This 50 W heater is for keepers who need to hold a steady water temperature in a small tank without monitoring it by hand. The built-in thermostat switches the heater on when the water cools below the set point, so the temperature stays within the chosen range between 18 and 34 °C. It is sold as a complete set with mounting hardware.
Why it matters
- Automatic temperature control: the thermostat switches the heater on when water temperature drops below the setting and holds the chosen value across the 18–34 °C range.
- Fully submersible: IPX8 rating, which the manufacturer states allows continuous operation under water, provided the water level is at least 15 cm.
- Easy to read and adjust: a clear temperature indicator and a large regulator knob make setting the target quick, and an indicator LED shows when the heater is running.
- Ready to install: suction cup mounts with holders are included, and the set comes with a 100 cm power cable rated for 230 V.

What it works with

The heater suits freshwater and marine aquariums, and the manufacturer states it complies with CE and IP requirements.
