If you’re keeping a pet reptile at home, you must know there are certain elements they need in their enclosures. One of those is a heat mat. Along with incorporating a ceramic or basking bulb into your reptile’s habitat, you can set your scaly friend up with both a secondary heat source. The overhead bulb mimics the heat that emanates from the sun, which is where they would normally obtain their warmth. It’s natural for reptiles to seek out a heat source that exists above them. Heating pads are a little different because they deliver heat to your reptile from below. A basking bulb or ceramic bulb along with a heat mat work in tandem. The heat mat warms the substrate at the bottom of the tank while the overhead bulb crates that warm air pressure reptiles are attracted to.

A heat mat only works for a certain area of your reptile’s tank. Reptiles need a spectrum of temperatures with an area to cool off and an area to get warm. A heat mat helps to isolate one area and make it a warming or basking area for your reptile. Allowing your reptile to choose whether to warm up or cool down is extremely important as they exercise autonomy in natural environments. The best types of heat mats already come equipped with built-in thermometers and temperature controls. Heat mats should never cover the entirety of the floor of your tank. This would create way too much heat that would make your reptile extremely uncomfortable.

To find the best heat mat for your needs, you need to consider the size and features of different heat mats. Below, we highlight the top-rated options you have so you know where to direct your attention when deciding on a final option. We give you all of the details you need about each product to help you understand whether it’s a good choice for your reptile. We also help you by providing some tips on how to choose the right heat mat and break down how to properly use a heat mat in you are reptiles habitat.

Best Overall: iPower 8 by 12-inch Under Tank Heat Mat Reptile Heating pad with Digital Temperature Control

The best overall heat mat for your reptile is the iPower under tank heat mat. This heat mat measures 8” x 12” but there are some smaller options and one larger option as well.

It’s equipped with a new PTC heating material which increases insulation overall. Heat transfer is easy across the mat, and you can reach the desired temperature in just a few short minutes. It has 3M adhesive paper which provides a strong grip on the contact area. Once you place it down, it stays put.

This heat mat is ideal for use with reptiles, other small animals, amphibians, and even plant terrariums. The digital thermostat helps regulate the temperature and you can select between Celsius or Fahrenheit. It has an easy plug-in operation with LED indicator lights and a three-prong grounded plug. This design is also great for saving energy. It consumes significantly less power than other heat mat products.

On average, customers rate this heat pad 4.4 out of five stars. One customer says that it works as advertised so long as you use it properly. She found the thermostat easy to implement and she uses this heat pad along with a bulb for the day. She did make a mistake with the temperature probe when she used it the first couple of times because she placed it about 2 inches above the base and it was giving her measurements that were somewhere between 5°F to 10°F lower than they actually were. This caused her to think that it wasn’t heating properly for her corn snake but once she moved the temperature probe to the bottom of the tank, she received more accurate readings.

How to Choose the Right Heat Mat for Your Reptile

Your reptile needs a solid heat source to survive and thrive. However, not every heat mat is designed in the same way. They vary in wattage, output, quality, and extra features. Nevertheless, there are a few things that you should consider before purchasing a heat mat for your reptile. For one, it should be specifically made for reptiles. You should not be using any other type of heat mat in your reptile tank. Your heat mat should also have safety features like automatic shut off after a certain temperature is reached. The wattage should always be somewhere between 4 and 24 watts as well.

The reason you shouldn’t use any other type of heat mat unless it’s specifically designed for reptiles is because these products are usually preconfigured to stay within a certain heat range. For example, you could potentially find a cheaper product that’s meant for industrial work. Yes, you’ll save up front, but those heat pads are not designed for reptiles and quickly overheat, making your reptile uncomfortable, or worse.

You can always purchase a thermostat separately from your heat mat or you can purchase an option that has this built-in feature already. A thermostat works as a safety feature to automatically shut off the heat pad if it goes past a certain temperature setting. Any time you’re using a heat source, even when it’s high-quality, you should always remain vigilant. A thermostat helps keep you abreast of your reptile’s environment so you can make real-time adjustments as needed.

When we talk about the wattage range, it’s because the wattage of your heat mat is ultimately what determines just how hot the mat will get. Generally, larger heat mats get hotter than some of the smaller options though that is not always the case. Using improper wattage for your reptile’s needs can lead to having the wrong temperature settings for your reptile. If the temperatures don’t get high enough, your reptile may become slow and sluggish. Additionally, this may cause issues with your reptile’s digestive system. On the other hand, if it gets too hot, your reptile can suffer from respiratory infections, or all the symptoms related to dehydration.

To give you an idea of how to shop, consider that a 20-gallon tank would do well with 8 watts. If you have a much larger tank that’s about 50 or 60 gallons, then you’ll need something like 24 watts. A smaller 10-gallon tank can operate well with 4 watts. Knowing the wattage can help narrow down your choices. If you have a 10-gallon tank, go for 4 watts and a heat mat that measures about 4” x 5.” If you are in the 20-gallon range, you’ll need a heat mat that is somewhere closer to 6” x 8.” For a super large 50 or 60-gallon tank, purchase a heat mat that measures 8” x 18.” If it’s too small, your reptile won’t have enough of a temperature gradient for comfort. If it’s too big, it creates the same issue but with not enough of a cool space for your reptile to enjoy.

How to Properly Use a Heat Mat for Your Reptile

Each of these top-rated heat mats is designed for ease of use and durability. They shouldn’t require too much figuring out upon delivery. To create the best experience for your reptile, you should position your new heat mat on the tank before you add any other products like substrate. Remember, you have to create a temperature gradient inside the tank so usually, the best place for your heat mat is beneath the overhead heat source. This way, your reptile can warm up and absorb the UV rays it needs to remain healthy. When you have the basking bulb directly above the heat mat, you create an ideal environment where you are killing two birds with one stone.

Once you figured out the best configuration for your heat mat alongside your basking bulb, go ahead and remove the protective cover of the adhesive on your heat mat. Go ahead and add the heat mat to your desired location and make sure that it doesn’t cover more than half of the tanks floor. Then, you can turn it right side up and begin adding your substrate. Remember not to use too much substrate because then the heat will not be able to emanate as effectively upward for your reptile. If you purchased a heat mat that comes with the temperature probe, go ahead and insert it down into the substrate just above where you’ve placed the heat mat. Remember that if the probe is too far from the heat mat, the temperature reading won’t be accurate, which can cause the thermostat to communicate to the heat mat that it needs to create more heat. This may not actually be the case and could become dangerous.

You may want to consider adding an extra, independent thermometer, so you have a different temperature reading to confirm the temperature reading of the built-in thermometer for your heat mat. After installing a heat mat for the first time, you’ll want to keep an eye on it. Keep checking back regularly to make sure that the temperature is staying within the appropriate range. Once you have confirmed that everything is working properly, you can move forward with setting up the rest of the habitat and introducing your reptile to its new and improved enclosure.
