As Jay Leno says, “there is always a guy who knows it like none other.” You are the Rinnai. We just installed our exterior unit. Best videos on tankless. Also love your shop! Thank you video on my channel!
Wow why thank you very much.
this country needs more people like you who are straight up and honest!!!
I will be installing my first Rinnai in a month. I may need to call you to discuss whether or not I will need a PRV. Thank you for these videos man, they are priceless. You are doing God's work for plumbers.
I emailed Mike about my Rinnai issue. Very soon after, we spoke over the phone. I can't say enough what a kind and intelligent person this guy is. Thanks for all your help!
Thanks again for your advice ! I swapped out an old unit that had a leaking heat exchanger for a whole new, identical unit. All the plumbing and vent lined up without much problem. Hot water again! For those of you out there who are contemplating work on a rinnai ....listen to Mike ! He really knows what he's talking about.
Tilting the vent to drain the condensation outside is a great idea for places in a warmer climate. The manual says tilted back so that the condensate comes inside. I believe the reasoning is that you could build up a giant stalagmite of ice and clog the vent
One of the Best Instructional Videos Ever! Clear, tight, concise. Information in every sentence. No wasted time. Right to the point with accurate info. You could teach in a Vo-Tech School. Thanks.
I just completed my RUC98i install in Michigan. I could not have finished without Mike as a resource. I called him 4 times over the weekend and he could not have been nicer or more helpful, especially since there was nothing in it for him. Rinnai should be thankful to have an dealer/installer like Mike. After Mike clued me into the aggravating hidden mixer valves in my master bath (no more daily complaints from wife about bath water temp), the unit is running great. Even with very cold incoming Michigan water, it is cranking out 130 degrees no problem.
First let me thank you for answering my call, and giving me the information I needed. I will continue to watch your videos, and try to learn as mush as I can. You are a very good teacher. Thank you once again for your training.
Thank you for the detailed description of the connection for the venting.
Glad it was helpful!
I was looking for all the extra part that goes with Rinnia, in this unit that is not included. And I enjoyed your presentation on the Rinnia tankless water heater.
This guy is frikkin AMAZING!! I had some questions about installing a V65i on my converted skoolie and he called me and helped me out! makes the internet worthwhile. Am going to post pictures when I'm done - THANKS MIKE!
Thanks Mike. I have a Rinnai unit in my house, been operating flawlessly foe 16 years. I clean it with a pump, a couple of buckets and vinegar. When I need a new unit it will be a Rinnai. Excellent video(s), keep up the great work!
Bob Colorado wow that’s great! I tell all my customers if you take care of the tankless it will last 20 years. I will forward your comment to the Rinnai Rep. I glad to hear it’s working good for you. Could you send me the model number and the state you live in. Mike
Hi , I’m hoping you check in often! I live in Belmont Maine in a Log Cabin that we purchased in 2021 , I would like to upgrade to a Tankless hot water heater. Please Know that this cabin is 100 percent off Grid with Solar and a Windmill and a 12,000 watt generator. With this being said this cabin has everything you need and does not suffer any power issues at all . 4season home with no problem, for 17 yrs by the Previous owner , we So the stand up hot water heater is propane fed , we would like to stay with Propane!! Also when we are not here the cabin is shut down completely!!!!! So the unit would have to have the capability of being shut off and restarted by myself . Just like the existing hot water heater,Gas stove, gas Fridge,we have now. The cabin has plenty of electrical boxes for power source, the unit would be in the concrete basement where the hot water tank is now . The Venting of the hot water tank comes out of the top , turns into a 90’ goes straight for 36’ thru wall to outside with a cap on it . If you could make any Recommendations for this Project ! I would Appreciate it . Thank You
Mike, thank you so much for taking time on a Sunday night to call someone 2000+ miles away! We appreciated your troubleshooting our lack of power on our Rinnai propane water heater. It was great talking with you. You are definitely an expert on Rinnai!
