Sometimes the simplest ideas are the most effective. Take the aquarium heater, for example, designed in the form of a rod. This heating rod is simply suspended in the water to warm it up. While the concept has remained unchanged over the decades, significant advancements have been made. Today, the EHEIM adjustable heater stands as a cutting-edge electronic heating device featuring state-of-the-art technology. A protective jacket made from special laboratory glass enhances the heating surface, acts as a heat shield, and guarantees uniform heat distribution. Whether you're heating a 20 or a 1000 litre aquarium, you can select from 9 different sizes.

The EHEIM aquarium heater represents an evolution of the classic heating rod.
It allows for precise temperature settings between 18 and 34 °C, and can be recalibrated if necessary (±2°). The accuracy of temperature control is ± 0.5 °C.
It maintains a stable heat level, with a control lamp indicating when heating is in operation.
This rod is completely waterproof, fully submersible, features an automatic dry run shut-off (Thermo Safety Control), and is suitable for both freshwater and marine environments.
One of the key innovations is the glass jacket:
- It expands the heating surface,
- concentrates the heat, ensuring optimal and even heat distribution, and
- acts as a heat shield (touching it is safe for your aquatic life).
The jacket is crafted from specialized laboratory glass designed for research applications. It is free from harmful substances that could leach into the water and is resistant to chemical and biological agents. It features no cracks or fissures that could allow condensation to seep in. Even drastic temperature changes that might occur during water changes will not damage this glass.
