Stiebel Eltron 232099 Mini™ 3.5-1 Electric Tankless Water Heater
3.5 kW • 120V • Maximum Performance for Single Handwashing Sink Applications
When higher temperature rise and performance are critical at the point of use, the Stiebel Eltron Mini™ 3.5-1 (Part #232099) stands as one of the most powerful 120V tankless solutions available for single-sink applications. Designed with precision German engineering, this unit delivers reliable, on-demand hot water with enhanced output capacity, making it ideal for demanding environments and colder water conditions.
Engineered for High-Demand Point-of-Use Applications
The Mini™ 3.5-1 utilizes a flow-activated heating system that instantly heats water as it passes through the unit. This eliminates standby heat loss associated with tank systems and ensures maximum efficiency and immediate hot water delivery.
With its 3.5 kW heating capacity, this model provides one of the highest temperature rises in the Mini™ series on a 120V platform. It is specifically engineered for situations where lower-wattage units may struggle—such as colder climates, higher flow expectations, or critical handwashing environments.
