Aquarium Heater - Eheim Thermocontrol e 300

Elevate your aquarium care with the Eheim Thermocontrol e 300 Aquarium Heater, designed for optimal performance in both freshwater and seawater environments. This state-of-the-art aquarium heater ensures your aquatic life enjoys a stable and precise temperature range from 20°C to 32°C, with a remarkable control accuracy of ±0.5°C. Ideal for aquariums up to approximately 1000 liters, it's perfect for tropical and subtropical fish that thrive at constant temperatures.

Featuring advanced electronic controls, this heater continuously maintains your set temperature, minimizing the need for frequent adjustments. The innovative glass coating serves multiple purposes: it increases the heating surface for optimal heat distribution, functions as a protective heat shield, and ensures that it's safe to the touch for your fish. The impact-resistant laboratory glass is designed to withstand extreme temperature fluctuations and is free from pollutants, ensuring a safe environment for your aquatic companions.

With a fully submersible design and dry-running protection (Thermo Safety Control), the Eheim Thermocontrol e 300 prioritizes reliability and safety. The heater includes a clear control lamp indicator, showing when heating is in progress or when the desired temperature has been reached.

Experience the quality and precision that come from made in Germany. The Eheim Thermocontrol e 300 Aquarium Heater is backed by a 3-year warranty, ensuring your investment in your aquarium’s health is protected. Make your aquatic world thrive with Smartfox NZ's trusted selection of high-quality aquarium products.

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.

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.
