Orlushy 150W Submersible Aquarium Heater with External Controller – 20-30 Gallon Tanks

Effortless Comfort for Your Aquarium

The Orlushy 150W Submersible Aquarium Heater is purpose-built for medium tanks in the 20-30 gallon range. At just 5.4 inches long, the heater tucks neatly behind décor or along the back pane, keeping a clean, uncluttered look while delivering steady warmth. This makes it suitable for a variety of setups, from a peaceful freshwater community tank to a compact betta enclosure, or a small reef-compatible mix where stable temperatures matter. The 150-watt rating balances quick heating with even distribution, helping you maintain a comfortable environment without frequent adjustments.

Smart safety you can rely on

Safety and durability are built in. The heater uses gray quartz glass, a tougher, explosion-resistant material than standard glass, designed to withstand typical aquarium conditions. A robust real-time water temperature sensing system continuously checks conditions and helps prevent abrupt swings that can stress aquatic life. When the water nears unsafe levels, the unit will shut down automatically if the temperature reaches about 95F, signaling with an EE code to avoid overheating.

• Automatic shutoff at 95F to prevent overheating.
• External controller reduces water exposure and extends life.
• 65F to 93F adjustable range with 1F steps.

Precise control at your fingertips

The external controller reduces the risk of water exposure to electronics and lets you adjust the set point without wet hands. The LED digital display keeps the current temperature in view, and you can fine-tune the target temperature from 65F to 93F, with 1F increments, ensuring precise control as seasons shift.

Real-world use and versatility

In daily use, you benefit from rapid heating that spreads warmth evenly through the water, helping maintain a stable habitat for fish, plants, and invertebrates. The compact size means it can be discreetly placed behind rockwork or filters, while the external controller keeps the setup approachable for ongoing tank maintenance. The 150W rating is designed to cover a 20-30 gallon volume, delivering quick yet even heating across the water column.

Everything you need in one package

Each pack includes a free thermometer to help calibrate measurements and verify readings as you dial in the right temperature. Orlushy backs the product with a 180-day warranty, offering supportive service if questions arise or a replacement is needed.
