Anyone who has a dishwasher will know the effect. A small amount of damage to the cutlery basket will reveal or cause tiny rust enameled pot has a damaged area. During the rinsing process, rust particles can come off, which then settle mainly on cutlery. Not only does it look unsightly, it can also only be removed mechanically. A balled up piece aluminum foil in the cutlery basket can prevent this. The aluminum foil acts as a sacrificial anode, so to speak. Do you remove that? Piece of aluminum foil you can see that there has been a surface change here. This sacrificial anode comparison would like to tell you a lot more about sacrificial anodes.
What does a sacrificial anode do?
Anyone who might still remember the chemistry lessons in the... Schooling If you remember, you might remember the electrochemical voltage series. She assigns each of the metals a place in the row. The metals in the lower row are less noble than those in the upper row, which means that the exchange of electrons always takes place from the less noble to the more noble metal. Ale Example: Zinc is less noble than iron. This means that the zinc electrodes will always jump to the iron and not the other way around. Zinc rusts - iron does not. Water acts as an electrolyte.
- Areas of application
Sacrificial anodes are not only used in boilers or storage tanks as well as in heating technology. Our sacrificial anode recommendation also applies to the pump in the pond or a galvanized roof. Sacrificial anodes are even essential in shipping, and suitable sacrificial anodes are required for underground pipelines or drilling rigs.
Use in different types of water
Different sacrificial anodes are required for different types of water.

| salt water | Very high salt content with best electrical conductivity | Zinc sacrificial anode |
Our sacrificial anode rating
As we mentioned, sacrificial anodes are essential for many applications. In the Budget They are usually needed as sacrificial anodes for dishwashers or hot water boilers. Basically, wherever metal meets water, something will rust!
Sacrificial anode for hot water tanks
A galvanic cell is created in it by combining two different metals meet in an electrolyte (water). The sacrificial anode corrodes while the sheet steel casing of the hot water tank remains intact. Even if this cover is galvanized or enamelled, there may be tiny defects. Over time, rust will form and the device will leak. A rod or chain-shaped sacrificial anode made of magnesium prevents this. See also our sacrificial anode comparison winner from the table. If the sacrificial rod anode is worn out, it must be replaced, which is usually necessary at intervals of around 2 years. The hot water tank should also be flushed as the magnesium accumulates as sludge ground drops off.
Sacrificial anode for pool
Especially with salt water pools, which are becoming increasingly popular, they are very pleasant for people, but not for the material. The metal ladder is often the weak point here. If it is made of stainless steel, the oxygen dissolved in the water attacks the metal and it oxidizes. The cause is the galvanic cell, where electrodes are removed from the metal. The base metal here is the pool ladder. A Piece of base metal, the sacrificial anode, can stop this process.
This is how you test a sacrificial anode
There are three different measuring methods: visual inspection, the use of a signal anode and current measurement. The manufacturer's operating instructions must always be followed.
- During the visual inspection, the sacrificial anode is removed. If the diameter of the sacrificial anode is quite small or there are a lot of deposits on it, it needs to be replaced.
- When measuring current, the sacrificial anode, which is installed in isolation, does not have to be removed. The test is carried out using an anode tester or resistance measuring device. If the measurement is > 0,3 mA, the sacrificial anode is OK; if it is < 0,3 mA, a visual inspection must be carried out to judge the condition.
- Using a signal anode is the easiest way to determine the consumption of a sacrificial anode. If the signal generator shows a red color, the sacrificial anode is used up.
