Each of us drinks on average several cups of coffee or tea a day. Sometimes the kettle heats up for so long that there is simply no strength to wait. Maybe it's better to pour hot water into it right away, it will boil faster? There is a certain logic in this, but everything is not as simple as it seems. Sit back and remember why you shouldn't pour hot water into the kettle.
1. Main reasons
In this case, we mean centrally heated water. Before getting into our taps, the cold liquid goes through a series of purifications. It is suitable for both coffee / tea and cooking.
At first glance, there are no obvious differences between cold and hot tap water, other than temperature. It is also cleaned and stored in special tanks. However, the main difference between liquids is their chemical composition.
2. Composition of hot water
In order for the hot water pipes to function properly, certain substances are used. Chemical reagents prevent rust and disinfect pipes.
A small proportion of chemicals that do not exceed sanitary standards can remain in the water. However, when consumed regularly, impurities can negatively affect health. The most dangerous are lead ions and polyacrylamide.
Why pour liquid with additional impurities into the kettle if you can use purified cold water? So you get high-quality boiling water without harmful additives.
3. Requirements for the quality of hot water
The tap liquid heated in the boiler room is considered technical. According to sanitary standards, it refers to water that should be used only for domestic and household needs.
Important! Cold water is considered to be potable and suitable for cooking. Higher requirements are put forward for its quality, and lower requirements for technical ones.
During the heating process, water passes first through the boiler pipes, and then through the water pipes. The high temperature helps to dissolve deposits that form on the walls of the pipeline. That is why there will be much more impurities in water heated to 60-70 degrees than in cold water.
In addition, special softening agents are added to the liquid circulating through the heating elements. They prevent the formation of limescale, which can clog the pipe openings and damage the boiler. You may not even notice additional impurities in the water, but they will gradually accumulate in the body. Without an urgent need to drink such water is not recommended.
4. Is the water heated in the column suitable?
We figured out the hot water supply, but another question arises: what about the gas water heater or self-heating of water? The situation here is more complicated.
Neither the gas equipment manufacturer nor the sanitary authorities guarantee that the liquid will retain its original composition after heating. However, there is no ban on the use of such water either.
It is impossible to give a clear answer, since the hosts' speakers are in different states. It is possible to establish the suitability of water for drinking only with the help of a separate examination for each source.
On the other hand, the liquid heated by the column raises concerns. The process uses copper pipes that release copper ions into the water. There is no official ban on the use of such liquid, so whether to pour it into the kettle or not is up to you.
5. How does hot water affect the kettle?
Cold water is the most useful liquid for both a person and a kettle. It is cleaner in composition, contains a minimum amount of lead and other chemical impurities.
The quality of water affects not only human health, but also the duration of the kettle. The hot liquid flows through numerous pipelines and collects salt deposits from the metal elements. That is why, when heated, it forms a large amount of scale.
Deposits build up on the inner walls and the heating element rather quickly. Scale can get into our body through drinks. Due to lime deposits, heating elements (heating elements) break down and are not always subject to repair. Scale is difficult to remove and you have to use aggressive substances that adversely affect the condition of teapots.
In addition, the more plaque inside the product, the longer the liquid heats up. Thus, wanting to reduce the time for boiling with hot water, we run the risk of achieving the opposite effect. Moreover, boiling water will turn out with impurities.
Discerning connoisseurs of tea and coffee also note that low-quality water affects the taste of drinks. Therefore, it is best to use cold water for cooking and drinking. Additionally, it is recommended to pass it through a filter in order to be sure of the quality of the liquid. Leave the hot water for household and household needs.
