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

  • Better than expected!!
Color: IS 9 Pro, Black
Easy to install, works exactly as promised. Endlessly provides a perfect shower!!

  • 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

  • Works great, do need some knowledge to install
NICE, LONG, HOT SHOWERS IN MY RV - YAAAAAAAAAAS!!!!! This unit definitely does what it's designed to. I've had no issues with it heating the water up, even in the middle of winter. The install was fairly simple, except the wiring. If you haven't messed with RV wiring, there is no "standard" color code and many times the circuits in a single trailer dont follow the same pattern as others. For example, I have circuits where black is ground and others where white is ground. I used an ohm meter to determine this particular circuit. Also, don't forget, RVs are similar to 12v car systems in that they use a negative ground. My unit did have a dead controller on arrival. Amazon made me jump through a bunch of hoops to get in touch with the seller, including a phone call with foreign tech support to tell them everything I'd already told someone in a chat which was annoying. Ince I got in touch directly, the seller was prompt to respond and to send me a new controller. ... show more

  • No more cold showers!
Color: IS 9 Pro, Black
We've been full-time for two years now. We kept going back-and-forth about getting a tankless water heater because of the cost. Unfortunately, the decision was made for us when our water heater leaked and flooded our basement storage area. We did some research and a few friends of ours bought this exact unit. It is fabulous!!! We don't run out of hot water and we can finally shower together again. One of the best parts is that you can have an everything shower (girls if you know you know). My husband said it was super easy to install as well. ... show more

  • 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

  • Operator Error
Color: IS 9 Pro, Black
I installed it following the directions but the controller didn’t activate the water heater so I assumed the controller was defective. I purchased a new controller and got it to work. The directions don’t tell you that you have to turn the hot water on to activate the controller. So I have an extra controller! ... show more

  • Beats Expectations
Color: IS 9 Pro, Black
One of the first items I have purchased in last 10 years that works better than advertised. Took 30 min to remove Girard unit and install this one. Only request would be to get water hotter than 123* The digital temp readout is also nice feature
