5 situations.
1. The solar water heater outlet is blocked. On the top or side of the water storage tank of the solar water heater, there are usually air outlets for pressure relief and exhaust to prevent water in the storage tank from solar water from expanding and rupturing the water tank due to excessive volume pressure during use.
2. Heating process. This water outlet is easily blocked.
3. Dirt and dust from the external environment.
4. Scale is generated when connected to the water tank. If used for a long time, the air outlet filter will become clogged. Once clogged, it will cause poor drainage and low water flow. Additionally, it may also be caused by the air outlet hose being bent. Although it does not affect the exhaust pressure, when we use water, the air inlet is more ddifficult and the water flow will be low. If there is a liquid accumulation tank at the top, check if the liquid accumulation tank is blocked.
5. The outlet pipe is bent.
Solar energy is a renewable energy source. It refers to the radiant thermal energy of the sun (see the three modes of propagation of thermal energy: radiation), and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
