Free Energy

Last summer when I wrote about our solar water heater installation, I was anxious to see how it would function during the winter. As an example, right now it is 10am, and 29 degrees outside, and the temperature sensor on the panels currently says 111 degrees. Overall, I have been surprised at the number of days that the system has come on, and it consistently pumps out water in excess of 100 degrees when it does run.
