Key specifications
Power: 300 W
Heating element length: 27 cm
Design: immersion-style electric heater for direct water heating
Intended use: temporary and portable heating for aquaria and small tanks
How to use
Submerge the heating element fully in the water according to the manufacturer's safe immersion depth and ensure the electrical connection remains dry and protected. Position the heater so it remains stable and away from direct contact with delicate specimens or substrate. Connect to a suitable power source and monitor the water temperature with a separate thermometer, adjusting positioning or power intervals as needed. Use the heater only for the short-term heating tasks it was designed for and avoid leaving it unattended in permanent installations if it is not rated for continuous use.
Usage recommendations
Use a separate, accurate thermometer to verify water temperature and avoid overheating. Do not operate the heater out of water; always ensure full immersion of the heating element before switching on. Regularly inspect the unit for visible damage and follow all electrical safety guidelines, including using a residual current device (RCD) where appropriate.
