What is the appropriate water temperature for solar water heaters in winter?
I can only speak from my personal situation. I am in Liaoning, northeast China, when the outside temperature is minus 25 degrees Celsius. When the water pipes are not frozen, the water temperature is 40 degrees. When the outside temperature is minus 10 degrees, it is basically stable between 50 and 65 degrees. can stay near 95 degrees at midday and reach 50 degrees in the morning and evening. You can In Hunan, you can make a comparison with the temperatures I mentioned

What is the temperature. Can the water from Four Seasons Muge solar water heater be in winter? How many degrees can it be?
I bought their solar water heater, I don't remember what model it is. winter is quite warm. Siji Muge solar water heater uses space tubesx precisely drilled. It has a very strong heat collection capacity. Generally it can be used in one day, I felt that this winter the water temperature is quite warm. even ten degrees.

Is it safe to heat the solar water heater to a certain temperature?
It depends on the duration of sunshine. Generally speaking, the average duration of sunshine. in the North China Plain in winter, it is 7.5 hours/day. In this case, a good solar water heater usually has a daily temperature rise of around 30 degrees. It is recommended not to use it on the day you use it. solar water, but wait until the next day to use it. The explanation is as follows: Good solar water heaters The daily heat loss of Pirulinorite is 4 degrees to 6 degrees. In this case, it will be easier to heat the next day. depending on the original temperature of the water, and the temperature you haveez need can be reached immediately. Generally speaking, the water in the water tank can reach more than 70 degrees in two or three days. In continuously cloudy weather, you can start the electric heating so that double insurance can guarantee that you have hot water every day. Most of the good ones can heat up to 100 degrees, provided there is enough sunlight. Without sunlight it won't work. It also depends on the temperature of the sun. The solar water heater is calculated based on an average annual temperature of 15.7°C, annual sunshine hours of 2014 hours and average annual total solar radiation of 111.59 kcal/square meter. the heat collection area is 2 square meters. The annual solar energy absorbed is 9.37? 106 kilojoules, calculated based on an increase in water temperature of 35°C (the base water temperatureis 10

Why can solar water heaters increase water temperature
Because solar energy is converted into thermal energy###The solar water heater is a device that converts solar energy into thermal energy, heating water to a low temperature. at high temperature to meet people's use of hot water in life and production. According to the structure of the solar water heater, the forms are divided into vacuum tube solar water heaters and flat plate solar water heaters. , accounting for 95% of the domestic market share. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly relies on evacuated collector tubes. The collector tube uses the principle of hot water floating to the top and cold water from theash to produce microcirculation in the water to obtain the required hot water. ###The key part of the domestic solar water heater is the all-glass vacuum solar collector. Pipe (vacuum tube for short), the quality of the vacuum tube directly affects the overall performance of domestic solar water heaters. ### The energy conversion is very environmentally friendly and comes from new energy ### The water temperature of the solar water heater is not only related to the outside temperature, but mainly depends on the quality and performance of the collector tube and lighting. time and intensity of sunlight, tap water temperature and water consumption.
Solar water heaters can be used in winter. Solar water heaters do not depend on the outside temperature for heating, but on ultraviolet rays for heating. The heating tube converts light energy into thermal energymic. , whether it is winter or summer, as long as there is a trace of sunshine, the water can be heated if there is no sunshine, it also has an electric heating system intelligent, which transforms it into an electric water heater.
When the temperature is below 0℃, it is best to use water from the water heater in small quantities and several times a day, especially before going to bed in the evening and after got up the next day. you can put a small amount of water to make the water flow into the pipe and depends on the water temperature to increase the pipe temperature. The lower the temperature, the more water must be drained to prevent water pipes from freezing and blocking.
When using solar water heaters in winter, the amount of water supplied should be determined according to weather conditions to ensure appropriate water temperature during bathing. When the temperature is nott not too low (5-7℃), after using water that night, if there is still hot water in the water tank, it is advisable to refill the heater immediately solar water with water to reduce the water temperature in the tank. water reservoir and heat loss that night; if the temperature is low, it is advisable to fill the water tank the next morning to prevent the pipes from freezing at the outlet of the water heater if it rains or snows the next day, half a tank; of water or more than half of a water tank can be filled according to actual needs.
Particular attention should be paid to the antifreeze of solar water heater pipes, especially the insulation at the connection between the water tank and the water supply pipe . Generally, the length of an insulation pipe. is two meters, and the joints of each insulating pipe must be well insulated. Secure with adhesive tapeyew.
