The Dupla Therm heating systems (ground heating with a low voltage of 24V) and the ground convector Dupla Thermik Set developed by Dupla play a crucial role in ensuring ideal living conditions in the aquarium. By upwelling the heated water on the ground, the heating cable on the aquarium bed integrates the bed into the chemical and physical cycle of the entire aquarium. This ideal heating system for aquaria meets not just one but several requirements:
1. As in natural waters, the ground is also heated. If only the aquarium water is heated, as is the case when using a bar heater, the water may be warm but the aquarium bed will still have room temperature, thus making plants suffer from the notorious “cold feet”.
2. A ground heating system copies the groundwater current found in natural waters, the roots are supplied with nutrients, and the substances given off by the roots are carried off.
3. A stable redox potential in the ground, preventing it from turning black. In connection with Dupla Root (see Dupla fertilising system), the plants are supplied with an ideal iron depot such as that of tropical waters.
4. Complete safety for man and animal, even when damaged.
The two heating systems differ in that Dupla Therm Set heats the entire aquarium, the Dupla Thermik Set, on the other hand, only heats the aquarium bed while the aquarium itself is heated by a water heater.
