A.O. Smith Vertex™ Power Vent Water Heater (Model GPHE-50)

GPHE Vertex Water Heater

  • 90% Thermal Efficiency
  • Endless Hot Water
  • Versatile Power Vent Design

Today’s homes demand more hot water than ever before, and the 90% efficient 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”…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.

Helical Internal Heat Exchanger

  • Spiral heat exchanger keeps hot combustion gases in the tank longer to lengthen the heat transfer cycle
  • Positioned in the center of the tank for more even heat distribution
  • Operates at 90% thermal efficiency, which saves money on operating costs compared to a standard 78% efficient gas water heater

Power Vent Design

  • Combined vertical and horizontal runs terminating through an outside wall. Vents using PVC, CPVC, ABS or polypropylene pipe. Canadian installations require ULC S636 approved pipe for venting.
  • 2” pipe, vents up to 25 equivalent feet
  • 3” pipe, vents up to 65 equivalent feet
  • 4” pipe, vents up to 128 equivalent feet

Modular Blower

  • Equipped with 120 volt, 60 Hz electrical system (rating 5 amps or less), 6-foot cord with standard 3-prong connector
  • 2” PVC pipe, elbows and condensate drain supplied to connect heat exchanger outlet to blower
  • PVC Vent Attenuation Assembly (VAA) supplied

Side-Mounted Hot and Cold Recirculating Taps

  • Allows Vertex to be installed as part of combination space heating/water heating applications or any system requiring a recirculating hot water loop, including radiant floor heating.

Intelli-Vent™** Gas Control

  • Equipped with nearly indestructible silicon nitride hot surface ignitor — no standing pilot
  • Advanced electronics for more precise control of water temperature and easy to understand system diagnostics
