The boiler can be called a heart heating system. However, that the heating system works efficiently, it is not easy enough to successfully choose the boiler and connect it correctly. It will be necessary to choose the correct heating scheme. If at least one device is incorrectly connected, it will greatly affect the entire system. Therefore, it is important to consider what the strapping of the boiler is, and what is the sequence of its installation.
copper pipe strapping 1. Wrinking with natural circulation. This option is the easiest. Here, as can be seen from the name, there is no pump, and the coolant moves through the highway due to physical laws. All settings are manually exhibited, and also need to be observed for the operation of the system. In order for such heating regularly, it is necessary to take into account some tips:
2. Forced circulation. This kind of strapping is the most common. It has many advantages. One of the most important, is the temperature adjustment of each battery. The principle of forced circulation is that the coolant may flow through high speed, thanks to the pump. The only disadvantage of this option is the dependence of the pump from electricity. When it is turned off, the pump ceases to work. However, there are 2 ways to solve such a problem:
3. Collector layout. Although such an option is the most expensive and complex in terms of installation, but it is the most efficient, convenient and energy-saving. Its essence is that all the pipes from the boiler pass through a special device called a collector. In this node there are various valves, cranes, air drains, measuring devices, and so on. From the collector there is a separate layout to other devices. There are a number of advantages that appear thanks to this method:
4. Binding on primary secondary rings. This way is more often used in buildings where many consumers. There is more than one circulation pump here. The essence of this wiring is as follows: to a small contour, where the heated coolant is located, pumps are connected, which by necessity take this water to the consumer. There are 2 types of contours connected to the boiler:
cascade boilersElectric boiler is not installed. Basically, the complexity is associated with the configuration of the automation.
Now about the installation of a boiler operating on liquid fuel. It is better to be done by experts. However, there are basic principles that need to be taken into account for the successful operation of this unit:
Metalplastic consist of 5 layers, which include 2 layers of plastic, 2 glue and 1 aluminum. The diameter of such pipes from 16 to 63 mm. They have such advantages:
the strapping of the boiler room using polypropylene pipesThe tasks and purpose of the boilers are understandable to everyone. This is the literally "heart" of the entire heating system, without which the coolant simplicity will not warm up to the required temperature and provide comfortable accommodation conditions. But in order for all components of the block elements fully functioned, the impunity of the heating boiler by polypropylene, the schemes and photos of which will be presented in this article.
The initial task, with the purpose of which the heat boiler connection schemes were developed - protect all the components of the heating node from overheating and, accordingly, from breakage. This ensures the execution of all key performance characteristics Heating apparatus.
Different examples of schemes
The binding of the boiler, if we say quite simple, it's all that is located between the boiler / oven and radiators. The functionality of the entire system and the rational spending of finance depends on how correctly and in accordance with the technical recommendations. Important! Competently chosen I. implemented scheme Connecting the heating boiler Even a low-power unit makes it more efficiently, moving out its energy resource to the thermal highway.
But even more profitable to carry out the strapping of the heating boiler with their own hands, because there is no need to resort to help specialized firmsproviding similar plan services. Of course, if you do not own certain skills in this area of \u200b\u200bactivity and are afraid that you can not cope with the realization of the task, it is better to trust the connection of the heating boiler. Believe me, sometimes it makes sense in the overpayment, because not everyone can properly assemble such a rather big thermal block, without allowing errors that, subsequently, can lead to a decrease in the quality of the equipment and its breakdown.

Classic pattern of strapping
Properly performed blockage of a gas or solid fuel boiler is a guarantee of the efficient operation of the entire heating unit. In this process, it is necessary to pay special attention to this moment as adjusting the temperature mode at the inlet and at the outlet of the thermal circuit. Due to this, it is possible to reduce the difference of temperatures to a minimum, which, in turn, causes the use of the minimum amount of fuel, and, as a result, reducing financial spending on their purchase.
At first, while water in the system does not reach the required temperature, the movement of the coolant will be carried out according to the auxiliary highway. After the temperature regime of the thermal carrier is to respond to a given thermostat value, it will go to the main pipeline by which the heating of the room will be carried out.

