Clear ideas are often the best. For example, a 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 very modern electronic heating device with the best available technology. The casing made of special laboratory glass increases the heating surface, acts as a thermal shield, and ensures perfect and balanced heat distribution. 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 recalibrated if necessary (±2°). The temperature control accuracy is ±0.5 °C.

Heat is maintained at a constant level. The heating function is indicated by a control lamp.

The rod is completely waterproof, can be fully submerged, and features automatic shut-off when dry (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 optimal and balanced heat distribution and

- Forms a thermal shield (touching it does not harm marine life).

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. It is resistant to chemical and biological substances. It does not contain cracks or small fractures that might allow condensation to leak. Even extreme temperature fluctuations that can occur during water changes do not harm this glass.
