Energy Codes Webinar – 2024 IECC C404.6 Explained: Commercial Hot Water Recirculation & Controls

Join us for a practical deep dive into Section C404.6 of the 2024 International Energy Conservation Code (IECC), covering the latest requirements for service water heating circulation systems and demand-controlled recirculation strategies in commercial buildings. This session will explain how the code is shifting away from continuously operating recirculation systems toward smarter controls designed to reduce energy waste, piping heat loss, and unnecessary pump operation.

The presentation will explore how demand-controlled hot water recirculation systems can help projects improve efficiency while maintaining occupant comfort and reducing water waste. Attendees will also learn how these requirements impact system design, commissioning, inspections, and long-term building performance.

A special guest presenter from AutoHot USA will demonstrate how modern demand-controlled recirculation technologies—such as the Commercial Demand Recirculation Control DC000A—can support compliance with current energy code requirements while improving operational efficiency. The system includes demand-based pump controls, temperature monitoring, and remote monitoring capabilities designed to reduce unnecessary recirculation runtime and water heating energy use.
