I am in the process of building & installing an evacuated tube solar hot water maker, a solar hot water tank with electric backup, a 1000 gallon unpressurized water storage tank with copper heat exchangers, and an EKO 40 wood gasification boiler. I am also incorporating a heat dump from Northeastern Radiant that will heat a 60' coil for preheating DHW as well as dump the excess heat from the solar tubes. I have decided to photograph the project & post it here: https://picasaweb.google.com/bobbybandjillian/EnergyIndependenceProject?authkey=Gv1sRgCPyQ5JLYlP63EA I would welcome your thoughts, input, critiques, and comments as this project unfolds. My goal is to have this up & running by September of this year. I will continue to post photos as I progress. Thanks in advance.
