AquaHeat – Automatic Heater
The JUWEL heater safely and reliably ensures the correct temperature in your aquarium. Depending on room temperature and aquarium size, your JUWEL heater will achieve a water temperature of around +28°C.
Because it uses top-quality contacts and shock-proof, heat-resistant borosilicate glass (safety glass), JUWEL adjustable heaters meet the highest standards in both function and safety and, as you would expect, are TÜV/GS certified.
In all Rio, Vision, Trigon, Lido and Primo aquariums, the heaters are placed out of sight in the filter casing and are perfectly integrated in the water circulation of the Bioflow filter system.
This ensures an even, efficient distribution of heat throughout the tank.

The heater works steadily and keeps my aquarium at a consistent temperature. It’s quiet and doesn’t interfere with the filter flow. Installed easily in my Primo tank and has been reliable for over six months.
Sam Baker –
I appreciate how it’s hidden in the filter and doesn’t look out of place. The temperature stays stable even during temperature fluctuations in the room. A simple but effective solution.

After switching from an older heater, this one is more reliable and doesn’t overheat. The glass is sturdy and the unit feels well built. Works perfectly with my Bioflow filter.
