Should the glass doors on my woodburning fireplace be open or closed while I have a fire burning?

Question

It's a standard, wood burning fireplace with chimney / flue. I don't understand the purpose of the glass doors.

Answer 1

they need to be OPEN
they are closed in summer and when you have to leave the house IF the fire is not too high other wise you need a screen to stop any stray sparks. It is NOT a gas fire and not meant to look pretty. Over time that glass will shatter from continuous heat absorption if left closed.

Answer 4

Closing the glass doors keeps the fire burning longer and slower. If you have a blower it helps the heat stay in and the blower blows the heat out. Opening the glass doors makes the fire burn faster, and can also cause the sparks to fly out onto your floor so it is also a safety factor. This is for a wood burning stove w/ a blower. If its just a regular fireplace then it doesnt matter as much.but you have to adjust the flue to keep the smoke out.

Answer 5

Closed!
The firebox has another source of air to continue combustion.
The glass doors act like a fire screen would, and keeps the sparks and stuff inside the fireplace. They also act as a heat source to radiate more heat out into the room.
The glass doors also prevent more warm air from the room going up the chimney while the flue is open.

Some older fireplaces have no bottom vent (like mine). Air for combustion is coming mostly from the room (I suppose a little must be from the top of the chimney, but not much). A glass front on the fireplace will still burn, but you won't get much heat from the fire. Closing the damper on the fireplace (when you are not using it) will help stop air drafting from the chimney to your heater intake. Good luck.

Fireplace Doors With Blower

Answer 8

Glass doors 1) are decorative, and 2) keep stray soot from entering your house when there is no fire.

As long as you have a fireplace screen, you can do as you like with the glass doors.

Answer 9

They should be wide open or closed. Not half way. It is your choice. We burn ours with the doors open until we go to bed, then we close them. It is slightly more efficient with the doors closed but not enough to matter.

Answer 10

If you are using it for mood only, open them. For heat, close them as the glass radiates heat and prevents the room air from going out up the chimney. I bought glass doors for my Franklin stove when I found out that 1700 cubic feet per minute of air was going out the chimney. This means it is sucking the heat out of the room.
