Obvious ideas often are the best ones. For example, the aquarium heat-er 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 tech-nology. 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.

Completely submersible (watertight)

With automatic dry run shut-off (Thermo Safety Control)

A glass jacket increases the heating surface and ensures optimum even heat emission

Handy cable length ca. 170 cm

Including double suction cup holder

9 sizes for aquariums from 20 up to 1000 litres

Suitable for fresh and marine water

Precision, ease of use, quality and safety “Made in Germany”

The EHEIM aquarium heater is a further development of the legendary heating rod.

The temperature can be precisely set from 18 to 34 °C and if required recalibrated (±2°). The temperature control accuracy is ± 0,5 °C.

The heat is kept at a constant level. The heating function is indicated by a control lamp

The rod is absolutely watertight, can be fully submersed, has an automatic dry run shut-off (Thermo Safety Control) and is suitable for fresh and salt marine water.

One of the most important innovations is the glass jacket:

– It increases the heating surface,

– condenses the heat, ensures optimum even heat emission and

– forms a heat shield (touching it doesn’t harm the livestock).

The jacket is made from special laboratory glass, which was developed for research purposes. Therefore it is free from pollutants that could be released into the water. It is resistant to chemical and biological substances. It doesn’t have any fissures and hair cracks through which conden-sation could penetrate. And even extreme fluctuations of temperature that can occur during a water change do not harm this glass

With the EHEIM thermocontrol-e heating element your fish get the right temperature even more precisely – in every aquarium.

The obvious ideas are often the best. This also applies to the aquarium heating element. It is simply hung in the water and heats it up. The principle is the same as it was decades ago. But in the meantime the EHEIM controller heater has become an ultra-modern thermal device. The temperature can be set precisely and is measured even more precisely and kept more constant by the electronics. The coating 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 1200 litres aquarium – you can choose from 10 sizes.

Glass coating increases the heating surface and ensures optimum, even heat output

Convenient cable length approx. 170 cm

Including double suction holder

10 sizes for aquariums from 20 to 1200 litres

Suitable for fresh and marine water

Highest safety and reliability – 3 years warranty

Precision, comfort, quality and safety.

As you know, fish from tropical and subtropical waters need a certain constant water temperature. Before the engineer Eugen Jäger invented the aquarium heater decades ago, there was no really satisfactory solution to produce the appropriate water temperature. They dealt with complicated and sometimes curious methods. Some put the aquarium in the sun or by the heater or stove.

The EHEIM thermocontrol aquarium control heater is a further development of the legendary heating element and thermocontrol-e is the latest electronically controlled variant.

The temperature can be precisely adjusted from 20 to 32 °C. The control accuracy is ± 0.5 °C.

The heat is kept constant. A control lamp indicates the heating function.

The heater is absolutely waterproof, can be fully immersed, has a dry run protection (Thermo Safety Control) and is suitable for fresh and marine water. One of the most important innovations is the glass coating:

• It increases the heating surface,

• compresses the heat, ensures optimum, uniform heat output and

• forms a heat shield (the aquarium inhabitants do not mind touching it).

The coating is made of special laboratory glass. This was created for research purposes. It is therefore free of pollutants that could be released into the water. Chemical and biological substances do not attack it. There are no cracks and hairline cracks through which condensation water could pass. It is impact resistant. And even extreme temperature fluctuations, such as those that may occur during water changes, do not affect this glass.
