Why Do Snakes Need Heating Pads?
Snakes are ectothermic, also called “cold-blooded.” This means that they can’t regulate their own body temperature. Their body temperature fluctuates according to their surroundings. To warm up, they must find a source of heat; to cool down, they must move to a cooler place.
In the wild, snakes naturally seek out heat sources in their environment. Corn snakes, for example, may find a sunny spot and bask on top of a rock or log until they’re warm enough. Ball pythons do not bask as they live in a tropical climate which is naturally warm enough for them year-round.
When keeping a snake in captivity, it’s essential to replicate the temperature of their wild habitat as closely as possible. This is especially important for tropical snakes as your home is far cooler than their natural environment.
Heat Mats vs. Heat Lamps
Heating pads, mats or under-tank heaters (UTHs), are rectangular mats that heat up. They sit underneath the tank and provide belly-heat for snakes.
Heat lamps are different. They hang above the vivarium and radiate heat downwards. They also emit light, brightening up your snake’s enclosure. Whether you should use a heat mat or a heat lamp will depend on:
- Whether your snake likes to bask. Basking snakes, such as corn snakes, prefer heat lamps. Pythons and boas prefer heating pads.
- The kind of enclosure. Heat mats work best with glass and plastic tanks. They struggle to penetrate wood, so heat lamps are usually better for wooden enclosures.
- How much humidity your snake requires. Heat lamps dry out the air inside the enclosure, so they work better for snakes with low humidity requirements, such as hognose snakes and corn snakes.
Heat mats are preferred because they provide no light, meaning that they can keep your snake warm 24 hours a day. If you use a heat lamp, you’ll need to use a different heat source during the night. Leaving a heat lamp on at night can disrupt your snake’s circadian rhythm (day-night cycle), potentially causing confusion and stress.
Best Heat Pads for Snake Tanks
There are many heating pads available, but they aren’t all of the same quality. You’ll often find, as with most products, that the more reputable brands tend to be made to a higher standard. Let’s explore further.
1) Zoo Med ReptiTherm Under Tank Heater
Zoo Med is a well-known brand for exotic pet products and foods. Among their offerings is the ReptiTherm Under Tank Heater, which is available on Amazon.
This heat mat is one of the most popular choices for beginners and experts alike. ReptiTherm UTHs are suitable for most reptiles.
- Choice of different sizes: mini, small, medium, and large.
- They are compatible with most thermostat brands and easy to set up.
- One side of the UTH is adhesive. It will stick to your snake’s tank, preventing it from becoming displaced.
- The product comes supplied with “bump-on feet” which attach to the underside of the tank. They raise the tank slightly, so that air can circulate around the heat mat, including underneath.
- ReptiTherm heaters don’t use much energy to operate.
- Affordable, especially for such a reputable brand.
- Only the smallest size, the mini, is listed as suitable for plastic enclosures. The manufacturer recommends that all other sizes are used with glass and wooden enclosures. This is because there is a risk of the heater melting the plastic.
- The adhesive is permanent. Once you’ve stuck the heating pad to the tank, you can’t remove it again. This can make cleaning the outside of the enclosure more difficult.
- ReptiTherm UTHs do not self-regulate, so a thermostat is necessary. Some people have found that, without a thermostat, the product can become hot enough to cause serious burns.
The disadvantages of this product can be overcome with DIY measures. For example, to remove the heat mat for cleaning, many snake owners recommend sticking a sheet of foil to the adhesive side and then taping the mat to the underside of the tank using electrical tape. That way, when you need to clean the tank, you can pull away the tape to remove the mat without it breaking.
Overall, the pros of the Zoo Med ReptiTherm UTH outweigh the cons. We’d rate it as the best heating pad currently available on Amazon, as long as you follow the instructions.
2) Zilla Reptile Terrarium Heat Mat
Zilla is another trusted brand when it comes to snake keeping. Zilla mainly specializes in tanks and tank accessories, such as hides, water bowls, and decorative pieces. They also offer heat lamps, thermometers and hygrometers, and heat mats.
