Sponsored By:

Number of Credits (if applicable): NATE 8.0, BPI 8.0

Course Description:  Energy efficient central HPWH systems for the multifamily and commercial sector are gaining traction. This session dives deep into the science, technology, design and implementation of successful central HPWH systems. In addition to presenting available commercial products, identifying key design challenges, and exploring the fundamental concepts related to how these efficient systems interact with other building systems, this session will highlight essential maintenance practices, important control considerations and successful case studies.

Audience: This class is intended for engineers, architects, designers, building facility managers, and maintenance personnel.

Learning Objectives:

  • Review of state and local policies that encourage or require all-electric domestic water heating systems
  • Gain an understanding of the economics of central heat pump water heating systems and how they compare with traditional gas and electric resistance water heating systems (considering both first costs and operational costs)
  • Understand the advantages of commercial heat pump water heaters for various building types
  • Analyze key system configurations and design considerations
  • Become familiar with Ecotope’s sizing tool, Ecosizer 1
  • Learn about available equipment packages and the implementation process
  • Review maintenance routines that ensure optimal system performance