What is included in the package
Virtually any boiler strapping scheme implies the use of such structural components:
In addition, you will need another set of wrenches and a welding machine, which, for the absence of such, you can easily take rent in a construction store.
Accessories that are connected to the wall gas heating boiler are necessarily exposed to the strapping scheme. You can use the connection of the nodes using three ways to:
If you plan to equip your housing with a single-circuit thermal block, then it will be not so difficult to cope with the task.

When performing a strapping of a boiler with their own hands, it is necessary to steadily follow the scheme that is proposed by the manufacturer of this device. Otherwise, even minor flaws allowed when installing a thermal highway can reduce the efficiency of the entire installation in general or, worse, to the malfunction of the heating unit!
Special attention is paid to the design of the dual-circuit heating boiler, since it can be both direct and mixing. The first option is characterized by adjusting the temperature mode by means of a burner, whereas in the second embodiment, not only the burner is used for these purposes, but also a mixer with a tracking drive. And if you are far from all these subtleties, it is better to trust the process of device of such a node professionals.

Regardless of the option of connecting the heating boiler you have chosen to arrange your home, any of them must necessarily be supplemented with an emergency scheme. It is thanks to the additional strapping that your heating unit and the entire system as a whole can fully function in the event that unforeseen emergency situations arose. As a rule, most often the boilers cease to work due to electricity supply interruptions.
Thus, today specialists with long-term experience in this field of activity offer 3 effectively working variants of emergency schemes.
This way of ensuring uninterrupted work is characterized by the use of battery devices or special uninterrupted rooms. However, this option is not always possible to realize, because not every owner similar machinery Regularly feeds its electricity. Therefore, if you do not want to get into the difficult situation, do not forget from time to time to check the performance of batteries and charge them.

An excellent solution will be a circulation pump of 12 volts, which means electricity is charged, without disconnecting from work, and when the power grid does not work, it works from the battery. Switches the machine, does not require any forced adjustment, it is inexpensive, it works for a long time.
In this case, the main heat tractor, which works at the expense of artificial pressure injection by the pump, is complemented by another contour, which operates through the natural circulation of the heat source. This system is connected immediately after the centrifugal pumping unit ceases to operate. However, it is worth understanding that a natural way to move hot water by the system will not be able to fully heat the room with a large area, so spend its wiring only in those rooms where there is a need to preserve heat.

Bypass for system
This option is the most optimal, but at the same time the most financially expensive. After all, for its device, it will be necessary to spend another contour, which will work during non-standard situations.
Here, in fact, all the subtleties of the connection of the thermal circuit along with the heating element. We hope our tips will help you create in your house as comfortable as possible. temperature conditions To accommodate!

The appointment of any heating system is to create a comfortable environment in the house. A favorable microclimate will not be able to achieve if the connection of the heating boiler is incorrect. Schemes of gas boilers of heating helps to connect this device with water supply and distribution networks, according to the established rules and specifications.
According to experts, a properly performed blockage of a gas boiler of heating or a device operating on another type of fuel allows the heating system to work more economically and efficiently.
The strapping of boilers, including double-circuit models, is performed by soldering. This method allows during operation to avoid leaks, in contrast to the use of fittings, when there are places with inaccurate mounting, through which the liquid coolant flows (read also: ").
Packing serves a paronite. It is forbidden to use packs, fum-ribbon or component products made of rubber. The fact is that rubber gaskets under the action of high temperatures can be dried and as a result practically overlap the passage in the pipeline, and the panel is easily flammable.
Lined with polypropylene pipes pipeline, such as in the photo, can withstand pressure up to 25 bar, are also not dangerous to him high temperaturesreaching 95 degrees Celsius.
The feature of the two-circuit boilers is that in the process of spending hot water, there is no parallel operation of both contours. This means that the blockage of a wall-mounted two-circuit gas boiler does not depend on the type of heating and is always the same. Radiators and coolant due to big size The pipes are cooled long enough.
