Quality - As the outdoor wood furnace industry's innovator in the use of stainless steel, HEATMOR™, Inc. can offer the finest in quality and craftsmanship and back it with the best warranty available. The new Models 600 CSS and 800 CSS are constructed with the same 409 grade stainless steel furnaces and have been outperforming mild steel three to one (lasting up to three times longer). To provide the strength and durability in these larger models, we have utilized a heavier gauge of stainless steel (7 gauge) to endure the rigors  of commercial applications.


Features - Years of research and development have gone into the design of all our outdoor wood furnaces and have resulted in a furnace that offers safety and convenience as well as high performance and efficiency. To insure maximum operator safety, we feature a water-cooled firebox door, fully insulated housing and a CSA approved A.R.D. (Anti-Rollout Device) that guards against flashback. Features such as an ash removal auger, bladder system and forced-air draft make the Models 600 and 800 CSS easy and efficient to operate and maintain. The large capacity firebox and firedoor opening allow for large amounts of wood to be loaded with ease. (36"H X 30"W for 600 CSS and 50"H X 56"W for 800 CSS.)

- The need to heat large commercial-type buildings and to utilize waste wood as an energy resource are the reasons for the development of these units. The 800 CSS model is capable of handling the heating needs of any building up to 25,000 sq. ft. (18,000 sq. ft. for the 600 CSS). Convert your waste wood into heat for your business while reducing heating costs and landfill fee for disposal.
