Description
- 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. HydroShield-Tech adds reinforced weather resistance, ensuring stormproof reliability and extended durability. The upgraded fan delivers 300Pa of power, ensuring hot water supply even in winds up to 9 on the Beaufort scale.
- Eco Friendly Performance: The InstaShower Ultra's 0.5 GPM ultra-low flow startup technology supports lower energy consumption to match low flow usage scenarios, conserving resources and making it the ultimate solution for sustainable RV adventures.
- 66,000 Highest BTU: InstaShower Ultra 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.
- Mastering Temperature Stability: 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.
