The heating system of an apartment building with upper wiring

In order to keep our homes cozy and warm, especially during the winter, we need heating. The heating system in apartment buildings is essential to making sure all occupants are comfortable all year round. Upper wiring is a common type of heating system found in apartment buildings. With this system, heat is circulated downward to each apartment from a central source, usually found on the top floor of the building. Let’s examine the advantages of this system and how it operates.

The heating system in an apartment building with upper wiring is typically centralized, meaning that the building’s whole interior is heated by a single source. Because it is frequently found on the roof or top floor, the central heating unit effectively distributes heat throughout the structure of the building. This system usually uses a boiler or furnace to produce heat, which is then distributed to every apartment through pipes or ducts.

The upper wiring heating system’s effectiveness in uniformly dispersing heat throughout the building is one of its main benefits. Since heat rises, placing the central heating unit on the top floor promotes natural convection, which helps warm air circulate throughout the structure. As a result, everyone can live in a comfortable environment with consistent temperatures across floors and apartments.

The upper wiring system’s space-saving layout is another advantage. The requirement for separate heating systems in each apartment, which can take up valuable space and require extra maintenance, is eliminated by centralizing the heating unit on the top floor. Because there are fewer moving parts, this centralized method not only conserves space but also makes maintenance and repairs easier.

Additionally, both building owners and tenants may be able to save money with the upper wiring heating system. Because centralized heating systems allow for better control and optimization of heat distribution, they are frequently more energy-efficient than standalone units. This is a win-win situation for all parties since it can lead to lower utility bills for occupants and lower operating costs for building owners.

Component	Description
Boiler	A heating device that heats water to distribute heat throughout the building.
Pipes	Network of pipes that carry hot water from the boiler to radiators in each apartment.
Radiators	Devices in each apartment that release heat from hot water circulated through them.
Thermostat	A control device that regulates the temperature of the heating system.

In apartment buildings with upper wiring, the heating system plays a crucial role in ensuring comfort and efficiency for residents. Unlike systems with lower wiring, where the heating pipes run beneath the floor, upper wiring setups have pipes running through the ceilings or upper parts of the walls. This arrangement poses unique challenges and advantages. One key advantage is that it allows for easier maintenance and repairs since the pipes are more accessible. However, it also means that heat distribution may be less even throughout the building, requiring careful design and balancing to ensure all units receive adequate warmth. Additionally, proper insulation becomes even more important to prevent heat loss through the upper parts of the building. By understanding the intricacies of the heating system in apartment buildings with upper wiring, residents and building managers can make informed decisions to optimize comfort and energy efficiency.

Features of the upper wiring

When it is not possible to lay the supply and reverse highways with the coolant in the screed, at floor level, or in the basement, water heating with upper wiring is utilized. When installing the heating system with natural circulation, this option of providing the workspace is in demand.

The following are some benefits of the heating scheme with the upper wiring:

• Simplicity of installation. The pipeline can be hidden in ceiling structures or in the attic, which improves the aesthetic perception of communications. When installing highways with a coolant under the ceiling, the placement of furniture should be taken into account, avoiding closing the pipes;
• Low heat loss. Heated air in the room rises up and compensates for the heat transfer of the pipes, so a significant part of the thermal energy enters heating devices;
• Good hydrodynamic indicators. Using the axonometry and methodology of hydraulic calculation, you can design a heating system with a minimum number of angular turns and branches.

The primary drawbacks of the network with the higher wiring are increased material acquisition costs. Additionally, because of the rise in coolant volume, a more potent heating apparatus must be installed.

The network with the upper supply of the working environment may be one pipe or two pipes, depending on the structural characteristics.

One -pipe system

Coolant is delivered to the highest point in single-pipe systems with upper wiring, where it is subsequently dispersed among the radiators. They are distinguished by a sequential battery connection, which results in the heating intensity being dependent on the communication duration and the incapacity to modify the temperature of every heating element. When setting up single-pipe networks, one must take note of the supply pipeline’s inclination, which is 5-7 mm per 1 m.P. in the direction of shifting the workspace. It produces more even heating and enhances coolant circulation.

Single-pipe systems are classified as horizontal or vertical based on where the pipes that connect the heating components are located.

When multi-story residential buildings were being constructed in the early 1950s of the previous century, the vertical scheme with the upper wiring was frequently used. These days, one-story cottages up to 100 m2 in size and houses with four to nine stories are among the places where it is in demand. The following pipeline reinforcement is installed in the radiators of the single-pipe system in order to eliminate system flaws and guarantee efficient heat energy consumption:

• air ducts. Their functions are performed by Maevsky cranes with a cap or under the screwdriver, which serve to remove air accumulation;
• thermostatic and thermostatic elements. They allow you to control the heating temperature of each radiator;
• Scattering valves. Installation of locking valves makes it possible to carry out preventive and repair work without draining the coolant in the system.

