Interaction between Heat Pump Water Heaters and Heating System
Water heating represents approximately 18 percent of residential energy consumption annually. Heat pump water heaters (HPWHs) offer an efficient option for residential water heating, because they have the ability to reduce water heating energy consumption by up to 63 percent. To achieve such high efficiencies, HPWHs employ a refrigeration cycle to move heat from the…
