1. First, we turn on the main valve and power switch of the solar water heater. At this time, the collector tube will start to work, and the water tank will store cold water and hot water.

Then we set the temperature of the solar water heater. There is a temperature display screen on the surface of the water tank, which shows the actual temperature of hot water stored in the water tank. If the temperature is not enough, we can set the temperature ourselves, and then click "Instant Heat", and the hot water in the water tank will reach the set temperature, so we can take a bath with hot water.
