is to keep the heat inside the stove body we want less radiation to the outside
off the paint. So more heat on the outside surface the more loss from the
inside stove unless the loss is greater than the heat being supplied from the
stove (not likely(?)). So its not the thickness of the paint and insulating
material of the paint but the color of the surface that makes a big
difference(?) as to how fast the heat will radiate to the outside air(?). <o:p></o:p></span></font></p>
