Heat pump water heaters (HPWH) run on electricity and move heat from ambient air to water in a tank. Depending on ambient conditions, usage patterns, control modes and equipment specs, HPWH can reduce energy for water heating by roughly 50-75%. Split units (compressor separate from tank) and packed units (compressor combined with tank) are available.
