How to repair, hide and maintain the heating riser
One of the remnants of the Soviet era, you can constantly watch in his apartment - bulging and spoiling the interior of their kind of metal riser heating wiring. Why exactly did the designers decide to make the system?
It was probably easy and cheap, as well as fast, because very few people were worried about the interior of the rooms at that time. Now, many homeowners are solving for themselves the problem of how to hide the heating riser so that it does not spoil the exterior of the room.
This article will answer other important questions related to heating the apartment. In particular, what is the riser heating system, how is it being repaired and balanced?
Layout
The riser is a vertically installed pipe that combines several heating radiators into a single circuit. It is made most often from metal or polypropylene. Risers can be combined in pairs or be independent of each other.
Below we consider both cases in more detail:
| Bottom | The lower distribution of pipes is called classical two-pipe. In the basement passes the supply and return, and the radiators are connected to the jumper between them. Two risers are interconnected in the attic of the house or its upper floor. According to the rules of such a connection, the heating risers must be balanced passability of the near to the lintel of the risers is limited, so that the long-distance ones can work effectively. However, neither the throttles nor the thermostats in the basement do not put, although the temperature variation between the apartments is small. This is due to the fact that:

Tip: jumper installed in the attic, be sure to warm. Otherwise, if the movement of water in the pipelines stops for some reason during severe frost, it will turn into ice. Then, to restart, you will have to use a blowtorch if the riser is metal.
Launch
After the heating tower has been repaired, it is necessary to reset it to make a start.
Let's see how to do everything correctly:
- Upper. Starting heating is not difficult. The instruction is as follows:
- turn off the required riser in the attic, and then in the basement;
- open the reset;
Tip: in order not to make a mistake when turning off the heating in the attic, count the sidebars for bottling, taking the nearest landmark, for example, the exit to the roof or the corner of the building.
- after completing the work, close the reset;
- slowly fill the riser, remembering the direction of water movement in the valves;
- open both taps completely.
It is not necessary to bleed the air, if there is an expansion tank in the attic, where it will be forced out.
- Lower:
- find the necessary valve in the basement and pair it. To do this, we recommend focusing on the position of the radiators relative to the staircase and the flight of stairs;
Tip: do not be lazy, look to the neighbors on the upper floor to make sure how the assembly of the risers is made and the jumper is located.
- open the dumps or unscrew the plugs to reset the risers;
- at the end of the work, close the discharges, and then slowly, so you avoid the water hammer, fill the pipes and radiators with water;
Tip: check if screw valves were installed in the basement, the coolant should follow the arrow on the body. Otherwise, the valve may be torn off, then for repair work it may be necessary to reset the whole house.
- open the valves completely and bleed the upper floor through the Mayevsky valve, which may be at the top of the jumper or in the radiator plug.
Repairs
If you decide to change the site of the riser with your own hands, the work should be treated with special responsibility. When it comes to an apartment building, we recommend inviting a professional team to do this.
In your own home you will need:
- Galvanized steel pipe, the strength of which is quite sufficient. In addition, you will not know what rust is on the inner walls and overgrowing with its deposits.
Tip: when installing galvanizing, it is better to use threads, as during welding work at the site of seam formation from inside the pipe, the protective galvanized layer will be lost.
- Stainless corrugated pipe, which, although somewhat inferior to galvanized mechanical strength due to thin walls, is much easier to work due to flexibility and fittings.
We do not recommend using metal-plastic or plastic pipes in an apartment until the valves are cut off. There is a high probability of water hammer due to improper installation of valves or its malfunction. The pressure of the coolant will simply disrupt them, and it will flood the room. The price of repairs in the apartment and the neighbors will cost a lot of money.
Recommendations of specialists
- Very often, the vertical riser with radiators connected to it and the idler paired to it are located nearby, and their replacement is carried out simultaneously. After repair, the distance between the risers of the heating should give the opportunity to disassemble the fitting or threaded connections on one of them, without disassembling the other.
- Mounting of heating pipes to the wall is not recommended, even if they are made of galvanized pipe. This way you can keep connections from leaking and loosening. Two fasteners are quite enough in the straight section between the floor slabs. For steel pipes, galvanized hose clamps with rubber gaskets are commonly used.
- If you want to disguise the heating pipes, you can hang the curtains from wall to wall. Another option is to assemble a galvanized profile box and sheathe it with wall plastic or MDF panels. We do not recommend completely hiding part of the heating circuit, as the pipes have a limited service life. It is possible that not yours, but the neighbors may leak a pipe, while it is advisable to replace the risers only through the overlap.
- Cut the threads so that at least 80-10 mm remains to the floor and walls. Also, do not cut the pipe before bending it.
- Hold the pipe with the key during threading. So the torque is compensated from the plate so as not to disrupt the thread at the neighbors.
- Lubricate the pipe with engine oil, then it will be easier to work with the die, and it will not leave a teaser.
Conclusion
Heating riser - is one of the main in the distribution of heat to the radiators. It is made of steel or reinforced polypropylene. After its repair, it is necessary to start the heating system.
To mask the pipe in the interior there are several ways - porters, as well as the box. The video in the article will help you find additional information on this topic.
