Summary: Rapid cycling is better


The efficiency of a furnace is not determined by heat transfer
from the furnace to the house air, but by the fraction of the
generated heat that goes (or doesn't go) up the chimney. To
minimze the heat going up the chimney, one should keep the plenum
as cool as possible, to maximize transfer to the plenum. (I hope
plenum is the right term.) I believe rapid cycling would do the
best job in this regard.
