Provide a stable, stress-free climate for your fish and corals with the OASE HeatUp 100 Watt Aquarium Heater. Engineered in Germany and manufactured to strict standards in Italy, this fully submersible adjustable thermostat heater delivers precise, automated warmth to prevent dangerous temperature swings.
Best suited for aquariums up to 30 gallons (100 Liters), its compact profile can be mounted traditionally inside your main tank display or tucked completely out of sight by integrating it into a compatible OASE external canister filter.
📐 Technical Specifications & Calibration
Wattage: 100 Watts
Dimensions: 245 mm long x 23 mm diameter (approx. 9.6” x 0.9”)
Temperature Range: 66°F to 90°F (18°C to 32°C)
Power Cable Length: 1.5 meters (4.9 ft)
Water Compatibility: Fresh and Marine / Saltwater environments
🌟 Standout Benefits
Patented Recalibration System: No more guessing games with inaccurate dials. The HeatUp 100 features a patented manual adjustment tool that lets you recalibrate the internal temperature scale by +/- 3°C (+/- 6°F) to match your independent digital thermometer perfectly.
Thermal Shock-Resistant Quartz: Encased in a double-insulated, high-quality quartz glass tube. This robust housing easily handles severe thermal fluctuations and minor bumps that would shatter cheaper glass heaters.
Seamless Filter Integration: Clear clutter out of your main display tank. This 100W model is specifically designed to slide directly into the integrated heating chambers of the OASE BioMaster 250 or FiltoSmart 100 external filters.
Smart Mechanical Safety: Utilizing reliable bi-metal technology for uniform heat output, the heater also features a built-in dry-run safety shutoff switch that cuts power instantly if the water level drops too low.
At-A-Glance Status Indicator: A clear, built-in LED control light glows bright amber while the unit is actively heating, giving you a visual confirmation of operation without messing with cables.

1x OASE HeatUp 100W Adjustable Heater
