OK all you plumbers out there, this is probably a dumb question from an electrician. When you run almost exclusively on gas will the anode have less wear? Looked at mine this morning and there is not a lot of material eaten away, it's an aluminium anode in a suburban HWS.
Mind you, when I took it out whole pile of junk looked like rocks and there was a bit of white calcium came out with the water.
HWS I not leaking so I can assume the anode is doing its job. BTW the unit has been operating for 2 years, this would have been its 3rd anode change.

PhilC, I asked a similar question a while back. If the HSW is not in use does the anode wear? The answer was yes. As long as it is submerged, it will wear. Maybe not at the same rate.
Good example yet again to have topics consolidated.

Cheers Larry, my bad, didn't use the search engine.
Thank again mate.

Hi Phil
It makes absolutely no difference what the heating source is
Live of the anode depends on:
The anode material
Magnesium is the usually used, giving BEST protection ,but may have a short life with highly mineralised water
Aluminium, less protection & should realy only be used if the water is highly minerlised & that is just for longer life ,NOT better protection!!
Exposed metal IN the tank, And there will always be a small area of exposed metal, the Anode itself will have some exposed as well as the socket !
Water quality, with demined water only they would almost last for ever
Highly minerarised, perhaps a few months
It is called a sacrifical anode for good reasons & the action is totally electrtic
In electrical terms it is a simple basic single cell.
Anode. cathode,& electroltye,with a closed circuit, resistance dependent on the mineral content of the water & exposed metal area.

Cheers PeterQ, I had a suspicion that was the case, good old galvanic action. We have only rain water here so I recon that may be why the anode looks so good. It gets a look every 3 months so it's a sure bet I will replace it if it looks a bit beaten up.
Hope you are as well as we are mate.
Cheers

No Phil, when in Rome do as the Romans do. Until there is an absolute directive to tidy up this forum and consolidate topics this is the way it will be.

I just replaced the anoid in my daughter,s hot water service in her van witch she has just bought, the anoid was eaten away down to the wire in the centre, the repair centre where I bought the anoid said he has seen them with just the plug, he said don't panic it takes months to effect the heater tank,I have had mine van for 2.5 years and always checking the anoid it is as good as new.

The damage[ corrosion] starts as soon as there is no active material left on the anode support rod,If there are any coating faults in the tank [even pinholes in the lining]
How do you know if there are pinholes in the lining ??
You do not know, unlessyou can closely inspectALL of the inside of the tank
How long it will take for the tank to have a hole eaten through it [leak]will depend on water quality

Yes, that MAY take months or even years
Anodes are much cheaper than a new system
