When you can change the radiators in the apartment

Radiators How not to pour boiling water on the neighbors when replacing the radiators

Usually there is no problem with the number of radiators: they are put in place of the old ones, usually under the windows, to avoid the condensation. However, if the room is big enough or non-standard, it is better to calculate the number of radiators according to the simplified formula: N=S100 W/∆T, in which:

  • N is the number of radiators;
  • S is the total area of the room;
  • ∆T. value of heat output of one radiator (this parameter can be found in the technical data sheet of the product).

This formula is true if the ceiling height is not more than 3 m. Otherwise it is necessary to replace 100 W by 40h (last symbol means height of ceiling in meters). If the region is constantly over 30 degrees of frost in winter, the number of radiators should be increased by 15-20%.

On whose account should the radiators in the apartment be replaced?

Hello, Elena. Replacement and rehabilitating of individual elements and parts of elements of internal systems of central heating, water supply and sewage, hot water supply belong to the current repair. Routine repairs. the responsibility of the tenant. If you carry out a complete replacement of the battery, but not elements (sections), it is the obligation of the landlord (the owner of an apartment), but for this you need to get a written conclusion of the expert (the prescription for replacement). Regulated by the Decree of the State Construction Committee of 27.09.The radiator is to be replaced with a radiator of a different size depending on the size of the apartment (in the apartment building) and the type of ownership.10.2003 N 5176).

Are the radiators common property or is it private property, for which the owner is responsible?

The Government approved Regulation 91 of 13.08.06, which provides a list of property common to the tenants of the apartment building. In this list:

According to this decree, the construction of radiators can be officially considered property of the common use, common property.

But management companies and housing maintenance companies prefer to hide this information. As a result, tenants, apartment owners, when a radiator leaks, try to repair it themselves.

They carry out replacement with a similar or better, improved design. Management companies save on repairs, shifting their responsibilities to consumers.

Rules for disconnecting batteries in winter

To carry out the work the homeowner writes an application in duplicate to the HMO (Housing and Maintenance Office). After the visit to the organization, the applicant’s document should bear the date of admission and a legible signature of the employee who received and registered the appeal. This may be needed in the future, if the case comes to court.

Some tenants do not want to contact the HMO and turn to outside companies. However, you should know that according to the law such works must be agreed with the management of the operating organization. Amateurism is not allowed here.

By installing an additional radiator, you can disrupt the entire heating system, which under the project for each apartment building is calculated separately, including many technical parameters.

  • The power rating;
  • The volume of the heat carrier;
  • The temperature of the working environment;
  • the diameter and length of the pipes;
  • The number of shut-off valves and connected consumers.

Therefore, in addition to permission to carry out the work by the contractor will need a document proving ownership of the housing and the technical passport for the apartment. If the new equipment is acquired by the tenants, to the application shall be attached copies of certificates not only for the radiators, but also for all components: pipes, cutoff valves, fittings.

Who has to change the radiator

Replacement of radiators in the apartment in the winter can be done by the HMO or with the help of a contractor who can be proposed by the owner of the housing or the Managing Company. In any case the service will be paid. An exception is apartments where the tenants live under a lease agreement, but even there the radiator is included in the common property of the house only if there is no shut-off valve on the pipe going from the riser to the heater.

You can also do the replacement yourself if you have experience and the necessary skills. To do this you will need to write an application to the Managing Company or the housing maintenance company about the need to turn off the riser and drain the coolant from it. After completing the work another application for technical expertise is written.

How to get permission

According to Russian law, any activities related to the heating system must be performed by an organization with an appropriate license. The task of the owner. to find such organization or to address in ZhEK with a request for replacement of the battery by the operating organization. This process, as practice shows, is painstaking.

To consider the submitted documents (an application for replacement of the device, copies of certificates of plumbing equipment, certificate of registration of title to housing) sometimes takes up to two months, so you should have patience, and most importantly. to have on hand a registered document, which affixed the date of treatment and is signed by the person who took it. After permission is obtained, you can begin work on. If the Managing Company or the Housing and Communal Company will refuse to issue a permit, you can go to court.

When replacing the battery by an outside company you will need:

  • The application for replacement of the device;
  • Certificate of ownership
  • The technical passport for the apartment;
  • Thermal calculation (when installing additional equipment or increasing the sections);
  • Certificates for the components;
  • Request for technical expertise after the end of the work.

A breakdown happened: who is responsible?

To find the person responsible for the accident, you need to determine who caused it: the property owner or the housing maintenance company. If the owner notices the poor condition of the heating pipes, must immediately notify the staff of the HMO, by calling a specialist.

How to Choose the Most Efficient Boiler | This Old House

It is necessary that the call of the workers was formalized:

  • Application is made, recorded, then assigned a time for repair;
  • After completing the repair of the battery the owner receives an acceptance certificate;
  • The act is signed simultaneously by the landlord and the plumber.

