Used oil furnaces can be sold online through auction sites such as eBay, as well as through specialty used furnace classifieds sites such as Access Used Furnaces. Local classifieds sites such as Craigslist are also frequently used to sell used oil furnaces.
When selling an item on eBay, users must sign up for a free seller's account. This allows the user access to the eBay virtual storefront tools, as well as its seller feedback system. In this system, any user who purchases an item from the seller is given the option to rate the experience and write a review of the transaction. A seller's rating is important for building a high level of trust amongst site users. Sellers have the ability to include pictures in each listing, as well as choose from either an auction sale model or an immediate purchase sale option.
