Why is the hot water from the water heater white?

1, these bubbles are actually air and have no effect on water quality.

2. The boiler exploded because the air entered the water bag, which caused the pressure of the bucket to change when it was heated. However, all domestic water heaters are equipped with pressure relief valves, which will automatically open when the pressure reaches a certain height. Although a small amount of air enters, it will bubble the water, but it will not pose a threat to the bucket, and the pressure does not reach the size of the pressure relief valve, so we can use it with confidence.

3. Air enters the bucket because there is no outlet valve when water is first loaded into the bucket.

4. Scale

Let the turbid hot water stand for a while, most of the water will become clear, and the bottom of the water container will precipitate, which is caused by scale. Scale itself is milky white and insoluble in water, so such scale particles doped in water will cause water to turn white.

5. Hard water

Turbid hot water will become clear after standing for a period of time, and there will be no precipitation at the bottom. If you put water everywhere, you will feel slippery when you touch the inner wall of a container full of water. Strictly speaking, this situation is also a kind of scale, but the scale at this time is not falling off from metals such as heating rods, but just formed or not formed in water.
