Green IT. Solar space heating -- active and passive solar projects for space heating. Getting Started. Solar Water Heating Projects and Plans. Solar water heating systems have a good economic payoff, and are manageable systems to install or build as a DIY project. Some of the solar water heating designs are very simple and low cost. You can save as much as $7000 by building your own system. There are just over one hundred projects with full construction details listed below -- all free. The projects range from simple batch heaters for warm climates through closed loop and drain back systems that will work in any climate. One of the systems is our own $1,000 solar water heating system that has provided a solar fraction in excess of 90% through our cold Montana winter. My thanks to the people who have built systems, and then taken the time to send in pictures and descriptions for others to use.
