What is a heating system?

Heating the home in the cold season - longthe established tradition of modernity. And if the residents of hot countries do not need to know what the heating system is, this can not be said about us, not firsthand who know about the harsh Russian winters. A heating system is a set of devices whose task is to heat the premises in the cold season by compensating for heat losses.

The most common and familiar to us systemheating consists of a boiler, piping and radiators. Water is used as a coolant. Since water has the property of expanding when heated, such systems are equipped with an expansion tank.

Types of heating systems

Many have heard, but not everyone knows what isopen heating system. In such a system, the volume of the expansion tank communicates with the atmosphere, which leads to accelerated corrosion of the metallic elements of the system due to the dissolved air in the water, and also to the formation of air plugs. A vivid example of such a heating system is the communal central heat supply of houses.

Similarly, it is explained that such a closed heating system, in which a membrane expansion tank is used, and air intake by a coolant is excluded.

How do the systems

In addition to water as a coolant,used steam. Steam heating is efficient, but as steam is a fairly aggressive environment, such systems are less durable. Air heating does not require the installation of pipelines and radiators and can be combined with ventilation systems. It is most often used in public and industrial buildings. There are various types of heating systems that convert electrical energy into heat.

The choice of any of the above heating systems is based on a preliminary calculation of the cost of equipment, taking into account the cost of its installation, as well as the cost of maintenance during subsequent operation.
