Is it harmful to keep warm with the small sun?

Working principle of small solar water heater

Small solar heaters are also called reflective heaters, which emit infrared radiation to a specific space direction through electric heating radiation elements and reflective devices to achieve the effect of heat transfer. At the same time, the directional reflection heat and infrared rays of the reflector are used for heating. Compared with other heaters, small solar heaters have fast heating speed and good durability, but one disadvantage is that they can't balance the indoor temperature and can only be used for local heating.

Harm of small solar water heater to human body

Small solar heaters usually use cellular network to emit energy, and local heating can also easily control hot spots, thus achieving the effect of promoting blood circulation. From this point of view, the small solar heater is harmless to the human body, but from another point of view, it is recommended that you keep a distance of at least one meter during application to avoid skin burns. In addition, the small solar heater will burn the furnace wire red during the heating process, thus emitting a lot of infrared rays, which is harmful to people's eyes, so it is necessary to avoid looking directly at the furnace wire.

Heat dissipation of small solar water heater

The radiation problem of small solar water heaters usually refers to X-ray radiation, external ray radiation and radiation. Ray belongs to electromagnetic wave, but its wavelength is different, so it won't do harm to human body. The electromagnetic wave frequency of ultraviolet rays is generally higher than the harm to human body, but it is still lower than the photoelectric infrared frequency, so it will not cause harm to human body, so you can use it with confidence.

Purchasing principle

Various styles, safety first, choose according to your own environment and space size.

There are desktop, vertical and wall-mounted machines. Desktop heaters are small and exquisite, with smooth vertical lines, while wall-mounted heaters save space. The heater is generally beautiful and generous in appearance, with popular colors such as red, dark gray and blue, which makes the heater quite fashionable. However, when buying heaters, we should also put safety in the first place, such as whether the machine has a device to prevent overheating and overcurrent, whether it has the function of dumping and power off, especially the bathroom heater, which must be waterproof and splash-proof, so we should carefully check whether there is a waterproof sign on the machine. Not seeking the most satisfactory style, but seeking the best internal quality and safety guarantee is the key to choosing a heater.

Buying skills

Tips for selecting heaters:

Precautions 1: Whether it is safe to use, consumers should pay attention to whether it has multiple safety protections such as temperature limiter and thermostat when purchasing.

Note 2: Whether it is environmentally friendly or not, environmental factors are also issues that consumers should consider when choosing heaters. It is best to buy a heater that will not cause pollution and can increase health protection on the basis of safety.

Note 3: What is the brand reputation? When many consumers buy heaters, they often pay more attention to the price and performance of heaters and ignore the brand of heaters. Industry experts suggest that consumers should choose models with higher brand awareness and higher sales when purchasing heaters. Note 4: Whether the quality is in place or not, the quality of the product is also a key issue to be considered in the process of consumers buying heaters. Materials used, product strength, drop tolerance and welding process.

Note 3: Is it economical and energy-saving?

For consumers, only those heaters with high thermal efficiency and high electric energy conversion rate can make the home warmer under the premise of energy saving. Take Yang heater as an example. Some famous brands use high-efficiency ceramic heaters, which have high thermal efficiency and are economical and energy-saving.

Note 4: How about after-sales service?

In addition to the above seven points, after-sales service is also an important issue that consumers should pay attention to. Generally speaking, well-known brands do better in after-sales service.

Note 5: What is the service life?

The service life of heaters is a problem that consumers should pay attention to when buying heaters. Take Yang heater as an example. Some famous brands, such as Midea Yang, have a much longer service life due to the use of X-shaped aluminum heaters.

Note 6: Are the functions complete?

Whether the functions are complete or not is a problem that needs attention. In this regard, many heater brands have done a good job.

Pay attention to use

The power supply of the heater must use qualified three hole socket with grounding wire, otherwise there will be danger of leakage. Because of the high power of the heater, it is not suitable to be used with high-power electrical appliances at the same time, otherwise it is easy to damage the heater. In addition, the socket should not be located directly above the heater to prevent the heat from rising and burning the power supply. Be sure to unplug the heater when no one is in the room.

Three hole socket with grounding wire must be used for the heater, and its technical indicators meet the standards. Never switch to a two-hole socket without a ground wire, because it is easy to generate static electricity, and sometimes it will feel like an electric hand, which is more dangerous. In addition, the socket should not be located directly above the heater to prevent the heat from rising and burning out the power supply. Third, whether there are electrical appliances that are prone to sudden changes in current and frequently used, such as electric welding machines and impact drills. At the same time, it is easier to damage the heater, so pay attention. It is best to use a patch panel with over-current protection device, or choose a regulated power supply.

The heater should not be covered with objects. The surface temperature of the heater is high, and once it is covered with articles, the heat cannot be dissipated in time, which will cause the machine to burn and ignite other articles.

In the installation position, the heater should be placed in a place that is not easy to touch, away from combustible materials, and the back is about 20 cm away from the wall. If you put the electric heater in the bathroom for heating, you should be especially careful to prevent the power supply from encountering water and causing adverse consequences. It is best to install the power socket outside the bathroom, and the wires of the heater should be protected with insulating rubber, which can ensure the connection with the body and avoid contact with water.

Some people like to stay close to the radiator to keep warm, and even put their hands and feet on the radiator, which is very easy to burn. Some people blow heaters directly at their bodies. Although it is warm for a while, it will burn their skin after a long time. So when using the heater, don't be too close to the heater, especially don't let the air outlet of the heater directly heat a certain part of the body.

In dry winter, the skin will gradually lose its surface oil and its moisturizing ability is poor. If the heater is used indoors again, the environment will be drier, resulting in water shortage, chapped skin and itching. Therefore, when using the heater at home, we should find ways to increase the indoor humidity, such as raising some hydroponic plants at home, putting a few pots of clean water, mopping the floor frequently, using a humidifier and so on.
