Thermoheat heaters can be purchased through home improvement stores such as Lowe's, home goods stores such as Sam's Club and online mass retailers such as Amazon. Internet auction sites such as eBay also frequently contain listings for Thermoheat heaters, though selection and availability may vary.
Each listing on the Lowe's website contains a picture of the item along with a detailed description of its features and specifications. Listings also feature both customer reviews and a question and answer section. Each review consists of a star rating and a written account of the customer's experience with the product, while the question and answer area serves as an open forum for site users to ask each other questions about the product prior to making a purchase. Users have the option to choose from a variety of deliver methods for each item, including in-store pickup and Lowe's truck delivery.
Amazon also features a question and answer section for all of its products, along with product descriptions and user reviews. Each listing on the site also displays related products based on the activity of other members who also viewed that product, allowing users to purchase related accessories that other users have frequently purchased in conjunction with that item.