Snake owners that do not choose the Zoo Med heat mat select the Zilla reptile terrarium heat mat. It is similar regarding both its pros and its cons, as well as its price point.
- The Zilla heat mat comes in a range of sizes, from mini to large.
- Zilla heat mats are thermostat compatible, allowing you to regulate heat in your vivarium.
- They are around the same price and quality as the Zoo Med mat.
- They do not use much energy to operate, although the larger the heating pad, the more energy it will use.
- These mats are designed to stick to the tank, and adhesive feet are provided for airflow.
- The adhesive which sticks the Zilla heat mat to the tank is temperamental. It sticks well at first, but can come away.
- The Zilla mat works well for glass and thick, robust plastic tubs, such as Rubbermaid or Really Useful Box brand. However, it may be a melting hazard for thinner or cheaper plastic.
- This heat mat does not self-regulate. You’ll need to purchase a thermostat to prevent the heating pad from getting too hot.
- If your room is particularly cold, this heat mat does not produce enough power to adequately heat the vivarium.
The Zilla heat mat has many of the same benefits as the Zoo Med heating pad, with the slight inconvenience that the adhesive is as strong. However, you can get around this by using some electrical or HVAC tape to secure the mat back onto the tank.
As long as you purchase a thermostat to use with it, we would recommend the Zilla reptile terrarium heat mat and consider it a solid choice. You can order one on Amazon.com.
3) iPower Under Tank Heat Pad and Digital Thermostat Combo Set
iPower specializes in products designed for growing plants, such as lights and greenhouse ventilation. However, they have released a UTH specifically for snake enclosures. They are a major brand in the horticultural world.
The main benefit of this product is that it comes with a heat pad and a temperature regulator.
- Because the heat mat comes with a thermostat, there’s no need to purchase any additional equipment. You can plug the mat into the thermostat and set the temperature right away.
- The thermostat is digital, meaning it’s very precise, and will keep temperatures in your enclosure within a set range.
- The heat pad is adhesive and sticks to the bottom of the tank.
- Due to the inclusion of the thermostat, it’s suitable for use with strong plastic containers, as long as you do not set the temperature too high.
- The heat pad is made to be water-resistant, although we would still not recommend using it inside the vivarium.
- It heats up to the desired temperature quickly.
- The quality of this product can be a bit hit-and-miss. Some reviewers have complained of receiving a faulty thermostat, or that the heat pad does not warm up to an adequate temperature.
- There is only one size of heat pad available – 4” by 7” (4W). This is fine if you have a smaller enclosure, but isn’t suitable for large vivariums.
- The package states that the product is supplied with under-tank feet. However, some reviewers have claimed that they did not receive them, so you may have to get them separately.
- The heat mat isn’t suitable for thinner or more flimsy plastic tubs which may have a lower melting point.
Despite the above cons, the majority of reviews for the iPower heat mat and thermostat combo on Amazon are positive. It is a cheaper option than the Zilla or Zoo Med offering when you consider that the thermostat is included in the price.
Overall, this product is slightly lower in quality than other top brands. We would certainly recommend it for smaller enclosures.
4) Fluker’s Heat Mat for Reptiles and Small Animals
Fluker’s is a reasonably well-known brand in the reptile world. They mainly specialize in reptile food, such as turtle food and bearded dragon food. However, they also sell snake tank accessories, such as lights, water bowls, and heat mats.
The Fluker’s heat mat for reptiles and small animals has positive reviews. Unlike most other top heat mats, Fluker’s hat mats are not adhesive, meaning that they are reusable.
- There are 4 sizes available: mini, small, medium and large. Whatever the size of your snake’s vivarium, there will be an option to suit you.
- Because the heat mat is not self-adhesive, it is reusable time and time again. Perfect if you need to clean the outside of the tank, or switch your snake to a larger enclosure.
- It uses little energy, yet still reaches up to 100 degrees Fahrenheit.
- The mat is very durable, made of high-quality materials, and is thermostat compatible.
- The price is reasonable and in line with other leading brands.
- Because the mat isn’t self-adhesive, you’ll need to purchase some tape separately to stick it to the tank. Use a heat-resistant kind, such as electrical tape or aluminum (HVAC) tape.
