Replacing the heating system in an apartment building. Rules for replacing heating pipes: selection of materials and installation Repair and replacement of heating: which work is ordered more often

With this topic I would like to make life easier for potential customers who, for various reasons, have decided to replace the heating appliances in their apartment. To begin with, I would like to indicate the level of my competence, so that I can understand that my opinion can be trusted. Education: Moscow State University of Civil Engineering, Faculty of Industrial and Civil Engineering, 2008-2010. management retail stores plumbing supplies (2 stores in the Moscow region, Solnechnogorsk).

From 2010 to the present day, I have been installing heating and water supply systems personally, and also, as a foreman, I have been renovating turnkey apartments, my main activity being replacing radiators using welding. It’s difficult for me to say exactly how many radiators I have already replaced in apartments over 7 years of personal installation (about several thousand, 3, 4, or 5) is not so important, what matters is that this moment I do not know of a single case at my facilities of a leaking or non-heating radiator, either in whole or in part. (ugh, ugh, as they say...)

So, let's start, first let's look at the simplest case, when radiators need to be replaced during an apartment renovation. It is best to replace radiators at the stage of finishing the rough finishing, that is, when the walls have been plastered and the screed has been poured. It often happens that an old radiator prevents you from plastering the wall behind it, in which case you need to plaster wherever possible around the old radiator, so that the radiator installer understands at what level the wall is and installs the radiator both at the required distance from the wall and in parallel her, and plaster the space behind the radiator by removing the new radiator after installation. You should also understand the technological process that first the radiator is installed on the brackets, blanks of new bends are attached to it on the union nut of the ball valve, and only then the bends are welded to the riser. And not vice versa. The reason is the need for clear alignment of radiator outlets and collectors. An example of a job I re-did where the process was not followed.

The best time of year when it is worth replacing radiators is March-April, the heating season is still in progress, that is, after installation the system can be pressurized, but it is already warm outside and therefore residents of apartments located on the riser will not have time to experience the discomfort of being turned off for an hour. two risers, however, this does not apply to particularly nervous segments of the population who sit at home and at the first symptoms of cold batteries call local authorities, but we will not focus on a particular case... If the house is a new building, then they usually have the possibility of pressure testing all year round, so in new buildings there is no difference when to carry out installation during the year. And summer will be the best time.

I think the most inappropriate time is September, simply because everyone who wanted to replace the heating radiators was dragging their feet until the last minute and before the start of the heating season they decided that there was nowhere else to delay. This is what the practice of all years of my work without exception shows, while during the year there is a calm work, without fuss and panic, the customer after contacting within a week can receive the service provided, then in September, as a rule, you will have to wait 2-3 weeks and the opportunity There will be no way to reschedule the installation day, or you may not even have to wait at all, as was the case this year, for example, the heating season began on the 20th of September, and the management companies send everyone who did not have time to replace the radiators to the spring, refusing to drain the risers. I perfectly understand the management of management companies who are afraid to create headache out of the blue from calls from bored old women to the council, because not all installers can replace radiators both quickly and efficiently. And during the heating season there simply won’t be time to calmly correct the shortcomings...

I also often come across a situation where the renovation of an apartment has already been completed, but the heating radiators need to be replaced. This happens because of the builders’ hopes for radiators, who, with the onset of frost, did not live up to their hopes, either because the management company refused to drain the risers during the heating season, and the house was surrendered in the winter, or, for example, for some reason, repairs began in the winter. Of course, you can replace radiators by welding without damaging the finish in a renovated apartment, but it is important to understand that there will be space under the window behind the old radiator with an unplastered wall and no wallpaper. Of course, you can glue the wallpaper later and plaster the wall, but it won’t be as neat as if you did each stage of finishing in its own time.

Now let's look at the choice of editing performers. I think that the replacement heating radiators can only be entrusted to highly specialized specialists. That is, for those who only replace radiators. Why exactly - about this in detail. Apartment owners very often take the simplest route and turn to those specialists who service the house. But unfortunately, not for me, of course) the employees of the management company do not have the skills and the necessary specialized tools to carry out such work efficiently, and also, to everyone’s regret and surprise, they do not have the knowledge to perform the installation in such a way that the radiator is completely warmed up. Perhaps I will surprise someone, but I have not yet met a single mechanic from the management company who has seen the lower bimetal connection for the second time in his life. Only the first one. And that’s when I decided to check my work before starting the risers and went into the apartment. Although the instructions for any bimetallic radiator indicate that the return flow (cooled coolant) should come out of the lower manifold.

