Abstract
Modifications of the DOE test procedure for water heaters Uniform Test Method for Measuring the Energy Consumption of Water Heaters were made to include a dedicated water heating heat pump, system equipped with a 50 gallon electric water heater tank. Also presented are laboratory tests and results which provided the basis for the test methods used. Tests included determination of recovery efficiency, standby loss, and water heater jacket loss -- all under static or no-draw conditions -- and a synamic test in which water is withdrawn according to a 'typical-use' schedule. Energy requirements predicted by the proposed (static) procedure were in good agreement with measured energy consumption for the dynamic test in limited testing.
