A central location, a tall chimney, and controlled combustion are the keys to a good burn.

Builders are beginning to hear more complaints that traditional masonry fireplaces leak smoke and burn too much wood for too little heat output. The fact is, open site-built masonry fireplaces have always been filthy, smoky, and inefficient, but these drawbacks were less noticeable in drafty, uninsulated houses. Today’s tighter homes, however, are less forgiving, and their occupants are less tolerant.

 

In addition, many modern fireplaces are used strictly as a design element, and many designers have no training in what makes one work. On top of that, many of the masons and other heating contractors who build fireplaces carry over outdated design traditions that are at the root of performance problems.

It doesn’t have to be that way. Building scientists now understand why traditional fireplace designs perform poorly, and masons, manufacturers, and hearth installers have responded with new products and techniques that eliminate past problems.

In this article, I’ll discuss the common causes of fireplace problems, and propose solutions for masonry fireplaces and heaters, as well as less expensive, efficient factory-built wood-burning fireplaces.
