Coziness in the house is difficult to provide without a comfortable temperature, this is especially true in the winter. It is a fact that in the winter the living room must be warm. Few people will like to live in almost Spartan conditions at a temperature of 18 °. It is easy to create a comfortable temperature today - in shopping centers and specialized stores a huge selection of different heating devices is offered. But among all these boilers, bulky heating systems, household electric heaters are the easiest to operate. They work from an electric network, differ in high heat emission, mobility, ease of connection.
In some cases, an electric mobile household heater can even be used as the main source of heat. However, most often they are used as auxiliary devices.
For example, these appliances help a lot when the apartment or house is already cold, and the central heating has not yet been connected.
It is believed that these devices "with appetite" relate to electricity. This used to be true, but the new generation electric heaters are quite economical, which makes them so popular.
Types of devices according to the principle of action
These useful devices do one thing, but they do it differently. So, there are three methods of heat transfer:
- Natural convection.
- Thermal ventilation.
- Long wave radiation.
Convection is mixing. So, warm air is lighter, which means it will certainly rise up. In its place will fall cold air, which is denser and heavier. The mass of models that work on this principle have a radiator design.
The most common among such devices are various oil heaters or convector panels.
Thermal ventilation or forced supply of warm air is used in heat guns or heat fans. In the design of such devices is actually a fan and heater. The air forcibly 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 using long-wave radiation is very different from that in the above types of devices. So, an infrared heater, like the rays of the summer sun, heats furniture and surfaces in the room, and the air is already heated from them. These structures have a halogen, quartz or carbon lamp as a heating element.
Heating elements of modern heaters
By design, the heating elements can be divided into ribbon-needle, appliances in a protective casing, monolithic. Let's consider each of them.
Tape Needle
In convectors and panels of this type, several types of elements are used.
The simplest and the lowest level of safety is a tape needle heater, otherwise it is called "Stich". Manufacturers make a lot of efforts to increase the safety of these products, but this element is not protected from splashes of any liquids. These devices can not be called safe, in addition, 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 a protective casing: design features
These are already more advanced elements - with protection and ribbing from the outside. Inside the casing is filled with insulating materials, which also have excellent thermal conductivity characteristics - these can be materials such as magnesium, quartz or ceramic insulators.
Often fins on such heaters are made of aluminum. The shape and number of plates can be different, depending on the tasks and cost. The most effective are those where there are more such ribs. Such home electric heaters are energy efficient. These devices are able to quickly heat even the largest rooms and at the same time require a minimum amount of energy. As for safety, the design has a high degree of protection and is not afraid of moisture. You can install a heater even in the bathroom.
With all the advantages, there are some, however, very minor disadvantages. Heaters in the casing are cracking. This is due to the different expansion coefficients of aluminum and steel. As a result, over time, the efficiency of the device will decrease.
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 fins made of alloys of aluminum and other metals. Inside are dielectric materials.
When the heater is operating, there is no noise; the service life is much higher than that of other devices. These are great home electric heaters. Energy-saving technologies here allow decently to save on electricity.
Temperature controllers
Many modern convector domestic heating devices are equipped with modern and technological thermostats or thermostat blocks. These control systems give the user the opportunity not only to set the required temperature, but also to maintain it at the level. The circuits of these control devices use the latest sensors that monitor the air temperature. Often, on most models, they can be found in the lower part 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 technology
Those people who decide to choose a suitable modern heater for themselves need to know that in order to maintain a given temperature, high accuracy is not required. But in order to ensure the economy of work, it is simply necessary.
Modern convection electric heaters for the home - energy-saving. This is an indisputable fact. Thanks to the electronic control of the device, significantly less energy is required than structures equipped with any other control method.
The more accurate a particular thermostat is, 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 should turn on or off. You can also set the duration with which the system will work.
In addition, most modern appliances have high safety features. If the device overheats, protection will work, which will disconnect it from the network.
Manufacturers also offer centrally controlled devices. You can organize the work of several convectors, which are networked.
The latest electric heaters
Everyone knows what infrared heaters are, oil and convection.
But manufacturers do not cease to amaze consumers. Ceramic-based solutions have recently begun to appear.
Ceramic heaters malfunction a small panel. The thickness of this panel is no more than 4 cm. These thermo-ceramic heaters can be used both as an additional heating element and as the main heat source.
The front of this design is made of ceramic. Also, manufacturers can use talc magnesite, which is a thermal energy accumulator . In the process of operation of the device, this panel warms up, and quite evenly. When the power is turned off, the panel will slowly cool down, and heat will be transferred to the room.
The front panel of such devices emits infrared waves. Their properties resemble the familiar sunlight. So, an infrared heater can maintain a comfortable, uniform temperature regime throughout the room. In addition, maintaining the temperature will be as economical as possible.
Additionally, the room is heated by convection of air masses along the rear wall. Streams of air heat up and give off heat to the room. So about 30% is warmed up. This is a very effective and economical solution.
When air passes along the back wall of this device, all pathogenic microbes are killed. Thanks to talc magnesite, the air is not only thoroughly warmed up, but also ionized.
To date, these are 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
It is also a popular home electric heaters. The energy-saving characteristics of these devices are also up to par. These systems are good in that they can perfectly give off heat even in open areas. Even if the window is cloudy and cold, you can feel cozy warmth on these devices, which is somewhat reminiscent of 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 there are small children in the house, then it is worth purchasing 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 heating options using such devices. It can be a local, economical heating. It can also be the heating of certain areas in the room. The devices have no inertia - just turn on the device, and it will immediately begin to give off heat. If you decide to opt for infrared options, then let it be a device with carbon lamps.
Among other advantages - versatility, safety, ease of installation and operation.
Profitability is at a very high level. But the only drawback is the price. For example, a wall-mounted infrared electric heater will cost significantly 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.
Profitability and safety are proved. Perhaps someone else will be able to remember that several decades ago in each office of the children's clinic were precisely infrared devices.
Is such an electric heater really economical? Device reviews say yes. If preparation is done in the living room, if heat losses are equal to zero, then the savings will be "obvious".
The choice for profitability and safety
If you need to heat a residential building or any other room, but the gas is expensive, then you can always use modern technology. Manufacturers create the latest equipment. These are 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 comfort will be minimal.
So, we found out what a wall-mounted electric heater is and not only.
