water coming from the tank after a days heating and the on demand doing the rest of the heating.
About the middle of march the system began to produce enough hot water that the on demand system wasn't needed any more and even on cloudy days a lot of hot water was produced.
The only problem I encountered was with the soldering that I did myself. I used 1/2 inch
copper pipe and soldered the joints with common solder, make sure and use silver solder as the heat
off the system will melt the common solder and cause leaks (nasty) or better yet use the insulated
stainless pipe you can buy from Latitude51 Solar, its worth it.
My favorite saying to my wife now is WOW! YOUR SHOWER WAS FREE COURTESY OF THE SUN
