Connecting the cold water to the gas water heater

How to connect a gas water heater in the apartment, installation in a private home

Independent connection of the gas boiler is not an easy thing. Without special skills you can not do without. So if you have no idea how the construction is arranged, it is better to turn to a specialist. Let’s consider the moments that home masters need to know: what documents will be required, what tools should be prepared for the proper installation of the device with their own hands.

How to install a gas boiler in a private home: installation rules

Residents of the private sector appreciate the autonomy. The main thing. to ensure a comfortable life, which is impossible without hot water. Installation of a gas water heater will solve problems with DHW (hot water). But how to solve the problem with its connection? What you need to do the work with your own hands? Let’s understand what permits you need to get and what documents to draw up in order to legalize the installation of appliances.

Norms and rules of installation

Technically, the installation of the speaker with their own hands is not difficult. However, not everyone is able to act in strict compliance with safety regulations. To install the equipment can be done by a person with the appropriate skills, but to connect to the main line. only a specialist of the company with a license.

Prior to action, it is required to collect the necessary documents and obtain permits. What registration scheme to choose in order to legalize the work? It depends on a number of reasons:

  • This is the first time you are installing equipment that will replace the central water supply (provided that the room has gas).
  • You want to replace an old or broken unit.
  • You comply with the requirements of the service to move the device from the bathroom, toilet or other place not intended for this purpose to another room.

It is important to take seriously the choice of technology. It is important not only the design and capacity of the product, but also the type of combustion chamber. If your house is laid chimney (not to be confused with the ventilation), you can buy an open-type model. They are presented in a wide range. But if there is no chimney, then the model of the closed type is suitable: the combustion products are forcibly discharged in it, through a channel in the wall.

Let us repeat: be careful. Incorrect choice will lead to the need to replace the equipment and unnecessary costs.

Now about the documents. To install a speaker in the kitchen, you need to get a permit, register it. But first you need to collect a package of documents. It is important to know that in some situations, the speaker installation is not possible.

Location of the water heater is not provided

Surprisingly, but in apartments, where the stove is allowed, it may be forbidden to place a flow heater. This is possible in buildings with a high number of stories (more than 11 floors), as well as when redesigning the premises. We are talking about cases where the apartment is remodeled as a “studio” or combined kitchen and living room. for the installation of gas appliances is not allowed. This also applies to apartments without a kitchen or communal living quarters.

Gas equipment is not allowed to be placed in residential areas.

If you have a studio apartment. this option also falls under the ban. In this case the kitchen is combined with another room, i.e. living space. Common kitchens, such as in dormitories, also fall into the prohibited category. Before deciding to purchase a water heater, carefully examine the documents on the apartment. They contain the necessary data about the parameters of the room.

Gas Water Heater Installation

  • Application to the gas service.
  • Proof of ownership.
  • The project of gas and water mains, chimney.
  • A floor plan from the Bureau of Technical Inventory.

After the documents are collected and the registration permit is obtained, specialists will come out to you and make the connection as required by law.

How to change the equipment

Here everything is a little simpler. Since the documentation was collected during the initial installation, you need to go to the housing and utilities department, take copies of schemes, a plan of piping, chimney. Then write two statements:

If you want to install the equipment at the new location, you will need to get a project for the conversion. This is due to the fact that the supply line will undergo changes. In fact, you need to put together the same package as you did with the initial installation.

SNIP 42-01-2002. standards for the design and construction of gas distribution systems. They specify the requirements for the equipment.

How to install and connect a gas water heater yourself?

A gas water heater is something that is necessary for the common man in domestic use. Most men, in order to save money, begin to do the installation of the equipment themselves.

The gas column in the house. pros and cons

Providing hot water is carried out by different equipment, differing in principle of operation and used fuel. Column. a flow-through water heater, which uses as the main source of heat, the energy derived from the combustion of gas. Water enters the coil located above the burner, heats and is sent to the DHW system of the building.

Modern gas water heaters are fully automated, turned on by opening a tap of hot water and are highly economical.

The alternative to flow-through gas water heaters. storage boilers, which are somewhat different by principle. The gas burner does not heat the coil as in the column, and heats the air that is sent to the flame tube (located in the storage tank) and in contact with the liquid. Otherwise, the gas heater works like an electric boiler, maintaining a constant heating temperature.

