Tetra Tetratec HT 100 Adjustable Heater

The Tetra HT heater is a powerful heater for aquariums.

An adjusted temperature is essential for the well-being of your fish and plants. Permanently too low or too high temperatures in the aquarium favour the development of diseases and minimise the willingness to spawn. Proper temperature control of the aquarium water is crucial for the well-being of your animals. Even some plants can change and take care of their growth considerably without the right temperature. A heating element should therefore be selected for each biotope with the right precision. Not only the size of the pool, but also the type of residents must be taken into account.

The Tetra HT control heater covers different power levels and has an adjustment button for preselecting the desired water temperature in the range from 19 ° C to 31 ° C in 0.5 ° C steps. The adjustable heater has a waterproof cap, which is why it is fully submersible. A control lamp shows the heating phase, the electronic switch offers maximum reliability and safety. The heating element has extra thick (2 mm) heat and impact resistant borosilicate glass tubes, as well as a double ceramic heating element for even heat conduction through the glass. Two strong adhesive suction cups with holding clips enable safe and easy attachment in the aquarium. Thanks to the long mains cable (1.6 m), it can be easily installed on the aquarium. The temperature settings are easy to read and therefore particularly user-friendly. The Tetra HT control heater is TÜV / GS tested and CE certified and has a 2 year guarantee.

Tip: Due to the submersibility, the control heater can also be installed in the filter tank, so that no devices are visible in the main tank!
