    • Great tankless hot water heater for the money
Material Type: 5.1GPM | 120,000BTU Style: Propane
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. ... show more

    • I like it!
Material Type: 5.1GPM | 120,000BTU Style: Natural Gas
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). ... show more

    • Really fast delivery. Arrived 1 week earlier than expected
Material Type: 4.0GPM | 90,000BTU Style: Propane
I suggest taking the time to remove the 4 screws holding the front panel- 2 on top and 2 on bottom. The fan plug was not plugged in and of course, the system wouldn't fire up until I discovered that it wasn't, and I connected it. I'm suggesting inspecting the wiring etc. inside.

    • So Far, So Good
Material Type: 5.1GPM | 120,000BTU Style: Natural Gas
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. ... show more

    • DO NOT PURCHASE THIS PRODUCT!!!
Material Type: 4.0GPM | 90,000BTU Style: Propane
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 ... show more

I was a little nervous purchasing this heater, because I had never heard of the brand before. But the specs were perfect for my application, and the price was great. I’m happy to say it worked the first time I fired it up and it performs nicely. Honestly, the price is so affordable I may order a second one just to have on hand as a spare. ... show more

    • Works well 6 months later
Material Type: 5.1GPM | 120,000BTU Style: Natural Gas
It easily provides hot water for 2 bathrooms. Comes on quickly. You may have to install a 2 gallon tank inline to avoid the "cold sandwich" . I have installed it with a recirculating pump and it works well. My gas bill dropped dramatically.
