As seen in the February/March 2012 issue of Mother Earth News. A double duty, DIY solar space heating and domestic water heating project.
http://www.motherearthnews.com/do-it-yourself/solar-water-heater-zm0z12fmzphe.aspx#ixzz1m5toGdPyThis simple solar water heater provides both domestic hot water and space heating. You can adjust the size and design to meet the needs of your home. You’ll find nearly all the materials at your local hardware or lumber store, and to build it, you need only basic carpentry skills and a little plumbing know-how. Amazingly, the cost of this DIY system is only about one-eighth of what you would pay for an equivalent commercial system!
A guide to building this system, and the inspiration for the article, is available on http://www.builditsolar.com. For lots of photos, advice, sizing calculators, and more, visit http://www.builditsolar.com/Projects/SpaceHeating/DHWplusSpace/Main.htm.Using all new, high quality materials, this system can be built for as little as $2000 -- about one 1/8th the price of an equivalent commercial system.
Nearly all of the materials will be available at your local hardware or lumber yard. The system can be built with simple tools, and with ordinary DIY skills.
There are more than a 100 pages that cover the design, construction, and economics of this system and also provide many other alternatives along the way. So, think of it as book, and use the Table of Contents below to navigate around.
