Energy King 365EK Indoor Wood/Coal Furnace The ENERGY KING 365EK Wood/Coal Furnace can heat up to about 1,500 square feet. In addition to square footage, some of the factors that may affect your heating needs are your home's age, design, and geographic location (climate). Other factors to consider are your chimney's draft strength and whether you plan to burn wood or coal as your primary fuel source. It is important to choose a solid-fuel heating appliance that is correctly sized for your home. An undersized wood or coal furnace will need to be fired more often, while an oversized wood or coal furnace will be less efficient and could contribute to dangerous creosote buildup.
