Eheim Thermocontrol e 300 Heater

The obvious ideas are often the best. This also applies to the aquarium heating element. It is simply hung in the water and heats it up. The principle is the same as it was decades ago. But in the meantime, the EHEIM controller heater has become an ultra-modern thermal device. The temperature can be set precisely and is measured even more precisely and kept more constant by the electronics. The coating made of special laboratory glass increases the heating surface, serves as a heat shield and ensures even heat emission.

Precision, comfort, quality and safety "Made in Germany".

As you know, fish from tropical and subtropical waters need a certain constant water temperature. Before the engineer Eugen Jäger invented the aquarium heater decades ago, there was no really satisfactory solution to produce the appropriate water temperature. They dealt with complicated and sometimes curious methods. Some put the aquarium in the sun or by the heater or stove.
The EHEIM thermocontrol aquarium control heater is a further development of the legendary heating element and thermocontrol-e is the latest electronically controlled variant.
The temperature can be precisely adjusted from 20 to 32 °C. The control accuracy is ± 0.5 °C.
The heat is kept constant. A control lamp indicates the heating function.
The heater is absolutely waterproof, can be fully immersed, has dry run protection (Thermo Safety Control) and is suitable for fresh and marine water. One of the most important innovations is the glass coating:
• It increases the heating surface,
• compresses the heat, ensures optimum, uniform heat output and
• forms a heat shield (the aquarium inhabitants do not mind touching it).

The coating is made of special laboratory glass. This was created for research purposes. It is, therefore, free of pollutants that could be released into the water. Chemical and biological substances do not attack them. There are no cracks and hairline cracks through which condensation water could pass. It is impact resistant. And even extreme temperature fluctuations, such as those that may occur during water changes, do not affect this glass.

Stylish and affordable!
Color: Grey, Size: 4 Pack, Color: Grey, Size: 4 Pack
These shelves are rey stylish, light and durable! The set came with everything needed to install. The color is just as described. Price is steal and these shelves can definitely be used anywhere throughout the house. I did give it only 4 stars because as you can see in the photos, the underneath was not completely finished. Decided to keep because the price was unbeatable.

Mounting system doesn’t align on one of three shelves.
Color: Walnut, Size: 3 Pack
Nice shelves. Install was super easy except on one of the three shelves. The main mounting shelf holes were off so the shelf will not slip onto horizontal mounting poles unless I modify the shelf. So a 20 minute job becomes a two hour job. The mounting system does appear very sturdy just not aligned.
