About Craftmaster Water Heaters
Craftmaster water heaters have served the value segment of the residential water heating market for many years, focusing on straightforward design and affordable pricing. Operating as part of the A.O. Smith Corporation family of brands, Craftmaster leverages manufacturing expertise and quality control processes while maintaining competitive pricing through simplified feature sets. The brand primarily serves cost-conscious consumers, rental property owners, and basic replacement scenarios where budget considerations are paramount. Craftmaster products are distributed through select retailers and wholesalers who cater to value-oriented customers and contractors focused on economical installation solutions.
Craftmaster manufactures traditional tank-type water heaters in both gas and electric configurations, with capacities generally ranging from 30 to 50 gallons to serve typical household hot water needs. Gas models feature conventional atmospheric venting and standard safety controls with either pilot light or electronic ignition systems. Electric units incorporate heating elements and thermostats designed for reliable temperature maintenance. The tanks include glass lining and anode rod corrosion protection following industry-standard construction practices. While Craftmaster water heaters emphasize basic functionality over advanced features or premium efficiency, they meet applicable energy regulations and incorporate the essential components needed for dependable residential hot water delivery.
Craftmaster water heaters come with warranty protection reflective of their market positioning, typically providing 6-year coverage on residential tanks and components. Service support is available through independent plumbing contractors and retail channels where the products are sold. Replacement parts can generally be sourced through appliance parts suppliers and wholesale distributors familiar with A.O. Smith family products. Installation follows standard procedures, and basic documentation provides operating guidance and maintenance recommendations. Craftmaster serial numbers use encoding practices that incorporate manufacturing date information, enabling service technicians to determine unit age when evaluating repair options or advising customers on whether replacement would be more economical for older units nearing end of expected service life.
Where to find the serial
Craftmaster water heaters are built by American Water Heater Company (now A.O. Smith) and sold through plumbing wholesalers. The rating plate is on the upper third of the tank, with the serial labeled SER NO. in a black bordered box.
What the serial actually looks like
Why the age is worth knowing
Craftmaster residential tanks typically come with 6-year tank warranties as the standard, with extended 9-year and 12-year options on premium models. These are workhorse builder-grade tanks that show up in a lot of tract homes - expect 10-12 years of service with basic maintenance, less in hard-water areas.
Quick answers for this brand
Who actually makes Craftmaster water heaters?
American Water Heater Company in Johnson City, Tennessee, which is now a subsidiary of A.O. Smith. Craftmaster has been used as a wholesale-channel brand for decades and the tanks share components with American, U.S. Craftmaster, and Whirlpool-branded units from the same plant.
Is Craftmaster the same as U.S. Craftmaster?
They're closely related but technically distinct brand names used by American Water Heater Company. Craftmaster and U.S. Craftmaster appear on similar tanks in different distribution channels. The serial format and warranty handling are essentially the same for both.
Where can I buy a Craftmaster water heater?
Plumbing wholesale distributors are the primary channel. Craftmaster typically isn't sold at Home Depot or Lowe's, which keeps the pricing competitive for contractors but means homeowners usually get one because a plumber recommended it for replacement.
