Heating registers from smooth pipes. Calculators for calculating the parameters of the heating register Gs 2 40 heating register

Heating registers are heat exchange pipes that are installed in houses and serve to heat the indoor air. They are made of materials such as steel, cast iron, copper, aluminum and have a variety of configurations.

You need to select the heating register in accordance with the size of the room, you can enter either one or several sections.

Speaking about the materials for the manufacture of registers, one cannot but say about electric-welded steel pipes, which are common due to their availability, low cost, ease of rolling and great choice types and sizes, although they do not have the best heat transfer.

Steel registers are made from a profile or with a round section of the pipe. prone to rust, so Special attention should be given to welds.

Cast iron registers are reliable and easy to install, but installation can take a lot of effort. They have strong enough connections due to welded flanges and bolts, but there is no resistance to impacts, they can break. Have extremely big weight and look bulky. Most are found from finned tubes.

Copper registers are mainly installed where the entire gasket is already made of copper pipes. Copper has excellent thermal performance, so copper pipes have a small length and diameter, which cannot be said about the cost.

The softness of the metal makes it easy to bend pipes, so welding is only needed to connect individual parts, but additional protection (screen, casing) is required.

The use of copper registers requires compliance with the following conditions:

there should be no solid particles in the coolant;
fittings and other parts in contact with copper can only be made of bronze, brass, nickel or chrome;
grounding is a prerequisite for the process electrochemical corrosion did not go.

Aluminum registers are in demand because their thermal conductivity is considered the best, they are resistant to corrosion and have a long service life, which is probably why they have such a high cost.

Aluminum pipes are made by the method of monolithic casting, so they do not have welds and joints, but the installation requires special welding equipment.

Bimetal registers are made from special type heating pipes with a steel core. The copper or aluminum plate heat exchangers used in such registers can significantly increase the square meters of heating. All heating registers of this type are characterized by a diameter of up to 2 inches. Due to this, the main place of their installation is residential buildings.

Heating registers from stainless pipe You can meet extremely rarely because of the exorbitant cost. Now they are almost never installed.

Types of registers for installation (electric-welded, from smooth pipes)

Electric welding steel registers made of smooth pipes, probably rightfully considered the most popular. The diameters of such pipes are found from 32 to 150 mm.

There are 2 types: serpentine and sectional (register).

Serpentine (serpentine) registers have the shape of the letter S and arc connection. This configuration significantly increases heat transfer, and smooth pipes allow a large volume of coolant to pass through.
Sectional (register) registers are distinguished by the type of connection:
a thread is a design with a serial connection, where the closing pipe, through which the coolant flows from one pipe to another, is located either on the right or on the left;
a column is a design with a parallel flow of the coolant, where all pipes parallel to each other are connected by closing pipes at both ends. This type of connection allows you to create the required length in accordance with the size of the room.

Calculation of registers for a room

When choosing a heating register model, attention should be paid to pipe diameter. Diameters, as mentioned above, are from 32 to 150mm.

The large diameter of the pipes is, as a result, a large volume of the entire heating system. It takes a very long time to heat up such a system and it is more difficult to regulate the temperature, but they are preferable for the operation of the boiler.

It is better to stop the choice on pipes with a diameter of 32 mm, and if the personal production of the register is expected, experts recommend choosing a pipe diameter of no more than 80 mm.

To create heat supply from steel heating registers, the best solution would be to resort to the services of craftsmen. Another option is special programs for calculating.

But for self-calculation, you can use the following method.

Initially, you need to know the following parameters:

total area of the room;
heat transfer coefficient of the register material;
the diameter of the pipes used.

Table. Heat dissipation of one running meter of steel pipe different diameter- to calculate the heating register at a height of 2 meters.

You can use the formula for calculating registers from smooth steel pipes.

