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.

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.

Works great, easy to install, BUT I have one problem with the design of this unit that makes absolutely no sense to me. Maybe someone has a solution that I’m not aware of…. The silly wired remote control. I purchased the exterior version in natural gas. Every time I have a power outage at the house, even just a power blink, the unit shuts off. So, I have to get the wired remote control, walk outside to where the unit is mounted, plug in the remote control wire to the bottom of the unit and hit the electronic power button on the remote, unplug the remote and bring it back inside. Everything is great again until the next power blink. This design is really ridiculous. I would need to drill a 3/4” hole somewhere in the house to run the remote to where it would be accessible from inside. There’s a large connector that is hardwired on the remote that is about 3/4” diameter. I don’t want to install the remote inside the house. I want power to be restored automatically to the unit when power is restored to the house. This one issue alone makes me wish I would’ve purchased the Rheem instead of Fogatti.

I have had a Camplux tankless hot water heater for last two years. I had issues with it from day one. Called customer service and they said it was the flow of gas and I needed a new regulator. I decided to buy this hot water heater and it was easy to install and worked like it should from the start. No issue with house regulator like last unit. Very happy with this one. Puts out hot water great.

Really wish I could give this a good review but gotta be real! I bought this unit 9 months ago and have had issues with the water staying hot since day one. The water goes cold approximately 3-5 times during a shower. I have to turn hot water valve off, wait a few minutes then turn it back on and wait for the water to warm to proceed with my shower. After a few minutes water starts getting cold and have to repeat. I have had the propane supply checked - not an issue! Since I installed the unit myself I had a plumber come check it out and all is good with installation and connections! I cannot begin to tell you how aggravating it is to have a head full of soap and have the water turn cold!!! This is very disappointing since all the research I did lead me to believe this would be a good purchase.