Considering the operating conditions and pipeline pressure, the batteries for a single-pipe network with upper wiring are chosen. Models that are cast iron and bimetallic and can tolerate large hydraulic strokes are appropriate for apartment buildings that have central heating. One-story buildings are equipped with cast iron batteries. When the coolant’s composition and acidity are controlled, aluminum heating devices can be employed.

Two -pipe heating network

The two-pipe heating system with the upper wiring is distinguished by the radiators being connected in parallel and by the availability of two coolant highways for the supply and reverse. The first one moves heated air around the workspace, while the second one drains cooled water.

More supplies and parts will be needed for the installation of a two-pipe circuit. Nonetheless, the following benefits outweigh the expenses and difficulty of the work:

• the ability to connect the "warm floor" system;
• uniform distribution of heated coolant over all heating devices;
• installation of regulatory reinforcement, both on the strapping of radiators and on separate contours.

Both forced and natural circulation two-pipe systems are separated into communications based on how the work environment is moved. First-type networks are used to arrange spaces up to 400 square meters in size in private homes. A specific coolant transportation speed should be guaranteed by the pipe diameter. The heating system calculation is performed in order to select the appropriate pipeline section. An expansion tank, positioned at the highest point, should be included in networks with upper wiring and natural circulation. The tank body needs to be insulated because it is typically located in the attic.

There are two methods for achieving forced circulation in the heating network with upper wiring. In the first scenario, the reverse line’s direct section has a membrane tank and a circulation pump installed in the pipeline. These kinds of heating networks are used to heat private homes, so radiators made of cast iron or aluminum can be used to install them. It is important to keep an eye on the coolant composition when installing aluminum models. High pressure on the network provides circulation in multi-story buildings with central heating. In order to maintain continuous and extended communication, batteries that can withstand hydraulic shocks are chosen.

A wide range of radiators appropriate for the installation of systems with various upper wiring types can be found in TM OGINT’s product list. You can efficiently use thermal energy and regulate its consumption with the help of regulatory reinforcement and shut-off pipeline equipment.

Multi -apartment building heating system

Projects led to the creation of centralized heating systems. As a result, if you locate the project and read it through to the very end, you can learn absolutely everything there is to know about the heating of the apartment and the entire house.

Next, we look at which are typically utilized for apartment building heating and how they impact apartment heating quality. Additionally, as is also the case in reality, problems with pipes, batteries, and the high-altitude apartment building’s entire central heating system are fixed.

Why is the heating circuit of a high -rise building is interested in

A multi-story building’s heating system may cause concern in a number of situations, including:

• When replacing the radiator in the apartment, the question arises – how to turn off the riser, which radiator can be put and what is the best ..
• If you change the riser, what pipes can be used?
• When heating works poorly, it is natural to ask why? – Maybe you can adjust, even yourself ..
• If there is a desire to organize your boiler room together with other residents, then how to do it ..
• When installing a heat meter, in which place the system is placed?

However, there would be no central heating action without ZhEK approval. And typically only experts from the same service company carry out such tasks.

What schemes are found in apartment buildings

Individual projects that use the central heat station to heat entire regions are contingent upon the availability of available housing. Although it wasn’t always the case, they constructed both tiny boiler houses and very large TPPs. Usually, one boiler room had one microdistrict.

However, the heating of high-rise structures constructed during the Soviet era is typically typical. When a vertical riser consisted of just one pipe, single-pipe connection diagrams were employed. Many houses had risers, which were placed roughly in the same hydraulic conditions since they were connected in parallel to the heat-magistraul for transfer.

The figure depicts the general layout of the vertical one-pipe. We need to be aware that up to 18 radiators can be connected to a single pipe.

The proper parallel-bypass circuits for connecting radiators.

The apartment’s radiator connection diagram uses a single-pipe wiring system throughout the house.

Because there are bypas available, turning off one radiator (which is still flowing!) won’t affect the heating in other apartments. You can also mute the radiator whenever you want thanks to the balancing valve.

However, one known drawback is that the final radiators in the ring have a lower temperature, which causes muds. How did they battle over this?

Features of heating in apartment buildings

The riser, which equalizes the temperature at the supply and return, should be used to determine the high speed of the coolant in order to prevent the radiators on the lower floors from being overly cold. They knew how to set up centralized heating systems so that users would not notice a significant difference in the riser’s temperature. Furthermore, no one fought when the radiator area was raised in line with the direction of heat transfer.

