Product description

This 25W heater suits keepers of small freshwater and marine aquariums with a capacity up to 20 L who need a simple way to set and hold water temperature. It is fully submersible, so it can sit directly in the tank water.

Why it matters

  • Dial thermostat: a precise adjustment knob sets the target temperature, and a readable scale shows the chosen value.
  • Indicator lamp: a built-in light shows whether the heater is currently switched on.
  • Full submersion: the unit is designed to be fully immersed, which allows placement inside the tank.
  • Suction cups included: the set comes with suction cups for fixing the heater to the aquarium wall.
