Warranty Logo

The Heatmor residential models are capable of burning certified types of coal. By adding the Shaker Grate Option to your Heatmor Outdoor Furnace, you will easily be able to burn coal as well as cord wood in the same unit. For more information, please contact the Sackstore. 
Most warranties, no matter how many years of coverage they provide, are only good as long as certain "conditions" or maintenance procedures are adhered to. HEATMOR provides you with an "unconditional" warranty on defects in materials and workmanship as well as corrosion. As long as you operate your furnace in accordance with the safety guide lines set forth in the owners manual, your limited lifetime warranty is intact.
HEATMOR uses stainless steel in the construction of their outdoor wood furnaces because it is proven to last up to 3 times longer than mild steel no matter what the gauge is. HEATMOR pioneered the use of 409 Stainless Steel in outdoor furnaces in 1988 and has set the standard for the industry ever since.  
The HEATMOR over/under forced air draft makes our furnace more combustion efficient therefore, it produces a very fine ash. Approximately 5-8 gallons of these ashes can be safely and conveniently emptied out the rear of the furnace every 2-3 weeks. (Note: Use a noncombustible container for ash storage.)
