Clear ideas are often the best. For example, the rod-shaped aquarium heater. The heating rod is simply suspended in the water and heats it. It is true that the principle remains as it was decades ago. But much has changed since then. Today, the adjustable EHEIM heater is a highly modern electronic heating device with the best available technology. A casing made of special laboratory glass increases the heating surface, acts as a thermal shield, and ensures perfectly even heat emission. Whether you want to heat a 20-liter or 1000-liter aquarium - you have 9 sizes to choose from.

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 can be recalibrated if necessary (±2°). The temperature control accuracy is ± 0.5 °C.

The heat maintains a constant level. The heating function is indicated by the control lamp.

The rod is completely sealed against water, can be fully submerged, and features automatic shut-off when dry (thermal safety control) and is suitable for both freshwater and saltwater.

One of the most important innovations is the glass cover:

- Increases the heating surface,

- Focuses heat, ensuring ideal even heat emission and

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

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