Practically off the grid!

Solar Water Heating has been a great resource for me when making any decisions about solar heating.  I find myself going back to it time and time again for sizing and system design ideas and I’ve never felt the need to buy another book on the subject.  

It offers a detailed comparison of flat plate and evacuated tube collectors, air and water collectors and shows schematics for many active solar heating systems.  It also offers descriptions of each component used in the systems which is great information for the average do-it-yourselfer and there is even a section on high mass seasonal heat storage sizing for those of you really going all the way off the grid.
