Warnock Hersey is not the brand name of a wood stove manufacturer, but rather a product safety and performance verification mark which appears on nearly 80% of all wood stove doors in North America. The WH Mark is issued by the third-party certification agency Intertek.
The Warnock Hersey Mark guarantees that a product has been tested by Intertek and found to comply with all relevant safety standards and codes, particularly in reference to fire safety. The letter C on the bottom left side of the Mark indicates that the door complies with Canadian safety standards, while a US on the bottom right verifies that the door meets standards in the United States. The WH Mark often appears on a plaque or sticker on the back or side of the stove along with the specific testing standards used, as well as safety and setup information. This makes it simple to verify that a particular stove is Warnock Hersey-certified.
Major hardware stores such as Home Depot and Lowe’s carry wood stoves for purchase online, either for delivery or in-store pickup. Other large specialty stores such as Rocky Mountain Stove & Fireplace in Denver have large online catalogs of stoves available for delivery. In larger towns, stores that sell spas and high-end outdoor grills often have wood stoves as well.