• The centralized heating system is characterized by a high speed of the coolant – to the limit of noise in the pipes. Hence the high power of the pumps and a large pressure drop.
• The second feature is a large general pressure in the system. Filling was carried out from the lower point, and in order to raise the coolant to the 9th floor, it was necessary to create appropriate pressure, up to 12 atm.
• The next feature is the high temperature of the coolant – poor thermal insulation, heat leaks, the unexpected energy of the energy resource, often allowed the communalists to solve the tasks “heat in the houses” by simply wrapping the flow rate and inflating the temperature above the norm, even higher than 100 degrees with increased pressure with increased pressure from increased pressure.

This creates the needs for pipes and radiators.

What pipes and radiators to use in a multi -storey building

During the Soviet era, cast iron radiators and steel pipes were installed in every high-rise structure. There’s an option now. Alternative pipe and radiator types are more affordable, practical, and long-lasting.

However, it is unacceptable for them to replace the apartment’s radiator on their own without consulting the housing office first. Even more, only professionals will be able to disassemble the riser and replace the pipes.

Though its maximum temperature is still +95 degrees, the housing specialists essentially solder the foamypropylene RN30 25 mm (external diameter) with aluminum reinforcement. There may be more in the central… at this point, PN25 c similar characteristics have already appeared.

Depending on the service network service’s decision, connecting radiators in a multi-story building may also be accomplished using metal-plastic pipes. The most common diameter is 20 mm (external).

The Zhek staff will have to devise a plan that involves disconnecting two cranes and using a parallel radiator to replace the radiator.

When replacing the radiator in the apartment

• Model, size (heat transfer) of the radiator are consistent with specialists of the service organization.
• The riser is turned off, the liquid is drained.
• Usually old steel pipes are cut, since it is not possible to promote threaded joints. More often radiators change along with pipes, the types of pipes used are also consistent with the housing.
• The radiator is hung on the standard mount, equipped with plugs, ball valves, a crane of Maevsky.
• The radiator is connected to the riser by pipes according to the bypass scheme.

Why is it cold on the upper floors

Reduced coolant speed also results in decreased temperature, which makes homes colder. This is particularly noticeable on upper floors, where radiators are frequently located in the ring. This occurs for both technical and organizational reasons, including enlarging pipes and equipment wear.

The cost of fuel has increased, and it is unclear at what command level it has been tanned, but the end result is remarkable: half of the gas, fuel oil, and vegetable coal go into the furnace. Additionally, the experts in heating systems are asked to "get out" and redistribute the heat by "finding methods." This leads to the replacement of valves, muffleing of the boiler, disconnecting and reconnecting of a portion of the pumps, and the creation of artificial "equipment wear."

Radiators that don’t warm up are another reason why a multi-story building has inadequate heating. Adjustment options are available in any multi-story building’s basement, as any riser will cause the system to overheat due to its intricate design. It’s possible that the network isn’t established because there aren’t enough deserving employees in the company.

However, the only way out of the predicament is through local organizations’ ordeals. or building his boiler room into a small house while cooperating with the authorities. or switch to the apartment’s individual heating system.

Features in new buildings

Currently, a growing number are moving to contemporary heating projects. The energy sector on the movement of the coolant decreases when two muffins are used in the wiring. The apartment’s radiator connection diagram for its two-pipe heating system.

These projects now call for the use of PEX, which is reinforced with aluminum, in place of steel. Radiators with the lower (hidden) eyeliner and a minimum pressure of 16 atm.

The most recent accomplishment is a separate apartment with individual wiring. Two-pipe riser systems are intended for a whole apartment. You can do your own wiring in the apartment, but typically, projects have risers placed in a way that makes it easy to create a radiation scheme from the central manifolds, with the pipes located beneath the false floor.

Installing an intra-fire convector beneath the balcony blocks is now feasible as well. additionally, each apartment has its own heat meter.

However, in the mass of historic structures, this is an apartment building’s central heating system. Profit from what the housing has to offer.

Option of heating installation in a modern apartment of a multi -storey building

• Connecting to the central heating riser (individual boiler) of the heating network of the entire apartment is performed at one point, from which the wiring to the radiators goes.
• Pipes are placed in the floor, the design of which allows you to do this. Radiators with a lower connection are used and intra -sex convectors.
• The radiator switching circuit is preferable, in which only solid pipe segments are placed under the floor – from the central manifold to each heating device.
• In the case of a passing, dead end scheme, all hidden pipe branches can only be performed by crimp non -removable fittings using a branded tool.
• Allowed to hid the installation of fittings and pipes from only one manufacturer. Soldered pipes to hidden installation are not allowed.

Heating scheme of a multi -storey building – how is the supply in the heating system of high -rise buildings

An apartment in a multi -storey building is a city alternative to private houses, and a very large number of people live in apartments. The popularity of city apartments is not strange, because they have everything that a person needs for a comfortable residence: heating, sewage and hot water supply. And if the last two points do not need a special presentation, then the heating scheme of a multi -storey building requires a detailed consideration. From the point of view of design features, a centralized heating system in an apartment building has a number of differences from autonomous structures, which allows it to provide the house with thermal energy in the cold season of the year.