Q = 3.14 x D x L x K (Tr – To), where

Q is the amount of heat that the pipe emits, W;

D is the pipe diameter, m;

L is the pipe length, m;

K - heat transfer coefficient (11.63 W / m 2 xC);

Tr is the temperature inside the room;

To is the temperature of the coolant in the system;

t is the temperature difference.
With these values, you can calculate the amount of heat of the heating register yourself.

Example: the length of the 1st section is 2 m, and the diameter of the pipe is 76 mm.

t will be even 60C (80-20).

Thus, the power of one section of the heating register from a steel smooth pipe will be equal to:

Q \u003d 3.14x0.076x2x11.63x60 \u003d 333 W.

To calculate the required footage and diameter of the pipe, only the heat transfer indicators of a linear meter of the pipe should be taken into account.

For example. A room with an area of 20m 2 and a ceiling height of not more than 3m will require 20m of steel pipe, the diameter of which will be 60mm.

When preparing for the installation of heating devices, it is necessary to take into account such parameters as:

wall depth;
location of windows and doors;
the composition of the walls and ceilings of the building, etc.

Structural features

I influence the power of the heating register design features. They are made mainly from pipes with smooth walls, less often from profiled metal.

Important. The parts of the heating register must be located at a distance from each other on the basis of: pipe diameter plus 5cm. Too close location will negatively affect heat transfer.

All models of heating registers have nozzles at the inlet and outlet to connect the pipelines for supplying and discharging the coolant.

Heating registers are installed in 1-pipe and 2-pipe systems. Their connection to the heat supply system provides for the following options:

diagonal;
lateral;
lower (only with small dimensions of the structure or a small number of horizontal elements).

Self installation

Two mounting methods:

detachable bolted connection;
non-detachable welding connection.

The choice should be based on the weight and size of the device, and also take into account the characteristics of the heating system.

As a basis, you can take the rules for installing heating radiators, there is no fundamental difference.

Slope indicator - it is important to take into account, when connecting to the gravity system, the slope along the coolant.

On systems that do not use pump equipment and where driving force is the difference of its partial pressure no such problems.

Installation rules:

Recommended distance, according to technological process, from the wall and windows not less than 20cm.
Detachable installation requires the use of only paranitic linings or linen used in sanitary technical work Oh;
All steel heating registers must be painted to avoid rusting.
Installation is best not carried out during the heating season.

A comparative analysis of the calculated and actual power of the register can be made at the end of the test run of the system, and, if necessary, make structural changes.

For the organization of heat supply large rooms it is impractical to use standard factory batteries and radiators. They have too little heat output and rated power. As an alternative, we can consider heating registers: manufacturing from pipes, calculation rules and installation features.

Advantages and disadvantages of heating registers

Homemade steel or aluminum heating registers differ from standard radiators in their size. They consist of several pipes whose diameter exceeds 32 mm. To organize the circulation of the coolant, the pipes are interconnected by branch pipes.

What is the reason for the popularity of these heat supply devices? First, the possibility self-manufacturing. You can make bimetallic heating registers, steel or aluminum pipes. Much less common plastic models because they don't perform well.

Before you connect the heating registers, you should carefully study their "weak" and "strong" sides.

Benefits of using:

Long service life. For steel and aluminum models, it can be up to 25 years. In this case, the probability of breakage will be minimal;
Great heat dissipation. This is due to the fact that the power of the heating register exceeds this parameter for classic radiators and batteries. Associated with a large volume of coolant;
Easy installation and operation. Since anyone who is at least a little familiar with the rules for organizing heat supply can correctly install heating registers, they can be used in buildings of all types. But most often they can be found in the heating system of large industrial, administrative and commercial premises.

But besides this, it is necessary to take into account the possible disadvantages that a heating register made of a smooth steel pipe may have:

Large volume of coolant. This leads to its rapid cooling;
Minimum air convection. Reduces the efficiency of heat supply;
Unattractive appearance . Most often this applies to homemade designs.

Correctly calculated heat transfer of the heating register directly depends on its design. Currently, several types of these heat supply devices are used, differing not only in the material used, but also in appearance.

