Hello. First time Rv owner going full time living for a few years. I know little about RVs and tankless h2o heaters. I did hours and hours of research and pulled the trigger on the Ranein Nova + 3rd gen. It arrived when expected, excellent packing & communication from the seller. 1996 travel supreme 5th wheel with an old suburban 6gal h20 tank heater that was leaking. I paid for the install as I was busy with other details. The old access was to large for the Ranien so a simple 2x4 frame was added in order for the new system to be mounted securely and then the old door from the last heater worked fine and mounted up to the new frame made. Very easy install for a mobile rv tech and he hollered when he turned the tap on to see how long it took to get warm, He was shocked, stunned and was thoroughly impressed. I added the Wasserman water pump with accumulator tank recommended and a nice adjustable pressure regulator for the incoming water. Got it all dialed in and took a 40 minute shower, same temp the entire time and no changes in pressure or volume. Its functioned perfectly for the past 9 days. A nice surprise was that it came with the outdoor fittings installed and the outdoor shower kit as well, which was not assured from the Amazon listing and some reviews made no mention of it at all. But mine came as pictured from Ranein. The unit is small, compact, ready with hot water immediately and will provide the same temp water for as long as you want or have water. I cant wait to put a makeshift tub outside and fill it with hot water on a cold clear night and watch the night sky. Seems as if it doesnt use much propane at all. Time will tell and the whole thing is so flawless that I havent once had to read the manual and figure out the control panel and all its functions yet. Allowing me to focus on more immediate needs. Personally, I dont believe I will ever own a hot water heater system with a tank again, home or RV. It is just endless exact hot water, no rush, no water getting cold and for just myself...it is bliss. 5 stars

My old suburban 12 gallon tank was leaking from the combustion chamber. So I researched as best I could over a week and settled on the Rainen on demand hot water heater. It’s now been installed for about two months of continuous use. It’s doing great. I spent November and December in Ohio where it got down into the teens for several nights. I do use a heated hose in those cold temps but it still had no trouble making 124 degrees. Even at near freezing with the hose heater off. It showed 35 degree inlet and 124 outlet. I was careful to order the 18x18 door combo which saved me $79 and had to frame the opening down to fit tank itself. It very easy, I just placed a 2x4 on edge along the top and left sides. I used Kreg pocket holes to hold them in place. Installed heater,and it fits perfectly, and then installed the door kit. Made all of the connections inside and had hot water in 30 seconds. I absolutely love it but I do have a few “complaints”. I would like a handing option on the door so that it can be made to open toward the front of the trailer. The T&P valve leaks above 60 psi and I had read this before buying it. With a regulator inline it doesn’t leak but it also can’t make enough volume to run two devices. Without the regulator it does fine. I need to find a high volume regulator. The ramp up for hot water is longer than a conventional tank. I knew this going in but when I dry camp it will be an issue for water loss. I think I will rectify this with a reclamation system. So the pros far outweigh the cons and it was half the money of the suburban unit I had that only lasted 5 years.

I'm in love with this hot water heater for my RV. I live in the RV during the cold Montana winters and my old one, fresh out of warranty, decided to go out and so I replaced it with a tankless hot water heater. No more six gallon shower where there is barely time for rinsing my hair. Unlike my old heater, this one has a thermostat, allowing me to change the water temperature, which is an added blessing. The best part was how easy this was to install. No one wants to work on RVs so finding someone to do this was a nightmare but you can reassure them that this tankless hot water heater will fit right in the slot of the old one and has everything you need to hook it up. It takes less space and fits neatly. I had hot water right away, with good flow and took a very long shower. I will be saving money this winter, by going tankless. And, I no longer have to schedule my showers around the laundry or doing the dishes. This was a great purchase and the person who installed it was very impressed. Runs on gas only.

Wow. Game changer. It was easy to install in my 2019 Jayco Eagle. I watched a YouTube video on it. I pulled the old one out. Since I had a 15x18 inch space, I grabbed a 2x4 and filled in the space. Slid the new one in. The gas was standard. I experimented with the wires. There's only two needed to connect it to the RV itself, and two for the control panel. Now we have continuous hot water. I no longer run out of water washing dishes or taking a shower. I have a combo washer dryer and my clothes come out cleaner. One of the best adds I've done to my travel trailer.
