By nesting two copper coils in this way we can fit over 80 feet of 3/4" pipe into a 2 ft. cube. The outer coil will have a diameter of 2 ft. with 8 loops giving us 2*3.14*8 = 50.24 ft. of pipe. The inner coil will have a diameter of 1.5 ft. also with 8 loops giving us 1.5*3.14*8 = 37.68 ft of pipe, for a total of 87.92 ft. Our calculations indicate that this will provide us with a significant increase in the temperature of the main water before it enters the electric hot water heater.
