Perfect for individual use or RVing with a partner, this tankless water heater starts up with only 2 psi, providing on-demand hot water for a shower or to wash dishes. Vent-free, compact design runs off of 2 D batteries (included).

Note: Not recommended for multiple points of use at one time as it will cause the unit to shut down.
Say goodbye to quick, military-style showers, refilling your tank, and waiting for the hot water to recover. This revolutionary, compact design replaces your outdated tank heater while taking up half the space. Enjoy the luxury of a hot 20-minute shower or the power of steaming hot water to wash those greasy pots and pans after dinner.
Unlike traditional tank heaters that require constant energy to keep your water hot, this tankless, propane-fueled water heater only uses energy when you turn on your faucet or shower, providing the ultimate efficiency at a campground or off-the-grid. The on-demand hot water has no recovery time, so you can wash dishes and then take a hot shower to unwind. It's perfect for full-time RVers hitting the road solo or with a spouse. You can also install it at the cabin for those weekend hunting trips or in other small living spaces.
This state-of-the-art technology is equipped with built-in safety measures to ensure you, your family, and your RV stay out of harm's way.
Its vent-free design has an ODS (Oxygen Depletion Safety) shutoff device that detects low levels of oxygen. Once oxygen levels drop below 18 percent, the flame extinguishes, and the fuel supply is cut off. The unit will not operate again until the living space is properly ventilated and an adequate supply of oxygen (20 percent) is introduced. When proper oxygen levels are restored, you can manually restart the unit.
For further protection, the water heater has a shutoff timer that will automatically turn off the appliance after 20 minutes of use, preventing the unit from overheating while also reducing the risk of hot water scalding.
Great product, super service. We are using it to heat water for the kitchen sink only at our summer cottage in NM. I could not get it to heat up at first, so I started with the easy stuff first and replaced the old propane hose and regulator, bingo bongo, problem solved. Puts out a good supply of hot water and we’re using it at 5700’ (1737m) in elevation. Max elevation noted on the box is only 6600, so happy with the results. etrailer did a great job in keeping me informed of the status of my shipment. Will do business with them again.
Does exactly what I needed it to do. It heats my hottub perfect. I am very happy with the performance of this heater and it works off grid...my happy place!
Received quickly after ordering, eight days. It was harder removing the old water heater and tank. This new tankless went in quickly and works beautifully. When the old heater died I was panicked but this 78 year old woman did the install with just a little guidance. Now I’m glad the old one quit. I love this new quick water heater, fast hot water that cost less. Thanks so much!
My order was apparently lost, no order was received by my order number. Whoever I talked to, never waiting or holding. She said she’d take care of it. That was on a Friday. I called back Monday, she remembered me, said it’s on the way and gave me a tracking number. Excellent.
Easy install. Heats very hot if you don't run your water at full blast.
Very pleased with our purchase. Would recommend it. Had it in our skoolie for a year and works fantastic.
The unit works great in my enclosed trailer conversion. Easily temperature adjustable and works great on low flow faucets. Highly recommend this unit
I couldn’t be any happier with the water heater

