    Heat Exchangers in Hydronic & Plumbing Systems
    Thursday, July 29, 2021
    12 noon - 1:30 p.m. CDT  (Note this is an extended edition)

    Heat exchangers are essential components in many hydronic and plumbing applications. A favorite to the webinar series, John Siegenthaler, P.E., will describe different categories of heat exchangers, discuss how to assess their performance, detail their installation, and present several unique applications.

    You'll learn:
    → What is meant by the terms “approach temperature”, “thermal length” and LMTD in the context of heat exchangers?
    → Which flow configuration produces maximum heat transfer rate: concurrent flow, or counterflow?
    → Should heat exchangers made of 316 stainless steel be used in pool heating applications?
    → Why do internal coil heat exchanger require much larger surface area for a given rate of heat transfer compared to brazed plate heat exchangers?

    A seasoned industry leader and passionate teacher, John is eager to share 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 and a regular contributor to industry publications.
