Maintaining proper temperature is one of the most important factors in aquarium care. The Fluval E Heaters continuously monitor and display aquarium water temperature, ensuring the well-being of your aquarium inhabitants.

Simply the most technologically advanced submersible aquarium heaters available today, the Fluval E Series features VueTech technology. Its LCD display delivers peace of mind by continuously showing real time water temperatures. During normal operation the temperature display changes color if the aquarium water temperature varies from the pre-set temperature. Should external heat sources or other equipment cause the aquarium water temperature to rise or fall excessively the colored screen will flash, indicating a potential risk.

100 Watts: Suitable for aquariums up to 30 gallons

200 Watts: Suitable for aquariums up to 65 gallons

300 Watts: Suitable for aquariums up to 100 gallons

A few key facts to know about your Fluval E Heater:

Thermal Sensor:

The temperature sensing technology is as precise as an external probe!

The internal Thermal Sensor samples the actual water temperature directly through the glass of the heater tube rather than the air temperature within the tube, as is the case with standard bi-metallic strip thermostats. Since the Thermal Sensor actually reads the true water temperature, it is more accurate and reliable than conventional bi-metallic heaters.

Reliable and Precise Electronic Components:

Advanced Electronic Circuitry, no moving parts to wear out!

Since the FLUVAL E heater has no bi-metallic points, there are no moving parts to arc, corrode or wear. The thermostatic control of the heater is separated from the water thermal sensor, different from conventional bi-metallic heaters, where the sensor is directly built into the thermostat. It is therefore less affected by extraneous factors.

Four Sizes of the Fluval E HeaterSimple Installation Key FactsIts recommended to fill the aquarium with water that is close to the desired temperature you are trying to achieve.

-To ensure even and thorough distribution of warmed water and to provide an accurate temperature readings, the heater must be placed in close proximity to a source of water movement. Specifically, it should be placed at the rear of the aquarium, close to a filter or pumps water output. Water must at all times cover the heater at least up to the minimum water level indicated. Always maintain the water level in the aquarium to compensate for water loss due to evaporation. A unique heater feature is its Low-Flow Indicator. If you see LF on your heater screen, this simply means that you need to place the heater in an area with more water circulation.(Refer to Instruction Manual for more information)

1. Position the heater in the aquarium (vertically or horizontally) and press suction cups firmly against glass, to adhere to the aquarium wall. If rear glass mounting is not possible, use the side glass mounting adapter.

2. Allow heater to acclimatize in the aquarium water temperature for 20 minutes before plugging it into the electrical outlet.

3. After 20 minutes, plug in the heater and set the degree scale if necessary.

4. At each Power-on, the E Heater goes through an initial self-test procedure during which it carries out a self-diagnosis to check internal circuitry and sensors operation, followed by a period to verify the surrounding conditions.

WARNING: The heater must never be operated outside of the aquarium. If the water level falls below the minimum water level MIN, the thermostat can no longer "read the water temperature and therefore can no longer control the heating correctly. If it has to be taken out of the water or when transferring or changing the water, disconnect the heater from the power source and wait for at least 30 minutes to allow it to cool down.

Fluval E Series Heaters are guaranteed against defects in material or workmanship under normal aquarium usage and service for 5 years. We offer a 5 year guarantee on all non-replaceable parts which means that the heater will be repaired or replaced at the manufacturer's discretion, free of charge, when the complete heater is returned with proof of purchase and postage paid. This warranty does not apply to any heater that has been subjected to misuse, negligence, or tampering.
