    Default Wood fire won't stay alight overnight

    Hey all,

    Wondering if anyone might be able to chime in any thoughts - somewhat recently moved into a home that has a Heatcharm C600 woodheater, and for the life of me I cannot get it to hold a fire overnight. If I have a hot fire going, load with hardwood and shut it down (close the damper handle), come morning there will only be ashes left, no embers. Large pieces of wood will be burnt down to near nothing, and coals won't retain much heat.
    My previous experience with a similar fireplace (also a Heatcharm) was if loaded at night and shut down, all that is need in the morning is to open the damper, throw in some fresh wood & off it goes. At the moment I'm having to relight the fire each day which is a pain in the plums.

    The top baffle plate is in good order, it has fire bricks + with cast iron plates on the sides, and I recently made & replaced the secondary air tube.
    Burns well when its running, but doesn't seem to shut down & hold heat overnight.
    Any thoughts?

    The air intake regulator is not closing far enough for the fire to slow down and last overnight.
    You also need to watch what kind of firewood you are using.

    Probably a air intake or damper leak.

    Getting to much air, something is not sealing as it should.

    Could be the door seal too.

    Door seal is usually the first to wear out but luckily also the cheapest part to replace.

    My 15yr old heater started with this issue at the end of last winter. This year I gave it a birthday, paint, new glass (WOW $180) and seals, new door seals for the ash door and the main door, and adjusted the latch to seal better. Now quite happily just ticks over for up to 10 hours...
    And.....your point is.....what exactly?

    Cheers all for the replies - I was going with the assumption that no smoke without fire, no fire without air.
    The primary damper flap seals, cant see anything leaking there.
    I've adjusted the door latch, as the pin it latches to was a little worn in one spot.
    The previous owner looks to have replaced the rope seals not all that long ago by the state of the rope - it appears to have the indentation of the door frame in the rope all the way around, but maybe there is a spot where it isn't quite sealed? I tried running a flame around the door when closed, to see if showed any sign of airleak, but could notice any.

    Its a rather larger fire box, would there be any chance it could draw too much air down the chimney even when closed down? Or would there be somewhat of a vacuum effect when properly shut down?
