What is the connection of heating radiators is better

Especially in the winter, selecting the appropriate heating system for your house is essential to comfort and energy economy. The radiator is one of the most important parts of any heating system. Radiators are essential for distributing heat throughout your house, but choosing the right type can be difficult given the variety of options available.

Efficiency, style, and affordability are some of the considerations that go into choosing the best heating radiator. Every type of radiator has pros and cons of its own, so it’s important to carefully consider your options before choosing one. Knowing the different kinds of radiators and their distinctive qualities will help you choose one that will suit your needs for heating and your budget.

The classic cast iron radiator is among the most popular varieties of radiators. For many years, cast iron radiators have been a mainstay in homes due to their timeless style and exceptional durability. Renowned for their capacity to hold onto heat, these radiators offer a constant and even warmth throughout the space. Cast iron radiators retain heat well, so even though they might take a little longer to heat up than other varieties, many homeowners prefer them.

Conversely, contemporary substitutes like steel and aluminum radiators are becoming more and more well-liked because of their quick heat conduction and lightweight design. Particularly aluminum radiators are renowned for their rapid heating qualities, which makes them perfect for spaces that need to warm up quickly. Furthermore, there are many sleek and modern designs available for both steel and aluminum radiators, giving you more options when it comes to matching the style of your home’s heating system.

The kind of heating system that the radiator will work with is another factor to take into account. It’s critical to choose a radiator that will work well with your chosen setup, regardless of whether you have a conventional boiler system or are thinking about using electric or hydronic systems as alternative heating methods. You can reduce energy waste and maximize the efficiency of your heating system by making sure it is compatible.

Types of heating systems

The type of heating system and the connection type chosen have a significant impact on the amount of heat that the heating radiator will radiate. You must first comprehend the various types of heating systems and how they vary in order to select the optimal choice.

One -pipe

When it comes to costs, the one-pipe heating system is the most affordable choice. Thus, this kind of wiring is preferred in multi-story buildings, even though such a system is not unheard of in private. This plan places the radiators along the highway one after the other, with the coolant entering the first heating parting through the entrance of the second, and so on. In high-rise buildings, the riser or the heating boiler’s input is connected to the final radiator’s output.

One instance of a system with just one pipe

The inability to modify radiator heat transfer is a drawback of this wiring technique. You can control the remainder of the system by installing the regulator on any of the radiators. The coolant temperature variance across radiators is the second major drawback. The people closest to the boiler receive excellent heating, which causes them to get even colder. This is the result of connecting the heating radiators in a sequential manner.

Two -pipe wiring

The supplier and reverse threads on the pipeline are what distinguish the two-pipe heating system. It turns out that all of the radiators are connected to the system in parallel because each radiator is connected to both. This is advantageous since each of them receives coolant at the same temperature at the input. The second benefit is that you can install a thermostat on each radiator and adjust the amount of heat it secretes with its assistance.

One drawback of this kind of system is that it requires nearly twice as many pipes to wire. However, balancing the system is a simple task.

Where to put radiators

It is not by accident that heating radiators are traditionally positioned beneath windows. The cold air coming from the windows is cut off by the warm air rising. Warm air also raises the temperature of the glass, preventing condensation from forming. The radiator must take up at least 70% of the width of the window opening in order for this to work. This is the only way the window won’t fog up. Consequently, choose the radiator power such that the width of the entire heating battery does not fall below a specified value.

How to install a heating element beneath a window

Furthermore, it is imperative to determine the ideal radiator height and location beneath the window. It needs to be positioned with about 8 to 12 cm between it and the floor. Lifting it above will make the legs cold, and lowering it below will make removal difficult. Another regulated distance is that to the window sill, which is 10 to 12 cm. In this instance, warm air will freely curl the windowsill, acting as a barrier, and rise up the window glass.

The distance to the wall is the final measurement that needs to be kept when connecting heating radiators. It ought to be three to five centimeters. In this instance, the room will heat more quickly as rising warm air currents rise along the radiator’s back wall.

