I think Finnex Titanium Hang-On Heater is the best water heater for turtles on the budget. If you want to learn details about the heater, read the rest of the article.

Keeping the right temperature is extremely important for turtle keeping. If the temperature isn’t right, then your turtle will face numerous health problems all the time. If the temperature is too low, then the turtle may get sick. On the other hand, if the temperature is too high, the turtle may not come out of the water to bask. Which will eventually make them sick.

Fortunately, controlling the temperature of a turtle tank is very easy. All you need to have is a decent heater and a reliable thermometer.

Why Turtle Tanks Need Heaters?

Turtles don’t have the ability to control their body temperature. They are ectothermic animals which basically means turtles are cold-blooded animals. The body temperature of the turtle is around same the temperature of the surrounding air and water. For performing various bodily operations such as respiration, metabolism, digestion etc. properly, the temperature range needs to be right.

That’s why it is extremely important to control the temperature of the turtle habitat and keep it constant throughout the year. By controlling the temperature of the habitat, we are actually regulating the body temperature of the turtle.

Best Thermometer For Turtle Tank: Zoo Med Digital Thermometer

Though most heaters come with a thermometer of their own, most of the time they don’t produce an accurate result. That’s why it is not smart to rely on the heater-thermometer alone. I always recommend getting a high-quality reliable dedicated thermometer for monitoring the temperature of your turtle tank.

You need at least two thermometers for your turtle tank: one for measuring the water temperature and the other for basking area temperature. When getting a thermometer for your turtle tank, avoid any type of poor quality glass thermometer as these get broken easily.

I think Zoo Med’s aquatic turtle digital thermometer is the best one in the market for using in a turtle tank. It is made from high-durable material and provides a very accurate result. Also, the digital display makes it easier to monitor the temperature.

Replacement battery is included with the thermometer. It is also completely submersible inside water. The thermometer measures temperature in Fahrenheit scale. You can easily place the thermometer anywhere inside the tank with the suction cup.

What Is The Right Water Temperature for your Turtle Tank?

The right water temperature for a turtle tank depends on the species of turtle, as different species have different temperature requirements. However, here is a general guideline for the appropriate water temperature for common pet turtle species:

1. Aquatic Turtles:

Red-Eared Sliders, Painted Turtles, and Map Turtles:

  • Hatchlings: 78°F to 80°F (25.5°C to 26.5°C)
  • Adults: 75°F to 78°F (24°C to 25.5°C

Softshell and Snapping Turtles:

  • Slightly warmer, around 78°F to 82°F (25.5°C to 27.5°C)

Do Turtles Need a Water Heater?

Turtles, depending on the species, may require a water heater to maintain an appropriate water temperature in their habitat. Here’s a general guideline:

Aquatic Turtles:

Aquatic turtles, such as Red-eared sliders and Painted turtles, typically require a water heater. They thrive in water temperatures between 75°F and 80°F (24°C and 27°C). A water heater helps in maintaining a stable water temperature, especially in colder climates or during the winter months.

Semi-Aquatic Turtles:

Semi-aquatic turtles, like Box turtles, may not require a water heater if they have a suitable basking area with appropriate heating. However, if they spend a significant amount of time in the water, maintaining the water temperature can be beneficial.

Terrestrial Turtles:

Terrestrial turtles, such as Tortoises, do not need a water heater as they do not live in water. However, they do need a suitable heat source to maintain their body temperature, such as a heat lamp.

Specific Requirements:

Different species of turtles have specific temperature requirements, and it is crucial to research the needs of the particular species you are caring for. Additionally, baby turtles may have different needs compared to adults.

Monitoring:

Regardless of the species, it is essential to monitor the water temperature regularly using a reliable aquarium thermometer to ensure it remains within the safe range for the turtle.

Health Implications:

Maintaining the correct water temperature is crucial for the turtle’s health. Inadequate temperatures can lead to a weakened immune system, making the turtle more susceptible to illnesses and infections.

How To Choose The Perfect Water Heater For Your Turtle Tank?

Using a heater is the easiest way to control the temperature of a turtle tank. There are many types of heaters available in the pet stores. However, you need to choose one depending on your tank type, size, and preference.

There are various factors to consider when you are buying a heater for turtle tank, such as:

Look for metal or thermal-resistant material

The first thing to look for in a heater is the material it is made of. The heater should be made of metal or thermal-resistant material. Glass heaters are not safe for turtle tank. It is because as turtles are bigger and more active than fishes, they may break the heater. Sometimes your turtle may also get electrocuted and severely injured.

Power Of the heater according to the tank size

The next thing you need to look for is the power of the heater. In easy words, the heater needs to be powerful enough so that it can warm up the entire turtle tank. We measure the power of an aquarium heater in watts.

Basically the more watt a heater has, the more powerful it is. Your heater needs to have sufficient wattage depending on the size of your turtle tank. Here are some general guidelines to determine the power of the heater according to the turtle tank size:

75 liters water (20 gallons tank): 75 watts

150 liters water (40 gallons tank): 150 watts

250 liters water (65 gallons tank): 250 watts

300 liters water (75 gallons tank): 300 watts

Think about the climate

Keep in mind that if the environment is too cold, then you might need a more powerful heater than a normal one. On the contrary, if the weather is warm, you might be able to get away with a less powerful heater. If for any reason you need to use more than one heaters in the tank, then add up their watts to measure the total wattage.

