Electric-powered anode systems for large, glass-lined storage tanks are available. The nonconsumable titanium anodes balance the tank without the need for replacement anodes, whether retrofit or new installation. The maintenance-free powered anode system can serve tanks up to 850 gallons while eliminating the need to take the hydronic system offline periodically to replace consumable anodes. Hassle, maintenance costs, and rotten egg smell are avoided for the lifetime of the system, the company said. The titanium rods are connected to a small, wall-mounted power unit placed within 10 feet of the tank. The easily connected unit uses a standard 120-V power outlet. The anodes have one low-voltage wire and a ground wire, which is attached to the tank. The system also offers a visual alert; if the system detects a fault in the wiring, the power source will flash with a green and red LED.
