The new Polaris high efficiency condensing gas water heater from A.O. Smith operates at up to 96 percent thermal efficiency, installs easily and pairs with recirculating systems or domestic space heating. Available in 34 and 50-gallon models, an enhanced ultra-low NOx modulating gas burner ensures operation at lower input rates with a durable stainless steel tank and heat exchanger. The power direct vent design is compatible with PVC, CPVC or Polypropylene (solid core only) venting through a sidewall or roof. A concentric vent kit is optional.