Mike-THANK YOU for answering my email and taking my phone call after your work day to walk me through my attic install. You are a gracious wealth of info. Sei fantastico.
Can I have the email please or phone number????
Mike thanks for answering all of my questions regarding how best to vent a tank less condensing water heater in my basement that needs to vent via my abandoned oil furnace masonry chimney. If you ever get to Seattle, look me up and the coffee or beer is on me!
Frank in Seattle
Mike was great! He spend a long time on the phone with my husband and I on how to install the tankless water heater. Very informative. Thanks Mike
First off, I want thank you so very much for your videos. They are awesome and gave me the confidence to tackle my installation after several attempts at getting a pro to do it (either they never replied or gave me a $5k+ estimate). We were without hot water for two weeks! It took me several days doing it alone, but I took my time, especially with the venting. Unit works great 👍. We have hot water 🙏🏻😁 Also, thank you for answering my questions via email! I seriously could not have done this install without your help!
Huge help brother. I know you must get a lot of calls and I truly appreciate you taken the call and helping us out! You answered questions for us that even tech support couldn’t.
Thanks again!
Mike, God bless you for these videos. Truly appreciate it!
Great Instructional! I love this guy. I'm a 30+ year gas tech. Never put in a Tankless. Your videos are going to be priceless. Thank you.
This guy is awesome.
I needed several answers regarding my Rinnai tankless install. I am not even in his area and he still took the time to talk. If it wasn’t for Mike my local installer would have made a few poor choices when installing my Rinnai. Thanks to Mike several counties over....I had a good install.
Thanks Mike!!!!!!!!!
I guess Im kinda randomly asking but does anyone know a good website to watch newly released series online ?
@Chase Tommy lately I have been using FlixZone. You can find it on google :)
I have to get back to work but I wanted to say, this is an Excellent Video, Thank You Very Much, You are an Excellent Speaker and I am going to subscribe. I am putting a Rennai 199 Hot water heater, pulling my own permits after our gas company wanted to charge me $4000 dollars to install. Thank You, Robert
Just wanted to publicly thank you for responding to my Hail Mary call last month. We truly appreciate your call, follow-up and are hoping that your reference comes through. Sincere Thanks To You Either Way!! 🙏🏽
Mike, good job on explaining the basics of a tankless water heater. This is much needed, I find many plumbers shy away from installing tankless heaters because they don't understand them, or they have had a bad experience with one when they first became available in the United States. I'm looking forward to future videos and will be telling folks to check out your channel.
R. Dowden thank you very much, that's why I started this channel. I too had very bad experiences with tankless heaters when my business was in NY. When we moved to Florida I researched and tried out Rinnai and never looked back. Thanks for the comment Mike
Wanted to thank you for this amazing video - I was able to buy this unit and install it myself, replacing my tanked water heater, and I couldn't have done it without this video and a couple of your other videos. My RL94iN has worked for over a year now with heavy use without even a single issue, and I give you all the credit for this. The detail you go into was just priceless and right on every time.
The RL94IN has wifi?? To be honest i want it as basic as it comes. I dont need extra shit on my wifi
@@humblebragger500 at the time I purchased it, it did not come with wifi - I think they sell a few compatible kits that add on this and other capabilities.
Just ordered a rinnai RU160 and vent kit to install under the house in place of the old tank heater. I'll be watching your videos for awhile, I'm sure. Wish me luck (and thanks for the videos)!
Super guy! Emailed him a question this morning and got a reply around noon! He told me to call after 6 pm if I had any more questions. I called and he discussed the issue completely and offered more help, if needed. Very knowledgeable. I am extremely impressed!
