The Rheem ProTerra PROPH65-T2-RH375-30 is a 65-gallon hybrid electric water heater designed for high-efficiency hot water production in residential applications. Utilizing integrated heat pump technology and supplemental electric resistance elements, this unit achieves a Uniform Energy Factor (UEF) of 3.85—making it one of the most efficient models available for its capacity class.
This model is suitable for installations in conditioned or semi-conditioned environments such as basements, mechanical rooms, and utility closets where adequate air volume and temperature ranges (45°F–120°F) are available for heat pump operation. Factory-installed EcoNet™ connectivity allows remote system monitoring, diagnostics, and configuration via mobile interface or BMS integration.
