Material Type: 4.0GPM 90,000BTU


Style: Natural Gas


Features

  • Smaller size and better performanceIt is only 1/4 the size of a 50 gallon tank water heater, yet it produces approximately 4.0 GPM of hot water through 90,000 BTU for both bathroom and kitchen hot water demand. The highly integrated components also provide greater safety from water pressure surges without the need to install an expansion tank.
  • Fast and endless supply of hot waterThe heat exchanger quickly heats the water to a maximum of 149F in a short time, and the hot water is quickly piped through to the shower and tap. No need to wait for the water temperature to heat up slowly like a tank water heater. After that it continues to operate at approximately 4.0 GPM for 40 minutes, which is enough time to produce almost 160 gallons of hot water.
  • Stable and comfortable temperatureBenefiting from the calculation and control of the heating power 1000/s by the chip, the temperature difference of the water can be precisely controlled within 2F.
  • High compatibility and easy installationMost tank water heaters have exhaust vent, water and gas pipe that can be universally used in tankless, requiring only a simple re-layout. If installing a tankless water heater in a new house, its compact size makes it easy to install. Of course, we recommend that all installations are carried out in accordance with local building and plumbing codes by licensed professionals.
  • Excellent quality and serviceCSA certification in the USA and Canada. Superior safety and durability using the world's most advanced technology. FOGATTI provide 5 years warranty on heat exchanger and 2 years warranty on other parts.
  • Note1. Not recommended in excess of 2000 feet above sea level. 2. This tankless gas water heater must be installed in a well-ventilated area. 3. Requires additional purchase of 3-inch diameter exhaust pipe.

  • So Far, So Good
Material Type: 5.1GPM 120,000BTU Style: Natural Gas
I've had this installed for a couple of months now and it is working fine. We had one power outage and I had to go out and touch the touch screen to get it to come back on but other than that it has worked without a hitch. Installing it was easy. It hung on 2 screws with a supplied template, then I added two at the bottom. Literally just connect the incoming cold water, outgoing hot water, and the gas line, and plug in the electrical cord. All were already there as this was a replacement. If you are going from a tank type to this, you might need additional piping or adapters but for me, all the existing pieces connected so there was no looking around for parts or trips to the hardware store. This is an indoor unit so it connects to a flue (or needs a flue) and I did replace the elbow that connected to the flue as my old one was rusty but it was a typical size and was no issue. ... show more

  • Works great
Material Type: 5.1GPM 120,000BTU Style: Natural Gas
Works great and was reasonably priced! We installed this in our new house to save space and ditch the water tank. This heats quick and effectively. Water doesn’t run cold ever. You can set the temperature. No complaints.

  • Really fast delivery. Arrived 1 week earlier than expected
Material Type: 4.0GPM 90,000BTU Style: Propane
I suggest taking the time to remove the 4 screws holding the front panel- 2 on top and 2 on bottom. The fan plug was not plugged in and of course, the system wouldn't fire up until I discovered that it wasn't, and I connected it. I'm suggesting inspecting the wiring etc. inside.

  • Fantastic
Material Type: 5.1GPM 120,000BTU Style: Natural Gas
This was the easiest water heater I have ever installed. You may need to buy a few items that are not included. I recommend getting the clean outs/ pressure relief valve. This install was about 1.25 hours including removing the old. Within 10 seconds I had 130 degree water!

  • DO NOT PURCHASE THIS PRODUCT!!!
Material Type: 4.0GPM 90,000BTU Style: Propane
Purchased this product, delivery was OK. Installed product, no problem. Plugged product in nothing happened. Tried calling Amazon Customer Service, unable to find phone number for customer service. Called Fugatti customer service and was told "We are having problems with this product. Please return product to Amazon and they will replace the product. Finally after an hour of searching I found phone number for amazon. I explained the situation to a non english speaking customer service person. They told me I would have to wait for a refund and I should purchase the same Item gain. Its been over a month since I had to repurchase the item. In the mean time I am out $850.00 waiting for a return. According to the web site they received the Item but have not credited the money. I had to buy another unit because I had installed and made room for this particular unit. In closing: No customer service, Manufacturer is aware ion issues with unit, Amazon is becoming unresponsive and does not care about customer service. Like I said STAY AWAY FROM FUGATTI ... show more

  • Great Value! Save money monthly!
Material Type: 5.1GPM 120,000BTU Style: Natural Gas
The unit was delivered quickly and in sound condition. 2 hour installation, including tool hunts. Saving $38 a month on heating water! Nice and easy to adjust control panel with L.E.D. display. Best part was the price. Cost was HALF the cost of a 40 gallon gas fired water tank! Size is just right. There are six of us. We have three showers, two bathrooms, kitchen with dishwasher, and a clothes washing machine. The unit provides 130 degree endless hot water in about 8 seconds! Extremely recommended for new or replacement for tank models. ... show more

  • Noisy and very slow to start when you turn on the hot water tap
Material Type: 4.0GPM 90,000BTU Style: Propane
We bought this unit basically as a temporary heater until we can fully renovate our house. Having used Bosch and Rinnai tankless heaters in the past, we thought we knew what to expect from even a basic unit like this but we were mistaken. When you turn on the hot water, the unit takes takes 3 seconds to notice and then ignite. That may not sound like a lot, but compared to the other units we've used it's an eternity and it means a lot of wasted water. The unit is also much noisier than we expected. The burner and the exhaust fan make noise while running and while that's to be expected, it is more than the other units we've used. But the real issue is when you turn the hot water off and the unit stops. Other units will keep running the exhaust fan as well, but they just continue at the same speed and you don't really notice. On this unit, the fan speeds up when the unit shuts down and the increase in noise and pitch is jarring. That may not be a problem if you install the unit in a basement or utility room, but it's annoying if installed in an area people use regularly. The instructions also seem to have been somewhat poorly translated from another language. That wasn't an issue for us as we've installed two other tankless units and knew what to expect, but if this is your first install, it could add some challenge. It's not a bad unit, but for not that much more you can get a Rinnai V65iP which will provide more water and do it better. ... show more
