I took a seasonal job for the park service and had full Hooke ups at a campground at 6,800 feet elevation for the summer. Ground water around 45 degrees. I opted for this model as it was about 10k BTU more than the rest in the price range. I’m a professional hvac/r technician and appreciate the simplicity of the design. The unit fit perfectly in the place of the existing hot water tank, wiring was simple and the interface very easy to set and understand the readings. I set it to 120 at first but was way too hot for showers. So I lowered it to 106 which was just right for 100% hot water shower. Takes about 20-40 seconds to reach steady temp. Half hour shower was no trouble at all. Elevation and cold input water temp also no trouble at all. No cons k can speak to, works perfectly and worth every penny to have unlimited hot water on demand vs 3 minute scramble showers with the old baby hit water tank.

The media could not be loaded. This water heater was easy to install, I am amazed by the quality of the heater, after turning on the hot water it starts up quickly and heats the water fast to your desired temperature. It has been about a month now and everything is working perfectly. I would definitely recommend this product to others interested. I have saved a ton of propane switching to this heater.

Great product with even better price. Decided to replace the standard and very small water heater and could not be happier. We do use a little more water, but its great to have enough hot water when we are all together camping. Pretty easy to install.

The media could not be loaded. I recently installed the Ranein Tankless Water Heater in my vintage Boler trailer, and I couldn’t be more impressed. Hot water comes on almost instantly, and the temperature stays super consistent, even during longer showers or dishwashing. It works flawlessly with my RV water pump—the water pressure is smooth and steady with no sputtering or flow interruptions. I also tested it with different flow rates, and this unit keeps up effortlessly. No need to fiddle with knobs or adjust every time—I just turn on the faucet and get perfect hot water every time. You can check the water flow performance in the video I uploaded. If you're looking for a compact, responsive, and reliable tankless heater for your RV or off-grid setup, I highly recommend this one. It’s powerful, efficient, and a breeze to install.

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.

Our factory suburban 6gallon began leaking due to failing welds. We needed to replace it. This heater came really well packed, double boxed with foam protection. It came with instructions and all the wiring needed. Installation was very easy and straightforward for the average DIYer. Fit the cut out for the heater perfectly without any modifications. The water heater is amazing. Heats up to temp within 7-10 seconds and the temperature stays consistent even during extended use. The temperature is easily controlled by the control head it’s extremely quite noise level. It even conveniently tells you how much water you’re using. I believe it is a great product and offers a lot of value for the money. It also seems to be pretty fuel efficient. I would definitely recommend. Endless hot showers are the best!

This is a nice water heater. The only thing. It took an extra week to get the door. We’ve used it for several weeks now. Once we got the temperature where we liked it, we’ve enjoyed using it.

Replaced a different brand tankless heater that had caused water damage 2 times. So far so good on this unit. Installation was simple and good hardware was included. You'll want some sealant and butyl rubber tape. Easy to set the water temperature and it heats up nice and quick and temperature stays consistent. Tankless is so much better than a tank model for an RV.
