The insert does have a blower.i leave it on automatic so that it will automatically come on after a certain time and temp has been reached. I have been able toget the stove to 500+ degrees but the thermometer is showing that that's too hot for stove so I try not to get it that high. Will burning at 500 be ok? Also should I split wood up more or leave them how they are already split. Won't that make ten burn faster? How would. I go about an insulated damper block off plate? Why couldn't you just throw some insulation up the chimney? Anything at this point will help
Not sure if the blower control/thermometer you speak of is the same for my stove the Jotul C550, but if it is its not reliable and I do not use it. Instead I leave the blower on all the time and use a regular lamp timer to shut it off.
I think the only difference between your insert and the C550 I have is the size. That thing should be cranking the heat. If you're getting it upwards of 550, then I would try leaving the blower on all the time and use a fan like others have said.
I also must admit, the wood I use is absolutely not the best in the wet/seasoned department too.
Even if your home is poorly insulated that thing should make the room where the stove is prety warm. Then use a cheap box fan to blow cold air from other rooms into the room where the stove is to echange the hot/cold air.
