The system of heating a multi-storey house is of particular interest, it can be considered on the example of a standard five-storey building. It is necessary to find out how in such a house heating and hot water is functioning.
Scheme of heating two-storey house.
In a five-story building, the central heating is meant, there is a heating industry in the house, there are aqueous valves, thermal nodes can be several.
In most houses, the thermal assembly is locked, which is being done to achieve security. Despite the fact that all this may seem very difficult, the system of operation of heating can be described by available words. The easiest way to take a five-storey house for example.
Scheme of heating home is as follows. After aquatic valves are mud (the mud can be one). If the heating system is open, then after muds, through the inserts there are valves, which are standing with processing and feeding. The heating system is made in such a way that water, depending on the circumstances, could not be taken from the reverse side of the house or with filing. The thing is that the central heating system of the apartment building functions on water, which is overheated, water flow is carried out with a boiler room or CHP, its pressure is from 6 to 10 kgf, and the water temperature reaches 1500 ° C. Water is in liquid state even in very cold weather due to increased pressure, so it does not boil in the pipeline with the formation of steam.
When such a high temperature, the DHW turns on on the reverse side of the building, there the water temperature does not exceed 700 ° C. If the temperature of the coolant is low (this is happening in spring and autumn), then for the normal functioning of the DHW, such a temperature cannot be sufficient, then water on the DHW is coming from feeding to the building.
Now you can disassemble the opening system of the heating of such a house (this is called an open water intake), such a scheme is one of the most common.

Principle of operation of the elevator node
Connection diagram of heating boiler.
Water that comes and has high temperatures entering the elevator node. It functions on the principle of the injector, only water is used instead of air. Through the nozzle of the elevator, the coolant with high pressure and temperature passes, then water from the return is recycled in the heating system. Thus, the temperature of the mixed flow of water is obtained as which is in batteries, and as for excess water, which came, but already cooled, they go to the return highway. According to experts, it is such a heating system that is most effective.
In the thermal node there are valves for heating an apartment building (the scheme is different, only an entrance can be involved). This system is possible when the collector is installed, there are several valves on it. And on entering the house, the location of the heat meter is possible, it can be on the house or for a separate entrance.
About the heating system of a multi-storey building
The system of heating at home is usually one-tube; Spill or upper, or bottom. As for the return and feed, they can be placed in the basement, but it is possible that the return is in the basement, and the feed is located in the attic. The movement of water in the risers can be passing and go from top to bottom or counter and go from bottom to top (in this regard, what is the value of the home heating scheme).
Heating system.
There are such risers that are used with the counter coolant may be passing. If the home heating scheme is precisely this, then in any system there is a riser of a heated towel rail (while the system can be both open water intake and closed).
The number of sections and the size of heating radiators is very important. Such parameters must be determined by calculations, as water cools in the coolant. In this regard, there is one good advice: if there is a desire to replace radiators to newer and modern, then you should not use familiar services, as it is necessary to take into account the promotion and cooling of the coolant. In this case, it is recommended to use the services of the company serving the house, and do not throw jumpers, as the company is interested in recovery.

Thus, it becomes clear that the multi-storey house is heated by a fairly simple, but very efficient system. Nevertheless, if some failures occurred, then it is not necessary to repair yourself independently (especially if there is no appropriate training). In any case, you must necessarily call masters from the service company, which, as a rule, eliminate all problems in the shortest possible time. The masters apply the following tools:
- tube (gas) key;
- adjustable key;
- pipe bender;
- Crimp pincers.
With such tools, all problems are quickly eliminated.
