Compare aquarium volume, heater length, adjustable or preset control, electronic or WLAN functions and the permitted installation position before choosing a model.
Choose an EHEIM aquarium heater by volume and control type
EHEIM and JÄGER aquarium heaters in this category provide different forms of temperature control for freshwater and marine aquariums. The range includes adjustable thermocontrol models, electronically controlled versions, the WLAN-enabled thermocontrol +e and thermopreset heaters with a fixed target temperature.
Choose the heater according to aquarium volume, room temperature, desired control type and installation conditions. An adjustable or networked heater offers different functions from a fixed-temperature model. Check the stated capacity range, overall length and permitted immersion or mounting position before ordering.
Position the heater where water circulates reliably and follow the minimum-water-level and safety instructions. Allow the appliance to acclimatise before switching it on or removing it from the water. Use an independent thermometer to verify the actual aquarium temperature.
