For example, an aquarium heater as a stick. Simply hang the heating rod in the water and it 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 modern electronic thermal device with the best available technology. Its special laboratory glass casing increases the heating area, acts as a thermal shield, and ensures ideal, even heat distribution. Whether you want to heat a 20 or 1000-liter aquarium - you have 9 sizes to choose from.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003ebenefits of EHEIM thermal heaters\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003ePrecise Edit of temperature from 18 to 34 °C\u003c\/p\u003e\u003cp\u003eEasy and safe recalibration (±2 °C)\u003c\/p\u003e\u003cp\u003eTemperature control accuracy ± 0.5 °C\u003c\/p\u003e\u003cp\u003eMaintaining heat at a constant level\u003c\/p\u003e\u003cp\u003eThe control lamp indicates the heating function\u003c\/p\u003e\u003cp\u003eFully compact (waterproof)\u003c\/p\u003e\u003cp\u003eWith automatic shut-off when dry (thermal safety control)\u003c\/p\u003e\u003cp\u003eThe glass cover increases the heating area and ensures ideal even heat distribution\u003c\/p\u003e\u003cp\u003eConvenient cable length of approximately 170 cm\u003c\/p\u003e\u003cp\u003eIncludes a double holder for the suction cup\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 heating rod.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThe temperature can be precisely adjusted from 18 to 34 °C and recalibrated if necessary (±2°).
