We've tested on two alaska stoves. Actually they were the first two we tested on and they've been running a Coal-Trol system in some form for the last three years. We've also had a number of customers install on alaska stoves since we started selling to the general public last year.
You can install any of the four systems we have on our web site, but for that stove I'd recommend a Basic or Basic+ system (the difference between them being the type of thermostat included in the system, which is personal preference based on your needs).
There are three possible reasons you might want the Standard or Standard+ systems:
1) You intend to get the ignition system at some future date and want to save money by getting the control module with the igniter outlet built into it. We haven't set the prices for the ignition system and the CM2 (Basic) upgrade that will be needed as of yet, but figure buying the CM1 based system (Standard/Standard+) will end up saving you in the neighborhood of $100.
2) You wish to have the coal-trol digitial thermostat be able to turn a forced air furnace fan on/off as needed. This is more typically found in coal furnace installations and would require the purchase of the Standard+ system with the optional fan control contacts. To purchase this we require the customer call us so we can make sure it is what they need.
3) You desire the additional power vent and limit switch features of the CM1 based systems. The Basic and Basic+ (CM2 based) systems work fine with power vents and direct vents, but the CM1 can eliminate some intermediate wiring and provide a cleaner looking installation. To be clear though: The Coal-Trol Basic and Basic+ systems are completely compatible with power vent and direct vent stoves.
Lastly, the 11% figure is based on analysis of the way a traditional on/off thermostat and the way the Coal-Trol Digital thermostat work to control the heat output of the stove. It has been backed up by customer experiences and our own testing on various types of stoves, including the Alaska models. The claim is independent of the particular stove since it is based on the control methods and algorithms we use.
Hope that helps. If you have any more questions feel free to ask.
