About This Product

This tankless electric water heater provides hot water for the entire home in a compact, energy-efficient design. Built with advanced engineering, it delivers high operating efficiency and can help reduce water heating costs compared to a traditional electric tank unit. Its automatic flow control technology helps maintain your selected water temperature, even during periods of higher demand. Self-modulating performance continuously adjusts power use so only the needed electricity is used for heating. The compact design installs without venting, making it a practical option for homes where space savings matter. It can provide a steady hot water supply for up to 2 showers in warmer climates or about 1 to 1.5 showers in cooler climates, depending on conditions and sizing.
