Use this chart to learn more about different fuel types—and make the best choice for you.

WOOD PELLET/CORN COAL
BENEFITS Natural and available. Wood can supplement furnace usage and reduce heating costs up to 30%. Clean-burning and consistent. Pellets are affordable, available and renewable. Coal can burn up to 24 hours without refueling. And, it costs about 30% less than purchased wood.
FIRE CHARACTERISTICS Expect robust, steady fires. Harman wood products deliver even heat, long burns and high-efficiency. Active and robust. A small fire can burn an inch high, while a powerful 10-inch blaze is bright and intense. Coal fires are strong and steady. They're generally more subdued, providing clean blue flames and a stunning glow.
FIRE STARTING Paper, kindling and fire-starting logs are effective. Automatic thermostats and temperature controls do the work for you—just keep your hopper filled. Coal fires start slowly. Begin with paper and dry kindling, then add coal in batches.
TYPE OF HEAT Adding more fuel will immediately increase convective heat. Radiant heat will remain steady. Most of the heat is convectional—blown through a heat exchanger and out into the home. Coal is generally hotter than wood and has a longer, more sustainable burn for impressive radiant heat.
FUEL STORAGE & HANDLING Dry storage is important. A cord of wood is stacked 4'x4'x8'. On average, a 1,500 sq. ft. home will require 2-4 cords per season. Pellets are normally available in 40 lb. bags. A 1,500 sq. ft. home will use 2-4 tons per season, on average. Dry storage is important. And, a 4'x4'x8' stack of coal should supply the average home for one season.
