RS Electrical Aquarium Heaters

RS Electrical aquarium heaters are affordable, fully submersible automatic glass heaters equipped with built-in thermostats to maintain stable water temperatures. They typically feature an adjustable temperature dial ranging from 18°C to 32°C, double glass protection for durability, and an auto on/off status indicator light.

Crucial Safety and Installation Guidelines

Submerge Fully: Always completely submerge the heater in water before plugging it in to avoid cracking the glass or damaging the internal thermostat.

Water Circulation: Install the heater near a filter output or wavemaker to distribute heat evenly across the tank.

Cool Down Period: Turn off the power and wait at least 10–15 minutes before taking the unit out during water changes.
