One solution to the issue of heated water supply - installation of flow-through water heater.This becomes the object of attention is a geyser.For gas water heaters compared to electrical are more economical due to low tariffs for energy, and compared to storage water heaters - more comfortable, because they allow to use hot water in any amount and at any time.At the same time identify the main problem arose and to repair the gas column with your hands.

A gas column
ordinary gas water heater is an iron box that resembles a kitchen cabinet.To him it summed up the two pipes - gas and water.Interior design includes a heat exchanger, the primary and the pilot burner.After you open the tap, depending on the method of ignition of the burner, the valve opens gas flowing energy to the pilot bu
On combustion gas heat is released, which is sufficient for rapid heating of water that passes through the heat exchanger - located above the burners of the spiral tube.The heated water is directed through a water pipe that comes out of the gas column to the tap (faucet in the bathroom, shower, kitchen faucet), which was open.Products of combustion gas is removed turn the chimney, which goes out from the top of the gas column.
columns by the method of ignition are electronic ignition, manual type and pezorozzhigom.Outdated manual ignition involves the use of matches: open the gas valve, which is suitable to the column tube, hold a lighted match to the igniter that lights up at once.The main burner will light up after turning the handle.
modern gas water heaters have a more comfortable, practical and safe electronic ignition, running "on full automatic."After opening the faucet is activated by water pressure system in which the charge spark produce two penlight batteries, the gas valve opens at the same time.Sparks enough to ignite the burner, then everything will be a familiar system: light up the second burner heats the water and go through the heat exchanger to the tap.The burners are turned off after closing the tap.
pezorozzhigom specific system that is based on the piezoelectric effect when the mechanical action is converted to electric discharge, in this case - a spark.For the first time including a new column on its front panel, you press the button, activating a piezoelectric element.From the resulting spark ignited igniter and then main burner.The main burner is extinguished when closing the tap, and the glow - lights on, but it is not enough heat to boil the water remaining in the heat exchanger.Next time, you just need to open the tap water, do not hit and did not burning, and will warm water.
Common Problems geyser
heater is not quite a simple device which is subject to certain rules of handling and care will serve its owner for a long time.But sooner or later, all the equipment is out of order, and geysers is no exception.Particularly affect the quality of the process water and gas, which are served by municipal services in our homes and apartments, and now, after a certain time it becomes necessary to repair a kitchen with gas stove.Therefore, it is worth considering the typical reasons, due to which the device is not functioning as required.
exchanger clogged scum
The most common fault of gas columns covered in scum clogging of the heat exchanger (radiator).The overgrowing tubes blame hard water scum.Limescale occurs when the water temperature more than 80 degrees, and 82 degrees when the process begins to take place intensively.
To prevent the formation of scale is necessary not to use too much hot water.Bathing water temperature sufficiently close to 42 degrees, for removing grease when washing dishes - approximately 45 degrees, as a means for removing fat from them and able to cope with cold water, and the washing machine in the machine - not more than 60 degrees.
Many left to work at a gas column pilot light because it is convenient, and there is no need to stir up and customize column each time.However, lack of time and hours, the temperature in the heat exchanger had risen to 90 degrees - hence the scale.So do not be lazy to disable and enable the column if necessary, and do not over automatic heater, if you observed a weak pressure, it is better to put in this case, magnifying the pump.
Well, if you was a trouble, it is necessary to repair the Chinese gas column by washing the heat exchanger.To do this, you must understand that the heat exchanger column is really packed, drawing attention to the following symptoms: low pressure at the tap warmed water when the pressure at the tap with cold water is good;column along with it does not turn;or immediately after power is turned off.Of course, maybe it is broken valve at the inlet to the gas column, but if it is OK, proceed to disassemble the column.
To wash the column, you will need: Phillips and flat-blade screwdriver, a set of open-end wrench, a set of asbestos fabric gaskets and rubber hose.In addition, you must pre-purchase at a hardware store descaler, which is sold in a plastic bottle and a dry powder.You can also use vinegar essence, because it is the most accessible.