As for the tools, here in the management company the situation is just as sad; mechanics servicing houses do not have the opportunity to have a set of the necessary expensive tools for high-quality installation, as this should be ideal.

A separate song, familiar to many first-hand, is the special accuracy of CC mechanics, but this is a matter for each mechanic personally and we will not focus on this. It is also worth noting that it is very dangerous to trust the installation of radiators to finishing teams performing turnkey repairs, regardless of their nationality. As for the choice of pipe material, if your heating risers are made of steel, then only gas-welded steel should be used and bends to the radiator should be made for reasons of reliability and aesthetics. Let's look at the materials in order. Most often, this rule is violated by installers who perform installation using polypropylene pipes. But not many people know, if anyone knows at all, that the installation of high-temperature heating systems in apartment buildings with polypropylene pipes in accordance with GOST R 52134-2003 is simply prohibited. According to Table 26 in this GOST, heating pipes in apartment buildings must be kept in emergency mode at 100 degrees Celsius for 100 hours at a pressure of 10 bar; at one time, if you look at the marking of any polypropylene pipe, it indicates the maximum operating temperature - 95 degrees Celsius . If for someone the words of the ZhEK mechanic that we don’t have such temperatures and never will be the ultimate truth, then you should understand what the words of an employee not supported by contractual obligations will mean and your own life and health? If it’s hard to imagine, then I’ll tell you, these words will mean absolutely nothing; in the event of an accident with serious consequences, you will not be able to hold anyone accountable, even if you can physically find the performer, which is also not a fact...

Installation of radiators using pipes and polypropylene. before and after:

In order for thoughts about installing a pipeline made of any polymer carrying almost boiling water under pressure in your apartment to disappear forever, you just have to imagine what a leak in a polymer pipeline looks like in reality. If a metal pipe at the site of a leak first drips, and only then produces a fistula (thin stream), which, even if it slightly damages the finish, certainly does not threaten health and life, then plastic pipe tears along the seam or with a significant hole. You can relatively calmly leave the room and, having called the emergency service, also relatively calmly wait for the emergency team. But when there is a polymer breakthrough, the only task will be to carry your feet away faster... I have never observed a polymer pipeline breakthrough in reality, simply because I work with steel pipes, I only once felt 6 atmospheres from a riser that I cut with a reciprocating saw at the command of a mechanic from the zhek. Unfortunately, the taps were not kept on the riser, and while the mechanic realized that it was time to “cut down” the whole house, I was holding a clamp of rags on the riser for about 40 minutes, wet from head to toe, while the customer and his partner collected water with buckets and rags... We got away only a slight fright, because it was summer and it was in a new building, the water was not hot, and the apartment below was not yet occupied and not renovated. Also, as a child, I saw a breakthrough steel pipe heating in the apartment, nothing too bad, I heard a quiet hissing from the next room... I went in to look and was a little surprised, but nothing threatened my life... But the break in the polymer pipeline does not look so calm - Publication in the online newspaper Bryansk.ru So with the material we kind of figured out what they should be metal pipes. But there are different metals). In addition to black steel pipes for welding, copper pipes are also common on the market, and inside the Moscow Ring Road there is a chance to find an installer with the skills and tools for installing stainless pipes under a press. Concerning copper pipes, it is worth noting that they have a very thin wall, namely 1 mm versus 2.8 mm for steel pipes, and copper is also a relatively soft metal, so it is not advisable to use them in central heating systems due to the risk of abrasion from the inside from dirty coolant, and there is no clean coolant in Russia ) As for stainless steel for press, in the absence of any advantages in reliability and aesthetics, stainless steel for press turns out to be very unprofitable due to high cost fittings. For example, 2 couplings 22x3/4″ HP, 2 tees 22x15x22 and 2 corners 22x3/4″ HP without taking into account the cost of installation will cost more than the cost of installing a radiator by welding, which only contains a black pipe at 100-140 rubles per linear meter.

