Hot water is an essential part of comfort in modern life. In the event of an accident or in the event of a scheduled repair of the hot water supply system, the problem of providing it becomes very relevant.
Centralized hot water supply is carried out either according to an open scheme, or according to a closed one. 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. The open scheme assumes that hot water is taken by the consumer from the heating network, which, in turn, eliminates the need to install water heaters, reduces the likelihood of corrosion of pipelines. It is only necessary to add a large amount of pre-treated water to such systems, which eliminates corrosion of even the most vulnerable pipelines.
In hot water systems, corrosion of pipelines underexposure to oxygen, which is contained in water, can proceed very quickly due to the oxidation of steel. For this reason, hot water can only pass through steel pipes with anti-corrosion protection (most often it is a galvanized pipeline). To reduce corrosion of pipes, a special preliminary treatment of water is carried out immediately before it enters 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 the s alts that fall out of hot water are deposited on the surface of the pipes in the form of a protective film.
Hot water is purified from impurities with the help of chemical reagents, or purification is carried out without them. For domestic use, cleaning with reagents is not used. As a rule, for such cleaning, a hot water main filter is used, which is a jug filter operating on the basis of ion exchange. The power of the filters depends on their size and the diameter of the cell of the filter element. A special thickened layer of plastic or stainless steel is the material from which almost all hot water filters are made. Install filters on the water mains of an apartment, cottage or cottage.
In addition to hot water filters, in order to control consumption and save money (when paying for consumed water), cold and hot water meters are installed in the residential premises.
Currently, there are more than a hundred models and modifications of counters from different manufacturers. Existultrasonic, mechanical, and also electromagnetic counters of 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 expect to reduce the amount of bills for utility bills.
