3.5 kW • 240/208V • High-Efficiency Point-of-Use Handwashing Solution
For applications that demand higher performance, stronger temperature rise, and greater reliability, the Stiebel Eltron Mini™ 4-2 (Part #222039) delivers a professional-grade solution. Designed for single handwashing sinks, this 240/208V electric tankless water heater provides instant, consistent hot water with superior efficiency and performance compared to lower-voltage models.
Engineered for Maximum Point-of-Use Performance
The Mini™ 4-2 utilizes Stiebel Eltron’s advanced flow-activated heating technology, instantly heating water as it flows through the unit. This eliminates standby heat loss and ensures energy is used only when hot water is required, delivering both efficiency and responsiveness.
