The new Seattle Energy Code requires heat pump water heaters for hotel and multifamily buildings, and City Council is considering extending this requirement to other commercial buildings as well. This webinar will look at the pros and cons of the available system types, examining the cost, efficiency, space requirements, code compliance and more for each system. We will look at the balance between heat pump capacity and storage tank size.

You will hear the code requirements and several engineering solutions described, with advice and examples from experienced local subcontractors and equipment suppliers.

Learning Objectives

Attendees will learn to:

  1. Reduce energy use and carbon emissions by optimizing water heating systems
  2. Design code-compliant water heating systems
  3. Select technology appropriate for the size and type of building
  4. Reduce hot water circulation losses and pumping energy
  5. Plan for heat pump water heating space requirements
