Eheim Ebo Jager Heater 25 Watt

The EHEIM Ebo Jager 25 W heater provides thermostatically controlled heat for a small aquarium. It uses an adjustable temperature scale rather than a single factory-set temperature, allowing the target to suit the animals being kept.

The thermocontrol design is suitable for both fresh and salt water, with a fully submersible glass body and a lamp that indicates active heating. Its thermostat has a recalibration adjustment, which is useful when checking the dial against an independent aquarium thermometer.

Choose the 25 W size after considering room temperature as well as water volume. Low wattage alone does not confirm that the heater will fit a shallow tank, so check its physical length and the required water level before installation. Maintain water circulation around the heater and follow the operating instructions during water changes.
