There are several possibilities: 1. If water is supplied to and from a single pipe, there is a lot of cold water in the pipe and the cold water in the pipe must be drained before it can get any hot water. 2. If it is a circulation pipeline, the sensor may fail and the temperature is incorrect. 3. If you use an electric heater to heat it to this temperature, the sensor may be closer to the electric heater and further away. of the water outlet, so that the temperature of the water tank is low.
The possible reason why solar energy does not produce cold water but not hot water is that the heating pipe of the water heater is damaged. If this is the case, the affected components must be replaced. time. Of course, it is possible that the circuit board inside the water heater is damaged, requiring you to contact after-sales service.you for the interview. There may be too much scale inside the water heater, affecting heating efficiency. This requires users to clean the inside of the solar water heater regularly.
