A device that uses natural gas for work is considered the most profitable option for a water heater. If there is a need to replace the old column with a new one, the owner of the equipment must know what documents will be needed for this and what work needs to be done.
When is a replacement necessary?
Replace the old column with new equipment if:
- The device does not turn on at all.
- The main nodes of the column are out of order.
- They want to replace the obsolete model with a more modern one.
Important Nuances
- Installation of a gas heater should be handled by professionals who can work with gas equipment.
- If the water heater is in the bathroom, as is often the case in old houses built in the 50-60s, it is not necessary to transfer it, although the installation of new columns in such a room is not recommended due to insufficient volume (it should be at least 15 m3) and lack of a window.
- It is important to make sure that the ventilation is adequate.
- If you want to hide the new column behind the decorative panels, you should make sure that they are non-combustible and easily removable.
How much does a replacement cost and what does the cost depend on?
On average, you need to pay about 3000-5000 rubles for installing the column. Depending on the model and manufacturer, the price can be either less or higher. Separately pay extra for the dismantling of the old apparatus (it costs about 300-800 rubles).
The costs of replacing the column include calling a house specialist to disconnect the equipment from the communications, dismantling the column, and also installing and connecting a new device. Also, the master takes a fee for the work on setting up the column.
The cost of work will be higher if:
- You need to additionally buy any materials for installation.
- It is necessary to carry out additional plumbing work.
- Chimney replacement required.
- It is necessary to replace the gas valve.
Required Documentation
In the case of installing a new column instead of the old one, the following documents are required:
- A copy of the project from the Housing Office, which shows the location of the column, features of gas and water supply, as well as smoke removal.
- Passport to a new column. If the device has not yet been purchased, you can simply specify the model.
- Act on the condition of the chimney.
- Application to the gas service on the need to replace equipment while maintaining the same installation location.
- Application for permission to work on the gas pipeline.
Dismantling the old column
Column replacement work begins with the dismantling of old equipment:
- First, turn off the gas supply and unscrew the gas hose.
- Next, shut off the water supply by turning the appropriate tap.
- After that, the column is disconnected from the chimney.
- As soon as the equipment is completely disconnected from communications, the column is removed from the mounts.
What can be the subtleties in installing a gas column? What general rules and regulations should be observed when replacing a gas column? After all, you simply must know the main points. Gas is gas, negligence and negligence in dealing with it end very poorly. In this article we will consider the procedure for the replacement and installation of a gas water heater. Consider step by step instructionsHow can I replace the gas column myself.
- The procedure and rules for replacing a gas column with your own hands:
- Standards and requirements governing the installation of a gas column
- Dismantling the old column
- Tools and materials
- Installing and checking a new unit
Standards and requirements governing the installation of a gas column independently
Note! Immediately make a reservation that all types of work related to gas supply, i.e. supply of a gas pipe, installation of tees, stopcocks on a gas pipe, etc. Only organizations with a corresponding special license carry out it. Ignoring this provision in the best case will result in a substantial fine and severe headache.
All gas column installation work can be divided into two categories:
- installation from scratch, ie she was not there, but you decided to deliver;
- replacing the old column with a new one.
In the first case, a design and supply of a gas pipe to the location of the future water heater is necessary. All these works are the lot of the gas industry in your area or company that has a license for the corresponding type of activity. You can’t do without it. In this case, do not try to do anything yourself. This is not smart, because you risk life and property yourself, and when you install a geyser in an apartment, you endanger others. And with the state it’s not a hand to play such games, the wrong weight category. Therefore, entrust these works to people authorized by law for this type of activity.
If the project is ready, everything, in coordination then, having completed part of the work properly, you can save a significant amount. Any work that you decide to carry out on your own must be carried out clearly in accordance with the requirements of the approved project, if this is not done, the gas economy will not accept this gas water heater.
Note. All work on installing gas units begins only when you receive a project with all the necessary permissions and approvals.
All gas column installation standards are governed by the following acts:
SP 42-101-2003 "General provisions for the design and construction of gas distribution systems from metal and polyethylene pipes"
SNiP 42-01-2002 GAS DISTRIBUTION SYSTEMS
For more information on installation regulations and rules, please
Whatever the reader’s tiresome with many clever words, we give the basic norms for installing a gas column, which are presented to the proposed installation location:
- The room in which the column is installed must be at least 7.5 m3 in volume.
- The room must have ventilation (window, window, etc.).
