Making it the number one choice for many consumers, Crown Royal Stoves outdoor coal furnaces, are the most energy efficient and economical way to heat, using readily available renewable resources. Our outdoor furnaces burn 30% - 50% less coal than the competition. 

Designed to be located next to your coal fuel storage for convenience, our outdoor furnaces are a non pressurized system and are normally filled once or twice a day, depending on the temperature outside. Virtually any existing heating system can be converted into heating with Crown Royal Stoves outdoor coal furnace.

The Shaker Grate Series outdoor furnaces are available in two models, all equipped with shaker grates and an ash pan. Shaker grates make it easy to burn coal evenly. With capabilities to heat multiple buildings, these two models range from 4,000 square feet to 10,000 square feet.

The shaker grate and ash pan design were purposefully developed for quick and easy cleaning. The introduction of combustion air under the grates gives a hotter and cleaner burn, while additional air is injected from above the fire, inside the firebox, reducing gases and heat loss up the chimney, producing a cleaner burn that uses less fuel. For the best corrosion resistance and heat transfer possible, our Crown Royal Stoves outdoor furnace firebox and outer drum is a round design constructed out of 409 Titanium Enhanced Stainless Steel.
