Quantifying Energy Savings from Heat Pump Water Heaters in Cold Climate Homes

Heat pump water heaters (HPWHs) are some of the most efficient water heaters on the market, with a potential to save more than 50% of electric water heating energy. While they have been gaining significant market traction in the southern US, their ability to effectively save energy in a cold climate, where conditioned basements exist, had not been examined. 

Senior Research Engineer Ben Schoenbauer will cover the findings from CEE's recent study and app development, touching on how these mechanical systems affect homes from a whole house perspective. The presentation will publicly debut two new web-based calculator apps that estimate electric savings due to these installations at both the single-house level and the electric utility level.

Target Audience

  • Utility program managers
  • Home builders and contractors
  • Residential architects
  • Mechanical equipment manufacturers

Webinar Outline

  • Recent market uptake of this product type in cold climate settings
  • The magnitude of water energy savings that can be expected in cold climate homes and the house conditions that affect the energy savings
  • Introduction to the web-based calculators tools

GBCI Learning Objectives

  1. The best installation practices for high performance electric water heaters.
  2. The heat transfer impacts of heat pump appliances.
  3. What are domestic water heating loads and what household characteristics can be used to estimate them?
  4. What are the electric peak load impacts of different water heating technologies and what consequences these technologies have for utilities and homeowners?
