The Best Reptile Heater Your Pet Will LOVE

When you install it according to the manufacturer’s instructions, a heating pad is one of the safest heating options for your pet reptile’s home.

Since the heat pad only produces heat in a specific area, it also helps to create a temperature gradient.

You want a temperature gradient for your pet, since it allows them to choose the level of warmth that suits them best at that moment.

Choosing the right reptile heating mat may seem daunting, but it’s straightforward. Join us as we learn more about the best reptile heating pad options.

Curious or in a hurry? 
Buyer’s Tip: This reptile tank heating pads are large enough to heat up 50-60 gallon terrariums. We also highly recommend this heating pad for snakes and other reptiles since it is available in multiple sizes.

In Short

  • A heat mat operates as an external heat source, warming a specific part of your pet’s terrarium.
  • It’s safe to use a seedling heat mat for your pet, as long as it has a thermostat or doesn’t reach extreme temperatures.
  • The best heating pads for reptiles have a built-in thermometer and temperature controller.
  • Never attach a heat pad to the whole bottom of your pet’s terrarium.

How to Use a Reptile Heating Pad

The best reptile heating pads are simple pieces of equipment that don’t take a lot of thought.

For best results, set up the heating pad BEFORE filling the enclosure with substrate and adding your pet.

You need to find the place where your heat pad will be most effective in creating a “hotspot” for your pet.

Since most reptiles require the combination of a heat source and UV bulb, the best reptile heat pad location is below the bulb.

This configuration allows the reptile to absorb heat while absorbing ultraviolet rays.

Other setups may lead to your pet using either the heat mat or the bulb instead of both.

Let’s run through how to use heating mats step-by-step.

  1. When you’ve determined where to place the heating pad, remove the cover from the adhesive side of the pad.
  2. Stick the heat mat to the bottom of the tank—it should cover no more than one-half of the tank’s underside.
  3. Turn the tank right-side up, and add substrate.

    Top Tip: Since a reptile heat pad is external, you should use no more than an inch of substrate. Using more than that may compromise the efficiency of the heating pad.

  4. If the product you chose came with a temperature probe, insert that into the substrate above the heat pad.

    Expert Tip: When you use a thermostat with your reptile heating pad, you need to ensure that the temperature probe is above the heating pad.

  5. If the probe is too far from the heating pad, the thermostat will get the signal that the heat mat is cold and keep trying to push up the temperature. This type of error can have a lethal result.
  6. If your reptile heat mat came with a thermostat, or you bought one, set it to the appropriate temperature for your pet reptile.
  7. Use an independent thermometer, which you know is accurate, to measure the temperature above the heat mat.
  8. Check the thermometer every 30 minutes for three hours. If the temperature stays within the desired range, you can go ahead and finish setting up the habitat.

Can You Use a Seedling Heat Mat for Reptiles?

This question is one of the most common queries from hobbyists looking for their first heating mat.

The simple answer is yes, as long as it comes with a thermostat or doesn’t get too hot.

It should also be small enough to fit under a selected part of your pet’s enclosure. You don’t want a heating mat that will heat the entire bottom of the habitat.

We feel so confident about the safety of using seedling heat mats for heating your pet’s habitat that we’ll even make a recommendation.

VIVOSUN Seedling Heat Mat and Digital Thermostat

The VIVOSUN Seedling Heat Mat and Digital Thermostat is a regulatable system that provides all the heating your cold-blooded pet might need.

This system is large, at 10 x 20.75 inches, so it’s best to use it for larger enclosures.

This VIVOSUN Seedling Heat Mat and Digital Thermostat can maintain temperatures between 40°F and 108°F and comes with a simple yet efficient controller with three buttons.

You’ll use two of the buttons to set the controller to the appropriate temperature, and the third changes the display temperature between °F and °C.

Since the design of this VIVOSUN Seedling Heat Mat and Digital Thermostat focuses on seedlings rather than reptiles, it doesn’t come with an adhesive backing.

It is, however, entirely waterproof.

