Solar Hot Water, High-Efficiency

Does anyone have experience with payback on solar hot water systems in brownstones? This is a four-story brownstone with 6 people. Gas heating, two washer/dryers.

Also, what has been your experience with high-efficiency furnaces — Munchkins, etc.? What kind of payback can be expected? Gennaro was considering this last December — what did you finally decide on?
