Hard Water vs. Soft Water – The Facts

Most people already know about water hardness and the damages and negative effects such issue causes, but what are exactly such negative effects?

Here, we will take a look at such effects and analyze the statistics about the overall deleterious effects of hard water in the households that suffer from it. And also the main differences between hard water and soft water.

The first thing that may come to mind for most people when talking about hard water is the scale. It is a well-known fact that the salts dissolved in hard water tend to build up in the form of limescale, the chalky substance that constitutes the water spots left behind when water dries over a window of glass.

Depending on the level of hardness in a household, such buildup of limescale can be quite considerable. A recent study showed that, when used with hard water, a water heater will lose half of its efficiency in 15 years while a water heater used with soft water retains all of its efficiency in those same 15 years. That means that, after 15 years of being used with hard water, a water heater will work at half its capacity and consume the same amount of electricity or fuel to provide just a half of the results it provided when new.An image showing some of the problems caused by hard water

Shower heads are also affected and, when used with hard water, a shower head will lose a 75% (three quarters) of its flow in just one year and a half (18 months). Shower heads used with soft water, on the other hand, retain their full original flow.

All this is translated into a greater use of water, energy and time as all the appliances exposed to hard water start to rapidly losing their efficiency. In fact, it has been estimated that if you have hard water then, by installing a water softener, you can save as much as $100 USD per month.


Additionally, laundering becomes more expensive: when you wash your clothes (with washing machine or manually) you will have to use twice as much detergent than if you do your laundry with soft water; and, in the end, the fabric of the clothes washed with hard water end up looking dingy, scratchy and feeling harsh; and the life of the clothes is shorten almost by a half. This happens because the excess of salts in the water combine with soap and detergent and instead of forming foam they form a sticky scum known as soap curd, which is useless for washing and cleaning and is also hard to wash away as it tends to stick to any surface, forcing you to use twice as much water too.

And of course this will affect you when you take a shower. Soap curd sticks to the skin, hair and nails, requiring much more water to wash it off, and in the end, leaving drying them: your skin, nail and hair are left dry, dull and lifeless; and the hair is also left hard to manage. Besides that, soap curd is also less effective at getting rid of dirt and the salts reduce the overall efficiency of soap and detergents.


Water is indispensable for life and is used each single day of our lives, that is why hard water becomes such a pervasive and difficult issue; it has no benefits and it affects every single thing it has contact with, effectively poisoning your water supply. And this is why is very important for you to check your water supply and test it as soon as you detect one or more of the effects it has, because, remember that the longest you use hard water, the more money and time you and those who live with you lose.
