The cold winter is coming, what is the best way to keep warm in winter?

The strongest cold wave in the second half of this year has already arrived. In addition to strong winds and temperature drops, there will also be widespread rain and snow. According to the analysis of Hu Xiao, chief meteorological analyst of China Weather Network, the cold air will affect my country from west to east, and the temperature in most areas will drop by 8-10℃, and the temperature drop in some areas may reach 12-15℃, and above 16℃ in some areas. Most areas will also be accompanied by 4-6 northerly winds and gusts of 7-8.

In order to cope with this cold wave, many regions have also launched a timetable for central heating and are ready to implement heating. Friends in the northern region can finally enjoy the cold wind outside and eat ice cream in short sleeves indoors, but how can friends in the south keep warm in the cold and wet winter? Of course, "shivering" is not enough. At present, there are many types of heaters in my country. We can choose the heating equipment that suits our needs according to the actual situation.

In terms of effect, China's heating equipment is basically divided into two categories: whole house heating and local heating. If the family has a large population, it is better to choose whole house heating, represented by air conditioners, air energy heat pumps, and gas wall-mounted boilers. If you live alone, local heating is also possible, represented by oil heaters, small solar heaters, and baseboard heaters, heating fans, etc. As for how to choose these devices, let's continue reading.

1. What to choose for whole house heating: Air energy heat pump > gas wall-mounted boiler > air conditioner

Air conditioning is very convenient for heating the whole house. It can not only cool but also heat. It has fast air output. The temperature of the whole house can rise in about 30 minutes. However, the comfort of air conditioning heating is poor. When the temperature rises, the moisture in the air in the house will be lost greatly and become very dry. It not only causes dry skin, but also ruptures capillaries and causes nosebleeds. Moreover, since the heating of air conditioning is to compress the refrigerant into high-temperature and high-pressure gas with a compressor, condense and liquefy to release heat, this will cause the heating energy consumption of air conditioning to be very high, the thermal efficiency to be low, and the electricity bill to be very expensive.

In addition, there are gas wall-mounted boilers. Wall-mounted boilers can be said to be born for heating, and can easily meet the diverse needs of users' home heating methods and household heating equipment. In addition, it can also ensure the provision of hot water and can be used all year round. And it is not limited to any region. Due to the "coal to gas" policy, many cities in the northern region have also chosen to use gas wall-mounted boilers to replace centralized heating. Moreover, the birth of condensing wall-mounted boilers has more advantages than traditional wall-mounted boilers. It can absorb the waste heat in the flue gas for a second time, greatly improve the thermal efficiency of gas, and effectively reduce the emission of toxic gases by adjusting the combustion ratio of air and gas, combining energy saving and environmental protection.

However, some families reported that the temperature did not rise after using the wall-mounted boiler. This may be because the model does not match the room area. If the power of the selected wall-mounted boiler is too small and the room is large, the wall-mounted boiler will work continuously at full load, which will not only fail to reach the specified temperature, but also produce more exhaust gas, and vice versa. Therefore, when purchasing a wall-mounted boiler, you must choose the power according to the family's living area, so that you can save gas while ensuring heating, and achieve the effect of environmental protection in one fell swoop.

For some families who cannot use gas, don't worry, air energy heat pump is a good way to heat, and it is also a clean energy, which coincides with the "energy conservation and emission reduction" advocated by the current country. It consumes part of the electricity when the heat pump is running, absorbs free heat energy in the air, uses a compressor to convert low temperature into high temperature, heats the water, and transfers it to the room through radiators or fan coils, etc., to achieve the effect of raising the indoor temperature.

This heating method is more energy-efficient. Through DC frequency conversion technology and jet reheat technology, it can obtain more than three times the heat energy for indoor use. Compared with electric heating and gas heating, it has lower costs and is truly low-carbon and environmentally friendly.

2. What to choose for local heating: oil heater > fan heater > small sun

The above are recommendations for whole-house heating solutions. For people who live alone or do not have much demand for heating, local heating does not require installation and is more convenient, so we also provide a local heating solution.

Old-fashioned oil-filled radiator heaters are too large, take up a lot of space and are bulky, which is not friendly to people living alone. With the improvement of technology, the current oil-filled radiator heaters are not only smaller in size, but also safer. Its appearance looks very similar to radiators. The market mainly uses 7-piece, 10-piece, and 13-piece oil-filled radiator fins. It raises the indoor temperature by heating the blades and can provide 10㎡~15㎡ of three-dimensional heating, which is very suitable for use in bedrooms.

Although its heating process is very slow, the heating effect is very good, and the insulation effect of the oil-filled heater is relatively good. After the oil-filled heater is turned off, it will still retain a certain temperature. In order to solve the safety problems caused by the accidental dumping of the machine, many oil-filled heaters now have built-in constant temperature control systems, which can automatically cut off the power when the temperature of the machine is higher than the safe temperature of the machine. In addition, the oil-filled heater can be disassembled to hang clothes on it, which is a big plus for the humid southern region.

If you want to achieve heating in multiple scenarios, you can try an infrared heater. Take the Little Sun as an example. It uses an electric heating tube to generate far-infrared radiation with a wavelength of 2.5μm~15μm to conduct heat energy outward and then use a reflective cover to reflect it so that the heat can be concentrated and transmitted farther. Many people dare not use the Little Sun because they think it is too cheap or has radiation. In fact, although it will be absorbed by human skin tissue and form a thermal effect, it can make the human body generate heat from the inside out, promote blood circulation and speed up metabolism.

What you need to pay attention to is not the radiation problem, but you should not stare at the small sun for a long time. Because long-term exposure to infrared rays will damage the lens, making it cloudy, and may also damage the fundus, causing vision loss. In short, when buying a small sun, you only need to pay attention to the size and power. The prices are similar, and it is a more affordable heating device.

In addition, bladeless heating fans are also good heating equipment. This type of fan generally adopts a tower-style structural design, and the air outlet is a hollow annular air deflector. The air multiplication technology of this type of heating fan can spray about 300 liters of air per second, without the need for a mixed flow fan to ensure that the airflow is sprayed to the entire room. Moreover, it integrates purification, heating, and cooling, and can be used in all seasons like an air conditioner.

This type of bladeless fan heater is not only easy to move, it can also drive the body to rotate left and right, maintaining an angle of about 120°, and the body pitch can also be manually adjusted. When it detects that the indoor temperature has reached the target value, the machine will automatically stop heating. After the temperature drops, the machine can use the heating element to intelligently compensate for the room temperature, thus ensuring the comfort of the indoor temperature. However, the price is slightly more expensive.

In general, there are many types of heaters available at present. We can make comprehensive choices based on family needs and budget, but remember to choose formal channels to ensure product quality and safety of use, and after-sales service will also be more guaranteed.
