The aquarium heater is an essential device for maintaining the optimum temperature in the water body at any time of the year. When buying the device, it is advisable to focus on the ability to adjust the temperature and power, which depends on the features of the aquarium.
For an even heating of water, there is an optimal ratio of volume and power, which corresponds to 10 watts per 4.5 liters of water, if the room is not very cold. For the same reason, it is recommended to purchase several weak products instead of one.
Main types of aquarium heaters
- Submersible heater. Most of the designs are made in the form of a glass tube, inside of which is a spiral and a temperature regulator. The aquarium heater with the thermostat after immersion in water works automatically, without requiring the participation of a person. Quality products are absolutely hermetic, they have a special case, which has a special strength and shock resistance.
- Thermal cable. This product is placed under a layer of soil. During operation, the water heats up and rises, evenly distributed along the aquarium.
- Flow heaters. The system that circulates the water supplies it to the heater, where it is heated by a powerful thermoelement. The product consumes a lot of electricity, so it is not considered economical.
In order for the aquarium heater to work in the right mode, you should use it as indicated in the instructions. For modern designs it is enough to set the necessary temperature and install the device in the right place. Electronic products are considered to be more accurate, because they have less error than mechanical ones. To control the device, aquarists recommend to buy an additional thermometer . Especially it is necessary in hot weather, when there is a risk of overheating of water.