The mass of the register filled with water can be very high. Therefore, you need to think ahead reliable system its attachment to the wall.

Initially, you should decide on the type of structure. After all, how to calculate the heating register if it is not known geometric parameters and the principle of coolant circulation? For the manufacture of heating devices, it is recommended to use standard proven schemes.

The determining parameter of choice is the required circulation rate of the coolant in the system and the degree of heat transfer of the register. Based on these requirements, two types of heating devices can be selected:

Sectional. It consists of two or more large-diameter pipes connected by branch pipes. The cross section of the latter should be equal to the same parameter of the supply line. The selection of a heating register of this type is relevant for systems with forced circulation, since excessive hydraulic resistance is created in the structure during the passage of the coolant;
Serpentine. Consist of one pipe, which has bends. It is problematic to make such home-made heating registers. To increase the circulation rate, pipes can be connected with nozzles. But this is not mandatory, as in the models described above.

Since you can make a heating register with your own hands even at home, they are often made, and not purchased ready-made models. But before that, you should perform the correct calculation of the power of the heating register.

For the manufacture of registers, pipes of various sections can be used - round, rectangular or square. Preference is given to the first, since for them the friction of water during movement will be minimal.

Calculation of heating registers

There are several methods for calculating the parameters of heating registers. They differ in computational accuracy and complexity. But for the organization of heat supply using steel or aluminum heating registers, it is recommended to resort to the services of professionals. Alternative option- use special software.

However, in some cases it is necessary to correctly calculate the heating register yourself. To do this, you can use a simplified scheme. You must first know the following parameters:

The total area of the heated room;
Heat transfer coefficient of the register material;
The diameter of the pipes used for manufacturing.

For pipes of circular cross section, the calculation of the specific power of the heating register can be done according to the table. These values are given for 1 m.p. register pipes.

However, this method of selecting a heating register has a number of significant shortcomings. The data are given for rooms where the ceiling height does not exceed 3 m.p., the thermal regime of the system and the air temperature in the room are not taken into account.

Q=P*D*L*K*Δt

Where Q– specific thermal power, W, P- number π - 3.14, D - pipe diameter, m., L– length of one section, m, To- coefficient of thermal conductivity. For metal, this figure is 11.63 W / m² * C, Δt- the temperature difference between the coolant and the air in the room.

Knowing these parameters, you can independently calculate the power of the heating register. Let's assume that the length of one section is 2 m, and the diameter of the pipe is 76 mm. Δt is 60°C (80-20). In this case, the power of one section of the heating register from a steel smooth pipe will be equal to:

Q=3.14*0.076*2*11.63*60=333W

To calculate each subsequent section of the device, the result obtained must be multiplied by a reduction factor of 0.9.

Ribbed heating registers cannot be calculated using this method. Their heat transfer will be higher due to the increased area of \u200b\u200bthe device.

Choosing the material of manufacture for the registers

The next parameter that must be taken into account when choosing a register is the material of its manufacture.

It is rare to find heating registers from a profile pipe - most often steel products of round section are used for this.

Currently, several materials are used for the production of registers - metal, aluminum or bimetallic pipes.

The difference between them lies in the estimated heat transfer and service life:

Steel heating registers from a profile pipe or round section. They are characterized by ease of manufacture and low cost. The disadvantage is the rusting of the surface. When choosing, special attention should be paid to the quality of welds;
Aluminum. They are extremely rare, since special equipment is required for welding aluminum heating registers. But they do have best performance thermal conductivity. Virtually no heat loss;
Bimetallic. They are made from a special type of heating pipes. They have a core made of steel. To increase the heating area, the design has copper or aluminum plate heat exchangers. All bimetallic heating registers are characterized by a small pipe diameter - up to 50 mm. Therefore, they are more often used for organizing heat supply in residential buildings and small industrial and commercial premises.

