  • February 17, 2022 - Hydronics for Low-Energy & Net-Zero Buildings+

    Hydronics for Low-Energy & Net-Zero Buildings
    Thursday, Feb. 17, 2021
    12 noon - 1:30 p.m. CST


    Combining the availability of water-to-water and low ambient air-to-water heat pumps with global trends for electrification and interest in net-zero buildings presents an unprecedented opportunity for the use of modern hydronics technology that could significantly increase market share while meeting consumer expectations.

    A favorite to the webinar series, John Siegenthaler, P.E., will describe the details of how to craft hydronic systems for modern low energy and net zero buildings. He'll stress simplicity as well as repeatable and resilient approaches that deliver comfort without the complexity and cost that has in some cases stigmatized the use of hydronics in such buildings. Several system templates will be shown and discussed.

    You'll learn:
    → Can modern air-to-water heat pumps serve as “drop in” replacements for fossil-fuel boilers?
    → Can a single heat pump supply space heating, cooling and domestic hot water (DHW)?
    → Is it possible to have more heating zones than cooling zones?
    → What are the advantages of using an existing boiler in combination with a heat pump?
    → Can a single tank supply DHW and act as a space heating buffer?
    → What was the original form of “wireless” room-by-room hydronic zoning?

    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.
