Reptiles and amphibians are cold-blooded and naturally bask on sun-warmed surfaces in their habitats to regulate their body temperature. The Exo Terra Heat Mat creates a thermal gradient, mimicking the sun-heated surfaces for your reptile's comfort. The Self-regulating Heat Mat allows for uniform conductive heating, and thus eliminates concentrated hotspots, fostering optimal thermoregulation in reptiles, amphibians, and invertebrates. This is crucial to enhance their metabolism, appetite, digestion, and overall physical activity. The superior PTC Carbon Fiber heating technology incorporates enhanced safety features like an automatic fail-safe mechanism, rapid warm-up capabilities, and a self-regulating maximum temperature for optimal performance and safety. The Exo Terra Heat Mat is remarkably energy efficient, boasting an electrothermal conversion efficiency exceeding 95%, providing increased heat output at equivalent wattage levels. The Heat Mat serves as an optimal 24-hour primary or secondary heat source for reptiles, amphibians, and invertebrates. It is particularly indispensable as a nighttime heat source for various species. The Terrarium Substrate Heater permanently adheres to the terrarium, forming a solid bond for optimal heat transfer. We recommend to combine the conductive heat of our Heat Mat with the radiant infrared-A heat of our Exo Terra Basking Spots. The Solar Power Density of our Basking Spots in combination with the conductive heat of our Heat Mat, allows your reptiles to thermoregulate their body temperature to achieve an optimal temperature for enhanced activity and healthy digestion of their food items. The small portion of UVA rays of the Basking Spot, also contributes to their physiological well-being and stimulates breeding behavior. Can be used with an Exo Terra Thermostat and/or in conjunction with supplementary heat sources, catering to the specific temperature needs of high-temperature species.
