valves on both the hot and cold? If you already have the valve kit that screws directly to the heater, why put yet another set before/after?

@jj6457 2 жыл бұрын

Just for whatever in case you need to remove the hot water heater maybe to a different location. Other then that there’s really no purpose.

Why do you have to run intake if you have oxigen from the old water heater vents Like the furnace

@jeffreyratay1148 13 күн бұрын

Can I hook into an intake and exhaust that is already there for my furnace. Is the same setup.

does the pump have to be installed right next to the tankless water heater? It seem to tight of a space, can i just install it down line some where more open?

I have learned to never use dish soap for checking gas leaks. It is a degreaser which will remove some pipe sealants and is corrosive and can rust steel pipe.

@andywahl9631 Жыл бұрын

Only use approved gas leak solution

@brucey2570 2 жыл бұрын

First question is, I thought you cannot run pex directly to your hot water heater? Second question is did you have to terminate any electrical for the tankless? I did a couple jobs before where I had to wire up the tankless heater. If i remember correctly, I believe it was due to them wanting to tie it in to their smart home system. Tekmar if I remember correctly.

Normally, you need 18" of approved piping away from the unit before switching to PEX. The Rheem and Rinnai models I have installed plugged directly into a standard outlet as it is only used for powering the electronics. I haven't done any systems that connect to a smart home system. Do you have a link of what type of system that was?

If it is close enough can you you use the old metal tank exhaust duct that goes up the chimney? If not, can you duct the pvc up the chimney?

No, this is a cold exhaust. Can not go in the chimney.