Careful placement of the heater

When you are using a submersible heater, make sure that it is placed in such a way that remains always inside the water. If there is no water around the heater, it may burn out in an instant and cause severe damage to the tank. Also when performing water changes, make sure that you’ve turned off the heater and pulled out the plug from the socket.

consider more than one heater for large tanks

If you have a considerably large tank, then it might be better to use more than one heater in the tank. It will ensure proper temperature control even if one of the heaters get broken. Moreover, with more than one heaters, you can get more wattage which is essential to control the temperature of a large tank.

functional temperature range: 73 to 85 degrees fahrenheit

You should get a heater that can operate in a temperature range between 73 to 85 degrees Fahrenheit. Adult turtles will do fine in cooler temperature than that. Baby or hatchling turtles require a bit warmer tank than the adult ones.

too much heat can be bad

Don’t go over the board with temperature. Too much temperature is bad for a turtle tank. It will encourage bacteria growth inside the tank which is unhealthy and risky for turtles. Moreover, it may discourage the turtles to bask which can cause severe health issues.

don’t look for cheap options

Heaters are something you don’t want to go cheap for. Cheap heaters are extremely risky and unreliable. I have seen hundreds of aquarium accidents due to a cheap heater. So, rather than looking for a cheap heater, look for a high-quality reliable one.

3 Types of Underwater Heaters

There are actually many types of underwater heaters that are designed for using in an aquarium. All of them do the same function, that is heating the water. However, there are certain advantages and disadvantages in each type of heaters. Let’s discuss briefly about them:

1. Submersible Aquarium Heaters:

Submersible aquarium heaters need to placed entirely in the water. You can either place them horizontally or vertically. They are usually rod-shaped with a knob to control the temperature range.  Submersible aquarium heaters are the most popular one because of their cheap price and availability. They are also very efficient and heat up the water very quickly.

Another good thing about using submersible heaters is, you can easily change the position of the heater. However, do not place them too near to the substrate. Also, place them in a place where the turtle can’t access it easily. Otherwise, your turtle may break down the heater and cause an accident. I love submersible heaters because they are very easy to use and provide much more accurate readings.

2. Aquarium Substrate Heater:

 It is another type of aquarium heater. Though they are not as popular as submersible heaters, many people use them because they don’t kill any space inside the tank. The way this heater works is, you need to place it under the substrate layer, whatever substrate you have such as sand, gravel or fluorite. As it is placed below the substrate, it is not visible.

Aquarium substrate heater works like a coil. It is more suitable for larger tanks rather than small tanks. They are much more expensive than submersible heaters and efficiency is less.

3. External In Filter Aquarium Heater:

Many people do not want to use a heater directly inside the tank. If you are one of them, an external in filter will be a good choice for you. These heaters are designed to work outside the main tank, typically in an external filter like a canister filter. By installing the heater inside the canister filter, you’ll get the desired water temperature without placing the heater inside the main tank. It also reduces the possibility of any accident.

If you want to use an external in filter heater, make sure that it has a water flow rate equal or more than the water flow rate of a canister filter. The fittings of the heater should also match with the filter hose.

External in filters will burn out if they are operated in a dry environment. So, after installing the heater, make sure the filter is filled with water and the pump is running. Only after then turn on the heater. I love the fact that you can use these heaters outside the main tank, which also reduces any chance of accident. However, they cost much more than submersible heaters which is a downside for many owners. If you are interested in this type of heaters, you should check out Hydor’s external in filter. They are the best in the market.

My Favorite Type of Aquarium Heater:

Among all of the types of aquarium heaters, I love the submersible heaters most. There are many reasons for preferring them over other types of heaters, some are:

  • They are very effective yet do not cost a fortune. Most people can get them easily from any pet store.
  • The installment is very easy and straightforward. You can also change the position and set it up in any way you want.
  • They provide much more accurate reading than any other types of aquarium heaters.
  • Submersible heaters are available in a large range of wattage power. So, you can easily get the one your tank requires.

How to Calculate the Required Power of Heater For Turtle Tank?

Calculating the required power of a heater for an aquarium involves considering the volume of water in the tank and the difference between the desired temperature and the room temperature. Here’s a step-by-step guide to help you calculate the required heater power:

Step 1: Determine Temperature Difference

  • Measure the ambient room temperature where the aquarium is located.
  • Determine the desired water temperature for your aquarium based on the species you are keeping.
  • Calculate the temperature difference (ΔT) between the desired water temperature and the room temperature.

ΔT = Desired Water Temperature – Room Temperature

Step 2: Calculate Aquarium Volume

  • Measure the dimensions of your aquarium or refer to the manufacturer’s specifications to find the volume.
  • If the volume is given in gallons, you can convert it to liters using the conversion factor: 1 gallon≈3.78541 liters

Step 3: Calculate Required Heater Power

  • A general rule of thumb is to use a heater with a power output of 3−5 watts per gallon of water for a temperature increase of 5−10 degrees Fahrenheit (3-5 degrees Celcius)

Use the following formula to calculate the required heater power (P) in watts:

Example Calculation:

  • Suppose you have a 20-gallon aquarium.
  • The room temperature is 68°F, and you want to maintain the water temperature at 78°F.
  • The temperature difference (ΔT) is 78°F−68°F=10°F

Aquarium Size vs Water Heater Power

Note

This table is based on a typical temperature difference of 10°F (5.5°C).

For larger aquariums, or as a safety measure, using two heaters of half the recommended wattage at opposite ends of the tank can help in maintaining a more uniform temperature and act as a backup in case one fails.