To begin, remove the column fixture, and then - the casing.After that you need to shut off the water supply inlet and the open close to any of the column of heated water taps.Next, remove the heat exchanger from the feed tube and move it aside.After you remove the nut from the heat exchanger, the heat exchanger will start to leave the water.It must be emptied about a liter.
further put to the input of the heat exchanger tube, lift it higher up the column, insert a funnel into the hose and pour a thin stream of it into the prepared solution.Pour slowly, or begins to work, and descaler will push back.The solution in the heat exchanger should stay for a couple of hours.The substance can be warm on the burning pilot light to faster reaction took place, and it took less time.
tap substitute basin or plastic bucket and slowly open the water supply to the gas column.Look at what comes out of the hose.If there is a lot of mud, and after washing the pressure will be good, so everything worked out, if not, it will have to repeat the procedure again.But if you use descaling is not required.
Pike radiator geyser
After leak detection gas column, of course, the desire to become the first replacement of the old to the new heat exchanger.But the cost of the radiator is 1/3 of the price of a new column, so it is advisable to try to repair the unit yourself, sealed solder with a soldering iron.As the tube heat exchanger water flows, the temperature of which can not be higher than 100 degrees, and the temperature reaches 200 ° C melting point of the solder.Therefore, brazing is melted.
fistulas occur most often on the tube that runs along the outside of the radiator, since it is often made of metal poor.On the surface of the tube which runs inside the heat exchanger, typically, fistulas do not appear.If you are able to reach the place of a leak, then before soldering drain the water from the heat exchanger, as it will remove the heat, so you can not warm up to the soldering temperature required.
To do this, open the hot water faucet in the sink or sink, and unscrew the cap nut from the pipe column that provides cold water.Since the gas water heater is located on a level above the tap water will drain most of the water, but not all.To remove residues practice purge vacuum or compressor.Only then can you begin to repair the radiator gas column.
soldering itself does not cause difficulties.Fine sandpaper strip the place of fistula oxides wipe station after cleaning cloth that is moistened in solvent to remove grease and dust.Tin solder can be any, for example, PIC-61 by soldering capacity not less than 100 W at a temperature of about 180 degrees.
as rosin flux is used.If it is not, you can take aspirin.Crumble and sprinkle small tablet crumbs place tinning or sodium tablets heated surface.If the solder does not spread at tinkering, and turns out a pad, then the soldering warmed enough.In this case, another warm soldering iron, iron or hair dryer building.
When the solder is uniformly coated with a thin layer of the surface of the device, upgrade it to a thickness of 1-2 mm, and a fistula on the heat exchanger over not show.Inspect the tube radiator throughout.If you see a green spot, so more likely at this point there is a pinhole that overlooks the water, and it needs to tin solder.Otherwise, in a few months you will again have to repair the bathroom with a geyser, since there will flow.
If water leakage portion is located on the wall of the heat exchanger, which is adjacent to the bottom of the column, the radiator in place repair is impossible, and it is necessary to remove heat from the gas column.To remove the unit for soldering, it is necessary to make out almost the entire column, and disconnects the gas pipe, but it is very dangerous.
heater does not ignite
The most common reason that the water heater does not ignite - just a lack of ventilation in the pit traction.It may happen that the chimney of accumulated soot clogged or it was a foreign object.In this situation, usually triggered protective system that is located within the column, and the instrument automatically shuts gas.Check the draft in the chimney.For this Hold a lit match, and if the flame will go away - it means, the thrust is.
