Heating Cable Hagen ExoTerra 15W for Terrarium Heating

The Hagen ExoTerra 15W heating cable for terrarium heating is a low-wattage, flexible heat source designed to provide localized warmth in reptile and amphibian enclosures. The cable delivers continuous, gentle heat that can be positioned to create warm spots, used under substrate for mild bottom heating, or applied to surfaces that require targeted warming. Its low power output makes it suitable for small to medium setups or for supplementing primary heat sources to help animals thermoregulate.

Advantages

The heating cable offers a flexible and discreet heating solution that adapts to various terrarium layouts. Its low 15W output ensures energy-efficient, steady warmth without large temperature fluctuations. The cable’s flexibility allows precise placement for creating thermal gradients or localized hot spots. It can be used under substrate or along surfaces to maintain stable microclimates in specific areas of the enclosure.

Suitable for

• Creating warm basking or resting spots for reptiles and amphibians
• Under-substrate heating for species that prefer mild bottom warmth
• Supplemental surface warming where a heat mat or lamp is not appropriate
• Small terrariums or localized heating zones within larger enclosures

Key specifications

• Power output: 15 watts
• Flexible cable design for custom placement
• Continuous low-level heat suitable for localized warming
• Intended for use inside terrarium environments

How to use

Place the heating cable in the terrarium according to the intended use: run it under a shallow layer of substrate for gentle bottom heating, attach it along a surface to create a warm spot, or coil it in a hidden area to form a localized heat source. Ensure the cable is positioned away from direct contact with animals where possible, and secure it to prevent shifting. Use an appropriate thermostat or temperature controller to monitor and regulate surface and substrate temperatures and to maintain safe, species-appropriate thermal gradients within the enclosure.

Usage recommendations

Monitor temperatures with a reliable thermometer and, if available, a thermostat designed for terrarium heating. Combine the cable with hides, shelters, and gradients so animals can move between warmer and cooler zones. Avoid placing the cable directly under deep substrate layers or bedding that could over-insulate and cause excessive heat buildup.
