These units are ideal for facilities looking to reduce energy costs and meet ASHRAE 90.1 or Title 24 energy code requirements.

Light duty commercial natural gas water heaters are ideal for small foodservice operations, convenience stores, and low-volume commercial facilities. AO Smith BT and BTF series models in this category combine fast gas recovery with durable tank construction for reliable everyday performance. Available in a variety of BTU inputs and storage capacities, these units are a cost-effective choice for operations with moderate hot water demand.

Lo-NOx commercial natural gas water heaters are designed to meet stringent air quality regulations including California SCAQMD Rule 1146.2 and similar standards in other emissions-restricted regions. AO Smith BTN and Rheem GN series models in this category achieve NOx emissions at or below regulatory limits without sacrificing BTU input or recovery performance. If your facility is located in an area requiring Lo-NOx compliance, these units provide a code-compliant drop-in replacement for standard gas models.

Standard duty commercial natural gas water heaters deliver the increased BTU input and storage capacity needed for restaurants, hotels, laundromats, and medium-sized institutions. This category includes popular models from AO Smith (BTR, BPD) and Rheem (G, GP, GPV, GD) that offer proven reliability and broad parts availability. Both non-ASME and ASME-rated configurations are available to meet your local code requirements.