Radiator connection schemes

The method used to supply the coolant to the radiators will determine how well they warm. The number of ineffective options is increasing.

Lower connection radiators

There are two types of connections on all heating radiators: lateral and lower. The lower connection cannot have any disparities. The input and output pipes are the only two present. In light of this, the coolant is allocated while also being supplied to the radiator.

Lower radiator connections for single- and two-pipe heating systems

In particular, where the installation instructions—which must be accessible—state where the feeder should be connected and where the opposite is indicated.

Heating batteries with a side connection

Larger options are available when connecting options sideways: in this case, the supply and reverse pipelines can be connected to two and four pipes, respectively.

Option No. 1. Diagonal connection

Manufacturers experience their heating devices and data in the passport for thermal power – for such an eyeliner – in this manner, as it is the most efficient and accepted standard for heating radiator connections. Heat is applied to all other forms of connections less successfully.

Heating radiators’ diagonal connection diagram for a two-pipe and one-pipe system

All of this is possible because hot coolant is supplied to the upper entrance on one side, travels through the radiator, and exits on the lower, opposite side via a diagonal battery connection.

Option No. 2. One -sided

Pipelines are connected on one side, feed on top and return from below, as the name suggests. This type of connection usually prevails, so it’s convenient when the riser passes from the side of the heating device, which is common in apartments. In cases where теплоноситель подводится снизу, такая схема используется незасто — располагать трубы не очень удобно.

Side connection for a system with one pipe and two pipes

The efficiency of heating is only 2% lower with this configuration of radiators. However, this only applies to radiators with a maximum of 10 sections. Longer batteries will cause the farthest point to warm up slowly or possibly become cold. Extensors of the flow—tubes that bring the coolant a little bit farther than the middle—are used in panel radiators to address this issue. Improved heat transfer can be achieved by installing the same devices in bimetallic or aluminum radiators.

Option No. 3. Lower or saddle connection

The saddle connection for heating radiators is the least efficient option available. Losses range from 12 to 14 percent. However, this is the least noticeable option because pipes typically fit under or on the floor and it is the most aesthetically pleasing way to do things. Additionally, you can use a radiator that is a little bit stronger than necessary so that the losses do not alter the room’s temperature.

Sedel heating radiator connections

This kind of connection should not be made in systems with natural circulation, but it functions well in the event that a pump is present. Not worse than a side in some situations. Heat transfer increases, vortex flows occur, and the surface heats up to a certain speed as the coolant moves. The behavior of the coolant cannot yet be predicted because these phenomena have not been thoroughly investigated.

The efficiency of heat transfer – how best to connect heating radiators

Methods for joining heating radiators

Comfort—comfort, comfort, and more comfort. When it comes to residing in the home, we are constantly reminded of this thought. I agree; who wouldn’t want their home to be cozy and comfortable all the time? Such things don’t exist. And now for the second query: what factors influence residence quality? There are numerous factors, but the warmth of the home is the one that interests us the most. It is supplied by a skillfully designed heating system, in which radiator connections are crucial.

We will talk more about this in the future. We will first ascertain the various forms of heating that are currently in use. They are two in number:

How do they vary from one another? the quantity of materials used and the number of contours that result from it.

One -pipe scheme

This is actually a ring of pipes with a heating boiler in the middle. When a system with natural coolant circulation is employed, the simplest wiring scheme works best in one-story buildings. or in structures with forced circulation that are multi-story.

Let’s just say that, despite being extremely economical in the materials used in its construction, this scheme is not the best. However, she has a significant flaw in that she cannot control the amount of heat. It is difficult to install some control partitioning in such a scheme. Consequently, the heat recoil indicator is equal to the designed in homes where the denouement is precisely a single-pipe circuit. It is crucial to compute this indicator accurately for this reason.

