EHEIM thermocontrol 300, for aquariums from 600-1000L

With the EHEIM precision control heater your fish have the perfect temperature - in every aquarium.

The most obvious ideas are often the best. This also applies to the aquarium heater. It is simply placed in the water and heats it up. The principle is still the same as it was decades ago. But today the EHEIM control heater is a state-of-the-art thermal device. The temperature can be precisely set and maintained. A jacket made of special laboratory glass enlarges the heating surface, acts as a heat shield and ensures even heat distribution. And whether you want to heat a 20 or 1000 liter aquarium - you can choose from 9 sizes.
