Coffee with Caleffi™

Find It & Fix It

Thursday, May 20, 2021
12 noon-1:30 p.m. CDT


How good are your hydronic system diagnostic skills? Can you spot errors while the design is still conceptual and change the layout to prevent problems? How about uncovering errors after the hardware is installed? Can you come up with a “minimally-invasive” approach to right the wrongs?

A favorite to the series, John Siegenthaler, P.E., will present several problematic hydronic system scenarios and show you what’s wrong based on the "fundamentals" during this extended edition of the webinar. He will also describe how to fix these problems at the design stage and, if necessary, after the installation fails to deliver its expected performance in this extended edition of the webinar series.

You'll learn:
→ Can the supply tees for several secondary circuits all be grouped together along the primary loop?
→ Is it necessary to use a hydraulic separator in systems that have a buffer tank?
→ Can a 1 inch thermostatic mixing valve be used to supply a manifold station that requires 9 gallons per minute flow rate?
→ Does a boiler bypass pipe with its own circulator protect a boiler from sustained flue gas condensation?

A seasoned industry leader and passionate teacher, John shares his over 40 years’ experience in the understanding and proper application of water-based engineering principles with our audience. He is the principal of Appropriate Designs (Holland Patent, N.Y.) and a regular contributor to industry publications.
