With the EHEIM thermocontrol heating element, your fish get exactly the right temperature in every aquarium.

The heating element is simply hung in the water and heats it up. The principle is still the same as it was decades ago. But in the meantime, the EHEIM controller heater has become a state-of-the-art thermo device. The temperature can be set precisely and is kept constant. The jacket made of special laboratory glass increases the heating surface, serves as a heat shield and ensures even heat emission. And whether you want to heat a 20 or 1000 litre aquarium - you can choose from 9 sizes.
