ProRep Cloth Element Heat Mat 35x11cm 43W | Reptile Vivarium Heat Mat

The PR Cloth Element Heat Mat (35x11) 43W is a large-format undertank and vivarium heating mat designed for reptiles, amphibians, and invertebrates. It emits ultra-long wavelength infrared heat that is absorbed directly by the animal and the surrounding cage furniture, replicating the way solar radiation warms basking animals and substrate in the wild — raising body temperature without necessarily increasing the ambient air temperature of the enclosure.

How It Heats

Rather than heating the air, this mat works by warming surfaces and animals in direct contact or proximity, much as sun-warmed ground provides passive belly heat for terrestrial species. This makes it particularly effective as a background or substrate heat source, giving animals the opportunity to thermoregulate by moving toward or away from the heated area.

Sizing and Installation

At 35x11cm and rated at 43W, this is a larger heat mat suited to bigger vivariums and enclosures where a substantial heated zone is needed. The appropriate size and placement — whether positioned underneath the enclosure or along an internal wall — will depend on the species being kept, the enclosure design, and any supplementary heating already in use. Always follow the manufacturer's safety and installation guidance carefully.

Thermostat Use — Essential

A thermostat must be used with this heat mat at all times. Without one, surface temperatures cannot be reliably controlled, creating a risk of overheating for the animal and the enclosure. A mat thermostat or pulse-proportional thermostat is recommended depending on your setup.

Species Suitability

• Suitable for reptiles, amphibians, and invertebrates
• Best suited to species that benefit from gentle background warmth or belly heat rather than intense localised basking spots
• Species with higher temperature requirements or that need a distinct basking zone may require supplementary heating in addition to this mat
• Particularly well-suited to nocturnal species, burrowing species, and many invertebrate setups

Used correctly alongside a reliable thermostat, the PR Cloth Element Heat Mat (35x11) 43W gives keepers a straightforward and effective way to deliver naturalistic infrared warmth across a generous area of the enclosure floor or wall.