There is another feature: if the binding of a two-kinning gas boiler is performed, then it is impossible to use the natural circulation of water. Many models have a special pump, because without it, after the generator stops heating, the movement of the coolant stops and the installation proceeds to re-heating, which takes up much longer time and eventually the radiators begin to uneven heat the room (read: "").
The heating level is regulated by radiators equipped with choke and jumpers (read also: ""). In obligatory in the second lines of the eyeliner, the cutting valve is mounted, and an air vent was placed at the top of the expansion tank. Returns the coolant to the boiler on the bottom line of the eyeliner.
When the binding of a two-door gas boiler is performed by the owner of the house independently, you need to prepare the following tools and components for working:
Forced-type instruments are characterized by ease of operation and are considered to be more comfortable.
The control of the heating unit is carried out automatically. Among the advantages it should be noted that for individual premises, you can set a certain temperature, due to the presence of sensors controlling the heating process.
For waterproofing each contour, an additional heat exchanger is installed. This will be required to combine open and closed systems. Installations related to separate type are required to be equipped with circular pumps, security system and cranes (drain and felicing).
How to connect a gas boiler, in detail on the video:
The design of the dual-circuit device is characterized by complexity. A reasonable solution is to appeal to a specialized gas organization. Her staff will quickly plug the equipment to the gas supply system.
Greetings, Comes! Today we have to learn how to assume a gas boiler: what elements should include a strapping, where to position them and how to fix it. I will figure out several of the most popular schemes for different systems Heating and water supply.
We have to disassemble the following scenarios:
With a high length of DHW layout without recycling, water has to drain long until it is heated. It is not only uncomfortable, but also consistently.
What elements may include the removal of the boiler heating?
| Picture | Name and function |
 |
Membrane expansion tank. Its task is to compensate for the increase in water or antifreeze in a closed heating circuit when heated. The tank is divided by half the elastic membrane, and part of its volume is filled with air (or protecting the walls from corrosion by nitrogen). With an increase in the volume of heat carrier, the gas is compressed, and the pressure in the circuit increases slightly. As a rule, the tank volume is taken equal to 10% of the coolant amount. The one, in turn, can be roughly evaluated as 15 liters per kilowatt power of the heating boiler. |
 |
Safety valve. Its function is to reset the excess of the coolant with a dangerous pressure growth in the circuit, preventing the pipe or batteries. Water is discharged through a drainage tube into the sewer. Frequent valve trigger indicates insufficient expansion tank. |
 |
Air road. It serves to automatically reset into the atmosphere of air stoppers remaining in the contour after draining the coolant. Air creates hydraulic noises and prevents normal circulation with a small hydraulic pressure. |
 |
Manometer Need to control the working pressure in the circuit. Sometimes instead of it uses a thermomanometer, showing pressure and temperature. The scale of the instrument should be marked at least 4 atmospheres (bar, kgf / cm2). |
 |
Outdoor expansion tank performs the functions of the expansion tank, air vent and safety valve in the open (i.e. working without overpressure) Heating system. The tank is communicated with the atmosphere and is often connected by a tap to the system of a rh3 to feed the contour. |
 |
Boiler indirect heating - heat insulated tank with heat exchanger for cooking hot water. The heat source is water or antifreeze of the heating system, circulating through the heat exchanger. |
 |
Circulation pump Provides forced circulation of the coolant through the heating circuit. The main characteristics of the pump - the pressure created by them and productivity. The power consumption of modern pumps is 50-200 watts and can be adjusted, which reduces and increase the speed of the coolant. |
 |
Hydrostroll -capacity with nozzles for connecting multiple heating circuits, combining feed and return pipelines. The hydroelectron allows you to connect circuits with different temperatures and a circulation rate by reducing their mutual influence to a minimum. |
 |
Coarse filter -sustainer with a filtering grid for water purification from large contaminants (first of all - sand and scale). The filter protects the thin tubes of the gas boiler heat exchanger from clogging. |
 |
Two- and three-way thermostatic mixersprovide coolant recycling, allowing you to create an additional circuit with a lower temperature compared to the main temperature circuit. The mixer shutter is controlled by a thermal head - the device changing the position of the valve depending on the temperature of the sensing element. |
What pipes can be used to connect the gas boiler to the heating system and for wiring the coolant?
