The Jolly Preset heaters are designed for small freshwater or marine aquariums. Their plastic body is unbreakable and ensures a long lifespan. Thanks to this, these heaters can be placed under the gravel, making them suitable also for turtle or reptile tanks.
The Jolly heater operates when submerged in water. It stops heating only when it is removed from the water or unplugged. The thermal protection stops the operation when the heater is no longer submerged, preventing overheating (the LED indicator turns off even if the heater is plugged in).
The heating power depends on several conditions: water volume, room temperature, open or closed aquarium.
