Stiebel Eltron 236136 Mini-E™ 3.5-1 Thermostatic Electric Tankless Water Heater
3.5 kW • 120V • Advanced Temperature-Controlled Point-of-Use Performance
The Stiebel Eltron Mini-E™ 3.5-1 (Part #236136) represents the highest-output thermostatic model in the Mini-E™ 120V lineup, engineered for single handwashing sinks that demand both precision temperature control and stronger performance. Combining electronic thermostatic regulation with self-modulating tankless technology, this unit delivers consistent, code-compliant hot water while maximizing efficiency.
Precision Thermostatic Control for Reliable Performance
Unlike standard point-of-use heaters that rely on flow restriction alone, the Mini-E™ 3.5-1 features advanced electronic temperature control that continuously monitors and adjusts output. This ensures a stable outlet temperature even with fluctuations in inlet water temperature or flow rate.
The unit is factory-set to approximately 100°F for ideal handwashing, with an adjustable range of 86°F to 122°F, allowing fine-tuning for specific applications and compliance requirements.
High Output for Demanding Conditions
With a 3.5 kW heating capacity at 120V, the Mini-E™ 3.5-1 delivers enhanced temperature rise and supports flow rates up to approximately 0.66 GPM with the supplied aerator, making it ideal for environments where lower-output units may fall short.
This makes it particularly effective in:
- Colder climates
- Higher-traffic handwashing stations
- Installations requiring consistent, comfortable water temperature
