Fluval T-Series Submersible Heaters

An adjustable submersible heater with a dial that is easy to grip and set, and an indicator ring you can read from anywhere in the room.

Key features

• Easy-grip temperature dial, meant to be set once and left alone
• 360 degree indicator light ring, visible from any angle, so a glance tells you whether the heater is calling for power
• Switches itself off when it is not in water, which protects the unit if the level drops during maintenance
• Sold in several wattages — match the wattage to your tank volume, or ask us and we will size it for you
• Suitable for fresh and salt water

Install it fully submerged and in good flow, near a filter outlet or powerhead, so the thermostat reads the whole tank rather than a still pocket of warm water. Pair it with a separate thermometer at the opposite end of the tank. The rest of the range is in Fluval.
