Maintain the perfect environment for your tropical, freshwater, or marine fish with the Interpet Deltatherm Heater. This high-performing, fully submersible unit provides precise and reliable temperature control, ensuring your aquatic pets thrive. Constructed with heat and shock-resistant glass, this heater is designed for safety and durability.
Key Features & BenefitsFor accurate temperature control, the heater should be placed diagonally within the aquarium, rather than vertically or horizontally, as the thermostat is located at the top of the unit. Before installation, check that the glass tube is undamaged and that the mains supply voltage matches the heater's requirement. Fix the suckers to the heater and adjust the temperature dial to your desired setting. The integral thermostat will automatically turn the heater off once the target temperature is reached, which is indicated by the red light turning off.
Ensure optimal conditions for your aquatic life with this reliable 150W Interpet heater, perfectly sized for aquariums up to 135 litres.
