Regular price $294.84
Shipping calculated at checkout.

✨Small & Reliable Water Heating for Handwashing

The Stiebel Eltron Mini™ tankless water heaters are designed for seamless installation right at the point-of-use. By heating water instantaneously as it flows through the unit, standby heat losses are completely eliminated.

The highly efficient heating elements are controlled by a simple, responsive flow switch. For added peace of mind, all Mini™ water heaters come equipped with a safety high-limit switch featuring a manual reset.

Included Features

📜 Code-Compliant Control: Thermostatic control ensures safety and compliance.

🌡️ Factory Set: Pre-configured at a comfortable 100°F (38°C).

🚰 Endless Hot Water: Provides an unlimited supply of hot water tailored for handwashing.

⚙️ Adjustable Output: Easily adjust the temperature output between 86–122°F (30–50°C) via a potentiometer located right under the cover.

🚀 Booster Applications: The Mini™ model accepts a maximum incoming water temperature of 122°F (50°C), making it perfect for booster setups.

🏆 Proven Reliability: Built to last with Stiebel Eltron's trusted engineering.

🔍 Ultra-Compact Design: Extremely compact footprint allowing it to be mounted easily in plain sight.

🔄 Flexible Installation: Can be mounted either above or below the fixture with fittings pointing up or down.

🔌 Ready to Wire: Includes a pre-wired pigtail for straightforward installation.

🛠️ Easy Installation: Simple and hassle-free to install, Mini™ water heaters offer maximum flexibility—they can be located either above or below the fixture with water connections pointing up or down. Best of all, no pressure relief valves, drains, or circulating pumps are required.


⚙️ Mini™6-2 Mechanical Models

💧 Straightforward Dependability: Relying on a reliable, classic mechanical flow switch mechanism for instantaneous heating.

🧊 Inlet Water Constraint: Mechanical units are strictly suitable for cold-water supply lines only and cannot accept pre-heated booster water.

📜 Code-Compliant Warm Water Output: An electronic control board pairs with an automatic flow rate control to maintain precise outlet temperatures despite water supply pressure fluctuations. Ideal for jurisdictions requiring strict code-enforced temperature limits.

⚙️ Adjustable Output: Factory set to deliver water at 100°F (38°C), but easily field-adjustable by the installer between 86–122°F (30–50°C) via an internal potentiometer.

🚀 Inlet Booster Capability: Accepts incoming pre-heated water up to 122°F (50°C). It acts as a perfect booster for isolated sinks located far from a main hot water source—delivering warm water instantly and shutting down automatically once hot water arrives from the primary heater.

🌡️ New Thermostatic Mini™-E Models

⚠️ Installation Safety Notes:

  • Connect only to an electrical circuit protected by a Class A Ground Fault Interrupter (GFCI).

  • Copper wiring must be used exclusively, sized properly to maintain a voltage drop under 3% under load.

  • Do not connect any Mini™ series unit to a salt-regenerated water softener or a saltwater supply system.

  • Nominal mains voltage is 110-120V and 220-240V.

  • Overcurrent protection sized at 100% of load. Tankless water heaters are considered a non-continuous load.

  • Each Mini & Mini-E model ships with appropriately sized aerator(s) that should be installed for optimal performance
    Mini™-E models are factory set for 100°F output.

  • Mechanical units suitable for supply with cold water only. Thermostatic units can accept inlet water of 122°F.

  • Mini™ 2-1 is internally restricted to 0.32 GPM / 1.2 l/min. Mini™-E 2-1 is internally restricted to 0.40 GPM / 1.5 l/min.
    Mini™ 2-1 & Mini™-E 2-1 ship with a 0.35 GPM pressure compensating flow-reducer/aerator that must be installed.

  • Mini™ 2.5-1, 3-1 & Mini™-E 2.5-1, 3-1, 3-3, 3.5-1, 4-2, 4-3 ship with a 0.5 GPM pressure compensating flow-reducer/aerator that must be installed.

  • Mini™ 3.5-1, 4-2 ship with a 0.66 GPM and a 0.5 GPM pressure compensating flow-reducer/aerator. One must be installed based on desired output temperature.

  • Mini™ 6-2 ships with a 1.0 GPM pressure compensating flow-reducer/aerator that must be installed.

  • Mini™-E 6-2, 6-3 ship with two 0.5 GPM pressure compensating flow-reducer/aerators that must be installed, plus an additional 1.0 GPM pressure compensating flow-reducer/aerator for use if plumbed to 1 sink.

  •  Nominal mains voltage is 110-120V and 220-240V.

  • Overcurrent protection sized at 100% of load. Tankless water heaters are considered a non-continuous load.

  • Caution: connect only to a circuit protected by a class A ground fault interrupter. 

  • Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load. 

  • Mechanical units suitable for supply with cold water only. Thermostatic units can accept inlet water of 122°F.

  • Do not connect to a salt-regenerated water softener or a water supply of salt water.
