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.

Nutrient-Packed Spirulina Powerhouse!
I've been taking the Micro Ingredients Organic Spirulina Supplement, and it has exceeded my expectations in every way. This organic spirulina supplement is a true powerhouse of nutrients, and it has become an essential part of my daily routine. One of the standout features of this supplement is its potency. With 3000MG per serving and 720 tablets in a single bottle, it offers exceptional value and a 4-month supply. That means I get all the benefits of spirulina without the need for frequent reordering. I appreciate that these tablets are free from fillers and are Non-GMO. It's reassuring to know that I'm consuming a pure and clean source of spirulina. The nutritional benefits are remarkable. Spirulina is rich in vegan protein, vitamins, and prebiotics, making it a fantastic addition to my diet. I've noticed an increase in energy and overall well-being since incorporating it into my daily regimen. The convenience of tablets makes it easy to incorporate into my busy schedule. There's no need for mixing or blending, which is a time-saver. In conclusion, the Micro Ingredients Organic Spirulina Supplement is a game-changer in the world of dietary supplements. It offers a premium source of organic spirulina, packed with essential nutrients and free from fillers. I highly recommend this supplement to anyone looking to boost their overall health and well-being. It's been a valuable addition to my daily routine, and I couldn't be happier with the results!
