Best Turtle Tank Heater: The Buying Guide

Here are a few factors that you must consider to manually find the perfect heater for yourself. Or else, you would have to leave it up to luck.

1. The Type of Heater You Want

There are quite a number of types of heaters available (Just three). Each of them gives you an advantage on a specific factor and a disadvantage on others. Let’s get to know them.

Submersible Tank Heaters: It is not rocket science but submarine science that submersible heaters are kept underwater. This is apparently the most common type of heater available. Because, it’s obvious- something that will heat the water must be in full touch with the water, right?

These are cheap, easy to set, and very available. You can mount it both vertically and horizontally. The unit looks very much like a stick.

Apparently, the reason you may not want it is quite visible in the tank and you may not want it to ruin the beauty of the tank. Other than that, as it is fully exposed, if your turtle for some reason like to poke it- it may get damaged.

Substrate Heater: Most people love to hide the hard-working heavy-duty units from plain sight. It is as if acknowledging the things that bring balance is a sin. So, you do not want people to know that there is a heater in the turtle tank? Then, you can hide it.

Apparently, substrate heaters are the heaters that you place under the substrate of your turtle tank. It may be gravel, sand, etc. Whatever it is- the heater will do just fine. It is best if the layer of the substrate is thick as it will hide the heater well. Apart from that, these are less popular but more expensive than submersible tank heaters.

External Heaters: Is your turtle tank really small and just the addition of a heater will eat up a lot of space? Then, you need an external heater. A filter is a must in a turtle tank- whether it takes space or not. So, most external heaters just reside in the filter.

This is an example of hitting two birds with one stone. So, when the filter filters water, the heater heats the water it comes in contact with. It’s an efficient process. Furthermore, the heater stays protected from the ambush of aggressive turtles. This type of heater is expensive but it lasts a while and does a good job.

2. The Material Building The Heater

No matter how good the heater normally is or how expensive- it will be useless if broken. Turtles are strong creatures with a hard shell- if your heater is made of glass- a turtle can easily break it if it wants. On the other hand, the glass may harm the turtle as well.

Therefore, make sure that the heater you are buying is made of metal. Furthermore, it should be made of heat-resistant material. It should not give off chemicals or radiation because of what it itself produces. Because that would be like a suicide mission.

3. The Size of The Heater

Talking about the physical attribute here. Heaters can arrive in various shapes and sizes. You have the flexibility to choose one that fits your needs. If you want a small one for your small tank then you will find one.

On the other hand, if space is not an issue, you can just focus on the other aspects of the heater

4. The Wattage of The Heater

You do not really need the heater to heat the water to a boiling temperature- that’s dangerous. In fact, all you need is to find a temperature that is neither too high nor too low for the turtle. The turtle should just be alright staying in the water.

It should neither feel too lazy in cold water nor too uncomfortable in hot water. This is something that the power of the heater will determine Higher the wattage, the hotter it can get. This is actually quite risky as when the heater malfunctions, it can suddenly heat up the water to the highest temperature and kill the turtle.

So, it is best to stick with lower watt- like 150-watt heaters or even less.

5. The Features and Range of Temperature

If it is winter in a cold country, then the requirement for the heater will be much higher. Again, if it is winter in a hot country, you do not really have a big range to worry about. So, you should check the range of temperature the heater is capable of heating the water too.

Apart from that, look for safety features and also the ability to control the temperature. You should be able to set a particular temperature for the water. Other than that, the heater may have an alarm system in it that goes off if the temperature crosses a certain limit.

These features may cost more but they may be the line between your turtle’s life and death.

6. Dual Heaters

It’s not always easy to understand if the heater is working properly. In fact, you will not always be around to check. Anything may happen in this short time.

This is why consider dual heaters. For example, you may actually need 300 watts of power. Instead of buying a heater of 300-watt power, why don’t you buy a dual heater that has two heaters operating separately at 150 watts?

It is highly unlikely that two heaters will malfunction at the same time. So, if one malfunctions, the other still takes care of the temperature. Again, if the other overheats, it won’t reach a destructive temperature. Because the highest it can go is 150, not 300 watts.

Best Turtle Tank Heater: The Benefits of Buying

Why should you invest in a separate turtle tank heater when you can just leave them under the sun? Here’s why.

Provides The Necessary Amount of Heat

Leaving the water to heat up following the natural process can take time. And, when it does heat up, you have no control over the temperature of the water- that is why it is essential that you install a controllable heater in a turtle tank.

Provides Regardless of The Season

You do not get the same temperature of water in both summers, winter, or even two consecutive days. A heater can keep the temperature of the water at constant number. Your turtle won’t have to waste its energy adjusting to the temperature of the water every now and then.

The Perfect Temperature

Not all turtles require the same temperature to be perfectly healthy. So, your turtle’s needs may be different. There are so many types and varieties of heaters available that you can find one suitable for your turtle along with its temperature range easily.

Frequently Asked Questions (FAQ)

What Are The Standard Powers For The Various Sizes Of Tanks?


You may find yourself overwhelmed when choosing the right power for your tank. Apparently, it is an easy decision. Start with 20-gallon tanks requiring 75 watts of power. Similarly, a 40-gallon tank will require 150 watts of power (double the previous). A 65-gallon tank would require 250 and a 75-gallon one would require 300 and likewise.

Best Turtle Tank Heater

Final Notes

You cannot be negligent about something that controls the health condition of your little turtle friend. Since you have taken up the responsibility to take care of the little living creature- you might as well take good care of it. Heat is a very important factor in a turtle’s life and growth.

Therefore, make sure you put in all your efforts, knowledge, and observation power when choosing the best turtle tank heater.
