Fogatti InstaShower Tankless RV Water Heater | 55K-66K BTU | 5 Models

Never run out of hot water again. Fogatti InstaShower tankless heaters bolt into the cutout your old 6- or 10-gallon tank heater left behind, use the existing gas line, and heat water as it flows — with staged combustion and a mixing tank so the temperature stays put when a second faucet opens. Pick by flow: 2.5 GPM for a small trailer, 3.9 GPM for the family fifth wheel.
