How Do You Choose Your Heat Pad For Reptiles?

Choosing a heating pad for your reptile can be challenging, particularly, if you are unaware of the best in terms of cost and use on the market.

Before deciding on a reptile heat pad to go with, you need to consider the size, materials used to build it, the wattage, and the features of the device.

This video will help you properly set up an under-tank heat pad for your tank. 

1. Considering the Size of the Heat Pad

In choosing your terrarium heater, you need to take note of its size to see if it will fit the enclosure.

To be more accurate, measure the heater’s size (side or bottom) first before purchasing.

EXPERT TIP: Don’t purchase a terrarium heater the same size as the panels – keep it a few inches smaller to avoid excess heat.

2. Double-Checking the Materials Used to Build It

Check the materials of the terrarium heater and see if it’s durable enough for the purpose you’re aiming to use it for.

The best materials that can make the device up include carbon fiber, rubber, or any other material that can withstand and prolong the heat/temperature.

3. Ensuring That the Wattage is Just Right

The heat that the reptile heating pad emits would be something the wattage would be responsible for. Small tanks need about 4 to 8 watts, while big ones need around 20 to 24 watts.

Going over this can produce excess heat which will be bad for the health of your reptile friend.

4. Checking the Features of the Heat Pad

Lastly, take the time to look at the features of the heat pad. The best and most important features include being waterproof, temperature control, adhesive type, and so on.

When I choose mine, I always consider the size of the tank, what it needs, and what I think my pet reptile is looking for.  

I had many questions as a new reptile owner, so I am aware of what yours might be.  I’ll save you the headache by answering the most important ones.

Do Reptile Heating Pads Use a Lot of Electricity?

No, they do not. They use the same energy and electricity as a light bulb. Longer use saves energy costs. 

Where Do You Place a Heating Pad For Reptiles?

You can place most heat pads anywhere on the side of the bottom part of the terrarium, given that it’s equipped with one (1) adhesive side.
However, you should only place them at one (1) end or side of the terrarium so that you could establish a “cold spot” inside it.

How Hot Do Reptile Heat Pads Get?

Most reptile heating pads don’t get hotter than 120 °F (49 °C). The typical temperature for these reptile heating pads would be about 90 to 110 °F (32 to 43 °C).  
This will still depend on the wattage of the device. 

Can You Leave a Reptile Heat Mat On All the Time?

Yes, you can leave your reptile heat mat on for 24 hours a day, 7 days a week.
Even if you’re trying to save electricity, turning it off would not have a substantial effect.

How Long Does it Take a Heat Mat to Heat Up?

To be sure, wait a total of 24 hours before letting your reptile friends settle inside the terrarium with the heating pad.
Some users report a few minutes, a few hours, but those have not been proven yet. So at best, turn your heat pads on for at least 24 hours before placing your pet reptile in.

In Conclusion, 

Now, you know what the best heat pads for reptiles are on the market. Other than that, I was able to present to you a couple of tips on how to purchase the best heat pads.