Let's turn to common sense. All parameters of a properly designed autonomous heating system are absolutely stable and controlled by the owner:
When stopping the circulation pump, overheating and boiling the coolant is completely excluded: the heat thermostat is resetting the burner after a few seconds.
Conclusion: To connect the boiler and laying the heating, it is possible to use polymer and metal-polymer, the price of which is several times lower than expensive and durable copper, galvanized and stainless steel.
Threaded fittings for metalplastic are sensitive to the quality of installation and when the sealing rings are displaced, there are flows through several heating-cooling cycles. Polypropylene without reinforcement or with fiberglass reinforcement has an excessively high elongation coefficient: when heated by 50 ° C for each meter of the pipe to its length, 6.5 and 3.1 mm will be added accordingly. Therefore, from their use on heating it is better to refuse.
SAMI simple schemeallowing the installation of the boiler ... without strapping.
How? Everything is very simple. The absolute majority of electronic ignition boilers in the factory configuration include:
All elements of the strapping are placed in the housing, which turns the device into a full mini-boiler room.
At the request of the owner before the boiler can be installed:
The filter protects the heat exchanger from the garbage, but increases the hydraulic contour resistance, reducing the circulation rate and creating an additional load on the pump.
Boilers with piezorozhig and floor appliances are not mini-boiler, but just heating devices that require the installation of external strapping.
Elements:
Tip: Convection heating systems with gas boilers Function with DT \u003d 20 ° C (75-80 on the supply and 55-60 on the return pipeline).
So, with a boiler power of 36 kW, a reasonable minimum of pump performance - 0.86 * 36/20 \u003d 1.548 m3 / h.
Location: The security group is placed at the outlet of the boiler, where the temperature and pressure are maximal. Pump - in front of the boiler, at a point with a minimum heat carrier temperature (its reduction will increase the resource of impeller and rubber sealing gaskets). Expansion tank - anywhere in the contour.
The expansion tank can be mounted not closer than two bottling diameters to the impeller when it is installed before the pump and not closer to eight diameters when mounting after the pump. The removal from the impeller will not allow the circumstances arising during its rotation to create constant pressure jumps that reduce the resource of the tank membrane.
To protect against the formation of condensate, the heat exchanger is often mounted parallel base circulation circuit. With a low temperature of heating, it is diluted with a hotter coolant coming through mixing knot From the feeding.
What does the impunity of the gas boiler of heating look like with their own hands in the case of an open heating system with natural circulation?
Such a system is completely non-volatile and operates at atmospheric pressure.
Elements: All security group functions perform an open expansion tank. Pouring in front of the heat exchanger of the boiler is useful to supply the scope for a complete drain of water into the sewer or drainage well. Reset will be needed with prolonged departure or gas output and will prevent the system defrosting.
Location:
A pair of subtleties of the installation of a gravitational heating system:
It can be connected in several ways.
The hydroelectron is a common element of two contours:
How it works?
Parallel to the main contour radiator heating Or a small contour between the boiler and the hydraulic circuit is formed by a low-temperature contour with bypass and a three-way thermostatic valve.
The circulation pump causes water to continuously circulate on the pipes of the warm floor; New portions of the hot heat carrier are selected by a three-way mixer with feed only when cooledting the warm flooring is reduced below the target temperature.
Instead of a three-way mixer, a conventional thermostatic valve with a remote thermal sensor (capillary or electric thermocouple) can be used. The sensor is placed in a pocket on the rapid floor. The valve opens when the temperature of the coolant is dropped below the threshold level.
It is possible only when using a condensation gas boiler: classic boilers cannot work with a reverse of 55 degrees, since the cooling of the heat exchanger leads to falling on it. Gas combustion products contain, in addition to water and carbon dioxide, aggressive acids, quickly destroying steel or copper heat exchanger.
W. condensation boiler A different work scheme: Product of combustion is intentionally condensed on a separate stainless steel heat exchanger (economizer), giving additional heat and increasing the efficiency of the device. That is why the temperature of the return temperature of 30-40 ° C is not just allowed; It is a prerequisite for the work of the device.
