Benefits of Aquarium Heaters
The most common benefit is keeping the water at a certain temperature. You might have filled the aquarium with water at room temperature, but that is not a guarantee that it will remain that way. You need a heater to keep it within the best range for your pets in the aquarium.
Depending on the type of fish you have in the tank, the need of a heater may not have been important before. Some types of fish will need a higher temperature to survive other than the room temperature. This means having a heater to raise that temperature.
The heater is also important for maintaining the water temperature. This is important so that the water temperature does not create a stressful environment for the fish.
It is just like for humans; you do not want to be in an environment when the temperature will change suddenly or frequently.

Nowadays, aquarium heaters are designed to be easy for users to install. There are a few variations depending on your particular aquarium heater but all heaters can generally be installed with the following steps.
- Examine the heater before installation. Make sure the casing is intact, no signs of damage on the heating element and no exposed wires.
- Find a suitable location in your aquarium that you want to install the heater. Make sure the glass surface in that area is clean.
- Use the suction cups provided by the manufacturer to attach the submersible heater to the desired location. Adjust the heater if possible. Ensure no plants or aquarium decorations don’t come in direct contact with the heater.
- Allow at least 15 to 30 minutes for the heater to rest within the water before turning it on. This allows the casing to adjust to the surrounding water temperature so there is no cracking from the sudden change in temperature.
- Place an external thermometer in your aquarium opposite from your heater (if your heater does not come with a thermometer to read the water temperature). Read the initial reading of your aquarium water.
- Turn your heater on and adjust to the desired temperature.
- Allow the heater to operate for about 24 hours before checking the thermometer for aquarium temperature. Check your heater every four to six hours and adjust the setting up and down until the desired temperature is reached.
- Finally, add your fish to your aquarium. Because of the high level of fluctuation on the few days, the heater is set up, having your fish in the tank before adjusting the temperature may irritate the fish greatly.
Where to Place Aquarium Heater?
This is often a simple but overlooked question when it comes to aquarium heaters. It is advisable that you keep the heater new the water flow. It could be the outlet or inlet from the filter or even the stream of a power head.
This is because having the water flowing directly past the aquarium heater makes it easy for the heat to disperse easily throughout the aquarium.
How Much Electricity does an Aquarium Heater Use?
You do not only need to plug the heater into an electric source but you also need to leave it turned on almost all the time. That undoubtedly will increase your electricity bill. But, by how much?
Heating an aquarium can be expensive depending on your tank size. The larger tanks, the more heat it is required and the more expensive it will be. In addition, a tropical fish environment usually requires a higher water temperature, which means more electricity spent on turning up the temperature on the heater.
Generally, a 30-gallon tank heated at 72F or 22 degree C will consume approximately 110 kWh. You can calculate this rate according to your tank size to guess how much electricity your tank will use to be heated.
The same tank, if it is heated at 82F or 28 degree C will consume about 440 kWh per year, which is 4 times as much.
In general, there is no way to give you an exact number of how much your electricity bill your aquarium tank will cost. But with the size of your tank and the temperature set, you can do some guesswork based on information provided above.
How Many Watts Does my Aquarium Heater Need?
Here is a guideline you can use to determine what heater you need. Remember, it can change depending on the performance of your particular heater.
|Tank size||Watts needed to increase 5F||Watts needed to increase 10F||Watts needed to increase 15F|
From the list above, it is possible for you now to pick the best aquarium heater with ease. Many people who have used them always ended up with top quality products that deliver on performance always.
You can be the next one to keep your fish and at the right temperature needed for survival. Go ahead and pick the one you feel is the best.
