Coffee with Caleffi

Hydronic Zoning - from Design to Installation
Thursday, August 28, 2025
12:00 - 1:00pm CDT

Technical Content Level: Intermediate

The ability to easily divide a heating or cooling distribution system into zones has always been a benefit of hydronics technology. The August Coffee with Caleffi will feature two “seasoned” hydronic pros: Bob (Hot Rod) Rohr and John (Siggy) Siegenthaler, discussing hydronic zoning techniques from the standpoints of both design and practical installation. They’ll discuss the following topics:

→ The strengths and limitations of zoning with circulators and valves
→ The attributes of electric zone valves and non-electric thermostatic devices
→ Practical installation and service tips and tricks from the field
→ Modern zoning techniques to tailor your systems to the needs of each project

John (Siggy) Siegenthaler, P.E. is an industry expert and passionate teacher, eager to share his 40+ years of experience in the understanding and proper application of water-based engineering principles with our audience. He is a Carlson-Holohan Industry Award of Excellence honoree and a regular contributor to industry publications.

Bob (Hot Rod) Rohr has traveled in his training role with Caleffi from Fairbanks, Alaska to Guantanamo Bay (to commission solar panels) in his 40+ years of experience. He has a knack for making hydronics relatable as a writer and installer. Bob is a Carlson-Holohan Industry Award of Excellence honoree.