Just a fyi if you cut 3 inches off the plastic you still cut 3 inches off the stainless. It starts 1/2 inch longer so you take the same amount off each and its still half inch longer
mike, love your videos. between your videos & reading the installation manual cover to cover (several times), i have no doubt i can install the RU199iN i want and do it just as well as a pro, for about a 1/4 of the cost. however, if i do install myself, Rinnai WILL NOT honor their warranty. "In order for this warranty to apply, it is required that you use a trained and qualified professional who has attended a Rinnai installation training class before installing this water heater." that is straight out of their installation manual. i contacted Rinnai and they confirmed this is 100% true. Not telling you what to do, but maybe you should mention this in your videos. All of the confidence i have gained to DYI this unit almost made me make a $2000+ mistake. it's a machine, things will go wrong, and Rinnai would not have covered the repairs. because of this, i have no choice but to install a Rheem. i can replace the Rheem 4 times for what it would cost for me to have someone else install a Rinnai just once. still, your videos have been a HUGE help. thank you!
Call me at 19042385349 tomorrow after 5pm eastern time before you do anything and I will go over it with you.
Mike
I'm so glad that I found this. Other than contractors that hate DIY home owners (including my electrician brother some of the time) I don't see why anyone would give this video a thumbs down.
I was trying to decide which brand of tankless water heater to buy with the Rinnai definitely up in the running. I will go with the Rinnai mainly because of your videos and clear explanations. You have removed any reservations I had and answered any questions I have (and probably many I would have had).
I have a 1100 square foot house (built around 1945) in Michigan with one bathroom, kitchen sink, washing machine and laundry tub with a (new) well for a water source. This used to be our summer cottage and now a full time home. It's a small house but being I traded square footage for lake frontage it's what I have. There is just my wife and I now so there is no big drain (pun intended) on the water system so I figure that a 6.5 GPM 150K BTU system should work out fine. My one significant concern is the well water quality but being I am also doing a major upgrade on the water filtration system (which will probably include a poly-phosphate filter) I don't think it will be that much of a problem as long as I do the maintenance on the tankless.
My current project is replacing the mix of copper, galvanized and PVC plumbing with PEX and moving all plumbing mechanicals into a small utility room that also contains my force air furnace. I only decided to move everything into the furnace utility room because of the space saving feature of a tankless water heater. So being the current water tank is 14 years old and won't fit comfortably in this utility room and to me a tankless water heater is a 'no-brainer' it is the path I am going on. I would add that I am doing much of the plumbing work in an 18 inch high encapsulated (previous project) crawl space.
I think I will be going with the Rinnai V65iN. I would go with the Energy Star rated top line model however Rinnai 'mandates' that it ONLY be installed by a licensed professional or the warranty will be voided. With the Value line it is only 'recommended' to have a professional install it and there is no mention in the warranty that it would be voided if not using a pro. The price difference between the two would be slightly offset by the $100 rebate ONLY for an Energy Star rated water heater. Personally I can't understand why warranty is voided if a pro doesn't install the luxury Energy Star line but not the Value line.
Over the last forty years I have probably installed over twenty standard water heaters not to mention done ALL maintenance and renovation on any house I have owned for personal use or rentals including two that I built from the ground up. I always go by code and don't cut corners but I have done a LOT of cussing dealing with work that previous owners have done far to many times to count. On the few occasion that I have missed meeting code on anything the building inspectors always point it out and have me correct it. The inspectors have always been fairly strict with home owners over pros and I have learned that it is NEVER a good idea to argue with an inspector - even when they are wrong. I have had follow-up inspectors tell me that I did NOT have to make a change because the work was actually up to code before hand. It's not uncommon for building inspectors to disagree with what is code. But again it is not worth it to argue.
So after reading my very long winded comment I would appreciate it if you have any comments or suggestions. Thanks!
Thanks so much for posting this Mike. My son is going to get a tankless water heater very soon. This video as well as your "installation" video are very helpful! Bob in Virginia
Bob Troxell he will not regret it. The new Rinnai units are so very well made and if maintained every year will last 20 years. Thanks for the comment Mike
Thank you. This was very helpful. A different video mentioned the exhaust / intake as concentric; I had no clue what they were talking about except that I "assumed" (correctly). You went out of your way to describe the exhaust/intake vent kit. Very helpful.
