My old tank RV water heater started to leak, and I thought it would be a huge and costly problem to replace. Turns out with this tankless water heater it was neither costly or hard to replace. With a friend I did the entire job in 1 1/2 hours. I compared 20+ water heaters and decided on this one because of the 65000 BTU specifications and high capacity. I was looking at other unites which were $50 cheaper, but decided to go with this one because of all the extra features not found on other units. The dual water outlet with shower head, and all the extra remote operations like water inlet temperature, summer/winter mode, DC voltage, water flow etc. are a real plus not found in other units. Well worth the $50 difference. The 36 month warranty gives me peace of mind, but having this unit in operation for 3 weeks, I don’t think I will ever need to use the warranty.

Took me 16 hours over 2 days because of PEX issues. Trying to get everything to line up in a small space. Worked great for about an hour, now it doesn’t make hot water? 😡

Replaced a 12gal gas/electric water heater in my 5th wheel. Installation was easy once I got the big heavy old unit out.I would not recommend it for dry camping. Uses a lot more water than a tank heater but once it gets hot, submarine showers become a thing from the past.My only complaint is the front cover on the control unit keeps falling off. Poor adhesive.

This tankless hot water heater is amazing! If you have a water supply you will have never ending hot water. It fit perfectly in our RV and installation was easy. Maybe took me a couple hours with removal of the old one. If you’re on the fence, just do it! You won’t be disappointed at all. The digital display is great for setting the water temp to whatever you want. There’s no interruption of hot water. The only thing is that I wish I would have done it a long time ago.

It was an easy install, removing the old one was easy too.Just find a low voltage 12v line too give it power. Reconnect the same gas line too the new tank check for gas leak after connecting.Display looks good 👍 Turns on when you need it & off when you don’t.

Very easy to install, some modifications may have to be done to secure it and depending on the RV you may have to come up with a way to fill the gap around the outside of the door frame and RV. I live in my Fifth Wheel full time and have been using this water heater for some time now and I have had great results and so far I have had no issues or problems. Water stays hot while running the sink and shower at the same time and doesn’t get cold until you are out or propane. Great purchase!

Very happy with this product. Easy to install and I love never having to worry about running out of hot water. Works well and simple to operate.

Replaced our tank water heater and never looked back. Saw the reviews on this and was concerned it wasn’t a name brand. Took a chance and glad I did. Put extra tape on the fittings and you wont have a problem. Works great on our XLR boost. Would recommend.
