Heavy duty commercial electric water heaters are built for the most demanding environments including large hotels, hospitals, and industrial facilities requiring ASME-certified pressure vessels. The AO Smith DSE series exemplifies this category with robust tank construction, multiple heavy-gauge heating elements, and compliance with the ASME Boiler and Pressure Vessel Code. These units are designed to deliver high-volume hot water reliably around the clock.

Light duty commercial electric water heaters are engineered for lower-demand applications such as office break rooms, small cafés, hair salons, and convenience stores. AO Smith DEN, DEL, and Rheem ELD/ELDS models in this category deliver reliable hot water with energy-efficient operation and easy installation. These units are available in a range of gallon capacities and voltage configurations to match your specific usage requirements.

Medium duty commercial electric water heaters provide increased recovery rates and larger storage capacities suited for restaurants, motels, and mid-size facilities. The AO Smith DRE and DVE series, along with Rheem ES and E models, are engineered for consistent performance under moderate continuous demand. These heaters offer multiple element configurations and a variety of voltage and phase options to fit your electrical infrastructure.

The Rheem PowerPack is a modular commercial electric water heater system designed to provide large-volume hot water capacity for hotels, hospitals, universities, and other high-demand facilities. By combining multiple heating modules in a space-efficient configuration, the PowerPack delivers the hot water output of a much larger conventional unit while allowing for staged maintenance and reduced downtime. Wallingford Sales can help you size and configure the right PowerPack system for your facility's requirements.
