Another link for a batch solar water heater here: http://ir.library.oregonstate.edu/jspui/bitstream/1957/15142/1/SolarHeaterManual.pdf (PDF warning)

This one was designed for Oregon. High latitude, not a lot of solar exposure.

If you put this in a normal house, you can put it inline with your existing hot water heater and use it as a pre-heater. You would need to add bypass valves so the system can be shut off and drained in the winter.
