Hey everybody! We hope you enjoyed the video and thanks for watching! If you have any questions about what door you will need for your future install, details + links are in the video description. See you all in the comments! 😎

5 years later and this video helped me out immensely. Finally making the switch to a tankless unit. Thank you for the time and effort for the video!

I just recently discovered your videos. I can't believe how patient you seem with all the hang ups, road repairs, small projects where you don't have the correct parts, etc. I'd be cursing my way through someone videoing me doing these things. Great job and thanks for sharing your RV life with us.

I'm building a tiny house and I only hope as I progress through this I maintain the attitude you display! Thanks for the vid.

I had not watched your channel since you started. Im glad I refound you. I find you guys to be easy to follow and very thorough while being pleasant . You guys have a great relationship and it shows

Not sure if you’re all still active in those channel but this video saved my bacon big time! I had the same wiring configuration on my 2002 Four Winds 5000 and this helped to clear up confusion around the wiring!! Thanks a million!!

I have the same Atwood 6gal wh in my RV and the drain outlet at the bottom is supposed to have a plastic plug and nothing else. Many people do the petcock trick, but it is not advised as the Atwood has an aluminum tank with aluminum threads that can be stripped easily. It also causes the tank to be subject to corrosion caused by dissimilar metals coming in contact with each other.

Put in a Truma instant hot water two years ago in my older RV. Works like a charm, no problems. Love it and I do a lot of boondocking. Uses very little propane.

What a great video. I love that you go over the process of figuring it out and putting in the mistakes you make on the way. You're really good at explaining the full process.

Just bought a new to us pop up truck camper and now I want to do this. Thanks a ton for all your work showing this entire process.

Had the Girard 1st Gen installed in 08' and used it for 12yrs... Best add-on ever in our TT. We have just upgraded our 05' TrailVision to a 2018 Rockwood MiniLite, and are contemplating doing the install ourselves... Your video is very well done and I will save me $250 to do myself... Thanks.

Just want to say your video has been the best help when installing our Girard tankless! We came across a few little issues and we were able to resolve them by referring to your video...so thank you!

WOW you are a rock star, a brave rock star, to tackle that! Amazing. Glad you got it done. That water heater is going to last 20 years!!

I installed the Girard Propane Tankless in 2018 in my 2016 Fleetwood Storm 35SK. The problem that you had with the door, I just used the original door and used wood to block in the heater to where I needed it to be. I was lucky that it worked out this way because of the paint scheme on the Fleetwood was also on the door. With the problem that you had finding the correct door, I just would have drilled a new vent hole to match the vent pipe in the heater, (I was almost done with my comments when I remembered) The most important thing to remember is the temp. of the cold water coming into the Tankless water heater. The unit only increases the temp of the water by so many degrees. So if your water is coming out of your holding tank, the temp is the same for all of the gallons, BUT when you are hooked up to city water the temp will change. You have water in the hose and in the RV's water lines that is one temp. After you use all of that up then the water coming out of the ground will be colder. I had problems with the unit staying on while my wife was in the shower and giving her cold water for several minutes then it would get hot again. I called Girard for help and they were GREAT. It was suggested to make sure that there was no air in the water lines, like the outside shower. Air compresses so the water pressure going through the lines can change. Still having problems working with Girard again I was asked to check the temp. of the water lines that are part of the unit with a Laser Thermonitor. There were 2 bad sensors, and they sent me 2 new ones. I didn't want to wait so I asked if they could next day them to me if I paid half of the shipping. Again they were very helpful, BUT still had problems with the unit turning off while the water was running. We did a water flow test at the shower. I finally found a factory water restrictor fitting in the water line just past the kitchen sink. Made a world of difference. The tech guy at Girard asked if I could send him the pictures. (If you need the tech support contact info just email me PancoastJ@bellsouth.net) Now understand that every time that you turn off the hot water at the kitchen sink while doing the dishes the unit turns off because there is NO water flow. When you turn the hot water back on to rinse the dishes the water is cold for several seconds. The control panel is great, the display tells you the temp of the water, when the burner is on. In 2019, I added an electric 20 amp water heater next to the rear shower hoping that this would keep the water at the perfect water temp for my wife's shower. No such luck. When the water temp going into the electric would be too warm it would shut down to prevent the water from being too hot coming out. I was running the Girard to pre-heat the water, and I tried not turning on the Girard, and still had problems. So this year, 2021, I installed a 7-gallon electric water heater by the shower. I added a 2-1/2 gallon electric at the kitchen sink which also supplies hot water to the 1/2-bath. I also terminated the hot water line at the 1/2-bath to keep the shower hot water separated. I figured that every night I plug into the RV park electricity and heating the water is free, no propane to pay for. The electric water heater takes less than one hour to heat.

Oh my lanta! Y'all are in Nashville too! I love y'all. Thank you so much for these videos!

Good job Mike installing your new tankless instant water heater, Enjoy it ! Cheers !

Great job! Glad you are enjoying the water heater! Keep up the good work!

