  • Features
  • Includes
  • Condensing design - Operates at up to 96% thermal efficiency which saves money on operating costs compared to a standard 80% efficient gas water heater
  • Helical internal heat exchanger keeps hot combustion gases in the tank longer to extract more heat into the water
  • Construction - Tank and helical heat exchanger are constructed from 444 stainless steel for excellent corrosion resistance without the need for an anode
  • Whisper quiet operation - Ultra quiet blower and burner to minimize noise
  • Power direct vent design - Direct vent using PVC, CPVC or Polypropylene (solid core only) through a sidewall or roof
  • 3 in pipe vents up to 130 ft equivalent
  • Advanced electronic control - Large touch screen display
  • Precise temperature control
  • Advanced water heater status and diagnostics
  • Fully serviceable from the front - Two front access panels expose all serviceable components
  • Modular components are all easily removed
  • Ultra low NOx modulating burner - Enhanced Ultra-low NOx burner complies with SCAQMD Rule 1146.2 and other air quality management districts with similar requirements for NOx emissions of less than 14 ng/J
  • Modulating burner maintains high efficiency operation at lower input rate
  • Side-mounted hot and cold recirculating taps - Polaris can be easily installed with a recirculation system or as part of a combined domestic and space heating system