As for aesthetics, I was lucky enough to somehow redo the installation of stainless steel under a press, details in the photo:

Now let's take a closer look at steel pipes. As it turns out, there are also options here, namely by type of connection and type of welding. As for the threaded connection, the main disadvantage is the presence of vulnerability in the presence of bends, without which not a single threaded installation can do. The drive is a detachable connection on a cylindrical thread using a lock nut. The vulnerability lies in the too thin metal wall on a cylindrical thread compared to a conical thread, as well as in the presence of loads on the connection that arise during the thermal expansion of the riser; it is for this reason that surges usually flow sooner or later.

As for the type of welding, the most the best option is gas welding, because with the help of a torch you can always correct inaccuracies in pipe laying from builders. And also using gas welding it is always possible to make a connection in hard to reach places without compromising aesthetics.

An example in which the riser came out of the floor while being partially in the wall. The riser was bent with the help gas burner, the covering of the walls and floor was not damaged at all.

Now we will analyze in detail the radiators themselves that are present on the market. Bimetallic, steel tubular and cast iron radiators are suitable for installation in apartment buildings. As for cast iron radiators, they are used only in low-rise buildings where the heating system operates under relatively low pressure, so you will never see cast iron radiators in houses higher than 9 floors. This is due to the fragility of cast iron. Also, cast iron radiators are distinguished by too rough surface treatment compared to bimetallic ones, this also applies to modern models. Therefore, the most suitable types of radiators for MKD central heating can be called bimetallic and tubular steel. The latter are relatively rare in 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.

Let's take a closer look at bimetallic ones, as they are the most common. As my experience of studying the radiator market shows, and I have a lot of it, it is not always the case that if the manufacturer indicates that the radiator is bimetallic, it is suitable for central heating systems. Manufacturers often save on technological process and perform the so-called pseudobimetal. That is, only the vertical collectors are bimetallic (steel inside, aluminum outside), and the horizontal collector is made entirely of aluminum, which is subject to corrosion upon contact with the coolant (confirmed by repeated requests from customers to my store after 2-3 years). This applies to models such as Rifar Base, Rifar Forza and Sira Gladiator. I would divide all the remaining bimetallic radiators into 4 groups: low-quality, high-quality but not suitable for Russian conditions, high-quality and Rifar Monolit. Poor quality - these are radiators produced under unknown trademarks as a rule in China, the cost is usually in the range of 300-500 rubles per section, the disadvantage is low quality coloring. In the second group I would include all well-known Italian manufacturers, such as Global and Sira, whose only drawback is too narrow vertical collectors, which in a system with a heat exchanger will work perfectly, but in a house where the main coolant is supplied to the radiator, they may not work very well. long and become clogged with scale. I would classify Royal Thermo and Bram as quality ones. The only one that stands apart is the Rifar Monolit, the only radiator on the Russian market that I personally would recommend for installation in a central heating system. And the reason here is in the original design. The quality of the radiator itself does not cause any complaints, but let’s talk about the design in more detail. From the very name of the radiator it is clear that it is not sectional, which eliminates the possibility of leakage between sections. But I think it’s more important, because out of several thousand installed sectional radiators I don’t know of any cases of leakage between sections, the inlet hole into the collector of the Monolith has a diameter of 3/4″, hence there is no need to install adapter liners, which are mounted on a rubber gasket. At that time, when installing the Monolith, the mating part of the faucet with the American one is packed on linen with paste directly into the radiator, bypassing unnecessary connections with a rubber gasket, which over time loses its elasticity and can develop a slight leak. There is also one more plus: the back of the radiator is designed in such a way that it slides smoothly along the brackets, which greatly simplifies the fitting of parts during installation, and the plus for the customer is the absence of extraneous cracking sounds that occur during thermal expansion on the riser and transfer voltage to the radiator. It remains to deal with the most difficult topic for the installers of your heating devices to understand, namely the connection diagram. But a separate topic is devoted to this issue - How to properly install a bimetallic radiator.

Installing new components into a heating system always presents a number of difficulties. This especially applies to replacing batteries, radiators and heating pipes in the apartment. Beyond choice optimal models It is necessary to properly obtain permission to carry out this work.

Obtaining permission to replace radiators and pipes

For a centralized system, replacing heating batteries in an apartment on your own is not allowed. This is explained by the fact that all elements of central heating supply are in common property (RF Government Decree No. 491, clause 6). Installation or upgrading of the system can only be carried out with the permission of the Management Company.

