MIZUDO 11kW Tankless Electric Water Heater - 240V, 2.6 GPM, LED Display, ETL Certified

Meet the MIZUDO 11kW Tankless Electric Water Heater, a compact 240V unit designed to deliver hot water on demand without the bulk of a traditional tank. Its slim footprint (14.2" H x 9.5" L x 2.8" W) makes it a practical fit for tight spaces, closets, or utility nooks, while still powering 1–2 fixtures at once. This is water heating that adapts to your home without dominating your space.

Efficient, on‑demand hot water

Engineered for high efficiency, this model reaches up to 98% energy efficiency and heats water in about 3 seconds. With a maximum flow of 2.6 GPM, it can supply hot water to 1–2 points of use in parallel, minimizing wait times and helping you manage energy use more effectively. Compared with traditional tank heaters, it can contribute to lower electricity costs and a smaller monthly footprint, especially in smaller homes or apartments.

• 98% energy efficiency for on-demand hot water
• Up to 2.6 GPM flow for 1–2 fixtures simultaneously
• Potential electricity cost reductions versus tank-style systems

Smart temperature control and reliable performance

Temperature is effortless to manage with the LED touch display, allowing a precise range from 86°F to 140°F. A sophisticated control system adjusts heating power up to 20,000 times per second, helping maintain a steady output with a narrow tolerance (±1°F). The result is a comfortable, consistent shower or sink experience without abrupt temperature swings.

• LED touch display for quick temperature set-up
• Accurate 86–140°F range with ±1°F stability
• Real-time adjustment to water flow for steady temperature

Safety, certification, and peace of mind

Built with safety as a priority, the unit is ETL certified and includes leakage protection, over‑temperature protection, and dry‑heating protection. Each unit undergoes thorough factory testing to ensure safe, reliable operation from first use.

• ETL certification for safety and reliability
• Leakage protection and over‑temperature safeguards
• Dry‑heating protection and rigorous factory testing

Easy installation and practical uses
