There are a lot of different types and sizes of aquarium heaters on the market. So, what watt heater do you need for a 20 gallon aquarium? The answer depends on a few factors, such as the ambient temperature in your home, whether you have multiple fish or just one, and how big your fish is.
Generally speaking, you’ll need a 50-watt heater for a 20 gallon aquarium if the ambient temperature in your home is around 70 degrees Fahrenheit. If you live in an area with warmer temperatures, or if you have multiple fish in your aquarium, you may need a 100-watt heater.

Aquarium Heater Size Chart in Litres
If you have an aquarium, chances are you need a heater to keep the water at a consistent temperature. But what size heater do you need?
The size of your aquarium heater should be based on the volume of water in your tank.
A good rule of thumb is to use a heater that will provide 3-5 watts per gallon (w/g) of water. So, for example, if you have a 50 gallon aquarium, you would need a 150-250 watt heater. Of course, there are other factors to consider when choosing an aquarium heater, such as the type of fish you keep and the ambient temperature of your home or office.
But using the 3-5 w/g rule is a good place to start. Once you have an idea of what size heater you need, check out our handy Aquarium Heater Size Chart below. Just find your tank’s capacity (in gallons) on the left and then match it up with the appropriate wattage on the right.

When it comes to setting up an aquarium, one of the most important aspects is choosing the right size heater. Not all heaters are created equal and there are a few things you need to take into account before making your purchase.
The first thing you need to do is measure the tank.
This will give you a good starting point for figuring out how much power you’ll need in a heater. The general rule of thumb is that you’ll need about 2-5 watts per gallon of water. So, if you have a 10 gallon tank, you’ll need a 20-50 watt heater.
Once you have your wattage figured out, the next step is to choose a heater with the correct controls. Most heaters will have an adjustable thermostat so that you can set it to the perfect temperature for your fish. It’s important to find one that also has an automatic shut off feature so that it doesn’t overheat and damage your fish or equipment.
Finally, make sure to read the reviews before purchasing any aquarium equipment. There’s nothing worse than buying something only to find out later that it doesn’t work as advertised! By taking your time and doing some research upfront, you can be sure that you’re getting the best possible product for your money.
How Many Watts Per Gallon Heater
If you’re wondering how many watts per gallon heater you need, there’s a simple formula to follow. First, determine the desired water temperature increase in degrees Fahrenheit. Then, multiply that number by 4.25.
The resulting number is the minimum wattage required for your aquarium heater. For example, say you have a 10-gallon aquarium and you want to raise the water temperature by 10°F. 10 x 4.25 = 42.5 watts, so you’ll need an aquarium heater with at least 42 watts of power.
It’s important to select an aquarium heater with enough wattage to do the job, but not too much wattage or else you’ll overheat the water. Use this formula to find the perfect size aquarium heater for your needs!
Aquarium Heater Size Guide
Heating an aquarium is essential to the health of your fish. A properly heated aquarium will maintain a consistent water temperature, which is vital for the metabolism and respiration of your fish. In addition, a heater can help prevent drastic temperature changes that can stress or even kill your fish.
So what size heater do you need for your aquarium? The answer to this question depends on a few factors, including: -The size of your aquarium
-The type of fish you keep -The water temperature you desire As a general rule of thumb, you should use a heater that will raise the temperature of your aquarium by 10 degrees Fahrenheit.
For example, if your room temperature is 70 degrees Fahrenheit and you would like to maintain a water temperature of 80 degrees Fahrenheit in your aquarium, you would need a heater that produces 8 watts per gallon. To calculate the wattage required for your specific situation, use this formula: gallons x 10 = watts needed. For example: A 30 gallon tank x 10 = 300 watts needed to heat the tank by ten degrees
Keep in mind that some types of fish require higher or lower temperatures than others. For instance, tropical fish generally prefer warmer waters while goldfish and other coldwater species do better in cooler temperatures. Consult with your local pet store or veterinarian to determine the ideal water temperature for the type of fish you keep.
They can also help you select an appropriate sized heater for your aquarium.

What is the Best Heater for 20 Gallon Fish Tank?
There are many types of heaters that can be used for a 20 gallon fish tank. The best heater for your specific tank will depend on the type of fish you have, the water temperature you need to maintain, and your budget.
Some common types of heaters include:
Submersible Heaters: These heaters are placed directly in the water and are one of the most popular choices for aquariums. They are relatively inexpensive and easy to use, but can be difficult to keep clean. Additionally, if not properly maintained, submersible heaters can break and leak electricity into the water, which can be dangerous for both you and your fish.
Glass Aquarium Heaters: These heaters sit outside of the aquarium on a stand or shelf and use a glass tube to transfer heat into the water. Glass aquarium heaters are more expensive than submersible heaters, but they offer a few advantages; they tend to last longer, they don’t require as much maintenance, and they are less likely to break or leak electricity into the water. However, glass aquarium heaters can be more difficult to install than submersible heaters.
Undergravel Heaters: These heaters sit underneath the gravel at the bottom of the aquarium and use warm water rising from below to create circulation in the tank. Undergravel heating systems are relatively inexpensive and easy to install, but they require regular maintenance to prevent problems such as clogs or leaks. Additionally, undergravel heating systems may not be suitable for all types of fish tanks.

How Many Watts Should My Aquarium Heater Be?
If you are looking to purchase an aquarium heater, it is important to choose one that is the correct size for your tank. Most importantly, you want to make sure that your heater can handle the number of watts that your tank requires. To figure out how many watts your aquarium heater should be, you need to first determine the size of your tank.
The next step is to calculate the wattage per gallon by using the following formula: Watts per Gallon = (Tank Size in Gallons * 8.34) / Heater Efficiency For example, let’s say you have a 50 gallon tank and you want to use a 100 watt aquarium heater.
Using the formula above, we would calculate that as follows: Watts per Gallon = (50 * 8.34) / 100 = 417 Watts per Gallon
This means that your 50 gallon tank would require a 417 watt aquarium heater in order to maintain proper temperatures.
If you’re wondering what wattage heater you should get for your 20 gallon aquarium, here’s a quick guide. A 20 gallon aquarium requires a heater with a minimum of 50 watts. However, it’s always best to err on the side of caution and get a slightly larger heater just in case.
For example, a 75 watt heater would be ideal for a 20 gallon aquarium.
