Yep, got the blowers.
As to slower convective heating overcoming heat loss, I don't know. I look at it much differently. I have these enormous heat sinks as my exterior walls. They're un-insulated stone (as any proper old house is), which stay at 52F all winter long, whether it's 60F or 80F indoors, or 0F to 30F outdoors. If you put a radiant stove next to that heat sink, it's just going to suck up all the energy that you radiate toward it, leaving only a fraction of the heat you're producing for heating your home. At the same time, my boiler has relatively little trouble heating the same space from 60F to 70F in a short period of time, via convective copper fin-tube radiators. So, the key seems to be heating the air within. Forget ever trying to heat this space by radiating energy into the objects around the stoves, since 80% of the objects facing the stove are cold stone, well-sunk to earth.
I have hard data to back up this thinking, as the amount of wood I've consumed over the last four years has a BTU value several times the relatively small amount of oil I've saved. Burning 5 - 6 cords per year, I was saving maybe only 500 gallons per year, based on the short periods of no burning I have to compare. That amount of wood (all ash, oak, walnut) should have BTU equivalence to almost 1000 gallons of heating oil, so even though my estimated savings are definitely subject to debate, there's no arguing I was throwing away a large chunk of the heating coming off those Jotuls.
