Where is the best place to install a solar water heater?

1. It is best to install the solar water heater on a platform.

2. In addition, because the longitude and latitude are different in different regions, the sun's radiation angle is also different. In order to make full use of solar energy, the installation angle will vary from region to region.

3. Install solar energy in a sunny place, usually at the highest point of a building. In China, it is usually on the top of a building, villa, or house. The collector faces due south. If it cannot be due south, it can generally be adjusted within 45 degrees. This ensures that the collector can receive sunlight throughout the day. Since the collector is composed of vacuum tubes arranged side by side, it is more affected by wind, so it is in principle in the direction of the main wind direction of the season.

How to drain water from a solar water heater

1. Turn on the valve, it is connected to the main water supply, separated by a solenoid valve in the middle. Once the check valve fails, the water in the solar water heater will flow back into the main pipe entering the house.

2. Especially in spring, summer and autumn, the water in the solar water heater sometimes reaches above 90℃. Once it enters the main pipe of the household with a material whose temperature resistance is below 60℃, it is easy to scald it, causing water leakage and loss.

3. Drain the hot water in the water tank directly from the tap. The water stored in the vacuum tube cannot be drained. You must remove the vacuum tube to drain the water. If you don't want to use it, you can leave some water in the water tank to prevent it from bursting.

Will the solar water heater be blocked?

Under normal pressure, when the water temperature is over 50℃, the household solar water heater will decompose the calcium and magnesium ions dissolved in the water, such as calcium bicarbonate and magnesium bicarbonate, during the heating process, releasing carbon dioxide and turning into insoluble calcium carbonate and magnesium carbonate, which will precipitate and form scale. If it is not cleaned for a long time, the solar water heater will be blocked. Otherwise, it will not be blocked. It is recommended to clean the scale regularly.
