May 13 webinar looks at energy savings of heat pump water heaters

The findings from a study that examines the efficiency of heat pump water heaters (HPWHs) in cold climates will be presented on May 13 from 11 a.m. to noon by the Center for Energy and Environment (CEE). HPWHs have been increasingly popular in southern states, but 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, which was supported in part by a grant from the Minnesota Department of Commerce through its Conservation Applied Research and Development (CARD) Grant Program. A final report of the study is forthcoming in this newsletter. Schoenbauer will touch on how HPWHs affect homes from a whole house perspective. The presentation will 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.

The webinar is geared for utility program managers, home builders and contractors, residential architects, and mechanical equipment manufacturers. More information on the webinar, “Quantifying Energy Savings from Heat Pump Water Heaters in Cold Climate Homes,” is available.