YOU ARE A NATURAL AT THIS! KEEP ON MAKING THE GREAT VIDEOS. THANKS.

I just ordered this heater the other day and got it installed yesterday. It was really not to bad of an install at all. It took me about 3 hrs or so and thats with stopping to go get parts from the hardware store. It was really nice to be able to take an almost 20 min shower with hot water without running out.

Good job! We had a 2017 Thor Challenger built, we had many upgrades added on this coach, and yes, one was the Atwood tankless hot water heater. This upgrade cost Approximately 4,500. About the cover/ door to the New unit, they painted the door to match the coach. Awesome job! Looks great! Can’t wait to use it! Thanks for sharing

I pulled the old propane water heater in my 1991 Motorhome and discovered it has a 120 volt element in the rear. So I’m plugging the propane line as I dont want to fix whatever is wrong with it. In the new age of cheap solar I’m going all electric and a diesel heater. Every propane appliance is going except the stove burners. I know the recovery time on the 10 gallon water heater won’t be very fast with a 1400 watt heating element but I can live with that. I don’t use very much hot water and can plan my showers and washing. My door is missing too. Since I’m going all electric I can fabricate a solid piece of tin for a cover. Dont forget a zinc anode in your aluminum water heater.

I’m a full timer and needed to no more info on this product. Thanks for the video great job I’m ready to buy!

I appreciate your videos and find them useful & informational. You do a great job, keep up the interesting KZfaq content! Happy Thanksgiving!

Great job! Glad to see the install of this unit. We have been considering a swap as well.

Great information! Will have to reference this in the future if we end up going the same route. Thanks for sharing :)

Great vide. I was thinking of getting this unit to replace my Atwood heater and I came across this video which helped me to decide to move forward with this unit.. Install is much less daunting after viewing this video. Thanks for your video.

Awesome video, I love the diy stuff!!

Great video. Super helpful for my project this weekend!

I have this one for many years,best thing ever could happen with

Excellent clear instructions thank you!

Great video! Explained every step. Thanks

Great explanation. Vicariously helping you rip that thing out of the RV.

You are a brave man. Good job!

Thanks for the video. Very helpful.

Thanks! I taight there were no option besides using tank on rv's. Question: How is it working soo far???

Thanks for the video, super helpful

Super helpful thank you!

great video, thanks!

Excellent video...as always! Thanks so much!

Nice DIY video. Appreciate it!

We are using an instant water heater in our bus conversion. It will be smaller than the one you have there. thanks for sharing.

I know this video is old but I just wanted to say a big thank you for providing such detailed information, our RV looks pretty similar to yours (1994 Allegro Bay 34ft) and we are thinking about the tankless heater

Love your videos and have subscribed. I like that you are 'common folks' (speaking financially) and not one of the many showing us how they do it, roughing it in their brand new few hundred thousand dollar custom coach. Your 'not' brand new RV gives me hope and inspiration that I can do it in mine. -- Sorry, that did come across rather snide. ::Sigh:: Anyway, you guys along with David and Jenni of Fate Unbound are two of my favorites. It's kind of funny, Michael and Jenny, David and Jenni, and we also watch some of Dan and Jen's videos. I told my wife, if we ever go on KZfaq she needs to change her name to Jennifer. Cash in on name recognition. 😅 Thanks for the help.

Awesome video, thank you

Great tutorial, thank you!

Love the real life struggles when it comes to remodeling, like on your video

Your wiring labels at 22:22 saved me!!!

Loved this, got to install one in mine.

Great video thank you..we will be on the road full time next march..following from wichita kansas

Thank you for the information, however I don't think I will do it myself because I like others live in the RV full-time and cannot afford to be without hot water. So maybe I will take it somewhere to have it put it. But thinking about that, that does not guarantee that they will not have problems either! lol I love your attitude of "Jumping right in!" lol That is how I do things! You put a "REAL" touch to the video and you made me laugh too. Thank you so much!

Hope you like it and that it works wonderfully for you and how you envision it. I'd love to have one, but from watching many videos about them the cons definitely out weigh the pros for us. You definitely need to do a follow up after being out on the road again and let us know if it worked how you planned and how you like it and a performance review as well. Thanks and happy trails.

you are very brave to do this repair. I could never. the people that disliked this video like cold showers

I heavily insulated my hot water lines. Helps prevent waste water tremendously. Gets hot water much faster especially noticible in cold temps.

AWESOME VIDEO !!!

Thanks for the wiring instructions, I was wondering about that extra blue wire to the ignition light and this was very helpful! I am about to install this into my camper to replace an Atwood 6.0 gallon as well. My only concern is that I don't think my old hot water heater is connected to a fuse. It is connected to the switch which is connected directly to the battery. Did you install a 10 amp inline fuse for the new hot water heater or was your old Atwood attached to your DC panel by a fuse, and you just tapped into that one?

