Electric heaters for home energy-saving - the most safe and economical. Overview, Species

Comfort in the house is difficult to provide without a comfortable temperature, especially in winter. The fact that in winter in a residential building must necessarily be warm. Few people like to live in practically Spartan conditions at a temperature of 18 °. Create a comfortable temperature today is easy - in shopping centers and specialized stores a huge selection of different heating appliances is offered. But among all these boilers, cumbersome heating systems, household electric heaters are the most simple to operate. They operate from the power grid, are characterized by high heat transfer, mobility, and easy connection.

In some cases, the electric mobile household heater can be used even as the main heat source. However, most often they are used as auxiliary devices. For example, these devices are very helpful when the apartment or house is already cold, and central heating has not yet been connected.

It is believed that these devices "with an appetite" refer to electricity. Earlier it was really so, but the new generation electric heaters are quite economical, which makes them so popular.

Types of devices by the principle of action

These useful devices perform one task, but they do it differently. So, three ways of heat transfer are distinguished:

• Natural convection.
• Thermal ventilation.
• Long-wave radiation.

Convection is mixing. So, warm air is easier, which means it will necessarily rise upwards. In its place will fall cold air, which is denser and heavier. The mass of models that work on this principle have a radiator structure. The most common among such devices are various oil heaters or convector panels.

Thermal ventilation or forced warm air is used in heat guns or heat fans. In the construction of such devices - actually a fan and a heater. Air forcedly passes through the heater, reaches the desired temperature and is blown into the room. Sometimes you can find on sale systems that are combined. Here, convection type devices are equipped with fans.

The principle of heat transfer by means of long-wave radiation is very different from that in the above types of devices. So, the IR heater, like the rays of the summer sun, heats the pieces of furniture and surfaces in the room, and already the air is heated from them. These structures have a halogen, quartz or carbon lamp as the heating element.

Heating elements of modern heaters

By design, heating elements can be divided into tape-needle, devices in a protective casing, monolithic. Let's consider each of them.

Stranded needle

In convectors and panels of this type, several types of elements are used. The simplest and the least secure is the needle-shaped strip heater, otherwise it is called "Stich". Manufacturers make a lot of efforts to improve the safety of these products, but this element is not protected from splashing any liquids. These devices can not be called safe, besides they are very cheap, uneconomical and do not have thermal inertia. Experts do not recommend installing and operating these devices in rooms where moisture or steam can form.

Heater in protective casing: structural features

It is already more advanced elements - with protection and external grinding. Inside, the casing is filled with insulating materials, which also have excellent thermal conductivity characteristics, such as magnesium, quartz or ceramic insulators.

Often, the fins on such heaters are made of aluminum. The shape and number of plates can be different, depending on the tasks and the cost. The most effective are those where there are more such ribs. Such electric heaters for home - energy-saving. These devices are able to quickly heat even the largest rooms and at the same time require a minimum amount of energy. With regard to safety, the design has a high degree of protection and is not afraid of moisture. You can install the heater even in the bathroom.

With all the merits, there are some, however, very minor, shortcomings. Heaters in the casing crack. This happens because of the different coefficients of expansion of aluminum and steel. As a result, the effectiveness of the device will decrease over time.

The most efficient heating element

The most expensive and effective devices are those equipped with a monolithic heater. Here the consumer is offered a case with ribs made of aluminum and other metals alloys. Inside - dielectric materials.

When the heater is running, there is no noise, the service life is much higher than that of other devices. These are excellent electric heaters for the home. Energy-saving technologies here allow decently to save on electricity.

Thermoregulators

Many modern convector household heaters are equipped with modern and technological thermoregulators or thermostatic units. These control systems allow the user to not only set the desired temperature, but also maintain it at a level. In the circuits of these control devices, the latest sensors are used that control the air temperature. Often on most models, they can be found at the bottom of the case.

