Yes, See this thread.

I have more than doubled the CFM of my blower. The output temps were reduced but the air is moving at a higher velocity. I believe the heat was distributed faster as my recover time(time it takes to bring the temp up to satify the stat) was decreased.
Lots of folks here have mentioned having there stoves set on low heat settings, But keep there fans on high. Distributes the heat about faster IMHO. As long as you can stand the extra noise.
Sorry, I meant combustion air. Same feed of pellets compared to a change in combbustion air measured by the thermometers in this thread. I've seen threads where different flames are supposed to be better but this setup for reading the stove temperature looks great for testing which flame causes a hotter stove.

If you want to measure the wood pellet stove heat output accurately and on it’s highest setting, I recommend the $25.00 digital Cole-Palmer and also purchase the high temperature heat probe. Most thermometers do not measure up to 1500 degrees like this one! My Avalon Astoria on low is 250 and high is over 600 degrees F !!

This meter has a 4-ft. ribbon micro-cable that allows you to place the probe within an area and close the door without affecting the probe or the door seal. Accurately monitor temperature within freezers, water baths, heating blocks, incubators, refrigerators, and other areas. The meter includes a fast-response type-K probe that can be used for general purpose applications. Users can also choose from a wide verity of probe sold separately for surface, liquid, air or semi-solid materials.
What�s Included:
one beaded-wire type K probe, NIST-traceable certificate, leatherette case, and one 9 V battery

I have read some posts that seem to claim such & would guess that the more air that blows outside, the more heat wasted?j-takeman said:earlll said:j-takeman said:earlll said:Has anyone tested to see if more or less combustion air results in better heat for the room?

My fault I didn't catch that. Some of the newer stoves have combustion speed trim. Basically the same as opening/closing the damper more. Closing the damper or lowering the combustion speed would send less heat out the vent. But there could be a price as you might get a rich condition. The burn might turn dark or sooty on you.
But if the flame is a blast furnace? You might be able to reduce it with blower speed or closing the damper some. What brand stove do you have?
