Stiebel Eltron 206427 Mini-E™ 3-3 Thermostatic Electric Tankless Water Heater
3.0 kW • 277V • Commercial-Grade Precision for Point-of-Use Handwashing
The Stiebel Eltron Mini-E™ 3-3 (Part #206427) is a specialized 277V thermostatic tankless water heater engineered for commercial and institutional environments where voltage availability, temperature precision, and reliability are critical. Designed specifically for single handwashing sinks, this model combines advanced electronic temperature control with high-efficiency tankless operation, delivering consistent, code-compliant hot water performance in demanding applications.
Built for 277V Commercial Environments
Unlike standard residential models, the Mini-E™ 3-3 is designed to operate on 277V power, making it ideal for commercial buildings, schools, healthcare facilities, and industrial environments where 277V circuits are common.
With a 3.0 kW heating capacity at 277V, the unit delivers efficient temperature rise while maintaining lower amperage draw (approximately 11 amps), simplifying electrical integration in commercial systems.
Advanced Thermostatic Control Technology
The Mini-E™ 3-3 features electronic thermostatic temperature regulation, ensuring a stable outlet temperature even when inlet conditions or flow rates fluctuate. This level of control is essential for:
- Maintaining consistent handwashing temperatures
- Reducing scald risk
- Meeting code requirements for regulated environments
The unit is typically factory-set to ~100°F, with an adjustable range of approximately 86°F to 122°F, allowing precise customization based on application needs.