The exception is replacing heating batteries in an apartment in winter. autonomous systems, which are not related to common house ones. To complete all documentation, you must complete the following steps:

1. Application to the Criminal Code about the intention to install new radiators.
2. Obtaining Technical Conditions. It describes the requirements for batteries - heat dissipation, coolant capacity.
3. Selection of batteries according to the obtained parameters. Do-it-yourself replacement of a heating radiator is carried out only in strict compliance with the conditions from the Criminal Code.
4. Choosing a contractor to install radiators or installing them yourself.

Is it possible to replace heating batteries during the heating season? Required condition is to maintain the desired temperature level in other apartments of the house. At a pre-agreed time, representatives of the housing office or management company will turn off the heating riser to which the radiator will be connected. After installation, they will also inspect the equipment and turn on the heating in this circuit again.

Replacing heating batteries using gas welding or another method can be done only after obtaining the consent of the residents of the building whose apartments are connected to this riser.

Choosing heating radiators to replace

After a detailed review of the Technical Conditions (TS), you can begin to select models of radiators and batteries. Currently, there are many types of components for heat supply on the market, and it is difficult to immediately navigate this variety.

Can heating pipes in an apartment be replaced with new ones made of a different material? Yes, if its technical operational parameters comply with the specifications. There is a list of main characteristics that you need to pay attention to first:

• Heat dissipation or power rating. They may be larger or smaller than older batteries. It is important that the capacity is approximately the same. This will affect the cooling of the coolant and, as a result, the temperature distribution throughout the house;
• Maximum temperature and pressure. The first parameter is not particularly important. However, replacing heating radiators in an apartment with gas welding should only be done for those models for which the maximum permissible pressure is equal to the same indicator for central system. Usually it does not exceed 6 bar. But you need to take into account the possibility of water hammer;
• Connection method.

An important point is the battery material and design. They will largely determine the characteristics described above and will affect the difficulty of replacing heating batteries in the apartment.

Traditionally, cast iron radiators were installed in apartment buildings. They are characterized by durability and reliability. However, high heating inertia and mass are their disadvantages. Therefore, to replace heating batteries in an apartment in winter, other types of heating devices are chosen:

1. Bimetallic radiators. They differ from aluminum ones in the presence of steel or copper pipelines through which the coolant flows. Manufacturers increased the maximum possible pressure in this way. The vast majority of bimetallic radiators are sectional, which allows you to choose the rated power.
2. Panel metal. Refer to budget option. They are non-separable. They are characterized by the ease of replacing heating batteries during the heating season, since the radiator has a relatively small mass.

Aluminum batteries do not have the proper technical qualities for installation in a centralized heating system. Therefore, their installation is not recommended. In addition, replacing heating radiators with gas welding will be difficult due to different materials production of pipes and batteries.

You can assemble a bimetallic radiator yourself, but only if you have a special key. It can be rented.

Technology for replacing radiators and batteries

Timely replacement of heating pipes in apartment building will help avoid emergency situations. The same applies to radiators. If you have no experience in performing this work, it is recommended to turn to professionals. But in any case, it is necessary, at least in theory, to know the technology of replacing heating batteries with gas welding. You cannot change the location of radiators or increase their number without agreement with the management company. This can lead to an imbalance in the home's heating system. The day and time of disconnecting the riser to replace the heating radiator with your own hands is agreed upon in advance. Then you need to do the following:

• By using shut-off valves(tap) disconnect the radiator from the system;
• Cut off the radiator inlet pipe or dismantle the unit if it is threaded. In this case, hot or warm coolant will definitely flow - you need to be prepared for this;
• If necessary, new taps are installed;
• When replacing heating radiators in an apartment with gas welding, an influx of fresh air into the room. To do this, you can open the windows;
• After dismantling the old battery, fasteners are installed on the wall for the new one. Their location is checked by the building level;
• Installation of a new battery is carried out only after it is finally attached to the wall. The level is checked first - when replacing heating radiators with gas welding, tilting the radiator is not allowed. This may cause air locks.

For single pipe system A bypass is required to connect the inlet and outlet pipes of the radiators. The package should include shut-off valves, a thermostat and a Mayevsky tap.