Take note! Radiators can only be connected sequentially when using one-pipe heating. That is, heat is produced as the coolant runs through each radiator individually. Additionally, the device receives less heat the farther it is along the chain.

Two -pipe scheme

The feed and return contours are the two shapes in this scheme. The heat carrier enters the first contour and is allocated to the boiler based on whether it is made of steel, aluminum, bimetallic, or cast iron for heating radiators. Unexpectedly, though, the coolant is dispersed equally among all batteries, which is a major benefit of this connection design.

An important point is that each radiator can have its temperature adjusted by opening or closing the passageway that leads into it when there is a two-pipe connection. This is where a standard cutting valve is installed, enabling you to adjust the coolant volume in each battery.

Place of installation

Heating radiator installation

It appears that the location of the heating radiator’s installation has been decided for some time. Its primary purpose is, after all, to produce heat. But let’s examine the task more broadly. Radiator installation is a serious task. It will be necessary to establish some temperature norms with their assistance in order to influence the ideal regime in the apartment. Therefore, the best places for them to be installed are next to the entrance doors, under the windows, or where cold air can enter. In other words, stopping the cold air zone is a different task.

And there’s "but" once more. All you need to do is place a heating radiator beneath the window; that’s half of it. There are some standards that need to be considered. These standards and numerous other factors determine how the heating radiator should be connected correctly.

What are some of them?

  • Firstly, any batteries-aluminum, bimetallic, steel or cast-iron-should be mounted horizontally. A small deviation of 1 degree is permissible, but it is better to set the devices exactly horizontally.
  • Secondly, the distance from the radiator to the windowsill should be within 10-15 cm.
  • Almost the same distance should be from the floor to the battery.
  • From wall to radiator, it should not exceed 5 cm.

The most accurate and effective heat transfer of heating devices is determined by these norms. As such, acknowledge them as a means of direction.

Ways to connect heating radiators

You can now move on to the main subject and examine the connection of heating radiators in detail. Proper connection of heating batteries can be achieved in three ways.

Method No. 1 – lateral connection

Radiator side connections

The most typical kind of connection for a city apartment’s heating system. A pipe denouement is constructed vertically along the floors of apartment buildings, connecting one apartment to the next. As a result, risers refer to the vertical forms of the feed and return.

The name comes from the way the batteries are attached to them from the side. The connection is typically made in accordance with the following scheme:

  1. Putting – to the upper pipe.
  2. Return – in the lower.

Nevertheless, if the question impacts the circuit with forced coolant circulation, this is not so fundamentally true. It’s true, according to experts, that this plan was chosen with purpose. The efficiency and beneficial effect of the heating device are decreased by 7% when the nozzles are changed while the batteries are still in use. Given the importance of this indicator, consideration must be given to the radiators when the house’s heating system is installed. The heating system has no insignificant points or indicators. A small departure from the standard can result in sufficiently significant fuel and heat losses, and consequently, financial losses.

And a single instant. The side connection to the heating system is ideal if there are no more than 12 sections in the battery. A diagonal connection, also known as a cross, is utilized when there are more sections.

Method No. 2 – diagonal connection

According to experts, the diagonal connection is ideal. The heating contours are connected in this way for this purpose:

  • Feed – to the upper battery pipe.
  • Reet – to the lower, but on the opposite side of the device.

In other words, the radiator connects the two contours in accordance with its diagonal. Thus, the moniker. This connection has the benefit of evenly distributing the coolant inside the radiator, which causes heat to be generated throughout the whole surface of the apparatus. This is how substantial fuel savings are attained.

Method No. 3 – Lower connection

It is very uncommon to connect Rifar radiators to the heating system using this method. The lower connection has numerous issues, most notably with the coolant’s even distribution throughout all of the radiators. In a single-pipe connection diagram, this kind is utilized when the radiators are installed one after the other and the coolant flows through the chain between them.

