It is designed to provide steady, uniform conductive heat beneath the substrate — replicating the warmth of sun-heated ground surfaces that reptiles, amphibians, and invertebrates rely on to regulate their body temperature. Suitable as a primary or secondary 24-hour heat source depending on the species being kept, and particularly useful as a nighttime heat source where overhead lighting is switched off.\u003c\/p\u003e\u003ch3\u003ePTC Carbon Fibre Heating Technology\u003c\/h3\u003e\u003cp\u003ePTC (Positive Temperature Coefficient) carbon fibre heating means the mat self-regulates its maximum output temperature, reducing the risk of overheating. The electrothermal conversion efficiency exceeds 95%, delivering strong heat output relative to the wattage drawn. An automatic fail-safe mechanism is built in, and the mat reaches working temperature rapidly after being switched on.\u003c\/p\u003e\u003ch3\u003eUniform Heat, No Hotspots\u003c\/h3\u003e\u003cp\u003eUnlike conventional heat mats that can develop localised hotspots, this mat distributes heat evenly across its surface. Uniform conductive heating is important for reptiles that press their ventral surface against the substrate to absorb warmth — it supports healthy metabolism, appetite, digestion, and general activity levels without exposing animals to dangerous concentrated heat zones.\u003c\/p\u003e\u003ch3\u003eThermostat Use and Temperature Gradients\u003c\/h3\u003e\u003cp\u003eAlthough the mat's self-regulating design provides a degree of built-in temperature control, pairing it with a thermostat is strongly recommended for accurate and reliable temperature management. When positioning the mat, always ensure a clear thermal gradient is maintained in the enclosure — animals must be able to move away from the heat source entirely. Cold spots are not optional; they are essential for effective thermoregulation.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePermanently adheres to the outside base of the terrarium for optimal heat transfer through the floor\u003c\/li\u003e\n\u003cli\u003eRubber spacers included to allow a small air gap where required\u003c\/li\u003e\n\u003cli\u003e8W output across a 20x15cm surface area\u003c\/li\u003e\n\u003cli\u003ePart of the PT2032 range, also available in 4W, 16W, and 24W sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCombining Heat Sources\u003c\/h3\u003e\u003cp\u003eFor species that benefit from both conductive and radiant heat, this mat works well alongside an overhead basking lamp. The combination of ground-level conductive warmth and overhead infrared-A radiant heat gives animals a broader thermoregulation toolkit, supporting activity, digestion, and general physiological condition.\u003c\/p\u003e\u003cp\u003eA well-chosen heat mat, correctly positioned and thermostat-controlled, forms a reliable foundation for any tropical or arid vivarium setup — giving keepers confidence that their animals have consistent, safe warmth around the clock.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54147632562513,"sku":"HHM108","price":22.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/HHM108_1.jpg?v=1782596677","url":"https:\/\/viperia.co.uk\/products\/et-ptc-self-regulating-heat-mat-8w-20x15cm-pt2032","provider":"Viperia UK","version":"1.0","type":"link"}
