The only way is to take it apart and wash it.
Since the inner wire of the hot water pipe valve needs to be washed with tap water for a long time, it will be corroded and corroded. Currently the only solution on the market is to do so. remove rust by hammering and grinding after disassembly.
After prolonged use of the water heater, a certain amount of dirt, corrosion and rust will occur inside the water heater. The formation of scale and rust will affect the efficiency and lifespan of the electric water heater. Many people may think that the water from a water heater that has been used in the home for many years and has never been cleaned is still very clear, and they feel that there is no of scale or other dirt in it. The radiator contains more scale and other dirt and needs to be cleaned urgently.
In the water heater, the mouthof the hot water pipe is at a high location, approximately 2 cm from the top of the covering, while the mouth of the cold water pipe is at a low location, approximately 3 cm from the top of the covering. bottom of the covering. Normally, the water heater At this time, the cold water pipe is still filled with water, the hot water is kneaded to the top by the cold water, and the water flows down the pipe of hot water, while the scale settles at the bottom of the inner tank and will not be discharged through the hot water pipe.
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 arrives, you can boil water in advance 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. The pipesExteriors 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.
