Sometimes the simplest ideas are the most effective. Take the aquarium heater designed as a rod, for instance. This heating rod is easily suspended in the water and efficiently warms it up. While the basic principle remains unchanged from decades ago, significant advancements have been made since then. The EHEIM adjustable heater is now a state-of-the-art electronic heating device featuring the latest technology. Its jacket, crafted from specialized laboratory glass, enhances the heating surface, acts as a heat shield, and guarantees uniform heat distribution. Whether you need to heat a 20 or a 1000-liter aquarium, there are 9 sizes available to suit your needs.

The EHEIM aquarium heater is an evolution of the classic heating rod.
The temperature can be accurately adjusted from 18 to 34 °C and can be recalibrated if necessary (±2°). The temperature control precision is ± 0.5 °C.
Heat is maintained at a stable level, and the heating function is shown by a control lamp.
This rod is entirely waterproof, suitable for full submersion, includes an automatic dry run shut-off (Thermo Safety Control), and is appropriate for both fresh and saltwater aquariums.
Among the key innovations is the glass jacket:
- It increases the heating surface,
- concentrates the heat, ensures optimal even heat distribution, and
- acts as a heat shield (safe to touch without harming aquatic life).
The jacket is constructed from specialized laboratory glass, designed for research applications. This means it is free from harmful substances that could leach into the water. It withstands chemical and biological agents, has no cracks or fissures that could allow condensation to enter, and can endure extreme temperature changes that may occur during water changes without issue.
