No, it is safe to close the door when it is on
no reason to leave door open very safe
Hi John. The actual heating element is located in the slotted metal enclosure under the stove, below the door. Only a small amount of residual heat actually seeps into the area behind the door, so it's perfectly safe to operate with the door closed.
Absolutely. Mine stays closed unless we are turning it on or off
Yes, its designed to operate with the door closed.
The heat comes from under the fireplace. The heater's door is just there for looks.
