EHEIM Jager Combined Heaters




With the EHEIM precision heater your fish receive exactly the right temperature – in any aquarium.

Obvious ideas often are the best ones. For example, the aquarium heater as a rod. The heating rod is simply hung in the water and heats it. It is true that the principle is still the same as decades ago. But a lot has changed in the meantime.

And today the EHEIM adjustable heater is an ultra-modern electronic thermal device with the best available technology. A jacket made from special laboratory glass increases the heating surface, serves as a heat shield and ensures optimum even heat emission. And no matter if you want to heat a 20 or a 1000 litre aquarium – you have 9 sizes to choose from.
