I'm not sure if this has been thought of, so I thought I would throw it out here and bounce it off of everyone to see what everyone thinks.
I was thinking about ways to save money by heating and one of my thoughts was setting up a solar water heater outside at ground level, a using it in a thermosyphon setup with one or more of the liquid baseboard heating setups.
These baseboard units comes to mind:

Closed system with antifreeze, expansion tank, etc.
Thoughts on the idea?
Thanks in advance for the replies.
