Features
- High-Altitude Ready: Flawless RV Hot Water Heater to 9,800 Ft! The high altitude suitability mode allows the machine to run smoothly even when driving the caravan to the high Denver plateau at 9,800 feet. Staged combustion technology, which controls the amount of flame in summer, prevents the water from getting too hot and saves the limited propane gas available for caravan travel
- All RV water heaters can be replaced: The Fogatti RV water heater have a wide range of applications. The opening is 13 x 13 inches and the door is 15 x 15 inches. It can replace Suburban and Atwood's 6 gallons tank water heaters, as well as Girard and Furrion's tankless water heaters. If you previously used a 10 gallons tank water heater, it would need to be retrofitted with an 18 x 18 inches door
- Never Run Out: Our RV Tankless Water Heater Lasts 40+ Min (vs. 8 Min Tanks). With 55,000 BTU of power, it can produce a maximum of 2.9 GPM of hot water. Some tank heaters can only store up to 6-10 gallons of hot water and run out of hot water in 5-8 minutes, whereas our hot water supply lasts over 40 minutes
- Shower Bliss for RVs: Tankless, Propane, No Cold Surprises. RV tankless water heaters are taking off. Tankless water heaters are better than tanked water heaters for continuous showering of multiple people. There is no need to waste 20-30 minutes waiting for hot water in the middle of the shower, so you can enjoy hot water at all times. It uses propane for heating, so there is no need to worry about running out of power in your caravan
- All-Inclusive RV Water Heater: Built-in Valve + 15" Door + 2m Remote! Fogatti has always thought of you, with a pressure relief valve built into the product, so you don't have to buy and install it separately. And it also comes with a 15 x 15 inches door and an intelligent remote controller up to 2 meters long
- Safety and reliability; The product is CSA certified and has multiple protection features such as a built-in forced exhaust fan on top, stable combustion, automatic gas shut-off for accidental flame failure and anti-freeze

Took about 4 hrs working by myself to remove my old 6 gal tank water heater and totally install this tankless heater. It heats the water up a lot faster than I thought it would. Hot water now that’ll run directly off the solar system on my travel trailer. Amazing, I live in western North Carolina after the hurricane my wife’s biggest concern was hot water, no more. That’s fixed now.

Installation was straightforward and the controls are easy to understand. Thankfully, I had easy rear access for my installation to make all of the plumbing connections. Performance - worked beautifully! Heated the water to temperature very quickly and was not very loud doing it. Full water flow through the unit to the kitchen faucet and shower. We're on a permanent site so no worries for long showers for us! Winterizing was straight forward with the pressure relief valve being located right at the rear of the unit. Going to de-winterize the camper soon so time will tell if I was able to get all the water passages blown out or not! Looking forward for many years of service for this unit.

My wife and I replaced our atwood 6 gallon hot water heater on our winnebago RV. Being that it is a motorhome, there was an added coolant line intended to heat water while driving...that had to be bypassed prior to install (nothing on the manufacturer but keep in mind if you have a motorhome) Install was very simple and only required a couple of 1/2" PEX to 1/2" NPT female fittings, and moving the 3/8" propane line brackets slightly. Writing this after using for almost 3 months and it is a blessing! Hot showers as long as you want, great heat to flow ratio and it's hot almost as soon as the pipe water is circulated, plus about 10 seconds. As long as you're connected to city water, this is the ticket! We have also saved a LOT of propane not wasting it to keep a tank hot all day/night. Only using the propane on demand has made 40lbs of propane last what seems like a year, whereas before it lasted 45 days at most. The built on control panel allows you to change top end temp and auto shuts down if there is a pilot flame out, making it safer and more reliable. If you live on tanks often, you may be disappointed with how much water you'll waste to get hot water. It doesn't stay on well with the HW valve less than half flow, meaning you need higher flow just to keep it on. Turning off the valve or shower head to save water doesn't work well either because as soon as it senses less flow, it switches off and begins cool down. Not a water saver, but a propane saver for sure.

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. 11/2024 Update: Still no problems since the last update. Wiring this thing to be able to plug directly into a standard wall outlet was the ticket. Significantly less issues with water suddenly going cold. Still happens though, but the trick I used in my previous update still works. Heading into winter now so we'll see if the pipe freezes and explodes again. 3/2025 Update: Coming out of winter. Pipes did not freeze. FYI, this unit can supply 3 fixtures with a bit of decreased performance. Built an addition to our cabin, will need to upgrade to a larger unit or get a second unit.
