Collection: Aquarium Heaters

Shop aquarium heaters for maintaining suitable water temperatures in tropical and other heated aquarium setups. Explore submersible and other heater designs with different wattages, temperature ranges and control features for different tank volumes.

Choose heater capacity according to the aquarium size, desired temperature and typical room conditions rather than wattage alone. Install heaters according to the manufacturer instructions, keep them appropriately submerged where required and allow suitable cooling time before removing heated equipment from the water. Use a separate thermometer to regularly confirm the actual aquarium temperature.