After the final replacement of the heating battery, pressure testing is done in the apartment. To do this, you will need a special pump that will pump up the pressure to exceed the maximum by 1.25 times. This is necessary to identify possible defects.

When replacing heat supply batteries in an apartment in winter, it is recommended to close the door to the room and install a temporary insulating layer to preserve heat in other rooms.

Installation of new pipes and heating radiators using gas welding

To replace steel pipes, it is best to use welding machines. Threaded connections are less reliable and may not withstand pressure surges typical of central heating.

Replacing heat supply batteries during the heating season is characterized by a high quality connection. The technology consists of heating the workpieces to the melting temperature and diffusion joining the metal in the weld.

To self-replace heat supply batteries using gas welding, you will need to perform the following steps:

1. Preparatory stage. The site of the future weld is protected, the oxide layer, paint and fat layer are removed.
2. The parts are connected and, with the help of burner gases, melting occurs in a certain area.
3. A special wire is used as solder. Without it, replacing heat supply batteries with gas welding is impossible. When melted, it fills the joints and forms a high-quality weld. The type of wire depends on the material used to make the pipes.
4. After forming a seam when replacing heating pipes in an apartment, scale is removed and the tightness is checked.

If necessary, an additional layer of welding seam is applied. But experts do not recommend doing this. Excessive temperature exposure to pipes when replacing a heating battery with your own hands can affect the characteristics of the metal - it will become more fragile.

Replacing heat supply radiators with gas welding and forming a seam can be done in different positions - horizontal or vertical. It all depends on the brand of wire.

Installation of polypropylene heating lines

Is it possible to replace heating pipes in an apartment building with plastic ones? To do this, you need to select the correct model of highways based on temperature parameters hot water and pressure.

The technology for replacing heating pipes in an apartment with polymer ones is simpler than installing radiators using gas welding. To perform this work you will need metal-to-plastic adapters. welding machine for polypropylene pipes and special scissors for cutting them.

An adapter is mounted on a section of pipe, then the main line is installed. Since deformation of the plastic is possible under the influence of hot water, fastenings are made every 10-15 cm.

As you can see, to self-replace central heating pipes and radiators, you will need special tools and skills to work with them. This will directly affect the quality of the connection and further maintenance-free operation of the heating. Therefore, if desired self-installation It is recommended to make several test connections using gas welding.

Step-by-step installation of radiators using gas welding is presented in the video.

Connection diagrams for heating radiators in apartments of multi-storey buildings.

We work officially under a contract.We provide all the necessary documents for approval of shutdown of heating risers.

Today, increasingly, in old Soviet multi-storey buildings, residents are faced with a situation where they need to replace the heating batteries (radiators) in the apartment.

This is due to the fact that the shelf life of cast iron radiators (there were no others in Soviet times) reaches 50 years, while most houses are much older.

Therefore, it is not strange that they are either forced to do this, since they are out of order, or they want to give their home a presentable and modern look.

FAQ

Whatever the reason, any action can be taken only after answers to the questions have been received:

1. How much does it cost to replace heating batteries in an apartment?
2. What permits are needed for this?
3. Who has the right to carry out such work?
4. What should I replace old cast iron batteries with?
5. Is it possible to replace the heating battery in an apartment for free?
6. When is it better to change heating batteries in an apartment?
7. How to change the heating battery in an apartment yourself and is it possible?

The heating system of a multi-storey building is quite complex design, in which many elements must be taken into account. If during the repair or replacement of radiators in one apartment malfunctions occur, the entire riser may suffer.

Replacing heating batteries in an apartment: when is it necessary?

As often happens, a person is not always ready for change, even when it rings at his door. According to apartment owners, most often heating batteries are replaced in winter in an apartment building, which entails a change in the entire heating system. This is not surprising, since during the non-heating season the pipes do not show their shortcomings.

When do you need to replace the heating in your apartment?

Most often, replacement of the heating system in an apartment building is required if:

1. Depressurization has occurred in pipes or radiators.
2. Heat transfer has become worse.
3. The system is clogged.
4. Changes are required in the interior of the apartment.

The heating system with all its elements and devices belongs to the public utility, therefore, without permission from the law, altering the heating in the apartment and any other actions are illegal.

As a rule, a representative of the housing office gives an assessment of the condition of the old heating and permission to install a new one. Only after the go-ahead for dismantling has been received and a work plan has been drawn up, can you think about how to change the heating battery in the apartment.

