Sacrificial anode life

Bobster, that anode looks brand new ! Take a wire brush to clean it a bit and put it back in. 

This is what a worn one looks like. Geyser was installed in Nov 2017. I got a replacement one (HeatTech and Kwikot use exactly the same anode) and installed that. 

I replaced my 3KW element with a 2KW element, as per 87Dream's recommendation. I also replaced the gasket at the same time. 

When the element flange was off I saw how bad the anode was and had to hunt for a replacement. Eventually found one at Leroy Merlin and was pretty cheap @ R133. 00.

I think the anodes wear at different rates depending on the water quality. I did not expect mine to be that bad at just under 4 years.

Thanks @GreenMan. That's more what I had in mind when I think of a sacrificial anode that has truly done some sacrificing.

@hoohloc I was having mine changed every 2 years. The one in the photo is about 2 years old, so I can probably push the intervals out some. You understand the idea? The material on the anode is attacked instead of the geyser itself. So by changing the anodes every couple of years you should prolong the life of the geyser.

This is my kwikot 50l after 1 year with hard water element! I had to replace one geyser and the element on this one during level 5 lockdown at massive expense (plumbers had us by the [email protected]#ss). Our water is from a borehole to estate and treated at source, but even so eats everything. This is also why I have hesitated to install a pump solar geyser as it will stuff up the pump in 6 months. It all depends on your water conditions and location.

ITS solar sells a 4watt electric annode, unbelievably expensive though, might be worth the expense though if it saves you the inconvinience of having to change your annode so often.
