Why is it forbidden to pour distilled water into an iron with a steamer?

Most companies manufacturing household appliances indicate in the instructions that distilled water should not be poured into an iron. In this case, the use of tap water causes the appearance of scale on the heating element due to the salts contained in it. We will understand why such a ban was introduced, whether there are reasons for it and how to fill the tank so that the home steamer lasts as long as possible.

Steam iron

How does a steam iron work?

From ancient times it is known that if you iron moistened things, the result will be better. Liquid-impregnated fabric fibers become softer. Evaporating, moisture reduces friction between individual fibers. When ironing was used, wet gauze or a spray gun was used to spray the garment before ironing.

Today, a special unit, a steamer, has been introduced into the design of the iron. It includes a reservoir in which water is contained, and a device for regulating its supply to the heating element. Upon contact with a hot heater (its temperature is about 150 ° C), water instantly turns into steam. But the salts contained in water cannot turn into steam - they settle in the form of crusts on the surface of the iron. Thus, scale is formed.

In the instructions, manufacturers recommend using tap water to refuel steamer tanks. But these are general recommendations, they are written without taking into account the peculiarities of water supply in different countries and regions. Far from all areas, the quality of tap water avoids the formation of scale.

Scale in the iron

What is harmful scale?

The crust of salts formed on the heating element adversely affects the performance of the iron. This effect has several manifestations:

  • Salt deposits do not conduct heat well. So, the soleplate heats up more slowly. In this case, the heating element remains in the heated state longer - the risk that it will burn out increases.
  • In case of steam blow, the pieces of scale can fall off from the heater and fall into the tubes through which the steam comes out, clogging them. This reduces the quality of steaming linen, negatively affects the result.
  • Getting on the sole, the scum is “smeared” over the clothes, leaving white traces and stains. It is very difficult to remove these stains from the fabric.

If the iron fails due to scale deposits, most companies will refuse to repair or replace equipment under warranty. The responsibility to monitor the condition of the iron and to clean it from scale in a timely manner rests with the user. Violation of the cleaning regime and the use of unsuitable water is equivalent to intentional damage to equipment and does not fall under warranty.

To reduce the risk of scale formation, some cartridges incorporate special cartridges that reduce water hardness. However, the cost of such models is significantly higher than that of conventional irons. Therefore, most users should understand how to refill the iron is possible, and what is not.

Ironing with distilled water

Why can not distilled water be used?

The distillation process removes from water 99.9% of the salts contained in it initially. The liquid obtained after such cleaning, at first glance, should ideally be suitable for the operation of a steam generator or a steamer in an iron. However, manufacturers say that distillate has two significant drawbacks:

  • The boiling point of water, completely devoid of salts, becomes higher. So the distillate evaporates more slowly. This increases the load on the coating of the evaporation chamber.
  • Some salts (such as hydrocarbons) increase the pH of water. If removed, the liquid will become more acidic.This means that its destructive effect on metal will intensify, corrosion processes will go faster.

Some experts believe that the ban on the use of distilled water is a ploy of manufacturers. The purpose of the trick is to accelerate the failure of the iron, and hence the purchase of a new one. However, supporters of this point of view are in the minority.

The use of distilled water can extend the life of the iron. But for this you need to mix the distillate with tap water. The proportions depend on the water hardness in the region. The most commonly used ratios are 1: 1 and 1: 2.

Ironing with filtered water

What kind of water to pour in the iron?

Today, there are several options for refilling liquids for irons:

  • Special solutions with optimal pH and boiling point. They have a minimum content of salts forming insoluble crusts. Perfume components are added to most solutions. The main disadvantage of such liquids is the high price.
  • Tap water. This option is suitable only for areas with soft water. But in most areas of our country, the water is too hard.

For most users, it will be optimal to use either a mixture of tap water with distilled water, or water passed through a household filter with a softening cartridge.

    I have been using distilled water for more than 5 years. Purely. No scale. I have such a job, every day I iron for 2-3 hours.
    Before that I used plain water. The iron then failed a year later. So much scum was accumulated in a week. Picked out and re-picked. Something hurt.