More and more people are going this way to save money and not waste ... ideal ... and even so equipment is getting more and more efficient. The only issue is the cost of installation; pricey up here in the northeast.
The Rinnai Guy is the Man to watch! Clear, precise, and extremely informative. He even utilized his personal time to return my call and personally assist me with my questions that I posted to RUclips. Pleasant man to speak to. Thanks again Mike. Your help is truly appreciated.
Thanks, you've brought a lot of clarity into focus.
1961CDAVDABREEZER no problem. Thanks Mike
Excellent video you covered everything i didnt know. Too much trouble . gonna take the unit back and settle for a regular heater
Thanks for the help to understand how to put one in
Thanks Rinnai Guy! You just saved me money, and time. I have been fretting over how I was going to run this 3/4 inch pipe which I would have run off a capped 3/4" Tee coming off of an 1" pipe approx. 10ft away. Especially when I have a 1/2 inch pipe approx. 2 feet away from where I need to install my RL94I. I will used a Tee to increase that line to a 3/4" directly to the Rinnai as you said at 14:02 in the video. Oh yeah Mike, This statement is also a request for confirmation if I should proceed with this plan as I suggested.. Thanks for you knowledge. Looking forward to your reply. Thank you.
This was an exact replacement for the old one that lasted about 10 years. ruclips.net/user/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh 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).
Thank you for taking the time to make this valuable video .
Louie The plumber no problem
Great stuff. Answered all my questions about the installation of the unit.
Super helpful. I just bought at 7.5i and plan to install myself. This is so helpful - thanks
Mike you are the best at explaining details thank you 😊 🙏
Very knowledgeable , and easy on the ears ... it all makes sense.... Subscribed !
Awesome, thank you!
Great video. It was exactly what I needed to answer the questions I had to install mine.
Thank you Mike !!!
Happy Holidays!!!
Thanks Mike. Keep up the good job!
Finally someone who an explain why...Thanks Mike
excellent video thanks - busy installing a rsc199EN after our little takagi blew out after 15 years and this is worth gold! Will def be following up on that vinegar trick, maybe a short detailed video on that showing what u do (filter in/ out etc?). Thanks!
thanks for posting this. very helpful.
ou81218 no problem
Thank you for Excellent Video
New watcher and new subscriber. I've recently purchased a RL94iN. Gathering info for me to install. Thanks for making these videos!
Thank you for excellent explain.
It’s necessary at the tankless heaters installation of extension tank for reducing the pressure
Thank you
very helpful, thank you very useful information
SG thanks
Excellent Video. You make it look easy. The other video on Rinnai I saw had a guy spend 11 minutes on if you have a problem with your system it is because you did not hire a trained Rinnai installer. Since there is not one near me and I am very capable having built my own home, could a DIYer install one of these correctly? Your video makes it seem straightforward.
Jordan Epstein if your very handy and it sounds like you are. The gas line is the hardest. First question what type of gas do you have and how far away is the gas tap from where your tankless will be. If you go onto my other channel mikes wood shop there's a complete install of a rinnai unit.
If you can give me the number of showers in your house I can give you the correct size unit. Thanks Mike
So helpful, thank you!!!
The man knows his stuff
Scott Lundy thanks
Hey Mike, your videos are very well done. I like the way you present your information . My question is, how far of a horizontal run can you have with the concentrec venting? I am installing an Rinnia RUC80iN. I am about 12' from the outside wall.
Nice instruction, time to get ur done!
Great channel! Wondering where the video for the Rinnai V65i, mentioned at 6:20, might be located? I'm installing one right now and it would be very beneficial at this moment! Cheers
Great video. Oh and I see he's for the Imperium.
Thank you very much and yes a big Space marine fan been collecting for 25 years.