- The ceiling height in such a room should be at least 2 m.
- The room should have a chimney with a diameter of at least 120 mm (at the same time “stuffers” in apartments do not belong to those).
- The pressure in the water supply should be at least 0.1 atmosphere.
- It is forbidden to install geysers in bathrooms.
- The column is mounted on a wall made of non-combustible materials; installation above a gas stove and at a distance closer than 10 cm to it is prohibited.
At the same time, those columns that are installed in the bathrooms, in accordance with the technical standards in force at the time of installation, its operation in the future is allowed. That is, the law does not clearly prohibit its further exploitation. And that means replacing with a new one does not prohibit. And does not require transfer at the expense of the user.
If all these requirements for the installation of a gas column are feasible, then you can order a project. The exact installation location and other data will be displayed in the project.
Dismantling the old column
Since we have considered the basic requirements and norms in general terms, if everything complies, we can proceed to replace the gas column. And you should start with dismantling. This can be done with your own hands while saving from 300 to 800 rubles.
We start replacing the gas column by shutting off the gas access to the column by closing the tap at the end of the gas pipe. Using an adjustable spanner or an appropriate size open-end wrench, unscrew the hose fixing nut (rarely, but there is a way to supply gas using a metal pipe). Unscrewing the hose to damage the gas pipe is quite difficult, but with the "ancient" connection method, i.e. a piece of metal pipe, quite real. Especially if the junction has been painted over for years. In this case, do not use excessive force; use a modern solvent specifically for this work to remove paint. While spinning, hold the gas pipe with the second adjustable wrench, so there is less chance of damage.
After disconnecting from the gas pipe, remove the hose (pipe) from the point of entry into the column. If the hose has changed not so long ago and its condition is satisfactory, then it can be reused when you connect a new column. If there is a suspicion about the reliability of the hose - get a new one. When buying, take a certified and proven hose, yet it is gas and buying a cheap hose from a non-known manufacturer is not appropriate here.
The next dismantling action is to shut off the water supply system. If taps are provided to turn off the speakers, overlap them. If this is not possible, turn off the supply to the apartment. In the case of the latter option, before installing a new column, purchase two faucets at the inlet and outlet of the water from the column and install on the pipes in the place where the connection will be made. In the future, this will facilitate its maintenance.
After disconnecting the column from the water supply, remove the connecting pipe from the outlet of the column and remove it from the chimney. The column is disabled, now it can be removed from the wall mount. The mounting platform is free, you can begin to install the new unit.
Installation and start-up of a gas water heater
At the initial installation, it is better to entrust the gas connection to the connection and verification, with the act of registering a gas water heater. If the old column changes, you can do all the work yourself. But there are two nuances, if you doubt your ability to install a gas column correctly - trust the specialists, the wallet will be slightly thinner - but the nervous system will remain unaffected and, ultimately, the benefit will be yours.
If you decide to do everything yourself, you will succeed, the main thing is to do everything slowly and progressively. But even in that case, a representative of the gas economy cannot be dispensed with, he must register a column. Perhaps the best option is the situation when you do all the connection work yourself, with the exception of work related to gas. In this case, save a significant amount and there should be no problems with the gas service, as connection to the gas main will be carried out by their representative. We will consider this option.
Tools and materials
Before installing a gas column, you must purchase and have the following materials:
Galvanized pipe or corrugation, not thinner than 1 mm. If it comes with the column - great. If not, measure the diameter of the outlet of the boiler of the column or look in the instructions and purchase the appropriate pipe.
Get a ring - a socket for arranging the entrance to the chimney, also corresponding to the size of the corrugation.
If you plan to install a geyser in the house, and you need chimney equipment, you will need an asbestos or metal pipe, with a diameter of at least 120 mm, you can have more. It is not less than 2 meters long, more is possible - traction will be better.
Typical gas hose, hose size will depend on your conditions, i.e. the distance from the end of the gas pipe to the entry into the column. Pay attention to the type of thread at the inlet to the column, the hose tip must be suitable, it must match the type of thread, external / internal and diameter ½ "or ¾". The diameter of the fixing nut on the hose is ½ ”and if an inlet to the ¾” column is required an adapter (coupling).
It is better to prepare the place for connecting the water supply in advance, so you need only two connecting hoses of the required length. You can make connections using metal-plastic pipes, as you wish. In the latter case, determine whether couplings are needed to match the dimensions of the pipe and the place of connection and thread (external / internal).
Dowels for mounting the column on the wall.
If a coarse filter is not installed in the house, we recommend installing it. The service life of the new unit will directly depend on the quality of the water.
Tools for gas column replacement:
- Depending on the complexity of the work and material - a punch with a set of drills and chisels, a drill with a drill on ceramic tile.
- Adjustable wrench (2 pcs.).
- Open end wrenches 27/30 and 32/36.
- Tow and sealant of the Unipak type.
Installation and check of a gas water heater:
In this description, it is understood that the water supply and the presence of the chimney have already been implemented. At the installation location of the gas column, mark the points for mounting the mount. You must calculate the height of the column in such a way that the connecting pipe (corrugation) has a vertical length from the column outlet to the outlet of at least 50 cm, if the height of the room exceeds 2.7 m - 25 cm. At the same time, the installation height of the gas column is not should give children free access to the device. Also measure the distance between the mounting holes on the speaker casing. After you calculate the installation location of the dowels with a hammer or drill, it depends on your conditions, make holes and install hooks. The column can be hung on the wall.
Now, using connecting hoses or PVC pipes, we connect the water supply to the inlet of the column output. The use of a hose is convenient because at the connection points no tow or FUM tape is required. Connect the tap in series cold water with a gas column inlet, indicated in blue. In the same way we connect the hot water outlet to the tap (marked in red). We open the faucet of cold and hot water and see if everything is tight with us. If a leak is found, carefully squeeze the hose fixing nuts. Without extra zeal, as you can crush the rubber gasket - seal. The connection by means of pipes will need to be untwisted in places of leaks and twisted the tow with a sealant or tape FUM.
After we achieve the tightness of the water supply, you can go in two ways: either call the gasman, or install the gas column yourself in full at your own peril and risk. You decide.
If the second option, then we take a gas hose and fasten it to a gas tap. After that, connect the other end of the hose to the inlet in the column. We clamp without extra effort, no matter what crush the paranitic gaskets. We take a soap solution, we smear “from the heart” the joints around the entire perimeter, open the gas supply valve and carefully observe if there are any bubbles. If there is - squeeze the nut a little, and smear again. So until we achieve complete tightness.
So, we have a tight connection of water and gas. The next step is to install the corrugation. Everything is much simpler here, on the one hand we put on the column outlet, on the other we insert it into the chimney outlet.
We insert the batteries into the column, open the hot water tap and adjust the water temperature according to the operating instructions of the column. We use it.
And the last one. Usually in large stores a connection service is also organized. Ask when buying how much it will cost to connect their specialist. It will be cheaper or even free, while there will not be any issues with a column guarantee. Yes, and registration in the gas sector will be held without unnecessary friction.
If this is not available, I still recommend entrusting the gas hose to the gasman (the cost of installing a gas column for such a connection is several times less than the complete dismantling and installation), and he is pleased (he will earn money) and there are no complaints about you. Plus, the guarantee is safe and sound. But it’s up to you to decide.
The step-by-step article presents how gas column replacement with observance of order and legality in the structures of gas mountains. Values \u200b\u200bof all types of work in Ukraine and Russia are given.
What you need to know when planning replacement of a geyser, which has served its resource? The main feature of the problem is compliance with the rules and the rule of law in its solution on the territory of Ukraine and Russia. The useful information of such a solution guarantees safety and success.
How did the problem originate?
In our state, geysers are an attribute of the Khrushchev era. They were installed 40-50 years ago in low-rise buildings and private houses.
All columns had the same design capacity for each individual building. But, over time, they were replaced with newer and with different parameters.
This is due to the influx of goods from China and Europe during the years of capitalization of our society. The imported columns were not adapted to the design parameters of the gas supply to our buildings. Therefore, their use may cause some danger to our lives.
The Gas Services Inspectorate systematically checks gas columns for their compliance with the development and registration project.
If a situation is identified that unauthorized replacement of a geyser performed contrary to gas consumption standards, which causes damage to the gas structure, will have to answer in a judicial administrative order.
When changing the installation location of the column, there may be reasons for the gas contamination of the room, leading to tragic consequences.
Administrative procedure imposes a fine for illegal use of an unregistered gas appliance.
The size of fines can reach very unpleasant values.
Avoid misunderstandings and fines. helpful information.
When planning replacement of a faulty geyser, you should adhere to the following sequence and price category:
1.Call a gas officer for survey gas column. When examining the column and its malfunction, the gas supply valve to the column is sealed. Fill in the data for the preparation of the Act.
2.Get in the mountains gas Column repair failure certificate. The Act must have the signatures of the chiefs of the Zheka and the mountains of gas, a seal. The fee for drawing up the Act is $ 9.
3.Apply to the technical department of gas mountains with a request to replace the column with the annex of the Failure Act with a column.
• The statement reflect that exhaust ventilation from the premises with forced switching on is not used. This is caused by the likely occurrence of the “back draft” effect in the smoke channel of the building.
• Attach to the application The act of serviceability of smoke and ventilation ducts premises. Channel checking is done once every six months. The fee for the Act is $ 25- $ 37, plus urgency.
4. After obtaining a visa on the application, pay, coordinate with the services the working hours and what materials to prepare.
The cost of a geyser from $ 100 and up. Get recommendations on brands of certified gas water heaters, compliance of their parameters for gas and water pressure. Agree Compliance gas boiler performance design your premises or plan a gas meter.
The work on removing the old geyser, installing a new one, connecting to a water pipe, installing a chimney - with the cost of materials, is estimated at 50 - 63 $.
It must be borne in mind that all materials used during the installation of the gas column have certificates use for such work.
The final stage of installation of the gas column is to obtain Act of completion. The fee for the Act is included in the cost of installing the column.
5.After completion of the work, he will turn to gorgaz to receive Gas start act.
The gas service officer checks the correct installation, tightness of all threaded connections, turns on the gas, instructs. The fee for issuing the Gas Start Act is $ 10.
Pay special attention to the presence in the lower part of the smoke channel in the wall - “ sages" It is designed to remove the crumbling channel cover, runoff, and precipitation. Sazhetruska has a tight door and is constantly closed. Its turnkey installation costs $ 15.
6. To start and set up the geyser, it will contact the installation unit. Receive Commissioning Act. The cost of the Commissioning Act is $ 13.
It may be required during regular inspections by gas service employees.
The total cost of work and materials may be (in $):
Disinfection Act - 9
The act of serviceability flue and ventilation. channels -25 -37
Gas contamination detector - 25 - 50
Work on the replacement of the gas column - 50 -63
Gas Start Act - 10
Installation of “Sazhetruski” - 15
Commissioning Act - 13
Total: $ 197
Geyser - from 100
Total: $ 297
Analyzing the results, we come to the conclusion - the replacement of a gas column legally, cost 2 times more than the column itself. When purchasing a gas column, it is appropriate to consider models more expensive and reliable, since the cost of installing them does not increase.
It is advisable to consider the price category of $ 225.
Useful information in this article. will help you legally replace the gas column. Your time and money budget will not be affected.
Geysers are an invariable attribute of Soviet cuisines in many cities. If there is no centralized hot water supply, they are an opportunity to quickly warm a large amount of water. Today they are basically replaced gas boilersHowever, the installation requirements, the necessary documents and the inspection authorities remained the same.
The gas water heater is still a frequent guest in our apartments.
Column or instantaneous water heater - a device that, by burning gas, heats the flowing water. Gas can both be delivered through pipes, and there can be liquefied from a cylinder. But in practice, urban apartments use only natural gas. For many old houses, a column is the only way to heat water, because the wiring power is not designed for use.
It can not always be seen, but a gas column is needed
Flowing water heaters often stand in Khrushchev and Stalin. Old models are lit by matches, and heating depends on the flow of water. Now they have been replaced by options with electronic control, automatic ignition and electronic temperature control.
In private houses and large country apartments, gas boilers are used instead of columns. Their difference is that the boiler has 2 separate circuits - heating and water heating. The column heats only running water.
Advantages
disadvantages
Strict requirements for installation and further operation, due to the potential danger of the device.
Technical requirements
A column or boiler is a device with increased danger, so the installation is strictly regulated. If the requirements are not met, the gas in the apartment is turned off until the installation site meets all the recommendations of the gas industry. All manipulations with gas appliances must be carried out by certified organizations. A package of documents is also important, without it gas will not be connected.
Technical requirements:
Exploitation
The geyser in the kitchen is convenient
The first start-up of gas and water is performed only by GORGAZ employees. After installation, the gas devices are put on a balance, they and the air exhaust system are checked once a year. Correspondence of columns and boilers that can be serviced by gas workers is checked at the same time. Some gas companies do not service gas models, such need to be checked annually, inviting specialists from the service center.
