Any node role. Therefore, the correspondence of the parts of the structure must be carried out correctly. The heating system includes batteries, a connection system, thermostats, fasteners, an expansion tank, manifolds, a boiler air supply, pipes, pressure increasing pumps. On the open resource tab, we will try to find and select the necessary parts of the system for the cottage. The heating design of the apartment has some elements.
The use of boilers for heating and heating water is becoming increasingly popular today. The use of the cheapest type of fuel - gas and ease of operation guarantee this equipment demand at any time of the year.
Main types
In addition to single-circuit and double-circuit boilers, columns. a distinction is also made between models with natural draft and with a closed combustion chamber. The first type, during operation, uses a chimney, which must be present in the room. In products of the second type, combustion products are removed using a fan, for which common ventilation systems of apartment and private houses can be used. Therefore, such boilers are widespread not only in private DOSs, but in multi-storey buildings. The water-indicating boiler of the column maintains the optimal water level. Also in our market, models are being actively promoted not only with the flow-through principle of heating water, but also with a built-in battery. Condensing boilers have a high percentage of efficiency and, at the same time, guarantee economical operation even at high power levels.
How the draft sensor works in a gas boiler
Traction sensors can have different structures. It depends on what kind of boiler they are installed in.
There are currently two types of gas boilers. The first is a natural draft boiler, the second is a forced draft boiler.
Types of sensors in boilers of different types:
- If you have a natural draft boiler, then you may have noticed that the combustion chamber there is open. The draft in such devices is equipped with the correct dimensions of the chimney. Draft sensors in boilers with an open combustion chamber are made on the basis of a biometallic element. This device is a metal plate to which a contact is attached. It is installed in the gas path of the boiler and responds to temperature changes. With good draft, the temperature in the boiler remains low enough and the plate does not react in any way. If the draft becomes too low, the temperature inside the boiler will rise and the metal of the sensor will begin to expand. Having reached a certain temperature, the contact will fall behind and the gas valve will close. When the cause of the breakdown has been eliminated, the gas valve will return to its normal position.
- Those with forced draft boilers should have noticed that the combustion chamber in them is of a closed type. The draft in such boilers is created due to the operation of the fan. A thrust sensor in the form of a pneumatic relay is installed in such devices. He monitors both the operation of the fan and the speed of the combustion products. Such a sensor is made in the form of a membrane that sags under the influence of flue gases that arise during normal draft. If the flow becomes too weak, the diaphragm stops bending, the contacts open and the gas valve closes.
Draft sensors ensure normal boiler operation. In natural combustion boilers, with insufficient draft, symptoms of reverse draft may be observed. With such a problem, the combustion products do not go outside through the chimney, but return back to the apartment.
There are a number of reasons why a draft sensor may be triggered. By removing them, you will ensure normal operation of the boiler.
What can trigger the traction sensor:
- Due to a clogged chimney;
- In case of incorrect calculation of the dimensions of the chimney or its incorrect installation.
- If the gas boiler itself was installed incorrectly;
- When a fan has been installed in the forced draft boiler.
When the sensor is triggered, it is urgent to find and eliminate the cause of the breakdown. However, do not try to forcibly close the contacts, this can not only lead to the failure of the device, but also dangerous to your life.
The gas sensor protects the boiler from damage. For a better analysis, you can purchase an air gas analyzer, it will immediately report the problem, which will allow you to quickly fix it.
Overheating of the boiler threatens the entry of combustion products into the room. What can have a negative impact on the health of you and your loved ones.
Column boiler installation
The gas boiler with the help of the burner heats the water, which is supplied by the pump to the heating circuit. The main characteristics of such a product are the power and volume of water required for the functioning of the system. Accordingly, the larger the area that needs to be heated, the more the power of the corresponding equipment should be. The main advantage of modern products is reliability. Safety systems, including ionization control, allow boilers to be used with maximum benefit and with minimal risk of malfunctions and possible damage.