The heating system includes two consistently connected circuits - radiator and intrapole heating. The first of them is used as a second.
What should be the blocking of a wall gas boiler that allows you to put the hot water system from it?
Elements: In addition to the security group, pump and expansion tank, the strapping includes an indirect heating boiler. The heat carrier from the heating circuit serves as a heat source for water heating.
Scheme:
What should be the strapping scheme of a two-kilt gas boiler?
Let's start with the Azov. The double-circuit boiler is equipped with two heat exchangers - for heating and DHW. Both heat exchanger - flow and controlled thermostats.
From the practical side, this means that the heat exchanger of the DHW begins to warm the water only at its consumption through the crane. Overheating and uncontrolled pressure growth can not be afraid; The expansion tank and the security group on the DHW is not needed.
The water supply voltage is connected to the inlet pipe of the water supply heat exchanger, to the outlet - the stamp of hot water, laying it on the mixers.
Hot water contour elements:
Heating circuit elements: The same as used for a single-mounted boiler.
Installing a small expansion tank on the DHW is practiced when the hot water is wiring with metal pipes. All types of polymer pipes due to the elasticity of the walls perfectly compensate for a slight expansion of water during heating.
How to organize water circulation in the GVS system?
Elements:
In apartment buildings risers in gVS systems With continuous circulation, 2-4 pieces with jumpers on the top floor or attic are combined. Heated towel rails are installed in the breaking break.
Features:
I hope that I managed to tell the reader to solve all the problems that may arise when installing the gas boiler. As usual, the video in this article will offer you additional materials. Waiting for your additions and comments. Successes, Camrads!
The task of the heating system is the creation of a comfortable microclimate in the house. The competent organization of heating determines the uniform distribution of heat around the perimeter of the living space, and protects the elements of the functioning unit from overheating. The capping of the boiler is the process of connecting equipment to hot water supply and distribution networks in accordance with the operating standards.
The boiler - the rod of the heating circuit and its type affects the choice of the strapping scheme. The main rule of installation of the floor boiler comes down to ban its placement in the top of the wiring pipelinebut. In case of violation of norms, a boiler that does not have conditions for air output will begin to create air traffic jams. Pipe leaving the boiler without the presence of an air vent must have clear vertical position.
The nozzles located at the bottom of the unit will "tell" about the presence of an automatic air vent, which is necessary for connecting to the heating network. They are provided in nasty electrical and gas models. This feature should be taken into account when strapping a boiler, since the wall-mounted monoblock models can cope with independently with the release of air masses.
Boilers are sold, both fully equipped and without additional elements. Required parts are purchased separately and included in the contour. Those who stopped at choosing heating with natural circulation, they will not use.
Suitable gasket from a paronite. The use of packles, fum-ribbons and rubber components are prohibited. They can light up, and the rubber will reduce the diametrical passage of the pipe, which will break the gas supply. Such pipeline initially, claims long service , It is capable of withstanding a pressure exceeding 25 bar, and a coolant of 95 degrees.
The boilers of this type do not have the function of heat supply control. The combustion of fuel cannot be interrupted, so in the event of a turning off the supply of electricity, the pump will stop responsible for the forced movement of the coolant. However, heating will continue, and pressure grow. Developing process disabling the entire system. To exclude such moments there are several types of emergency schemes, allowing to discount the excess heat. It:
For solid fuel boilers, the strapping plays an important role - a high-quality connection will allow you to create a self-regulating system. Therefore, the installation subtlety is better to entrust the skillful hands of experts.
It is necessary to pay attention to the principles of circulation of the coolant along the heating contour. It - - natural motion Coolant and contour with forced circulation. A distinctive feature These species are the presence or absence of a node forcing hot water to move.
In the system of natural circulation, the movement in a closed system occurs under the influence of physics laws. The process is due to the indicators of the difference in the density of water. This type of heating excludes electricity consumption.
