Aquarium Heaters

Fish keepers have to pay attention to much more than just the quality of water in their fish tanks. It is also important to know the ideal temperature for the fish as well as the right aquarium heater to use.

A large percentage of fish require warm water to have a problem-free existence, so unless you live in a year-long warm country, there is a chance that you’ll need an aquarium heater to keep your tank at a consistent temperature.


Aquarium Heater FAQs

  1. How does an aquarium heater work?

Since most of the fish in the market are tropical, aquarium heater has become important electric equipment for several home aquariums. Unlike other heaters on the shelves, the aquarium heater changes electricity to heat. The heater heats the water around the aquarium as water absorbs heat rapidly.

Once they are at the peak of the temperature setting, all aquarium heaters switch off by themselves. Meanwhile, there is no cause for alarm if the water overheat. The heater will start working if it discovers that the water drops below the required temperature settings.

2. How to set an aquarium heater?

Setting up an aquarium heater is a relatively easy process. Although it is easy to put this model into place, the installation processes can take a lot of time.

The three most important factors to consider while setting an aquarium heater includes:

  • How easy it is to adjust the thermostat control
  • How good you are at making adjustments with the thermostat control
  • How close to the correct temperature you set it for.

According to most fish keepers, it is advisable to place your fish tank heater close to the area where water enters and exits the aquarium filter.

The type of fish, as well as the temperature they require, helps to determine the correct temperature setting for your heater. After you have set your desired temperature, it is then just as simple as turning on the heater. Most of the aquarium heaters have a monitor light that shows when the heater is on!

3. Do fish tank heaters turn off automatically?

When the water temperature is reached the required set temperature set, the fish tank heater will automatically switch off. However, the aquarium heater will not overheat the water in a fish tank unless it is defective or has been set on the wrong temperature. When the desired temperature has been reached, every aquarium heater is made to turn off automatically. Therefore, you just need to crosscheck the aquarium heater settings before using it.

4. Do aquarium heaters use a lot of electricity?

The amount of electricity used by an aquarium heater depends on the fish tank. While the total electricity consumption for a small tank of about 10 gallons is about 150 kWh, a medium tank fish of about 30 gallons will use a range of between 150-200 kWh in a year. A large aquarium heater of about 55 gallons of water can use anything between 200 – 400 kWh annually. The water temperature is usually stable with excellent water flow.

Powerheads, protein skimmers, filters, air pumps, UV-filters, lights, water pumps, and among others are the major components of an aquarium heater that consume a lot of electricity. The lighting system in a fish tank also consumes a high amount of electricity.

It often takes about 45% of the total bill. Right behind aquarium lights for consumption is the heater. Which takes about 35% of the total cost. Then, the filter takes about 12% of the total bill while the air pump takes about 5% of the total bill.

5. Where should a heater be placed in an aquarium? Horizontal or Vertical?

A heater in an aquarium can be placed either horizontally or vertically (See best cheap option) depending on your choice. For instance, if you keep it horizontally and near the bottom of the tank, you will not need to worry about the water level in your aquarium. In the same vein, a heater placed horizontally near the bottom creates circulation by heating the water.

However, a lot of manufacturers recommend placing the heater vertically. It is believed that vertically placed heaters are more adjustable compared to their horizontal placed heaters.

6. Can the aquarium heater touch gravel?

The answer to this question depends on the kind of aquarium heater you are using. Generally, these heaters can touch gravel. However, while it is safe for some models, it is dangerous for the others. For glass-encased heaters, it is a wrong decision for the heater to touch the gravel.

This is because the glass-encased heater’s heating element is contained within the glass to insulate your water from the unit’s live circuit. Therefore, if the glass tube is cracked or broken, it will bring the heating element in contact with water and the glass of the fish tank. Likewise, the tank might not be safe for you as you can easily experience electric shock when you go to feed the fishes or touch the water.

7. Can fish get burned by a fish tank heater?

Even though fish burns hardly happen in a fish tank, there is a chance that it can occur from time to time.

Heater burns on fish occur in two stages which are the initial burn and the full extent burn. The initial burn is not as terrible as the full extent burn. Most of the time, it does not look too bad. What you only notice is opaque and a little white in the area of the burn. Within two to three days, this burn can escalate to the full extent burn.

At this stage, the fish tissue will look much worse. The burn will have already left a deep wound on the affected area and the damaged tissue will eventually flake away.
