Joining the AO Smith Vertex Power Direct Vent Water Heater family is the new 75-gallon model. The GDHE-75 offers the same high level of performance as its 50-gallon sibling, and you can find both on the site.
The GDHE-75, with its 96% thermal efficiency rating, is designed to specifically generate a constant flow of 4 gallons per minute, meaning continuous hot water in your home. It comes with a helical coil heat exchanger which keeps hot combustion gases in the tank longer to lengthen the heat transfer cycle. Positioned centrally in the tank and with its 96% thermal efficiency, you will save money on operating costs compared with a standard 80% efficiency gas water heater.
The GDHE-75 also comes with a large LCD display giving you precise temperature control and the ability to check diagnostics, and it can be vented vertically thru-the-roof or horizontally thru-the-wall with inexpensive PVC, CPVC , ABS or polypropylene pipe for intake and exhaust. The side-mounted hot and cold recirculating taps allows the Vertex models to be installed as part of combination space heating/water heating applications.
The ultra-low NOx gas burner meets low NOx emission requirements, and the Vertex family comes with a 6-year limited tank and parts warranty.
