Hotwater Service Anodes

Depending on the make and type they can have oneMine has and I check it annually.

Look on the top of the cistern and see if there is a plug in the centre If so the anode is under that. Its about a metre long in mine

It is an Aquamax enamel coated steel cylinder

My gas hot water system at home is nearly 20yrs old and I have never thought about an anode, but either way, I won't go looking now.

If you have an instruction manual it should tell you........I've never looked at mine ??

Our Solarhart HWS has an anode, Rodney, and I got the local plumber to change it after 5 years of being on this Winton bore water. Not sure there was too much left, he said.

Depending on the water you're on, every 12 months might be overkill. But then they are cheaper than a new system. Yes, I'd say your home one would have one too.

We live in Perth and use a Solar Hart solar water heater.
Solar Hart service it every 5 years and at the same time replace the sacrificial anode.
It lasted 25 years and died – we replaced it with another Solar Hart.

People consistently fail to change the anode in their hot water systems ..... as a result they usually fail from corrosion after about 10 ish years.

I doubt that you need to change them evey 12 months ..... but every 2 or 3 or 5 years would not be a bad idea. ..... but it is very rarely done.

Don't be surprised if you have difficulty getting one or people don't know what you are talking about.

I spoke to the ref from Saxon one time ...... told me they have an anode available as a spare part but have never sold one.

In a lot of HWS it may be impossible to replace the anode because of where the unit is installed ..... and you will need a pretty large socket and a breaker bar ... they generally come out the top and are full length.
