QOSEREN Panel Heater Purchased for around 2000 yen. I kept it at home because the size didn't fit. 【Size】Approximately 42 x 28 cm Cord Length: Approximately 170 cm Panel heater, essential for cold winter days: A panel heater functions like underfloor heating for humans. It warms your stomach from the floor, raising your body temperature and aiding digestion after meals. Variable Temperature Heat Mat: With a dial, you can set your desired temperature within the range of ambient temperature to 45°C using self-temperature control. This product is attractive because you can freely adjust the temperature according to the type and condition of the reptile. PS: Since there is no temperature display function, we recommend using it with a thermometer. Ambient temperature to 45°C means that if the ambient temperature is 0°C, the panel heater can reach a temperature of 45°C, but if the ambient temperature is 20°C, the panel heater can only reach a temperature of 15°C. Convenient to install panel heater: It has a thin, mat-like shape and is lightweight and easy to handle. Since it is basically used outside the cage, there is no need to secure a cord hole or installation location, and there is no worry that reptiles will directly touch it and get burned. Use a panel heater to create a temperature gradient: When creating a temperature gradient, you can install the panel heater outside the cage. By placing it on the bottom of the cage for about 1/2 to 1/3 of the area, you can also create a temperature gradient. Reptile heater usable in a wide range: A panel heater to be used under the cage. In addition to reptiles, it also supports amphibians, small animals, and birds.
