DIY , watch your gas consumption go down
This product is what it says it is natural gas hook up 80,000 BTUs this unit is good enough to run laundry machine. I full bath in a few minutes. Endless shower approximately 123° perfect. The unit is very self-sufficient and remember to buy the connections they provide. Other than hooking it up to your waterlines in lit outlet very easy to follow instructions. FYI DIY compatible and do follow airflow instructions and don't forget about the bladder tank if you don't have one you'll definitely need if you have bladder water bad water pressure. Then after hooking up the natural gas line 2 unit double check for leaks you spray bottle with a little bit of dawn dish soap or dish liquid spray and watch for bubbles if no bubbles you are OK. Plug-in unit 120 outlet close by with a GFI do note that GFI should be on one breaker instead of existing plug. no need for wiring since it has a plug itself built in. Fits any exterior wall double chuck waterlines turn unit on by faucet automatically starts warming water. I hope this little review helped you out enjoy your blessed day , future pictures coming soon

Easy install, works as advertised
The real test will be durability. It has been operating less than a year, but for the price, this seems like an easy decision. Mine supplies hot water to three sinks.

So far, no real big complaints
I wanted to wait before I made a review. Its been running just fine for over a month now. The only reason I didnt give it 5 stars is because, there is NO hardware whatsoever, nothing at all. Be prepared to take inventory of what you will need to get it all, in 1 trip to the hardware store. Another thing I didnt like was, this is only made to exhaust out of the side of a building. I had to buy a 3" x 3' water heater exhaust tube from the big box store (on my 3rd trip there) and it worked perfectly. Other than hardware, exhaust tube and no instructions, it was very easy, straight forward, and works great.

Works great & Great customer service!
My Mom had ordered wrong one by mistake. Customer service was extremely helpful and understanding. They sent us the propane instead of gas. Got it installed and it works great! Would definitely recommend to others.

Instant hot water heater
When we first received the unit we put it up and it had a small leak. When turning the knob where it was leaking it was broken and that is why the leak. I called the company and the person that answered the phone was very laksadaisy and said I would get a part. I sent pictures in an email on what I needed but they claimed they didn’t get. They didn’t ask for my address I had to ask them if they wanted it. I was totally unsure if I was going to get the part. About a week went by and I never received an email with tracking so I called again. Then I was told a different story wanted more info etc. then I never heard from them again so I called Amazon to return item which i didn’t want to do because of pipes etc we would have to re do plumbing for a new one. But since I didn’t have hot water I ordered another different one because I couldn’t get the same one. We took this one down and packaged back up. The day the new heater came I also received the part I needed to fix this one. No notifications nothing just the part showed up. So I unpacked it and had it put back up replaced the part and sent the other back. It worked great for what we need. It is actually I. Our garage we were redoing our bathroom so we made a makeshift shower in garage. Now it will just be used for sink in garage.
