What is the reason that solar energy has no hot water?

What's wrong with solar energy without hot water

1. If cold water comes out, but there is no hot water, it may be because the heating pipe of the water heater is damaged, or the circuit motherboard of the solar water heater is faulty and needs maintenance.

One possibility is that the hot water pipe is blocked. Because it has not been cleaned for a long time, there will be more scale bacteria inside, which will affect the heating effect, so it needs to be cleaned regularly.

Precautions:

1, make a comprehensive inspection before winter.

Before entering the winter, conduct a comprehensive inspection of the solar host and pipe fittings, and replace the damaged parts in time to prevent accidents in cold winter weather. Users who do not use solar energy in winter should ensure that the water tank is full of water to prevent the vacuum tube from exploding and the rubber ring from being damaged due to thermal aging caused by long-term air drying.

2. Determine the water consumption according to the weather conditions.

In order to prevent excessive heat loss, it is necessary to look at the water in the sky, that is, to determine the amount of water according to the weather forecast, so as to get a satisfactory water temperature. If it is sunny tomorrow, you can fill it with water. If it is cloudy or cloudy, you can fill half a box of water. It rains all day, so keep raw water instead of cold water.

3. Use electric auxiliary heating to prevent dry burning.

If an auxiliary heat source is installed, the normal operation of the auxiliary heat source device and heat exchanger should be checked regularly. The auxiliary heat source is heated by electric heating tube, and the leakage protection device must be reliable before use, otherwise it cannot be used. When using auxiliary electric heating, special attention should be paid to water supply, and the water in the water tank should not be less than 50% to prevent dry burning without water. Pay special attention to unplugging the power plug when taking a bath, and it is strictly forbidden to use it with electricity.