Outstanding videos, thanks. Had a question on sizing for replacing the 30gal conventional in our three season manufactured home lake cabin in MN. Debating between the V65IN and the V75IN. We have two showers with water conserving High Sierra heads, washing machine and dishwasher. Primary occupancy is 2 with occasional 4 and rarely 6, but since I am used to tankless at home, I don’t want to run short. Leaning towards the 65 but what are your thoughts?
Great Video! Although asked by another guest I was unable to find a response? Installing a RL75IN in a home with 1/2” plumbing. I can step up the line to 3/4 supplying the unit w cold water and obviously do the same to the line delivering heated water to main 1/2” water line supplying the house. Will this work or do you have to step up more if not all hot water delivery plumbing? Thanks
this guy is the best!
Kimberly Dee thank you very much
Thank you for the video
You say "Hit the up arrow till you hit 120" , but then you say you have to call Rinnai to get it to go to 120 . So which is it ? Love these videos , very informative .
That’s past 120 you need to set a dip switch Tom make it go to 140
@@TheBuddylab So he just mis-spoke at 17:45 , when he said there is a way to raise it to 120 by calling Rannai or by a qualified service person. Kind of figured that . Our last one went to 120 on its own , and we were wondering what to look out for when we get the next one.
@TheBuddylab my ru199i is always exhausting or at least I can hear it run through the exhaust but the in use button is not lit up when it does this. Vented with 3 inch pvc it's propane too..any thoughts?
Thank you Mike. This is probably the most informative video I've seen on RUclips. My question is about how to vent this unit if its on an interior wall? How far can I run the vent stack.
Call me at 19042385349 today around noon eastern time and I will go over it with you
SO my only hang up in swapping to tankless would be the venting. Current tank is in the middle of the basement venting out a chimney. It would be a long run (15 FT) of venting to get it to an outside wall.
Great Video very informative. I'm looking to buy the Rinnai V65IP. I'm trying to find the right venting kit to go with it. It is being installed in my basement where the old Gas water heater is located. Any help would be greatly appreciated!!
Such a fantastic video! I just had one installed yesterday and way too much of the white plastic sleeve was sticking out the side of the house. Looks like a missile hit us! I’ve asked him to trim it back and make it flush...I’m hoping he stands by his work and will do it for us.
Also, how can I be sure that there is a proper pitch for drainage?
Very Nice Video!!! I wish you were in the Albany Area. I would hire you!!!!!!
Enjoyed this video very much.Just have one try problem, try to cut down on your basicallys
Great videos Mike. Question about the Concentric venting: Limited options for the tankless concentric exit and it is near the fresh air intake, which is next to the Furnace exhaust. Can I exit the house near these existing vents and then add more sections of the Black Concentric pipe on the exterior of the home to vent? Seems that code requires it to be at least 3 feet above other vents if this vent is within 10' horizontally. So I would exit the home and run the vent over on the outside of the home, to get the spacing. Does Ubbank make black extensions for the exterior? Thanks!!
Where do I find your video on the interior gas condensing unit install?
great video!
Mike, Do you have any recommendations for installers near the west palm beach area. Having trouble finding someone who seems knowledgable enough about these to properly install.
Thanks for making these videos, they are great and helpful for DIY community. I am also planning to upgrade to tankless water heater next week. I live in Texas and my unit will be in a closet 2nd floor. My vents are going over the roof. I do not have a luxury to drill a new hole for the new exhaust. I am thinking to use the existing vent for the final 2 feet of the pipe (PVC pipe from the unit to the roof and connecting PCV to the metal pipe 1 to 2 feet below the roof). Also I am planning to use intake pipe ending in attic instead of going out. Attic is huge not sure if it makes difference. If possible, can you please let me know if it is OK to connect to the last two feet of the existing exhaust and leaving intake end in the attic. Appreciate your (any one in the community) response. Advance thanks.