Lower radiator connection

When it comes to heating a one-story home, the Leningradka scheme is among the most popular. In actuality, the radiators are cut into a looped pipe. It’s very easy to connect them; pipes are diverted from the lower pipes that collide with the contour. It transpires that coolant enters each radiator as it moves through the circuit in a closed cycle. However, the heating device receives less heat the further it is from the direction in which the hot water is moving.

How should one proceed? There are two ways to deal with this issue:

  1. Increase the number of sections of radiators located in rooms long from the boiler.
  2. Install a circulation pump that will create a small pressure inside the heating. It is it that will allow to evenly distribute hot water through the rooms.

By the way, the energy-dependent system is instantly created by the circulation pump. There is a drawback to this. The problem is that many suburban villages routinely experience power outages. Thus, the lower connection issue still exists. However, bypas installation must be done in order for the coolant to continue moving even when the pump is off.

Conclusion on the topic

Thus, you were able to confirm that connecting radiators—both rifle and other kinds—is a challenging and crucial task. In city apartments, a lateral connection is thought to be the best option. When it comes to building private homes, the diagonal scheme works best. The lower connection has far too many issues. Furthermore, testing and experience revealed that this option is characterized by excessively high thermal losses—up to 40%—due to improper installation process organization.

Choosing the right heating radiators for your home is crucial for efficient heating and insulation. The connection of heating radiators plays a significant role in determining the effectiveness of your heating system. Whether you opt for a single-pipe or a double-pipe connection, each has its pros and cons. Single-pipe systems are simpler and more cost-effective to install but may lead to uneven heating across the radiators. On the other hand, double-pipe systems offer more uniform heating but are generally more complex and expensive. Additionally, factors like the size of your space, insulation levels, and personal preferences also influence the choice. Ultimately, understanding the connection types and their implications will help you make an informed decision to ensure your home stays warm and comfortable while optimizing energy efficiency.

Heating radiators connection schemes – which is better

Whether it’s a private home, an apartment, or a cottage, we’ll talk about warmth and comfort in the house today.

The ideal heating is cozy, cost-effective, and warm. In practice, there are a good number of different radiator connection schemes:

  • parallel connection (one -sided scheme);
  • diagonal (cross);
  • one -pipe (apartment version);
  • one -pipe with a jumper (apartment version);
  • two -pipe scheme (apartment version);
  • single -pipe lower (autonomous heating);
  • single -pipe lower with a jumper or tap (autonomous heating);
  • two -pipe lower (saddle);
  • two -pipe diagonal (autonomous heating, with and without pump).

The aforementioned circuits for connecting heating radiators are examined in this article.

If the apartment has centralized heating, we have limited options for connecting radiators; if a radiator needs to be replaced, we must simply repeat the current connection scheme. After that, we’ll try to figure out which autonomous heating system is the most efficient and cost-effective for homes, cottages, etc.

Parallel connection of heating radiators (one -sided scheme)

Given that the radiator is not completely heated, this connection is not very effective.

Particularly significant when considering radiator lengths exceeding one meter (panel type) or ten sections (bimetal, aluminum). There is a lot of heat loss. Thus, use a diagonal connection when installing large radiators in your apartment. Details about him are below.

Diagonal connection of radiators (cross)

More efficient than parallel (one-sided) heating because the coolant heats the radiator uniformly throughout.

The room is better heated as a result of the radiator’s increased heat transfer.

One -pipe scheme (apartment option)

In apartment buildings, this connection scheme is very common (from 9 floors and above).

A single pipe (a riser) descends from the technical floor passes, hitting every floor before landing in the basement, which also houses the return pipe. With this kind of connection system, the upper apartments will be warm because the water in the pipe will cool after traveling through all the floors and providing heat to the bottom.

Additionally, such a system would "ring" if there was no technical floor (houses with five stories or less). One pipe (a riser) emerges from the basement, travels through every floor, circles the apartment on the last floor to the subsequent room, and descends into the basement via every floor as well. Who is lucky in this version is unknown. All of the apartments on the ground floor are heated by the same pipe, which may be warm in one room where it rises and cold in the next.