The material of manufacture directly affects the calculation of the heating register. The main indicator in this case is the coefficient of thermal conductivity. Although aluminum models have an optimal value - their high cost and laboriousness of manufacturing do not allow the use of registers of this type in heating systems everywhere.

For the manufacture of ribbed heating registers, components from steel radiators can be used.

Making registers for heating with your own hands

One of the advantages of using registers in heating systems is the possibility of their self-manufacturing. For this, it is most often used steel pipes round section. Despite the fact that the heat transfer rate of the heating register in this case will not be ideal - the manufacturing process does not require special skills.

For self-produced this heating element will require a pipe with a diameter of 40 to 70 mm. A larger value of the cross section will lead to significant heat losses during the circulation of the coolant. You can make a heating register with your own hands according to the following scheme of work:

Calculation optimal parameters heater - pipe diameter, total length of the section.
Drawing up a drawing to calculate the optimal amount of material.
Do-it-yourself work on the manufacture of a heating register.
Checking the design for tightness.

To accomplish this task, you will need a steel pipe designed to form the main registers and a smaller diameter line. With its help, the registers will be connected to each other and the heating system. You will also need special end caps for pipes.

At the first stage, it is necessary to cut the pipes to the desired length with the help of a grinder. It is not recommended to use a welding machine for this, since at the ends of the heating register from round pipe a flood will form. Then holes are made for connecting pipes. Branch pipes are welded with a welding machine and end caps are mounted. To ensure the safety of the home-made heating register, it is necessary to install an air vent and a drain valve. They are mounted at the top of the structure, but on opposite side regarding the connection point to the heating.

In some cases, upgrading traditional scheme steel or bimetallic heating register. It consists in installing an electric heating element.

So you can make an autonomous source of heat, which will not depend on the operation of water heating. In the event of an accident or technical work, a self-made heating register will generate heat using a heating element. But for this, during installation, install stop valves so that the coolant circulates only inside the heater.

During the selection of the scheme and the manufacture of the heating register, the thickness of the pipe does not matter. The difference in diameters between it and the supply line causes the complete absence of water hammer in the structure.

Installation of registers in the heating system

The correct installation of heating registers can be carried out in two ways - on threaded connections or using welding machine. It all depends on the total mass of the structure, its dimensions and the parameters of the heat supply system.

In general, experts recommend following the same rules as when installing radiators. The difference is only in the size of the structure. If it is necessary to connect the heating register to the gravity system, the required slope indicator must be observed. The heat supply device must be tilted in the direction of movement of the coolant. There are no such requirements for systems with natural circulation.

For correct installation heating registers must be guided by the following rules:

Compliance minimum distances from the wall and window structures. It must be at least 20 cm. This is necessary for technical or repair measures;
For threaded connection of the heating register, only paranitic linings or sanitary linen are used;
All heating registers made of profiled or steel pipes must be painted. This is necessary to prevent the appearance of rust on their surface.

Despite the fact that the heat transfer rate of the heating register will decrease in this case, the life of the structure without repairs will increase significantly.

Installation is recommended not during the heating season. After a test run of the heating system, you can compare the calculated power of the register with the actual one and, if necessary, make prompt changes to the design.

Rules for the operation of heating registers

To increase the service life, it is necessary to carry out a number of measures to maintain the heating registers in working order. It is recommended that a control check schedule be drawn up that includes visual inspection and analysis temperature regime register operation.

In addition, you should periodically clean the internal surface of the structure from scale and rust. For this, it is best to use the hydrodynamic method, since for chemical cleaning a large amount of special liquid is required. This can be done without dismantling the structure - it is enough to install branch pipes during manufacture to provide access to the internal cavity of the register.

Each time before a new heating season, the integrity of the structure, the reliability of welded and threaded joints are checked. If necessary, gaskets are replaced and repair seams are welded.

Is it possible to use heating registers for heat supply of a private house? This practice exists, but for this they order products made of copper pipes. They are characterized by high cost, but at the same time they have a number of distinctive qualities. Their attractive appearance, which differs significantly from steel structures, is also taken into account.

