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.

The media could not be loaded. This was very easy to install, saving us lots of money & having continuous hot water is absolutely wonderful! It came fast and on time!

Okay to start off this tankless heater works AMAZING! It’s only been a couple days so far but coming from the previous tankless water heater we were using this one is 100x better. The water pressure is better. The heat control and temperature is better. Almost hotter than a conventional water heater. It saves so much space in our house because it’s one thing we lack in ours, space. It’s great so far. My husband installed it and needed extra materials to complete the installation like a vent pipe which was like $50, $50 in shark bites. It may be a little costly needed materials to complete the installation but if you’re looking to go tankless this would be the way to go. You also need to make sure the heater is strong and powerful enough to support how much water your house will use. We only have kitchen one bathroom and washer. So we aren’t covering a large surface for water usage. You need at least the 90,000 BTU if you want hot water like a conventional water heater. These are great investments if you know what you’re doing or don’t mind paying someone to do but that will make it even more costly. Overall it was a worthy purchase. And quality equipment.

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

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.

It's the first shower I ever took that I didn't have to keep adjusting the hot water! Our house is three adults who are never awake at the same time, so it should have no trouble keeping up with demand. Really, my only immediate criticism is the supplied mounting screws (a couple of panheads just slightly larger than drywall screws). I opted for something a bit more confidence inspiring. Other than that, it's a nice unit. It's as easy to install as any other plumbing device (don't ever let anyone tell you THAT isn't a pain in the *** -- but it's not the machine's fault). Oh, and it's also our first water heater that didn't require two guys and a hand truck. That's always a bonus! Let's just hope it lasts longer than my last tank (which was only four years).

I ordered this unit over a year ago as I know I needed one for our new house.Was installed about a month ago,as now the house is close to finished.This unit comes on,ignites and then goes out.It has produced no hot water.Im told to do test on it,but I know it has been installed properly.Also has a certified propane guy make sure propane flow rate was dead on.Send me another one and I will pack this one back in the box.When you receive it,you can work on your new unit.I don’t feel like I should have to work on something that’s new.

This unit allows me to run two showers at the same time at 120 degrees of hot water without a time limit. It was easy to install, however if you buy the service valves and pressure relief valve be sure to use pipe dope and about three wraps of PTFE tape to prevent leakage if you DIY. I used the same vent pipe that was used by the previous hot water tanks. After you install, allow water to run through the unit until all of the air is out of the water pipes before connecting to AC. Once connected to AC hit the power button on the face of the panel and turn the water on at a facet. you will see the temp come up. then use the up or down arrows to set the temp you want. I hope this helps. I recommend this product.
