With the adjustable precision heater EHEIM your fish enjoy the exact temperature in every aquarium. Obvious ideas are often the best. So it is with the aquarium heater. It simply hangs in the aquarium to heat it. The principle is the same as it was decades ago. But since then, the EHEIM adjustable heater has become a state-of-the-art appliance meeting the latest technical standards. The temperature is precisely regulated and remains constant. A special laboratory glass jacket increases the heating surface, acting as a heat shield and guaranteeing even heat emission.
