Often, the simplest ideas are the best. For example, a stick aquarium heater. The heating stick is simply suspended in the water and heats it. It's true that the principle remains the same as it has been for decades. However, much has changed in the meantime. Today, the adjustable EHEIM heater is a highly modern electronic thermal device with the best available technology. The special laboratory glass casing increases the heating surface, acts as a thermal shield, and ensures perfectly even heat emission. Whether you want to heat an aquarium with a capacity of 20 liters or 1000 liters - you have 9 sizes to choose from.

Precision, ease of use, quality, and safety "Made in Germany"

The EHEIM aquarium heater is a further development of the legendary heating rod.

The temperature can be precisely adjusted from 18 to 34 °C and recalibrated if necessary (±2°). The temperature control accuracy is ± 0.5 °C.

The heat maintains a constant level. The control bulb indicates the heating function.

The rod is completely sealed, can be fully submerged, and has an automatic shut-off in dry operation (thermal safety control) and is suitable for both fresh and saltwater.

One of the most important innovations is the glass casing:

- Increases the heating surface,

- Focuses heat, ensures ideal uniform heat emission and

- Forms a thermal shield (touching it does not harm living organisms).

The casing is made of special laboratory glass, developed for research purposes. Therefore, it is free from contaminants that may be released into the water. Resistant to chemical and biological substances. It does not contain cracks or hairline fractures through which condensation can seep. Even extreme temperature fluctuations that can occur during water changes do not harm this glass.
