Replacement parts for heaters can be ordered from the Sears PartsDirect and Home Depot websites. Amazon.com and eBay also have various heater parts available for purchase. Heater.com is another website that sells replacement heater parts.
Sears PartsDirect lets shoppers type in the exact model number of the appliance that requires a replacement part. This ensures that the part purchased fits the appliance. Sears PartsDirect sells over eight million parts for major brands of appliances. Sears PartsDirect also offers same-day shipping and 365-day returns.
Heater replacement parts can also be ordered through the Home Depot website, although this retailer does not have as wide of a selection as Sears PartsDirect. The Home Depot offers free shipping on select items and on orders over $45, as of 2015. Home Depot also offers free shipping to nearby stores where the replacement part can be picked up. Many of the replacement parts available through the Home Depot website have customer ratings.
eBay and Amazon.com offer free shipping on heater replacement parts for various brands and types of heaters. They also offer competitive pricing, since both list new and used items from small retailers through a marketplace. Both companies also offer priority shipping options.
