Repair of gas columns at home: step by step instructions to solve the most common problems

Gas hot water supply column is a fairly common devices in private homes and some apartments. Since this equipment associated with gasThen to his operation and maintenance should be approached with great responsibility. Before exercising independent repair geysers at home, should be made the correct setting, and when equipment failure - to diagnose. On the causes of major breakdowns, and configuration specifics of gas columns, and will be discussed in this article.

Apparatus gas column and working principle

The operating principle of the gas column as follows. In the enabled column is lit igniter (the pilot burner) igniting main burner opens after the hot water tap and hot water pressure in the system falls.

The basic elements of the gas column are:

1. The casing of the outer housing - protects the internal components from external impact.
2. Diverter - creates necessary for the functioning of the level of thrust.
3. Heat exchanger.
4. Gas-burner.
5. Gas supply assembly.
6. water spout.
7. Control unit.

How to enable the gas column and adjust the basic parameters: temperature, water pressure and the flow of gas

Depending on the model of management and control system is equipped with an automatic igniter pezorozzhigom or under electronic control. Column with hand primer, which is required for a match, obsolete and currently are not used.

How to light a gas column of different types?

The electronic controller. When you open the tap in the heating system water pressure falls. The pressure sensor sends a signal to the microchip system activates the sparking and opening a gas supply valve. Under the influence of a spark igniter ignites itself and ignites the main burner which heats the water in the heat exchanger. After closing of the tap pressure level is restored, and the microchip shuts off gas.

Important! Gas water heaters with electronic control systems need to be connected to the power supply and / or installation of more power the battery.

Pezorozzhigom. The column is equipped with a device that converts mechanical motion to electric discharge, enabling the spark. For initial inclusion on the instrument panel should press the button and turn the gas valve.

Adjust the main operating parameters

Temperature. Controlled heating water temperature gas column - a fairly simple procedure. In addition, the device is set to Automatic average and most users do without any additional configuration. But it is necessary to perform, so you do not raise questions: "Why are gas water heater heats the water is bad?"

It is necessary to set the temperature of water directly on the device so that during operation not to use a mixer. When the pressure in the mixer the cold water system falls and the column can turn off all of the lack of pressure. However cranes in the kitchen (in the wash), in the bathroom (washbasin) And in heartUsually have different diameters and different intensity of water consumption. If the set column for maximum heating temperature of 25 ° C, then the kitchen it is 22 ° C, in the sink bath 21 ° C, and in the shower of 20 ° C. For many, this water is too cool, and put the maximum temperature is not recommended, as the heat may quickly burn itself out under boundary loads.

There is an original way out of this situation. Instead of each time before showering to translate the temperature to the maximum, you can purchase a shower head with a multi-stage switch. Thus, by placing the switch on the maximum flow of water can be obtained a low temperature and setting the smaller jets mode (reducing water consumption) can be prepared above the temperature to 5 ° C.

Gas. Install the batteries or connect Water heater To household power outlet. Open the valve and gas regulating switch set gas supply at the minimum value. Conversely the water supply valve set to the maximum value. The hot water system opening only one valve for the supply of medium intensity. We expect for a while, until the water temperature stops rising. Increment the gas supply to the moment when the temperature difference between the incoming cold and hot water used will not be 20 ° -25 ° C. Subsequently the whole temperature control is carried out exclusively through the water supply valve.

Important! It is advisable not to raise the temperature difference more than 50 ° C. This will significantly increase the lifetime of the equipment.

How to check the thrust of the gas column?

The sensor rod is one of the key security system of detectors. It is responsible for the timely removal of the combustion products. Depending on the combustion chamber-type thrust sensors are:

thermal relay based bimetallic plate - mounted in a gas water heater with an open combustion chamber. Location - diverter rods. The principle of operation is to control combustion temperature (120 ° C... 140 ° C) is discharged through the chimney. If the outflow of gases is blocked, respectively, the temperature rises in the region of the thrust diverter and the sensor shuts off the gas.

Diaphragm pneumatic relay - set in the parapet of gas columns with coaxial extractor. Such a hood is characterized Forced evacuation of combustion products. When the fan of the flue gas stream leaves the channel successfully coaxial drawing, the pneumatic relay membrane is concave and the contacts are closed. If the fan does not work any clogged channel diaphragm is unbent and the contacts are opened by cutting off the gas supply.

two thrust test method for devices with open combustion chamber available to the average user:

mirror method. A small mirror set in place the diverter rod, which is located near the sensor. After a few minutes of operation at full power column stops. With good traction mirror must be clean - no steamy.

match method. Burning match tray to the window on the front panel.

• if the flame is deflected forward, in the direction chimney - draft is;
• if there is a fixed - no traction;
• if the flame has deviated toward the room - there is an effect reverse thrust, it is necessary to immediately switch off the column.

What tools are needed to carry out the repairs yourself geysers at home?

• Screwdriver or set bits, including flat and cross;
• Set carob keys;
• tester;
• soldering iron.

The benefits of soldering It is questionable, because the repair of modern technology is made on the basis of the replacement of the failed unit. A contacts the external interface controller - either the bolt or the pin connections.

Perhaps the repair will need different seals, gaskets and rings. Typically, the diameter of the pipe connections for water connection of most speakers are unified. However, gaskets and fasteners for heat exchangers, membrane and diaphragm valves, filters, rod seal, etc. may be different even for different models of the same manufacturer. Therefore, the most advisable to purchase a complete kit for the specific model of the gas column.

Typical faults gas column: causes and ways to repair

Despite the apparent complexity, diagnose faults, most geysers, as well as carry out in-line maintenance and minor repairs can be any technically literate home master. To clean the blockage and replace the gaskets do not need to have special education. Besides sorting out the types of damage, you will be able to assess whether the costs of work caused by the wizard is adequate.

