For example, an aquarium heater as a stick. The heating rod is simply suspended in the water and heats it. It's true that the principle remains as it was decades ago. But much has changed in the meantime. Today, the adjustable EHEIM heater is a highly modern electronic thermal device with the best available technology. Its casing made of special laboratory glass increases the heating surface, acts as a thermal shield, and ensures perfectly even heat distribution. And regardless of whether you want to heat a 20-liter or 1000-liter aquarium - you have 9 sizes to choose from.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eBenefits of EHEIM Thermostatic Heaters\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003ePrecise temperature adjustment from 18 to 34 °C\u003c\/p\u003e\u003cp\u003eSimple and safe recalibration (±2 °C)\u003c\/p\u003e\u003cp\u003eTemperature control accuracy ±0.5 °C\u003c\/p\u003e\u003cp\u003eThe heat retains a constant level\u003c\/p\u003e\u003cp\u003eThe heating function is indicated by a control lamp\u003c\/p\u003e\u003cp\u003eCompletely waterproof (sealed)\u003c\/p\u003e\u003cp\u003eWith automatic shut-off when dry (thermal safety control)\u003c\/p\u003e\u003cp\u003eThe glass casing increases the heating surface and ensures ideal even heat distribution\u003c\/p\u003e\u003cp\u003eConvenient cable length approximately 170 cm\u003c\/p\u003e\u003cp\u003eIncludes double suction cup holder\u003c\/p\u003e\u003cp\u003e9 sizes for aquariums from 20 to 1000 liters\u003c\/p\u003e\u003cp\u003eSuitable for fresh and saltwater\u003c\/p\u003e\u003cp\u003ePrecision, ease of use, quality, and safety \"Made in Germany\"\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThe EHEIM aquarium heater is a further development of the legendary thermal rod.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThe temperature can be precisely adjusted from 18 to 34 °C and can be recalibrated if necessary (±2°).
