Can Boiling Transform Hard Water

Boiling water can kill or remove several impurities in drinking water. But can boiling hard water make it soft?

Boiling water will remove temporary hardness – that’s hardness caused by magnesium and calcium carbonate.

You might have seen white flakes in your kettle or coffee pot after using it to boil water, leading you to assume that boiling your water can indeed soften it.

To understand more about temporary hardness and how it is removed by bringing water to a boil, let’s look in detail at the difference between temporary and permanent hardness.

Does Boiling Hard Water Cause It To Temporarily Soften?

You should boil water for at least two minutes to remove temporary hardness. The time it takes to boil a kettle is enough to cause magnesium and calcium carbonate to precipitate.

How Long Should You Boil Water To Remove Temporary Hardness?

First, boiling your hard water won’t completely soften it anyway. Even if you manage to remove the temporary hardness, it will still contain dissolved minerals in the form of permanent hardness.
