Stiebel Eltron Mini-E 6-2 Thermostatic Tankless Water Heater 

Brand: Stiebel Eltron SKU: Mini-E 6-2 

Product Overview

The Stiebel Eltron Mini-E 6-2 point-of-use electric tankless water heater delivers an endless supply of warm water on demand for handwashing applications. Operating at an incredible 99% energy efficiency, this compact unit completely eliminates standby heat loss because it only heats water when you turn on the tap. Engineered in Germany, its microprocessor-controlled electronic thermostat guarantees a consistent, code-compliant outlet temperature even during water pressure fluctuations, making it an excellent fit for space-constrained residential and commercial layouts.

Unlike lower-output models in the series, the Mini-E 6-2 is uniquely designed with the capacity to supply warm water to either one or two handwashing sinks simultaneously in warm climates. Its ultra-compact footprint allows it to be installed easily right at the fixture, either left visible or neatly hidden away in cabinetry. Featuring advanced scale-resistant technology and an intelligent flow sensor, this dependable tankless water heater offers years of trouble-free operation without needing a pressure relief valve or a complex setup.

Key Features:

• Advanced Direct Coil Technology: Uses nichrome heating elements that silently vibrate on start-up, providing a self-cleaning action that provides superior limescale resistance and a long service life.
• Code-Compliant Thermostatic Control: Dynamically adjusts power output to maintain accurate, stable water temperatures, making it fully eligible for installations with strict temperature safety regulations.
• Multi-Sink Capability: Specially engineered with sufficient heating capacity to supply warm handwashing water to one or two sinks simultaneously.
• 99% Thermal Efficiency: Heats water instantaneously at the point of use with zero standby energy loss, maximizing your utility savings while conserving water resources.

Frequently Asked Questions:

• Q: Can the Mini-E 6-2 handle hard water?
• A: Yes. The unit features Stiebel Eltron’s Direct Coil heating system, which uses nichrome elements designed to silently vibrate upon every start-up. This self-cleaning action offers superior limescale resistance, making it an excellent choice for hard water areas.
• Q: Can I adjust the output water temperature?
• A: Yes. While the water heater is factory set to deliver a maximum handwashing temperature of 100°F, it can be field-adjusted by a qualified professional to any setting between 86°F and 122°F.
• Q: Does this water heater include a power cord or plug?
• A: No. The Mini-E 6-2 must be hardwired directly to a dedicated electrical circuit by a professional installer. It comes complete with an attached 2-foot wire pigtail harness for the connection.
