Natural Gas Tankless Water Heater, Indoor Max 3.6 GPM, 80,000 BTU Instant Hot Water Heater

The media could not be loaded. Recently we needed a new replacement natural gas water heater to for our secondary home out of the country where we are planning to retire in the coming years. After much research and looking around I had it narrowed down to two options and this one went on sale so I went ahead with it right away as the price was very good. I ordered this water heater to replace a very old tankless water heater that was at least ten years old likely even older The old one was failed and had minimal controls and required batteries to run the ignition and regularly failed. I priced a replacement at the local store and they wanted to sell me the same one we already had that had failed for a price higher than this new one. I chose this new heater for many reasons but one of the main reasons was the specified minimum water flow rate was very low, this is ideal as I have very low water pressure and don't want to bother with a Rotoplas tanque or pump right now. The low water pressure caused many issues with the old heater and often shut it down because it would not detect water flow to kick on as well as often shutting down from overheating because of the pressure differential when trying to mix in cold water valve on fixtures to get warm water, meaning you got straight hot water no warm water. These old heaters often have low medium or high flame levels and that's it, nothing in between. I mentioned all of this because this new water heater has fixed these issues as specified in the product page. This heater automatically controls a variable flame depending on the temperature you set it to. So if you set it to 110 the flame will automatically adjust to make the output 110 regardless of the flow rate coming into the heater. This is exactly what I needed for my flow rate being so low. The heater also has very sturdy mounting brackets to affix to the wall. Another feature I loved it it plugs into the wall and has a digital ignition so no more buying D batteries or coming home to a heater that won't ignite due to dead batteries, on top of that the heater has a powered exhaust fan that pushes the exhaust out of the included flue pipe. I also noticed where the exhaust vent comes out on the top there is a one way closing mechanism to open to let exhaust out but then closes when it's off to prevent dust or dirt and other debris from getting back down the vent inside the water heater making it last longer. The power also runs the display and the electronics that control the heater. The settings are intuitive and simple to figure out. It has some presets but I found them to be a bit cooler than I'd like but understand those with elderly or children may like these to reduce the risk of burning. The heater is surprisingly quiet and was easy to install with the easy to follow included instructions doubling as a wall template to show where to set your screws for hanging. The hot water is virtually unlimited and will keep coming as long as you wish so no more waiting between showers and running out before the whole family gets their baths and showers. For something as mundane as an appliance it's quite attractive and looks nice on the wall, it was also pretty heavy which tells me it's well built and the components seem. The 1/2 gas and water hose connectors worked with my existing setup eliminating any hassle of adapters or new hardware. It arrived very well packaged in a sturdy box and a plastic cover, screen film and styrofoam for protection. I'm so happy with this unit and hope it will give me many years of use. I can't believe it fixed so many of the issues caused by my old basic water heater. I plan to purchase another one but in the propane version for a cabin in the desert.

Purchased this for a tiny house cabin. It was super easy to install as a DIY. We purchased a 3 1/4" in bit for our drill to make the hole for the vent. After the vent went in it was literally plug and play - zero leaks. We had 6 people staying there over the weekend and the hot water had great water pressure and temperature was perfect. Settings are really easy to adjust, the shut off is easily accessible, it's really quiet and has not odor or heat coming into the space (the one we just replaced was ventless but put off a slight propane smell and pushed warm air into the room) This unit looks nice and fits well in out small cabin space. We had the unit installed and running in an afternoon. Pleased with our purchase.

My 15 year old tankless finally conked out after 15 years. I could have ordered a replacement heat exchanger. But for $100 less got a whole new water heater. Very easy to install. However I would advise you to get half inch water lines. And 1/2 inch to 3/4 inch nipples to connect to your pipes. Do not get 3/4 inch water lines and try to connect nipples to water heater. They will leak. Lastly, since 15 years has passed since I last bought a tankless water heater. I still can’t get over the fact that I can easily set my hot water to whatever temperature I want. Have 3br 2 bath house with washing machine and dishwasher. And this little water heater works fine. And hot!!!! Even if it doesn’t last 15 years. At $225. It’s a steal. Compared to the big name brands that charge $800 and up.

I’ve been using the Ranein propane tankless water heater for a days now, and honestly, it’s been awesome. We installed it in our treehouses for an outdoor shower and tub,our first guest loved bathing under the trees and stars, plenty of continuous... unlimited hotwater . Perfect for our setup; I can shower and tub can run through 1/2 inch feeds without it skipping a beat. I have installed a couple of RInnai on demands before, this setup was straightforward, simple temp presets depending on what you’re using it for. Plus, it’s compact and doesn’t hog space. . You'll need to get the maintenance valves to fit 1/2 fitting son the unit OR buy 3/4 to 1/2 adapters as the majority of the maintenance valves are 3/4.. It comes with exhaust which is nice! Definitely recommend it if you want easy install endless hot water without the bulky tank

It works but loses a lot of volume and pressure. My shower has awesome pressure through the cold side, but the heater loses so much pressure, I had to turn the heat up high to overcome the pressure loss. All in all though it works for my outpost bathroom and shower house.

Easy hookup, doesn't need a dedicated gas line and very quit, I recommend this unit as long as there is a water supply, propain and 120v (I run mine off a 12v battery & inverter w/100w solar panel and the lp tank and lines off a old grill ) i will be getting a second unit and tossing the one in my camper out. 5 hour shower if you so choose

En la descripcion dice que funciona hasta 3 llaves abiertas simultaneamente y yo solo instale 2 asi que funciona tal como esperaba, antes tenia uno electrico y se tarda el mismo tiempo en llegar el agua caliente cuando la tuberia esta sin uso despues de unas horas y si es mas econmico que uno electrico sin duda.

Works well now that I have the largest has pipe inlet available. Customer service was pretty good and helped me troubleshoot my issues. Packaging could be a bit better as I had some damage to the unit on delivery. If you are changing from a standard heater, do your research as these do not operate exactly the same
