It simulates the warmth of a stone heated by the sun, which can retain heat for several hours in nature even after sunset. Some reptiles utilize this form of heat conduction for proper thermoregulation, which is essential for metabolism and digestion. The heater automatically turns off when the required temperature is reached, and all heating elements are completely enclosed in the housing. This prevents burns and overheating. The stone is coated with a special resin that is waterproof, non-toxic, and easy to clean, ensuring even heat distribution. The stone looks very natural and can be used in both wet or dry terrariums.