Features of the heating system of apartment buildings

Meeting the standards set forth by the regulatory documents—which comprise SNiP and GOST—is imperative when installing heating in multi-story buildings. According to these documents, the heating system should keep the apartments’ temperatures between 20 and 22 degrees Celsius, with humidity levels ranging from 30 to 45 percent.

Even with norms in place, a lot of homes—particularly older ones—do not match these markers. If this is the case, you should install thermal insulation and replace your heating equipment before contacting the heat supply company. One example of a well-designed heating circuit is the heating system of the three-story building, whose layout is shown in the picture.

High-quality equipment is needed for a complex design in order to achieve the required parameters. When designing a project for an apartment building’s heating system, experts apply all of their knowledge to produce comparable pressure on each floor of the building and uniform heat distribution throughout the heating main. Work on an overheated coolant, which enables a heating scheme for a three-story building or other heights, is one of the essential components of this design.

How does it operate? Water that has been heated to 130–150 degrees is delivered straight from the CHP. Furthermore, the pressure is raised to 6–10 atmospheres, which prevents the formation of steam and ensures that water is driven on all floors of the house without any losses. In this instance, the fluid temperature in the reverse pipeline can reach 60 to 70 degrees. Naturally, because the temperature regime is directly related to the outside air temperature, it may vary throughout the year.

Purpose and principle of operation of the elevator node

As mentioned earlier, a multi-story building’s heating system heats its water to 130 degrees. However, regardless of the number of stories, this temperature does not require consumers, and heating the batteries to such a value is completely useless. In this instance, the nine-story building’s heating system will be identical to any other. Everything is very clearly explained: in multi-story buildings, the heating supply terminates at an elevator node, a device that reverses its outline. What does this node mean, and what are the functions that it serves?

After being heated to a high temperature, the coolant enters the elevator node, which functions similarly to an injector-submarine in theory. The liquid then transfers heat following this process. After exiting the elevator nozzle, the high-pressure coolant passes through the reverse highway.

Furthermore, the liquid enters the heating system’s recirculation system via the same channel. When you combine all of these procedures, the coolant reaches its ideal temperature and can be used to heat every apartment. No matter how many stories a building has, you can guarantee the best heating possible in high-rise buildings by incorporating an elevator node into the system.

Design features of the heating scheme

Additional components, like collectors, heat meters for batteries, and other equipment, are frequently utilized in modern buildings. To reduce human involvement in the design process, nearly all high-rise building heating systems have been automated recently (see "weather-dependent automation of heating systems – about automation and controllers for boilers with examples"). With the help of all the information provided, you can improve performance, boost efficiency, and distribute thermal energy more fairly throughout each apartment.

Pipeline wiring in a multi -storey building

Multi-story buildings typically use a single-pipe wiring scheme with an upper or lower outlet. There are numerous variables that can affect the placement of the straight and reverse pipes, including the area in which the building is situated. A five-story building’s heating system, for instance, will constructively differ from a three-story building’s heating system.

All of these elements are considered when designing the heating system, and the best plan is developed to maximize each parameter. The project may assume that the coolant is externalized from the bottom up or the opposite. Individual homes are equipped with universal risers, which guarantee the coolant will always move.

For the sake of comfort and energy conservation, it is critical that apartment buildings with upper wiring have adequate insulation and heating. We have explored the complexities of these systems throughout this article, comprehending their elements, difficulties, and solutions.

The effectiveness of the heating system is primarily dependent on its design. For even heat distribution with upper wiring, where pipes run along each floor’s ceiling, a carefully planned layout is crucial. To stop heat loss and preserve efficiency, proper insulation must surround these pipes.

The system’s performance is also significantly impacted by the heating source selection. Every alternative energy source, such as heat pumps, individual boilers, or central heating, has advantages and disadvantages. Careful consideration must be given to factors like cost, energy efficiency, and environmental impact.

Insulation is essential for maintaining heat inside the building in addition to the actual heating system. Walls, floors, and roofs that are properly insulated help to reduce heat loss, which lessens the strain on the heating system and, in turn, lowers energy bills. Purchasing premium insulation materials and making sure they are installed correctly are essential steps in this process.

To maintain the heating system operating efficiently, regular maintenance and upkeep are also necessary. Regular inspections for leaks, malfunctions, or inefficiencies can help find problems early on and fix them to preserve system longevity and optimal performance.

All things considered, appropriate heating sources, careful maintenance, good insulation, and well-thought-out design are needed to achieve efficient heating and insulation in apartment buildings with upper wiring. Residents can enjoy a comfortable living environment and help with energy conservation and long-term cost reduction by putting these strategies into practice.
