Solar water heaters are equipped with an auxiliary heating system (i.e. electric heating) when there is insufficient sunlight (in winter) or no sunlight (such as at night or on rainy days), in order to reach the set temperature. , the electric heating system will be automatically activated. The electric heating system The electricity consumption of each brand is different. It mainly depends on the water storage capacity, heating tube power and hot water consumption. product nameplate.
Your current situation seems to be that the water is not heated at all or is not heated on time. If you use a large amount of hot water at home, this is a normal phenomenon. If the user's funds are not very tight, I will recommend it. When installing a dual water heater system, I recommend rural users to purchase heaterslarge-capacity solar water heaters and double-layer insulation of hot water pipes.
Power consumption, but it depends on the situation.
Water heaters have different usage habits depending on the season. During cold winters, keeping the water heater on will save energy. Because the temperature in winter is low, the water heater will consume a lot of electricity when heating starts, and the water temperature requirements for bathing in winter are very high. How comfortable it is to take a hot bath. In the hot summer, you can turn off the water heater if it is not in use. The temperature difference in summer does not change much, which can boil water quickly and save electricity.

Notes:
1. burns: The water that flows from solar energy is usually water from the pipe.The temperature is not high at first, but in summer, the water temperature in the solar water heater can even exceed 90°C after the cold. the water in the pipe is discharged, the hot water will be above 90 degrees Celsius. Water will spurt out and users will often be burned if they are not careful. When taking a bath, you should be careful of the cold. The water stored in the water pipe is first released. Once the water from the solar water heater flows out, the temperature suddenly rises and causes burns.
2. Regular Inspection: Regularly check whether the pipes, vents, and other components of the water heater are functioning properly. Check all the important parts of the water heater one by one to avoid damage to the water heater components.
3. Lightning Protection: It is strictly prohibited to use solar water heaters during thunderstorms and windy weather. The main reason is thatSolar water heaters are usually installed on the roof. It is easy to guide lightning during thunderstorms. and prevent lightning.
4. Anti-clogging: Clean the shower head frequently, because impurities will be generated in the water after being exposed to the sun and transformed into hot water. Over time, impurities will easily clog the shower head. . Therefore, it needs to be cleaned or even replaced frequently to avoid clogging.