Still working great no issues
Works fast and very well. I would recommend as a replacement for the normal water heater with a tank.
Hard to install and did not work well
Bust and getting over hot and not worki ng
Installed in cargo camper conversion. Heated 60degree water to scalding instantaneously and uses very little space - I tucked it behind the oven where there was plenty of clearance based on specifications and was otherwise wasted space. Anxious to see how well it heats water once I take my rig ice fishing!
Quick and excellent delivery. Cannot wait to install in our 71 airstream makeover.
a business/man of their/his word! thank you
Pretty easy to install, need to make sure the hot air won’t trigger the auto shut off. That’s the case where I had to put my hot water heater. Can’t really use the cold water, have to turn up the hot water so it can keep up. Still can take a hot shower and do dishes, just not a whole lot of pressure. I am happy with my unit after working with it for a while. Easy and fairly cheap solution for my situation.
Showers are lukewarm in the summer and cold in the spring and fall. Use it in my camper van. I am currently looking for a new unit that heats adequately for my needs
Love the tankless water heater. Never run out of hot water with this one.
seta up in minutes on the outside of my renovated 64 Airstream. endless hot water.
Should have gave 5 star however I should have bought a bigger model. Good product and it's not a use once throw away design. I have had it hooked uo for around 2 years now.
I live in a rv and have a 4 gallon propane / electric heater Original in the trailer. When I bought this instant from etrailer I had forgotten mine had the option to be ran on propane. My plan was to try to get away from my electic heater using this one. Let look at model quick. I guees its the 30 gallon instant one by Excel. So I tried to get this to have hot water when I want without running my generator. My 4 gallon tank has an electric heater on it that I was using for a real quick shower. So when I hooked it up it was most easy to install right after my 4 gallon tank so that's what I did. So on impressions of the flash heater it seems like a great looking unit. I wish I would have got a bigger one. I think I paid around I 200 delivered so not bad on pricing. So I think it claimed around 20 degree warmer water. Anyway what I'm trying to say is like say at 40 maybe 50 degrees weather outside I didn't get a hot shower. It definitely helps my 4 gallon tank do its job and I can get away with just warming it up to warm and let the flash burner get it comfortable. It helps using both... I think two of the units in sync with eachother would be great. I would save up for bigger models if you have cold weather or maybe just buy two and you can run a line from one to another. During the summer it worked fine just turn the water onn wait a few seconds and bam hot water great time for easy shower. The product works great and have not any problems with it. I changed the d cell batteries with some new ones and the thing is solid and dependable I will probably be using it for a long time. Maybe one day go to two of them side by side. Also I plan on getting my original propane / electric to work on propane also. Maybe for this winter so I can leave it on and have hot water for my needs. The propane part fires up but I think the thermo coupler isn't telling the main burners to open up. I am also working on sanitizing my potable water tanks cause they are getting nasty and I can't drink my water right now. I love having my own rv and little upgrades and tlc can make your day. Etrailer has done me nothing but good business so I would recommend them for your instant and trailer stuffs. I did buy a flasher trailer wiring thing for my old truck that I could not figure out but it was probably my wiring/ mess of a truck k lol. Have bought a few items from these guys they usually surprise me with there service so that's why I decided to give them a hefty review plus I know us rvers tend to help eachother.
Our shop installed this water heater in a concession trailer, and holy cow did it deliver! Hard to say if it would keep up with a full-flow, longer shower, but it performs nicely.
It has been a blessing. Cost compared to others.. easy to install plus uses only 1/3 of the space.

Still working pretty good just has moments of going colder but it is easier to winterize Highly recommended
It was what I expected
The safety device on the inlet to detect flow is unreliable
thanks george. as a matter of fact i do not like my excel heater. i was never able to hook it up properly because the input threads won't seal properly. and, as numerous others noted, the input line is 1/4" flexible copper that is not anchored to the frame (even though it is designed to be so). therefore, any attempt to tighten the threads down twists the copper line. therefore, i must purchase my own termination and solder it on myself.
i just haven't gotten around to it yet. so, i don't even know whether or not it works.
so, no. i'm not satisfied. i am happy to post this to a review.

I wondered if you would be able to send a picture of the connectors on your heater. I reached out to the manufacturer who advised that the connections are one half inch and the copper is not flexible. If I could send them a picture then we can better see what is going on. If the fittings do not fit correctly it is recommended to use Teflon tape.
I haven’t hooked up the heater yet but everything looks great. The USPS destroyed the box but luckily the product was not damaged. E trailer has always been excellent to deal with. I will continue to purchase products from them in the future.

Hey Neighbor! That's one awesome shot! I checked out your IG account that's on your camper and you have visited some amazing places. All those views were breath taking. I would find it hard to pick a favorite spot. Is it the same for you?
