About State Water Heaters
State water heaters have served American homes and businesses for over 70 years, building a reputation for straightforward design, reliable performance, and excellent value. Founded in 1946 in Ashland City, Tennessee, State Industries quickly became a respected manufacturer through focus on quality construction and customer service. The company operates as part of A.O. Smith Corporation while maintaining its distinct brand identity and product lines. State products are sold primarily through wholesale distributors to professional plumbers and contractors, ensuring proper installation and service support. Their extensive commercial product range makes State a preferred choice for apartments, hotels, restaurants, and industrial facilities.
State manufactures a comprehensive range of tank-type gas and electric water heaters for both residential and commercial applications, with capacities from compact 2.5-gallon point-of-use units to massive 120-gallon commercial systems. Residential models feature reliable gas valve assemblies, quality heating elements, and Everkleen self-cleaning technology that reduces sediment accumulation. The Proline XE series delivers enhanced efficiency through improved insulation and combustion design, while commercial Sandblaster models include heavy-duty construction with commercial-grade anodes and reinforced tank designs. Many units achieve impressive first-hour ratings and recovery rates to meet high-demand scenarios in busy households or commercial settings.
State supports its products with competitive warranty terms including 6 to 12-year coverage options depending on the model and installation requirements. Professional contractors appreciate State's consistent quality, straightforward installation procedures, and readily available replacement parts through wholesale suppliers. The company provides detailed specification sheets, installation manuals, and sizing calculators that help ensure proper equipment selection. Technical support is available through distributor partners and State's customer service team. State water heater serial numbers typically incorporate clear year and month indicators, making it easy for service technicians to determine manufacturing dates when planning maintenance or evaluating replacement timing.