Just a comment from the fact I live with a licensed plumber. It's not a "Hot" water heater. The water isn't hot going into the heater.. It's simply a Water Heater. Just cause my husband has made this statement so many times, I notice it anytime someone states it's a "Hot" water heater..

Good info good vid thanks

Great job

Great explanation. Very helpful. Thanks for sharing!

I’m sure that if a waded through all the comments SOMEONE must have written there is no need to heat hot water. It’s simply a water heater. The information and video quality is great. Just a little too long. You probably could have eliminated about 10 minutes and still covered all the necessary information. I make this suggestion on the probability I am not the only attention deficit senior citizen out here 😜 Anyway on a scale of 1 to 10 this video is a solid 8 1/2. Good job!

That's a really awesome upgrade. I travel with 3 woman and that would come in handy.

Great video. I watched another video about these. They set there’s at the temp they want the shower so they don’t have to fool around and waste water trying to get the temperature they want by mixing in cold. Thought that was pretty smart. Thanks for sharing this.

It's simply a 'water heater'. It doesn't need to heat water if it's already hot. Every time you say "hot water heater", god kills a kitten. lol

Great job thank you

Two thumbs up! Amazing video.

Thank you for this video just case i need change my bless you be safe

Love these DIY vids (doubt if we try it, though .. haha) ... but, these projects just prove most "mechanically intuitive" people can save TONS of money making repairs/improvements themselves ... thanks for sharing (very informative) ..

Great job.i have a similar c class and was considering the tankless unit but I felt your pain after the second door thing. I think I'll leave mine as is for now. Way too much work. But you did an amazing job. I just don't have your patience.

Great job. The three words I fear the most are, "some assembly required". The three words I like the most are, "hire it done!" This is usually after I have screwed it up so much that it cost a lot more than it would have in the first place if I had just "hired it done".

Great video...thanks !

I have had no hot water pressure since I moved into mine and when you showed the bypass I went looking and found out mine was almost completely shut off thanks for the info if not I would have had to buy a new heater.

Chris good video the only big problem for total novice when it comes to wiring. I wish they were more time given on these types of videos to the basic wiring that scares me the most in doing a novice repair. Removing screws and disconnecting things are never a problem it’s just the process of making sure you hook it up correctly so you don’t blow nothing up all in all a good video

My Landlord / Friend Chrissy and I are doing renovations on her RV right now. Thank you so much for this information :)

Great show, ky

Great video! "Don't push the red button!" 😱😱😱😜😜😜

Good job! Thumbs up

You’re the man....congrats on the instsll

The "wingnut" is called a petcock (yes, funny name) and IS the drain. Though, it looks like yours wasn't working anyway. You can find the same petcock valve on most pressurized water systems, including on the bottom of your engine's radiator. Love your video btw. Can't wait until you hit the road again.

After having the water heater for awhile what are your thoughts about boondocking with it and the overall performance?

Super informative. Watched several Vids on WH replacement and this is Top Notch. Wish I would have purchased a tankless. Note: There is no such thing as a hot water heater. Its water Heater. Thanks for the vid!

love the intro

Dude & Dudette... this looks great! I have to admit, it's probably more than I think I would do at this point, but down the line, especially if/when I go fulltime it might be worth it! Another great job... but I think we're missing someone... #moreJenny 🤗

Good job.

Awesome video and instructions!!..I'm installing the same unit in my 2016 Heritage Glen. My only concern is the unit's size difference. Looking forward to test it! Thanks for the video!

If I’m hooked up to city water with a hose do I have to turn the pump on

Love that you use a hacksaw to cut wood!!!

9/20/2019 How is the tankless doing now? If at all.

I love all the information your putting out as I'm in the process of buying and Class C.Do you make a video containing all your episodes. Thanks very much, Gary

maybe u can help, im trying to replace my atwood water heater 8.2 gallons serial # g6a-73 and the one I want to buy is a g62-8e 6 gallon, can I do it

nice video, seems like it is pretty easy..

Did you put some soapy water to that propane fitting? I like to double check, especially on reused flare fittings.

I just purchased a new Girard 2GWHAM. I kept having problem with my old 6 gal. tank suburban. I hope mine goes in smoothly.

I love your smile through all this crap we all are so glad it is not us having to deal with

like the vid but because of the Dexter lab reference you just earned yourself a sub. keep it up.

Are there specification restrictions to watch for or upgrades needed from an electrical perspective? Does a tankless water heater need to be on it's own circuit? What is the total amperage needed? Will it run AC/DC/propane? What have you noticed with consumption of fuels? With the rapid heating capability I'm assuming the original water heater specifications will not suffice. Thanks.

watching videos of not mechanically inclined people try to install things are usually hilarious

Do you need to cut out the bypass valves? Or can I just keep them on

I added this exact unit in my rv, and the12 volt seems sketchy? The thermostat will randomly blink or shut off? Any advice?

Where did you get the hardware to mount it with? And for the door to the unit?

Just wondering how long a 20 lb propane tank last? for this kind of heater? thanks!
