RESIDENTIAL WATER HEATER MEASURES<br />
The measures for this program are single technologies and not a water heating system that<br />
includes water heaters as well as components of a hot water distribution system such as<br />
pipe insulation and shower heads. There are five individual water heater measures to be<br />
analyzed and tested with customers. These are summarized in Table 7, which shows<br />
qualifying criteria and channel options.<br />
The five measures are grouped into two categories – Test Measures and Legacy Measures.<br />
Test Measures represent the newest, highest efficiency water heating technologies. A<br />
qualifying criterion for these measures is ENERGY STAR certification. They currently have<br />
high costs, limited availability, and low market penetration. These measures will be the<br />
subject of tests of new marketing approaches to uncover ways to lower barriers to market<br />
acceptance. Two work papers have been prepared to establish baselines for natural gas and<br />
electric water heater measures:<br />