Repair gas heat exchanger column in the formation of limescale

The reason for the formation of scale in the heat exchanger is hard water. The presence of salt deposits on the inner walls significantly decreases the heating efficiency and increases gas flow. Therefore, if it is known that the water in your area has a lot of salt, it must be cleaned regularly. This is done as follows:

1. Overlaps supplying cold tap water.
2. Opens the next hot tap and merge the remaining water from the hot water system.
3. The heat exchanger is best to remove all. His radiator needs to be cleaned of soot. If the gas quality is low, but the experience may not be less of a problem than scum.
4. The large basin with a brush the outer part of the heat exchanger is cleaned of soot.
5. The heat exchanger is filled with cleaning fluid. Best of all, if it's a special factory prepared solution. When it is selected, make sure that the composition of the material suitable heat exchanger: copper, stainless steel, bimetal, cast iron.

You can also use self-prepared cleaning solution:

• 500 ml of distilled water;
• 100 ml of a 9% vinegar;
• 120 g citric acid.

The cleaning composition should be in the heat exchanger at least a day. After cleaning column is collected, all gaskets and sealing at the joints are changed to new ones.

Gas water heater does not come on or goes out immediately

If the column until the problem was functioning normally, the fault causes can be multiple:

Gas water heater goes out after a period of operation

If the gas boiler is turned on, and then went out, the reasons may be as follows:

Gas water heater does not heat water

If the gas boiler heats the water is bad, but the head is good, two reasons may be:

1. Insufficient capacity column. Typically, the marking pattern present figures, they represent the volume of heated water into minute: 6, 10, 12, 16, etc. If hot water is used only for the kitchen, it is enough to power 6 l / min. But if you plan to connect two points of consumption, for example, a kitchen and a shower, it is necessary to acquire the gas column capacity of at least 12 l / min.
2. Improper adjustment primary gas supply. If set to deliver gas to the minimum value, even with a high power speaker can not provide multiple points of hot water consumption.

Gentle pressure of hot water from geyser

If the hot water pressure decrease observed after the repair work with total shutdown Water, the most likely cause is the water shock, tore portion with scum heat exchanger. Insoluble particles of this scale littered mixerThat needs to be cleaned.

What if the radiator flowing gas column?

1. The column is disconnected from the cold water, the remnants of the DHW water merge.
2. Extracted exchanger.
3. When manufacturing a heat exchanger material - copper, the leak can be detected by green patina.
4. If visually identify the fault location is impossible, the heat exchanger must be completely omitted in soapy water, and then blow out, preferably using a pump. At the site of injury foam appears.
5. The injury site is protected by sand paper and degreased ( "White Spirit" can be used).
6. using soldering Iron, Rosin and solder luditsya place around the aperture, whereupon it deposited a tin layer thickness of 1.5-2 mm.

It is possible to use a gas burner of a set of equipment for copper pipe heating installation.

As an alternative the heat exchanger may include a service, where they make repair of automobile radiators. Terminating holes using argon welding will be significantly more reliable.

Replacement of gaskets geyser

Leakage appears in field connection for supplying cold water and hot water withdrawal is eliminated by simple replacement gaskets. This action is so elementary that to describe it does not make sense.

However, the leakage may be due to membrane damaged water node. Her replacement is a routine maintenance, and is not included in the warranty, as membranes are consumables.

• water node disconnected from the water pipes (spanner 24) and the gas rod assembly (flat-blade screwdriver);
• perimeter bolts unscrewed, after which the cover is removed;
• changing a failed membrane and assembly is performed in reverse order;
• when installing the water knot on the place (when connected to a water supply) it is necessary to replace the old poldyuymovye pads.

During power geyser heard claps

Causes of abnormal noise can be several:

Important! The spark plug may have other names: glow plug, an ignition electrode, a spark electrode.

During operation, the gas column smell

Possible causes of odors - leakage in the connection points of the gas tube or a leak in the most column arrangements. In any case, you should immediately turn off the column and all other sources of open flame in the apartment, ventilate the area and call the gas service representatives. Independently find estrus is possible by means of soapy water.

Important! In no case can not use a lit match.

Repair at home geysers popular manufacturers

Even the popular models of geysers the most reliable manufacturers have defined typical damage.

Features Bosch Repair of gas columns

The main disadvantage characteristic for gas boilers and columns Bosch, is the high sensitivity to fuel gas quality. During prolonged operation at the gas burner is deposited a large amount of soot, which can lead to periodic shutdown. Then gas water heater is not activated when the water. Another problem is the displacement of the igniter and the periodic failure of a thermocouple sensor

Nuances repair their own hands Junkers geysers

In some models Junkers geysers too sensitive thermostat. This manifests itself in that after the ignition of the gas burner igniter may be extinguished. How to light a gas column in this case again? For prompt remedy the situation, you can simply ventilate the area. The total temperature drop and the gauge will begin to re-included. But constant repetition is recommended only for a substitution.

Repair your hands geyser Oasis

Despite the fact that the manufacturer of gas columns Oasis from Germany, they also have a number of specific weaknesses. As a rule, it is connected to electricity. Most typical is the failure of the microswitch, as well as a fault of the solenoid valve in the gas node. If the first column can be corrected by simply replacing their own, the latter requires the intervention of a specialist.

Features of repair of a gas column vector

According to the data of the online forums, a typical problem of gas columns vector is sticking a rod that activates the water valve assembly. Also, often the system power contacts are oxidized, resulting in a geyser vector is not lit even after the batteries are replaced. The way out is a thorough cleaning of the contacts, and periodic replacement of the rod gland.

findings

There are many other less common causes of failure of gas columns, but most of them are discussed in the various technical forms. As a rule, these faults can be eliminated completely by yourself.
