I saw the AO Smith solar water heater in the mall a few days ago. How does it feel to use it? Friend

I have a friend who uses it. She said the water for sunbathing and bathing is separated, which is better for the skin, especially for children. After all, children's skin is more delicate than adults' skin. She's been using it at home for almost a year, and she said she basically doesn't need to turn on the power except on rainy days, and it heats up pretty quickly on rainy days. You can refer to it
