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

I purchased and I nstalled the Shower 8 Plus 55,000 BTU and it fired right up immediately and I had hot water within seconds. It’s a self contained unit that includes the high pressure relief valve. The only external part’s considerations you will need to make are the 1/2”” water inlet and outlets and the 5/8” male gas fitting that is on the back of the unit. My advice is to buy two flexible 1/2” faucet lines that include the 1/4 turn shut off valves on one end and 1/2” shark bite connection on the other end. Simply cut your existing 1/2” PEX lines in the appropriate locations and slip the two new flexible lines on and tight by hand the other end onto the inlet and outlet of the water heater. The shutoff valves will allow you to be able to shut off both water lines in case you need to service and flush the unit without having to shut off water to your entire RV. The electrical is self explanatory and uses a 12V positive and a negative/ground. The included digital controller uses two small wires that connect to the two blue wires on the back of the unit and it doesn’t matter which way you terminate the blue wires to the controller. Make sure you clean the outside mating surfaces before attaching the twelve screws on the outside of your RV and use new butyl tape and/or a good marine sealant to prevent leaks. Inside where your water heater sits screw down a couple pieces of wood snug on each side of the unit to help keep it stable so it won’t tend to shift when your RV is going down the road. That will prevent stress on the outside mating surface during transports. Overall I’m super satisfied with this water heater. I run the temp at 109 degrees and it’s perfect. It runs very quiet. You will have hot water when the electricity is out or if boondocking. Propane is cheaper than electricity and this unit is more efficient than older units and tank water heaters. It’s definitely worth the investment if you are on the fence just know that it’s a high quality product that is well put together with quality parts and materials. Fogatti customer service is better than other companies so that’s another reason to buy from this company. I threw my 100% working Suburban tank water heater straight in the trash bin and didn’t look back. I didn’t shed one tear and I threw it like an angry gorilla! I can now have continuous hot water!

Works well and easy to use!! Easy to install and operates quietly. Quality of the product seems about right for the price. Temperature control works well and the water flow is good. Definitely very useful hot water heater.

During a cross country trip the 10 gal tank style water heater in our RV developed a small leak. Fortunately it leaked to the outside & not inside. Was trying to decide if I wanted to replace it w/ an identical 10 gal or up size to a 12 gal tank style unit. Then I started looking at the tankless style as an alternative & saw the Fogatti 55,000 BTU model. It had good reviews & seemed to have the features I wanted, so I decided to buy it. It's smaller than the original 10 gal tank style heater, i.e. height, width & depth, and it weighs less. I think the height & width are the same as 6 gal tank style heaters. Installation was pretty straight forward once I figured out which wires were the 12VDC power in the RV. Since the Fogatti is smaller than my original heater I had install some filler/trim strips to make the existing opening smaller. It does require some minimum water flow to start so restrictors may have to be removed from some faucets. Also some small on-board 12VDC water pumps may not supply enough flow for the heater to start. Overall it turned out very well. As soon as you turn on a hot water faucet the heater starts & within a several seconds hot water starts to come out. And will continue to come out! Taking a normal length shower is a real pleasure now. I'm glad I decided to go the tankless route vs replacing w/ an identical tank style heater.

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.
