Quick Product Snapshot

Material and Design Breakdown

The ReptiTherm Large 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 24-watt element delivers consistent warmth across the full 8 x 18 inch heating surface. The large footprint creates a broad warm zone suitable for bigger enclosures housing larger reptile species that require more floor space to thermoregulate effectively.

Setup and Compatibility Guidance

Attach the ReptiTherm Large 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 large enclosures.
