Definitions:
Standby Heat Loss. Measure of how well the tank is insulated. Use a Kilowatt Hour meter and measure power consumed in a 24 hour period for a full tank at normal operating temperature and no water being added.
First Hour Rating. Measure how much hot water can be delivered over a one hour period, with a 140˚F tank water temperature and 60˚F incoming water temperature.
Usable Hot Water. Measure of how cold incoming water mixes with the stored hot water. Start with hot tank. Draw water at 1/2 GPM until water temperature drops 25%. Measure amout of water drawn. Repeat for
1 GPM and 2 GPM.
