EHEIM thermocontrol 50 heater

With the EHEIM precision heater, your fish will enjoy the perfect temperature in any aquarium.

• Diameter Ø36 mm
• Height 243 mm
• Performance at 50 Hz 50 Watt
• Max. temperature 34°C
• Sea water Yes
• Min. temperature 18°C
• Freshwater Yes
• Packing dimensions (Width) 6.5 cm
• Packing dimensions (Height) 34.5 cm

Simple ideas often prove to be the most effective. Take for instance, the aquarium heater designed as a rod. This heating rod is easily suspended in the water to provide warmth. While the concept has remained unchanged for decades, significant advancements have been made over the years. Today, the EHEIM adjustable heater is a state-of-the-art electronic thermal device featuring cutting-edge technology. Its jacket, crafted from specialized laboratory glass, expands the heating surface, acts as a heat shield, and guarantees optimal and uniform heat distribution. No matter if you are heating a 20-liter or a 1000-liter aquarium, you have nine sizes available to choose from.

The EHEIM aquarium heater is a modern upgrade of the classic heating rod. The temperature can be set accurately between 18 and 34 °C and can be recalibrated if necessary (±2°). The precision in temperature control is ± 0.5 °C, and the heat remains stable. The heating function is signaled by an indicator light. This rod is fully watertight, can be entirely submerged, features an automatic dry run shut-off (Thermo Safety Control), and is compatible with both fresh and saltwater environments. One of the standout innovations is the glass jacket:

• It enhances the heating surface,
• Concentrates heat, ensuring optimal and even heat distribution, and
• Acts as a heat shield (safe to touch around your aquatic life).

The jacket is made from specialized laboratory glass, developed for research applications, ensuring it is free of pollutants that could leach into the water. It is resistant to chemical and biological agents, free from fissures and hairline cracks that could allow condensation to seep through. Even extreme temperature fluctuations that might occur during water changes will not damage this glass.