Natural circulation system automatically adjusted can notAnd it will require the presence of pipes with a large diameter, which will affect the interior of the room and greater cost. If the network is subject to periodic voltage drops, the best option will be the organization of heating. The system is reliable in operation and does not require attention. The scheme of the natural movement is suitable for a small area, although it is currently considered the "past century".
Benefits of a system with natural circulation:
Forced circulation ensures the creation of the necessary pressure from and the account of the electric pump. The circuit with forced circulation is distinguished by comfort, since it is controlled automatically under the condition of stable electricity supply. For each room, it is permissible to select individual temperature parameters, controlling system sensors.
disadvantages Systems:
Any of the installation systems requires a certain number of additional details. The installation option on the primary secondary rings does not imply a large presence of fastening and compound elements, but instead they will need to install pumps for heating rings. A system consisting of a rings, together with an outdoor boiler, is complemented grebelkov- Manufacturers of heating , Uniformly distributing the flow of the coolant to the heating elements.
The efficiency of heating depends on the accuracy of the connection. General scheme Straps for boilers of all types, including solid fuel and condensing species, simple, and looks like this:
Now consider the difference of the heating scheme country house Using a two-door boiler.
This type of unit differs from a single-mounted analogue universal appointment: Supports degree of coolant mode in the heating circuit, and heats water For household needs. Single-mounted generators also indirectly heated water. The process of heat transfer from them occurs during the passage of the coolant through the secondary heat exchanger.
The difference between the dual-circuit boiler consists in direct return of thermal energy water. Its feature is that at the cost of hot water, the coolant is not heated. Parallel work of two contours is excluded. Practice has shown that for houses with high-quality thermal insulation, and therefore, with thermal inertia, the mode of functioning of the boiler is not fundamental. And the heating scheme will be the same with any type of heating. Radiators and coolant provide for long cooling. A similar result is due to the choice of radiators. with a large capacity and wide pipe diameter. A large amount of hot water can be obtained by combining one-circuit design and heating column. For houses with lots of square. m. The work of the boiler has no fundamental importance, and the boiler heating schemes will be similar.
Two-kotel do not design in combination with a natural circulation system- After stopping the heating of the coolant, the movement will quickly stop. The reheating process occurs for a long time, and heat in the radiator is unevenly distributed. However, most models are equipped with circulating pumps.
Classic option The strapping of boilers with a two-pipe scheme looks like this. Hot water Rises into the feed pipe covering the house at the top. Then the coolant passes through the connected risers with heating devices, not blurring the riser completely. Radiators are equipped with a jumper and choke needed for heat adjustment. Need cutting valve on the second liner line. The air vent is attached at the top of the expansion tank loop.
By lower connection Systems The coolant returns back. The advantage of the scheme is to work in natural circulation mode. Accepted collectors will be a pipe along which the coolant moves to the upper bottling.
With the open heating system, they are not used. Valve Purpose - eliminate boiler from damage In case of a sharp increase in pressure. Usually, the valve is forgotten or installed a model or a security group with other characteristics.
During the reaction of the valve, part of the water flows out of the system, which ensures pressure reset and protection. You should not insert the cutting tube to the sewer, since the cause of pressure reduction will not be clear. You can do the funnel. By the way, there is no need to throw a septic tank in the coolant.
Air road. The item must be put immediately after mounting the boiler to avoid "delighting". Often, they forget to just open. It is also typical for wall-mounted options with factory function. By the way, the circulation pump is also ventilated.
The air worker should stand strictly upright up. In the case when it begins to leak, it has a shut-off valve, so the replacement for a new one will take a couple of minutes.
Circulation pump. The pump will work properly only with the horizontal position of the axis, and this provision will noticeably extend the "life" to bearings.
The mechanism is desirable to protect against dirt and garbage from the outside. Separately sold mesh filters
Radiators. Shortcomings when connecting the panel radiator to the coolant. The radiators project involves connecting the feed pipe to the inner bubbling, which is almost in the center, and to the extreme - in the inverse tube. The reverse order of the compound will reduce the heat transfer of the radiator twice. By the way, the decorative screens violate the heat exchange by 10-20%.
Competent installation and loyalty of power calculations will help create maximum comfort for accommodation in country house in any season.
