  • Great non-name brand!!
Material Type: 7.5 GPM, White Style: Propane
The media could not be loaded. I can’t say enough good things about this propane water heater. I’ve had it installed for several months now, and it has always worked. It reduces the amount of flame when you call for low temperatures or less water demand, but it’s fully capable of putting out scalding water. I have it set to 120° and that is plenty hot for us. I was having the house painted, and the guys covered the intake/export vent on the outside unbeknownst to us, and the safety features prevented the unit from firing up. Didn’t get my shower, but it turned out fine. When it was uncovered, the unit returned to perfectly normal operation. No resetting faults or anything. It was very easy to hook up and had ample instructions, though it did not come with the valves on the bottom. I had to purchase those extra, as well as the gas connections. At less than half what most name brand products cost, this is an exceptional value. Only heating water when you need it saves money on fuel cost as well. The diagram indicates it would be scary to open this thing up to service something, but the way it’s been working so far, I hopefully will never need to. It does need a 110v power outlet to plug into for ignition and computer components, but I’ve been able to power it with an inverter/generator so even in times of no power, you can still have hot water…. provided you have a generator:) I’m considering another for the other house where I have a tank full of hot water sitting all the time. The space I would save I could add a stack unit washer and dryer in that closet too. It’s very quiet as well, about the noise level of a microwave running, so putting it in an interior home closet won’t wake the neighbors….or kids. Very pleased with this purchase!! ... show more

  • Don’t do it. For any reason. The review I wish I’d seen.
Material Type: 7.5 GPM, White Style: Propane
Purchased April 6th 2023. Would give anything for a Time Machine. Professional install, everything done correctly and as suggested..and I can count on one hand how many times I’ve turned my water on and hot water came out the first try. It usually takes turning it off and back on 5-6 times before the water actually is warm. (And I’m talking let it run for 3-5 minutes each time). You can Forget an uninterrupted shower, It kicks on and off, throws error codes and shuts off while running. When it’s checked for errors nothing shows of course so there’s “nothing to fix”. Absolutely ridiculous. I’ll never own another one of these in my life. It simply does not work..unless you want hot water when it decides to work, but not on your time. I wouldn’t take it if someone paid me to. Not even getting started on the hassle it was to actually get it delivered. I’m done with it. It’ll be in my front yard tomorrow morning and I’ll have a traditional water heater. ... show more

  • Good so far
Material Type: 7.5 GPM, Gray Style: Natural Gas
So far so good, but the real test is how long it lasts. Feels solid and well-designed, so it's odd that the instructions are so horrible. I'm talking literally word-salad at times, with many half-sentences that make no sense at all, as if they decided to just publish a mock-up of the booklet before finishing the writing. But it's not rocket science when the unit is working, so you can probably figure everything out, but you'll need extra luck (or help) if you have unusual questions or problems. The brass-colored metals at the bottom of the unit are actually kind of cheap, but mostly the unit feels sturdy. I have gotten no error codes yet after more than a week of use. For the price, it seems a good four-star purchase, assuming it lasts for some years. ... show more

  • Temp is not accurate. Will Scald you! Do not buy. Set @105 and puts out up to 145. Watch video!
The media could not be loaded. I bought the Natural Gas tankless water heater last year. From the beginning it would overheat every time. The temp will go over the set point almost 30 degrees and scald you. I keep it set at a low 105 and if I do not run two sinks at a time the output will soar to 140 degrees. Then it will shut off and give cold water before it starts back again. I complained to the tech support many times. They had me turn the gas valve in half flow. No difference. They sent me a video on how to remove the cover and adjust the gas regulator inside the unit as low as it would go to choke down the burner. That did not work either. I have asked them to send me whatever part that controls the temperature output. The temperature setting on the front of the unit is useless as the unit should cut off at the set temperature. Not 25 to 40 degrees above the set point. We have two heaters in our house and this one is for our kitchen, guest bath and laundry room. If you use a faucet at half water pressure it will not even come on. It is either cold or too hot to use. We are constantly adjusting the faucet up and down when bathing our pet to keep from scalding him. Now it has been over a year and they could care less that the problem was never fixed. At least our other heater is a tank and works great for showers. ... show more
