Features

  • Endless water supply without preheatingThe heat exchanger quickly heats the water to a maximum of 140 F within 2 seconds, which is ready for use without waiting for hot water. It can run at approximately 7.5 GPM for 40 minutes, enough to produce almost 300 gallons of hot water. Make a multi-point water supply for the whole house to meet your family's water needs.
  • Precise temperature control and stable temperatureEquipped with a wire controller cord length of 164ft, allowing you to control the water temperature indoors. The burner can be burnt in sections to meet the water temperature demand in the four seasons. Benefiting 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.
  • Compact design for easy installationThe tankless design is 1/4 the size of a 50 gallon tank water heater, making it easy to install. The highly integrated components also provide greater safety from water pressure surges without the need to install an expansion tank.
  • Outdoor installation to save spaceThe product is installed outdoors and does not occupy the living space. The bottom built-in forced DC fan eliminates the influence of external wind. So as to ensure the stability of combustion, achieve safety, energy saving and no pollution. 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 provides 5 years warranty on the heat exchanger and 2 years warranty on other parts.

  • Setup was so easy
Material Type: 5.1GPM 120,000BTU Style: Propane
I was on the fence a long time about which tankless to buy. This unit is amazing I have a large propane tank that feeds my gas stove and now this water heater . The install was seamless I love the controller it comes with also. I have a small cabin 750 square feet I can take a shower while some one is hand washing dishes and this bad boy just keeps delivering. I was gonna grab a different brand but I would 10 out of 10 purchase this brand again. ... show more

  • Great water heater!
Material Type: 5.1GPM 120,000BTU Style: Propane
By mounting on an external wall, all the difficulties of venting are avoided. My use will be seasonal and I will drain it for winter to protect it from freezing. I have an electric tankless water heater in my home that cannot come close to the speed of heating water as this Fogatti. I like everything about it except for the wired remote control. Bluetooth would be so much better than trying to feed a cable through the wall and achieve clean appearance inside. ... show more

  • Horrible, unresponsive customer service & support-Update Below
Material Type: 8.1GPM 180,000BTU Style: Natural Gas
Fogatti customer service and tech support are awful. Amazon's support was AWESOME. We received the item as promised but installed it a couple months after receiving during a remodel project. Once installed, the heater would not operate with low-flow water faucets on sinks. The owners specs stated the item needed .6 gal/min to function. Our sinks are 1 gal/min flow. Heater would only operate when multiple sinks and showers were turned on. Contacted company for support. At first they were responsive. But didn't know how to help us. They didn't know if they have a technician in our area. Requested a replacement, service operator indicated that might not be possible but would submit the request. Then they went silent. We reached out via email for an update. Fogatti's response: "Thanks for reaching out to us. Your request has been updated." We finally resorted to contacting Amazon for help. Within minutes the Amazon customer support helped us with the problem, sent us a replacement water heater and arranged for the return of the defective product. The replacement heater works-but barely. I do not recommend purchasing a Fogatti on-demand water heater-defective products and ineffective customer support. Update 8/1/2023: This is to provide an update to the original review post. On 7/22/2023, Fogotti contacted us by email to follow up to our issue. To remedy the problem, Fogotti offered us a refund of our product. We accepted their offer and thank them for working to find a solution. Our second Fogotti water heater is now installed and is working properly. Thank you, Fogotti, for the total follow through in backing up your product and ensuring we are satisfied. ... show more

  • MY FOGATTI EXPERIENCE - RUN AWAY. DO NOT PURCHASE
Material Type: 8.1GPM 180,000BTU Style: Natural Gas
Update 4 - No response from Fogatti since Sept 29. 43 days? Several times they made promises (in writing) to partially reimburse my installation cost. $200 maximum against the original install ($400) and replacement install ($400) I have lost $600 by originally purchasing their product. Even worse - They Don't Care. UPDATE 3 - NO RESPONSE FROM CUSTOMER NO-SERVICE. LIES ABOUT REIMBURSEMENT FOR INSTALLATION COST. Fogatti will not respond to calls or emails. Case 1234009. After 2 mos of incomprehensible emails Fogatti will not respond after making promises to reimburse $400 installation cost on their defective unit. Had to repack defective unit and return to receive refund which they have completed. WORST EXPERIENCE IN HISTORY OF ANY SELLER ON AMAZON SINCE PRIME PROGRAM BEGAN. Spoke with multiple (12?) Different CS Reps. Emails which repeat previous discussions and impossible to follow directions. RUN AWAY. DO NOT PURCHASE. YOU DO NOT WANT THIS HEADACHE. COMPANY CLEARLY DOES NOT CARE ABOUT CUSTOMER SATISFACTION. UPFATE 2 - RUN . YOU DO NOT WANT TO DEAL WITH THIS COMPANY. Unbelievable struggles with Customer Service. People talking in background. CS Rep cannot find case number. Stumbles through emails. Seriously you Don't want to deal with the headache. Unit I purchased is defective. Shuts off on warm water setting. Ran up to 155 degrees with set point of 115. Request for replacement was going to take 2 weeks. Seriously...Who can wait 2 weeks for hot water? Requested refund. CS Rep had no idea how to process. Furthermore. Another CS Rep advised they would assist in completing my request for $400 fee to install unit. Buy a Rheem and avoid this trouble. Been a week since email and speaking to Customer Service. First off - CR Rep may have been new because he did not understand the problem with heater until approx 15 min of explanation. Problem is simple. If water flow at an appliance - shower valve - is less than 100 percent got - adjusting dial for Warm water - hot water flow shuts off for 5 min. Fogatti wants me to ship unit back and they will then send a replacement. No thank you. Who keeps the packaging after 4 mos? I'll be out of hot water for more than a week - and I'll be paying another $400 to install unit. My advice - stay with a name brand unit that has Techs to trouble shoot. Purchased large outdoor unit in May. Renovating an old farmhouse. Installed by Licenced Plumber. Works fine in 100 percent hot at mixing valve. But temper back hot water to have a "warm" shower and Hot water shuts off. Have contacted Customer Service for assistance. Will update based on resolution. ... show more

  • Easy to intall, great for backyard use or ADU
Material Type: 8.1GPM 180,000BTU Style: Natural Gas
It was quite easy to install with the instructions and watched a quick video online. It’s an outdoor unit that doesn't need vent pipe and is waterproof, that saves much time of installation and make it possible to install in the backyard close to sprinkler water. Just bought a service valve kit and a few gas pipes, connectors, and shutoff valve online and at local stores, then easily hooked it up in less than 30 minutes. One thing to remember thought, make sure to shut off your main gas valve to the house before installation for safety purpose and use gas Teflon tape for sealing the connectors. I also added an extra valve to the preinstalled gas pipe in the back yard, total 3 shutoff valves I used, as you can see in the pictures attached. Currently I only connected it to garden hose water and just a shower head for kids to take shower after swimming and shower pets in the garden, but I actually have a plan to set it up for my ADU (Accessory Dwelling Units) in the coming months. Overall, it’s a great purchase, has worked better than expected in past few weeks. ... show more
