The JUWEL heater ensures the correct temperature in your aquarium safely and reliably. Depending on the room temperature and the size of the aquarium, the JUWEL heater will achieve a water temperature of approximately +28°C.

Because it uses high-quality connectors and shock-resistant borosilicate glass (safety glass), JUWEL adjustable heaters meet the highest standards in terms of functionality and safety, and as expected, they are TÜV/GS certified.

In all Rio, Vision, Trigon, Lido, and Primo aquariums, the heaters are discreetly placed inside the filter casing and are fully integrated into the water cycle of the Bioflow filter system.

This ensures an even and effective distribution of heat in your aquarium.
