Hot Water Sacrificial Anodes

Ask the expert – Hot Water Sacrificial Anodes

Q1: My neighbours have had to buy a new storage hot water tank because its sacrificial anode failed. What happened?

A: They didn’t replace the anode according to the manufacturer’s instructions and it stopped protecting the system.

Q2: How often should the anode be replaced?

A: In all Hot Water storage tanks – Electric, Gas, Solar and Heat Pump, anode should be replaced every five-seven years.

Q3: Do many people do this?

A: No. If they did they would almost double the life of their system and manufacturers would be more willing to give a warranty longer than 10 years.

Q4: Please explain more.

A: The anode is supposed to slowly degrade and then be replaced towards the end of its life. The degrading process actually protects the tank and its associated components.

Q5: Is it expensive to inspect and replace it?

A: No. It is a fraction of the cost of replacing the tank. The anode protects against corrosion, stops the heating element decaying and the thermostat giving a false sensing that will really hurt your power bill. Check your tanks identification label for its age and if due, (5 years+ old) we will replace if needed and make sure it is regularly inspected
in future.
