An integral part of comfort in modern life is hot water. In the event of an accident or in the case of a scheduled repair of the hot water supply system, the problem of providing it becomes very relevant.
The centralized hot water supply is carried out either according to an open scheme or closed. The principle of a closed circuit is that in water heaters, cold water is heated by steam or hot water from heating networks. Water heaters are installed directly in buildings or in central heating points. An open circuit suggests that hot water is drawn by the consumer from the heating network, which, in turn, eliminates the need for installation of water heaters, reduces the likelihood of corrosion of pipelines.
All that is required is the addition of large amounts of water to the systems that have previously been treated, which eliminates the corrosion of even the most vulnerable pipelines.
In hot water systems, corrosion of pipelines under the influence of oxygen, which is contained in water, can occur very quickly due to oxidation of steel. For this reason, hot water can only pass through steel pipes with corrosion protection (most often it is a galvanized pipe). To reduce pipe corrosion, special water pretreatment is carried out immediately before it is fed into the system in order to reduce the amount of oxygen in it. Also, an artificial increase in water hardness leads to a decrease in corrosion, because salts deposited from hot water settle on the surface of the pipes in the form of a protective film.
Hot water is purified from impurities using chemical reagents, or purification is carried out without them. For household use, cleaning with reagents is not used. Typically, for such cleaning, a main filter for hot water is used , which is a filter jug based on ion exchange. The power of the filters depends on their size and the diameter of the cell of the filter element. A special thickened plastic layer or stainless steel is the material from which almost all filters for hot water are made. Install filters on the water main of an apartment, cottage or cottage.
In addition to filters for hot water, in order to control the flow rate and save money (when paying for consumed water), cold and hot water meters are installed in the living room.
Currently, there are more than a hundred models and modifications of meters from different manufacturers. There are ultrasonic, mechanical, as well as electromagnetic meters for hot and cold water. Among them, the most common were and remain mechanical products. Mechanical meters differ from the rest in increased reliability, long service life, measurement accuracy and ease of installation. Meters are quickly mounted in the water supply system and take up little space.
As a result of the installation and registration of water meters, you can count on reducing the size of bills for utility bills .
