Crown Royal Stoves - The Benefits

Opposed to other wood burning appliances, Crown Royal Stoves - Outdoor Wood Furnaces, offers greater benefits.

Multi Fuel Outdoor Furnaces
With Crown Royal Stoves you are able to burn Coal, Cob Corn, Cherry Pits, Wheat, Barley, Wood and many other natural renewable fuels.

Safety:
An outdoor furnace helps eliminates the risk of a house fire, chimney fire, indoor smoke, or carbon monoxide poisoning. Each Crown Royal Stove has been rigorously tested and is UL & CSA certified.

Cost Savings:
Crown Royal Stove - Outdoor Wood, Coal, Corn Furnace owners can save approximately 50% - 100% of their annual heating costs. Reduce or even eliminate hot water bills and the dependence on foreign fuels.

Convenience:
Depending on the outdoor tempurature and size of the unit, our outdoor furnaces only need to be loaded once or twice a day. Eliminate dirt, bark, ash, smoke, soot, or insects from inside your home. It now stays outside where it belongs.
If you need to remove copious amounts of snow and ice every winter radiant piping may be installed under your driveway or walkways to melt it away.

Even Heating:
As opposed to an indoor wood stove or fireplace, our outdoor furnaces are thermostatically controlled, this offers a even heat throughout your home or business.

Class A Insulated Stainless Steel Chimney
For ease of extending your chimney to meet HPBA Safe Burn Practice standards.

Extra Large Ash Pan Door
This allows you to have extra room for ash removal.

Turbo Draft System
Allows for a cleaner more efficient burn inside the firebox and allows secondary gases to be burned before escaping out the furnace chimney.

How Outdoor Wood, Coal & Corn Furnaces Work

As the price of fuel oil rises to new national record highs, more homeowners and businesses across North America are looking to alternative methods for heat. Crown Royal Stoves - Outdoor Furnaces, can dramatically lower your heating bill by allowing you to burn coal or natural renewable fuels such as wood or corn.

Unlike indoor wood burning furnaces / stoves, Crown Royal Stoves - Outdoor Wood, Coal & Corn Furnaces, leaves no smoke or waste in the house and keeps all the mess and bugs where they belong, outside.

furnace stove secondary burn system

SECONDARY BURN SYSTEM ( TURBO DRAFT SYSTEM ™)

The exclusive Turbo Draft System ™ was designed into our outdoor furnaces to force fresh air over the open flames. By forcing the gases down to the fire below they are reintroduced into the burning fuel thus giving a hotter combustion and a cleaner burn. This means less heat is lost by escaping into the furnace chimney network.

With our original shaker grate and ash pan design, fresh air is introduced under the fire feeding it oxygen as needed. When the damper is opened oxygen is introduced into the furnace ash pan system to feed the burning coal, corn or wood allowing the fuel to burn hotter and cleaner.
(Forced air and oxygen introduction in furnace is shown in blue on left image.)

outdoor furnace stove water jacket

ROUND DESIGN & WATER TRANSFER TUBES

The Crown Royal Stoves consists of a round firebox surrounded by a round water reservoir, also known as a water jacket. The combustion of wood, coal or corn heats the water in the surrounding water jacket, which is pumped via insulated underground pipes into your home or buildings.
A round firebox and water jacket design means there are less weld points which reduces the amount of stress on the steel to ensure there is less cracking. The round water jacket design allows more water to be heated efficiently due to the fact that more water is touching the heated firebox surface.

Water transfer tubes are designed into the Crown Royal Stoves, situated directly over the fire to allow even more water to be heated. As the fire burns, water flows through the transfer tubes giving an even distribution of heat in the water jacket. This design feature eliminates hot and cold spots in the furnaces water supply.

outdoor wood furnace stove circulating pump

OUTDOOR FURNACE CIRCULATION & HEAT TRANSFER

A four inch (4") gap separates the back of the firebox and the water jacket allowing the supply and return lines, located at opposite corners on the back of the furnace's water jacket, to create a strong enough circulation, forcing the water over and around the firebox to transfer as much heat as possible.

With the use of insulated underground pipes, hot water is moved from the outdoor wood furnace to your home or buildings, with the use of a circulating pump. The circulating pump is usually hooked to the hot water supply line, located on the bottom connection on the opposite side of the return line. This ensures that the water being used to heat your home or buildings does not have any cold spots.
