It’s like pulling energy savings out of thin air. The Hybrid Heat Pump water heater from American Standard Water Heaters features five operating modes, plus the i-Memory algorithm that ensures hot water when needed, and energy savings when it’s not. With up to 4.01 UEF, the Hybrid also features one powered and one magnesium anode rod. In addition to 50- and 80-gallon capacities, the Hybrid is now available in a 65-gallon capacity. All models come with a 10-year limited warranty for tank and parts.
