    • It's affordable and it works
Material Type: 80,000 BTU Style: 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. ... show more

    • Fantastic product!
Material Type: 80,000 BTU Style: 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. ... show more

    • Works great
Material Type: 80,000 BTU Style: Propane
Easy install, works great takes slightly longer to get hot water to the tap than the old tank style but it never runs out of hot water. Love it. Uses less propane than the old one too.

    • Great water heater!!! Works as it should!

I purchased the 80,000 btu version of this water heater. I love it! It's been about a week since I installed and it is still going strong and working like it should. Whoever said this can't be used as a whole house water heater was wrong. It took some getting used to because I used this to replace my old 40 gallon tank water heater, and like all tankless water heaters there's a bit longer of a delay in getting hot water to the faucets. However once that hot water is flowing it's amazing. I took the longest hotest shower I think I have ever taken in my life!!! The only other quirk is the flow rate. Which I expected since I chose the smaller unit for a whole house. The flow rate is plenty to run a shower, run the washing machine, run the dishwasher or the kitchen and bathroom faucets. However when filling a bathtub there is no water restrictor so the tub has to be filled slowly. It still only takes 15-20 minutes to fill my cast iron tub. A little bit longer then when I had a tanked water heater but a small trade off for unlimited hot water! The only other thing to keep in mind is this water heater doesn't have a fresh air intake, it used air from inside the house. If your house is sealed up well and well insulated it may not be the water heater for you. My house was built in the 20's so I had no worries about not having a fresh air intake. ... show more

    • Surprisingly small and light weight.
Material Type: 80,000 BTU Style: Natural Gas
My five-star rating could change as this unit has only been up and running for a week. It was on sale for an irresistible price so I took a chance. It is rated higher than others at its non-sale price point, but it lacked the number of feedbacks that I would normally like to see. I eliminate dumb 1 and two star ratings but still pay attention to them. At 4.3 with no issues that seemed to be a roadblock for me, it was worth a try. I live alone so 3.6 gpm is more than enough flow rate, and 80,000 btu is plenty. Even two people could be using hot water simultaneously provided those outlets are low flow imho. It responds fast for my plumbing distances and stays on point with no temperature waffling...yet. My slight lack of confidence is based on the age old "you get what you pay for" mantra, but sometimes you get a gem. Other than awkward grammar at times, the instructions were pretty clear. MAKE SURE you have a gas line that matches or exceeds the btu rating of the unit. That was not clear in the instructions ... show more
