Is it possible to increase the radiators in the apartment?

How to add sections to a bimetallic radiator. Connection methods and the maximum number of sections.

When new bimetal heating batteries are installed, but it is still cool in the room, it means that the calculations of their capacity were incorrect. As a rule, this happens if the calculations were made only for the area of the room, without taking into account all the heat loss in it. It is necessary to know exactly how many sections of a bimetallic radiator are required to create a truly comfortable environment for living.

In the case where there were errors in the calculations, you can correct them by adding a section or more to an already installed structure.

How to add sections to the heating battery

In order not to start a time-consuming and expensive procedure to reconstruct the entire heating system, usually resort to another course of action. to screw on additional sections. This work is not very complicated, so it is often done by the owners of the houses. It is important to understand how to connect heating radiators with each other correctly. The main thing. to study well the technology, how to increase the heating batteries. This will ensure that the procedure will be carried out qualitatively and quickly.

Aluminum radiators

Adding sections to the cast iron radiators is more complicated process than, for example, extending the aluminum heating radiator. But here you also need to know how to correctly augment aluminum radiators to make the room warmer.

The aluminum radiators are made in the same way as the cast iron radiators. True, here you do not need to use remarkable strength, disassembling the radiator. The sequence of operations when increasing the additional sections in the aluminum radiator is as follows:

Extend aluminum radiators is simple enough. You can do all the work yourself. The most important thing is not to mix up the threads on the nipple.


How to change the central heating batteries in the apartment

With the approach of the new heating season is again becoming relevant issue of heating apartments. To be thoroughly prepared for the coming cold weather, many people change radiators for a better model. The observer of RIAMO in Podolsk found out who has to pay for repairs and what to do in case of a leak.

Who should pay for replacing the radiators?

According to the Housing Code, in privatized apartments the walls, roof and transit utilities (including batteries) are the common property of the apartment. Therefore, the management company is responsible for their condition, and homeowners are not obliged to pay for the replacement of worn-out radiators. However, the radiator is not considered common property if it can be separated from the riser pipe with a locking device.

Before replacing the batteries, you need to check whether there is a tap on the branch from the riser of the in-house heating system to turn off the batteries. If it is not available, you can apply to the management company for free replacement of radiators. Owners can also collectively decide to replace the batteries for an additional fee, such a condition is usually specified in the management contract.

A tenant renting accommodation from the state falls under the Rules of maintenance of the common property in an apartment house, where the common property also includes the internal house heating system, including risers, heating elements and stop valves that regulate them, as well as other equipment in these networks. Therefore repairs and replacement of batteries must be paid for by the management company from the funds accrued under the item Current repairs and houses, except for work performed within the framework of capital repairs of the heating system of the house as a whole.

If the radiator does not have a turn-off valve, tenants do not have to pay for the purchase of a radiator and its replacement. If so, replacement of radiators in the apartment will be considered a running repair, but according to the Social Landlord’s tenancy agreement it will be done at the expense of the renter. Thus, the tenant is obligated to monitor the serviceability and safety of the equipment inside the apartment and to make current repairs of the premises at his own expense.

Legal peculiarities

The law limits the tenant or the apartment owner’s possibilities to replace the radiators by himself. According to articles 44 and 46 of the Housing Code, the radiator as part of the common property can only be replaced by a decision of all homeowners at a general meeting. Otherwise, the replacement of pipes and radiators in the apartment will be considered as an unauthorized use of property, and the rules violator will be held personally responsible in case of an accident in the heating system.

The HOA requires agreement with them to install an additional heating element in the apartment or change its configuration. Such actions are considered to be a re-equipment of the heating system, so the corresponding notes should be made in the technical passport of the premise. In most cases, the replacement of the battery is not reflected in the technical passport.

Reasons for replacing the radiators

According to current standards the lifetime of cast iron batteries is 15-30 years (open heating systems) and 30-40 years (closed systems). Replacing the radiators belongs to the category of major repairs.

Replacement of heating radiators through the Managing Company is possible only if the heating devices are out of order and their operation time has been exceeded. In all other situations, the maintenance company performs only minor repairs.

The radiators in the apartment should be replaced if possible in the summer or before the heating comes on. However, in this case you can not immediately check how well the work is done. If the heating is turned on suddenly and the apartment owner is not home, the system can leak, and it will take a lot of effort to fix the consequences.

Replacing the batteries during the heating turn-on period is complicated by the fact that during the work you will have to turn off the heat in all apartments, connected by the same riser. But this is only if the radiators in the apartment are not turned off by the tap.

If the central heating radiators in the apartment need to be replaced and there is no jumper, you can write an official letter to the servicing company with a demand to change the radiators in two copies, and ask to make a note of registration on one of them. Make sure that there is an incoming number, date and a legible signature of the person who received the application. You can also send a registered letter by certified mail with notification.

Applications for the replacement of heating devices and the disconnection of the riser and the removal of water should be submitted to the management company. If the first application is submitted in order to get approval in principle for the replacement and to determine the timing, the second is directly to perform the work.

If the management company does not want to change the radiators

It is worth reminding the representatives of the Managing Company that if the radiator breaks, the servicing company will be responsible for compensating the material damage.

The management company in response to a request to replace the central heating radiators in the apartment can refer to the paragraph about the balance division of joint and private property, according to which the owner is responsible for the repair and maintenance of the radiators. But contradictions in the law do not cancel the main provision, which refers heating radiators to the common property. You need to be ready to the fact that you will have to defend your case in court.

How to change the batteries yourself

Number of heating devices: one section should be per 2 square meters of housing and additionally one section for the entire area of the room.

Quantity of heat necessary to heat the room: 34 watts of thermal energy per 1 cubic meter in a brick house, 41 watts in a panel house, 20 watts in a new construction. Based on this, the required amount of heat for the room is determined.

