Water heaters are distinguished by energy consumption. In everyday life, only gas water heaters and electric boilers are used. If a water heater is being replaced, a device with the same energy resource as the previous one is mounted. Installation of gas columns, as well as any devices with such a power source, requires the intervention of the relevant services. Operating costs are much cheaper, since the use of electrical appliances is more expensive.
Accumulative water heaters
The household gas column of accumulative type copes with water heating in the best way. There are floor, flat and horizontal devices. Thanks to several available options, you can choose a installation that fits into the interior and dimensions of the room. In the process of designing a water heating system, it is necessary to take into account the methods of air flow. Forced traction is created when appliances are connected to a pipe that goes outside. Natural draft requires continuous air supply and connection to a common ventilation outlet.
Instantaneous water heaters
The installation of gas flow type columns is carried out in Russia most often. The average price of such units in the domestic market is 15-20 thousand rubles. Once upon a time there were minor difficulties with the operation of these devices. It was necessary to monitor the flame so as not to fade, and to regulate the gas supply manually. Modern analogues are much easier to manage and pose less danger.
Installation Rules
Each installation of such devices must be coordinated with the gas services. For the installation of speakers with an open camera, there are technical conditions that must be observed. Installing the unit yourself will be very difficult if it was not previously. You will need to bind to the main gas and water pipelines. For this reason, the installation of instantaneous water heaters is carried out in the kitchen. But at the same time, it cannot be installed above the gas stove. The main installation requirement is the presence of special hoods. Previously, such speakers were installed in the bathrooms.
Replacement
You can always change an obsolete instance to a new one. For the installation of instantaneous gas water heaters in apartments and private houses, it is necessary to observe the main positions: connection to the water supply and gas pipelines, installation of the hood. If the column has already been installed, then all of the above rules were followed earlier. It remains just to mount another new unit.
Disconnect from gas and water
To dismantle the obsolete unit, access to gas and water is blocked by valves. First, the nut of the gas hose is unscrewed using an adjustable wrench. Instead, a metal tube can be installed. After that, the hose is unscrewed from the column. If the hose is intact, you can use it again. At the same time, you should not save on buying a new one. A low-quality hose can be much more expensive. After access to water is blocked, the column can be disconnected from the water supply.
Chimney Dismantling
After the pipe connecting the unit to the chimney is removed, the water heater can be removed from the mount. Before installation, you need to make sure that the old mounts are suitable for the new device.
We hang the unit
Installation of gas columns requires compliance with certain proportions. In the room, the ceiling height should be more than 2 m. The vertical pipe in the chimney should not be less than 50 cm. When the ceiling height is 2.7 m, the pipe can be 25 cm larger.
Connection
After the column has been secured with hoses or PVC pipes, you can connect it to the plumbing system. Next, you need to check the unit for leaks. If necessary, tighten all the liner nuts. The column is connected to the gas pipeline with a high-quality new or old hose. After crimping, the entire eyeliner must be treated with soapy water in order to detect bubbles and determine the reliability of the connection.
The first installation of a geyser in a private house
If the installation has not been done before, you will need to do additional more complex work. In addition to the usual rules, one must take into account that the wall on which the unit is planned to be hung must be made of non-combustible material. The minimum water pressure in the pipes is 0.1 atmosphere.
Cooker hood
Rules for installing a gas column require the selection of a suitable place for the hood. If a chimney or fireplace is installed in the room, this ventilation space can be used. Otherwise, you can make a hole in the cover and insert an asbestos pipe about 2 m long. It is best to install it near the inner wall. In the absence of an upstream channel, a nozzle pipe for gas water heaters is used.
We fix the unit on the wall
The geyser in the apartment is installed directly under the pipe. The unit must be installed at a height inaccessible to children. At a suitable level, holes are drilled into which fasteners are inserted, and then the column is screwed to the wall. Using a flexible corrugation, the unit is connected to the chimney pipes. One end of the corrugation is attached to the previously prepared hole, and the other to the column.
Device connection
To connect to the gas, a tee crashes into the pipe. This can be done by gas welding. If a threaded connection is present, the tee can simply be screwed in. Then you need to attach the gas shield. Now you need to note the distance between the pipe and the column. At the place of passage of the eyeliner, mounts crash into the wall. With their help, the pipe will hold more reliably. For these purposes, special clips with snaps are used. The pipe connects to the column using a union nut and fitting.
Water connection
Installation of gas columns provides a similar insert of a tee into a water pipe. In the same way, holes are drilled in the wall for fasteners. The Mayevsky crane can be installed and used when adjusting the water pressure. Magnesium and salt filters are mounted next to the column.
First start
It is possible to carry out a test run after the installation of a gas column has been carried out. The price for heating with electricity is much higher, so boilers are used less often. The gas valve opens and fuel enters the column. Joints of gas pipes must be checked with a solution of water and soap. The leak will need to be fixed if bubbles are inflated somewhere.
Next, the water is launched, the Mayevsky tap opens, and all the air is discharged from the pipe. After that, the batteries that supply the display and electronic ignition are inserted into the column. To check the system for hot water, open the nearest faucet. First, the flow will be cold, then heating will turn on and the pressure will be warm. At first, the water will have a not very pleasant smell of fuel oil. The column needs to be worked for a while so that the grease from the pipes is washed.
Necessary tools and accessories
Installation and repair of columns is always carried out using fittings for metal-plastic, the water heater itself, pipe cutter, salt filter, all necessary taps, including Mayevsky’s device, wrenches, drills, PVC water pipes, a special soldering iron for pipes, gas hoses, a magnetic filter, corrugations, screws and dowels.
Who is allowed to work with gas equipment?
Independent intervention in the system is extremely undesirable. Repair of the columns should always be carried out only by an employee of the gas service with the appropriate approval. This is the only way to be sure of the normal operation of the entire system.
How to connect a gas stove?
To do this, you need a special bellows hose. Eyeliner should not pass behind the oven in a hot place. The hose must also not be tensioned so that there is no possibility of damage. For threaded connections, sealing material is often used. To check the eyeliner for a gas leak, you need to lubricate it with soap foam.
The insulating connection is carefully wound onto the thread, and then a rubber gasket is inserted into the hose. After that, you can screw the eyeliner to the gas pipeline. It is not necessary to tighten the thread strongly. The stove is put in place of the old one, the legs are adjustable in height so that the hob is even.
For the technique you need to remove the wallpaper or put a metal sheet if the wall is wooden. This will prevent possible fire during oven operation. The gas hose is connected to the stove using a lining. After that, we check all the connections with soapy foam. To learn how to connect a gas stove, it is better to consult an experienced worker of the relevant service.
Proper use of liquefied gas
If the gas stove is connected to liquefied gas, you need to make sure that special nozzles are provided on the burners. Natural gas appliances have a significantly larger hole diameter. Often during installation this feature is not taken into account, and the flame periodically goes out. Before purchasing hoses, it is necessary to take into account the features of the gas outlet device on the stove.
Device Warranties
Reliability and quality of connection can only be ensured by gas service employees. Self-assembly of columns and slabs is prohibited by law. Unqualified intervention in the operation of gas supply systems can cause an explosion, fire, harm others.
Conclusion
The installation technology of gas columns, in fact, is not a big deal. When replacing equipment with a new part of the preparatory work, you can not perform it. After dismantling the old unit, it is not necessary to re-measure the pressure in the pipes, as well as remove the gas and water lines to the connection point. If the old eyeliner is preserved, it can be used when connecting new devices. Work with gas equipment can only be trusted by qualified specialists who have the appropriate approval.
