These are pretty cool setups I was purchasing this one to replace another one come to find out it wasn't the heater that was bad it was a restriction in my waterline to the heater now that I fixed that it works very well it keeps pretty good track of a consistent temperature it does fluctuate a little bit probably 3 or four degrees of variation you can feel it but it's not extreme it works off of a couple of D cell batteries so there's no wiring and the settings are fairly easy to set comes with pretty much zero instructions but it is very easy and labeled well for all I would say this is a pretty damn cool setup mine is installed on my 2010 camper and works very well but my camper also is stationary I'm not sure exactly how you would go about putting it into a regular camper for travel because of the way that the chimney works and the fact that it needs to be mounted vertical but overall it's awesome we have two teenage girls that have to take 45 minute hot showers every morning so it works very well for that also thought since I have an extra one of these of setting it up to fill my hot tub with hot water because at home I have a standard hot water heater and it runs out after 50 gallons and I need 300 plus I haven't set it up to do that yet but I think that's going to be what I'm doing with the old one that didn't have anything wrong with it that I replaced the old one was three years old and worked well just the water flow would cause it to turn off and on and off and on because I had inadequate flow

I enjoyed the water heater while it was functioning. It took a while to dial in the controls(which were labeled backwards), but once everything was set, it ran well and consistently. I ran the unit conservatively and it was surprisingly efficient. During the last week that the unit was functioning it began to turn on and off intermittently during use. Finally the unit ceased to turn on at all. I replaced the batteries, tested the propane tank separate from the unit(functioned as normal), and did basic troubleshooting of the unit itself with no success. The unit was supplied with 60psi, potable city/county tap water. I live in Hawaii and the unit never went through any weather extremes. I'm typically happy to repair all my own things without pestering the manufacturer but under these circumstances I didn't want to void a potential warranty because the unit didn't look easily serviceable. I suspect the unit has a water flow sensor that failed. I've had it for less than a year and only installed it about 6 months ago. In that time I used about 30 pounds of propane before the unit failed. I can't seem to find anyway to contact the seller/manufacturer about warranty. If the seller contacts me to help resolve the failed unit I will adjust my review accordingly. As it stands I will only rate it 1-star as the unit should have lasted for more than 6 months, and 30 pounds of propane, use.

I used this for a few years to speed heat my inflatable hot tub. It takes a 6 person hot tub(280 gallons) from 62 degrees to 103 degrees in about 1.5 hours. Propane is cheaper than electricity in my area and it takes $2-3 in propane to heat my hot tub 40 degrees. Then I maintain heat with electric water heater. After 3 years out in the exposed weather the paint is starting to peel. The tiny filter in the water line input needs to be cleaned or checked often as a clogged filter reduces pressure at the flow detector(which needs 5 psi to activate the burner) and prevents the unit from firing. This 18L propane heater is great though. If using as a camp shower just be careful of how hot it can get with low flow and high heat settings.

NEW out of the box - Spot welds broken, heater flopping around in casing, knobs forced on shafts (split), could not pull off to repair broken spot welds. Flue (exhaust) very flimsy, not sized for standard exhaust pipe. 1/2" pipe in and out (not standard 3/4" pipe). That being said, even with all these problems, it fires up and works every time. Very simple design. Every thing is mechanical except the igniter. You really get what you pay for.

I am very happy with this unit. After wrapping all of the inlets with Teflon tape, I realized that in order to connect your garden hose, you will need to get a male/male adapter down to 1/2”. This was in stock at my small town hardware store. I hand tightened all of the connections and then gave it a slight tightening with a wrench. When you insert the batteries, angle the batteries past the tabs. It’s a poor design, but with a little patience they slide into the compartment past the tabs no problem. Just don’t force it because you will break those annoying plastic tabs. The case and finish on the unit is great. It’s very thick and solid and feels high quality. After I connected everything with the gas and water in, it fired right up !! The pressure is as high as anything I’ve ever had in a house and maybe better. The pressure is great. It was starting to storm just as I got everything connected and so I forgot to check the water temp at the highest flow rate and set in “winter” setting, but it was hot to the touch and probably way too hot for a shower. To cool it down a little, you just turn it more towards the “summer” side. The shower head isn’t the highest quality, but it works great nonetheless. For the price, I’d never complain. A high pressure shower head would be easy to replace if you want to upgrade, but the stock unit is fine. Overall, I give this unit a 5/5 star rating. I don’t know what more you could ask for. It’s great !!

I had to change my review from 4 star to one star because of a fire hazard and lack of customer support. I used the unit for 2 days and it worked very well. But I had it on a plywood board I had used with my other heater for years. I noticed the wood was charred when I put it away. When I looked at the heater the middle vent holes below the heaters were discolored. Upon testing it was pushing out extreme heat from this vent. The upper vents and stack were not nearly as hot as this vent. As you can see from pictures the top of the middle vents is brown and this was from only 2 days of use.

Our first unit made by another company only lasted 4 years. We use it for our outdoor shower. This unit is so much better. One of the features I like most is you can set the output water temperature.

The unit functions as advertised. It is a luxury to have hot water at my cabin in the woods. Customers should know to tighten the shower head hose by hand only. If you overtighten the connections, the plastic nut on the hose will break. The unit has abruptly stopped heating on two occasions now. Turning the water supply off and then on again re-lights the heating element, but it will shut off again within seconds. Water pressure is adequate and all is installed correctly. I am quite handy. I will observe the unit and contact the seller if the problem persists. This is the only reason I give the unit three stars.