One -pipe diagram with a jumper (apartment option)

This option is marginally superior to the previous one because it aims to achieve uniform heating of all apartment radiators on risers.

By lowering the jumper resistance that leads to the creation of radiators, the coolant circulates through the riser and partially mixes with the radiator to provide uniform heating across all floors.

The most important thing in this situation is that no resident will place the crane (or close it) on the jumper; if they do, a "copper basin" will cover the entire "undertaking" of engineers using a jumper. Some homes just lessen the jumper’s diameter because they are aware of these situations.

In the event of an accident or repair, this tap on a jumper is necessary; if the radiator was "flowing" (broken), it is removed and replaced. The jumper then acts as a "bypass between the apartments, regardless of when the coolant flow stops."

Two -pipe (apartment option)

This choice is practically perfect for residential complexes. Here, there is a "return" pipe and a feed pipe.

There is more heat transfer when employing these circuits. Both the room’s temperature and the radiator’s warming up are improved. In the event of an accident, installing the jumper becomes unnecessary.

When installing long radiators, don’t forget to install the "Maevsky Kran" on them to remove air from the heating system and keep in mind the prior advice regarding the diagonal connection.

We’ll go from multi-story apartment buildings to autonomous heating.

One -pipe diagram with a lower connection (autonomous heating)

This old and inefficient way of connecting radiators is being used.

In practice, how many times did I have to redo this heating? In a system like this, the coolant "flows" where it "easier" (through a pipe with a larger diameter). and exhibits resistance when trying to "go" into a radiator.

Only from below does the radiator warm up poorly, and even then, not everyone or every time. The modification is not negotiable. There is a lot of heat loss—up to 30%.

Lower one -pipe with a jumper or crane (autonomous heating)

Lower radiator connection Crane heating on a sweater.

The same choice, albeit somewhat enhanced (modified). Here, things have already improved (try to regulate).

We "drive" the coolant into the radiator by using a jumper with a smaller diameter on a "sunbed" or shut-off valve. If a diagonal connection is also used, then this option is legitimate. Cranes are used to start regulating such a system from the boiler. Proceed now.

Two -pipe lower (saddle)

Due to its "feed" and "return," this option is superior to the others. It functions and has good regulation. However, there are minor defects and heat loss in this option.

Thus, we got "to the most efficient radiator connection diagram," in my opinion.

Selecting the correct kind of radiators is essential for heating your home. We’ve looked at a variety of options in this post, including cutting-edge underfloor heating systems, contemporary panel radiators, and classic cast iron radiators. Every choice has a unique set of benefits and things to think about.

For many homeowners, cast iron radiators are a timeless option because of their excellent heat retention qualities and classic design. They can improve the aesthetic appeal of older or period-style homes and offer consistent warmth. Nevertheless, compared to more modern options, they might need more upkeep and take longer to heat up.

Panel radiators, on the other hand, provide effective heat distribution and come in a variety of sizes and designs to fit a variety of spaces. With their rapid heating and individual control, you can easily regulate the temperature in every room of your house. In addition, panel radiators are a popular option for contemporary homes due to their ease of installation and maintenance.

Underfloor heating systems are a compelling option for individuals looking for the highest level of comfort and energy efficiency. These systems get rid of cold spots and make the whole space feel comfortable by distributing heat equally over the floor. Underfloor heating offers a luxurious heating solution and can result in long-term energy bill savings, even though installation costs may be higher initially.

In conclusion, a variety of factors, such as your budget, aesthetic preferences, and heating requirements, determine the best choice of heating radiators. Whether you choose the understated elegance of underfloor heating, the adaptability of panel radiators, or the classic charm of cast iron radiators, proper installation and upkeep are crucial to optimizing comfort and efficiency in your house.
