Any heater would be a completely useless item without such an important element, as an electric tan. At first sight, it would seem, a minor detail determines the entire activity of the water heater. In this article we will consider the features of these devices.
Electric heaters
Electric heaters are an indispensable part for heating water, oils, gas. The part is removable, which guarantees uninterrupted operation of the device in case of failure of this element.
General characteristics
Electric heater is a specific design, which is widely used today. It is able to convert electrical energy into heat. This is very convenient both from a practical point of view, and in terms of savings.
This category includes standard shades for the water heater, which can be found in ordinary apartments, and great, more powerful machines, which are used mainly in industry. In the first case it is enough 220 V, and in another - 380 St..
In any case, it does not matter, what power to consider the device, it will consist of heating elements, which in the device are located in a certain environment. The case is always made by special technology, usually, carbon steel is used for this purpose, which is not subject to corrosion.
Electric heater is able to heat such media:
- water;
- gas flows, which are as if at rest, and in motion;
- acid, meadow;
- saltpeter;
- metals, easily smelted;
- oils.
Depending on that, what substance to heat, electric heaters differ from each other.
Varieties
Despite the general purpose, electric heaters may differ in design.
There are two types of elements:
- double-ended;
- single-ended.
They are all used for water heaters. The first option is the most common, it is part of most water heaters. The second option is cartridge shadows, it is used in a rather narrow professional field. Usually this includes casting plastic products.
Depending on that, what task needs to be solved by an electric water heater, distinguish different configurations:
- flat;
- pipe parts;
- with a collar;
- cartridge.
The use of a flexible complexion is widespread. It is able to heat various components of industrial equipment, items for commercial purposes. Water heaters are a great way to profitably convert electrical energy into thermal energy. During the operation of such a device, a certain amount of water is heated.
Water electric heater
This device is also called a tubular water heater. The name is explained by the composition of the device.
general information
Water electric heater consists of a tube, made of steel or copper. Inside it is a dielectric, conducts heat and filament.
The device works due to that, that the current has a positive effect on the filament, and the dielectric conducts heat to the tube itself, which spreads heat to its environment.
Heaters for water heaters are able to heat water to the required temperature, including to 100 degrees. These can be standard household water heaters, and heat guns, autoclaves. To heat much more water or reach the highest temperature, use tubular electric heaters. They are more powerful, than standard.
Water shades can vary depending on the power, its shape and size, as well as the structure of internal parts. Example, differences may be in the distance between contacts, in the carving. It is important to know about all the features of the device before buying it.
Advantages of devices
The spiral is most often used as a heating element, made of wire. The function of the outer shell is played by the tube, it is made of stainless steel. Due to the properties of the shell, the complexion is airtight, protected from all kinds of damage.
The advantages of electric water heaters can be called:
- versatility;
- reliability;
- security.
The first quality is due to the fact, that the device is able to heat different volumes of liquid to the optimum temperature. The heater is ready to last a long time. Sometimes such a device works close 10000 hours. The device is completely safe, you only need to follow the rules of operation.
Once you have decided on the choice of complexion, it is important to pay attention to the compliance of electrical voltage with other parameters of the product. This is power, its shape and location. In order for the device to last a long time, it is important to periodically clean it.
