This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.When we think of hot water and water heating efficiency we often think of the big tank in our basements or garages, but that is only part of the story. Service hot water is a system consisting of not only a water heater, but piping, fixtures, and people too. In this session authors will discuss field and lab work that characterized hot water usage, distribution system effects and how these whole system approaches effect how we think about efficiency. Heat Pump Water Heaters (HPWHs) have been around for a long time. New product offerings indicate renewed interest in this technology. This session presents laboratory performance results from testing of the residential tank-integrated HPWHs available currently on the US market, and discusses climate-region-specific opportunities for energy savings in residential buildings. The HPWHs are evaluated with both standard and non-standard performance metrics, over a range of operating conditions and usage patterns.Parametric Laboratory Evaluation of Residential Heat Pump Water Heaters (CH-12-013)Paul Glanville, P.E., Associate Member, Douglas Kosar, Member, Daniel SuchorabskiThis product contains: Recorded Presentation Audio (mp3) Slides (pdf)Measured Residential Hot Water End Use (CH-12-014)Ben Schoenbauer, Associate Member, David Bohac, P.E., Member, Martha Hewett, MemberThis product contains: Recorded Presentation Audio (mp3) Slides (pdf)Water and Energy Wasted During Residential Shower Events: Findings from a Pilot Field Study of Hot Water Distribution Systems (CH-12-015)James Lutz, P.E.This product contains: Recorded Presentation Audio (mp3) Slides (pdf)Comparison of Heat Loss and Water Waste Characteristics of Bundled vs Single Pipe Hot Water Distribution Systems (CH-12-016)Carl Hiller, Ph.D., P.E.This product contains: Recorded Presentation Audio (mp3) Slides (pdf)
