Thursday, February 19, 2026
12:00 - 1:00PM CST
Technical Content Level: Intermediate
Join us for the first edition of Coffee with Caleffi in 2026, featuring hydronics expert John Siegenthaler, P.E. He will discuss the benefits of zoning hydronic heating and cooling systems. Proper zoning allows the right amount of heating or cooling to be delivered exactly where and when it’s needed in a building. Modern hydronics technology offers several approaches to zoning. They involve different hardware, different means of control, and different piping arrangements. This webinar will provide a survey of modern hydronic zoning techniques, and discuss circumstances where each of several approaches is ideal.
→ Understand the basic operation and selection of electrically-operated zone valves.
→ Understand how non-electric thermostatic valves can be used for zoning.
→ Learn about differential pressure control in valve-based zoned system.
→ Appreciate several piping details to improve the performance of zoned systems.
Siegenthaler is a seasoned industry leader and passionate teacher, eager to share his over 40 years of experience in the understanding and proper application of water-based engineering principles with our audience. He is the principal of Appropriate Designs and a regular contributor to industry publications.
