Oase HeatUp Aquarium Heater

The OASE HeatUp Aquarium Heater features an advanced patented temperature control system that ensures exact regulation of your aquarium’s water temperature. Equipped with a sensitive bi-metal sensor, it delivers consistent warmth with minimal fluctuations. Designed for both freshwater and marine tanks, this durable heater comes in a range of wattages from 25w to 300w, allowing you to match your tank size perfectly. It fits seamlessly with OASE FiltoSmart and BioMaster filters for hassle-free installation outside the tank, while also including a mounting holder for internal placement. Backed by a 3-year warranty, the HeatUp heater guarantees reliable performance you can trust.

As a general guideline, we recommend a minimum of 1 watt of heating for every litre of aquarium water to ensure your tank maintains a stable and comfortable temperature. For example, a 50-litre aquarium will perform best with a 50-watt heater, providing consistent warmth without overworking the unit. Choosing the right wattage helps protect your aquatic life by preventing temperature fluctuations, promoting a healthier environment for your fish and plants. This simple rule makes selecting the perfect heater easy, ensuring efficient energy use and reliable temperature control tailored to your aquarium size.
