JBL Protemp E300 External Heater

This in-line heater is seamlessly built into the hose of your external aquarium filter, eliminating the necessity for a heater inside the aquarium itself.
Installation is a breeze: simply cut the hose connected to your external filter that returns water to the aquarium, place the external heater in line, plug it in, and adjust to your desired water temperature.
Its integration within the filter system guarantees a consistent water temperature distribution, maintaining an accuracy of +/- 0.5 °C and a switching interval of 1.0 °C within the aquarium.

The heater features an LED display showing both the current and set temperatures. It comes with interchangeable hose fittings compatible with 12/16, 16/22, and 19/25 mm hoses, complete with hose locks. The total length of the unit is 30.5 cm.

Included in the package: 1 in-line heater rated at 300 W, suitable for aquariums ranging from 90-300 liters (80-120 cm), with hose connections for 12/16, 16/22, and 19/25 mm, along with a cleaning brush.