Really helpful video series. I'm looking to purchase and install a Rinnai unit for my home. You mentioned that both the inlet and outlet lines should be 3/4" for optimal performance. The current plumbing is all 1/2" to the faucets. Would I have to replumb all the exisiting 1/2" lines ? Thanks in advance & keep the content coming !
Thanks your very knowledgeable
Great video
Thanks Mike for the tutorial. Might you know the exact amps and voltage needed for the RL94iP?
Amy Moravec all you need is a 15 amp circuit. It is very important that it’s grounded. Hope this was helpful. Mike
Great vids. Typically what is your charge for a basic interior installation?
Thank you for your videos. Very instructive. Question: Can you cut the concentric vents to shorter lengths? Thank you.
Thomas Yergovich yes you can. You have to cut the outer pipe first and then you need to cut the inner pipe 1/2” longer then the outer pipe. The inner pipe the exhaust goes in 1/2” more then the outer pipe the air intake. I hope this was helpful. Mike
Mike, thank you for all you do.
I have Rinnai RUC98i and im having dust entering the inside of unit from the vent air intake. We live in heavy wind area and so dust is a major issue. Can i somehow cover the intake with a filter cloth similar to like air conditioner units have filters to catch dust in the house but let air circulate?
great video
Thank you 🙏
Great videos Mike. Because of you I purchased and installed a RL94i around mid March 2019 and it has worked great and would reccomend it to others. But now we have a problem and hate the thought of taking such relatively new unit apart for repair. We have not been home for the last two days so no hot water use. Now the unit is showing an error code eleven when we turn on hot water. After turnning the hot water back off the code clears. I have turned the heater off then on via the key pad, un-plugged the hearter electrical cord, then I removed cover and all looks good. Lastly I removed and inspected the igniter and flame sensors which were clean but wiped them off anyways, reinstalled the assembly and tested for good ingniter spark. But, still code eleven each time we try to use hot water. Next was search RUclips for a fix. I cant beleive the burner is dirty or plugged already. Any suggestion would be appreciated.
Excellent. Thx
I have purchased a Rinnai V65ip that I'm installing this weekend at my cabin. You mentioned that you have a video of the install from start to finish. I have watched several of your videos, but I can't find that one. Could you guide me to it. Also, I can't find your email you mentioned. Thank you so much for your videos. You have done an amazing job and given me what I need to do this right. Thank you!
Hi Mike like your video alot, deeply appreciated , I am gonna install 2 Rinai together , what is the best way to install them , can you please give me some advise.
Thanks in advance God bless.
Excellent!
Hi Mike, great video. is there a minimum vent length that you can use off the top
of the unit before a 90 fitting?
Mike, great videos and information. Man thanks. I have a 12 year old R85i unit that is giving me a code 12. I've cleaned the probes, burner plate and flue and replaced the gas valve. The unit worked fine for a day and a half and is back to giving a code 12. The unit lights, flutters and then goes back out. This is a propane unit and the tank is half full. Any ideas?
Hi Mike , great videos !!! I have a question , You explained how to do vertical venting through a roof but I'm in a basement and need to do vertical venting and go above the snowline. I'm coming out just above ground level and need to go up. Any advice ?
First of all I live in ILL. purchased a Rinnai tankless ( in transit ) tried to locate the gas pressure reg. you use. did not find yet, however all info I came across indicates one is not needed due to it is built in the unit???? With that said MY total system requires at max. cap 359CFH. Gas Co. installed a meter with 10lbs pressure and a cap for 425CFH. I believe a pressure reg. is needed to handle the 10lbs. What you say? Thanks for all that you do. You help a lot of people!
Thank you. 🙂👍
hi, can you use a piece of straight pipe about 12" to 24" going up and then into the 90 deg. of the concentric pipe? Or do you have to connect the 90deg elbow right on top of the exhaust of the tank? thank you.
excellent !
Great instruction! Just one question about venting !what if the vent is vertical straight up through the roof ?
RaKhem KhepeRa call me at +19042385349 and I will go over it with you
