Unlike sacrificial magnesium anodes that deplete over time, this system uses patented adaptive technology that continuously adjusts output current to match the local water chemistry. The result is consistent electrochemical protection without periodic anode replacement. A built-in LED fault indicator and audible alarm confirm that the system is operating correctly. The compact control box plugs into a standard 120-volt outlet, keeping the installation straightforward for licensed plumbers and water heater service technicians.\u003c\/p\u003e\n\u003cp\u003eThis powered anode system is suited for residential gas and electric water heaters with tank capacities between 30 and 50 gallons. It is particularly well-suited for softened water applications, where conventional magnesium anodes accelerate sulfur-related odor issues. The system is positioned as a direct replacement part for existing anode installations and is intended for professional installation in residential settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePatented adaptive technology adjusts current output to match water chemistry in real time\u003c\/li\u003e\n  \u003cli\u003eEliminates sulfur odor issues associated with sacrificial magnesium anodes\u003c\/li\u003e\n  \u003cli\u003eBuilt-in LED fault light and audible alarm provide system status confirmation\u003c\/li\u003e\n  \u003cli\u003ePlugs into any standard 120-volt wall outlet for simplified installation\u003c\/li\u003e\n  \u003cli\u003eNo maintenance required after installation\u003c\/li\u003e\n  \u003cli\u003eDesigned for softened water and standard water supply applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement powered anode rod system for residential gas or electric water heaters with 30 to 50 gallon tank capacities.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified water heater technician. Before servicing the water heater, shut off the cold water supply and power or gas to the unit. The hex-end fitting is installed at the anode port using standard plumbing tools. The control box should be secured near the heater and plugged into a grounded 120-volt outlet following local plumbing and electrical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Replacement Part\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tank Size\u003c\/strong\u003e: 30-50 gallons\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Box Input Voltage\u003c\/strong\u003e: 120 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeater Type\u003c\/strong\u003e: Gas or Electric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Setting\u003c\/strong\u003e: Residential\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AO SMITH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100305721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51150473396530,"sku":"100305721","price":207.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305990155.jpg?v=1778612857","url":"https:\/\/voomisupply.com\/products\/ao-smith-100305721-powered-anode-rod-system-water-heater","provider":"Voomi Supply","version":"1.0","type":"link"}
