Outdoor wood burners and furnaces can be purchased online through specialized equipment retailers such as Northern Tool + Equipment, from auction sites such as eBay, and through local classifieds sites such as Craigslist. Some manufacturers, such as WoodMaster, allow users to find local distributors through their websites.
Listings on the Northern Tool + Equipment website include a picture of the wood-burning furnace being sold, detailed information about its function and available features, customer reviews, and a question and answer section. The question and answer portion of the listing allows a user to pose any questions that she has about the product to the site's community in order to obtain as much information about the product as possible. Questions typically cover topics such as requirements for installation or the types of wood that a furnace can burn. Users can also compare different listings within the site to see the differences between products.
Craigslist allows users to create free listings for wood burners as well as other products through its site without signing up for an account. As a result, there is no way for users to track the history of different sellers. As such, Craigslist advises users to exercise caution when meeting sellers and warns against sending funds electronically before receiving any products.