Installation of a gas water heater in a private country house has not only positive aspects. The disadvantages are:

  • costs associated with registration and connection;
  • potential risks associated with possible gas leaks;
  • High requirements for water heater installation.

In practice, the column is placed simultaneously with the installation of a gas boiler, or connected to the house, where the gas is already installed and heating equipment. Making a project solely for the water heater is expensive and economically impractical.

Is it possible to use a mixer with a gas water heater?

The gas-flowing water heater has one distinctive feature. The temperature of hot water should be regulated by the change in gas combustion, and not with the help of their cold pipeline.

In fact, even if a water heater mixer is installed, it will not be fully usable. In addition, after the installation of the faucet, there is a possibility of water hammer, with improper use increases the likelihood of rapid failure of the speaker.

During Soviet times, the question of choosing a hose for the gas equipment in general did not stand before the home craftsmen, as both columns and stoves, and other appliances connected only standard steel pipes. This solution was reliable, but it was impossible to install the equipment without an angle grinder and welder, and installed equipment could not be moved.

With the advent and wide spread in the Russian market of materials that combine strength and flexibility, the number of options has increased significantly. It is important to remember that the hose used for gas supply should:

  • Be strong enough to withstand possible mechanical loads and gas pressure;
  • Have enough flexibility;
  • be resistant to wear and corrosion;
  • not to react chemically with the gas in it;
  • be absolutely airtight (when properly installed) to prevent leaks.

Products that meet these requirements are necessarily marked in yellow. In this case, the whole hose can be yellow, as well as the tags on it, and other design elements (fibers in the braid). The usual white hoses are only intended as water hoses, so they must not be used for gas supply under any circumstances.

Nowadays, the 3 main types of hoses for gas supply are the most common, namely:

Consider the advantages and disadvantages of each option in more detail.

Hoses made of rubber or cloth

In such products, textile thread is used as a reinforcing element. Due to the fact that metal in such products is used only for fittings, they cost markedly less than other options of gas hoses. Another important advantage of these options is the absence of metal along the length of the hose, which makes it an excellent dielectric and reduces the risk of explosion in accidents and leaks.

The main disadvantage of this option. significantly lower durability than that of more expensive products. Small cracks appear rather quickly in places where such a hose is bent. Therefore, such a product sometimes has to be replaced after two years of operation.

Metallized models

Due to the protective shell of metal fibers such hose is much stronger than a rubber or fabric hose. Nevertheless, this option has also a number of important disadvantages:

  • this hose has a through conductivity, so the use of dielectric gaskets is mandatory for its installation;
  • The braid does not allow you to visually detect damage to the polymer “stuffing.

Bellows sleeves

These hoses represent a basis of steel sections in a polymer or metal braid. All of them are highly durable and reliable. Options with a polymer braid additionally possess dielectric properties, and products with a steel braid are the most reliable of available options. The main disadvantage of such hoses. their high price.

Peculiarities of connecting a gas water heater

In order to always have comfortable living conditions in the house, it is necessary to take care of hot water supply at any time of the year at the right temperature. Therefore, the owners of apartments and private houses prefer to install special equipment that will provide this need.

One of the most popular products for heating water is a column. This is due not only to the efficiency of its work, but also the budget consumption of fuel. Thus, the installation of a gas water heater will cost less than a boiler.

How Do Gas Water Heaters Work? | Repair and Replace

To connect the gas water heater is simple enough, if you know all the nuances and requirements for these units. That is why, below we will consider all the issues and questions that everyone will face when buying and installing equipment.

Installation of a gas water heater

After the appropriate documentation is prepared, it is necessary to purchase all the necessary materials and accessories that are needed to install the column.

Basic accessories include:

  • chimney pipe with a diameter that corresponds to the outlet spigot of the device;
  • the required number of water and gas pipes with fittings according to the project;
  • appropriate water and gas filters, as well as fittings on the pipes;
  • Elements for fixing the gas water heater to the wall
  • galvanized steel for separating the wall and the gas column.

Tip: The entire list of necessary accessories must be included in the appropriate certification to the developed project.

If all the materials have already been purchased, then you can proceed directly to the process of installation. It is necessary to observe all the distances for optimal placement of the device on the wall. All this is specified in the instructions for the installation of the water heater.
