The Senville SENWH-HP50US is a 50 gallon heat pump water heater that draws heat from the surrounding air to heat water instead of relying on electric resistance alone. It earns a Uniform Energy Factor of 3.75 and a First Hour Rating of 69 gallons, so a household gets dependable hot water while spending noticeably less on electricity.
Backup 4500 W heating elements step in when demand outpaces the compressor, and the unit is ENERGY STAR certified, UL certified and AHRI listed. Senville backs it with a 7-year parts warranty and a 10-year compressor warranty.
