OASE HeatUp 150 Adjustable Aquarium Heater (150W)

Achieve optimal thermal stability in your aquatic environment with the OASE HeatUp 150. Expertly engineered in Germany and precision-manufactured in Italy, this premium 150-watt submersible thermostat heater delivers highly responsive, reliable climate control for both freshwater and marine aquariums up to 150 litres. Built with heavy-duty, double-insulated quartz glass, the HeatUp 150 offers robust thermal-shock resistance, allowing it to easily handle major temperature drops, shifts, and continuous underwater operational demands.

The OASE HeatUp 150 utilizes high-sensitivity bimetal thermostat technology to ensure consistent, automated heat distribution throughout your tank. For advanced precision, a patented secondary calibration collar allows hobbyists to manually adjust the system scale by +/- 3°C to align exactly with independent digital probes. Designed with practical system integration in mind, this slimline heater can be used as a standalone unit with the included suction bracket, or it can be mounted directly inside the integrated heater chambers of OASE BioMaster 250 and 350 external filters to keep your main aquascape entirely free of visible hardware.
