I've looked at the outdoor wood furnaces from Central Boiler. It is a multi-day burning "shed" that gets heat to your central air and water heater via insulated pipes. This seems like the easiest retrofit for wood burning in a house not designed for it. I wonder if it would be hard to use the same loop for going through the solar water heater to do hot water only in the summer, without wood burning, and assist with pre-heating the return in the winter. The price is a little steep, at about $5k to start.
The only thing that I do not like about woodstoves outside of the home, is that you are absolutely reliant on electricity.
I grew up in the U.P. of Michigan, and a lot of people I know up there went to the outdoor system, because there is a lot less cutting and splitting involved with the fire.
