The Eheim thermocontrol e is a top of the line, fully submersible aquarium heater designed for both freshwater and saltwater environments. The heater takes on the classic "hang in the water" design, but elevates its functionality with incredibly precise temperature adjustments between 20°C and 32°C, accurate within ± 0.5°C. The durable and impact-resistant heater has an output of 50 watts and is ideal for aquariums between 7 and 16 gallons in size. Includes dry-running protection to offer unmatched safety and control in the event of low water levels or other accidents.
This reliable heater has been constructed with a state-of-the-art glass jacket that increases the heating surface and acts as a heat shield, ensuring optimum heat emission and uniform distribution around the tank. Boasting the high quality construction standard of German engineering, the heater is ideal for both the experienced hobbyist and new fish keeper, with a 3 year manufacturer warranty for even greater ease of mind.
To the benefit of aquarists everywhere, this ultra modern electronic thermal device requires zero readjustment for accurate results and includes a convenient 5.5 foot long plug in cable, a double suction cup holder to securely place the heater anywhere in the tank and an easily visible control lamp that indicates red for "heating up" and green for "temperature reached".

This is a great, easy to use, quality aquarium heater.
I like it.
Great product, fast shipping, will be buying fish soon,.
It works very well. I was surprised how fast it worked on my new set up.
I have a review of the 150 Eheim. This one was bought as an emergency back up or quarantine tank heater, haven't had to use it yet but expect it will function just as well as the main tank heater.
With my son's first tank, the original heater struggled to reach the appropriate temperature. The Eheim doesn't struggle at all, despite being directly below the HVAC register in the room. The ease of controlling the temperature is fantastic.
