Actually the solar is installed as a pre-heat. Water source comes in to the soloar tank first then output from solar tank to gas tank. When it's working, at noon, the gas tank doesn't have to burn at all. At night, or cold, gas tank turn on.
Now, I think water is still comming through the solar tank to the gas tank since the gas tank keep burning everytime we use hot water, and we do have hot water.
Therefore, I think water is still going through the solar tank, just nothot. But, the 2 pipes from/to the solar panel are extremely hot.
If water doesn't go through the solar tank, I wouldn't have hot water in the shower. Am I right?
tadink, pm you my location.
