OH,OHHH>>>> I got this one. It Depends
I agree Waldo. If the stove has fixed air control, pretty much you're just moving heat around. I'm sure taking heat off the surface would allow a faster rate of transfer. Not sure how much faster, if any. However, if the stove has a bi-metallic primary air damper, blowing heat off the stove would cool the stove mass. This would cause the flapper to open, and allow more air, which would create more heat.waldo lemieux wrote:OH,OHHH>>>> I got this one. It Depends
I agree with this logic.. Conducting heat from the metal by passing cool air across it should also mean you are conducting more heat from the contents burning inside the stove.. It also makes for better distribution of that heat. BUT, by cooling the metal, the radiant heat may sag a little. Overall I think the fan is goodKLook wrote:The cooler the outer surface of the box, the more heat is transferred.
