Zoo Med ReptiTherm Under Tank Heater Medium 16 Watts 8 x 12 in

Consistent 24-Hour Under Tank Heating for Mid-Size Reptile Enclosures

Zoo Med's ReptiTherm Under Tank Heater in Medium is an ideal primary or secondary heat source for tropical and temperate reptile species housed in mid-size enclosures. The Medium size - measuring 8 x 12 inches at 16 watts - delivers broad, consistent bottom warmth across a substantial heating surface, providing the thermal support reptiles need for healthy digestion, immune function, and thermoregulation around the clock.

All Zoo Med Under Tank Heaters are UL and cUL approved, with GS, TuV, and CE certification in Europe, providing the safety assurance that serious reptile keepers expect from a trusted heating product. The solid state nichrome heating element delivers consistent, reliable warmth, and the heater permanently adheres to the terrarium glass to form a solid bond for optimum heat transfer.

The ReptiTherm Medium bridges the gap between the Small (6 x 8 inches, 8 watts) and Large (8 x 18 inches, 24 watts) sizes, making it the right choice for mid-size enclosures where more heating coverage is needed without stepping up to the full large format.

Quick Product Snapshot

Material and Design Breakdown

The ReptiTherm Medium features a solid state nichrome heating element encased in a durable housing that permanently adheres to the exterior glass bottom of the terrarium. The direct glass contact maximizes heat transfer efficiency, ensuring the 16-watt element delivers consistent warmth across the full 8 x 12 inch heating surface. The medium footprint creates a substantial warm zone suitable for mid-size enclosures housing a wide range of reptile species.

Setup and Compatibility Guidance

Attach the ReptiTherm Medium to the exterior bottom of the terrarium, positioning it along one end of the enclosure to create a defined warm zone. This allows the reptile to thermoregulate by moving freely between the warm and cool sides of the habitat. Always use with a thermostat or temperature controller to maintain safe and consistent temperatures. Suitable for tropical and temperate reptile species in mid-size enclosures.
