Fundamentals & Application of Outdoor Reset

This session introduces the fundamentals of air‑to‑water heat pumps as they enter the hydronic heating market. The session explains how heat pumps generate usable heating energy, what affects their output, and the core design types used in modern systems. Attendees learn how these units integrate into hydronic applications and how their operation compares to traditional fossil‑fuel systems, giving participants a clear understanding of performance expectations, system configurations, and key differences in design and operation.