The installation of the column boiler must be coordinated with the gas service. The wall-mounted boiler is attached to the wall with large self-tapping screws. The wiring is mounted at the bottom. The cold water pipe must be fitted with thermal insulation to avoid condensation. To protect against limescale, it is best to use a magnetic transducer, which is placed at the input of the column. The long service life of such a device guarantees comfort in using the boiler. To connect the gas, you need to purchase a special hose, and to relieve pressure in the system - a safety valve. The final step is connecting the boiler to the mains.
The gas column does not ignite
When a technical device refuses to ignite, there may be several reasons.
Broken igniter. When the igniter is defective, it cannot burn, in which case it is required to contact the gas service. A qualified technician will replace the defective element, it is not recommended to replace it yourself - this is a real danger.
In the units of the latest models, the presence of electronic ignition is provided, which means that if there is no ignition, the gas is cut off by the valve, and the supply of blue fuel is stopped.
The instructions for repairing gas water heaters describe what to do, sometimes it is enough just to replace the battery. When there are no recommendations in the instructions, the only way out is to contact the repair service.
If there is no ventilation draft, the gas water heater will never ignite, check the draft level with a paper strip - just bring the paper to the ventilation grill. We noticed that the position of the sheet does not change - there are indeed problems with traction. In this case, repairing the gas water heater with your own hands comes down to cleaning the ventilation wells.
A metal brush at the end of a long flexible wire will help you to do this yourself, but you should not expect approval of such actions from utility workers.
If the diaphragm is worn out in the mechanism, then the burner does not work, this element deforms quickly, regardless of the cost of the equipment - for a maximum of 5 to 8 years.
To make sure that the membrane is faulty, turn on the maximum water pressure, the home master can replace the part himself.
Modern market of manufacturers
The most popular are the products of such manufacturers as:
Their cost varies depending on the volume, configuration and brand awareness. For example, a novelty - a Baxi column boiler with a digital control panel, an updated traction control system and a power of 14 kW can be purchased for $ 500. The models are characterized by increased power and, therefore, their price is approaching the $ 1000 mark. A wide variety of models allows you to make the best choice.
A gas boiler costs 20 thousand rubles - while it is not a fact that a circulation pump will be installed in it, so add a couple more thousand more. Gas water heater - 4 thousand. The temptation to save 15 thousand was very great for me, because, as I said earlier, a rogue, and I decided to use a gas water heater instead of a heating boiler.
My fears - the column will not withstand the load, the chimney will burn out, the column will overheat, the gas hose will burn out because of this - none of this happened. Everything works, I'm happy to the ass that everything worked out. The problem got out in another place - water began to run into the house, which condensed on the walls of the chimney. I hadn’t come across chimneys before, so it was an unpleasant discovery for me. They say that it is necessary to insulate the chimney pipe, but I just stuck the corrugation inside the chimney and now water drips from the chimney onto the street.
What is on my system. Expansion tank for 10 liters - 700 rubles. Underfloor heating pipes 16 mm polyethylene - 300 meters - 25 rubles. per meter. Batteries - 24 sections - 300 rubles. per section .. Pipes of batteries - 20 mm polypropylene 50 meters (a neighbor gave). Two pairs of collectors, 650 + 250 rubles each = 1800 rubles. All sorts of accessories such as bolts, nuts, valves, adapters, fittings, etc. - countless numbers, the feeling that most of the money went there. Three gas cylinders - 500 rubles each. Gas reducer with oxygen hose - 300 rubles. And you also need to install cylinders on the street - while it's at home. Fearfully. A neighbor passed gas from a cylinder through a polypropylene pipe - I will also do it. I forgot to count the chimney pipe - corrugation 200 rubles. for 3 meters. Galvanized pipes 8 pieces, 120 rubles. per piece (1 meter). Mounting bolts - 200 rubles. Fungus on the pipe from the rain - 240 rubles.
