Webinar Description

Historically, there is considerable uncertainty about how well products newly introduced to the marketplace actually perform. That's why researchers at Silicon Valley Power partnered with Pacific Northwest National Laboratory to test a new water and space heating combination system that boasts the capability to decrease peak demand for customers, reduce climate impact, and increase energy efficiency. Join DEED on April 18 at 2:00 PM EDT to hear what the researchers experienced when putting the system, which uses a CO2 heat pump water heater that also serves as a space heater, into a controlled field demonstration and discuss how your utility might be able to encourage customers to use a similar system to reduce peak load demand and increase efficiency.
