CONTINUOUS HOT WATER VERSATILE POWER VENT DESIGNToday’s homes demand more hot water than ever before, and the 94% efficient Nautilus™ power vent gas water heater offers unprecedented levels of performance to meet the need. The 50-gallon Nautilus™ delivers more hot water than a standard 75-gallon atmospheric gas water heater. In fact, the fully condensing Nautilus™ design is so advanced, it can deliver “continuous hot water for shower after shower” at a constant flow of over 3 gpm at a 40° rise. Yet Nautilus™ is easy to install, with height, diameter and installation requirements similar to standard power vent units.
