Your cart is empty.The HeatUp line of aquarium heaters are a reliable way of creating and maintaining uniform temperature levels for your freshwater or marine aquarium environment. The robust double insulated quartz glass tube provides additional safety for aquarium use and is able to withstand greater temperature fluctuations than glass. The HeatUp temperature scale can be adjusted between 66°F - 90°F. The control system has a patented secondary knob for accurate readjustment of the temperature (+/- 2°F) and can be adjusted using the included post calibration tool. Temperature levels are monitored and controlled by bi-metal technology for automated heating with a thermal shutoff switch for added protection. Additionally, the heating function is displayed via the activated control light. Integrate this heater into the BioMaster 250 to combine filtration and heating into one location. Integrating the heater reduces the amount of additional equipment seen in the aquarium. The optimal aquarium size for this heater is 40 gallons. The included holder with suction cups can be used to install the heater to the side of the aquarium. Designed using German engineering and manufactured in Italy, this energy efficient heater is protected with a 3 year warranty.

Very accurate heater. Set to 80 degrees and my test thermometer shows 80.5 degrees in my 29 gallon tank. No calibration needed. I also like the size of the heater. Longevity speaking only time will tell.

This is a quality heater. German engineering sets it apart from the typical Chinese knockoffs.I will track its perfomance against the Eheim heaters I am using..

Fits the filter, was disappointed that the oase didn't come with it already considering the price! The heater should come equipped with the canister filter.

Oase is a premium European brand. I'm glad we can get them here in the States
