In winter, users who use solar water heaters often find that the hot water generated by them is often difficult to reach the temperature required for bathing. In fact, users can take some smart ways to make the water temperature of the solar water heater meet the demand.
Depending on the weather conditions to determine the amount of water
In winter, the sunlight is not strong and the light time is short, so the amount of solar radiation absorbed by the vacuum tube is greatly reduced. In order to obtain a relatively satisfactory water temperature and maximize the benefits of solar energy, the amount of water can be determined according to the weather forecast. After using up the water at night, if there is still half of the hot water in the water tank, in order to prevent the heat from being lost too quickly, if the next day is sunny, fill it with water;
Smart use of water in the water heater
On sunny days in winter, the solar water heater can be used normally. When the temperature is lower than -5°C, it is best to use the water in the water heater a small amount or several times a day.
When using water in the morning and evening, if the water in the solar water heater is used up but hot water is still needed, you can use cold water for a few minutes at this time, and use the principle that the cold water sinks and the hot water rises to push out the hot water in the vacuum tube, and then I can continue to use it.
Reasonable use of electric heating function
Some solar water heaters have an electric heating function. It is recommended to use this function several times in spring, summer, and autumn to prevent failure or self-damage caused by long-term use, and to ensure normal use when winter comes. If you use a lot of hot water in winter, you can consider starting the electric heating device in the solar water heater or putting the water in the solar water heater into the electric water heater to heat it up slightly.
Wipe vacuum tubes to increase heat collection efficiency
In winter, there is less rain, dry weather, increased dust, and snow in some areas, so dust and snow may adhere to the collector and back plate of the water heater, and the dust and snow cover will make the collector The device reduces the heat collection efficiency. If possible, it is advisable to wipe the vacuum tube to increase the heat collection efficiency.
