The company's SENSEI RX Series features Uniform Energy Factor (UEF) ratings up to 0.98, compared with ratings as low as 0.65 for many traditional tank-style water heaters. Higher UEF ratings indicate a greater percentage of the energy consumed is converted into useful hot water. Select SENSEI RX models also feature integrated recirculation pumps with Smart-Circ Intelligent Recirculation technology, which learns household hot water usage patterns and automatically circulates hot water before periods of demand.
