    Resulting from an ultra high 96% Thermal Efficiency rating
  • High system efficiency even during low load conditions:
    The modulating burner operates at a 3 to 1 turndown ratio, matching fuel consumption to demand
  • Improved component life and reliability:
    Modulation, along with thermal mass, eliminates the short cycling effect, which conserves energy and improves component reliability
  • Appropriate for both residential and commercial applications:
    Available in three gallon sizes (ranging from 55 to 119 gallons) and three BTU inputs (ranging from 100,000 to 199,000 BTUs)
  • Low standby losses:
    The tank loses only ½ degree Fahrenheit per hour when the burner is off, thanks to 2” of environmentally safe foam insulation
  • Virtually maintenance free operation:
    The robust material and sophisticated design of the heat exchanger minimize lime and scale buildup, eliminating blockage risks
  • Incredible system flexibility:
    Built-in auxiliary taps provide connections to air handlers, radiant heating, or supplemental storage tanks
  • Optimum serviceability:
    A removable front cover provides service technicians easy access to components
  • Quality construction:
    an extremely durable cupronickel and stainless steel heat exchanger boasts excellent heat transfer properties and resists corrosion, while the robust 316L stainless steel tank eliminates the need for anode rods
  • Excellent venting options:
    uses inexpensive, easy-to-install PVC or CPVC pipe, with vent lines up to 85 feet total equivalent length
  • Self-diagnostic electronic control:
    displays digital readouts for water temperature, set point and differential
