About this product
The Orlushy aquarium heater is a 300W submersible model with a nickel-chromium heating wire and a separate thermometer. It suits small fish tanks, aquariums and turtle tanks, and the model measures 27.9 x 3 x 3 cm. The heater comes in six sizes, and this version is the C300.
What tank size and setup the heater suits
This heater is intended by the maker for aquariums, turtle tanks and small fish tanks, and the wattage should be picked according to the size chart. Before buying, check that your tank falls within that small-tank range and that the 300W model is the one the chart lists for it.
The heater must be fully underwater before you plug it in. The model is 27.9 cm long and 3 cm in diameter, so the water depth and the space inside the tank need to accommodate that length.
Submerging and setting the heater
According to the manufacturer, the heater needs to be 100% submerged in water before it is plugged in. When you clean the tank or change the water, unplug it and let it cool for 10 to 20 minutes, then take it out.
The heater uses stair-shape heating. A red light shows intermittent heating toward the set temperature, and a green light shows that heating has stopped and the temperature is being held.
Heating parts and indicator lights
The outer shell is made of heat-resistant ABS, and the heating rod is a nickel-chromium wire covered in non-corrosive quartz glass. Those materials form the parts that sit in the water.
A red light means the heater is heating in intervals to reach the set temperature. When the green light comes on, heating has stopped and the heater is holding the temperature.
Six sizes in the Orlushy range
The Orlushy heater is offered in six different sizes, and this page covers the C300. The model is rated at 300W.
