Solar water supply, why are cold water pipes filled with hot water?

The most basic reason for hot water pipes is that the tap water "top water pipe" and the hot water "sewer pipe" share the same pipeline. And the tap water pressure is too low, even lower than the downward pressure produced by hot water under the action of gravity.

1. Under normal circumstances, the tap water pressure is higher than the water pressure in the water heater barrel. After opening the tap, tap water enters the barrel.

2. However, when the tap water pressure is low and the water supply valve is opened, the pressure of the hot water in the solar water heater (mainly the pressure caused by gravity) is higher than tap water pressure. , which will cause hot water to flow through the pipeline. As shown below:
