In order to provide your home or apartment with economical heat and hot water at any time of the year, you can install and connect a double-circuit gas boiler, but only specialists know how to do it correctly. Serious problems can be solved with the help of one element. And therefore in Lately Such units are very popular among owners country houses. Connecting such an installation is not an easy process, but if you figure it out, you can do everything yourself.
In most cases, there are units that are capable of heating 6 liters of water in one minute. This indicator can be considered quite good. True, it is only possible if you implement correct installation installations.
The operating principle is based on the presence of two circuits separate from each other. The first is responsible for heating the house, and the second is responsible for hot water in the tap.
To connect the installed boiler, you need to take into account the presence of several systems in the room:
Installation and connection of a dual-circuit system begins with mounting it on the wall. For this purpose, special brackets are used, which in most cases are supplied with the equipment. The main thing to consider is that the fasteners must be in an ideal horizontal plane, and therefore you must have a level.
After installing the fasteners, the boiler itself is hung on the wall. All this is done with your own hands. To be on the safe side, to prevent any mistakes, you can first watch several videos, of which there are many on the Internet. They show the installation of different systems.
There are several rules that must be followed when choosing a room to install the unit:
Usually the connection of similar devices is the same. The only thing that may differ is the location of the pipes. But this does not happen often.
Due to the fact that there are many different models of gas boilers on the market, it is difficult to talk about all specific installation schemes. We can only highlight the main components that must be present so that the unit is not only easy to install, but also to use in the future.
Key points:
Installation must begin with the installation of a shut-off valve and filter on the water supply. This will help only purified liquid pass through the unit, which in turn will significantly extend its service life.
The valve is necessary for situations where you need to close the water supply to replace the filter, clean the system or repair.
After this, the heating system pipes are connected and hot water. There is nothing complicated here either. First, the shut-off valves are connected, and then the connection to the boiler occurs.
A home wall-mounted boiler is necessarily equipped with a pump, which ensures uniform heating of all radiators in the room. This device requires special strapping. Wall models are volatile, and therefore any power outage immediately reduces operating efficiency. Floor-standing models can work without such pumps, since they are equipped with special elements to create natural pressure.
It is not uncommon that many private houses do not have centralized heating and water supply. For this reason, owners have to resolve such issues themselves. Wall mounted ones can come to the rescue gas boilers. How to correctly install a wall-mounted gas boiler with your own hands? How much does it cost to install a gas boiler?
Today they are presented on the market in a huge number and variety of brands. There should be no problems with their choice. However, it is worth deciding how to install the boiler - on our own or with the help of qualified specialists? Last option not bad, but you will have to spend extra money to pay employees.
The room in which the boiler will be located must have a window for ventilation. The door to the room should open outward. The room must have an area of more than four square meters. The ceiling should be at a level of two meters or more. Concerning doorway, its width must be at least 800 millimeters. Required condition for the boiler room - the presence of a working ventilation duct. Often wall-mounted boilers located in utility rooms, kitchens or pantries.
Another important condition is to cover the wall where the unit will hang with non-flammable materials. This action will eliminate the possibility of a fire that could occur when a spark hits flammable materials. Modern non-flammable products will harmoniously fit into the design of the room without spoiling the interior.
When purchasing a boiler, you need to obtain an official certificate, because in the absence of this documentation, registration of heating equipment will become almost impossible. The certificate will also allow you to connect the equipment to the gas supply system.
When choosing a location for the unit, you need to consider installing a hood for a gas boiler. Old chimneys can be used, but if they are not available, new chimneys will need to be installed. Most often, the combustion product removal system comes complete with the boiler itself.
Compliance with such rules for installing a gas boiler is vital.
Some tips for installing boilers
One of the most important stages when installing gas heating boilers - their connection to the gas supply system. In order for the regulatory authorities to give permission for it, it is necessary to carry out the installation and installation of the gas boiler strictly in accordance with the recommendations and requirements contained in the technical passport. Otherwise, you will have to redo something, if not everything.
When installing a Navien gas boiler » , as well as installation of the Immergaz gas boiler, it is important to check whether its power corresponds to the power of the entire heating system. When connecting the boiler to an old heating system, it is imperative to clean and flush all the pipes, which will eliminate the possibility of clogging in the near future.
It is necessary to think through the entire installation scheme of a wall-mounted gas boiler in advance. It must provide water treatment to supply the hot water system. The entrance to the unit must be equipped with a cleaning and metal-collecting magnetic filter.
