The correct way to drain water from solar water heaters

The solar water heater is an environmentally friendly and energy-saving water heater that can convert solar energy into thermal energy for heating. However, when the solar water heater needs to be cleaned, maintained or replaced, the water must be drained. The correct method to drain the solar water heater is as follows:

Step 1: Close. the water supply valve

< p>Before discharging the water, it is necessary to close the water supply valve of the solar water heater and disconnect it from the main pipe. This is to ensure that water will not continue to flow into the solar water heater during the water draining process. To close the water supply valve, turn the valve clockwise and to open it, turn the valve counterclockwise.

Step 2: Open the water discharge valve

After closing the water supply valve,you need to open the water discharge valve of the solar water heater. The water discharge valve is usually located at the bottom of the solar water heater. Before opening, the container must be prepared so that the water can flow out without problems. The way to open the drain valve is to turn the valve counterclockwise.

Step 3: Wait for the solar water heater to drain

After opening the drain valve, you need to wait for the solar water heater to drain completely, which takes usually a while. During the ventilation process, you should pay attention to the color and quality of the water. If the water turns out to be dark or smelly, it means that the solar water heater needs cleaning and maintenance.

Step 4: Close the water discharge valve

When the solar water heater is completely empty, you need to close the water discharge valve. This can be done by turning the valve ins counterclockwise. prevent water from continuing to flow.

Step 5: Open the water supply valve and release the air

Once the water is drained, the water supply valve of the heater -solar water heater should be opened again and the air should be discharged into the main pipe to prevent air entering the solar water heater causing malfunction. The way to ventilate is to turn on the tap and wait for a while or until the water flows steadily.

In short, properly draining water is an important step in maintaining solar water heaters. This can not only avoid damage and breakdown of solar water heaters, but also extend their lifespan and improve their efficiency.
