What kind of water to pour on the stones in the bath: cold or boiling water? Understanding the issue

Newbies in the bathing business often ask themselves the question: what kind of water to pour on the stove - cold, hot or any? Experienced people are not puzzled by this problem and pour what is at hand. This is, of course, a joke. But what really should be the optimal temperature of the water with which the stones are poured? And in general, is there a difference in this? Let's try to figure it out.

What is the Evaporation Process? Let's get a little clever ...

Evaporation is the transition of water from a liquid to a gaseous state. The reverse process, when steam turns into water, is called condensation. Steam is water molecules that are detached from the structure of the liquid under the influence of kinetic energy, which turned out to be stronger than the intermolecular bonds of water and was able to break them.

Kinetic energy is converted heat energy. When water is heated, the speed of movement of molecules increases - this is how kinetic energy (movement) appears. And at a water temperature of 100 degrees Celsius, water molecules receive enough kinetic energy to break away from the liquid and turn into steam.

Consequently, the higher the surface temperature of the evaporator, the role of which is played by the heater, the faster and more intensively the water turns into steam. And one more thing: the vaporization process depends on the area of ​​the heated surface and the amount of liquid supplied to it. That is, the larger the heated element and the less liquid, the faster it will turn into steam. Boring? But this is important further!

So what kind of water to pour on the stones?

Let's consider the options. There are only three of them.

Cold water sharply cools the stones, as a result of which it does not evaporate immediately. A cooled surface cannot transfer enough kinetic energy to water molecules so that they instantly turn into a gas (vapor). There is a danger in this, since water can flood the firebox or get on the heating elements.

Steam from cold water is less hot and therefore condenses intensively when it comes into contact with cold surfaces. It looks like a cloud and is called heavy or damp because it warms little, humidifies the air and makes breathing difficult. And all this is not very good for health. In addition, such steam can have a "swamp" smell.

In order to pour cold water, the heater, roughly speaking, must be red-hot and have a sufficiently large area. But why this is done is not clear, since there should be no problems with hot water in the bath.

Conclusion: it is not worth pouring cold water onto the stove. Especially if several visits are planned to the bath: cold water will cool the stones, and heating them again will take time and increase the consumption of firewood / gas / electricity. In addition, stones with such a temperature difference can crack.

Boiling water, unlike cold water, already has high kinetic energy and not much heat is needed to convert it into steam. Here, the phase of transition from liquid to gas requires less time and energy. And also the water heated to high temperatures practically does not cool the stones.

The steam from boiling water is light, dry and hot. It quickly heats up the room, destroys everything harmful in the air and, in general, is good for health. But strong steam for an amateur - not everyone can withstand it. You need to get used to it.

Conclusion: hot water can and should be poured onto stones; this is especially true for saunas with small heaters. But only this must be done carefully so as not to harm.

Another option is warm water. There is nothing special to say about him - he is neither there nor here! But of course, it is better to pour warm water than cold water. In general, pour either boiling water or hot water over the stones. And do it in small portions - 200-300 ml. All with light steam!
