With the EHEIM thermocontrol-e heating element, your fish will enjoy the ideal temperature with even greater precision in every aquarium. Often, the simplest ideas are the most effective, and this holds true for the aquarium heating element. It is designed to be easily submerged in the water, providing efficient heating just as it has for many years. However, the EHEIM controller heater has evolved into a highly advanced thermal device. The temperature can be accurately set and is measured with enhanced precision, maintained consistently thanks to advanced electronics. The special laboratory glass coating not only increases the heating surface but also serves as a heat shield, ensuring an even distribution of warmth. Whether you need to heat a 20-liter or a 1200-liter aquarium, there are 10 different sizes available.

Advantages of the EHEIM control heater thermocontrol-e

  • Accurate temperature adjustment from 20 to 32 °C
  • No need for readjustment
  • Control accuracy of ± 0.5 °C
  • Stable temperature maintenance
  • Control lamp indicates heating status (red: heating; green: temperature achieved)
  • Fully submersible and waterproof
  • Equipped with dry-running protection (Thermo Safety Control)
  • The glass coating enhances the heating surface and ensures optimal, uniform heat distribution
  • Convenient cable length of approximately 170 cm
  • Includes double suction holder
  • Available in 10 sizes for aquariums ranging from 20 to 1200 liters
  • Compatible with both fresh and saltwater
  • Exceptional safety and reliability - 3 years warranty

Combining precision, comfort, quality, and safety, the EHEIM thermocontrol aquarium control heater is a significant advancement over the original heater designed by engineer Eugen Jäger decades ago. Before its invention, maintaining an appropriate water temperature was a challenge, often employing complicated or unconventional methods, such as placing the aquarium in sunlight or near a heater or stove.

The thermocontrol-e represents the latest electronically controlled version of this legendary heating element. You can finely adjust the temperature between 20 and 32 °C with a control accuracy of ± 0.5 °C, ensuring a steady temperature. A control lamp will indicate whether the heater is active. This heater is completely waterproof, can be fully immersed, and features dry-run protection (Thermo Safety Control), making it suitable for both fresh and marine water.

One of the notable innovations is the glass coating, which:

  • Increases the heating surface,
  • Consolidates the heat, ensuring optimal and even heat output, and
  • Acts as a heat shield (safe for aquarium inhabitants to touch).

This coating is crafted from special laboratory glass designed for research purposes, ensuring it is free from pollutants that could leach into the water. It is resistant to chemical and biological substances, is crack-proof, and can withstand extreme temperature fluctuations, such as those that may arise during water changes.

Very spacious and beautiful
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.

This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.
