Stiebel Eltron 236135 Mini-E™ 2.5-1 Thermostatic Electric Tankless Water Heater
2.4 kW • 120V • Precision-Controlled Point-of-Use Handwashing Solution
The Stiebel Eltron Mini-E™ 2.5-1 (Part #236135) is a premium thermostatically controlled tankless water heater engineered for applications where temperature precision, efficiency, and reliability are critical. Designed specifically for single handwashing sinks, this advanced unit combines on-demand heating with electronic temperature control, delivering consistent hot water performance that standard tankless models cannot match.
Advanced Thermostatic Control for Consistent Performance
Unlike basic point-of-use heaters, the Mini-E™ 2.5-1 features integrated electronic thermostatic control, maintaining a stable outlet temperature regardless of minor fluctuations in flow or inlet water temperature. This ensures consistent handwashing conditions, improved safety, and enhanced user comfort.
Factory-set to approximately 100°F, the unit offers an adjustable temperature range (typically 86°F to 122°F), allowing precise tuning for specific applications. This level of control is especially valuable in environments where temperature consistency and compliance standards are required.
Optimized Tankless Efficiency with Enhanced Output
With a 2.4 kW heating capacity, the Mini-E™ 2.5-1 provides increased performance compared to lower-wattage models, delivering a typical flow rate of approximately 0.40–0.50 GPM. This makes it ideal for installations where slightly higher demand or colder incoming water temperatures require additional heating power.
The system’s self-modulating technology continuously adjusts energy use based on demand, ensuring optimal efficiency without sacrificing performance.
