Normal use methods of solar energy in winter:
First, the scientific use of heaters and antifreeze . Generally, solar water heaters are equipped with heating and antifreeze devices. Consumers often use it to defrost pipes when they freeze. This not only delays the use of the solar water heater, but also damages its lifespan. The scientific method is this: pay attention to the weather forecast. When the temperature remains below 0°C, the anti-freeze device must be activated to protect preheating.
Don't worry about power consumption, because as the temperature of the heating tape increases during use, the power decreases and the power consumption is minimal. However, when taking a bath, be sure to unplug and cut off the power supply to avoid causing accidents.ed by a loss of thermal balance.
The second is to enter the water depending on the weather conditions. It is necessary to listen to the weather forecast in time. When the temperature is not low (5-7℃), after using water that night, if there is still hot water in the water tank, the solar water heater must be filled. water immediately to reduce water temperature in the water tank and heat loss that night; If the temperature is low, the water should be turned on the next morning to prevent freezing of the pipe leaving the water heater.
If it rains or snows the next day, you can add half a tank of water, or more than half a tank of water according to actual needs, if the water consumption is important, you may want to consider getting started; the electric heating device in the solar water heater.
The third is to open the hot water tap to avoid thefreeze. If the solar water heater is not used for a long time in winter, the water supply tap should be closed and the water in the water heater as well as the upper and lower pipes should be drained to prevent the pipes do not freeze. In sunny weather, the solar water heater can be used normally; When the temperature is below -5°C, it is best to use water from the water heater in small quantities and several times a day.
Especially before going to bed, you can connect a basin of water under the nozzle or faucet, loosen the hot water faucet a little and let it drip slowly to maintain the flow of water in the solar water heater regular and flowing. effectively avoid freezing and blocking of pipes.
Able to take a bath.
The temperature of the bath water should not exceed 42°C in winter. Studies have shown that soaking in water at 42°C for more than 10 minutes pwould cause sympathetic nerve excitation, increase heart rate and blood pressure, and increase the load on the heart. It is not healthy to take a shower immediately after a meal. You should wait 1 hour after a meal before taking a shower.
You should not bathe too frequently. In winter, the weather is dry and the sebaceous glands shrink. Many people also have the habit of bathing every day or every other day. which is not good for the skin in summer. Due to sweating and other reasons, you can rinse it properly every day.
Detailed information:
It is not recommended to take a long bath in winter, and bathing in the tub is usually limited to 20 minutes. Take a shower for 3 minutes to 5 minutes. High temperature bath water may appear to increase body heat, but it does notis not very beneficial for the skin. It can destroy the oil on the skin's surface, cause capillaries to dilate, and worsen the degree of dryness in the skin. At the same time, too high water temperature will increase the load on the heart, causing blood to rush to the skin, which can easily cause cardiac ischemia and hypoxia.
The frequency of swimming in winter should be maintained at Once or twice a week, the water temperature should be close to body temperature. When it comes to choosing a bath liquid, a mild bath liquid is more suitable. The intensity of the scrub should also be moderate to avoid epidermal damage caused by excessive intensity and allow the invasion of external bacteria and fungi. After bathing, it is best to apply a layer of skin care products that can emollient and moisturize the skin.
