The Different Types of Aquarium Heaters

There are different types of fish tank heaters. Each has its unique features and benefits. Here are the five main types of aquarium heaters:

Immersible Heater

An immersible heater is a type of heater that hangs on to the back of the aquarium but water covers the heating apparatus. It is the most common type of heater and also one of the cheapest.

Submersible Heater

You place the entire submersible heaters in an aquarium. When using these fish tank heaters, you must place them away from the substrate and other tank decorations. There should also be enough space for fish to swim around it.

In-line Heater

In-line aquarium heaters connect to the filtration system in your tank. You place these heaters between the tank and the filter. You usually use in-line heaters in larger aquariums.

In-sump Heater

Install in-sump heaters in your sump system. It’s ideal if you want to save space. They are the same as in-line heaters but take up less space.

Substrate Heater

Substrate heaters use heating coils placed on the bottom of the tank. You then use the substrate to cover the coils. They are not common and are the least useful type of aquarium heaters.