One of the worst enemies of a gas boiler, and indeed the entire heating system, is corrosion. Therefore, to avoid its occurrence, it is better to install a closed circuit that will prevent air from freely entering the system.
Before actual installation gas equipment you need to take care of the chimney hole.
It will be much more convenient to install if you use a special cardboard template. With its help it is easy and without special effort Marks are made for all fastenings and the chimney. When the location for the boiler is finally chosen, you should attach the template to the wall. It must have points of attachment lines and places where the wires will be connected. These important marks should be transferred to the wall with a marker or colored pencil. Then the template can be removed.
The next step is drilling holes for the dowels. To do this, you should choose a drill that has required diameter. Each dowel must be selected in accordance with the material and thickness of the wall. After the holes are ready, metal corners are attached to the wall.
Then you need to remove the top cover of the unit. Now you can safely attach equipment to hanging corners on the wall. Before installing brackets, you need to make sure that all chimney fittings have the right sizes exactly according to the instructions, otherwise there will be problems later. The bracket to which the gas boiler is attached must itself be very securely fixed to the wall. This is the most important point.
It is important to remember that depending on the type of wall there are various ways fastenings Exist different types fastening installations, each of which is designed for installation of a certain type of unit and type of load.
During installation, it is important to ensure that no debris gets inside the fan. The pipe through which combustion products will be removed must be at least two centimeters away from the wall surface.
Before installing a wall-mounted unit, you should obtain in advance:
First you need to close the water supply using the valve. After this, you can connect the boiler and pipeline using a threaded coupling. To achieve the tightest fixation, be sure to use tow. The unit must first be connected from the end side. The hot water supply is connected to the top pipe of the unit, and the return to the bottom pipe.
The distribution box of the unit must be connected to the power cable, and a safety contact outlet must be provided from the switch.
Thanks to the cable, power is supplied to a powerful boiler, and therefore each fuse should not exceed three Amperes in power, or the fuse should have a rating lower than the current rating required for high-quality use of the boiler. At the end of this type of work, you need to connect the gas equipment to reliable grounding.
As you can see, installing a gas boiler on your own is quite feasible in as soon as possible without extra costs time, effort and money. You can study the installation of a wall-mounted gas boiler with your own hands in the video in more detail. For example, the most frequent questions have become regarding the installation of the Danko gas boiler, which is gaining popularity.
The cost of installing a gas boiler is much lower than the cost of calling specialists. In addition, the work is carried out quickly, and the skills acquired during installation will be useful in the future.
You have purchased a new gas boiler for your private home and it’s time to take its place in the furnace room. To do this, you can hire a specialized company or contact the appropriate service. But the cost of installation in this case will significantly hit your wallet, while there is an opportunity to reduce the cost of the process. Yes, some operations can only be performed by licensed organizations, but this is only half the work; the rest can be handled independently. Here we will talk about how to install a gas boiler in a private house from start to finish.
Since the installation of new gas-using equipment requires compliance with certain rules, it is worth ordering all work that requires a license from the gas service:
You can complete the rest of the steps yourself. First you need to get gas from the service technical specifications for installation of gas equipment. Check them out or make a copy and immediately order project documentation from them. When it is ready, it will need to be approved by the gas service. As you might guess, this procedure is a pure formality; after its completion, a team will come to your home and install the gas boiler in terms of its connection to the fuel line, about which a corresponding report will be drawn up.
All that remains for you to do is to complete the piping and connection to the heating system and laying electrical networks. Here you will have the opportunity to save money, either by doing everything yourself or with the help of familiar plumbers. The last stage is the final paperwork.
It's just short description one of the possible algorithms for solving the problem, but in reality not everything is so simple, because gas boilers must be installed in compliance regulatory requirements, it wouldn’t hurt to familiarize yourself with them at the stage of choosing a heat generator.
First of all, it is necessary to take into account all the requirements for the room where the heat source is supposed to be placed. The options are:
In the kitchen, installation standards allow the installation of a floor-mounted or wall-mounted unit with a heating capacity of up to 60 kW. Equipment with ratings from 60 to 150 kW can be installed in a separate room on any floor, and from 150 to 350 kW - only on the first or ground floor, in the basement or outbuilding. At the same time, it is important to observe the dimensions of a separate room or an attached part; they cannot be smaller than specified in the standards. The minimum standard height of such a room is 2.5 m for any power within the specified limits.
