Review: The best on-demand water heater for the money! - 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!
Review: Showers Are Great Now! - 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.

## 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!

## Questions & Answers

**Q: There's a little water coming out from the pipes after unboxing, is this a brand new one?**
A: Mine does that too and it had some corrosion on the back I got it installed and it says a faulty error code 4 saying inlet temperature probe is faulty or the inlet temperature probe is open or shorted. Please check or change the outlet. Temperature probe connection.

**Q: They stated that remote works up to 2 meters away. Is not enough for my aplication . Remote will not work if wires from remote are extended ???**
A: I didn't see the 2 meter limit when I got mine. My application did not require additional wire. Over the length of wire a, keep in mind the power drop off over distance. The wires are very small, like 30ga. maybe a bit larger than that. This means low amp application at 12v. The remote has maybe a meter of wire attached and I could see the power requirements fall off.

**Q: Where does my brown wire coming from my monitor connect too?**
A: I don't remember a brown wire.  Just leave it free and see if the unit  works.

**Q: What psi propane regulator is needed?**
A: Well this is designed to operate off of the low pressure 2nd stage regulator on an RV, so 11" water column or about 1/2 psi.

### ⭐⭐⭐⭐⭐ Amazing unit. Truly
*by T***N on November 30, 2025*

This unit replaced my suburban 6 gallon water heater from the factory. Quick note when installing I needed a few 1/2 per pipes to redo my hot side plumbing it was just a few inches short from the factory. Also you will need to turn on the LP button for eater anytime you want this system to work due to how it gets power from the coach. I see alot of ppl complaining their unit doesn't work when all they have to do is turn on the "propane button" on their electrical panel. This unit works and it works well. It also has a built in pressure regulator so u DO NOT have to go out and buy unnecessary pressure relief valves for this unit despite whatever everyone says online. I have had mine running for over 8 months multiple times a day and have had zero issues. Also you only need the hit water side on you do not need to "mix' the water with the cold like in most showers. Just set your temperature on the thermostat and turn on the hot water side.
