Turtles are cold-blooded animals and they cannot internally regulate their body temperature in response to temperature changes in the environment.
Essentially, their body temperature will be the same as the air or water around them, so if it gets too cold, your pet turtle will become sluggish or worse get sick.
This is why turtle tank heaters are a crucial addition to your aquarium set up.
This small chart will help you choose the right turtle tank heater depending on your turtle tank:
- Up to 15 gallons = 50 watt
- Up to 30 gallons = 100 watt
- Up to 45 gallons = 150 watt
- Up to 65 gallons = 200 watt
- Up to 80 gallons = 300 watt
With a good heater, you can easily adjust the temperature to better suit your turtle’s needs, just make sure to choose one with compatible wattage for your tank.

- Very thin equipment
- Very well made all-in-one turtle tank kit
The market is full of a variety of heaters that range in price, specifications, and efficiency; it can all seem a little bit overwhelming especially if you are a first-time turtle parent.
However, do not worry; we got you covered with a breakdown of the ten best turtle heaters in the market today.
There are three kinds of heaters.
Submersible, substrate, and in-filter.
Each one of them has its gains and losses.
- Submersible Heater is a small, compact heater and as its name indicates, they work underwater. They are practical, easy to install, quick and efficient. They are usually inexpensive. They need to be far from the substrate to avoid accidents and malfunctions.
- Substrate Heater is the ideal heater for modest tanks. They work hidden under the substrate. Placed under the substrate, they stimulate the growth of water plants. Their main advantage is that they remain hidden, and they provide an effective heating method. However, they tend to be more expensive than the rest of the heaters.
- In-Filter Heater as its name indicates go inside the filter. More precisely inside the canister filter. The main advantage of this heater is that it is safe from being “attacked” by pets. This is useful mostly for aggressive fish owners. They are also an expensive option.

How to Heat a Turtle Tank
Generally, turtle owners who keep adults turtles do not actually have to heat their turtle tank but if you have a baby turtle you will need one.
This is because as you can image baby turtles are growing and you will want their metabolism to be active, to be able to digest their food quickly so they can consistently grow.
The adult turtles will no longer grow and they will not be using as much energy to go into the process of growing, so it’s not necessary to heat your adult turtle tank.
Adult turtles are very resilient and can withstand a wide range of temperatures.
Higher temperatures also help turtles fight off disease and illness more effectively.
As for the temperature in the turtle tank depending on the turtle you own, you can follow the list below:
- Hatchlings: 75-80* F
- Juveniles: 72+* F
- Adults: 68+* F ( or room temperature )
A precaution you can take is to have a heater guard so you won’t run into the situation of your turtle breaking the tank heater, just be sure it will fit the heat that you will buy.
Make sure you also have a thermometer so that you can test the temperature of the water to make sure it’s staying pretty consistent.
