Easy install and the quality of the product is top notch. Unit provides perfect hot water flow and holds the temperature to your selected setting. I wish I didn't have to pay an additional $79 for the larger door that I needed. I am now left with the smaller door originally provided with the unit that I have no use for. What a waste. You should be allowed to choose the door size you need at the ordering process.

Product arrived late, installed item in motorhome, unit didn't work, 😑 reviewed some online blogs, rewired the unit and guess what....... 😀 😀😀!!!
Need I say more???

Using for an off-grid cabin. Follow other reviews' instructions on installing pressure relief valve. Took me a while to figure out all the parts I needed to make it work for a cabin rather than an RV. Lots of trips back and forth from the hardware store, but alas, it works and water is HOT!!! Wife and I use it for showers and washing dishes. Hooks up to a standard grill tank.

NOTE: Use a 100 psi pressure relief valve. NOT the standard 150 PSI valve you commonly find at Lowes or Home Depot. Fogatti sells the right one on Amazon.

12/2022 UPDATE: So, most of the US just went through the deep freeze. During this time, water inside the heater froze causing a part to rupture and water was spraying like crazy inside the unit. I called Fogatti and spoke to an actual person on US soil without a foreign accent. I'd add an extra star for this if i could. I explained the issue and texted them an image of the part that broke and they immediately shipped me out a replacement part! If I were to knock off a start for the part breaking, I'd have to add ot back just because of the customer service. So I still remain at 5 stars for this product. It's actually 6 stars because I spoke to an actual American.

1/2023 UPDATE: Shipping was slow. Very slow. But the part was very easy to replace. While i was waiting for the part to come in, it still made hot water even though it was leaking. Do I still give it a 5 star? Almost. I'd say a 4.9 star.

4/2023 Update:
Not sure if I can recommend this anymore. A few days ago the water heater stopped turning on. I connected a multimeter to the 12V batter and am ready 12V. Tested the wires that go from the battery to the unit' still getting 12V. Tested the wires coming from the unit, going into the remote - 0V. Spoke with customer service and they were very pleasant to work with. Again, it was personnright here in the US and not some foreign call center that you can't understand. So anyways, I spoke with the support tech and he asked me to check a few more things and he determined it may be the board that has gone bad. They're shipping me a new one, and while I do appreciate the good customer service, this thing isn't even a year old and it already needs new parts. I do have a 5 year warranty, so I'll he able to get parts for the next 5 years, but after that, if this thing still keeps breaking, I'm going to have to look for a different unit. If Fogatti's units were as superb as their customer service, this would be a 5/5 stars all day. Dropping to a 3 star. It would be a 1 star as far as reliability, but their customer service is so good it brings them up to a 3. If I get these new parts and I don't have any problems anymore, it'll go back to 5 stars if it stays problem free.

6/2023 Update:
Git the parts, installed and it wasnt working still. Spoke with Fogatti again. We used the multimeter to see the voltage going into the unit: 11.67V. Apparently this was way to low and it won't turn on. My led lights turned on, but not my water heater. I rewired a few things and got it plugged into my solar power station, sure enough, it's turned on with hot water. It wasn't them after all. I need to calll the technician again so I can confirm he was right. 5 stars again. What a rollercoaster lol

2/2024 UPDATE
Since I rewired the water heater to plug directly into the AC solar inverter, I have not had any issues with the unit turning on. Now, if you're using hot water, and suddenly it goes cold and the little black control box starts beeping, turn off the faucet/shower, wait a few seconds, and turn it back on. If it still keeps happening, turn off the faucet/shower, and turn the hot water 3/4 of the way, let it get hot, then turn on all the way. Not sure why I need to do that, but it seems to work.

Easy to install, powered right up and provided consistent temperature hot water. Temp does fluctuate initially, but levels out as water flows. If you're replacing a 2-way tank water heater, make sure the propane circuit 12v is used... Looking forward to saving weight, water, and propane with this unit. The optional large door fits the old opening perfectly, but come on, include the door in the price, make it a selectable option.

Ordered this tankless hot water heater on the advice of our RV tech. He installed it in about an hour and we love it! The quickness of the hot water is amazing and it lasts thru a whole shower! we like how the unit fits in the same place as the old water heater and the control unit is super easy to use.