Battery selection

When choosing any type of radiator, you need to focus not on its aesthetic appearance, but on its quality. So, for a system that will be equipped with a pump, batteries made of any material are suitable, even cast iron, but of a new type, the main thing is that they are compatible with the pipes and the boiler.

If the circulation in the system is natural, then you should pay attention to the fact that they have low hydraulic resistance.

Also, in a situation where it is necessary to replace the heating system in an apartment, it is necessary to take into account a number of important factors:

The average indicator for determining power is 100 W/m2. If you compare it with the area of ​​the room, you can find out how much power one radiator section should have. At the same time, we must not forget that it must occupy at least 70% of the wall under the window sill, so focusing on systems with high performance, but shorter ones, does not make sense, since cold air from the window, without receiving obstacles in the form of heat from the battery, will be freely reach the floor.

Only after all parameters have been taken into account can you obtain permission from utility companies to alter the system and begin purchasing radiators.

Dismantling the old system

To remove old pipes and radiators, you should agree with the neighbors above and below to replace them. If this was not possible, then the question of how to change a heating radiator in an apartment becomes exclusively personal.

How to replace a heating radiator in an apartment? Dismantling the old system begins with draining it. Housing office workers must do this, since a pump will be required to completely pump out the coolant, after which they shut off the water at the level of the radiators that need to be replaced.

How to change heating batteries in an apartment? It will be necessary to cut off the old pipes at the floor and ceiling level and weld new ones, it is better if they are aluminum-propylene.

If you are replacing heating radiators (batteries) in an apartment with your own hands, then you will need to prepare in advance additional elements that are not included with them:

The tools you need to have are:

• grinder;
• drill;
• adjustable wrench;
• level;
• gas soldering iron.

After that. Once the level marks the place where the old batteries are cut, you can begin to dismantle them, leaving at least 1 cm of thread for connecting the new system.

Only after identifying the places (taking into account all the parameters) where the new radiators will be located can you begin to install them.

Radiator installation

Replacing cast iron heating radiators in an apartment begins with removing all old fasteners, since they may not fit modern models heating systems. Having previously made marks on the wall, new mounts are installed on which the radiators are hung, with the obligatory check of them horizontally using a level.

After this, you can use special metal-plastic connections to connect the battery to the new riser. If the system uses single-pipe wiring, then a bypass is installed between the connections.

If there were no jumpers in the old system, this does not mean that they do not need to be installed on the new one. Convectors of modern radiators differ from Soviet ones and have higher resistance, so a bypass is required.

How to replace a heating battery in an apartment?

If you are replacing heating batteries (radiators) in an apartment in winter, you need to consider:

1. Firstly, disconnecting the riser must be agreed upon with representatives of the housing office(ideally, so that they carry out all the work) about turning off the water.
2. Secondly, only After pumping out all the coolant, you can begin dismantling and installing new radiators.
3. Thirdly, it should be taken into account that All work is given only 3-4 hours, since the entire riser remains without heat.

Work during the heating season to change the riser or batteries is carried out only when the air temperature outside the window is not lower than -10 degrees. Otherwise, you will have to sit without heat, waiting for more favorable conditions.

Activities of the housing office when changing radiators

When residents decide that their heating system is outdated, they ask a fair question: who should change the heating radiators in the apartment.

In this matter, you need to rely on the following facts:

1. The change was caused by a failure (depressurization or other reason) of the system, which means all work must be carried out by utility workers.
2. Old radiators heat, albeit poorly, but if there is a desire to decorate the apartment with more modern analogues, then this “whim” will fall on the shoulders of the user himself.

In any case, the heating batteries in the apartment are replaced through the housing office, even if all expenses are borne by the residents. Without permits, any work is considered illegal. Sometimes consumers ignore such a requirement, wanting to draw up documentation after the fact of the work performed. This can only happen if housing office workers consider new system heating is safe for the entire structure.

If residents have a question about whether it is worth changing the heating batteries in the apartment, then the answer is a definite “yes” if they have become unusable or are simply old. The replacement procedure is not that complicated, even taking into account the paperwork. Choosing a team suitable for this work will also not be difficult, but knowing that for the next 25-30 years the apartment will be heated by beautiful and modern radiators is worth it.
