Also known as outdoor boilers, outdoor furnaces or hydronic heaters, Crown Royal Stoves Multi Pass outdoor furnaces are a non pressurized system, designed to be located next to your fuel storage for convenience, and are normally filled once or twice a day, depending on the temperature outside.
The shaker grate and ash pan design was purposefully designed 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.
The outdoor furnace Multi Pass Series is manufactured with triple pass heat exchangers and water filled heat exchanger tubes that produce the highest efficiencies of a conventional outdoor furnace; the bottom line is you will burn 30% - 50% LESS THAN THE COMPETITION. In addition to these features, it is equipped with a turbo draft fan that produces secondary combustion along with shaker grates and a removable ash pan for quick and easy cleaning. For the best corrosion resistance and heat transfer possible, our Crown Royal Stove outdoor furnaces firebox and outer drum is a round design constructed out of 409 Titanium Enhanced Stainless Steel.
Virtually any existing heating system can be converted into heating with a Crown Royal Stove outdoor furnace. The Multi Pass Series is available in two models. These two models range from 6,000 square feet to 10,000 square feet.
