EHEIM thermocontrol 25 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 25 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 Packing dimensions (Depth) 5 cm For aquariums up to approx. 25 Liter For aquariums of about 20 Liters Sometimes the simplest ideas are the most effective. Take the aquarium heater, for instance, which functions as a rod. This heating rod is simply submerged in the water to warm it. While the basic principle has remained unchanged for decades, significant advancements have been made since then. Today, the EHEIM adjustable heater is a state-of-the-art electronic heating device utilizing the latest technology. A jacket crafted from specialized laboratory glass enhances the heating surface, acts as a heat shield, and guarantees optimal heat distribution. Whether you need to heat a 20 or a 1000-liter aquarium, there are 9 sizes available to accommodate your needs. **Advantages of the EHEIM thermostatic heaters** - Accurate temperature adjustment from 18 to 34 °C - Easy and secure recalibration (±2 °C) - Temperature control precision of ± 0.5 °C - Maintains a consistent temperature - Heating function is signaled by a control light - Fully submersible (watertight) - Equipped with automatic dry run shut-off (Thermo Safety Control) - A glass jacket expands the heating surface and ensures effective, even heat distribution - Convenient cable length of approximately 170 cm - Comes with a double suction cup holder - Available in 9 sizes suitable for aquariums ranging from 20 to 1000 liters - Ideal for both freshwater and marine environments - Precision, user-friendliness, quality, and safety “Made in Germany” The EHEIM aquarium heater represents an evolution of the iconic heating rod. You can precisely set the temperature from 18 to 34 °C and recalibrate it as needed (±2°). The accuracy of temperature control is ± 0.5 °C, ensuring that the heat remains stable. The control lamp indicates when the heating function is active. This rod is completely watertight, can be entirely submerged, features an automatic dry run shut-off (Thermo Safety Control), and is compatible with both freshwater and saltwater. A key innovation is the glass jacket, which: - Expands the heating surface, - Concentrates the heat for optimal even heat distribution, and - Serves as a heat shield (safe to touch without harming your aquatic life). The jacket is made from specialized laboratory glass developed for research purposes, ensuring it is free from harmful pollutants that could leach into the water. It is resistant to chemical and biological substances and does not have any fissures or micro-cracks that could allow condensation to penetrate. Even extreme temperature fluctuations that may occur during water changes will not damage this durable glass.
