In the middle of winter, fireplaces are a popular topic. This week, Ernie talked about re-building his dual-sided fireplace and adding a damper and tempered-glass doors in the process. In the heating urban myth debate, Elizabeth shared her former roommate's assumption that using a gas fireplace to heat a single room would be more efficient than a central heating system (not necessarily - it depends on your utility rates).
How efficient is your fireplace? Is it gas or wood-burning? Do you have tempered glass doors, an efficient damper, or other devices to keep it from losing heat when you're not using it?