The video shows an example of the manufacture of a register from a steel profile pipe:

Heating radiators are traditional heat exchange devices installed in residential premises. However, one can often come across a picture when the owners, apparently for reasons of economy, prefer to get by with home-made registers, that is, cascaded welded sections of large diameter pipes. This approach is usually widely used in utility or utility buildings and premises, but with careful assembly and painting, registers may well fit into the interior of a living room.

However, the savings with this approach are far from obvious: in fact, any register, in terms of its heat transfer capabilities, usually loses to much more compact and neat externally radiators. In any case, it is not necessary to expect any miracles from its installation. And if so, then the installation of such heating devices should be planned only after the calculations and comparative analysis cost and efficiency. And calculators for calculating the parameters of the heating register will help us in this matter.

The following calculation algorithm is proposed:

First, the first calculator determines the amount of heat loss that needs to be compensated by the heating system. In a word, the required thermal power for a particular room is calculated.
Having the value of the required power, on the second calculator, you can quickly and accurately “design” the heating register with the desired heat transfer - that is, determine its length, number of sections and diameter (section) used for the manufacture of pipes.

Prices for copper pipes

copper pipes

A little lower, under the calculators themselves, the necessary explanations for the calculations will be given.

Heating registers are special devices that are used to increase the efficiency of heat exchange between the environment in the room and the coolant. They are installed in heating systems of industrial, production and storage facilities, as well as residential and office buildings. What are these devices, and what are their advantages, we will tell in the material below.

Varieties of heating registers

According to the structure, the heating registers are steel pipes, combined with the heating system with pipes of a smaller diameter. There are 2 main types of heating registers.

Sectional

Sectional steel heating registers made of smooth pipes can consist of one or several segments, the ends of which are closed with plugs. The incoming pipe with the coolant crashes into upper part sections. Moving from side to side, the water gradually fills the entire section.

For the manufacture of this type of heat exchanger, smooth steel pipes with a cross section of 25-400 mm are used. The most commonly used pipes are 76, 89, 108 and 159 mm in diameter. Insertion of inlet and outlet pipes can be performed on a thread, flange connection or welding.

Additionally, the equipment is equipped with a threaded fitting, into which an air vent is connected. Such steel registers are designed for a maximum coolant pressure within 10 kgf / cm 2 or 1 MPa.

The plugs installed on the sides of the pipe are flat or in the shape of an ellipse. They try to make transitions between pipes as close to the edges as possible in order to increase the heat transfer of the equipment.

Serpentine

In contrast to the sectional, the coil heat exchanger is one long pipe, bent in the shape of the letter S. It uses pipes of a similar section, and there are no areas of their narrowing.

Due to the special shape of the design, the heat transfer of heating registers of this type increases and the hydraulic resistance of the coolant decreases.

In most cases, heating registers are made of smooth-walled pipes made of high carbon steel. However, you can also find appliances made of stainless or low alloy steel, as well as cast iron.

Thanks to the use of heating registers, even if they have a compact size, it is possible to achieve high efficiency heating. In this regard, these devices are actively used in industrial and large warehouses.

It should be noted that the use of registers is especially important in rooms that are subject to increased requirements for sanitary and fire safety.

Calculation of heating registers - how to calculate correctly

When deciding to install this type of heat exchangers in your apartment, you should decide how to calculate the heating registers.

For these purposes, use the following formula:

Q \u003d πd n Lk (t g - t o) × (1 - η from), in which:

π = 3.14 is a constant value;

d n - external section of the pipe, m;

L is the length of the segment, m;

t o - air temperature in the building in which the register will be mounted;

t r is the temperature of the water circulating in the pipeline;

k is the heat transfer coefficient, the value of which is 11.63 W / m 2 ℃;

η out is the heat transfer coefficient of the insulation. If the device is isolated, the value of η of = 0.6-0.8. In devices without insulation, this coefficient is zero.

