With the EHEIM JÄGER precision heater your fish receive exactly the right temperature – in any aquarium.

Obvious ideas often are the best ones. For example, the aquarium heater as a rod. The heating rod is simply hung in the water and heats it. It is true that the principle is still the same as decades ago. But a lot has changed in the meantime. And today the EHEIM adjustable heater is an ultra-modern electronic thermal device with the best available technology. A jacket made from special laboratory glass increases the heating surface, serves as a heat shield and ensures optimum even heat emission. And no matter if you want to heat a 20 or a 1000 litre aquarium – you have 7 sizes to choose from.

    Setting temperature

    • Turn the temperature selector ring to the desired temperature.
    • Monitor the aquarium water temperature using an accurate thermometer for at least 24 hours and make any necessary adjustments to compensate for calibration errors.
    • You should periodically monitor your aquarium water temperature with an accurate thermometer (Red light = heater in operation).

    Note: The temperature selector ring should only be used as a guide. Always use an accurate thermometer for water temperature measurement.

    Recalibration

    If, after a day or two in operation the setting scale does not correspond to the water temperature, refer to the following procedure to recalibrate the heater:

    • Switch off the heater and unplug it from the electrical outlet.
    • Measure the water temperature with an accurate thermometer.
    • Turn indicator arrow (red) point to the measured temperature.
    • Set the desired tank temperature with the temperature selector ring (blue).
