About American Water Heaters
American Water Heater Company has provided reliable water heating solutions since 1930, building a reputation for quality manufacturing and dependable performance across residential and commercial markets. Operating as part of A.O. Smith Corporation, American maintains its brand identity while benefiting from advanced engineering resources and manufacturing capabilities. The company focuses on delivering value-oriented products that meet essential performance requirements without unnecessary complexity or premium pricing. American water heaters are distributed through professional wholesale channels to contractors and plumbers who appreciate straightforward installation, readily available parts, and consistent product quality for their customers.
American manufactures both gas and electric tank-type water heaters with capacities ranging from 30 to 100 gallons for residential use, plus larger commercial models for apartments, offices, and light commercial applications. The Proline series represents their core residential offering with features including self-diagnostic gas valves, quality tank construction with vitreous enamel coating, and magnesium anode rods for corrosion protection. Power-vented models accommodate installations where standard atmospheric venting is not feasible. Commercial units incorporate heavy-duty components designed for continuous operation and high-demand scenarios. While American emphasizes practical functionality over premium features, their products meet industry efficiency standards and provide reliable hot water delivery for everyday household needs.
American Water Heater Company backs its products with standard warranty protection typically covering 6 years on residential tank models, with terms clearly outlined in product documentation. The extensive wholesale distributor network ensures ready availability of replacement parts and service support through local plumbing professionals. Installation manuals provide clear instructions for proper setup and code compliance. Technical support is available through distributor partners and the company's customer service resources. American water heater serial numbers follow straightforward formatting conventions that typically indicate manufacturing year and month, allowing service technicians to quickly determine unit age when evaluating maintenance needs or planning replacements for aging equipment.
