Best Reptile Thermostat 2020

To ensure your reptilian friend’s good health and happiness, you’re going to have to understand they need specific care. This doesn’t mean that they will take more time to care for than other pets such as cats and dogs, but due to their inability to do some things by themselves, it unsurprisingly falls upon the owner to satisfy their needs.

The first of which is the shelter and environment for your cold-blooded companion. This is essential for their survival. To ensure that your reptile’s living conditions are ideal for them, you will need a good thermostat.

How to choose the Best Reptile Thermostat

When the temperature is too cold for your pet, its behavior will be significantly impacted; for instance, they become idler and might refrain from eating. Alternatively, if the conditions are too hot, then quite simply, your reptile will not survive. The importance of the right thermostat is emphasized because many reptiles cannot regulate their body temperature like humans meaning that the onus falls on the owner to provide the correct temperature.

To do this, you must install a heat source in your reptile’s shelter; however, it is seemingly impossible for one to monitor the temperature within the cage continually. That’s where a thermostat comes in handy. This device has a maximum temperature limit; once this is reached, the heating is turned off by the thermostat, and should the temperature begin to drop, then the thermostat switches the heat source back on. The thermostat essentially regulates your pet’s habitat’s temperature to ensure that you don’t have to.

It is no easy task finding a thermostat that is right for your pet’s needs. Therefore, to save you the worry, we have compiled the main criteria regarding choosing a thermostat in this article. We will also suggest some of the best thermostats on the market to make your job even more comfortable.

Things to Look For In the Best Reptiles Thermostat

When choosing the right thermostat for your pet, you must consider several features, all of which are listed below. It is imperative that you consider these to find a thermostat that suits you, your needs, and gets the job done.

Digital Thermostats: The alternative to analog are digital thermostats; these provide more precise readings than their analog counterparts; however, it is necessary to calibrate them before use, hence why you must check the readings and the preciseness of the set unit of temperature before use.

Ease of Operation: There are many reptile thermostats available on the market nowadays ranging from simple 3 button models to more sophisticated models that can be somewhat confusing and may take time to get used to. Ideally, you should purchase the more straightforward three button types. These are practical devices that enable you to regulate your reptile’s home’s temperature without the hassle and should be available on the best thermostat for reptiles.

Temperature Control Range: To have complete control over your pet’s home’s temperature, you should look for a thermostat that enables you to choose from several temperature ranges.

Programming: To alleviate the stress on your part, you should opt for a thermostat that can be programmed to switch on/off at certain temperatures and time intervals.

Guide For The Best Reptile Thermostat

Reptile thermostats are devices that enable you to regulate the temperature of your reptilian companion’s enclosure, given how the reptile itself is unable to do so due to it being coldblooded. To do this, you will have already installed a heat source that is switched on and off to keep your pet active and healthy.

If the reptile owner forgot to check the temperature of the reptile’s habitat, then the heat source could overheat the animal, causing it to die; similarly, drastic temperature changes in the enclosure need to be accounted for via adjusting the temperature settings of the heat source. Generally speaking, this would be a mammoth task for an owner, making the pet a considerable liability.

Luckily thermostats exist to do that for us. They switch off the heating when the temperature becomes too hot, thus providing ideal conditions for your pet. Given their reliability, owners needn’t stress about any temperature-related issues anymore.

Types of Thermostats for Reptiles

On/off thermostats

On/off thermostats are the most affordable variants of thermostats on the market. These switch all heat sources, including mats and cables, on and off at regular intervals via measuring the temperature through the probe, thus ensuring that the enclosure doesn’t become overheated.

However, such heating devices do not switch light bulbs in an enclosure on and off due to the danger and the possibility of exploding. This would inevitably do more harm than good for your pet.

Pulse Thermostats

Pulse thermostats are similar to on/off thermostats because they are unable to switch light sources on and off due to the flashes that this would cause, ultimately frightening the animal. Nevertheless, they are useful for regulating ceramic heat emitters. Pulse thermostats work by continuously measuring the temperature at the probe and consequently adapting the frequency of electrical impulses sent to the heat source based on this

Dimming Thermostats

Unlike the previous two variants, dimming thermostats can manage lights in an enclosure; however, this feature does come at an additional cost. Such thermostats are reliable at preserving temperatures and can be used in conjunction with most heat sources. They work by reducing the power sent to the heat source, consequently making the light source dim down (or up) to preserve the correct temperature.

Commonly Asked Question About Reptile Thermostats

What is the purpose of a reptile thermostat?

A reptile thermostat is a device that serves to measure and regulate the temperature of a reptile enclosure to prevent extremely warm/cold conditions.

What Is A Dimming Thermostat?

A dimming thermostat is a type of thermostat. Although it shares similarities with pulse thermostats, the main difference is that it can distribute less energy when necessary, rather than sending energy via repetitive pulses.

Should I use a heat mat with my thermostat?

It depends. Each thermostat comes with specifications stating its compatibility with other heating mats. While most are compatible with different heat mats, dimming thermostats are more suited to basking lights.

How do I adjust the nighttime drop in temperature?

While some reptiles species need the nighttime temperature to be a little lower, some thermostats can detect daylight and be set to adjust the nighttime temperature. Other thermostats have timers so that you can adjust the timer to a cooler nighttime temperature. This temperature adjustment can be somewhat daunting for new reptile owners, so it may be best if you start off with a more robust reptile species that doesn’t require a drop in nighttime temperature.

What Is A Proportional Thermostat?

Proportional thermostats alter the power output via increasing and decreasing to preserve the ideal temperature set on the thermostat.

What Is A Pulse Proportional Thermostat?

Pulse proportional thermostats are more advanced and ideal for regulating high power ceramic heaters and heat mats, in which case consistent heat is necessary instead of a standard on/off pattern.


Having read the main aspects of purchasing a thermostat, you can now make sound judgment when purchasing a thermostat for reptiles.
