The simple thing you can do to extend the life of your hot water heater

The importance of having a hot water service every 5 years.

We’d like to let you know a little secret… A secret that could save you a lot of money OR cost you a lot!

Inside most electric, gas and  solar hot water heaters, there is a special magnesium rod called an anode. All vitreous enamel steel heaters have these anodes installed by the manufacture to protect the tank from corrosion and its replacement can prolong the life of your heater substantially.

How hot water heater anodes work

Also known as ‘sacrificial anodes’, through electrolysis, the anode rod will corrode/dissolve instead of the water heater’s exposed steel through a process called electrolysis.  It protects the metal from inside the hot water heater from rusting. Electrolysis occurs when the two dissimilar pieces of submerged metal react with one another to create a voltage.

Why a correctly functioning anode is so important

The anode’s lifespan is limited to around 3 – 7 yrs depending on the water quality and usage. Once the anode is spent your hot water heater rapidly starts to corrode from the inside. The anode can be replaced quickly at a reasonable cost – but not too many people know this. But they do know that a rusted hot water heater on average will cost between $1200 – $2200 to have replaced.

Hot water cylinders don’t just die of old age! They simply corrode away because the anode inside no longer gives the heater any necessary protection. Most people underestimate the age of their heaters and this can prove very costly!

The alternative is just a simple inspection and anode replacement. It could literally save you thousands!
