The FOGATTI 66,000 BTU Tankless RV water heater easily replaces RV water heaters from Suburban, Atwood and Dometic. It has staged combustion technology, which controls the amount of flame in summer, prevents the water from getting too hot and saves the limited propane gas available for caravan travel. It is CSA certified and has multiple protection features with a built-in forced exhaust fan on top, stable combustion, automatic gas shut-off for accidental flame failure and anti-freeze. The high-quality stainless steel construction helps it withstand rough RV travel. The heater also comes with a wire controller and smart digital display for convenience.
