Unvented Gas Log Set in Vented Chimeny Question
Ok, we had just about given up using the wood burning fireplace that came with the 20 year old home we bought. We simply do not like the smell or mess of wood.
A propane insert would be perfect. Not only would it give the ambience we want but it would throw off heat. Alas it is out of our budget at the current time.
A vented gas log set would be acceptable. No heat but a nice flame. Unfortunately law dictates that the damper must be locked in the open position all the time. When we do this now (with no logset) you can feel cold air coming in the house. Since my recliner is near the fireplace, I do not want a draft on me. Also, it seems foolish, like leaving a window cracked all the time. I could use the vented log set if I knew it were safe to insulate not only the sides of my glass door set but to somehow cover the upper and lower vents as well. In other words try to block the draft out when not using the logset. I am not sure this can be safely done.....thoughts?
That leaves an unvented log set. I know there is controversy here. We had a guy out. He said with our open floor plan moisture should not be a problem. We'd have the flame and heat of an insert for about 1/3 the cost. However, 2 of us have allergies so he reccomended against the unvented logset...though he could not explain why. Personally I think adding mositure to the room is abd idea anyway. Sounds like strike three!
So....could this be done. If I get an *unvented* logset the damper can be left closed all the time thus no draft. To eliminate the moisture / pollution issue, when I turn the logset on, what would happen if I open my damper? Would the logset function? I realize all the heat goes up the chimeney but we just want the ambience of the flame anyway. Could I do this? If I did would all the 'pollution' of the logset go up the chimeiney or would it still go in the room? Also, when the thing is not running I assume there is a pilot light lit...is that throwing mositure into the room too?
If the heatpump ever dies I'd have backup heat as well...even if the water vapor etc came into the room until it was repaired.
