No Sidewall Penetration

The RV-550 NSP EC is vented through the floor and out of the home with a 2” exhaust pipe. No sidewall penetration (NSP EC) means you don’t have to cut a large opening in the wall.

Ultimate Floor Plan Flexibility

With a smaller footprint and floor venting, the RV-550 NSP EC allows for floor plan flexibility as never before. This can free up cabinet space and provide for less complicated installation.

The Proof is in the Power

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.

More Hot Water. Less Propane.

With higher efficiency and 55,000 BTUs, the RV-550 NSP EC produces more hot water than traditional water heaters. Without a tank to keep hot, many people report that they use up to 50% less propane. Homeowners love the lower operating costs and fewer fill-ups.

Product Features:

  • Endless hot water, on-demand.
  • Designed specifically for RVs, Trailers, Tiny Houses, Cabins, and more.
  • Conveniently vents through the floor without any sidewall penetration.
  • Takes up half the space and weighs one third as much as a ten-gallon tank.
