Terrarium Heat Mat Hagen Exo Terra PT2859 – Substrate Heating Pad for Reptiles

The Hagen Exo Terra PT2859 Terrarium Heat Mat is a flat substrate heating pad designed to supply gentle, localized warmth for reptiles and amphibians. Intended for placement beneath or alongside the terrarium floor, the mat provides a stable heat source to help create temperature gradients required for thermoregulation, promote activity and digestion, and support conditions for egg incubation where appropriate. The low-profile design integrates unobtrusively with substrate layers and works with a range of enclosure sizes and substrates.

Advantages

The heating pad delivers even surface warming to specific areas of the terrarium without occupying internal space, enabling natural behavioral thermoregulation. Its flat construction reduces the risk of uneven hot spots when used correctly and is compatible with multiple substrate types. The mat supports controlled warming of incubation sites and resting areas while remaining easy to install and clean around when the enclosure is maintained.

Suitable for

• Providing a warm area for reptiles and amphibians to thermoregulate
• Creating a localized heat spot for digestion and activity
• Supporting substrate-warmed egg incubation (when used with appropriate monitoring)
• Maintaining a warm hide or basking zone without overhead heat sources

Key specifications

• Flat heating pad format for placement under or alongside the terrarium floor
• Designed for substrate heating to create localized warm zones
• Low-profile construction to remain discreet under substrate
• Suitable for use with a variety of substrates and enclosure layouts
• Provides steady, localized heat to support animal thermoregulation

How to use

Place the Exo Terra PT2859 heat mat beneath or beside the terrarium floor in the location where a warm area is required. Cover the mat with the chosen substrate, ensuring the mat is fully supported and does not fold or crease. Connect the mat to a suitable thermostat or temperature controller to monitor and regulate surface temperatures; avoid running the mat directly without temperature regulation for sensitive species or incubation. Check temperatures at substrate level with a reliable probe thermometer and adjust placement or thermostat settings to establish an appropriate gradient. Inspect the mat and surrounding substrate regularly for wear or hot spots.

Usage recommendations

Use a thermostat or temperature controller to maintain safe, species-appropriate temperatures and prevent overheating. Do not place the mat inside the enclosure or in direct contact with water; ensure electrical connections remain dry. For egg incubation or sensitive species, monitor humidity and temperature closely and combine substrate heating with external sensing to achieve stable conditions.
