Advances in fireplace design and technology have made today’s wood-burning stoves more efficient than ever. Today’s fireplaces burn fuel more evenly, circulate heat more evenly, and are designed to prevent ambient heat loss. One of the main reasons for this shift is improvements in how well fireplaces can deliver natural convection heat transfer. How does natural convection relate to home heating? Convection refers to the process of cycling warm air through your home. A convection-style wood-fired heater – like our best-selling FALUN – creates warm air in the firebox, which is forced to rise and pushed out into the interior space. This process creates a natural vacuum that pulls cooler air from throughout your home into the firebox, where it’s warmed, and circulated back into the home.