      Of course, the call to use distilled water is pure deception! pH dist. water is equal to 7, i.e. it is neutral. Alkali actively corrodes, for example, aluminum. Try holding the aluminum plate at the end. caustic solution (NaOH) - and you will see how the surface acquires a very noble matte texture. About raising the boiling point, this is just a "clinic"! It is in distilled water that it is equal to 100 degrees, and with an increase in the number of salts it does not increase, because the water evaporates as usual, at the same temperature of 100 degrees, and the salts do not evaporate, but settle in the iron, incapacitating it, closing TEN! It’s just beneficial for the company that you are buying a new iron! The sooner the better!

    RAVE! The boiling point of distilled water is EXACTLY 100 degrees Celsius (salt-MORE). Cold distilled water can absorb carbon dioxide and becomes slightly acidic (pH 5.4-6.6). But it is very small, for any harm. Soft water also contains salts, which, when evaporated, remain in the iron and spoil it. (The misconception that soft water does not leave scale is based on the observation of scale precipitation in a kettle, BUT there the water almost does not evaporate, and in the iron it evaporates completely). Therefore, for irons only distilled water is applicable.

    In professional steam generators (in other words, steam irons in the sewing industry), ONLY distilled water is poured. Any other liquid is strictly prohibited by the instructions of the device manufacturer. As a production mechanic, once a year, before vacation, I disassemble the distiller, clean and rinse the tank and the heating elements. A lot of scale and some clay small mucus, river water from the city network after cleaning. I pour only distillate into the iron home. The article is either custom-made, or someone decided to troll readers and spark controversy.

      Namely, that "professional steam generators", and the speech in the article seems about mass irons.

      They wrote about: “98 gasoline is being poured into the Bugatti Veyron. Any other is strictly prohibited. As a minder, I serve Veyron. And in my UAZ, instead of 76 pour 98, there was almost no detonation and almost nothing burned out. ”

      Household irons are designed for ease of maintenance (i.e. tap water) and for a short service life. Therefore, do not be so categorical. Although the article does not reveal the answer to the question posed in the title, I did not see outright stupidity there.

    We use filtered water by the reverse osmosis method (this is almost distillate) and there are no problems with the iron, nor with the steam cleaner, nor with the steam generator. Distilled water is NEUTRAL. The boiling point is more dependent on atmospheric pressure than on salts. For example, on the 25th floor it can be 3-5 degrees lower than on the 1st.

    The author heard a ringing, but does not know where he is. Indeed, if you take distilled water, pour it into a vessel perfectly polished from the inside and, protecting it from shocks and vibration, heat it, you can reach temperatures of more than 100 degrees Celsius without boiling. But all this is absolutely impossible for the iron.

    you don’t need to be an expert to understand why manufacturers prohibit the use of distilled water: in this case, the equipment failure is sharply reduced))
    I went over and repaired more than a dozen irons, and the reason is the salts that clog the jets and disrupt the sealing of silicone cuffs. for the same reason, the iron leaks immediately after filling it with water. And yet, I often observed the following picture: the silicone sealant adapter is breaking the scale. therefore, even a newly purchased branded iron “drunk” with tap water is carried into service ..

    I read the comments. So everyone seems to be right, but not quite.
    1. Manufacturers usually write “the iron is designed for use with tap water” - everything is correct here. When developing mass technology, it is natural to focus on the masses. It would be foolish to narrow the audience by tying the equipment to distilled water.
    2. The boiling point of distilled water (ceteris paribus and natural conditions) is really lower than that of tap water. But! Vaporization depends not only on the boiling point. Microscopic particles of salts stimulate the formation of steam (something like this can be observed when adding salt to boiling or even boiling water). Accordingly, all temperature conditions, evaporator chambers are designed specifically for tap water.
    3. Some irons use integrated water softening cartridges. According to distilled water, the contents of the cartridges will be washed out faster.
    4. Well, of course, all the instructions are written not only for users, but also for passing many certifications (and in a bunch of countries at the same time). Those. if manufacturers wrote that the service life is 3 years, then for certification, please describe all measures so that the iron retains its properties for all three years, and then let it burn with fire.

    Summarizing. The technique is made specifically for the use of tap water. This is statistically beneficial to the average user, and to the manufacturer.
    A manufacturer gets more sales and a natural failure through time.

    Actually, I described why the manufacturer does not recommend distilled water. But what water to use is up to you. Choose. Either the ideal operation of the device within the operating life, or the eternal, but mediocre iron.

    I pour only distilled. Although the equipment is not designed for it, I’m used to respecting things even to the detriment of comfort.
