The water of the solar water heater will definitely be cold when it encounters continuous cloudy and rainy days, but it also depends on how you use it, because the thermal insulation effect is very good. Previous hot water was not used. and it can be used for several days and it will still be warm. If cold water is added, the water temperature will be a little higher than the normal temperature, and an electric heating system can also be installed inside. installed, electric heating can also be used in rainy days. As for whether to choose a solar water heater or an electric water heater, it depends on your personal preferences and your actual situation.
Can solar water heaters be used when it rains?
There are two reasons why the solar water temperature is 90 degrees on rainy days. rain:
1. The weather was very coldbefore it rains. Well, there is enough sunshine and the water in the solar water tank can reach over 90 degrees or even boil, but almost no hot water is used or the quantity is used less, resulting in heat accumulation. In addition, the water tank has an insulating layer, so the heat loss is very low and the temperature does not drop during the day and night. It is above 5 degrees, so if it rains on the second or even the third day. , it is normal that the water temperature in the water tank remains at 90 degrees, which means that the quality of the solar energy you chose is still very good.
2. Sensor failure. When the sensor fails or the sensor line is damaged, the sensing water level may be inaccurate. If the water temperature is indeed high, it is recommended to do so. There will be no problem. Otherwise, if the water is hotor the temperature is not high, the sensor is defective and must be replaced or the circuit repaired.
Solar power, as the name suggests: uses heat from sunlight to convert energy into machines, electronics...electricity and power. This water heater is the simplest conversion yet to convert into thermal energy. , but in The water heater is equipped with an energy collector. When the heat is sufficient, the water heater works on its own and does not require any other energy support. Therefore, the solar water heater cannot work in the best case scenario. can use the remaining energy from the past. Generally, the water heater can work normally if there is sunshine, but it takes a long time for the water to reach normal water temperature (not too hot, 65 degrees +-).
