The Eheim thermocontrol aquarium heater was formerly known as the Eheim Jäger aquarium heater. These are extremely efficient, ultra-modern electronic thermal devices for heating your aquarium. There are 9 heaters in the range, which come with many features, are suitable for aquariums from 20 to 1000 litres.

Eheim thermocontrol heaters are made with a laboratory quality glass jacket which had been created for research purposes. It is free of pollutants that could be released into the water and neither chemical nor biological substances attack it.

Energy Efficient!!!

This type of glass enlarges the heating surface, compresses the heat, ensures optimal, even heat emission. The heat disperses more easily, meaning that the element does not need to get as hot (forming a heat shield which the aquarium habitants do not mind touching). This uses less electricity, meaning that you do not need a heater as big as some other brands i.e. a 300w Eheim thermocontrol heater is suitable for aquariums from 600 to 1000 litres (most 300w heaters from other brands will only do 400!).

Features:

• The temperature can be precisely adjusted from 18 to 34°c.
• Can be recalibrated if required (± 2°c), to suit your aquarium.
