Simple ideas are often the most effective. Take the aquarium heater, for instance, designed as a rod. This heating rod is easily suspended in the water to provide warmth. While the concept has remained consistent for decades, significant advancements have been made. Today, the EHEIM adjustable heater represents a state-of-the-art electronic thermal device featuring the latest technologies. Its casing, crafted from specialized laboratory glass, not only enhances the heating surface but also acts as a heat shield, ensuring uniform heat distribution. Whether you're heating a 20 or a 1000-liter aquarium, you can choose from 9 different sizes.

The EHEIM aquarium heater is an enhancement of the renowned heating rod. The temperature can be accurately set between 18 and 34 °C and recalibrated if necessary (±2°). Its temperature control accuracy is ± 0,5 °C, ensuring consistent heat retention. The heating functionality is easily identifiable via a control lamp. The rod is completely waterproof, fully submersible, features an automatic dry run shut-off (Thermo Safety Control), and is compatible with both freshwater and saltwater aquariums. A key innovation is the glass jacket:

• It expands the heating surface,
• Concentrates heat for optimal even heat emission, and
• Acts as a heat shield (safe to touch for aquatic life).

The jacket is crafted from specialized laboratory glass, developed for research applications. This means it is free from contaminants that might leach into the water. It is also resistant to both chemical and biological agents, ensuring no cracks or fissures through which condensation could enter. Even extreme temperature variations that may occur during water changes will not affect this durable glass.
