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.

Love all the Barkbox toys
Color: Christmas Consuela, Size: Large Dog
This is our third "Consuela"! Our dogs LOVE these toys, and they are the most durable we can find for our heavy chewers. They really like the ball inside as well. Highly, highly recommend these toys. I won't be buying other toys anymore, just barkbox.

My dog is a toy destroyer
Color: Consuela the Cactus - Large, Size: Large Dog, Color: Consuela the Cactus - Large, Size: Large Dog
I’ve had a hard time trying to find toys that my dog, Zara loves because she’s actually very picky. Ive gotten plenty of Kong toys that are well known to be indestructible but she wants nothing to do with them. Then I got her ropes and that seemed to be good for a while until she was getting sick in the middle of the night from eating all of the string. Stuffed toys aren’t good because she’ll rip them within seconds and eat all of the stuffing. I felt like I’ll never score the perfect toy for her. I found the three layered cactus toy and decided to give it a go. It’s clearly designed to be ripped and destroyed to get the ball in the middle which is actually really cute and fun to see all of the layers. The cactus arms have stuffing and of course that’s the first thing she went for and ate. I had to watch her and make sure I took the stuffing away before she ate it. And before I knew it, she ate half of the first layer fabric lol once she got through the first layer, all she’s been doing is walking around the house with the toy in her mouth. But now she’s tired and passed out on the couch from all of the fun. This toy won’t last long with a toy destroyer but it sure does give them something to do and it’s a cute toy. I do recommend!!

Last a while. Will be buying more toys soon.
Color: Consuela the Cactus - Large, Size: Large Dog
Best dog toy I have ever bought. I have three dogs, two at the time I bought this toy. It took them over a year to break through the first layer. The flower comes off first so be careful your dog doesn't swallow it. It still has the second layer so it still looks like a cactus. No stuffing to clean up when they tear into it, which makes it far less messy than other toys. One of my dogs is obsessed with fetch so I use it like a ball inside. The oval shape makes it hard to ensure when it bounces that it will bounce straight. It's bounced into walls and other stuff that I wasn't intending it to hit. Not much of a squeak so I can let them play with it for hours and I don't get annoyed with the noise. Great toy that lasts a while.

Nice Value
Color: Consuela the Cactus - Large, Size: Large Dog
Very cute! Its soft and feels like it is well made. It is a heavier toy and a tougher one. Not a plush toy. I will order again for our older dogs. Nice value for sure!
