## Description

FOGATTI Natural Gas Tankless Water Heater Outdoor - Max 8.1 GPM 180,000 BTU, CSA Certified Compact Design On Demand Instant Hot Water Heater - Instagas Comfort 180S Series - desertcart.com

Review: Great hot water - I got this to replace my 20 year old tank water heater that decided to die on us. My son helped me with the install as I am 71 years old and slightly crippled. The installation was simple and it works great. Of course you need to wait for the hot water but we had to wait with the tank one also. Great technology built into this unit and it seems as though it is going to do the job. A great piece of technology.
Review: MY FOGATTI EXPERIENCE - RUN AWAY. DO NOT PURCHASE - 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 desertcart 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.