- The heat mat does not come with under-tank “feet,” so you’ll need to buy these separately to ensure proper airflow under the enclosure.
- There is no way of setting the temperature, so you will need to get a thermostat separately.
- Some have remarked that their heating pads haven’t reached high enough temperatures.
The Fluker’s heat mat, which is available on Amazon, is an excellent choice for anyone who isn’t a fan of self-adhesive mats that permanently stick to the tank. This is a good thing for owners of hatchling or juvenile snakes as they’ll need to be moved to larger enclosures as they grow.
5) Sequoia Reptile Under Tank Heating Pad with Temperature Control
The Sequoia reptile comes with a built-in analog temperature control dial, which is wired into the product itself, rather than being a separate thermostat.
Sequoia is not a well-known brand, but its heat pad is very affordable. The reviews for this product are generally quite good.
- The heat pad has an analog temperature control dial built-in. There is no need to buy an additional thermostat to regulate the temperature.
- The control switch can regulate the temperature between 32 and 95 degrees Fahrenheit, meaning it’s suitable for almost all kinds of snake.
- The heating pad is waterproof and condensation proof.
- There are two different sizes available: 11” x 11” and 5.5” x 5.9”.
- The heating pad does not consume much power, even when adjusted to the highest setting.
- Because the thermostat is analog, not digital, it is not as precise. There are no numbers on the dial to indicate the temperature that you would like to set it to. For this reason, you’ll have to buy a separate thermometer for your vivarium and adjust the dial as necessary.
- The heat mat is self-adhesive, but there are only 2 thin strips of adhesive on the product, rather than the entirety of one side. For this reason, you may need to use tape to secure it further.
- The Sequoia heat mat only reaches a maximum temperature of 95 degrees Fahrenheit (though inside the tank, the temperature may be much lower). This means that for snakes requiring higher temperatures, this heat mat may not be adequate.
The Sequoia heat mat (on Amazon.com) is not as high quality as some of the others that we’ve reviewed. However, most reviewers are happy with it given the price.
We would recommend using this mat with a proper digital thermostat to be on the safe side. Be sure to closely monitor the temperatures inside your vivarium while you’re using this mat.
Are Heating Pads for Snakes Safe?
Heating pads for snake tanks are safe if you follow the safety guidelines:
- Follow the instructions when setting up your heat mat.
- Never place the heat mat directly inside your snake’s enclosure. There’s a risk of burns if your snake touches the heat mat directly, and you don’t want your snake to become tangled up in the wires. Spilled water or urine could also damage the heat mat.
- Always use a thermostat to check for signs of overheating.
Thermostats keep the temperature inside the vivarium within 2 or 3 degrees of the optimum level. They continuously monitor the temperature, and automatically switch off the heat mat once it reaches the correct level. When the temperature drops below the optimum level, the thermostat switches the heat mat back on again.
According to Veterinary Clinics Exotic Animal Practice, environmental temperatures that are too high or low can result in a weakened immune system. This can predispose the animal to various illnesses, such as respiratory infections.
How to Set Up a Heating Pad for a Snake
A snake heat mat setup is straightforward. Here are some guidelines:
- Plug the heat mat into the thermostat. Follow the instructions to set the thermostat to the optimum “warm end” temperature for your snake. For example, if you’ve got a ball python, you might set it to around 95 degrees Fahrenheit. Remember that the temperature above the substrate will be slightly cooler than the mat itself.
- Set your heating pad underneath one end of your snake’s tank.
- Sandwich the thermostat’s temperature probe in between the heat mat and the bottom of the enclosure. You can use electrical tape to secure it there. Do not place it inside the enclosure as your snake shouldn’t be able to touch the wires.
- Closely monitor your heat mat and thermostat for the first 5-6 hours to make sure that everything is working correctly. Use an infrared thermometer (temperature gun) to check the temperature inside the enclosure just above the substrate. Adjust the thermostat if you find that it gets too hot or cold.
You shouldn’t have to do anything more. Your thermostat will do all the work monitoring and adjusting the temperature. Just make sure you check periodically to make sure that it’s all still working optimally.
