Reptile Systems Heating Mat 3.5W 15x15cm | Reptile Vivarium Heat Mat

The RS Heating Mat 3.5W is a slim, under-tank heating mat designed for small reptile and invertebrate enclosures. Measuring 15x15cm and drawing just 3.5W, it suits compact terrariums where precise, low-level belly heat is needed without cluttering the interior of the setup.

Designed to Protect Your Enclosure

The heating ink is distributed in a way that allows temperature to reduce gradually towards the edges of the mat, rather than cutting off sharply. This gradual thermal gradient reduces the stress placed on glass bases and lowers the risk of cracking — a genuine consideration when running heat mats under glass-bottomed terrariums.

Even Heat Across the Mat

Wide heating bands across the mat's surface work to maintain consistent temperature distribution, avoiding the hot spots that narrower element designs can produce. This means the warm zone your animal uses is reliably stable rather than patchy.

Installation and Safety

• Ultra-flat and thin profile — sits neatly under the tank without raising or tilting the enclosure
• Designed to be positioned under or to the side of the enclosure, keeping all electrical components outside the vivarium
• No exposed electrical wires within the heating surface itself
• Easy to install — full instructions included on the side panel

Creating a Thermal Gradient

Because the mat is installed externally — beneath or alongside the enclosure — it naturally allows animals to move away from the heat source into a cooler area of the enclosure. This is fundamental to thermoregulation and something keepers should always provide. Always use this mat in conjunction with a compatible thermostat to maintain safe, controlled temperatures.

A straightforward, reliable heat source for small enclosures — the RS Heating Mat 3.5W keeps the heat where it needs to be and the wiring where it belongs: outside the tank.