Note. The thermal power values specified in the standards and affecting the installation conditions of the boiler are the total power of all units in the boiler room, including those working for the needs of domestic hot water.
For heat generators with a capacity of up to 150 kW, in accordance with the standards, the smallest volume of the room for installing a gas boiler is 15 m3, in addition, for each kW of water heating equipment, 0.2 m3 is added to this volume. If the total indicator of all units exceeds 150 kW, then the dimensions of the room are not standardized. But the installation rules apply and safe operation boilers, according to which it is necessary to maintain technological gaps between the units and the walls of the room; they are adopted for reasons of ease of maintenance and access to all systems in the boiler room. The dimensions of the passages in accordance with the rules are as follows:
For the kitchen, where it is allowed to place not too powerful heating equipment(up to 60 kW), there are not the most stringent requirements for the installation of gas boilers. You just need to comply with the volume standard given above, and also ensure air exchange in the amount of 3 times in 1 hour. Additionally required to submit supply air for fuel combustion, its consumption for each unit is indicated in technical specifications. This standard applies to all types of boiler houses.
Note. For heat generators with a closed chamber, the installation standards for gas boilers do not force the supply of an air mixture for combustion, since they take air directly from the street through a coaxial chimney, which will be discussed below.
IN regulatory documents It is proposed to organize ventilation for the boiler in the kitchen using an exhaust shaft and a supply grille built into the front door. The flow area of this grid is also standardized; its area cannot be less than 0.025 m2. In the same way, you can arrange air exchange in individual combustion chambers. Feeding difficulties fresh air may occur in basements or basement floors, it is possible that to comply with technical conditions it will be necessary to install a special supply fan.
In boiler rooms located on the first, ground floor or in an extension, window openings with a glazing area of at least 0.03 m2 are needed for each cubic meter of room volume. The attached premises also have requirements for fire resistance of walls, separate foundation And entrance doors. In addition, the extension cannot be built on the front facade of the building, and during construction it is necessary to retreat 1 m horizontally from the nearest window or door.
It should be noted that the requirements for a gas boiler located in wooden house, are identical to the standards for buildings made of other materials, that is, the rules for installing boiler rooms are the same for all buildings.
When suitable premises chosen and executed according to it project documentation, you can begin to install the heat generator in place yourself. To do this, you will need a connection diagram for a gas boiler in a private house, which must be present in the project. It shows the installation location, the distance to all enclosing structures and the technical requirements for the work.
Often, the installation of floor-standing gas boilers requires the construction of a foundation. In many cases it is not needed, for example, when the room has a high-quality screed and the weight of the unit does not exceed 50 kg. If the weight of the equipment is greater than this value, then you will have to prepare the foundation. To do this, you need to destroy the existing screed, pour a cushion of crushed stone and compact it thoroughly. Then tie a mesh of periodic profile reinforcement with a diameter of 8 to 12 mm, lay it on the finished base and fill it with concrete.
In order to withstand the technology of installing gas boilers, the dimensions of the foundation in plan should be 50 mm larger than the dimensions of the equipment, and in height it should protrude 50-100 mm above the level of the screed. Complete hardening concrete slab will take you at least 2 weeks, this must be taken into account when planning the work.
Next, a fireproof asbestos or metal gasket is placed on top of the foundation and a heat generator is placed on it, adjusting the legs of the unit so as to maintain a clear horizontal line. After this, using the gas boiler installation diagram, it is connected to all engineering networks except for the fuel line. This connection, as mentioned above, is carried out by a licensed organization.
To install a wall-mounted gas boiler in a private house, you do not need a foundation, but a solid foundation in the form of an outer wall that can support the weight of the unit. First of all, markings are made on it, showing where the heat generator itself will be suspended and where the chimney pipe will exit. Then, using a hammer drill, a through hole is drilled in this place, into which a metal sleeve is inserted.
There is no particular difficulty in hanging a wall-mounted gas boiler. If the action takes place in the kitchen of an apartment or house, it is necessary to take measures to protect the furniture from debris and then begin the fastening process. Difficulties may arise when installing heavy units, whose power reaches 120 kW; here you cannot do without an assistant.
Note. When a wall-hung boiler is attached to a wall made of flammable material, a special bracket must be made to allow a clearance of 45 mm between the wall surface and the rear panel of the heater. Also, a sheet of non-flammable material should be attached to the wall, acting as a protective screen.
The last thing to do is piping the gas boiler and installing the chimney. Here it is necessary to compactly place taps and other fittings under the body of the heat generator so that everything looks neat and at the same time it is possible to disassemble or change any element. Therefore, when the heating circuit in the house is made of polypropylene pipes, then it is better to use bronze taps and mud pans, and plastic pipes connect via threaded adapters. In this regard, it is somewhat more difficult to install a double-circuit gas boiler, where you will need to lay pipes for hot water supply and correctly connect them to the appropriate pipes.
In essence, the requirements for the chimneys of floor-standing and wall-mounted gas boilers are identical; the difference may be in the design of the flue itself. It depends on the design of the heat source:
A traditional chimney for a gas boiler is installed in the thickness of the wall or suspended from the outside of the building. The cross-section of the outlet pipe from the unit determines the diameter of the entire chimney; it should be the same size, or better yet, 20-50 mm larger. The horizontal section connecting the boiler to chimney, ideally made with a length of 1 m, the maximum permissible length is 2 m.
Below the insertion point, a door is required for cleaning and internal inspection, and the blind end vertical pipe equipped with a condensate drain system. When installing the chimney of a gas boiler, you must remember that it is not allowed to cover the pipe outlet with umbrellas, deflectors, weather vanes, and so on. In accordance with the regulations, only a narrowing nozzle can be installed.
Unlike traditional exhaust ducts for combustion products, it is much easier to install a double-walled chimney for heat generators with a closed chamber. Having done in external wall a hole of the required diameter and having built a metal sleeve into it, a coaxial chimney is installed, which is a horizontal double-walled pipe of a certain length. The only condition that must be met is a slight slope towards the smoke exit. This is done to prevent condensate formed in the air duct from flowing into the boiler.
So, installing and piping the boiler with your own hands is not an easy task, but it is quite feasible. It will take a lot of time and patience to complete all the documentation, but the installation work itself will take a maximum of 3-4 days, or even less. It is important to prepare well and purchase in advance all the missing elements of the strapping scheme, as well as fasteners.
When purchasing a gas boiler, many people want to save money and install it themselves. Is it possible to do this? In some cases, yes, but it still won’t be possible to do without specialists. After all, gas is an explosive fuel, and its connection by persons without a special license is illegal. The remaining work on installing a wall-mounted gas boiler can be carried out without the involvement of specialists, but all the requirements of the relevant SNIPs should be taken into account.
Please note that not all manufacturers allow the possibility self-installation. For example, the companies Ariston, Viessmann, Bosch recommend using the services of specialists only from their service centers.
BAXI, Ferroli, Electrolux are more loyal to the issue of installation and allow installation of gas wall-mounted boiler heating with your own hands.
Therefore, before purchasing a particular model, read the documentation and find out whether you can install this unit yourself.
Note! First thing before starting installation work a project should be developed and approved by the relevant supervisory authorities.
The requirements for the room in which the wall-mounted gas boiler is located depend on the type of combustion chamber: open or closed.
Open combustion chamber uses air for the combustion process from the room in which the heating system is located, and exhaust gases are discharged through the chimney. Such gas boilers require a certain volume of air, otherwise the gas does not burn completely and forms toxic toxic substances. Therefore, the operation of units with an open combustion chamber is permissible only in a separate room, which is called a boiler room or furnace room. It is necessary to provide a window for ventilation with an area of at least 0.5 m². The walls of the boiler room must be finished with fire-resistant materials.
The volume of the combustion chamber depends on the power of the gas boiler:
The connection between the boiler and a conventional chimney is made by using iron pipe a certain section. She must be resistant to influence high temperatures and toxic combustion products. When installing a connecting pipe, the following rules must be followed:
Closed camera type combustion suitable if it is not possible to install a separate furnace. These boilers come with a coaxial chimney, which is quite easy to install yourself. It is a structure of two pipes, one of which is inserted into the other. At closed type Combustion chamber air enters from the street through an external pipe, and combustion products exit into the atmosphere through an internal one.
If you have chosen a gas boiler with a closed combustion chamber, keep in mind that such equipment will require an electrical connection to provide power to the fan, which creates air flow through the coaxial chimney.
Gas units equipped with closed combustion chambers are considered safer and more environmentally friendly, so they can be placed in the bathroom, kitchen or pantry.
Before starting work, be sure to read the manufacturer's instructions. installation instructions for a wall-mounted gas boiler, since different models may have their own nuances and installation subtleties. If this is not done, incorrect connection will lead to all sorts of leaks or to the fact that the boiler will not be able to work at all.
Wall installation
The first stage involves mounting it on the wall. The boiler is hung on a special bracket, which the manufacturer usually puts in the kit along with the device. Sometimes it happens that the fasteners from the kit do not fit, then you have to select the appropriate parts yourself. Also, when installing a gas unit, the type of wall is taken into account - fastening elements are selected depending on it.
The bracket is mounted in such a way that it can support the weight of the equipment and ensure a level position.
The section of the wall located behind the unit must be protected with fireproof material. The wall-mounted boiler should be installed so that the unit is no lower than 80 cm from the floor, and the gap between its rear surface and the wall is no less than 5 cm.
Note! A special cardboard template will help you with the installation. On it you can mark all the necessary fastenings and connections to the chimney. The template is applied to the wall and all marks are transferred to the wall. After this it is removed.Connecting heating and plumbing
The second stage is connecting heating and water pipes. Their number depends on how many circuits there are in the boiler. Before installation, do not forget to remove the plugs from the pipes. Filters should be installed on the pipes through which water from the heating main will flow to prevent the system from clogging with dirt or debris.
The quality of the water is important - if it is hard, you will have to install treatment equipment, for example, polyphosphate dispensers.
The boiler pipes are connected to the pipelines using a threaded coupling. For tight fixation, fum tape is used.
Connecting the boiler to gas
Only a gas service specialist or an organization licensed to carry out such work can complete the third stage - connecting the wall-mounted gas boiler to the general mains.
Self-connection is illegal and can also lead to irreparable tragedy. Therefore, first of all, contact the gas service. There, technical connection conditions will be developed specifically for your equipment.
Gasification can be carried out underground and aboveground. For underground pipes, polyethylene pipes are used, which are very resistant to corrosion. The above-ground method involves the use steel pipes, which enter the structure next to the location of the gas boiler at a height of 1.5 m from the floor.
If there are several in the house heating devices, gas is supplied to each of them separately. It is prohibited to lay a highway indoors.
All pipeline connections are sealed using paint or tow. It is necessary to install a gas filter on the tap, which protects the boiler from debris and condensate.
Electrical connection
The fourth stage is connecting the unit to electricity. Many modern models wall-mounted gas boilers are equipped with a complex automation system. It allows you to control the operation of the boiler without owner intervention, and also monitors safety.
Double-circuit units are produced in two versions: with a socket and with a cable for connecting to the machine.
If you purchased the unit with with a regular fork, then it should be placed closer to the outlet. According to safety requirements, it should be located next to the boiler and not under it. This is necessary to avoid a short circuit, which could cause coolant leakage from the device.
The gas unit requires mandatory grounding. To do this, purchase a point grounding kit, which can be located in the basement of the house or next to it.
In order for the automation to serve for a long time and not fail, it is necessary to provide the unit with a stable voltage without significant drops. If this condition is not met, you will have to buy a stabilizer.
For details on installation and connection of communications to a wall-mounted gas boiler, watch the video.
The first start-up of a wall-mounted gas unit must be carried out by a specialist. He will set the boiler to a certain mode and check that it is operating correctly.
Before starting, the unit is slowly filled with water until its pressure in the system reaches 2 atmospheres. The tightness of all existing connections is carefully checked. In progress commissioning works You can ask a specialist all your questions about the operation of the heating device.
If the boiler is working correctly and everything is in order, sign certificate of commissioning of the unit.
The task is not easy. The boiler cannot be hung haphazardly, since the safety of the people living in the house often depends on how correctly the wall-mounted boiler is installed.
This means that the installation of this device is carried out in strict accordance with technical requirements and standards adopted in Russia at the legislative level.
That is why installing a wall-mounted boiler with your own hands is an extremely labor-intensive and difficult process for a beginner.
Before the owner of the house starts, you will need to collect some documents:
Gas heating equipment is installed in accordance with developed and approved technologies that ensure the safety of its operation.
If all these requirements are met, then there is no doubt about the reliability and fire safety of the system. gas heating. It should be kept in mind that the heating system must be regularly maintained by employees of the city gas service.
