Temporary Solar Heater Idea

[mas985]

Temperature rise is proportional to the area of the solar panel and the efficiency of the device. A garden hose will be much less efficient than a solar panels so you will need more area to get the same temperature rise. Assuming the hose is 3/4" wide, for every 100 sq-ft of hose area, you will need 1600 feet of hose. My panels are 450 sq-ft which would require 7200 feet of hose. Not very practical.
