Powered Anode Rod
While anode rods themselves may be a office of the H2O heater that not all homeowners understand, powered anode rods can live fifty-fifty more difficult to comprehend. Despite their seemingly complex nature, they tin can live a major asset to the workings of your water heater in addition to the grade of maintenance required.
Before investing in a powered anode rod, the curious consumer should starting time understand its anatomy, how as well as how well they go, how long it lasts, etc. We take answers to all the important powered anode rod questions yous accept.
On average, powered anode rods toll $170, final xv years, together with role minimal ability. They emit electrical currents that stop tank corrosion without the need to corrode themselves. Reviews support their effectiveness. They tin can live used in all water types. Corro-Protec is a notable make of adept powered anode rods.
How Do Powered Anode Rods Work?
Anode Rod Anatomy
In society to fully empathize how powered anode rods operate, y'all must start understand their anatomy.
The sparse metallic rod visible at the bottom of the device is titanium. This is connected to a wider steel part, which does non sit in the water only rather has a threaded surface, which allows it to be screwed into the anode port of the H2O heater tank.
Atop this stainless steel body is a hex head, which is what your tightening/untightening tools will bag onto during installation as well as removal. Attached to this is the concluding. This is what allows the anode to live powered.
A wire joins the rod’s concluding to an electric command module (current rectifier), which is plugged into the wall socket in addition to supplies the rod alongside an electrical electric current.
Anode Rod Operation
The footing of the performance of powered anode rods is that they liberate a minor electrical electric current into the tank. This protects the H2O heater tank from corrosion patch allowing the anode rod itself to stay intact, different sacrificial anode rods that corrode over time.
Fundamentally, corrosion is an exchange of electrons with oxygen-containing molecules. The cloth losing electrons oxidizes (corrodes).
In the presence of H2O together with air, reactive metals, like the steel of your water heater tank, lose electrons naturally. However, the electrical electric current from the powered anode rod stops this loss. Furthermore, the pulses aid to forbid private corrosive elements from being inwards contact with the tank long enough to react.
The pulses too end minerals like calcium from edifice upwardly on the tank and causing harm. This is the reason why powered anode rods are groovy for role in homes supplied past difficult (mineral-rich) H2O.
Powered anode rods as well can conform to whatever type of water they are placed in.
If you lot are interested in reading about this mechanism in more item, I have a whole article dedicated to how powered anode rods operate, which you should detect helpful.
Powered Anode Rods Aren’t Shock Risks
With all this mouth of current together with electricity in a H2O storage tank, it is valid to live concerned that powered anode rods are a health together with safe chance.
Although it is truthful that anode rods post an electric current into water, ane of the nearly well-known conductors of electricity, they do not take health risks associated with electric daze. This is because the electric current generated is far too small-scale to electrocute someone if they were to come up inwards contact alongside it.
Despite this low amount of electric current, though, it is of import to brand certain that the proper precautions are met when doing maintenance or installation, including cut off ability to the outlet into which the anode rod is plugged too the outlet supplying the water heater (if it is an electrical model).
Do Powered Anode Rods Really Work?
The engineering science of the powered anode rod sounds wondrous too far better than sacrificial anode rods. Although it may seem like a miracle product, it is important to investigate whether the powered anode rod really does what it says it will make.
I’1000 always really skeptical when it comes to the claims a manufacturer makes. Their interest is firmly rooted in selling their production. Yes, they want it to run then that they can brand their customers happy, ensure repeat clientele, too contribute to social club’sec technical advancement, just the bottom business is the height priority.
So, in order to make up one's mind if a device similar this industrial plant, yous have to expect at three things:
- The scientific discipline behind the device.
- The results of scientific studies into the device’sec effectiveness.
- The reviews of customers who accept purchased and used the device.
The Science
We’ve already looked at the scientific discipline behind powered anode rods. In my opinion, it’s pretty audio, but you tin brand up your own mind inwards this regard.
Research-Based Confirmation
I cannot detect whatever official scientific studies that enquiry the effectiveness of powered anode rods. This doesn’t really surprise me. If every new appliance released onto the marketplace was starting time subjected to rigorous scientific report, nosotros would live without many of today’second mod conveniences, the blueprints of which would live stacked in roughly virtual list, waiting for more than researchers together with coin to exam them.
This way that nosotros must act on to customer reviews to aid us determine if powered anode rods run every bit they claim they do.
Customer Satisfaction
Most people written report that they are happy amongst their powered anode rods, specially inwards the power of the rod to apace eliminate the eggy aroma that tin can prepare inwards water heater tanks. Few come up dorsum after years of purpose to confirm that the H2O heater tank has been adequately protected. However, I would hardly await this.
What I would expect, based on man nature is for soul to come back inwards a few years’ fourth dimension together with edit their review to say that they but had to supplant their water heater because the tank had been eaten away. As I can discover no such reviews, I’one thousand going to get ahead in addition to tell that this has not happened.
There was, nevertheless, a different variety of update or review from a small part of users. A few reviewers report that the powered anode rod failed prematurely.
I wouldn’t tell this is a representation of the engineering’second effectiveness merely rather blueprint standards together with lineament control slips.
However, it is a business concern that manufacturers appear to take remedied inward a satisfactory way. They have attached a long warranty (up to 20 years!) to their devices. Before we get as well philosophical most the integrity of manufacturers, we would need to read the fine impress of the warranty, only to me, they’ve pose (just about) of their coin where their oral cavity is.
How Long Do Powered Anode Rods Last?
Powered anode rods are much more expensive than their depression-tech contemporaries. That’second fine if they terminal every bit long every bit they are supposed to because this toll is often lower than what y'all would pay on replacement sacrificial rods throughout a H2O heater’s life.