Are Reptile Heating Pads Safe?

If you follow the manufacturers’ directions, reptile heating pads are one of the safest and most efficient heating options.

This safety is the result of how you set up a reptile heating pad. Rather than placing the device in the tank with the animal, it sticks onto the bottom of the tank.

Since the heat source is external, there’s NO risk of the reptile accidentally burning by touching it.

When installed correctly, the heating pad also helps create a temperature gradient rather than heating the entire habitat.

Most basic reptile heating pads have a built-in cutoff switch that prevents the device from overheating the tank.

Not all heating pads for reptiles come with this function, and they may malfunction.

It’s always wise to use a thermostat with your device, which will keep the heater in the optimal temperature range.

As long as you DON’T install your heating pad inside your pet’s habitat or place it in contact with anything flammable, this is a convenient and safe heat source.

Top Tip: Manufacturers specifically design some reptile heating mats for use inside enclosures. Read the packaging carefully to determine whether your heat pad is an under-tank heater.

How Important Is It to Have a Separate Thermometer?

Whether you buy a complex system with a thermostat, or a simple plug-and-play heating mat, monitoring the temperature and humidity is essential.

We have an entire article about the best thermometers and hygrometers for your reptile enclosures. We suggest having a look at that before you buy a device for your pet’s tank.

Most of the more complex heating systems come with a relatively accurate thermometer probe, which allows the thermostat to determine whether the heat pad needs to get hotter or cool down.

The downside of relying solely on the thermostat’s temperature probe is that if the thermostat malfunctions, the thermometer may glitch as well.

Built-in thermostat probes generally don’t take humidity readings, so you won’t know if you’re drying out your reptile while trying to keep it warm.

We recommend buying a reliable and reputable reptile thermometer for your enclosure. It will help you keep track of the ambient temperature.

Your enclosure should also have at least one hygrometer (humidity meter) to help you manage the tank’s humidity.

You can also buy a device that acts as both a thermometer and hygrometer. These are ideal for keeping track of the general conditions in your terrarium.

In most cases, it’s a good idea to have a general thermometer to keep track of the ambient temperature and a dedicated thermometer located above the heating mat.

By keeping an eye on the dedicated thermometer, you’ll know exactly if and when your heat mat malfunctions and can handle it accordingly.

How Does the Substrate Affect My Under-Tank Heater?

Though you might not think so, the type of substrate that you use can have a significant impact on the temperature your heater reaches.

Before we discuss the substrates themselves, it’s worth noting that glass isn’t the best conductor of heat.

Glass is the product of superheated silica sand, so it keeps a few of its conductive properties, but it also has some minor insulating qualities in its finished form.

The result of this combination is that glass is more of a semi-conductor than anything else, and you’ll lose a fair bit of heat while trying to push the heat through the glass into the substrate itself.

Let’s get back to the substrates. Once the heat makes its way through the glass, it still needs to warm the substrate so your pet can benefit from it.

Different substrates have different reactions to heat. For example:

  • Vermiculite and perlite both come from superheated processes. They’re insulators, but they’ll maintain heat for a while once they’re warm.
  • Wood chips are an insulation material. Once they’re warm, they’ll maintain the temperature for a while, but they also offer plenty of initial resistance to heating up.
  • Recycled paper, newspaper, and cardboard are all insulators. They resist heat, and they won’t maintain warmth for any length of time once the heating mat deactivates.
  • Coco peat, peat, and sphagnum are all insulators. They react in much the same way as wood chips. They’re also involved in constant slow decomposition, so they may produce some minor heat.
  • Sand is a conductor; it will absorb and redistribute heat. This property makes it a suitable substrate above heat mats but can also make it hard to gauge which temperature will reach your pet.

In short, the type of substrate you use has a significant impact on the temperature the tank ultimately reaches.

Using a combination of elements can either improve or worsen your substrate’s ability to get warm.

First, find the substrate that works for your pet, then add more heat or drop the heat to compensate for the substrate’s unique qualities.