Models with a closed combustion chamber do not require a chimney, but the ventilation of the room must be in good condition.
Installation algorithm
Installation of a geyser should be carried out by specialists
The documentation is regulated by the law on gas supply to the population. The list differs according to whether you only change the model, device and location, or install equipment for the first time.
Model is changing
The column becomes obsolete over time and can be upgraded by replacing it with a more modern one.
- Buy certified gas heaterwhich is allowed to install.
- Take in the Housing Office certified copies of gas and water supply schemes with a clearly marked installation location.
- Then take application for replacement, provided that the installation site in the gas service is preserved, the same statement on the repair of water and gas pipelines on the site.
- The gas service will do the work, it will also give the Act on putting the equipment into operation, compliance with the requirements.
Change device and installation location
How to install a gas water heater video master class:
- You will need change the gas, water, air intake.
- Come to the fire department to take the Chimney Status Act.
- Order a transfer project at GORGAZ or a private certified organization, get it.
- For tenement house need redevelopment permission from the city administration.
- You should have an act, a project, a permit, a boiler certificate or columns, a document on the ownership of the apartment in your hands. With these documents and a statement, contact the gas service again.
- Specialists will install and connect the equipment, conduct the first start-up. Then they will seal the meter, issue the Commissioning Act.
- In the end, you should have acts on your hands that confirm from the fire inspection, technical supervision, and commissioning. Information about the transfer is additionally submitted to the BTI.
First install
To install a gas water heater, you need to collect quite a lot of documents
If gas is not supplied to the house, the construction of a gas supply line will be required. This is an expensive process, and many owners of private homes prefer solid fuel boilers. For multi-apartment buildings, gas is supplied by the developer, the Housing Office or is carried out by the owners in a fold.
In a small kitchen, placing a column is a bit problematic, since any centimeter counts
- Getting documentation includes consent to gas supply from distributors and conveyors, calculation of consumption, receipt of technical conditions, permission for land allocation for the gas pipeline.
- Design consists of the conclusion of a project contract, the collection and examination of documentation, approval by the authorities listed in the previous paragraph.
- Building consists in construction and installation works and commissioning.
- The end is contract about gas supply in GORGAZ or OBLGAZ.
List of documents
The list below is approximate and as complete as possible, but it depends on the region. In addition, if the connection is not the first time, some documents may already be in the appropriate services or be in the hands of the owner of the apartment building / in the housing office. So you will need:
How to build a geyser in an apartment:
Types of columns and boilers for apartments
If we talk about gas heaters, they can be flow and storage. But in Russia, gas boilers are not widely used, because they are less convenient, more expensive and take up a lot of space. They should only be installed if the gas supply is too weak. Basically put flowing gas heaters.
It’s not easy to build a gas column: you need to comply with safety requirements and you want to fit beautifully into the interior
Modern models may have a closed or open combustion chamber. Open ones are a bit safer and require less documents during installation. They are needed if there is no chimney in the house. The second ones are suitable if replacing the old heater with a new one, the chimney and gas supply have already been made and checked.
Suppliers offer 3 types of capacity. 17-20 kW are needed for a one-room apartment with 1 occupant. If a person takes a shower, there isn’t enough power to wash the dishes. Devices with a power of 20-26 kW are indispensable for apartments. They provide 15 liters of water per minute at a temperature of 40 degrees. The power of an average heater is enough for a family of 4 people and an apartment with 1 shower and 2 sinks. Power 26-28 kW is suitable for two-level apartments or houses.
When heaters are not allowed to install
The geyser in the kitchen can look quite harmonious
- If you live in a one-bedroom bedroom. The kitchen should be a separate room.
- If you want to install a gas heater in a living room, bathroom or on a loggia / balcony.
- If the door to the kitchen is deaf, there is no ventilation gap.
- If the length of the water hoses and especially the gas is more than 2.5 m.
- If gas stove or another source of open flame almost adjacent to the boiler.
- If you plan to hang the heater on a wall adjacent to the living room.
How to create autonomous heating in the kitchen, video:
Boilers and columns allow you not to depend on the vagaries of suppliers of warm water, provide a comfortable temperature of water at any time of the year. Although the requirements for their installation may seem too stringent, this is done for the safety of residents. It is better to immediately install the equipment correctly than to pay later for its transfer and reconnection of gas.