The overall consensus is that powered anode rods at least 6 years. At their minimum, they surpass sacrificial anode rods past at to the lowest degree one yr since sacrificial anode rods terminal virtually 3 to v years.
If this was the average lifespan as opposed to the average minimum lifespan, so I would probably tell we should all stick to the inexpensive sacrificial anodes.
Thankfully, it’s not the average lifespan. This is more than about the 10-fifteen twelvemonth mark. Corro-Protec, a Canadian powered anode rod fellowship, is confident that their powered anode rods will last at least xx years too they turn over you lot a xx-year warranty to give acceptance to their claims.
Considering that H2O heaters last nigh viii to xv years, it is likely that your powered anode rod will solely have to be replaced once. It may fifty-fifty outlive your H2O heater, and if it does, in that location is zip stopping you lot from transferring it to your new water heater.
Despite what seems similar a miraculous lifespan for an anode rod, in that location are more or less factors that can bound the lifespan of a powered anode rod.
Powered Anode Rod vs Sacrificial Anode
The manner of corrosion prevention is non the entirely departure between powered anode rods and sacrificial anode rods. There are many more differences betwixt powered in addition to sacrificial anode rods. Below is a summary of these.
| Powered Anode Rod | Sacrificial Anode Rod |
| Uses electrical current to forestall corrosion. | Uses sacrificial corrosion of the rod to preclude corrosion of the H2O heater tank. |
| Replaced when they malfunction. | Replaced when depleted. |
| Average lifespan of x-fifteen years. | Average lifespan of 3-five years. |
| Cost up to $170. | Cost between $15 and $75. |
| Typically made from the same material across brands in addition to models. | iii master materials (magnesium, zinc alloy, together with aluminum). |
| The rod does non corrode. | The rod does corrode. |
| Requires electricity to role. | Functions without a ability furnish |
The 2 almost mutual materials that sacrificial anode rods are made from are aluminum in addition to magnesium. These are used in unlike circumstances because of their differing properties.
In improver to the above general differences, further differences tin be revealed when powered anode rods are compared to aluminum together with magnesium individually.
Aluminum Anode vs Powered Anode
One of the almost noticeable differences betwixt aluminum anode rods in addition to powered anode rods is the large cost departure. Aluminum anodes oft toll entirely $xx to $xl spell powered anode rods tin price more than $150.
Another stark difference between the 2 is how they work in different kinds of H2O. While powered anode rods tin can go good in hard, soft, and softened water weather condition, aluminum anode rods only run well in hard and naturally soft water conditions.
If the H2O has been artificially softened, and so aluminum is not going to live the best protection for your tank.
Magnesium Anode vs Powered Anode
Although less extreme than the price comparing for aluminum rods, a notable divergence betwixt magnesium anode rods together with powered anode rods is the toll. While magnesium anode rods are well-nigh $75 on average, powered anode rods can toll more than than $150.
Magnesium rods are besides more limited than powered anode rods when it comes to the multifariousness of water qualities that they tin can go in. Magnesium rods are best suited to artificially softened H2O. Their extreme reactivity is sufficient to handgrip the excessive quantity of corrosive ions inward this H2O, merely it is a decided drawback inwards naturally soft or difficult water.
Are Powered Anode Rods Worth It?
Powered anode rods are pricey compared to their sacrificial counterparts. You saw this inwards the previous sections. However, a larger outlay tin can oft relieve yous fourth dimension, problem, and even money in the long go. Is this truthful of powered anode rods?
Well, the scientific discipline is audio, client reviews indicate that powered anode rods work good as well as deliver on benefits like removing odors from hot H2O, too many manufacturers reach long warranties to back up their claims.
This means that they will save yous the fourth dimension too hassle of replacing the anode rod every few years. Some may at once view this to be worth the extra outlay of coin for the powered model. Some demand a fleck more convincing—or dollar sign proof.
So, allow’sec look at whether they are more than price-effective than sacrificial anode rods.
- They are probable to final the water heater’s lifespan; permit’second telephone call it an average of 12 years.
- If normal anode rods are used, they accept to live replaced every iii-v years; permit’sec call it four years for the sake of our calculations.
- So, the rod will live replaced 3 times inward the water heater’second life.
- The average toll of a regular anode rod is $45.
- Multiply this past iii too you lot go $135.
- This is however less than the average price of $170 for powered anode rods.
- Moreover, it costs virtually $one.36 to power the powered anode rod each twelvemonth.
- Over the H2O heater’sec 12-yr lifespan, this will add up to $16.32.
- This makes the full deviation $135 compared to $186.32.
Looking at it like this, powered anode rods are non more than cost-effective than regular anode rods.
However, if you lot view the extra $51.32 to live a inexpensive toll to pay for never having to wrestle your erstwhile anode rod out of the tank or even call up to make this, and so get for the powered choice.
Additionally, if yous are not soul who feels capable of changing your anode rod yourself (or doing and then voids the water heater warranty), and then yous add together to each $45 dollar replacement rod price, a $200 plumber installation fee.
Who Makes the Best Powered Anode Rod?
At this signal inward the article, y'all may or may non accept decided whether you lot’d like to invest in a powered anode rod.
If yous take decided to purchase one, so let me to steer you lot inwards the right direction. In club to go the best powered anode rod on the market place, I recommend Corro-Protec.
Their powered anode rods hope to protect your H2O heater tank from corrosion, reduce sediment make-upwards inward the tank, together with eliminate olfactory property from your water.
Along amongst these benefits, the Corro-Protec powered anode rod besides comes alongside a 20-twelvemonth warranty.
Their powered anode rods are as well fairly universal since they work amongst several makes, models, in addition to brands of H2O heaters. They as well come in a variety of unlike sizes.
