A. O. Smith’s Polaris high-efficiency condensing gas water heater operates at a cost-saving thermal efficiency of up to 96% AFUE and 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. 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 also can be paired with an optional concentric vent kit. Additionally, two front-access panels give contractors simple access to all serviceable components.
