It's affordable and it works
Style: Indoor Installation Only
Material Type: 3.6 GPM, Liquid Propane
I installed this hot water heater on a 400sq foot cabin where the old hot water heater had died. Local hot water heaters at Lowes cost over $1000 minimum for identical specifications due to lack of availability on big island. This heater arrived and was identical in size, appearance, and function to the previous heater, except it's digital now, so hookup was quite simple. The led displays are fairly bright, and it's simple to select the desired temperature. This hot water heater is able to sustain extremely hot water fairly indefinitely to a single shower, which was my target. The water flow is good at that volume, and it's operation is fairly silent. Overall quality of the unit seems fine, though time will tell. All in all, I would definitely buy this heater again for a small application like this.

Great heater for the money
Style: Indoor Installation Only
Material Type: 5.1 GPM, Liquid Propane
I installed this in the cabin we live in about a month ago and so far it's been working well for us. The distance from the heater to the various taps is fairly short and there is a bit of a lag getting hot water to the outlets,but I believe that is more of a result of the "water saving" fixtures we are stuck with these days and their flow restrictive nature. Water temp fluctuations have been minimal. Though we have noticed some due to the lower temp of the incoming water to the heater after the water has run for a period of time. We have very cold water from our well. The unit is a little noisy,but that is far from our concerns. My only real concern is the water heater cycling when running the washing machine when set to a warm wash temperature. It runs for such a short period that the water doesn't really get an opportunity to heat and I feel like the rapid cycling is probably not good for the heater. I feel this is more of an issue with the washer than the heater. Our solution was to run the washer on a hot setting and reduce the temperature on the water heater. Right now we just have a whole house filter installed in the inlet. We did have a Water Drop scale inhibitor installed,but it leaked and had to return it to Amazon for a replacement. Definitely on the homestead priority list as we have very hard water. All in all we have been pretty happy with the heater. Super easy install except for cutting a hole in the logs for the vent.

Very inconsistent too bad I can’t do a zero star…
Style: Indoor Installation Only
Material Type: 3.6 GPM, Liquid Propane
I paid more for this product than many of its competitors with the thought that you get what you pay for. I installed it in late spring of 2024 and it worked great through the winter. This is heating a tiny house and serves one shower, and one sink, neither are used at the same time. Winter hit and it started shutting down on me and after some research, I discovered that the propane tank needed to be kept warmer. Keep in mind I live in the desert of New Mexico. Once I built a heated compartment around the propane tank, I was sure that would fix the problem. WRONG! Now it gives a different error code and will produce 60-90 seconds of hot water before turning cold. Then you turn the water off and immediately back on, wait for it to heat up again and get another 60-90 seconds of hot water. After going through this mess of a cycle 3 to 4 times, you can actually get several minutes of hot water, up to about 5 and a half minutes before it gets cold again. According to the error code it could be one of 3 different problems, none of which make any sense. I bought this because I needed a DIY unit with no plumber fees. What I got was a mess. Shower time should be relaxing but my showers are now the worst part of my day…. Don’t buy this unless you don’t mind a product that is not dependable and doesn’t work as they said it would…. UPDATE 2-11-2025 After posting the above review, the company reached out with a misleading email which stated that they were offering me a full refund for my trouble. I wasn’t looking for that, I just wanted to post my experience with this product. When I responded to their message, they offered me customer support instead of a refund which I was very happy about. I need a working water heater, not my money back. I utilized the help from customer support and though the problem got better, It was still persistent. So I let them know this, hoping for more fix options. Instead they ask for my elevation which I gave to them. Now they have come back with a screen shot of their Q&A stating that the unit is not recommended for use above 2000 ft above sea level. I’m in the desert at 3600. Their offer now is to send me a shipping label and return the unit. I get that chemical reactions like cakes rising and things like that are affected by altitude but I worked 8 years a s a plumber and never once did we instal a water heater that had an elevation requirement on it. This is nonsense and completely unacceptable. I don’t know anyone who would ask about an elevation requirement on a water heater and more than that don’t understand why they would make a unit that can’t work at all elevations… don’t waste your time or money, there are far better products out there.

Fantastic product!
Style: Indoor Installation Only
Material Type: 3.6 GPM, Liquid Propane
UPDATE: I have abused this machine for almost a month now running it at max temperature taking 2 10 minute showers each day between me and my partner. It is extremely efficient, we use small 5 gal propane tanks that and they last roughly 2-3 weeks of us using them a lot. We also hand wash our dishes and it still manages to last super long. This is one of the few indoor built instant propane water heaters on this app and website. It does not disappoint, the price tag reflects the quality. It gives instant hot water and works amazingly as advertised. I've been using this for showers over the past week and it works great. It is super easy to mount and although it doesn't come with the fittings and proper connections for gas or water you can easily find these at your local hardware store. It will cost a little extra but I guarantee after you try it you will love it. I have this unit mounted in my camper that I live inside all year around and it is the greatest upgrade I've done to this place.

Really Good except one thing
Style: Outdoor Installation Only
Material Type: 5.1 GPM, Liquid Propane
Works amazingly even on cold nights (25°). My main complaint is the wired remote that is about as cheap as it gets and is not made to be outdoors at all for a unit that is a outdoor unit. Makes zero sense. So unless you're installing this on the outside wall of your bathroom keep this in mind. I just put it in a waterproof cellphone bag. But they definitely should do better on the controller seal it up!
