Gel fuel heaters can be purchased online or in-store from home improvement and supply stores such as The Home Depot and Lowe's, as well as from specialty heating and cooling retailers such as Air & Water. Internet auction sites such as eBay also feature listings for gel fuel heaters.
The Home Depot allows users looking for gel fuel heaters to browse all available models directly through its website. Listings can be sorted by several different factors, including manufacturer, price range and customer rating. Home Depot does not require its users to verify purchase of a particular model or unit in order to write a review. Each review consists of a star ranking ranging from one to five and a written account of the customer's experience with the model. Users can also use the website to check if a nearby store currently carries a specific model of gel fuel heater, as well as arrange to have that item held at the store for pick up rather than have it shipped.
EBay allows its users to sell items either through an auction format or through a standard immediate purchase format. With the auction model, sellers set an initial price and a bidding duration, at the end of which the user with the highest bid wins the item.
