David:  (A "cdh" answer):
YEP !,   but NOT in any way you are talking about.  I think what you are describing is IMPOSSIBLE !
(Physics doesn't change).   Using a "convential fireplace", (open front, etc), I have (on two different houses that wife, and I, have lived in), built in a (low cost):  "Outside Cold Air RE-HEATING"  system of small blower, blowing in outside "cold" air through the Fireplace, AND up a short ways up the chimney, and back down, and (again) through the "Firing Chamber,  and OUT into Living Area !     My wife shouts:  "Carroll, IT IS TOO HOT IN HERE!".
1)  small blowers, 110 VAC or 12 VDC, can be obtained on the Internet, with a 1-800 phone call, with a Credit Card.
2)  short sections of PVC piping, 2 or 3 inch Diameter: can hook it all together.  Use solid Galv. 4 inch water pipe, INSIDE FIRING CHAMBER, of FIREPLACE.
NOTE: On  E-Mail request, I can forward a short "Ben Franklin's sayings" about:  HEATING WITH WOOD.   Wife, and I, now retired  in an ALL ELECTRIC house, and I have plans to do it here,  (with small  wood burning:   "Cabin Heater", placed in the forced air ELECTRIC air  heating system.  
Sincere      inquiries answered.   /s/ Carroll H.

been researching efficiently ventilated wood burners (advantages:
