The hole switch for connecting to solar energy actually incorporates a leakage protector. This is a cap with leak protection. If the water heater has a leakage problem, it will trigger to effectively avoid the danger caused by leakage.
The function of solar vents: For example, when the water in the solar water tank is heated to 100 degrees, the water boils and the generated steam flows out If discharged, there will be no risk of the water tank exploding. At the same time, when the hot water is released, air will enter through the exhaust hole. According to the siphon principle, hot water will flow out without obstruction. , and the water tank will not risk being deflated.
Solar water heaters generally use water upstream and downstream. If water is supplied, it is a cold water line. If the water is draining, it's a hot water line. The supply valven is opened and cold water enters the solar pipe through the valve. When the solar water tank is full, the valve is closed and the solar pipe and cold water pipe are disconnected. Hot water is hot water and cold water is cold. water.
Main hot water valve and water supply valve. Normally the main hot water valve is normally open. Simply open and close the water supply valve each time water is supplied. for the solar pipes to enter the house. There is no slot in front of the valve.
In addition to the water inlet and outlet, there must be an overflow hole in the upper part of the water tank. This hole must be directly connected to the atmosphere to prevent too much water from entering. the water tank to explode the water tank.
The hole near the bottom is generally used for sewage drainage, and a valve should be installed.This valve should be opened when cleaning or draining water.
