A. O. Smith’s Polaris High Efficiency condensing gas water heater
A. O. Smith’s Polaris High Efficiency condensing gas water heater, which operates at a cost-saving thermal efficiency of up to 96%, easily installs and pairs with recirculating systems or domestic space heating systems. Available in 34- and 50-gallon models, it achieves energy efficiency through an enhanced ultra-low NOx modulating gas burner. It features a durable tank and heat exchanger built of corrosion-resistant stainless steel. Compatible with both natural gas and propane, it features a power direct vent design that fits with PVC, CPVC or Polypropylene (solid core only) through a sidewall or roof. It can also be paired with an optional concentric vent kit. Additionally, two front-access panels give contractors simple access to all serviceable components.
