  • Very nice water heater, but installation is not for a novice.
Material Type: 7.5GPM 170,000BTU Style: Natural Gas, Black
This water heater is a very nice looking, very straight forward, not many bells and whistles (good thing!) no nonsense water heater. It was much heavier than I thought, but this is my 1st tankless gas water heater. The electric tankless I installed was much smaller and lighter, but I did not have enough power in my circuit breaker box to power a large whole house electric water heater. I am replacing a tank type gas water heater so I thought a natural gas tankless heater would be a good fit. I did learn many things while planning and installing this water heater. Make sure you install a very good and safe vent for the burner! I did a lot of reading and research on this topic and decided that the Z-Vent 3 Inch Horizontal Vent Kit I also found on Amazon would fit the bill for this installation. A valve instal kit is also a must. I installed a scale filter to help minimize the scaling of the heat exchanger as well. So far, the heater is working fantastic and hopefully will for years to come. ... show more

  • Works great
Material Type: 7.5GPM 170,000BTU Style: Natural Gas, Black
I am giving this water heater a 5 star review for several reasons. #1. It was shipped within hours after the order was placed. #2. Installation was so easy. It took less time to install than it did to remove the old water heater. #3. As soon as everything was hooked up, hot water was instant. #4. This water heater takes up less room than the one that was removed. I'm guessing this technology is very similar to cell phones. They just keep getting better over time. ... show more

  • Bad tech support and short lifespan
Material Type: 7.5GPM 170,000BTU Style: Natural Gas, Black
Do not buy this product. Not only did it only last for less than one year, when we had a local technician come out we were told it would be almost impossible to get parts as this product is made in china. This unit worked great for 8 months and then started acting up with E1 error codes. The tech support was useless and never was able to isolate the problem. In the end we ended up replacing it with a regular gas water heater that is more efficient than this pos. ... show more

  • Workd good after figuring out the problem
Material Type: 7.5GPM 170,000BTU Style: Propane, White
I installed the unit and had no hot water. After watching a couple of online videos and reaing the manual. I figured out the igniter wire had came disconnected during shipping. Connected the wire and works great. We will see about durability. I'm only feeding 3 sources now. I have 3 more discharge points to connect. I will update later. ... show more

  • Igniter fails prematurely
Material Type: 7.5GPM 170,000BTU Style: Natural Gas, Black
This has been a very good water heater, when it does not fault out with an E1 code. This code is an ignition fault and will not heat the water. After many emails, and much time opening up the cover and inspecting the wiring, etc, I have finally managed to diagnose this on my own. It turns out the igniter is showing extreme signs of wear and will only intermittently ignite. This is a spark igniter similar to what is used on a gas grill. I am now trying to locate parts, but this seems to be an impossible task. If anyone knows of where to get Fogatti parts, please send me a note. ... show more
