Course description

This is a free lecture presented by hydronics expert John Siegenthaler. The future of hydronic heating is low water temperature. This is necessary to optimize the performance of modern heat sources such as condensing boilers, heat pumps, and solar thermal collectors. With proper design, you can create systems that require supply water temperatures no higher than 120°F under design load conditions. In this lecture, you will learn:

  • Why low operating temperatures are important in modern hydronic systems
  • The differences between high-mass and low-mass heat emitters
  • Details of the operation of micro-fan equipped panel radiators
  • How to describe the construction of radiant wall and ceiling panels
  • How to describe a home-run distribution system serving several panel radiators
  • Why low temperature heat emitters are critical in systems with renewable energy heat sources
  • The best distribution piping system to use with low temperature emitters
  • Simple and reliable methods for room-by-room temperature control
  • Why low temperature emitters are critical in systems using thermal storage

I took the course in 2021, so the presentation is about six years old. But I found it current, interesting, and most helpful. The presenter has extensive experience and knowledge in the subject and is an excellent teacher.
