The Best Turtle Tank Heaters (Review) in 2021

Last Updated April 26, 2021

There’s a level of security that comes with being warm, and most living organisms enjoy a little rise in temperature once in a while. Turtles need some heat to help with regulating their body temperature since they are cold-blooded animals. If you have a turtle for a pet, then you might probably be keeping it indoors a lot. This means that it cannot rely on heat from the sun to stay warm, and you might need to get an artificial source for it. Turtle heaters are one way to ensure that your turtle is kept warm enough to promote healthy growth. In this article, you’ll get all the relevant information on some of the best turtle tank heaters available.

Best Turtle Tank Heater Buying Guide & FAQ

Things to Consider When Choosing the Best Turtle Tank Heater

  • Design: This includes the shape, material, and how easy it is to manipulate and use the device. The material used in constructing the heater should be durable so that the device can serve its purpose efficiently. Some shapes allow for total submersion in water, while others are only attached to the rim or laid on the side of the tank. For submersible heaters, metal is recommended over glass because turtles have a hard shell that can break the glass. Whatever the case, it should be able to work without much trouble with handling. Heaters with suction cups or clamps are an excellent choice since they factor security for the animal.
  • Wattage: Generally, the higher the wattage, the more heat is going to be produced. Turtles need the temperature to be at a certain level so that they o not fall sick. The wattage on the heater will help determine if it is suitable for your turtle. For 20 gallons, you’ll need 75 watts and 150 watts for 40 gallons.
  • Safety: If you are working with electric heaters, then you should be aware of the risk of shocks. Electrical shock can be very harmful to your turtle that you’re trying to keep warm. Also, you should be able to regulate the temperature on the heater so that it doesn’t get too hot or too cold for the animal. In this case, heaters with thermostats will be the better choice to serve that purpose.

Different Types of Turtle Tank Heaters

Turtle heaters differ in design, purpose, and material, among other things. There are the flat surface bulbs that fit into a turtle tank lamp that functions outside the tank. There are also glass heaters that produce heat while submerged in the water. Another type is the mat form that you place outside the container. They also differ in wattage, and you can pick any water heater for turtle tank based on preference and needs.

Why Your Turtle Needs a Tank Heater

Turtles’ bodies take the temperature of their environment, leaving them unable to regulate their body temperature. They need external help to keep warm and prevent them from getting sick.

Best Turtle Tank Heater FAQ:

Q: What temperature should I keep my turtle tank?

A: For most adult turtles, 25.5°C or 78°F is the highest the temperature can go. Very high temperatures increase the rate of bacterial growth and discourage the turtle from basking, consequences that are a risk to the animal’s health.

Q: At what temperature do turtles hibernate?

A: When hibernating they can tolerate between 3.8°C to 10°C (39°F to 50°F).