Let's calculate the heating registers for a pipe with a cross section of 159 mm and a length of 5 m. The water temperature in the circuit is 80 ℃, and the air temperature in the room is 23 ℃.

Q=3.14×0.159×5×11.63×(80-23)×(1-0)=1654.8W.

The result of the calculation of registers from smooth pipes for heating showed the capacity of the heat exchanger, in which one horizontal pipe is used. If it consists of several rows, a reduction factor of 0.9 is applied for each subsequent level.

In order not to delve into the details of how to calculate the number of heating registers, you can use online calculators, however, their results quite often remain far from the truth. In this regard, it is advisable to still understand the formula and calculate the heating registers from pipes in order to check how correct the result is given by the calculator.

During the installation of heating registers, the requirements of GOST should be followed. Since the connection must be strong and reliable, in order to withstand the mass of the device inside the coolant, a welding machine is required.

Device Specifications

Heating registers have several qualities that distinguish them from other heating devices:

Thanks to efficient heat exchange with the surrounding space, small-sized devices are able to heat large-sized rooms.
The manufacture of the heat exchanger is quite simple - you only need a welding machine and an angle grinder with a cutting disc.
You can use any available materials- pipes made of cast iron, stainless steel or steel.
The devices are capable of withstanding high pressure(10 kgf / m 2) and can work on any heat carriers - water, oil, other liquids, steam.
You can assemble the device both according to ready-made drawings, and according to your own drawings. Allowed various options configuration, plugs, additional elements and finishing materials.
The final cost of a smooth tube heat exchanger will be lower than that of other devices with a similar level of efficiency.

It should be noted that the greater the total surface area of the device, the higher its heat transfer. In turn, the area depends on the cross section of the pipe and the length of the section.

Please note that the efficiency of the equipment will depend on the number of levels and the distance between them, the configuration of the device (S-shaped or sectional), the type of material used, as well as the presence of insulation and the properties of the coolant.

In most cases, heating registers have the following characteristics:

For the heat exchanger, electric-welded pipes made of carbon steel are used.
The pipe connection is made in one of the ways - flanged, on an external thread, and welded.
Maximum value pressure - 10 kgf / m 2.
The cross section of pipes in sections is 32-219 mm.
The minimum indent between levels is from 50 mm.
The cross section of the connecting jumpers is from 32mm.

Heating registers with heating element

In cases where it is impossible to lay heating pipes in the room, install special kind registers - with a heating element. Its power ranges from 1.6-6 kW, and the required operating voltage 220 V at frequency alternating current 50 Hz.

Sometimes a circulation pump is included with the device, which ensures efficient heat transfer of the heating register due to increased circulation of the coolant.

If the equipment works autonomously, it is filled with antifreeze. In this mode, the heating element is able to maintain the surface temperature within 80 ℃.

In cases where devices are built into a common heating system, the heating element turns on at the moment the coolant temperature drops, or turns off if there is no need for it.

Equipment Advantages

The main advantages of this type of heat exchanger can be considered:

ease of use;
ease of maintenance (cleaning);
the presence of a large heat-releasing area with small dimensions;
high fire safety;
economical consumption electricity in the presence of a heating element;
possibility of use as a heated towel rail;
wide area applications - can be installed in warehouses, in production shops, trade pavilions and office buildings, as well as in hospitals and clinics.

conclusions

If you decide to equip your home with this type of heating appliances, we advise you to carefully understand the features of its operation, as well as study the intricacies of creating and installing registers. Additional reference literature will greatly help you with this.

Not only radiators, but also factory-made and self-manufactured heating registers can be used as heating devices. Previously, such heating devices were installed most often in garages, warehouses, industrial workshops and other commercial facilities. In order to reduce the cost of installing autonomous heating systems, such products began to be used in residential low-rise buildings. It is immediately worth noting that space heating with the help of heating registers is less effective in comparison with batteries. The latter benefit from a larger heat transfer area formed by additional plates that are absent in the registers of the basic design. If desired, the owner of the object can remove this shortcoming by welding vertically oriented metal plates to round pipes. Otherwise, this problem is still solved by increasing the number of welded pipes of smaller diameter. Such a modification of the design of heating registers is resorted to not only in order to increase the heat transfer of the device, but also to implement design ideas.

