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.

  • Simple and safe recalibration (±2 °C)
  • Temperature control accuracy ± 0,5 °C
  • Heat kept at a constant level
  • Heating function is indicated by a control lamp
  • 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

Vielen Dank für das Stellen einer Frage. Wir werden versuchen, diese schnellstmöglichst zu beantworten.
In meinem Aquarienheizer ist Feuchtigkeit. Ist dies gefährlich?“

In meinem Aquarienheizer ist Feuchtigkeit. Ist dies gefährlich?

In meinem Aquarienheizer ist Feuchtigkeit. Ist dies gefährlich?

Nein, jeder Aquarienheizer der unser Haus verlässt wird einer Dichtheitsprüfung unterzogen. Somit können wir gewährleisten, dass alle Aquarienheizer die unser Haus verlassen wasserdicht sind.

 

Wenn Sie jedoch am Glaskolben in ihrem Aquarienheizer einen Feuchtigkeitsbeschlag bemerken, dann hat sich vermutlich Schwitzwasser gebildet. Diese Schwitzwasserbildung kann folgenden Grund haben.

 

Wenn der Aquarienheizer das Aquarienwasser erwärmt, entstehen im Heizer selbst sehr hohe Temperaturen. Daher dehnt sich die Luft im Heizer aus. Damit der Heizer durch den jetzt entstehenden Überdruck nicht platzt, entweicht diese Luft über das Kabel.

 

Wenn der Heizer abschaltet, zieht sich die erkaltende Luft zusammen und es entsteht ein Unterdruck. Jetzt wird Luft über das Kabel in den Heizer hineingezogen. Da es sich je nach Wetterlage oder Jahreszeit um sehr feuchte Luft handeln kann, kondensiert diese feuchte Luft im Inneren des Heizers und schlägt sich an der Glasscheibe, als kältestem Teil des Heizers, nieder.

 

Da dieser Feuchtigkeitsbeschlag keine leitende Verbindung zum Aquarienwasser hat, ist der Betrieb völlig ungefährlich. Auch die Funktion des Aquarienheizers wird in keiner Weise beeinträchtigt.
