Lowering Water Temperature in Existing Hydronic Systems 
Thursday, July 25
12 noon - 1:00 p.m. CDT

As the North American market for high-efficiency boilers and renewable energy heat sources continues to expand, there’s increasing need 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. He will also show practical methods of modifying them for low-temperature operation and expanded capabilities such as room-by-room zoning.

You'll learn:
→ Is it practical to operate fin-tube baseboard at 120 ºF water temperature?
→ Should you add heat emitters to an existing series baseboard circuit?
→ What needs to be checked prior to using older cast-iron radiators in a modified hydronic system?
→ How can an older single zone distribution system be converted to room-by-room zoning?
→ Do all supplemental heat emitters added to an existing system have to be the same type?

A seasoned industry leader and passionate teacher, John 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.

Troubleshooting Hot Water Recirculation: A Case Study
Thursday, Aug. 22, 2019
12 noon - 1:00 p.m. CDT

Have you ever received a call from a large multi-family complex with the residents complaining about instantaneous domestic hot water availability? Worse yet, have you been called out to investigate and repair pinhole leaks in a building's DHW circulation return system? New to the series, Mark Eatherton is eager to share how he resolved a 40-year old recirculation problem that threatened to shutdown a large, multi-family subsidized housing project due to a lack of readily available DHW in the building.

You'll learn:
→ Where do I begin when balancing an existing system? What are the priorities?
→ What are the biggest challenges in correcting a poorly functioning system?
→ How do I size and apply thermal balancing valves in retrofit applications?

There aren’t many situations that Mark hasn’t encountered and resolved in his 40+ year career in the industry. He is a licensed Master Plumber (Colo.) and a licensed Master Mechanical Contractor under the ICC auspices. Did we mention that he loves to teach, write and educate and has been doing so for over 25 years? An avid supporter of the Radiant Professionals Alliance, he is employed by Advanced Hydronics, Inc. where he is responsible for designing, managing, training and troubleshooting tough plumbing and hydronic related problems.
