T-Rex Cobra Heat Mats

As a primary heat source, this heat mat produces the uniform, evenly distributed warmth reptiles and amphibians require by mimicking the gentle heat of the sun. The mat remains at a steady 100 degrees Fahrenheit, emanating warmth to animals sitting on top of the substrate or cage furnishings. T-Rex Cobra Heat Mats are the most widely used vivarium heaters in the world. For glass or acrylic aquariums.

How Heat Mats Work
T-Rex Cobra Heat Mats are made from incredibly reliable and accurate copper elements. They produce ultra-long wavelength infrared heat. This wavelength is invisible to the human eye and tends to heat furnishings in the cage rather than the air. This action of heating is very similar to the sun and it has the ability to heat anything that it strikes, but the air temperature remains low. Reptiles absorb this heat in a manner very similar to basking in a natural environment. Heat mats do get warm but provide a very gentle warmth, which the animal can sit under or on top of. Used under normal conditions, the mats cannot burn the animal.

If you are keeping animals that require high temperatures, you may need additional heating, such as a basking spot or other source of localized heat. T-Rex Cobra Heat Mats are an excellent primary heat source for most applications requiring nighttime heating. They emit no visible light and are the most widely used heater for this purpose.

T-Rex Cobra Heat Mats are perfect for use with all reptile and amphibian species. For heating most snake species and invertebrates, T-Rex Cobra Heat Mats are excellent as the sole heat source.

NOTE: For use inside or outside of tank, positioned on floor or walls.

Installation Guide
Choose a heat mat size so that it covers between one third to one half of the vivarium floor or back wall. Make sure your heat mat is larger than your pet, so that it can warm all of his body mass at the same time. It may be more convenient to attach the heat mat to one end wall, in which case, the size of the mat can be selected to cover from one half to most of this end wall, dependent upon the heating level required. The unheated portion of the vivarium will then provide the cooler area that is so important to most reptiles and amphibians.

With glass or plastic vivariums, the T-Rex Cobra Heat Mat may be attached to either the outside or the inside, as those materials readily allow heat to pass through them. Double-sided sticky pads or strong adhesive tape can be used to affix the heat mat, positioned only along the clear plastic edges, so that no heat output is blocked. A sheet of styrofoam of at least one-half inch thickness can be used on the back of the heat mat to reflect all produced heat back into the cage. This styrofoam should be cut to cover the entire base of the vivarium, not to the size of the heat mat, if the heat mat is to be positioned underneath a glass or plastic vivarium. This will help to ensure that the base is not stressed, which may cause it to crack. It will be convenient to cut out a small recess area from the styrofoam to accommodate the thickness of the electrical cord's terminal block. This prevents local pressure on the terminal block stressing the base of the vivarium. The thickness of the layer of substrate used inside these types of vivariums, particularly if of an insulating nature, must be kept to a minimum to prevent thermal blocking.

Vivariums constructed of wood or melamine-coated chipboard are much better insulators, and with these, the heat mat can only be positioned inside. If placed outside these types of vivariums, little or no heat will penetrate inside and there is the real risk of thermally blocking the heat mat.

Warning: Thermal blocking is caused when the heat from the heat mat cannot escape because there is too much insulation material on either side of it. In these situations, heat output continues to be generated until damaging or fire risk temperatures are achieved.

These heat mats can be positioned on cage walls or floors. If positioned on the floor, they should not be covered with more than a sprinkling of insulating types of substrates, such as vermiculite, bark chips, or wood shavings. Substrate coverings using non-insulating materials such as sand or gravel should be limited to a depth over the heat mat of not more than one-half inch. Too thick a substrate depth will reflect the heat output from the heat mat in the wrong direction. This could, at the very least, cause damage to the vivarium floor or crack it if constructed of glass. If a thick layer of substrate is required, then wall mounting of the heat mat is recommended.

Thick-bodied reptiles sitting for long periods on floor mounted heat mats can also cause thermal blocking. Wall mounting is the safest heat mat location option for all larger species of reptiles.

Wall mounting is also essential if there is any risk of the inhabitant damaging the heat mat by either digging activity or wetting it with waste fluids.

Precautions
It is essential to safeguard against the heat mat becoming wet with waste fluids or any other liquid. If immersed in liquid, the heat mat is likely to fail and may overheat. Normal routine cleaning with a damp cloth is perfectly safe, though you should disconnect the heat mat from the electrical supply source first.

Any heating device for reptiles or amphibians must be fully tested following installation, and preferably 48 hours, prior to the introduction of the animal.
