Features

  • Instant Hot Water: Fogatti InstaShower 8Plus delivers 2.9 gallons of hot water per minute and 55,000 BTU heat output, ideal for meeting the needs of a busy RV family. The tankless feature saves energy by only engaging the burners when water is needed, be it for a hot shower, clean dishes, or washing hands. Compared with tank water heater, there is no need to wait for the water to heat up and replace anode rods frequently
  • Unique and Distinctive Features: The high-altitude suitability mode allows the machine to run smoothly even when driving the RV at 9,800 feet. Staged combustion technology maintains consistent temperatures by reducing cold spots and scalding. Enjoy endless hot water by adding cold water to reach your desired temperature
  • Replaces all RV Water Heaters: There are three door options with two colors, black and white, which can easily refit RV electric water heater and RV tankless water heater. 15" x 15", 15" x 18", or 18" x 18" is required for installation, sold separately
  • Upgraded Version: Fogatti has always thought of you, built into a high-quality 150 PSI pressure relief valve of the product, so you don't have to buy and install it separately. A 6.6ft-long intelligent remote controller allows easy adjustments of water temperature from 95F to 123F
  • Safety and Reliability: The tankless RV water heater is CSA certified and has multiple protection features such as a built-in forced exhaust fan on top, stable combustion and automatic gas shut-off for accidental flame failure. Antifreeze protection keeps the system functional even in cold weather

  • Solid product, good price and easy install
Style: InstaShower 7
This is the second one of these I've bought for two different RVs. Both worked great. Yes, it does take a few seconds to get hot, but then it stays at the correct temp you want. If you want a fairly easy install with continuous hot water, this works great and is a fair price.

  • A Must Have!
Style: InstaShower 7
I'll never own another RV without one of these. Camping with my wife and two daughters meant no warm showers for me. Problem solved. This tankless heater was extremely easy to install, It fit in the existing hole from the old unit. Included directions were easy to follow with no issues. After connecting the wiring, plumbing and gas it worked flawlessly. It doesn't come with the door, but the suggested version was a good fit. This heater is worth every penny, wish I had ordered it sooner. ... show more

  • It’s garbage constantly E1 code no hot water. Don’t buy it.
Style: InstaShower 7
I bought the Fogerty hot water system in June. I hate it. I constantly get the E1 code. I can never take a hot shower. I do not have hot water. It doesn’t work. It’s the worst thing I did. I wish I could go back to a tank hot water system, but I cut everything out and replaced it with this one thinking it was the better alternative six months almost and no hot showers. No hot water for dishes. I have to boil my water to bathe and I have to boil my water to do my dishes. I hate it. ... show more

  • Hot water
Style: Door 18"x18",White
Order was delivered as promised. Came with plenty of instlation screws. Hot water heater seems to work great the only drawback is the antifreeze function seems to be turning on too early. I think fogatti has it set at 45 degrees.

  • Best Upgrade!!!

Best camper upgrade. Worth every penny. Easier to connect and plumb than a tank water heater. Never run out of hot water!

  • Works great
Style: InstaShower 7
I honestly dont know what I did before getting this. I love my tankless hotwater heater. The only problem is have found is it has a 20 minute safety so if you take a longer one just turn off hot water and back on. Other than that I love it.
