Do electric heaters emit radiation
Do household electric heaters emit radiation? In fact, as long as it is an electrical appliance, it will generate radiation, and electric heaters all use electricity, so electric heaters have radiation. The radiation of electrical appliances can be divided into two types: harmful and harmless. The radiation of electric heaters is a kind of electromagnetic wave radiation. Generally, when purchasing electric heaters, we can see the electromagnetic frequency value of this product from its label. Under normal circumstances, the electromagnetic frequency of the electric heater is only 50Hz. From this value, we can know that the radiation of the electric heater will not pose a threat to us, so everyone can use it with confidence. However, for pregnant women during pregnancy, it is still necessary to use electric heaters as little as possible, so as not to affect the fetus.
Which household electric heater is better
1. Oil-type electric heater
This electric heater is filled with a new type of heat transfer oil. When the power is turned on, the heat transfer oil around the electric heating pipe is heated, and then the heat is dissipated along the heat pipe or fins. When the oil temperature reaches 85 ℃, its temperature control element will automatically cut off. This kind of electric heater heat transfer oil does not need to be replaced, it can be used for more than 5 years, and the price is generally between 400 and 500 yuan.
There are 7, 9, 10, 12 and other types of oil cooling fins. The power can be adjusted by selecting the number of fins. The higher the power, the higher the heat. Therefore, for users with different temperature needs, they can choose oil-type electric heaters for heat regulation, which is more convenient.
2. Halogen tube heating heater
Which electric heater is better? Halogen tube heaters have the advantages of high thermal efficiency, non-oxidizing heating, and long service life, and some models also have additional functions such as timing, rotation, and humidification. Halogen tube heaters rely on light to dissipate heat. Generally, 2~3 halogen tubes are used as heat sources, and the power consumption is about 900~1200W. It is more suitable for rooms with an area of about 12 square meters. Some more advanced products have automatic fall Power off, automatic shaking head and other functions, the design is simple and practical.
3. Electric heating wire heater
This kind of heater, like an electric fan, generally consumes about 800~1000W of power. The whole room is heated, suitable for small rooms under 8 square meters. The new product also has the functions of ultrasonic humidification, release of oxygen-carrying negative ions, and wide spectrum. The disadvantage is that the temperature drops quickly after shutdown, the heating range is small, and oxygen is consumed, and the heating wire is prone to breakage after long-term use. Since the cost of the heating wire itself is relatively cheap, if the wire body breaks, the maintenance will not be overburdened.
4. Carbon fiber heater
The carbon fiber heater is a tubular heating element made of carbon fiber as the basic heating material, and uses the reflective surface to dissipate heat. Integral vertical straight barrel type and rectangular floor type: the straight-through type generally uses a single tube for heating, and the body can automatically rotate to heat the entire room. After the power is turned on, the heating speed is fast. The body feels hot in 1~2 seconds. The surface temperature can reach 300-700 degrees in 5 seconds, and the power can be adjusted between 600~1200W. The rectangular floor type adopts double-tube heating, which can be used on the floor or on the wall. The power is relatively large, about 1800~2000W.
5. Ceramic heating element heater
This heater does not emit light when working, has no open flame, no oxygen consumption, soft air supply, and has Automatic thermostat function. The output power of the PTC ceramic heater is 800-1250 watts, the temperature can be adjusted at will, there is no light consumption during work, there is an automatic switch device, high efficiency and energy saving, power saving and safety. Ceramic heaters are mostly used in bathrooms and some small bedrooms. The ceramic heating speed is slow, but the storage heat effect is good, which is more suitable for families with the elderly and children at home.
6. Electric heating film heater
The electric heating film heater uses a fully transparent high temperature electric heating film as the heating material, and adopts a hot air duct structure to transfer heat. The method is to strengthen the convection, the hot start speed is fast, the air outlet temperature can reach more than 100 ℃ within 3 minutes, but it will cool down quickly after the power is cut off. Because the electric heating film is not oxidized by itself when heated, the service life can be 100,000 hours, and it has the characteristics of small size and beautiful appearance. Siphon Heat Pipe Heater This is a new type of electric heating film heater, which uses a “two-phase closed thermosiphon” as the heat source, with fast heating and high thermal efficiency. It does not emit light, has no open fire, and is not afraid of water spray and water vapor corrosion during work. It is suitable for ordinary rooms and bathrooms. The price is about 400 yuan.
7. Convective heaters
This kind of electric heater has an air outlet on the cover and an air inlet below it. The heated air rises and flows out of the outlet, while the surrounding cold air enters the supplement from the inlet. This repeated cycle, so that the indoor temperature can be increased. When the inlet and outlet are blocked or the ambient temperature is too high, the temperature control element will automatically cut off the power supply of the electric heating tube. This kind of electric heater uses about 800 watts of power, and the power can be adjusted by increasing or decreasing the number of electric heating tubes connected. The electric heater has high safety performance and quiet operation, but the disadvantage is that the temperature rises slowly.
8. Quartz tube heating element electric heater
Quartz tube heating element electric heater is mainly composed of sealed electric heating element, parabolic or arc surface reflector, It consists of protective strips, power adjustment switches, etc. It uses a quartz radiant tube as an electric heating element, and uses far-infrared heating and energy-saving technology, so that the far-infrared radiation emitted by the far-infrared radiating element is absorbed by the object and directly converted into heat energy to achieve the purpose of heating.
