GreenTech Manufacturing inc. proudly presents Crown Royal Stoves - Outdoor Wood, Coal & Corn Furnaces. Our line of outdoor wood furnaces are able to burn wood, coal & corn and are constructed out of 10 gauge 409 AL Titanium enhanced stainless steel for the best corrosion resistance and heat transfer possible. Made to withstand the roughest climates, the Crown Royal Stoves are one of the most efficient ways to heat your premises.

Based out of International Falls, Minnesota, which is known as "The icebox of the nation", our temperatures plummet as low as -40°F during the winter season. This allows us to test and develop the Crown Royal Stoves properly and make improvements where we see fit. 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.

Crown Royal Stoves - EPA Testing
Early in January 2007, the U.S. Environmental Protection Agency (EPA) initiated a voluntary program for manufacturers of outdoor wood furnaces. The EPA's primary intent is to encourage manufacturers to produce cleaner Outdoor Wood-fired Hydronic Heaters (OWHH) models. The EPA also wants those who buy an OWHH to buy the cleanest models available, which are those that meet EPA performance verified levels. To participate in this program, manufacturers commit their best efforts to develop cleaner models with goals of distributing their units starting in April 2007.

Because of this program we signed a partnership agreement with the EPA to promote the manufacture and sale of cleaner outdoor furnaces. GreenTech Manufacturing is working closely with EPA accredited laboratory, Intertek Testing Services NA Inc, to ensure all our furnaces meet and pass the new testing guidelines under Phase I of the EPA OWHH Program.
