Sometimes the simplest ideas are the most effective. Take the aquarium heater that functions as a rod, for instance. This heating rod is effortlessly suspended in the water and warms it up. While the concept remains unchanged from decades past, significant advancements have been made. Today, the EHEIM adjustable heater stands as a state-of-the-art electronic heating device, utilizing the latest technology. Its jacket made from specialized laboratory glass enhances the heating surface, acts as a thermal shield, and guarantees even heat distribution. Whether you need to heat a 20 or a 1000-liter aquarium, you have nine sizes to select from.

The EHEIM aquarium heater is an upgraded version of the iconic heating rod.
You can accurately adjust the temperature from 18 to 34 °C and recalibrate it if necessary (±2°). The precision of temperature control is ± 0.5 °C.
Heat levels are maintained consistently, with a control lamp indicating when heating is active.
The rod is entirely waterproof, can be fully submerged, features an automatic dry run shut-off (Thermo Safety Control), and is suitable for both fresh and saltwater.
One of the key innovations is the glass jacket:
- It expands the heating surface,
- concentrates the heat, ensuring optimal even distribution and
- provides a thermal shield (safe for your aquatic life).
This jacket is crafted from specialized laboratory glass, designed for research applications. Thus, it is free of pollutants that could leach into the water. It is resistant to both chemical and biological agents and is devoid of fissures or hairline cracks that could allow condensation to seep in. Even extreme temperature variations that may occur during water changes will not damage this glass.
