With EHEIM thermocontrol+ e, we offer you the aquarium heater of the future. Intelligent and ingeniously designed.

The EHEIM Thermocontrol+ e 200 W is a “smart” adjustable aquarium heater. It provides precision control over water temperature via Wi-Fi, integrating into EHEIM’s Digital ecosystem (filters, lighting, etc.). Unlike fixed or preset models, it allows you to set your desired temperature, receive alerts, and synchronize with other equipment.

Key Features

• Adjustable temperature range: from 18 °C to 32 °C, giving flexibility for different species or seasonal variation.

• High precision: temperature control accuracy of about ± 0.5 °C.

• Notification system: If the aquarium temperature deviates more than ± 2 °C from the set point, the heater can send an email alert.

• Wi-Fi connectivity & control: you can monitor and change settings via smartphone, tablet, or PC/MAC. Synchronisation with other EHEIM.digital devices (e.g., EHEIM Professionel 5e filter, LEDcontrol+e lighting) is possible.

• Safety features:
    • Dry-run protection (Thermo Safety Control) prevents damage if the heater is not submerged sufficiently.
    • Fully waterproof (rated IPX8). For best Wi-Fi signal, the part with the red WiFi button should remain above the water line.

• Build & materials: Special laboratory glass covering that ensures a smooth finish, optimizes heat distribution, and avoids sharp hot surfaces that might harm aquatic life. High‐quality materials; made in Germany.

• Warranty: 3 years guarantee from the manufacturer.

Technical Specifications

• Power: 200 Watts at 50 Hz.

• Suitable aquarium size: approximately 300-400 litres.

• Height (length): about 386 mm.

• Diameter: approximately 32 mm.

• Cable length: approximately 170 cm (≈ 1.7 m).

• LED indicator lights: show heating status / whether heating is active.

• Controls: via WiFi, app/web interface; includes expert modes (for example using an external thermometer) and possible synchronisation with lighting or filter activity.

Advantages for using EHEIM thermocontrol+ e 200 W

• Flexibility in temperature setting makes it suitable for a wide variety of fish and aquatic organisms, including those with narrower tolerances or seasonal needs.

• Remote monitoring and alerting means you can be notified if something goes wrong (temperature drift, device failure, etc.).

• Integration with other “smart” aquarium components lets you automate behaviors (lowering temp at night, reducing power based on lighting, etc.).

• The safety features (dry-run, waterproofing) reduce risks of overheating or damage.

• Quality materials and robust construction aiming to reduce risk of breakage and increase lifespan.

Limitations

• The heater cannot cool; if ambient temperature gets too high, you’ll need external cooling (fans, chiller, etc.). The device only heats.

• WiFi performance can be impacted by immersion depth (especially the WiFi module/button) or barriers; for best signal, the top of the heater with the WiFi control part should be kept above water.

• Setup may require more effort (configuring WiFi, connecting with app/software, possibly synchronising other devices) than simpler heaters.

• Price is likely higher than non-smart heaters.

• If the ±2 °C deviation alert is critical (e.g. for very sensitive species), this is a helpful safety, but some users may want redundancy (multiple sensors or backup devices) just in case.