Another reason that the column does not light, is banal discharge the battery, but it only applies to devices with automatic ignition (from batteries or generators).Contrary to the claims of manufacturers that time, battery life is one year, will have to change them more often.
heater also can not light up due to the poor water pressure.And it's just a check -Need open cold faucet.If there is a little pressure - it is likely that the reason lies not in the column, and in a separate area or around the pipeline.If you see that the pressure of cold water is stronger than in the hot tap, it is necessary to carry out repairs of the water unit of the gas column, as reason is in the water column node (the membrane is deformed or clogged filters).
strainer could clog the inlet water unit after turning off the water and reverse its flow.To clean, simply unscrew from the water supply a cap nut, remove the mesh and clean it.
To check the status of the membrane, remove the unit from the water two union nuts, then remove the three screws that hold the water in a cone assembly for a gas unit.Disconnected from each other by half a knot, you can see such a membrane.If the gum has a deformed surface, and not flat, with deflections, it should be replaced.At the same time, you can clean the cavity of the water unit and filter screen from dirt.You can put silicone membrane, which can serve for many years.
often happens that geyser goes off immediately after ignition.The reason for this failure lies in the thermocouple, but rather is a poor contact of the thermocouple and the solenoid valve.If the thermocouple is intact, it should do the repair of automatic gas column, or rather its cleaning contacts and automation unit.In such a situation, you should adjust the flow of hot and cold water.Remember that you can not in any case be diluted with cold water hot, as this will trigger an immediate extinction of the flame.
cotton and micro explosions that accompany the process of mainstreaming, can occur: because of poor traction in the ventilation duct or well, due to the discharge of batteries that are responsible for the ignition of the column due to the clogging of a jet or other elements of the column,due to the excessive inflow of gas.When the burner, gas from the igniter should ignite promptly.But if the pilot flame will burn for some reason is not correct, the gas will accumulate, which will result in a cotton - small explosions of gas-air mixture.
In this situation, you need to look closely at how the pilot flame.The light should be blue, light resistant, flame tongue must touch the main burner.If you see a pilot light yellow-red, not sustainable, small flame, it is necessary to clean the nozzle and the pilot tube, which brings gas.
Column not properly warm water
reasons that the gas water heater after turning bad heats the water, there are several.First, the column may have a small capacity.Therefore, before purchasing equipment, always carefully review the passport unit.Also, water can be heated bad because of a simple obstruction of the unit, which acts as a sign of the changed color of the flame and the occurrence of soot in the process under the column.
If the water heater does not heat, it is necessary to adjust the gas supply to the burner.In modern gas column present crane, which allows you to adjust the water flow, that is, the amount of water that passes through the column in a minute.Therefore, if the water is heated slightly, it is recommended to reduce the capacity, and the water will have time to heat up.
In addition, the column can be fed too much hot water.But in this case does not require repair and maintenance of gas columns, because this situation is not a malfunction of the column.In the warm time of year when the water in the water is warm enough, and her little head, a problem that at first glance appear to be linked to a malfunction of the column.Have you noticed that when the pen of gas supply to the column to minimum water heating water is still very hot.
just certain models of the gas column on this operation is not calculated.The instructions for use of the equipment is usually specified minimum water pressure when the gas boiler will function normally.Resolve the issue is very simple, you just need to restrict the flow of gas, with little blocking valve on what gas is supplied, and which is mounted in front of the gas column in the gas pipe.
Sometimes connections gas heater leak may occur.The left tube is needed to supply water in the column, it is always present at the valve to shut off the water supply to the column.This tube is connected to a water-gas regulator fitting.With the regulator water enters the heat exchanger on the right.In the middle column tube is transferred to the water supply hot water and it is connected to the heat exchanger through the pipe to the left.
right column tube requires a gas supply and connected to the controller through the copper tube.It also establishes a mandatory gas valve overlap.Water connections in the column are performed by union nuts with sealing gaskets of rubber.Over time, the rubber gaskets on the temperature difference lose their elasticity and become rigid, and there is flowing water.
order to repair old water heater, replace the rubber gasket in the gas column.To do this, unscrew with a key 24 union nut, remove the pad that is already worn out, and install a new one.Sometimes a little pad, nut you spun all the way, and the water is still oozing.Then further recommended to put another seal.
