Features

  • Gen 3 RV Tankless Water Heater: The 3-generation InstaShower RV water heater now boasts 66,000 BTU and supplies hot water at up to 3.6 GPM. This allows simultaneous use in the RV's bathroom and kitchen with plenty of capacity. Unlike traditional tank water heaters, it provides a stronger flow for single users and eliminates waiting time when multiple people are showering
  • Pushing Performance Limits: FOGATTI RV tankless water heater, equipped with a high-quality heat exchange system, operates smoothly even at altitudes of 9,800 feet. The upgraded NIDEC fan delivers 300Pa of power, ensuring hot water supply even in winds up to 9 on the Beaufort scale
  • Upgraded Alternative to Tank Water Heaters: Fogatti RV water heater is versatile and fits various applications. With a 13"13" opening, it can replace Suburban & Atwood 6-gallon tank water heaters and Girard & Furrion tankless water heaters. To replace a 10-gallon tank water heater, retrofit it with an 18"18" door
  • Unparalleled Bathing Experience: The RV tankless water heater delivers instant hot water at 3.6 GPM with precise temperature control within 1F. The burner adapts to the season: two rows of flames in summer to prevent overheating, and all five rows in winter to ensure warmth. The mixing tank further stabilizes extreme temperatures
  • Save Money and Effort: FOGATTI cares about your convenience and has included a 150 PSI pressure relief valve, so you don't need to purchase and install it separately. Additionally, it comes with a 15"15" door, a 17.64"17.64" trim ring, and an intelligent remote controller that can be used up to 6.6 feet away
  • Safety and Reliability: We have included a filter screen to remove large particles of dust and sand from the water. The product is CSA certified and features multiple safety measures, including a built-in forced exhaust fan on top, stable combustion, automatic gas shut-off in case of flame failure, and anti-freeze protection

  • Must Have for Full time Campers!
Color: IS 9 Pro, Black
Instant hot water! Well worth the price if you’re considering upgrading! Temperature control is easy to use! Has a safety feature to save from burst pipes as long as your RV is plugged in and has gas it will keep your pipes from freezing over in the winter!

  • Better than our old leaky atwood.
Color: IS 9 Pro, White
We replaced our rv water heater with this, and I have really enjoyed it since we installed it about 8 months ago. We had some issues when we had a larger propane tank delivered. The heater kept faulting for propane, but nothing a reset couldn't take care of, and likely at no fault the unit. It was easy to install, we had to purchase a larger door panel separate and it was a good chunk of money, but well worth it ... show more

  • No anode smell

Nice upgrade from tank water heater. No smell of the anode that the tanked heaters have. Easy to winterize.

  • Tankless water heat...well worth the cost!
Color: IS 9 Pro, White
This tankless water heater was installed in a RV in December of 2024 and it's still working well. Water is hot instantly. You can set the temp to whatever you want on the digital pad so you don't have to adjust in the shower. Temp is consistent and will run as long as you need. Makes RV showering something to look forward to. The only issue we've had is periodically the faucet has to be turned off and on 3 times to ignite the hot water. ... show more

  • Sportsmobile now has hot water!

I just finished installing and testing this unit. We are excited to have it in our Sportmobile as the original hot water heater has never worked very well or better said didn’t hardly work at all.

  • Failed motherboard after 5 days
Color: IS 9 Pro, Black
Update, here we are on July 3, 2025 and receiving the E1 fault again. I am updating the rating as well to 1 star, I just wish they had a zero star option. Fair warning please stay away from this product it is absolute junk. I installed this product myself which was not difficult. After 5 days the unit quit heating and displayed a code for the failed ignition. I checked propane which was not the issue. I finally called customer service, the person on the other end sounded like they were reading from a playbook. I had to repeat everything to them at least twice as they were flipping through pages. I explained to them what was going on, I might as well have been speaking a made up language as they had no idea of what I was talking about or describing. They needed me use a voltage meter and send pictures of the readings, which were 0. Which not everyone has a voltage meter, another flaw in their system. They then sent that to their warranty department for verification which took a day. I was told I would receive the replacement within 3 days. It took 8 days b/c they sent it USPS who never gets in a rush to deliver anything. Meanwhile my family was without hot water, which the people at Fogatti could not have been any less compassionate about. I would not purchase this item again. I have heard positive feedback on tankless heaters, but they must have been another brand. ... show more
