  • Great Texh Support
Material Type: 8.1GPM 180,000BTU Style: Propane
Easy to install. Immediately made great hit water but it was too hot. I contacted Fogatti support using the chat on the webpage and before I knew it I had received a text from one of their support Techs (Adam). He gave me instructions and after a couple of tries we solved the problem. The guy followed up with texts to make sure things were working until all was good. Best tech support I’ve had. Was expecting the worst but got the best. ... show more

  • Been working great!
Material Type: 5.1GPM 120,000BTU Style: Propane
This heater has been working great for a few weeks now. In case anyone is wondering I contacted customer service and asked if it would run on a 20# propane tank. They got back to me right away and said it would contrary to some of the Q&A responses. It’s been working great on both 20# & 30# tanks for me. For reference We have a small 1bd & 1 bath park model home in Palm Springs so in the winter my incoming water temperature is in the 60’s. Just remember you still need to “push” the cold water out of your line between the heater and outlet so it’s not “instant”, just like a regular hot water tank. ... 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

  • 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

  • It works! Using for my master bathroom.
Material Type: 6.3GPM 145,000BTU Style: Natural Gas
I ran new water lines to replace my old galvanized, and new gas line. I tested it today and it's working great! Still need to add a line for the blowout valve and put some clamps to square up the pex.... I was pleasantly surprised that it worked with no issues after reading some of the comments.

  • 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