And here's what happened. I had an electric boiler. But he got me, because last winter, heating costs 10 thousand rubles a month. According to my calculations, about 3 thousand rubles will be spent on gas. per month
The system works like this. There are two circulation pumps (without a hydraulic arrow). One in front of the gas water heater, the second after the batteries in front of the underfloor heating. They are turned on by a thermostat, which I took out of the electric boiler and tied it directly to the manifold with electrical tape. The circulation pumps are turned on, they draw water - the water flow turns on the gas water heater. After five to ten minutes, the thermostat turns off the pumps and the gas in the column goes out. Everything works like a clock.
Disadvantage - a lot of heat is lost through the chimney. Therefore, next year I will try to get money for a normal gas boiler with a coaxial chimney and a closed combustion chamber. But for now, for the time being, you can use a water heater, its power (20 kcal) is quite enough for a 50-60 meter house.
This sheet is written for those who doubt whether it is possible. You can, I did it. Most of all I was afraid that the water pressure generated by the circus pump would not be enough to turn on the water heater. Enough. In those characteristics of the column it is said that the minimum water pressure is 0.02 MPa.
Seek and find.
P.S. In addition to the indicated 25 thousand, another 5 centimeter concrete layer is needed, in which 300 meters of pipes are recessed. (3 cubes, 4 thousand rubles each). Reinforcement mesh that holds these pipes.Extruded polystyrene foam 5 cm thick (250 rubles per meter, 65 meters = 17 thousand with delivery). Lighthouses - 10 pcs for 200 rubles. (reused). And for something else you need to buy food during work. Total in the region of 60 thousand only net costs. It is clear that I will not pull a normal boiler right away, so I have to be perverted with a gas water heater.
And if you remember, my first step was a conversation with a heating engineer, who asked for 40 thousand for installing a chimney and five batteries. For work on a warm floor, they would have charged me 50 thousand more. Thus, with my hard work and indispensable health, I saved it, which means I earned 90 thousand rubles. Time was spent on everything about everything without straining about two months.
Boilers are subdivided according to the type of installation: wall-mounted and floor-standing. The first type is used for rooms of small dimensions and therefore the appearance is very compact and with less power.
The second type is installed both in a separate room and next to the heating system. Floor standing boilers differ in capacity, mainly models are produced, more than 30 kW. The disadvantage of the second option is massiveness.

Power, type of ignition and burner
Piezo ignition
The most important parameter of the device is power.
It is she who determines the minimum energy costs and the future comfort of housing. You can calculate it yourself, given that with an area of 10 sq. m and a ceiling height of 3 meters, one kilowatt of power will be required.
There are several ignition options: from a hydraulic turbine, electric and piezo ignition.
The first type (turbine generator) is widely used in expensive modifications. As soon as the hot water tap opens, the burner automatically ignites. The high cost is the only drawback of the device.
Electric ignition also occurs when the hot water tap is opened. For the device to function, it must be provided with a power supply unit (batteries), which must be replaced periodically.
In the piezo ignition device there is an element from which a spark comes, when the gas opens, the automation is triggered and thereby the igniter is connected.
The task of the burner is to combine gas and air in certain proportions, resulting in complete combustion of gas, which increases the efficiency of the equipment.
By the method of transmission, the following options can be distinguished:
atmospheric, ventilatory and diffusion-kinetic. Also, burners are divided into several types of fire control, namely: two-stage, simulated, single-stage. The most commonly used modulation option.
The gas column dies out
When a household heater first turns on, but soon fades out, the reason often lies in a malfunction of the bimetallic temperature sensor, which is required to protect the device from overheating. If the temperature sensor is broken, the device may not turn on, and then the development scenarios may be as follows:
The gas burner ignites, the equipment turns on and works properly for some time, but it dies out quickly, after which it will no longer be possible to ignite the heater. It will take 20 or 30 minutes, and only then can the equipment be turned on again, but then the same thing happens.
If the sensor is too sensitive, then we are talking about a factory defect. It is better to call a master and make warranty repairs, rather than torment yourself trying to get the device to work.

The equipment turns off in a chaotic manner, sometimes it fails to turn on. The insulation on the conductor has worn out, as a result, a short circuit to the body has occurred, then the safety valve is triggered, the column ceases to function normally. And in this case, the service center employees will help you.