Mainly install steel and cast iron radiators, which are suitable for central heating of multi-storey houses. The material has a high heat output, resistant to temperature and pressure fluctuations, as well as aggressive environment. Relatively recently bimetallic radiators appeared on the market, which do not differ practically from the monometallic heating devices, but they are more attractive in appearance.

If you replace the radiators in the apartment yourself, as well as when they are moved to another place, you should inform the building service organization.

If the replacement is carried out on similar structures, simply provide information about the upcoming installation work.

Radiators of a different model will be installed, which may lead to an increase in the heating area? Representatives of the management company will perform an expertise to find out whether there is a possibility of changes in the heat balance of the building. The master will inspect the area of the house, the new batteries, examine their technical data.

Examination is also performed in the case where the overhaul of the apartment involves a change in the configuration of the pipeline.

According to the law, the additional installation of heating devices must be agreed with the administration of the operating organization. As the heating system is calculated individually for each house (the number of devices connected, temperature and volume of the coolant, the nominal capacity), if you do not agree with the work can reduce the quality of heating.

To obtain permission for replacement must write an application, attach technical passport for an apartment and a certificate of ownership, heat calculation of new heating elements, certificates of conformity for all components (valves, pipes, fittings, radiators, etc.).

The review of documents and the issuance of permits can take 2 months. You will also need to additionally write a statement about the need to drain the pipelines and disconnect the riser. After the replacement of heating radiators, it will be necessary to write an application for technical expertise.

First do the dismantling of the old radiator. To do this, you need to unscrew the threaded joint or cut the weld with an angle grinder. Next, the fitting and overhang of the new heater is performed. It is important to correctly align vertically and horizontally, exclude possible misalignments and other defects.

To properly replace the radiators of heating in the apartment, you need to use a construction level. For quality and maximum efficiency of the system it is necessary to prepare ball valves, plugs, Maevsky cocks and installation of bypasses. Using special tools is carried out threading the riser when connecting the battery to the riser.

To avoid the rupture of the heater and water hammer during the pressure test, the bleeder valve and all shut-off valves must be closed. Wait till the coolant fills the system and the pipes become hot. After that you should slowly open the valves, carefully unscrew the head of the air valve and keep it open until the water. This means that the radiator is completely filled with water and there is no air lock. As soon as water appears, close the valve.

Typically, such work is performed for a fee by employees of the Managing Company under a separate contract.

How to Fix One Radiator Not Working. Plumbing Tips

If during the heating season one or more batteries have a leak, it is a pre-emergency situation, as the water is in the system under pressure, which is fraught with flooding the apartment along the riser.

Upon detection of a leak, the owner of the apartment should not waste a minute and notify the service organization. Managing Company, HOA, housing and communal services or other service company must respond immediately and eliminate the problem, preventing a larger-scale accident.

After that the managing company must replace the leaking radiator with a new one.

How to choose a radiator?

Tell about the existing advantages and disadvantages, we will try to give a complete answer in which cases it is recommended to use a particular type of radiator.

How to install a radiator correctly

Throughout the series of previous articles we have tried our best to dissuade readers from installing heating radiators with their own hands. And not only because it is a troublesome business, requires skill, skill to handle the tool, to understand the device inside the house communications.

But also because a poorly installed radiator is a pain not only for the owner, but also for the neighbors: leaks, air s, horrible noises at night. The more so that to install a radiator the price is quite reasonable: 2.4-4.5 thousand euros. for one radiator.

Consider what is easier for you: to earn that money, or to make the connection of the radiator heating with your own hands.

How to effectively increase the heat output of the central heating battery?

Centralized heating system consists in heating up the coolant in a boiler room and its further distribution in the living space with a system of pipes and radiators. In order to heat as efficiently and evenly as possible, you need to choose the right radiators, as well as take additional measures to increase the heat output.

In the long term, knowing how to increase the heat output of the central heating battery, will help the owner to achieve the maximum comfortable and smooth heating of their home, and permanently solve the problem of cold in the apartment with the heating system on.

Expanding and transferring heating radiators

The boiler room is smoking from the heat, but it is still cold in the house? What is the reason for this situation? Perhaps your cast iron batteries simply can not cope with the load, which increases especially during hard frosts? How to increase the efficiency of the heating radiator? In this case, there is a solution. to transfer the radiators and increase their. After all, it is not necessary to replace the radiators, you can simply move them to a more optimal environment and increase the missing number of sections.

Preparatory work

The horizontal size of the battery will increase, so before you connect the extra section to the radiator, you need to pre-mark the extension of the body and redo the connection socket on the drain side of the heater.

If the supply and exhaust are made of heat-resistant polypropylene pipe, it will be enough to solder an additional piece with an angle. The final soldering into the drainage circuit of the heating system can be done not before the additional section will be connected.

How to connect the two sections

Before assembly the plugs and drain cock are unscrewed from the upper and lower channel. To make sure it is the right choice, before connecting the sections, you need to check the integrity of the threads. To do this we simply screw in the nipples of the purchased set to the edge or the notched groove.

Nipple with a gasket to screw in a third of the thread

When rotating the nipple, the two sections of the radiator are fed towards each other and tightly squeeze the sealing ring. To reassemble it is necessary to rewind the seal, install the gasket, tighten the nipples and try to put the new register on the threads from the opposite end. And it is necessary to put on two nipples at the same time and try to do without twists, otherwise you can not connect the two parts safely. The old battery and the section should be located in one plane, on one axis.

When screwing in the nipple with a wrench the battery parts close together

Then using a wrench with a wrench turn the threaded adapters, making 1-1,5 turns on each side. If casings are successfully connected without a deflection, then next sections are installed and on the last wall a valve and a plug are screwed in.
