Purpose statement:

The purpose of this webinar is to discuss the available options in electric tankless water heaters, and how to avoid pitfalls when specifying the equipment.

Electrification was a key topic at this year's AHR Expo, and is a growing concern among many states and municipalities who wish to reduce carbon emissions through banning the use of natural gas in commercial buildings. Heat pump water heaters provide a viable way forward for commercial applications, yet there are several potential pitfalls to avoid, so that safety and efficiency can be maximized.

This webinar will discuss the available options in electric tankless water heaters, and how to avoid pitfalls when specifying the equipment.

Sridhar (Sri) Deivasigamani, didn’t set out to create the first commercial tankless on-demand hot water heater. But, after returning home from a 30-hour flight only to find his basement completely flooded from a broken water heater, he knew a worthy challenge when he saw it. After mopping up the basement, the robotics engineer immediately started troubleshooting his water heater. By sunrise, he had the idea for what would become the first on-demand, tankless commercial water heater. This idea would revolutionize the industry and create a safer, cleaner, and more efficient option for building owners. Today, Intellihot boasts several large-scale clients including Levi's® Stadium, home of the San Francisco 49ers, 340 on the Park, Chicago’s second tallest residential building, and Hilton Hotels. The success of Intellihot continues to flourish, with revenue growth in excess of 100 percent year-over-year. The company now employs 100+ people in both Galesburg and Chicago and continues to secure key partnerships nationwide. Prior to founding Intellihot, Sri spent ten years at Caterpillar as a mechanical engineer with a focus on marine engines and control systems. He holds a bachelor’s degree from Manipal Institute of Technology, India, and a master’s degree in Mechanical Engineering from Clemson University. Sri Holds more than 60 Patents, is a member of the IWBI Health equity advisory committee, and is a 2022 Edison award winner.
