An individual can purchase gas heater parts at both Home Depot and Lowe's, as of 2015. Items such as igniter kits, expansion tanks, recirculating pumps and hoses are all available from the website or from in-store stock.
At Home Depot, buyers can search for gas heater parts by brand, price and rating. They can filter the results by shipment type, and choices include free shipping to the home or local store. Home Depot also lists in-stock items available in a local store where buyers can pick up the parts on the same day. Parts can be compared on the website and user reviews are easy to read.
At Lowe's, buyers can also narrow down search results by rating, price and brand. Products can be compared before buying, and there is a listing of products that are available in the closest Lowe's location. There is a convenient text chat feature as well as available financing for those who need it. Lowe's also features a library of how-to videos, guides and even a video chat that allows a buyer to get real-time assistance from a pro. The search results are sorted by best sellers automatically, but users can also sort results by the lowest price, highest price, brand or rating.
