AO Smith GDHE-75LP Vertex 75 Gallon Residential Liquid Propane Water Heater - Power Direct Vent - 6 Year Warranty

VERTEX™ VERSATILE POWER VENT WATER HEATERS

Today’s homes demand more hot water than ever before, and the high-efficiency Vertex™ power vent gas water heater offers unprecedented levels of performance to meet the need. The 50-gallon Vertex delivers more hot water than a standard 75-gallon atmospheric gas water heater. In fact, the fully condensing Vertex design is so advanced, it can deliver “continuous hot water for shower after shower”at a constant flow of over 3 gallons per minute. Yet Vertex is easy to install, with height, diameter and installation requirements similar to standard power vent units