For the manufacture of heating registers, smooth-walled pipes of the same diameter and the same length are prepared. The diameter can be from 32 to 80 mm. Wider tubular products should not be used, because household boilers will not be able to provide the heater with a sufficient amount of coolant. The registers will not be able to warm up well, which means they will not provide heat to the room in which they are installed.

Using gas welding or electric welding, these workpieces, located parallel to each other, are welded together with nozzles of a smaller diameter. According to the transverse pipes (pipes), the coolant flows, circulating in the heating system of the house.

Classic designs of heating registers

Option #1 - horizontal register

Most often, in the manufacture of a heating register, two or three parallel pipes laid in a horizontal direction are connected. The distance between adjacent sections in the register must necessarily exceed the diameter by 50 mm. Coil designs of registers are also popular, divided into several types depending on the method of connecting devices to the heating system.

Coil-type heating registers: L - length of the heater, D - pipe diameter, h - distance between pipes (more than diameter by 50 mm)

The length of the heaters is selected in accordance with the dimensions of the room or room in which it is planned to install the heating system. In addition to the listed types of designs of heating registers, there are also:

single-pipe products;
four-pipe devices;
five-pipe models, etc.

The number of pipes used in one heating register depends on the area of \u200b\u200bthe heated room, the quality of the thermal insulation of the object, the presence of other heat sources in the room, etc. Going through the possible pipe diameters, calculate optimal dimensions products in which the optimal temperature regime will be maintained in the heated room.

Horizontal heating registers made of smooth pipes are used for bottom wiring pipeline. In this case, the products are carefully placed around the perimeter of the room closer to the floor surface. In a residential building, pipes run under the windows. AT industrial premises the location of heating devices depends on the height of the ceilings, the features of the layout of the facility and the placement of industrial equipment.

Heating registers successfully heat social facilities. Caring for such heaters is much easier than for cast iron batteries.

Option #2 - vertical registers

During the redevelopment of apartments and the expansion of their living space due to balconies and loggias, it is necessary to dismantle the batteries installed by the developer during the commissioning of the object. At the same time, the dismantled radiators are replaced by vertical heating registers welded from a large number round pipes of small diameter. These heaters are placed in a wall located next to the window opening.

If necessary, vertical heating registers are closed with decorative grilles, which turn an indispensable element of the heating system into an interior decor item. You can disguise the location of the "bundle" of parallel pipes using mirrors, colored glass, mosaics, wrought iron lattice, as well as by placing shelves, hangers, cabinets and other useful items of not bulky furniture.

It is possible to ensure the movement of the coolant in a vertical register installed in an autonomous heating system of a private house using circulation pump. Horizontal registers are also used in the natural circulation of the coolant, if they are installed with a slight slope (0.05% is enough).

How many registers will it take to heat a house?

Pipes supplying coolant to heating appliances can also be considered registers to some extent. And the heated towel rail installed in each bathroom is also a kind of heating register. When calculating the exact number of heating registers required for comfortable space heating, a number of factors that affect the amount of heat loss are taken into account:

thickness bearing walls and the material of their manufacture;
glazing area;
Number of doors;
thermal insulation of the floor and ceiling;
orientation of the house to the cardinal points, etc.

In a simplified calculation, the heat transfer of one meter of pipe is taken into account. For example, it has already been calculated that one running meter A 60 mm diameter pipe is heated by one square meter living area of the premises (provided that the height of the ceilings is not more than 3 m).

If you purchase ready-made heating registers instead of radiators, you will not be able to achieve significant cost savings. It is possible to reduce financial costs only in the case of self-manufacturing of register-type heaters from materials purchased in bulk with discounts on the market. Welding work must also be done by hand. Otherwise, the cost of the services of a professional welder will cover all the benefits of buying pipes and fittings in bulk.

