Expert Meeting: Exploring the Disconnect Between Rated and Field Performance of Water Heating Systems
September 28, 2012
Webinar
The primary objective of this expert meeting, hosted by the Building America ARBI team, was to better understand the issues related to field performance of residential water heaters and how site characteristics and user patterns and behaviors affect overall system performance. Understanding which types of water heaters experience the greatest performance degradation from lab to field, and what factors contribute to that degradation is essential in defining preferred applications for different water heater types.
