Fluval E200 Aquarium Heater, Black for Up to 246 L with LCD Display and VueTech Alerts

Fluval E200 is an electronic aquarium heater designed to heat aquariums up to 65 gallons, with a real-time LCD temperature display and VueTech alerts.

• For aquariums up to 65 gallons — choose a heater sized for tanks within this capacity.
• Continuously displayed water temperature — see current readings on the LCD screen.
• VueTech color alerts — spot temperature changes from the preset level.
• 0.5° temperature adjustments — set the target temperature in small increments.
• Dual sensors and an integrated fish guard — monitor water temperature while keeping fish and invertebrates from direct contact with the heater core.

Stable aquarium water temperature is important to the conditions your fish and invertebrates live in. The Fluval E200 combines heating with a visible temperature readout, so you can check the water at a glance and notice changes without relying on a separate reading to see the current temperature. Its adjustable mounting setup also suits aquarium installations where access to the heater matters, including marine aquariums with a sump.

How does the Fluval E200 show temperature changes?

The LCD screen displays the aquarium’s real-time water temperature and changes color when the reading varies by 1°C (2°F) or more from the preset temperature. If the water shifts beyond 3°C (5.5°F), the screen flashes to signal a potential temperature risk. The display can show temperature in Celsius, and the heater’s microprocessor technology uses dual sensors to provide ongoing readings.

• The temperature-setting control uses an adjustment lever.
• Temperature can be measured in Celsius as an alternative display option.
• VueTech alerts can indicate changes caused by external heat sources or other equipment, including chillers.

What aquarium setups can it fit?

The Fluval E200 is made for aquariums up to 65 gallons and can also be attached in a marine aquarium sump. A slim-profile mounting bracket secures the heater, while the heater itself can be adjusted or removed without taking the mounted bracket off. This arrangement gives you access to the heater without removing its bracket from the aquarium.

• The mounting bracket can be attached to or removed from the heater.
• An integrated fish guard keeps fish and invertebrates from directly contacting the heater core.
• The glass sleeve is protected against shocks from large fish species.

How should the Fluval E200 be handled and used?

Operate the heater only while it is in the aquarium and keep the water above the marked MIN level. Below that minimum, the thermostat cannot read the water temperature correctly or control heating as intended. The heater also includes a safety shut-off as part of its heating system.

• Before removing the heater for a water change or transfer, disconnect it from the power source.
• After disconnecting it, allow at least 30 minutes for the heater to cool before taking it out of the water.
• Fast-heating technology is part of the E Series heater design.

The Fluval E200 is suited to aquarium keepers with tanks up to 65 gallons who want the water temperature visible on the heater and alerts when readings move from the set point. Its bracket and sump attachment option also suit installations where the heater needs to be positioned within a marine aquarium sump. It is designed for submerged aquarium use, with a minimum water level that must be maintained.
