Submersible heater is one that works within aquarium water and can be placed anywhere in the tank with suction cups. It is the most popular and affordable type of aquarium heaters in the market today. Submersible heaters usually feature an adjustment knob on their top for setting your desired temperature. After setting your submersible heater to an optimal temperature for your fish, just position it in a suitable place in your aquarium and plug it in.
Another type is Hang-On controller with heating tube. It includes two component: a digital controller and a heating tube. The controller works outside the aquarium and controls the work of the heating tube. The heating tube is submerged in aquarium water to heat it to a temperature controlled by the controller. Aquarium heater controllers with heating tube are usually designed with high wattages for large aquariums. They are ideal to keep an optimal temperature for large to extra-large fish tanks.
