Suggestions on purchasing electric heaters

In winter, the weather is cold. Although the temperature in the north is low, there is heating supply, and the south is cold, humid and frozen, which requires some heating equipment. Although the air conditioner is comfortable, the air in the closed space is easy to be turbid, and people often blush because of poor breathing. At this time, another practical heating equipment-electric heater, also began to enter the audience's field of vision on a large scale. I believe you don't know much about electric heaters, so Bian Xiao will introduce how to buy electric heaters.

Product quality and price

Comprehensive consideration of quality, performance, service life, energy saving, after-sales service and other factors. Because of the similar appearance of electric heater products, there are still great differences in quality and price because of the different raw material selection and processing technology. General electric heaters are between 300 and 400, such as Midea NDK20- 10E, with a price of 329. The price comes from the internet and is for reference only.

product usage

Before buying, we must first understand the main use of electric heaters at home, which is the bedroom; Living room, study or bathroom, you should choose the products you need according to your own needs. The suggestions are as follows:

1, bedroom: European fast heating stove; Electric heating film type; Youting。

2. Living room: European fast heating stove; Electric heating film type; Youting heater

3. Study room: European fast heating stove; Electric heating film type; Youting quartz tube; Halogen tube; Radiant.

4. Bathroom: European fast heating stove; Heater (dual-purpose for living and bathing).

Electric heater principle

At present, the mainstream electric heaters on the market can be roughly divided into radiation type, heater, European-style rapid heating furnace, electrothermal film type electric heater, regenerative electric heater and heating and cooling type. Each has its own characteristics. Let me briefly introduce the characteristics of each category:

1, the principle of "radiation" heating is that the Ni-Cr heating wire is wound seven times, fired on the precision composite ceramic insulation seat to raise the temperature, and then the heat energy is radiated to the local space by using the lattice reflecting surface to raise the temperature. The temperature rise is quick and intuitive, but it cannot be improved as a whole.

2. The heating principle of "European-style rapid heating furnace" is that 92 aluminum fins are connected in series with black tube heaters to directly heat the indoor air, and then the heat wave is continuously sent into the room by using the scientific hot runner designed by aerodynamic principle. Extremely rapid temperature rise, fashionable appearance, space saving, quiet, safe, clean, overall temperature rise, simple appearance, splash-proof bathroom available.

3. The "electrothermal film electric heater" adopts two electrothermal film composite heaters, which produces double radiation and triple convection effects and sends warmth to every corner in all directions. The new model heats up faster, but it is slightly slower than the European rapid heating furnace. Quiet, safe and clean, suitable for drying clothes, suitable for family use (especially families with old people and children), and weak splash resistance.

4. The heating element of the "heat storage electric heater" is a high-quality precision composite ceramic-coated nickel-chromium heating element produced in Europe and other places. After being fired at high temperature, it uniformly emits heat energy, which has the advantages of rapid heating, strong heat storage and high energy saving. Quiet, safe and clean, suitable for drying clothes, more suitable for long-term use, and weak splash resistance.

5. The heaters of the "air heater" are mostly made of high-quality nickel-chromium heaters combined with high-quality PTC composite ceramics, which are connected in series between multiple layers of aluminum fins, and the heat energy is blown out by a fan. The air fluidity is better than other integral heating heaters, and the temperature rises quickly in a certain space. However, due to its rapid heat generation and heat dissipation, the utilization rate of electric energy is not as high as other integral heating heaters. It is more suitable for use in small space and short time. Besides the feeling of heat, there are many feelings and sounds of wind. Most models have excellent waterproof performance.

6. Because the "oil heater" uses oil as the heat transfer medium, it heats up slowly, smells like oil leakage, explosion and electric oil, and it is cumbersome and inconvenient to move. Moreover, the heat transfer oil is a consumable product, and professionals need to change the oil after a certain period of time. So this product is gradually eliminated by other new electric heaters.

To sum up, generally speaking, "radiation type" is suitable for local heating in an environment where the space is open and the overall temperature cannot be raised. "European-style rapid heating furnace" has the advantages of fast heat production, high unit thermal efficiency, European fashion appearance and space saving, and can be vertical, wall-mounted and embedded. Suitable for rooms with an area of about 15 ~ 30 square meters, with good overall warmth retention effect. The "electric film" generates heat on three sides and has two-way convection, which has a good overall warm-keeping effect and is convenient for drying clothes. Suitable for families with old people or children and more than three people. "Regenerative" heating evenly, saving electricity and energy, and storing heat for half an hour after starting. Suitable for long-term consumers. "Warm air blower" is suitable for people who like the feeling of hot air and are not afraid of drying. In addition, the low-power fan is suitable for the bathroom, especially for the baby to take a bath and keep warm.

Main practical functions

1, "Intelligent Temperature Control Function" It consists of two parts, one is the temperature sensing unit, and the other is the control unit. The indoor temperature is sensed by its own temperature sensing unit, and then intelligently switched by the control unit without manual control. You just need to set the temperature value. The advantage of this function is not only convenience, but also effective power saving.

2. "Negative ion function" Ion particles in the air are divided into positive ions and negative ions. Generally, bacteria, dust and toxic and harmful gases all carry positive ions. After adding the negative ion function, a large number of negative ions are generated and actively combined with positive ions carrying bacteria and other substances, thus effectively reducing indoor bacteria, toxic and harmful gases and purifying indoor air.

3. "Humidification function" Because the indoor temperature rises after heating, there will be some water loss, so the humidification function can effectively make up for the water needed by the human body. Air humidity is also an important indicator of environmental comfort.

4. "Reservation and Timing Function" Reservation is to automatically turn on the machine according to the specified time, and timing is to turn off the machine according to the specified time.

5. "Remote control function" Generally speaking, anyone with remote control function has intelligent temperature control function.

Relationship between power size and use area

First of all, the heating effect does not depend entirely on power, but also on thermal efficiency, available area, height, sealing and personal sensitivity to temperature. Generally speaking, taking the European rapid heating furnace as an example, 1500 watt is suitable for the environment above 15 square meters; 1600W and 1800W are suitable for 20 ~ 25m2 environment; 2000 watts and 2200 watts are suitable for an environment of 25 ~ 30 square meters.

Precautions for use

1, direct washing with water is prohibited;

2. It is forbidden to completely cover the hot outlet;

3, it is forbidden to tilt, dumping when using.

The above is the introduction of several major factors that need to be considered when purchasing electric heaters. When purchasing electric heaters, we must seriously consider the appeals and suggestions, and carefully analyze the actual situation and actual use of the family before purchasing, especially for families with old people and children, we must choose carefully and do not choose directly at will. In addition, big brands, such as Midea, Pioneer and Gree, are preferred when purchasing. Generally speaking, the quality of big brands is guaranteed, and at the same time, they should also use formal channels to buy, beware of counterfeit and shoddy products.
