Magnesium Vs. Aluminum Anode Rod: What’Second The Departure?

Anode rods are installed inwards H2O heater tanks to prevent them from rusting or malfunctioning. While magnesium in addition to aluminum are ii of the nearly widely used metals used to manufacture anode rods, many homeowners are unsure of the differences betwixt these anode rods. 

Magnesium anode rods are normally used inwards hard water as well as render homeowners amongst many wellness benefits. However, magnesium rods corrode faster as well as won’t final equally long equally aluminum rods. While aluminum rods have no wellness benefits, they’re ideal for hard water together with more than affordable than magnesium rods.

If it’second last fourth dimension to supervene upon your water heater tank’s anode rod, nosotros’ll explain everything yous should know well-nigh how magnesium as well as aluminum anode rods differ! By comparing these anode rods, yous tin can ensure you lot purchase the correct replacement for your H2O heater tank.  

Magnesium Vs. Aluminum Anode Rod: How Do They Differ?

While magnesium too aluminum anode rods keep your H2O heater working properly, they are non the same. To assistance you lot empathise how these anode rods differ, we volition compare them in terms of blueprint, installation, water pH, water odour, sediment buildup, wellness effects, lifespan, as well as cost. 

Magnesium Vs. Aluminum Anode Rod: Design 

Magnesium anode rods are lightweight, which makes them slow to transport and install. While magnesium is the master metallic used, there are many describe metals used inwards the structure. This pattern way magnesium is more reactive to corrosive elements than magnesium rods, which allows it to operate rattling effectively. 

Aluminum anode rods, still, are ordinarily used for their blueprint. These lightweight rods are flexible, making them easier to create anode rods for water heater tanks of unlike shapes together with sizes. These rods are as well slowly to install. The design of aluminum rods also way they perform more than efficiently inward hot H2O. 

Magnesium Vs. Aluminum Anode Rod: Installation

Magnesium anode rods are slow to take away too supersede. However, equally aluminum anode rods erode, they get-go to slap-up. Due to this, it tin be hard to take aluminum anode rods when it’second fourth dimension to supplant them. In damage of how slowly these rods are to install too supervene upon, magnesium anode rods come up out on meridian!

Magnesium Vs. Aluminum Anode Rod: Water pH

One of the main differences betwixt these anode rods is how they handle different water pH levels. Alkaline H2O amongst a high pH is referred to equally hard water, spell amongst lower pH levels is described every bit soft H2O.  

Magnesium anode rods are better suited to soft water. Since these rods are non able to withstand the number of minerals inwards hard H2O, the corrosion of the rod is exasperated, which reduces the lifespan of the magnesium rod. 

Aluminum anode rods are well-suited for function alongside hard water that has high pH levels. Since aluminum rods are less reactive than the magnesium variants, they tin withstand hard water improve, allowing them to last longer before needing to supercede the anode rod. 

Magnesium Vs. Aluminum Anode Rod: Water Smell

When magnesium anode rods erode over fourth dimension, it tin make an unpleasant hydrogen sulfide odour akin to that of rotten eggs. Unfortunately, this can eventually bear on the smell of yous H2O that’s headed inward your water tank. 

However, aluminum anode rods are normally manufactured alongside zinc. Due to this design, aluminum rods can neutralize unpleasant odors that ofttimes effect from the interaction between metallic and water. In price of how these anode rods touch H2O scent, aluminum rods are meliorate!

Magnesium Vs. Aluminum Anode Rod: Sediment Buildup

Due to the design of magnesium anode rods, they do non make harmful sediments, which agency at that place is no sediment buildup to worry near. However, aluminum anode rods ofttimes loose sediments every bit they corrode, which can issue in a noisy water heater tank. These sediment byproducts tin as well become into your plumbing systems as well as are a potential wellness adventure. In price of sediment buildup, magnesium rods are the better option! 

Magnesium Vs. Aluminum Anode Rod: Health Effects

Many homeowners take magnesium anode rods due to the added health benefits. Magnesium has been proven to pass on people energy, lower blood force per unit area, too assistance inwards musculus movements by helping create poly peptide in your body. By adding magnesium to your H2O through an anode rod, y'all’ll go sufficient amounts of this important food. 

However, aluminum anode rods make not take whatever wellness benefits. However, the aluminum sulfates released into your water will assist the process of purifying water! Overall, inward price of wellness effects, magnesium rods are the improve pick for your water heater tank!

Magnesium Vs. Aluminum Anode Rod: Lifespan

When comparison these anode rods, those made from magnesium volition accept a shorter lifespan. While magnesium rods tin can concluding as long equally 5 years, it depends on your H2O render’second pH degree (hardness) and lineament. Magnesium anode rods may final less than a twelvemonth when used alongside hard H2O.

Since aluminum anode rods are less reactive than magnesium variants, they corrode at a slower rate. Ultimately, this way aluminum rods will last longer. However, equally nosotros mentioned before, these rods peachy over fourth dimension, which tin can make aluminum anode rods harder to supercede eventually. 

Magnesium Vs. Aluminum Anode Rod: Cost

Magnesium anode rods are more than expensive than aluminum rods. While aluminum as well as magnesium are readily available metals, magnesium is harder to extract as well as refine, which leads to higher costs. 

Typically, y'all tin can look to pay upward of $thirty for a replacement magnesium anode rod. Many people prefer purchasing aluminum anode rods because of their affordability. While aluminum rods are cheaper, neither rod volition intermission your depository financial institution! 

Conclusion

Magnesium too aluminum anode rods are not the same! While magnesium anode rods are ideal for hard water, aluminum variants are improve for soft water. While magnesium rods accept many wellness benefits, they corrode faster than aluminum rods, which reduces their lifespan. Aluminum anode rods, on the other paw, have longer lifespans in addition to are more than affordable than magnesium rods. However, aluminum rods take no wellness benefits.
