With a 13 x 13 inch 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 x 18 inch door.
- Unparalleled Bathing Experience: The RV tankless water heater delivers instant hot water at 3.6 GPM with precise temperature control within ±1℉. 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 x 15-inch door, a 17.64 x 17.64-inch 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.
- 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.
- 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.
