The Best Turtle Tank Heater | Submersible & Inline Heaters

Live in a cooler climate and need a turtle tank heater to keep your pet warm?


Different turtles have different water temperature requirements. The most popular pet turtle is probably the Red Eared Slider, and it requires a water temperature of 75-86°F.


Depending on where you live, and the variety of turtle you have, you’ll either need to warm your tank up, or make sure your tank is kept in a cooler part of the house to keep the temperature down.

The Best Tank Heaters For Turtles


The cheapest, easiest to use, and most common style of turtle tank heater is known as a submersible tank heater. You’ll recognize them, they can also be used in 55 gallon fish tanks.


The most important thing when buying a submersible heater for a turtle tank, is that you not buy one made of glass. Turtles can easily break glass submersible heaters with their shells. This could easily result in the death of your turtle through electrocution.


Another style is inline tank heaters. This is an external heater that draws water out from the tank to heat it. These are generally more complicated and expensive.


We’ll be looking at 2 submersibles and one inline heater. I’ll only be recommending heaters that have been tried and tested with turtles already.


Aqueon Pro Adjustable Heater


This 150 watt Aqueon heater is the perfect turtle tank heater, and my top pick. It is for tanks up to 55 gallons. If you have a smaller tank you are able to choose smaller sized and lower watt heaters from the same listing.


The biggest benefit of this heater is that is not made of glass! Your turtle’s shell is not going to bump it, break it, and electrocute itself with a heater like this. It is “shatterproof and nearly indestructible” as the listing states. Essential for use as a turtle heater!


Features of this heater include:

  • strong, durable, non-corrosive shell
  • even heat transfer
  • electronic thermostats for accurate temperatures
  • LED light power indicator (red when heating, green when temp. reached)
  • can be used in fresh or saltwater
  • can be placed horizontally, vertically, or diagonally
  • SUPER affordable


This heater has been rated and reviewed almost 1500 times on Amazon, and has an excellent reputation. The company selling it, Aqueon, are also know for their great service, support and products.

Finnex Titanium Tube Aquarium Heater For Turtles


Finnex Hang-On Electronic Controller Aquarium Heater, Titanium Tube


Next up is the Finnex aquarium heater, made from titanium, and sure to stand up to a turtles hard shell. However, it doesn’t look quite as nice as the previous tank heater!


This heater also comes in a range of different watts. The one I’ve linked to is best for up to 55 gallons, but you can shift between different sizes within the listing.


Features of this heater include:

  • hard titanium shell
  • heats to +/- 1-2 degrees of set temperature
  • corrosion resistant
  • good for either salt or fresh water tanks
  • fast heating
  • LED indicator light
  • install vertically, horizontally, or diagonally


This heater is also well worth your consideration if you would prefer the metal casing to plastic.

Hydor In-Line External Heater

As the name states, the Hydor tank heater is an external water heater. Now this type of heater is much more complicated than a submersible, so it’s best you watch the following video to get a good idea as to how it works.



The water is drawn through the machine and pumped back in at your set temperature. There is quite the set up with tubing, etc. but it is a high quality heater that your turtle will not be able to mess around with. Read the FAQs for this machine here.
