Choosing the Best Reptile Thermostat

Reptiles are cold-blooded creatures that can’t stay warm on their own. A secure and comfortable enclosure is crucial for your reptile’s well-being, long life, and breeding. While heat lamps provide enough heat, it can be hard to screen and maintain an enclosure climate without a thermostat.

So, if you want the best reptile thermostat, this is the article for you. You need to know plenty of things, like what heating system you own, and lots of products to pick accordingly. To find out what reptile thermostat suits your tank best, keep reading.

Buying Guide

Reptile thermostats aren’t easy to pick. There are multiple varieties, and each one has a unique feature. You’ll have to figure out what thermostat you require according to your heat source and other criteria.

Type of Thermostat

There are mainly two kinds of thermostats: On/Off and dimmer thermostats. While each thermostat performs the same task, they execute it differently.

On/off temp regulators are most commonly used and for valid reasons. They’re efficient, cost-friendly, easy to control, and offer more flexibility. These devices maintain heat by shutting the lamps off or on according to the enclosure’s current temperature.

On the other hand, dimmer thermostats regulate lamps’ brightness and power output to provide a consistent climate. These devices only function with heat lamps since they require the lights to work. While you can find a small number of dimmer thermostats out there, we don’t recommend installing them.

Instead, use an on/off regulator. In theory, they both have the same function: set your terrarium at a specific temperature. The only difference is that an on/off device does it in half the cost.

Temperature Probe

A probe is an instrument used to measure the temperature via sensors. They’re thin, needle-shaped objects that connect to the thermostat using a wire. When companies mention a product’s temp probe length, they refer to the wire’s size attached to the probe.

The probe length is vital for several reasons. First of all, it provides you with some wiggle room and more workarounds when it comes to the installation of your thermostat. So, you can position your reptile thermostat further away from its enclosure if the probe connects via a longer wire.

It also makes it convenient to change the thermostat’s position in the enclosure if need be. Heat mats and lamps are useful, but they can be quite space-consuming in small sections. So, having a more extended probe makes adding it to the tank more convenient, specifically in navigating the wire around more objects.


The wattage of any electrical device is crucial. While many users look at power usage to figure out how expensive a thermostat will be, there’s still more to know.

Wattage helps people establish a thermostat’s maximum load. If a thermostat has a max wattage of 1,000, you’ll have to ensure your heat sources work at or below that threshold. Thankfully, most reptile thermal regulators have a wattage of 1,000-1,100, which matches other heating devices.

Temperature Range

Here is another essential criterion to observe. The thermal range includes all the temperature values that a reptile thermostat can monitor. Specific devices, for example, can display temperatures from 40° to 220°.

Most reptilian species thrive in a climate ranging from 70 to 85° and bask in temps up to 100°. So, when choosing a reptile thermostat, aim for one built to handle this temperature range.


Reptile thermostats aren’t expensive commodities. However, the price of each device does vary greatly. It depends on the quality and the number of features a thermostat possesses. For example, a thermostat with both cooling and heating properties will be costlier than one with only heating.

The Zacro digital thermostat comes with different features. It includes an LCD that stays illuminated even at night, making the readings visible, so you’re comforted knowing your reptile is safe. It can show readings in both temperature scales, and you can choose which one to display.

Typical reptile thermostats have an error margin of around one or two degrees. The Zacro is unique in that regard since it’s one of the most precise thermal devices on the market. This accuracy is remarkable most other several thermostats are more expensive while having larger error margins.

The thermostat is precise, but the temp probe length isn’t something to boast. The average probe length of a reptile thermostat is around six feet, but the Zacro only provides four cable feet. While not a big dealbreaker for most reptile owners, most owners would prefer a more extended probe at half the price.

Still, the Zacro thermostat makes up for its literal shortcoming with its high accuracy. Probes are rarely perfect, even in more extended models, but having 0.1 accuracies is a huge plus. If you own an exotic reptilian animal that needs specific temps for breeding or basking, it’s best to have the most accurate device out there.


What is the ideal temperature for reptiles?

Reptile thermostats should typically range from 70 to 85 degrees. Some tank systems also set specific regions for cooling or basking. Reptiles like to bask in high temps early in the morning to increase their body temperature quickly.

Not all reptiles like basking, but if your reptilian friend prefers to bask, you’ll want to have a separate section. Basking spaces should regulate a temp from 90 to 100 degrees. So, reptile thermostats are needed to control the ideal temperature.

Generally, reptile thermostats have a temperature range of 40°-120°. For most reptile owners, that’s all they require. Even so, if you own an exotic pet that needs higher temps, it’s best to buy a reptile thermostat boasting a more extensive temp range.

An example of this is the Bayite thermostat, which can maintain higher temp sets in more exotic reptile tank systems.

How do reptile thermostats work?

Reptile thermostats work by offering a ‘sliding’ quantity of electric supply to their heat source that allows the heat source’s light collection to either illuminate or dim enough to regulate the temperature.

What is the best reptile thermostat?

The best reptile thermostat is one that can regulate the temperature properly to maintain the ideal temp in your reptile tank. You can check our reviews to help pick the most effective thermostat among the eight options above to determine which one works best for you.

How do a rheostat and a thermostat differ?

A rheostat doesn’t come with a probe to measure temperatures, while thermostats do. The probes are essential since thermostats monitor temp readings without trusting on room temp. Also, in most scenarios, thermostats provide more precise readings.

Can I connect more than one heating source to a thermostat?

Depending on the device you opt for, yes! Specific devices can work with both heating and cooling devices. What establishes this feature is their number of inputs. If a thermostat comes with two or more three-pronged sockets, you can connect multiple heating sources.

Do I need a reptile thermostat?

Technically, you could run a heating source without a reptile thermostat, but it’s best if you didn’t. Reptiles have specific temperature requirements, including basking spaces. So, it’s best to use a thermostat to maintain these particular environments. If you don’t own one, you can use a regular thermometer till you find one.


Looking for a reptile thermostat is not always easy, but it doesn’t have to be hard either. It’s essential to buy a thermostat according to your needs without worrying about other things. If you buy the incorrect reptile thermostat, you can end up with broken heating sources and a sick reptile.

Thankfully, picking the best reptile thermostat is easy when you have the best options to research. So, take your time to consider the requirements of your pet before buying any one product.
