Hi Jim,
Then a solar hydronic system is what your wanting at 160ºf average heat available. You already have the water distribution system available. You might want too consider adding a few wall mounted hydronic/fan units too increase your heat flow too a room. The fans can be solar powered very easy and cost effective.
4ftx8ft solar panels are very easy for a DIY project. The underground storage tank is the biggest build of the project. This way you can keep your oil fired back-up on days "if" you run low on solar heating(doubtful but possible).
I'm always very cautious of "I've got a secret way to heat your home" type guys that do not publish there systems in public. Passive solar air systems have been used for thousands of years so it's nothing new. The problem with passive air is that 12hrs of night time air storage is a huge design problem where the same is accomplished with water very easy.
If you have a Co2 problem inside your home, you'll have that problem no matter what type of heating your using. A Co2 problem is caused by not enough outside make-up air.
Most newer homes do have a indoor air quality problem due too the chemical off gassing of the building materials used. This "can" be a very serious problem too some people.

The draft forces are
