Description
xMeet the Orlushy 25W Submersible Aquarium Heater, a compact heating solution designed for small tanks from 1 to 6 gallons. At 4.7 inches long, it sits neatly behind decor and remains discreet while delivering consistent warmth for freshwater and saltwater setups. In fish-only nano tanks, it can be fully submerged vertically; in turtle or other larger habitats, it offers horizontal placement to suit the space.
Precise, automatic temperature control keeps your tank comfortable without guesswork. The heater ships with a preset 78°F and an accuracy of ±3°F. It uses a visible heating cycle: the red indicator lights up to begin warming, then steps down as the water approaches the target, and the green indicator signals stable temperature at 78°F.
Durable construction combines a heat-resistant ABS outer shell with a nickel-chromium heating wire for faster warming and a non-corrosive quartz glass interior. The result is a compact device designed to withstand regular use without deformation or corrosion.
Safety and maintenance are straightforward. Ensure the heater is 100% submerged before powering on. To clean or change water, unplug and let the unit cool for 10–20 minutes before removal. Orlushy backs this heater with a 1-year warranty and responsive support.
Why a small-tank heater makes sense
In compact tanks, a reliable heater helps keep the water steady, supporting predictable behavior and a stable environment. The 25W rating targets 1–6 gallons, which is common for betta bowls, nano reefs, or planted tanks, and other compact setups. The unobtrusive form lets you preserve the look of your aquarium while maintaining consistent warmth.