If you follow all the steps, then the responsibility for poor-quality installation of heating devices will be borne by the MC.

Don’t forget! The housing and utilities board is obliged to do regular scheduled inspections of the heating system (at least twice a year) and to repair it.

Based on the results of the inspection, the utility company must issue a final act. When the owners do not let the experts in the apartment, the legislation will be regarded as improper use of communications. The responsibility will fall on the owner.

Who owns the radiators and who pays for repairs

Not all radiators in the apartment are considered to be the property of the residents, so they cannot be replaced without a good reason. The apartment owners are responsible for the pipes that can be dismantled without affecting the heating system in the apartment. In this case the riser pipe branches are equipped with valves or disconnecting devices that do not interrupt the circulation of the heat carrier in the house system. For heating devices of communal property is the responsibility of the managing organization, so if they are corroded, leaky or in an emergency condition, such devices must be repaired or replaced for free.

When choosing new heating devices it is also recommended to ask the managing organization for help. There is information about what parameters the radiators are specified for each apartment in the building.

New radiators will have to meet the characteristics of the heating system foreseen in the technical documentation of the building.

Who should deal with the replacement of heating equipment?

The owner of the apartment can choose one of three options.

  • Independent replacement of radiators (everywhere the radiators are replaced with their own hands, but the law requires membership in the SRO).
  • Applying to outside experts (must be a member of the SRO).
  • Call a master from a service organization.

Despite the fact that employees of private firms can make a better installation of new equipment, knowledgeable people recommend to call a local master. This is so that you know who to turn to in the event of a problem in the future. If an accident should occur, you will not be held liable for any faulty installation that causes damage to the property of other residents.

In the current legislation there is no ban on changing the radiators during the heating season. However, you will have to agree with the management company to turn off the heating throughout the house. You need to get their permission.

Replacing radiators in the winter and fall will cost significantly more than at other times of the year. And management companies agree to approve applications for the procedure only if the work will be done by their plumber. Monopolization of the service allows management companies to dictate prices.

Radiators: How not to pour boiling water on the neighbors when replacing the radiators

The reasons for replacing the radiators can be different. Sometimes. it is a necessity: say, a redevelopment, and you need to move the radiator to another wall. Sometimes it is an emergency leak, and then you have to change the radiator in an emergency in order not to flood the neighbors. Sometimes the replacement of the radiators is a preventive measure: if you do a capital repair you can replace all the pipes at the same time. And how do you know when it’s time to change the radiator?? What rules to follow when changing? Whether it is possible to change batteries in the summer or it is better to do it in the winter? In general, is it worth changing the old batteries for the new ones, if apart from their age there are no claims to them??

The most common situation. the battery is cold or slightly warm when it should “heat” properly, there is condensation on the windows, and the house is damp. It can be connected with a lack of water temperature in the heating system, with an air lock or a prosaic clog in the pipes.

If you have central heating check whether all the radiators and pipes in the apartment are not warm. If the temperature of all parts of the heating is the same, but not higher than 30-40 degrees (warm, but the hand tolerates), listen to the movement of water through the pipes. If there is a sound, it means the water is moving. Then the boiler room or the boiler can not cope at the moment, and pumps are driving a little warm water through the pipes. Call and find out.

If the pipes are quiet it could be an air lock. It can interfere even when the boiler room “gives boiling water”. If the neighbors on the side are fine, the problem is in your riser. the system of pipes of your apartment, the neighbors below and above. If you have an upper floor, your radiators are the highest point in the system and can have bleeder valves on them. As a rule, the people on the top floor, who are the first to freeze, do the bleeding themselves.

Clogged or damaged pipes and valves are a more serious problem. Places of failure are determined by examining the temperature distribution of the pipes. Either way you will need a locksmith with specialized equipment.

When it is time to change the radiatorsIf you have old cast iron radiators in your apartment, which were made many years ago by other standards, it’s definitely time to change. The service life of cast iron radiators is 25 years, and it is likely that it has long expired. Just to be sure: touch the bottom of the radiator in winter. it will most likely be just barely warm. It’s not the boiler house’s fault, it’s just that the cast iron radiators are clogged with limescale and need to be replaced.

It is likely that the radiators need to be changed when you move into a new apartment. Small plate or tubular radiators (convectors) that are installed in new buildings are much worse in heat dissipation parameters than radiators of other systems.

At

Buying an apartment in a new building, in most cases the buyer gets ugly piping to the radiators right on the floor. Whether to change the radiators in the new building is up to you to decide, but most of our customers insist on the replacement themselves. It is important to understand that the radiators are changed at the very beginning of the repair: decide at once and put this point in the estimate if necessary.

