The EHEIM Jäger Aquarium adjustable Heater is an ultra-modern unit for the automatically heating of fresh and sea water aquaria. This heater is the first choice by aquarium people all over the world. Quality and security are a class of its own.
The EHEIM Jäger Aquarium Heater has a temperature adjustment scale ranging from 18°C to 34°C. The thermostat is designed to permit external resetting of the temperature. A control light shows whether the unit is warming up under thermostatic control or has been turned off by it. The EHEIM Jäger Aquarium Adjustable Heater is made of tough special glass (SCHOTT Duran laboratory glass) and suitable for both fresh and sea water. Therefore, it is free from pollutants, which could seep into the water. It is resistant to chemical and biological substances. It does not have any fissures and hair cracks, which condensation water can penetrate. And it is shatter-proof i.e. resistant to cold water shock, which can occur during maintenance or sudden water level changes. The heater can be fully immersed. The power supply cable with Europlug is 170 cm long. An inbuilt safety device prevents the unit being damaged by running dry as well as preventing the glass tube bursting. A dual-suction-pad holder for securing the unit to the glass tank wall is included. New model !

Can't calibrate the heater..it is always ON,it's always on, I don't trust it,if I turn the temperature to 18 or 30, it is on constantly.1st time I bought and the last.Jo F. at 01.11.2023:
Themperatureinstellung etwas fummelig, ansonsten tut es was es soll.Martin S. at 08.05.2023:
Bedienung und Ablesbarkeit etwas umständlicher als bei anderen geregelten Heizern (zB. Sera/Tetra/Visitherm). Qualität des Materials ist aber gut + Preis/Leistung ok. Der Heizer kann genauso nach einem Jahr ausfallen oder überheizen wie jede andere Marke auch (gerade wieder einen entsorgt). 25 W auf 25 L ist zu viel - überheizt er mit 25W/25L kommt ihr bei 40° C raus = sind die Fische hin.Uta V. at 27.01.2023:
Heizstab läuft bei mir seit über 7 Jahren im Aquarium völlig problemlos und zuverlässig. Klare Empfehlung!Eileen B. at 31.12.2020:
Die Heizung funktioniert super. Es gibt keinerlei Beanstandungen. Die Temperatur lässt sich von 18 bis 30 grad einstellenGonçalo R. at 11.04.2020:
The best thermo heater of all.
ItÂ’s surely gonna do the expected job.Arthur S. at 25.03.2020:
And I have been using such heaters for more than 10 years. Very high-quality thermostat at a good price!Alexey G. at 16.03.2020:
Сlean design. Can not be sterilized with boiling water really. The thermostat fails.Chen Z. at 29.12.2019:
One of the best heaters on the market.Volker H. at 18.12.2018:
Leider musste ich sehr schlechte Erfahrungen machen. Der Bimetallkontakt hat
nicht abgeschaltet. Mein Diskusbecken erreichte 40° C. Kein Fisch hat überlebt.Jarkko J. at 10.12.2018:
Would have expected better from Eheim, temperature adjustment is poor.Jurijs B. at 05.07.2018:Maxim B. at 20.09.2017:
Не работает датчик термоконтроля, греет без остановки, чуть не сварил всю рыбу.Erwin K. at 26.06.2017:
Sehr gute und zuverlässige Aquarium Heizung.Bjorn B. at 08.05.2017:
The best heater i have ever owned, i have 4 and all works perfect out of the box ;)Nikola K. at 10.03.2017:
Impossible to adjust at desired teperature. Red has only four clicks on the left and four clicks on the right side. I measure the temperature of my aquarium, I put the red ring at measured temperature of the water and then the blue ring I set on the desired temperature. Lamp is lit and the heating goes endlesly. I try to calibrate again, i find it is impossible becouse the red ring have only four clicks at a side. That means I have to adjust the blue ring on 22 celsius degrees to get 26 celsius in the water. Very annoying. This heater realy sucks. I can't understand why you have an option to calibrate when you can't calibrate it at desired temperature at all?Thomas K. at 24.10.2016:
Alles in allem ein gutes Gerät! Eheim Jäger halt. Was mich persönlich etwas nervt: die fein Einstellung ist manchmal nicht präzise genug. Wenn man Pech hat, verstellt sich das Thermostat, da es analog mechanisch Bimetall und nicht elektronisch ist. Für den Preis und dazu in Deutschland hergestellt jedoch in Ordnung.Oscar C. at 25.07.2016:
tengo uno de estos en cada uno de mis 4 acuarios y estoy muy satisfecho con su rendimientoGraham W. at 25.04.2016:
I have two 100w and one 300w running in different tanks. The 300w broke recently however when doing a water change and wasn't fully submerged. These are excellent heaters,however,I recommend the JBL heaters also as they have a run dry protection and also have plastic covering over the heater to prevent damage or burning fish.Guven K. at 21.03.2016:
Ich habe mir den 100 Watt Aquarium Heizstab gekauft. Läuft immer problemlos. Den Preis für den Heizer finde ich mal akzeptabel.Doron H. at 30.10.2015:
The best heater available in the market...1 x 300W Eheim heater is working on my 750L marine without any issues.
Saves money + saves electricity + long lasting.
