Important factors to consider while buying the best aquarium heaters

How to choose the right aquarium heater:

You decide the vibe of the type of aquarium heater you choose and how many to use however there are many types and to pick the right one, it all depends:

  • Hang-on-tank: Hang-on heaters basically mount onto the tank rear with suction cups and/or a hook or other fastening device over the edge of the tank itself. They are partially submerged and have a tendency to be less effective than other types of heaters, but they can offer sufficient heating in smaller tanks. When it is used in big-sized tanks, it’s best to have more than 1 hang-on heater on opposite sides of the aquarium, for the best experience.
  • Submersible: Submersible heaters are fully submerged in the tank water and horizontally or vertically mount to the back of the tank. Typically, they are technically mounted near the substrate. Submersibles often provide more consistent and effective heating than hang-on heaters, especially with larger tanks than other types.
  • Heating cable: A heating cable generally is put under the gravel or substrate and connected to a control unit nearby. It may be useful for freshwater planted aquariums to remove dead spots around. Nevertheless, in the sense that you have to dig up the substrate if there calls for a replacement or repair, this type of heater wouldn’t be the best option for saltwater reef systems in your aquarium.

Best Aquarium Heaters FAQs:

What are some useful tips for use?

In larger tanks, or in circumstances where the room temperature is comparatively below the wanted water temperature, two heaters may be useful. Heaters should be installed at opposite ends of the aquarium to ensure even heating for the best heating provided. 

It is recommended to use multiple units with hang-on and submersible heaters at the same time. This gives us more even heat distribution and places less strain on the heaters as well. Additionally, if one of the heaters breaks down, the temperature may not all of a sudden drop too dangerously until you can get a new unit as a replacement. It’s also advised to buy an extra heater to keep on hand as a backup for the worst-case scenario.

The heater tube length is extremely essential when the heat rises. Mechanically speaking, the heater tube needs to match the height of your aquarium as much.

Check for heat sources and fluctuations in room temperature where the aquarium is placed carefully. Your tank can be located under an air vent or adjacent to non-concomitant heat sources making the temperature rise and fall alternatively.

Some aquarium heaters contain specific number settings for the thermostat control then you can set it to the go-to temperature. Other heaters have specific controls that fluctuate from low to high, without specific temperatures shown. The former ones are far easier for users but don’t forget to check to make sure that the heater setting is actually keeping the aquarium at the correct temperature as per speculation.

Where Should I Put My Aquarium Heater?

There are loads of kinds of aquarium heaters, but we’re going to talk about the most typical type – submersible heaters that operate fully underwater. The water current assists to spread the warmth from the heater over the rest of the tank, so ideally the heater should be put right adjacent to the filter output or pump for maximum flow as well. The installation of a thermometer in a corner opposite the heater probably makes sure the heat is reaching the other side of the tank properly.

Some heaters necessarily have to be positioned vertically all day long, while others can be placed horizontally. If possible, it is highly recommended that you should mount the heater at a 45-degree angle to get the best heat distribution. You can also conceal the heater by placing plants and decoration in front of it or hiding it in the sump in the case that you have one to use.

Why do we need a heater for the aquarium?

Because most aquarium fish on offer are tropical, an aquarium heater becomes necessary for many home aquariums. Unless you reside in a tropical area, an aquarium heater for your fish is something must-have.
