A drain back system might introduce air into the loop, and we don't want that. How about instead of an extra coolant loop you divert the exaust? Once the correct temperature is reached the exaust goes back to its usual route, thereby not heating the coolant any more. The coolant is still flowing through the exchanger, which by now may be used as an extra radiator.
