OASE HeatUp 100 Aquarium Heater

The OASE HeatUp 100 delivers commercial-grade climate control for professional aquascapes, tropical community tanks, and marine ecosystems up to 100 litres. Engineered in Germany and meticulously manufactured in Italy, this 100-watt adjustable heater eliminates dangerous temperature fluctuations that threaten sensitive fish, corals, and aquatic plants. Constructed with thick, double-insulated quartz glass, the HeatUp 100 provides superior thermal shock resistance, allowing it to withstand major temperature drops and continuous underwater stress far better than conventional glass heaters.

Equipped with high-sensitivity bimetal thermostat technology, the unit monitors and adjusts heat levels automatically for uniform climate stability. A patented secondary calibration dial provides the unique ability to manually adjust the system scale by +/- 3°C, ensuring your digital monitoring matches the hardware perfectly. Built for dual-purpose versatility, the HeatUp 100 functions flawlessly as a standalone unit or locks directly into the internal heater chambers of OASE BioPlus, FiltoSmart, and BioMaster filter systems for a completely concealed, hardware-free layout.