Mounting methods: welding or threading?

The biggest problem in conducting installation work assembly and installation of heating registers are welding works. Heating devices are assembled from separate parts outdoors, and then, from prepared blanks, the heating system is installed using gas welding. Welds can be replaced threaded connections, which are inferior to them in strength and durability, but subject to the technology of work and use modern materials can ensure long-term operation of heating equipment.

The heating register in the garage or in the warehouse is an independent device that allows you to heat the room technical purpose with the help of electricity

Homemade registers from round pipes

On the market, you can purchase home-made heating registers sold by professional welders. If a finished goods do not fit you in size, then the welders will make heating appliances according to custom order. Quality homemade products is not questioned, therefore they are built without fear and risk into autonomous systems heating.

Popular with consumers and "samovars" with heating elements. This is the name of the heating registers, which independently heat individual rooms due to electricity. Instead of water, oil, antifreeze or any other non-freezing liquid is poured into the pipes. The coolant is heated by a conventional heating element operating from a network with a voltage of 220 V. "Samovars" in their design resemble oil coolers produced in the factory. "Samovars" are used in outbuildings where it is impossible or impractical to build a water heating system. Heating appliances operate in offline, while their performance depends only on the availability of electricity.

Samovar is one of the types of heating registers that are not connected to the heating system of the house, but heat one of the rooms using electricity

Homemade register from a profile pipe

To make a heating register from a profile pipe, choose a product with your own hands rectangular section(60 by 80 mm), the wall thickness of which is 3 mm. A home-made heating battery (register) is assembled in several stages:

first cut the pipe into several pieces of a certain length;
then, on the blanks, markings are made for the holes into which the jumpers will be welded;
four jumpers are made from an inch round pipe (25 mm);
cut plugs from a 3 mm sheet of metal, the size of which is determined by the rectangular section of the profile;
holes are cut out for jumpers in the places of the marking, while in the upper and lower tubes of the register there should be two holes on one side, and in the middle tube - four holes (two on both sides of the part);
three pipes are laid out on wooden stands (beams), parallel to each other;
jumpers are inserted into the holes in the pipes, the parts are leveled and each jumper pipe is seized by electric welding in three places;
after product with horizontal position flip to a vertical position;
they begin to weld all stuck jumpers in two seams, adjusting the welding current to prevent the formation of places of possible leaks;
after the profile pipes are cleaned of slag and metal debris that got inside the cavity of the product;
previously prepared plugs are applied to the ends of the profile pipes, they are grabbed diagonally, and then they are thoroughly boiled around the entire perimeter of the rectangular section of the profile;
grinder lightly grind the welding seams throughout the heating register;
in the upper pipe of the homemade register, a hole is cut out for the Mayevsky tap;
the connection of the register to the heating system can be made from below, from the side, from above, or by a combination of the above options (from below and above, diagonally, etc.):
the exit hole is closed with a plug, the register is filled with water, after which the master looks through all the welded joints, excluding the possibility of leakage through microcracks;
weld floor supports made of steel angles or brackets that allow you to fix the device on the wall.

Such a register has a high heat transfer due to the large amount of coolant flowing through profile pipes. Jumpers should be placed as close as possible to the end edges of the horizontal parts. The coolant is supplied through the inlet pipe located in the upper pipe. After passing through all the elements of the device, the coolant flows out through the outlet pipe located on the bottom pipe.

The heating register of four parallel pipes connected by side riser pipes heats the living space

As you can see, it’s not difficult to make a heating register with your own hands if you have a welding machine and experience working with it. Home-made heaters can be welded exactly according to the dimensions of the heated room. Three times more funds will have to be prepared for the purchase of a ready-made heating register than for the purchase of all necessary materials for self-welding of the product. To ensure long-term operation of the device, purchase pipes made of carbon steel, low-alloy stainless steel or cast iron.
