Coffee with Caleffi™: Lowering Water Temperature in Existing Hydronic Systems

caleffi july 2019

As the North American market for high-efficiency boilers and renewable energy heat sources continues to expand, there are increasing needs for hydronic delivery systems that complement those heat sources. In new construction situations, there are ample methods and materials for creating low-temperature hydronic heating distribution systems. However, tens of thousands of existing buildings have “high-temperature” distribution systems that severely limit the potential of these contemporary heat sources. John Siegenthaler, P.E.will present techniques to evaluate those existing systems for potential operation at significantly lower water temperatures at the next Coffee with Caleffi™ webinar on Thursday, July 25 at 12 noon CDT.

A seasoned industry leader, passionate teacher and favorite guest speaker of the webinar series, Siegenthaler shares his over 35 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.

The one-hour educational webinars are freeand are intended for contractors, designers and wholesalers. A Certificate of Attendance is emailed to attendees following the event for continuing education audits. Please visit our website at for schedule details and registration.
