Rheem water heaters are available at homedepot.com, Amazon, eBay, Craigslist and at rheem.com.au. Both websites have information on gas as well as electric water heaters. Information is also provided on tank-less water heaters and on water heaters for residential use.
The Home Depot website has a store locator that enables anyone to locate the nearest store from where it is possible to buy these water heaters. When a potential buyer enters an address in the search box, the nearest store is displayed on the map with the address of the store. The Rheem website provides information on roof mounted solar water heaters as well. Buyers can enter their postal code and get the address of the nearest store that sells Rheem water heaters.
Listings for used Rheem water heaters on Amazon contain information about the unit, such as its features and functions, pictures of the unit and customer reviews. Each review consists of a quantitative satisfaction rating, in form of one to five stars, and a written account of the customer's experience with the product. While Amazon does not require its users to purchase an item in order to write a review, it does add an "Amazon Verified Purchase" tag to those reviews written by a user who has purchased the item directly through Amazon.
Sites such as Craigslist and eBay do not contain product reviews because each listing is unique to the seller. While eBay does feature a seller rating system, which allows users to provide feedback on a seller after completing a transaction, Craigslist does not because it doesn't require users to create an account in order to post on the site. As such, buyers should exercise caution whenever meeting a Craigslist seller in person.
