Can't find ANY information about my new stove

    Good Morning....I am hoping for help from wood stove experts.
    We had the opportunity to buy a wood stove that is from Sweden and looks brand new. It isn't your typical wood stove, my research seems to show that it might be a wood furnace. It is from 1979 but looks like it might have been used 2 or 3 times. You can see it was built when things were still built right. Our concerns are we know nothing about it. How many btu's does it put out, there doesn't seem to be a flue to operate, so all the heat would seem to be escaping. When you put your head in the stove and look up, there are 3 cylinders going up. Seems to be a storage chamber above stove. In 10+ hours researching online I have found very very minimal information other than the company closed (or now does geothermal heat in Sweden thanks to my Uncle in Germany....so I have really tried exhausting all avenues to find out about this stove). I found a patent on the stove and trademark of the term combi-therm (yet no explanation of what combi-therm means.....so to us it seems that the blower regulates the circulation of heat, so it radiates and circulates the heat). I have several pictures to hopefully help.
    Any and all help is appreciated. As you will see the vent is on top but it has a vent within a vent (it looks like). It seems like it will be ultra efficient if we can find out how to use it.
    Thank you for your time :)

    Are those doors air tight? Is there glass behind that screen or is it like an open fireplace? I don't think I would recommend installing something like that. With an older wood stove, you have a generally straight forward design that is easy to operate and unstall. That thing looks like and experimental design or something.

    Anja,
    Without looking at the unit, I believe it's a direct vented burner designed to not use any oxygen from the inside of the building.
    Looks like the same air intake principal as a direct vent gas heater;

    You need to see if the center pipe going up out of the firebox is the exhaust flue (the inner of the outlet on top) and if the other two above the firebox are connected to the space between the inner and outer pipes on top. These would be the intake, called a "direct vent" so after starting the fire with inner doors open, using inside air to get it drafting, you then close the inner doors so it has to pull it's intake air down the outside of the inner exhaust pipe. (The double pipe is extened all the way to the top of chimney) This intake air cools the outside pipe, and the exhaust pipe preheats the incoming air to the fire)
    "Combi" probably refers to combination fireplace in open door with screen mode / radiant heater in closed mode.

    Homes over there are sealed much tighter and require their own air intake.
    If you look at an Empire Direct Vent intake / exhaust vent, you'll get the idea of the chimney pipe and cap that has the integrated intake pipe around the inner exhaust pipe.

    If you look into websites for Scandinavian built log homes, you'll find this type of heater. They are up around the Artic Circle and know their heat !
