How to Unlock Higher HVAC Temperatures with Cascade Systems

Master the transition to electrified heating solutions. Discover how cascade systems offer a sustainable, high temp alternative to traditional boilers, boosting efficiency and tackling retrofit challenges.

Wednesday, June 18th, 2025 | 2pm EST

Air-to-Water Cascade Heat Pump System

As the demand for efficient and versatile commercial heating solutions continues to rise, cascade systems are emerging as an innovative solution designed to meet high-temperature hydronic heating needs of both new and existing buildings. These systems offer a simplified approach to heating and cooling, providing a highly efficient and sustainable alternative to traditional boilers.

Gain a deep understanding of how to design, specify and leverage heat pump chillers advanced by controls to deliver high-temperature heating. Discover how these systems provide a sustainable alternative to noncondensing boilers, reaching higher temperatures, enhancing efficiency while taking into consideration the challenges of retrofits. This session will equip you with the technical knowledge to explain the transition to electrified heating solutions to building owners and clients.

Learning Objectives:

  • Identify different heat sources and types of cascade systems.
  • Understand the advantages of high supply temperatures and the flexible options available for application design.
  • Explore methods for integrating high-temperature hydronic heating systems.
  • Analyze the system's capability to integrate with existing building systems, minimizing disruption and cost.
  • Identify options for heat recovery and auxiliary heat and their benefits.

Attendees qualify for a Certificate of Completion.
