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.

The best
Style: 3.38 Fl Oz (Non SPF)
I’ve been using the La Roche-Posay Toleriane Double Repair Face Moisturizer for a few weeks now, and it’s honestly one of the best daily moisturizers I’ve tried—especially for sensitive skin. First thing I noticed is how lightweight it feels. It absorbs quickly and doesn’t leave that greasy or heavy film that a lot of “hydrating” lotions do. My skin feels instantly softer, but not suffocated. It layers really well under makeup too—no pilling or weird texture. What really stands out is how balanced my skin has been since using it. I tend to get dry patches but also occasional breakouts, and this somehow helps with both. It hydrates without clogging pores, and I’ve noticed less redness overall. The fact that it contains ceramides and niacinamide is a huge plus if you’re trying to repair your skin barrier. It’s also fragrance-free, which I personally look for because anything scented tends to irritate my skin. The only small downside is the price point compared to drugstore moisturizers, but honestly, a little goes a long way and the quality makes it worth it. Overall, I’d definitely recommend this if you have sensitive, combination, or dry skin and want something simple but effective. It’s become a staple in my routine.

Moisturizing & repairs skin barrier, but does pill.
Style: 3.38 Fl Oz (Non SPF)
Given myself a couple weeks of consistent use before giving a review. There are a lot of pros to this product which include: moisturizing and stays moisturized all day, made my PIE marks (post acne marks) fade a lot faster. Repairs my skin barrier, especially while using tretinoin nightly, not too thick but thick enough to keep my face hydrated. It does not have a smell. The cons are: slight burn for about 15 seconds but disappears, it pills if I apply too much. It does pill less if I pat it on my face versus rubbing; it does not pill when I apply liquid foundation. I just have to let it dry for 15-20 mins before applying makeup. I found the pros to overpower the cons and will continue to use this product.

Will buy again!
Style: 3.38 Fl Oz (Non SPF)
This is a very nice product. For the size it seems a bit expensive, but a little goes a long way and it may be a better value than I initially thought. My skin does look better, so it is doing it's job! I like the texture of it. It is fairly light, not oily, absorbs quickly into the skin, which I like. Highly recommend.

Lightweight bur actually hydrating
Style: 3.38 Fl Oz (Non SPF), Style: 3.38 Fl Oz (Non SPF)
I’ve tried so many moisturizers that either felt greasy, heavy, or just sat on top of my skin, but this La Roche-Posay moisturizer honestly surprised me. It’s super lightweight, absorbs quickly, and leaves my skin feeling soft and hydrated without feeling oily. My face feels smooth and refreshed after using it instead of sticky or coated. It layers really well and doesn’t make my skin feel overloaded. Definitely one of the best moisturizers I’ve used so far.
