Sometimes, the simplest ideas are the best. Take the aquarium heater designed as a rod, for instance. This heating rod is simply suspended in the water to warm it up. While the concept has remained unchanged for decades, significant advancements have taken place over the years. Today, the EHEIM adjustable heater is a state-of-the-art electronic heating device, utilizing the latest technology. A jacket made from specialized laboratory glass enhances the heating surface, acts as a thermal shield, and ensures optimal heat distribution. Whether you need to heat a 20 or a 1000-liter aquarium, you have 9 sizes to choose from.

The EHEIM aquarium heater is an evolution of the classic heating rod.
The temperature can be accurately adjusted between 18 and 34 °C and can be recalibrated if necessary (±2°). The temperature control maintains an accuracy of ± 0.5 °C.
Heat is consistently maintained at the desired level, with the heating function indicated by a control light.
This rod is fully waterproof, can be completely submerged, features an automatic dry run shut-off (Thermo Safety Control), and is compatible with both freshwater and saltwater.
One of the key innovations is the glass jacket:
- It expands the heating surface,
- concentrates the heat, ensuring optimal and even heat distribution, and
- serves as a thermal shield (safe for your aquatic life).
The jacket is crafted from special laboratory glass designed for research applications. Thus, it is free of pollutants that could leach into the water. It is resistant to chemical and biological agents, devoid of fissures and hairline cracks that could allow condensation to enter. Even significant temperature variations that may occur during water changes will not affect this glass.
