Types of Aquarium Heaters

heater1Heaters are necessary for tropical aquariums where the water temperature usually needs to be higher than the background temperature of the room the aquarium is placed. Many owners of temperate/cold-water fish also keep heating units in their fish tanks to make sure steady temperatures are kept through winter when temperatures in homes can decrease in the night when central heating is off. There are numerous different sorts of heaters around and different sizes offered for all kinds of aquariums. The standard principle is one watt per liter of water. For bigger tanks it can be better to have two smaller heaters at both sides of the tank to warrant even allocation of heat. Even if you heat your house, an aquarium heater is still expected. That’s because the aquarium water doesn’t just need to be warm, the temperature should also be as steady as possible.

Fish, particularly more fragile ones like marines and discus, are as stressed by varying temperatures as they are by water that’s too warm or cold. You don’t want the temperature to drop at night and then rise by day, for example. Tank heaters must for that reason use thermostats to keep the temperature steady. The thermostat may be a stand-alone unit that you connect to the heater or, usually it is built into the heater itself.

Filter aquarium heaters are placed inside the filter system and the water is heated up when it passed through the filter and the heater. They are the most aesthetic option since they’re fully external. And your filter defends it against any damage that might happen in the aquarium.

Submersible aquarium heaters are probably the most favored kinds of heaters because they are fairly cheap and straightforward to set up. These heaters are immersed in the water, so they can offer the right level of heating for the fish. The disadvantage is that it is not very easy to fix the heater when there is a problem. Also, because most of the heaters are made of glass, they can break when larger fish attack the heater.

BoxSubmersible tank heaters can be fully submerged in the water. Since these heaters are entirely submersible, they are usually more efficient than hanging type heaters. They can be positioned quite low in the water, they can be settled vertically, horizontally, or at a desired angle, still, they are likely to operate better when placed vertically or horizontally. Sometimes these heaters come with a built-in thermostat. This will make the thermostat easier to get a precise reading on the tank temperature and activate and deactivate the heater appropriately.
