Outdoor Wood Furnaces - Boilers - Stoves - Hydronic Heaters

Crown Royal Outdoor Burning Stoves also known as boilers, furnaces or hydronic heaters are one of the least expensive ways to heat in the winter months.

Energy efficient with readily available renewable resources makes it the number one choice for many in cold climates.

Crown Royal Outdoor Burning Stoves are made to be located outdoors near fuel storage, keeping the mess outside. Underground tubing is ran from the stove to the building(s). Virtually any existing heating system can be converted into heating with a Crown Royal Outdoor Burning Stove.

The traditional style Crown Royal Outdoor Burning Stoves are available in four multi fuel models equipped with shaker grates. The shaker grates make it easy to burn multiple fuels such as wood, coal or corn. With capabilities to heat multiple buildings, these four models range from 2,000 square feet to 20,000 square feet.

Also included in the Crown Royal Outdoor Burning Stove line is an EPA Phase 2 Qualified wood burning gasification model. Estimated heating capacity of 8,000 – 10,000 square feet makes this model one of the largest EPA approved stoves on the market today. We also currently have a “high efficiency” model in our lineup with a heating capacity of 4000 – 5000 square feet.

Crown Royal Outdoor Burning Stoves are used in numerous applications such as heating homes, garages, shops, farms, greenhouses, swimming pools, and commercial buildings

The Crown Royal Stoves come in four sizes to ensure a proper fit for your heating needs and will provide hot water for; heating domestic hot water, hot air duct systems, water baseboards, radiant floor heat, unit heaters, hot tubs, pools, greenhouses and other existing hydronic systems.

The Crown Royal Stoves - Outdoor Wood, Coal & Corn Furnaces are a non pressurized system designed to be located virtually next to your firewood storage for convenience and is normally filled once or twice a day, depending on the temperature outside.

We Know The Cold

Our design goal is to give you years of service and to make the unit easy to maintain and operate. We are committed to building the best performing and longest lasting outdoor furnaces on the market, which is why every unit we manufacture is UL 391, UL 726 & CSA B366.1 certified, and comes with a Twenty Year Limited Workmanship Warranty as well as a Twenty Year Limited Corrosion Warranty.
