State Water Heater: Complete Technical Guide, Installation, and Cost Analysis
A State water heater is a residential or commercial water heating system manufactured by State Water Heaters, featuring gas, electric, heat pump, and tankless models with 6-12 year warranties. These units range from 30-100 gallon capacities and achieve energy factors between 0.67-3.45 depending on fuel type and technology. This guide covers every State model type, sizing calculations, installation requirements, maintenance schedules, and replacement costs for homeowners and contractors.
What Is a State Water Heater and How Does It Work?
A State water heater is a branded water heating appliance manufactured by State Water Heaters, a subsidiary of AO Smith Corporation, producing residential and commercial units since 1946. These systems heat domestic water through gas combustion, electric resistance elements, or heat pump technology, storing hot water in insulated tanks or providing on-demand heating through tankless designs. State water heaters feature proprietary technologies like the EcoNet smart monitoring system, self-cleaning dip tubes, and Blue Diamond glass coating for enhanced durability.
State water heaters operate through three primary mechanisms depending on fuel type. Gas models use atmospheric or power-vented burners ranging from 30,000-75,000 BTU input, heating water through combustion chambers with spiral heat exchangers for maximum efficiency. Electric models utilize dual 4500-watt copper heating elements with thermostatic controls maintaining temperatures between 90-150°F. Heat pump models extract ambient heat using refrigerant systems achieving 2.0-3.45 energy factors, while tankless units heat water instantaneously through copper heat exchangers at 140,000-199,000 BTU input.
Which State Water Heater Types Are Available for Residential Use?
State manufactures six distinct water heater categories for residential applications, each optimized for specific household needs and fuel availability. Gas storage models include the ProLine series with 30-50 gallon capacities featuring atmospheric venting, the ProLine XE power direct vent series for sealed combustion applications, and high-efficiency condensing models achieving 0.80+ energy factors. Electric options encompass standard ProLine units, ProLine XE hybrid heat pump models reducing energy consumption by 73%, and compact point-of-use heaters for remote installations.
Tankless State water heaters provide endless hot water through natural gas or propane models delivering 6.5-11 gallons per minute flow rates. The ProLine XE condensing tankless series features 199,000 BTU maximum input with 0.96 energy factors and built-in recirculation pumps. Solar-compatible models integrate with thermal collector systems, while commercial-grade residential units offer 75-100 gallon capacities for large households. Each type carries specific venting requirements, electrical needs, and space considerations affecting installation complexity and total project costs.
How Do You Properly Size a State Water Heater?
Proper State water heater sizing requires calculating household peak demand using the First Hour Rating (FHR) method combined with simultaneous fixture usage analysis. A family of four typically requires 60-80 gallons FHR for gas models or 50-65 gallons for electric units, based on three bathrooms, kitchen usage, and laundry demands. Calculate total demand by adding fixture flow rates: showerheads use 2.5 GPM, washing machines 3.0 GPM, dishwashers 1.5 GPM, while considering usage patterns like morning routines where multiple fixtures operate simultaneously.
Tankless State water heaters require different sizing calculations based on temperature rise and flow rate demands. Determine incoming groundwater temperature (ranging from 35°F in northern climates to 75°F in southern regions), subtract from desired output temperature (typically 120°F), then multiply by total fixture flow rates. A State 199,000 BTU tankless unit provides 9.5 GPM at 35°F rise but only 5.5 GPM at 65°F rise, making climate-specific sizing critical. Oversizing by 20% accommodates seasonal variations and ensures adequate performance during peak demand periods.
