Zoo Med ReptiTherm Under Tank Heater (U.T.H.), Large

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 regulate their bodily functions effectively.

The Zoo Med ReptiTherm Under Tank Heater replicates the natural warmth of sun-heated surfaces, providing a similar radiant heat effect. Ideal for terrestrial reptiles, especially nocturnal ones, it serves as either a main or supplementary heat source.

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

Size: 8" x 18"

Power: 24w

Usage Guidelines:

Attach the Zoo Med ReptiTherm Under Tank Heater to one side of the terrarium, either left or right, to establish a thermal gradient. It should span approximately half of the terrarium floor and be spacious enough for your reptile to lie on fully.

This heater is most effective with a shallow substrate layer (less than 2"). 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 reptile’s safety and maintain optimal temperatures, always pair the heat mat with a thermostat like the Zoo Med ReptiTemp Digital Thermostat to prevent overheating and burns.
