Stiebel Eltron 206429 Mini-E™ 6-3 Thermostatic Electric Tankless Water Heater
5.5 kW • 277V • Maximum Commercial Performance with Precision Temperature Control
The Stiebel Eltron Mini-E™ 6-3 (Part #206429) is a high-capacity, thermostatically controlled point-of-use tankless water heater engineered for commercial environments operating on 277V electrical systems. Designed for single handwashing sinks, this model delivers exceptional temperature stability, increased flow capability, and energy-efficient performance, making it one of the most powerful and precise solutions in the Mini-E™ lineup.
Designed for 277V Commercial Infrastructure
The Mini-E™ 6-3 is purpose-built for 277V applications, commonly found in office buildings, healthcare facilities, schools, and institutional settings. This voltage compatibility allows for efficient integration into commercial electrical systems while maintaining lower amperage draw relative to output.
With a 5.5 kW heating capacity, the unit delivers a substantial temperature rise and consistent output, ensuring dependable performance even in colder climates or high-demand environments.
Advanced Thermostatic Control Technology
At the core of the Mini-E™ 6-3 is electronic thermostatic temperature regulation, which continuously monitors and adjusts heating output to maintain a stable, precise outlet temperature.
Factory-set to approximately 100°F for optimal handwashing, the unit features an adjustable temperature range of 86°F to 122°F, allowing customization for safety, compliance, and user comfort.
This ensures:
- Consistent temperature regardless of flow variation
- Reduced risk of scalding
- Reliable compliance with handwashing standards in regulated environments
High Output for Demanding Applications
With 5.5 kW of heating power, the Mini-E™ 6-3 provides significantly greater performance than lower-wattage models. Supporting flow rates of up to approximately 1.0 GPM, it delivers strong, consistent hot water output suitable for higher-traffic applications.
This makes it ideal for:
- High-use commercial restrooms
- Facilities with colder incoming water temperatures
- Environments requiring consistent and reliable performance
