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, a first condenser downstream of and in fluid communication with the compressor, and a second condenser downstream of and in fluid communication with the compressor. The first and second condensers are each operable to heat water within the interior volume using energy from the refrigerant. The sealed system additionally includes a valve in fluid communication with the first and second condensers and configured to vary a ratio of refrigerant flow through the first and second condensers.
