The Fluval E-Series Aquarium Heater is an advanced electronic heater designed to provide precise and reliable temperature control for freshwater and marine aquariums. Featuring an integrated thermostat, dual temperature sensors and a clear LCD display, it continuously monitors and adjusts water temperature to maintain stable conditions for your fish.

Each heater displays real-time water temperature via the built-in LCD screen and uses the Fluval VueTech Alert System to indicate temperature fluctuations. The colour-changing display alerts you if the water is too hot or too cold in relation to your pre-set temperature. Dual sensors also monitor water flow to help confirm correct positioning and effective heat distribution.

An integrated fish guard helps reduce the risk of accidental contact, while heavy-duty suction cups and a slim mounting bracket provide secure installation within the aquarium. The simple toggle control allows precise temperature adjustment to suit your setup.
