A Couple of Final ThoughtsCommercial program customers range widely in business size and use of hot waterUnlike other categories of energy use, customer size and sophistication cannot predict water heating needs
Often, the smallest, most difficult customers to reach use the greatest amount of hot waterFood service and hospitalityThe complete CEE Program Summary is available at www.cee1.org Slide17
