Tankless, propane-fired or natural gas-fired water heater with full gas modulation and built-in cold weather freeze protection.
The RV-550 EC is a four-season, tankless water heater, installing and fluing just like a tank type water heater, through the sidewall. It comes with a choice of an external aluminum ventilation door in white, black, or unpainted silver (great for Airstream trailers!), for easier color-matching to your exterior.
With 55,000 BTUs—the highest hot water output in the industry—and built-in freeze protection, the RV-550 NSP EC delivers on-demand, continuous hot water.
The heater operates only when the hot water outlet is turned on. The VariFlame control system then keeps the water temperature constant, regardless of the flow rate or incoming water temperature.
