We just completed a GREAT install in Nampa, ID where we installed a 2 Mystic panel system on the roof of a custom home in Nampa. We penetrated the roof and ran the water lines in the chase areas of the second floor back to the garage. We mounted the solar storage tank above the pressure tank for the well. The customers are very satisfied with the clean look and performance of the system. There are no connections from the roof to the solar storage tank in the garage. The external lines are insulated to ~R19 levels. The expected payback for this system should be less than 2 years.
We installed 2 controllers for the job. 1) Solar Controller to turn on the circulation pump when the panel is warmer than the solar water. 2) Heating control loop starts the circulation pump when the HEAT is called for and when we have 120 degree water in the solar storage tank.
