Commercial Sizing Help?

Yes, tankless water heaters are excellent for commercial applications when properly sized. A. O. Smith commercial tankless models deliver up to 199,000 BTU input with ENERGY STAR® certification and can be configured in rack systems for higher capacity. These units provide continuous hot water on demand, making them ideal for restaurants, hotels, schools, and businesses with consistent hot water needs. Commercial tankless water heaters offer space-saving installation, energy efficiency by heating water only when needed, and the ability to link multiple units together for high flow rate applications.

Sizing a commercial tankless water heater requires calculating your peak hot water demand in gallons per hour based on your business type and usage. Consider the number of fixtures (sinks, dishwashers, showers, laundry machines), operating hours, peak usage times, and incoming cold water temperature. You'll need to determine both flow rate and recovery rate to meet demand during busy periods. A. O. Smith's Pro-Size Tool walks you through your facility's water heating needs and recommends the right commercial tankless product or rack system configuration.

Installation costs vary widely depending on your application, facility requirements, and system configuration. Factors include the number of units needed, rack system complexity, venting requirements, electrical or gas line upgrades, and local labor rates. Multi-unit rack systems and higher BTU capacity installations cost more than single-unit applications. For an accurate estimate based on your business needs, find a local plumbing professional who can assess your facility and provide a detailed quote.

Commercial tankless water heaters are built for high-demand continuous use with more powerful heat exchangers, higher BTU capacity (up to 199,000+ BTU), and components designed for constant operation. They reach higher temperature settings and offer greater durability under heavy daily loads. Residential models are designed for smaller household needs with lower BTU ratings and intermittent usage patterns. Commercial units also offer rack system configurations allowing multiple units to work together for extremely high flow rates that single residential units cannot provide.
