At 30x20cm and 16W, it suits a wide range of mid-sized terrariums and can serve as a primary or secondary heat source depending on the species and setup.\u003c\/p\u003e\u003ch3\u003ePTC Carbon Fibre Technology\u003c\/h3\u003e\u003cp\u003eThis mat uses PTC (Positive Temperature Coefficient) carbon fibre heating elements, which self-regulate their output as temperature rises — reducing the risk of overheating without relying solely on external controls. The technology also delivers an electrothermal conversion efficiency exceeding 95%, meaning very little energy is wasted. An automatic fail-safe mechanism is built in as an additional safety measure.\u003c\/p\u003e\u003ch3\u003eUniform Heat, No Hotspots\u003c\/h3\u003e\u003cp\u003eUnlike basic wire-element mats, the carbon fibre construction spreads heat evenly across the entire surface. This eliminates concentrated hotspots that can cause burns or discomfort, and instead creates a consistent warm zone that reptiles, amphibians, and invertebrates can use to thermoregulate naturally — supporting metabolism, appetite, digestion, and activity levels.\u003c\/p\u003e\u003ch3\u003eThermal Gradient and Placement\u003c\/h3\u003e\u003cp\u003eThe mat adheres permanently to the underside of the terrarium, forming a solid bond that maximises heat transfer through the glass. It is designed to cover only part of the floor area, leaving a cool zone on the opposite side — this thermal gradient is essential and should never be overlooked. Rubber spacers are included to allow safe airflow where needed.\u003c\/p\u003e\u003ch3\u003eUse With a Thermostat\u003c\/h3\u003e\u003cp\u003eWhile the PTC element self-regulates to a maximum temperature, Viperia strongly recommends pairing this mat with a suitable thermostat for accurate temperature management. For a more complete heating strategy, combining under-floor conductive heat with a radiant infrared basking bulb allows animals to thermoregulate from both above and below, more closely replicating natural conditions.\u003c\/p\u003e\u003cp\u003eSupplied with rubber spacers.