As part of the project, we provide the repair team with technical data, accordingly, we select heating devices for a particular apartment. Many customers first choose with their hearts. they ask for beautiful and “eternal” radiators made of cast iron: on legs, with an ornate pattern. Unfortunately, their technical characteristics are not suitable for all apartments in apartment buildings. We have to dissuade and explain.

To

What happens to the radiators at the end of the heating seasonIn brief, what should not be. If there are no visible traces of corrosion or cracks on the radiator, valves are not broken and it does not leak, it is impossible to check its serviceability by yourself.

At the end of the heating season, all heating systems are filled with water at maximum operating pressure. This is done in order to prevent accelerated corrosion. But a month after the end of the season and the closing of the valves in the boiler rooms under pressure, many heating systems become empty. Usually it is due to the negligence of utilities. gate valves in the input and riser pipes are not closed properly. Almost every house has a leak in the basement. In addition, in summer, many tenants move or increase the battery: that is, they flush their riser, and all the neighboring through it descend by the law of communicating vessels.

In theory, the water must remain in the system, but in fact it is not there by late spring. The only exception is in houses where maintenance is done properly, but they are very few.

When it is better to change the radiators in the apartment: in spring, summer or fall

“In summer to change is better, because you do not need to turn off the heating standpipes and drain the water, “- something like this the vast majority of people think. However, this is not entirely true. In summer, there is water in the riser pipe, and leave it there so that the pipes do not “overgrow” rust. Whether there is water in the pipes or not. can only know the chief engineer in the HOA or the management company. Advice: Tell the service in advance when you need to have the water drained. Set aside a few days (a little longer than necessary) to replace the batteries, so that unforeseen delays do not interfere.

Do they change the radiators during the heating seasonThe main advantage of doing the work in the summer is that it is very easy to agree to drain the water. But there is no more pluses. A client of mine had a ruptured new radiator in autumn when the owners were out of town. Only because they couldn’t check the quality: they can’t get pressurized water in the riser pipes in the summer. This means that the quality of work performed and the level of heating of the radiator can be checked only after a few months (certainly not before the 20s of September).

In the heating period risers are always filled with coolant. And in order to carry out the work, you need to negotiate with the HOUSE or a housing company to turn off risers. It is as easy to do as in the summer. contact the chief engineer by phone or with a statement on paper. And then you immediately at the end of the work check the quality of welding and threaded connections.

Choosing the type and model of the new radiator.

Now let’s analyze in detail the radiators on the market. For installation in apartment buildings, bimetallic, tubular steel and cast iron radiators are suitable in their scope of application.

Features of cast iron radiators.

Cast iron radiators are used only in low-rise houses. Where the heating system works under relatively low pressure. That is why you will never find cast iron radiators from builders in houses higher than 9 floors. This is due to the fragility of cast iron. Also, cast iron radiators have too rough a surface treatment in comparison with bimetallic, this also applies to modern models.

Steel and bimetallic radiators.

The most suitable types of radiators for central heating in apartment buildings can be called bimetallic and tubular steel. The latter are relatively rare in the Russian market, but this does not affect their attractiveness, but only their price. The most popular steel tubular radiator on the Russian market is Arbonia. But I’ll tell you a secret. Russian manufacturers RadStal have learned to make an exact copy of these radiators and they cost 2 times cheaper than the German ones. The main advantage of steel tubular radiators over bimetallic I would point out acoustic comfort. It happens seldom but well. When a bimetallic radiator can make noise.

Choosing a bimetallic radiator.

Let’s take a closer look at bimetallic, as the most common. As experience shows the study of the radiator market, and I do not have a small one, not always if the manufacturer specifies that the radiator is bimetallic, it is suitable for central heating systems. Manufacturers very often skimp on the manufacturing process and perform the so-called pseudo-bimetal. That is, only vertical collectors are bimetallic (steel inside, aluminum outside), and the horizontal collector is made entirely of aluminum, which in contact with the coolant is corroded. Confirmed by the repeated treatment of customers in my store after 2-3 years. This applies to such models as Rifar Base, Rifar Forza and Sira Gladiator.

All remaining bimetallic radiators I would divide into 4 groups:

Poor quality radiators are radiators made under unknown brands, usually in China. At a cost they usually fall within the range of 300-500r per section. The disadvantage is the low quality of painting. The paint comes right off when installed. In the future peeling at the edges.

To the second group I would classify all well-known Italian manufacturers. Such as Global and Sira. The disadvantage of which are too narrow vertical collectors. In a system with a heat exchanger will work fine. And in the house where the coolant is fed to the radiator, can not work very long and get clogged with scale.

Among the quality ones I would classify Royal Thermo and Bram.

The best and only bimetallic radiators on the market with an all-welded manifold Rifar Monolit and Rifar Supremo.
