The powered anode for water heater is made of titanium substrate and coated with mixed metal oxid. It is a long-term solution to preventing sulfide smells (that rotten egg smell) produced by well water. This non-consumable powered titanium anode rod provide a controlled release of electrons that negatively charge the water heater or water tank and its components, preventing corrosion (rusting) from occurring.
Extends life of water heater tank 20-year
Permanently eliminates rotten egg smell in water
Replaces water heater (20-100 gal) tank's existing hex head anode rod only
Powered anode tod protects the tank interior from top to bottom
Water softener use does not affect the longevity or protection
Threading: G 3/4", 3/4" or customize;
Rod diameter: 2mm, 3mm or customize;
Rod length: 340mm or customize;
Coating area: customize;
Size: 20-100 Gallon Tank.
A powered anode relies on electricity being fed into the anode to impose a flow of current rather than relying on natural electrolysis. If the powered anode is made from the right material and it remains powered, the anode protects the other metal (steel water heater tank) for many years. It even lasts longer than a standard anode rod. The powered anode does not react with the water at all, but prevents any smelly water. Also, in some water conditions the standard magnesium anode rod reacts with the water. This can create an unpleasant rotten-eggs smell/taste to the water. A powered rod will prevent this reaction.
To adapt this powered anode, a 3/4" brass tee and a 3/4" plastic-lined nipple of sufficient length to extend past the thickness of insulation will be required.
Most gas heaters will require a 3" or 6" long nipple.
May require a longer nipple and brass coupler to clear the insulation and complete the install.
plumbers tape, metal antioxidant, and a screwdriver or box cutter to clear away insulation are required.
Q: Does it get used up?
A:Powered anode rods are impressed-current anodes are not consumed during use. As they are not "sacrificial", They feed a very small amount of electricity into the tank to replace that produced by sacrificial anodes. The electrode is made of titanium. Interestingly, while sacrificial anodes are consumed more rapidly in softened water, powered anodes actually work less hard because higher conductivity makes it easier for electricity to flow between anode and cathode (tank steel).
For now, specifically, I warn you off using this in stainless steel tanks and multi-anode indirect-fired heaters. The powered anode is set to protect a small amount of exposed steel in a glass-lined water heater, not the vast expanse of a stainless tank. The latter two have complicated internal architectures that may prevent a powered anode from protecting all parts of the tank.
Q: Will it void the warranty of my water heater?
A:The powered anode works very well to protect a heater in softened water and without causing odor. People who have odor in that environment have limited choices. One is to remove the factory anode, but that must shorten the life of the heater. This is commonly recommended by people who service softeners without regard for the heater's warranty.
People without odor but who use a softener often see their heaters rust out every couple of years. One recent case was three 75-gallon heaters in seven years. Employing a powered anode solves both issues and in a way that actually helps the manufacturers by cutting their warranty costs.