There are several control options that are equipped with popular types of electric heaters. These are mechanical systems, electromechanical control, fully electronic systems.

Economical technologies

Those people who decide to pick up a suitable modern heater for themselves need to know that in order to maintain the set temperature, high accuracy is not required. But in order to ensure the economy of work, it is simply necessary.

Modern convector electric heaters for home - energy-saving. This is an indisputable fact. Thanks to the electronic control of the device, much less energy is required than structures equipped with any other control method.

The more accurate this or that thermostat will be, the more economical the heater will be. In modern control systems, timers can be set that allow the user to set the time when the device must turn on or off. You can also set the length of time that the system will work.

In addition, most modern devices have high safety characteristics. In the event that the unit overheats, protection will be activated, which will disconnect it from the network.

Manufacturers also offer devices with central control. It is possible to organize the operation of several convectors, which are connected to a network.

The newest electric heaters

Everyone knows what infrared heaters are, oil and convection heaters . But manufacturers do not cease to amaze the consumer. Recently began to appear solutions based on ceramics.

Ceramic heaters provide a small panel failure. The thickness of this panel is not more than 4 cm. These thermo-ceramic heaters can be used both as an additional heating element, and as the main source of heat.

The front part of this structure is made of ceramics. Also manufacturers can use talcomagnesite, which is a thermal energy storage. During the operation of the device, this panel warms up, and fairly evenly. When the power is turned off, the panel will slowly cool down, and heat will be given to the room.

The front panel of similar devices emits infrared waves. They are similar in their properties to the familiar sunlight. So, the IR heater can maintain a comfortable, uniform temperature regime throughout the room. In addition, the temperature support will be as economical as possible.

In addition, the room is heated by convection of air masses along the rear wall. The air streams heat up and give heat to the room. So warm up about 30%. This is a very effective and economical solution.

When air passes through the back wall of this device, all pathogenic microbes are killed. Thanks to talcomagnesite, the air is not only thoroughly heated, but also ionized.

For today it is the most economical electric heaters, which also have a high level of safety. This device can be hung on the wall where it can perform decorative tasks. These devices have a great appearance and can decorate the room.

Infrared solutions

These are also popular electric heaters for the home. The energy-saving characteristics of these devices are also at an altitude. These systems are good in that they can perfectly give off heat even in open areas. Even if the window is cloudy and cold, these instruments can feel the cozy warmth, which somehow resembles the sun's rays. This equipment is most suitable for apartments and houses, and their quality and safety are recognized in all countries of the world.

If the house has small children, then it is worth buying such electric heaters. Their price is quite affordable (from 3 to 7 thousand rubles), and in return they will ensure the health of the child. This is one of the safest and most economical solutions.

Types of infrared heating, advantages and disadvantages

There are several options for heating with the help of such devices. This can be local, economical heating. It can also be the heating of certain areas in the room. Devices do not have the inertia - it is only necessary to turn on the device, and it will immediately begin to give off heat. If it is decided to stop the choice on infrared options, then let it be a device with carbon lamps.

Among other advantages - universality, safety, ease of installation and operation. The economy is at a very high level. But the only drawback is the price. For example, an infra-red electric wall heater will cost much more than traditional oil or convection solutions.

Reviews

Many people do not believe and doubt that an electric heater can be efficient, convenient and economical. The economy and safety are proven. Perhaps someone else will be able to recall that several decades ago in each office of a children's polyclinic there were infrared devices.

Is this electric heater really economical? Reviews about the devices say that yes. If there is preparation in a residential building, if the heat loss is zero, then the savings will be "evident".

The choice in favor of economy and safety

If you need to heat an apartment building or any other room, but gas is expensive, you can always use modern technology. Manufacturers create the latest equipment. It is no longer Soviet electric heaters for the home. Energy-saving technologies have already taken more than one step forward, which means that today the price of heat and coziness will be minimal.

So, we found out what the electric heater is, wall-mounted and not only.
