When should you close the fireplace doors?

Answered by Tom Adger

When it comes to closing the fireplace doors, there are a few important factors to consider. First and foremost, it is crucial to understand that the doors should always be fully open or fully closed. There is no in-between when it comes to the position of the doors.

Now, let’s talk about glass doors specifically. Glass doors can be a great addition to a fireplace, as they provide an extra layer of safety by preventing sparks and embers from escaping into the room. However, when it comes to using the fireplace, the glass doors should be fully open.

When starting a fire, it is important to have the glass doors fully open. This allows for proper ventilation and ensures that the fire receives an adequate amount of oxygen to burn efficiently. By having the doors open, you allow the air from the room to freely flow into the fireplace and fuel the flames.

Once the fire is burning strongly, you may still keep the glass doors fully open. This allows for a better view of the fire and creates a warm and inviting atmosphere in the room. Additionally, keeping the doors open at this stage ensures that the fire continues to receive an ample supply of oxygen, which promotes a clean and efficient burn.

However, as the fire starts to die down and you no longer require the full heat output, it is recommended to close the glass doors. Closing the doors helps to minimize the amount of room air that is drawn up the chimney. This can be especially beneficial during colder months when you want to retain more heat in the room rather than losing it up the chimney.

By closing the glass doors, you create a barrier that prevents the warm air from escaping through the chimney. This can help to maintain a comfortable temperature in the room and ensure that the fire’s heat is effectively utilized.

Glass doors should be fully open when starting a fire and when the fire is burning strongly. This allows for proper ventilation and ensures an efficient burn. As the fire dies down, closing the glass doors can help to minimize heat loss and retain warmth in the room. Remember, the doors should always be fully open or fully closed to ensure safety and efficiency.
