EHEIM Thermopreset Heater

guesswork out of temperature management by coming factory preset to 25°C, the optimal temperature for the vast majority of tropical freshwater and marine aquarium inhabitants. Simply plug it in and it maintains a constant, stable 25°C without the need for any manual adjustment or calibration, making it the ideal plug-and-play heating solution for beginner and experienced hobbyists alike. Precise electronic control guarantees exceptional temperature accuracy, while the highly efficient heating element ensures even heat distribution throughout the aquarium. The additional protective plastic casing provides enhanced mechanical stability and protection against accidental knocks during maintenance, and an LED indicator light clearly signals when the heating function is active. Built-in dry-running protection automatically prevents the heater from overheating if water levels drop during water changes, providing added peace of mind and long-term reliability. The slim and discreet design, with a diameter of just 2.8cm, ensures minimal visual impact within the aquarium and is suitable for both small nano tanks and larger setups. Backed by EHEIM's trusted German engineering and a 3-year warranty, the Thermopreset is a safe, simple, and dependable heating solution for freshwater and marine aquariums. EHEIM
