Our commercial electric water heater selection covers every duty rating, from light-duty point-of-use models to heavy-duty ASME-rated tanks for the most demanding applications. Featuring top-tier brands including AO Smith and Rheem, these units offer precise thermostat control, durable construction, and long service life. Electric models are ideal where gas lines are unavailable or where installation simplicity is a priority.

Wallingford Sales offers a comprehensive selection of commercial natural gas water heaters covering every performance tier, from light duty models for small businesses to extreme high-input units for large industrial facilities. Our inventory features trusted brands including AO Smith and Rheem in standard efficiency, Lo-NOx, and high-efficiency configurations to meet local emissions regulations and energy code requirements. Fast recovery rates and durable construction make gas-fired units the preferred choice for high-demand commercial and institutional applications.

Wallingford Sales offers a complete selection of commercial propane (LP) water heaters for facilities without natural gas service. Available in light duty, standard duty, high efficiency, and extreme high input configurations, our propane models from AO Smith and Rheem deliver the same reliable performance as their natural gas counterparts but are factory-converted and calibrated for LP fuel. ASME and non-ASME versions are available across most model lines.

Commercial tankless water heaters provide on-demand hot water without the standby heat losses associated with traditional storage tank models, making them an energy-efficient choice for a wide range of commercial and institutional applications. Wallingford Sales carries an extensive selection of tankless heaters including electric models from Chronomite and Eemax, and natural gas and propane units from leading manufacturers. Whether you need a single-point-of-use unit or a high-capacity multi-unit commercial system, we have the right solution.

Commercial water heater booster systems raise incoming hot water temperature to the 180°F final-rinse requirement for commercial dishwashers and other high-temperature sanitizing applications. Wallingford Sales offers electric and natural gas booster models from AO Smith designed for reliable, continuous operation in restaurants, cafeterias, healthcare facilities, and institutional kitchens. Our booster heaters are sized to match a wide range of dishwasher flow rate requirements.

Commercial water heater storage tanks provide supplemental hot water capacity for large facilities where a single water heater cannot meet peak demand on its own. Wallingford Sales carries jacketed, insulated, and unjacketed storage tanks from AO Smith and Rheem in a wide range of gallon capacities for vertical and horizontal installation. These tanks are designed for use with indirect water heating systems and can be paired with most commercial water heater models for a complete system solution.
