A rapidly developing technology has the potential to revolutionize the way buildings heat water.

Over the past 10–15 years, commercial tankless water heaters have evolved from an obscure and novel option to emerge as a growing mainstream water-heating specification.

Commercial tankless water heaters have the versatility to meet a wide range of load types while offering reliability, energy-efficient performance, and a space-saving footprint. They’re available in a range of capacities and can be combined into larger arrays for water output rates of several hundred gallons per minute. And they don’t waste energy or space keeping a large water tank hot at all hours.

Lodging, healthcare, retail, education, food service, and office represent about 85 percent of all commercial building water-heating energy consumption and 6 percent of the energy use in the entire commercial buildings market.

If architects, engineers, and building owners aren’t paying attention to the energy use of the water-heating systems in their buildings, they’re missing out on an important opportunity for savings, especially in certain building types. Water-heating energy represents a significant 7 percent of all energy use in commercial buildings. But a group of just six building types — lodging, healthcare, retail, education, food service, and office — represents about 85 percent of all commercial building water-heating energy consumption.

This e-book collects our most valuable resources on commercial tankless water heating in a comprehensive format to make it simpler to evaluate whether this exciting technology is right for your project. It provides an overview of tankless technology basics and recent innovations in commercial systems. It includes research and training on why more commercial buildings are going tankless and highlights case studies that illustrate the real-world potential of these systems.

With the data and insights gathered in The Ultimate Guide to Commercial Tankless Water Heating, you’ll be ready to select a water-heating system that maximizes space, efficiency, occupant comfort, and the overall performance of your buildings.
