Reptiles, being ectothermic or “cold-blooded,” rely on external heat sources rather than generating their own body warmth. They need environmental heat, much like sunlight, to maintain proper bodily functions.

The Zoo Med ReptiTherm Under Tank Heater (U.T.H.), Mini, replicates the natural warmth of sun-heated surfaces. Ideal as a primary or supplementary heat source, it suits terrestrial reptiles, especially nocturnal species.

Zoo Meds Under Tank Heaters are UL/cUL certified and feature a durable nichrome heating element for consistent performance.

Size: 4″ x 5″

Power: 4 watts

Usage Guidelines:

Attach the Zoo Med ReptiTherm U.T.H. to one side of the terrarium to establish a thermal gradient. It should span about half of the floor area and be sufficient to cover your reptiles full length.

This heater performs optimally with a substrate layer thinner than 2 inches. For enclosures with deeper substrate, consider an overhead heat option like a halogen basking bulb or a ceramic heat emitter, based on your setup needs.

To ensure your reptiles safety and maintain ideal temperatures, always pair the heat mat with a thermostat like the Zoo Med ReptiTemp Digital Thermostat to avoid overheating and burns.
