The #1 Best Reptile Thermostat in 2022

A thermostat is the single most critical piece of equipment for anyone who keeps reptiles. Why? Because reptiles thrive within a specific temperature range, a thermostat helps you manage your terrarium temperature. A thermostat helps you manage your terrarium temperature.

As a reptile’s body temperature decreases, they move less, their digestion slows down, and their immune system stops functioning correctly. Too much exposure to cold makes it harder for reptiles to fight off secondary infections. Exposure to severe and prolonged cold can be fatal.

Reptiles need heat, but too much heat is as harmful as too much cold. You may know that the most common cause of premature fatality in reptiles is overheating. 

Our 2022 reviews are updated to look at the best reptile thermostats available on the market, so you have what you need to keep your reptiles in that perfect temperature range to keep them active and healthy.

Choosing the Best: What to Look For

Your reptiles cannot maintain a comfortable temperature on their own. Depending on where you live, they need heat or cooling in their terrarium to stay healthy and happy. A thermostat enables you to create an environment where they can thrive.

When you are shopping for a thermostat, it’s important to know what you need. Some questions to ask include:

  • Do you need more than one probe or is one enough? 
  • Do you need a display that hangs easily, or do you have a place for it to rest? 
  • Are you away from home a lot – would a remote app be helpful?
  • Do you need a waterproof probe due to the high humidity in your terrarium?

The answers to these questions will direct you to the best reptile thermostat for you.

The Different Types of Reptile Thermostats: Pros and Cons Compared

Reptile thermostats are separate from heating and cooling units. They provide a digital display and temperature control for the heating and cooling mechanisms you already use in your terrarium. For that reason, they are pretty simple, and there aren’t many distinguishing factors between the different types. However, they do vary in manufacturing quality, single versus dual probe, and waterproof or not.

Here are some pros and cons of each type.

Manufacturing Quality

Some units come with guarantees. Some manufacturers state they use more durable plastic or have tested the units for durability and reliability. Since it’s a fairly simple mechanism, less robust manufacturing quality isn’t a deal killer, but you will have to replace the unit more often. 

Single Versus Dual Probe

A single probe will measure and regulate the temperature of the spot where you place it. Dual probes can help you regulate two different temperatures independently. If you are planning on purchasing multiple units because you have several terrariums, dual probes might simplify the process and save you some money.


Most terrarium thermostats are not waterproof, which means they can rust or stop working if exposed to too much water. A waterproof probe is most often used for a fish tank rather than a terrarium. Still, if you have a moist environment or a very humid terrarium, a waterproof probe might work better or for a longer period.

Verified Review: User Experience

Users of the Zoo Med ReptiTemp RT-600 Digital Thermostat Controller say that it’s easy to use and accurate. It measures the heat in a specific area very precisely, so reviewers who use a heating mat say you want to keep the thermostat on the mat for the most accurate reading. If you mount it on the wall of the terrarium it will measure the temperature of the air and the wall. Several users reported they were so satisfied with the initial experience they bought more for other terrariums. The main complaint was that setting the temperatures is somewhat awkward, but fortunately, you don’t need to set them very often.
