Zoo Med ReptiTherm Under Tank Heater (U.T.H.), Large
Reptiles, being ectothermic or "cold-blooded," rely on external heat sources like the Sun to regulate their body temperature for proper functioning.
The Zoo Med ReptiTherm Under Tank Heater replicates the natural warmth of sun-heated surfaces, providing a similar radiant heat effect. It serves as an excellent primary or secondary heat source for ground-dwelling reptiles, especially nocturnal species.
Zoo Med’s Under Tank Heaters are UL/cUL certified and feature a durable solid-state 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 (left or right) of the terrarium to establish a thermal gradient. It should span approximately half of the terrarium’s floor and be spacious enough for your reptile to rest fully on it.
This heat mat performs optimally with a thin substrate layer (less than 2"). For enclosures with deeper substrate, consider an overhead heating option like a halogen basking bulb or a ceramic heat emitter based on your setup needs.
To maintain safe temperatures and avoid burns, always pair your heat mat with a thermostat like the Zoo Med ReptiTemp Digital Thermostat!
