Stiebel Eltron 236009 Mini-E™ 4-2 Thermostatic Electric Tankless Water Heater
3.5 kW • 240/208V • Precision-Controlled High-Performance Point-of-Use Solution
The Stiebel Eltron Mini-E™ 4-2 (Part #236009) is a premium thermostatic tankless water heater engineered for single handwashing sinks in commercial and high-demand environments. Designed to operate on 240/208V power, this unit delivers enhanced temperature stability, stronger performance, and superior efficiency compared to standard 120V models—making it an ideal solution where consistency and reliability are critical.
Advanced Thermostatic Control for Consistent Temperature
At the core of the Mini-E™ 4-2 is electronic thermostatic temperature regulation, which continuously monitors and adjusts output to maintain a stable outlet temperature. Unlike non-thermostatic units that rely solely on flow restriction, this system ensures:
- Consistent water temperature regardless of flow variation
- Improved user safety with reduced scald risk
- Reliable performance in fluctuating inlet conditions
Factory-set to approximately 100°F, the unit offers an adjustable range of 86°F to 122°F, allowing precise customization for specific applications and compliance requirements.
Enhanced Performance with 240/208V Power
Operating at 3.5 kW on 240/208V, the Mini-E™ 4-2 delivers greater temperature rise and improved flow performance compared to lower-voltage models. With typical flow rates of approximately 0.50–0.66 GPM, it provides consistent and comfortable handwashing even in colder climates or higher-use environments.
This higher voltage configuration makes it particularly effective for:
- Commercial buildings
- Facilities with colder incoming water temperatures
- Applications requiring reliable, consistent hot water output
