I've been thinking about that too. Add-on green houses or 'sun rooms' are
pretty nice heat sources when south-facing.

If you installed one using some good thermo-pane windows, and had the whole air-space well insulated, you could just pump the warm air into your home using a simple fan.

But, if you went with plain glass or plastic, you would need to get the air space up around 50 to get good results with the reverse AC unit..
The larger the air space, the better!
