Simple ideas often turn out to be the most effective. Take, for instance, the aquarium heater designed as a rod. This heating rod is easily suspended in the water to warm it. While the concept has remained unchanged for decades, significant advancements have been made over time. Today, the EHEIM adjustable heater represents a state-of-the-art electronic heating device that utilizes the latest technology. Its jacket, crafted from specialized laboratory glass, enhances the heating surface, acts as a heat shield, and guarantees optimal, uniform heat distribution. Whether you need to heat a 20-liter or a 1000-liter aquarium, you can choose from 9 available sizes.

  • Temperature control precision ± 0.5 °C
  • Heat maintained at a consistent level
  • Heating function indicated by a control lamp
  • Completely submersible (watertight)
  • Features automatic dry run shut-off (Thermo Safety Control)
  • A glass jacket enhances the heating surface and guarantees optimal, even heat distribution
  • Convenient cable length of approximately 170 cm
  • Includes double suction cup holder
  • 9 sizes available for aquariums ranging from 20 to 1000 liters
  • Suitable for both freshwater and marine environments
  • Precision, user-friendliness, quality, and safety “Made in Germany”

The EHEIM aquarium heater is an advancement of the iconic heating rod. The temperature can be set with precision between 18 and 34 °C and can be recalibrated if necessary (±2°). It maintains a constant temperature level, and its heating function is signaled by a control lamp. The rod is fully watertight, can be completely submerged, and includes an automatic dry run shut-off feature (Thermo Safety Control), making it suitable for both freshwater and saltwater aquariums.

One of the most significant innovations is the glass jacket:

  • It expands the heating surface,
  • Concentrates the heat to ensure optimal, even heat distribution, and
  • Acts as a heat shield (safe for your aquatic life).

This jacket is made from specialized laboratory glass, designed for research applications. Therefore, it is free from harmful substances that could leach into the water. It is resistant to both chemical and biological agents, free from fissures or fine cracks that could allow moisture to seep in. Even extreme temperature fluctuations that may occur during water changes will not damage this glass.

Good stuff
Size: 50 sqft, Size: 50 sqft
Good stuff. I did a lot of work on my 91 Toyota Land Cruiser 3FE. I did the inside and outside doors, as well as the under-hood area, with some extra work. I like this stuff. It sticks down good but you have to clean your surface so there's a good grip. I think these are going to do well for noise cancellation. The deadening material does well with absorbing vibrations too. But the install roller tools it will come in handy. Trust me trying to do it by hand is not worth it.

Good material but bites back
Size: 20 sqft
Very good product for my rear trunk and backseat on my mustang. I would recommend some type of gloves due to the foil itself when placing down will cut up your hands and fingers. Overall good product for its price.

Great product for the price
Model: 197mil 31 sqft Car Sound Deadening Mat, Model: 197mil 31 sqft Car Sound Deadening Mat
This sound deading material has a good thickness to it. It seems like the cab of the truck is cooler inside from the heat of the motor. It’s easy to install and easy to cut with a razor blade. The quality it’s an 8/10 the only complaint I have is the adhesion will stick to your fingers if you are touching it when you peel the backing paper off. It stick to the truck great tho. It covered the entire floor and back wall of a single cab truck.
