I've heard nothing but rave reviews about the Coal-trol.
With that said, I don't own one, But I will say my Channing III is an amazing heating unit as far as I'm concerned, going on 5yrs now.
Your description is a bit ambiguous and there are many varibles that we don't know about that may inhibit your efficiency.
1st, the reostat setting on you Alaska stove will vary quite abit...some people's #1 is anothers #2-1/2 ... calibration on these are not very precise.
Do you have a Barometric Damper? Is your draft set correctly? This is very important becuase you can be throwing all your heat out the chiminey.
Do you have a cold air return? One of the bestest things I ever did ( and learned about on this forum after a couple weeks of joining).
From what I've read on here, the CT unit will help your burn efficency by maintaining a constant schedule that you regulate through a control unit vs. manual operation. You'll still have to set up your stove and house ( vents etc) for the best operation.
There is a Coal-trol rep on this board who will walk you through....best of luck.
