Water heater appliances and methods for operating same

摘要

Water heater appliances and methods for operating water heater appliances are provided. A water heater appliance includes a tank defining an interior volume, and a sealed system for heating water within the interior volume. The sealed system includes a compressor operable to compress refrigerant, and a first condenser downstream of and in fluid communication with the compressor. The first condenser is operable to heat water within the interior volume using energy from the refrigerant. The sealed system further includes a second condenser downstream of and in fluid communication with the first condenser. The second condenser is operable to heat water within the interior volume using energy from the refrigerant. The sealed system further includes an evaporator between and in fluid communication with the second condenser and the compressor.
