Since the amount of sunlight received by the solar tube is small and cannot be converted over time, the low heat results in low heating water temperature. Usually, due to continuous rainy weather, the vacuum tube breaks and the air is mixed, or the solar pipe is blocked by something. It is exposed to bad weather all year round and the surface is too dirty, which affects heat absorption.
The reasons for the low water temperature of solar water heaters are summarized as follows: 1. Continuous rainy weather and dark clouds cover the sun, resulting in low solar heat absorbed by solar pipes. Therefore, the water temperature. hot water is low on those days, and the storage capacity if there is less, you can use the electric heating function for heating. When rainy weather comes, you can boil the wateradvance to prepare a reserve. 2. The outer pipe is too dirty and full of dust and impurities, which affects the communication between the pipe and sunlight. Solar water heaters primarily rely on external metal pipes to absorb and convert solar energy. If there is something blocking the sun or covered with dust on the external pipes, it will affect direct sunlight. Exterior pipes should be cleaned of dust and debris. 3. The heater is damaged, the water level sensor fails, and the cold water level cannot be detected. The heat collecting tube has a damaged opening through which air or scale impurities enter, and the vacuum state is lost, preventing effective heating. carried out. The vacuum line should be cleaned or repaired, then the water level sensor should be inspected.
