Level 3 content for introduction to Heat Pump Water Heaters (HPWH). This lecture focuses on performing calculations to determine a units yearly operational cost. These costs are compared between Oil/Gas, Electrica, and HP water heaters.
Problem Set 3.1 Calculate the estimated annual operational cost of a HPWH with a Uniform Energy Factor of 4.5. Assume a daily power usage of 13 kWh/day and an average electricity cost of $0.2/kWh.
Problem Set 1.1 What are some characteristics that can vary between water heaters? What is the difference between a conventional water heater and a heat pump water heater? Problem Set 1.2 What mode is the most efficient for the production of hot water? If planning to be away from the residence for...
Problem Set 2.1 What is the source of heat used by the HPWH to heat up the water inside the insulated tank? What substance goes from liquid to gas, and back to liquid in order to transfer heat to the water in the storage tank? Problem Set 2.2 What characteristics of a households affect the amount of...
