Why? Looking for some metrics...
The question is:
1...Cold vs preheated combustion air differences might be relevant in theory and worthy of discussion but is it really significant with regards to pellet stoves?
"Process temperature is customarily used as a rough indication of where air preheating will be cost effective. Processes operating above 1,600° F are generally good candidates, while preheated air is difficult to justify on processes operating below 1,000° F. Those in the 1,000˚ to 1,600° F range may still be good candidates but must be evaluated on a case-by-case basis. These guidelines are not ironclad. Financial justification is based on energy (or Btu) saved, rather than on temperature differential. If a low temperature process has a high enough exhaust gas flow, energy savings may still exist, even though the exhaust gas temperature is lower than 1,000° F.

So are we in agreement that air traveling through an intake is not being dried?
is heated air drier than not heated air?

Even if the moisture was some whow released by passing down a warm vent, it's still being released in the vent traveling toward the stove... however, if the water molecules dawn their superman capes and take flight against the air stream perhaps they could escape the flames.If air is warmed the RH will go down. It will always contain the same amount of moisture though unless its dripping out somewhere magically.
