The German company "Vissmann" has been one of the world leaders in the heating equipment market for several decades. The company gained its fame, first of all, thanks to its solid fuel and gas floor boilers. And in this segment, perhaps, they have no equal at all.
AT last years the German concern is increasingly relying on compact and economical wall Viessmann gas boilers. Reviews on this species equipment are not as common as, for example, on popular boilers stamps or .
This is understandable, because the equipment from the German manufacturer has never been budgetary, and the price of wall-mounted single-circuit and double-circuit gas boilers Wiesman did not allow buying and making them affordable for the average buyer.
Today we’ll talk in more detail, and we’ll review the wall gas appliances widespread series Viessmann Vitopend 100-W WH1d. Thanks to the instruction manual, together we will determine their significant advantages and disadvantages compared to competitors, consider the main types and specifications German boilers of this brand.
The main types and models of wall-mounted gas boilers Wisman
To date, the German concern produces two main types of wall-mounted devices:
1. Traditional model boilers Viessmann Vitopend 100-W;
2. Condensing boilers Viessmann Vitodens 100(-200)-W.
Gas boiler Viessmann Vitopend 100-W
To the countries of Western Europe German company supplies condensing gas boilers models Viessmann Vitodens. In Russia, this type of equipment is not so popular due to its high price of 100 thousand rubles and more. These devices are very a good indicator Efficiency (more than 100%), and the country of origin is Germany.
For Russia and the CIS countries, this company has developed a more budgetary series of wall-mounted gas boilers Viessmann Vitopend 100-W. These models are characterized by a standard (for wall-mounted appliances) efficiency indicator of about 90%, and the price of a boiler that is already more realistic for the consumer is from 700 euros, which is already noticeably lower than, for example, for the same "".
Boilers of the Viessmann Vitopend 100-W series are assembled in Turkey and in some countries of Eastern Europe, they are available in several versions:
- double-circuit with a thermal power of 22, 24 and 30 kW;
- single-circuit with a power of 24 and 30 kW.
Depending on the type of emission of combustion products, gas boilers are divided into devices:
- With closed camera combustion or "turbo boilers", with separate (80/80 mm) and, i.e. according to the "pipe in pipe" type (60/100 mm);
- With open cam or "atmospheric" boilers, with a chimney pipe diameter of 130-140 mm.
The device and features of gas boilers Viessmann Vitopend 100-W
In Russia, turbocharged double-circuit gas boilers have gained the greatest popularity, let's look at them in more detail in the photo below.

2. Primary copper heat exchanger
3. Combustion chamber
4. Gas burner with flame modulation
5. Hydro unit "AquaBloc" with quick couplings "Multi-Stecksystem"
6. Boiler control unit
7. Expansion tank
The boilers of this model have two heat exchangers: a copper primary one, and a compact secondary one made of stainless steel for heating running water.
The three-speed circulation pump "Wilo" with an automatic air vent has been replaced with a better analogue - a pump from a German manufacturer " Grundfos"capable of lifting a column of water up to 6 meters. The membrane expansion tank for models with a rated power up to 24 kW has a volume of 6 liters, and 30 kW - 10 liters.
Thanks to a special hydraulic module AquaBloc with quick connectors Multi-stack system, it has become very convenient to diagnose and repair the main elements gas boiler. This is especially true if you need to quickly replace any spare parts when outside the window subzero temperature air.
The entire hydraulic part of the boiler of this brand is made of high-quality composite materials. Both heat exchangers, gas and three-way valve, flow and temperature, flame and draft sensors are of European production.
Vitopend boilers automatically maintain the temperature hot water and heat carrier, thanks to the automatic modulating burner. The device also has a system for self-diagnosis and protection of the boiler against freezing and overheating, as well as a security group.
Operation control and functions of the Wisman gas boiler
On the front side of the body of the device there is a control unit, with the help of which the temperature is adjusted and the operating modes of the Vitopend model boiler are set. In addition, the digital LCD displays error codes when a malfunction occurs during the operation of this gas heating equipment, as well as boiler operation control indirect heating, if necessary.

5 - button on / off the boiler
Single-circuit and double-circuit gas boilers Viessmann Vitopend 100-W have built-in weather-dependent automation. If you additionally buy a street temperature sensor, the boiler will work, taking into account the weather and the air temperature outside the window, on the street.
In addition, in order to maintain required temperature air in the house, it is possible to install a room thermostat for the Wiesmann boiler. The company produces several types of these control devices under the name "Vitotrol":
– mechanical thermostat type “RT”
- programmable type "UTA"
- with digital display "UTDB"
- with built-in receiver and remote radio transmitter "UTDB-RF"
Set for connecting a warm floor to a Viessmann gas boiler
To connect the underfloor heating system, the company has developed a special kit.
It consists of the following elements:
- pump for circulation;
- thermostatic mixing valve;
- thermal heads with a remote sensor;
- supply copper fittings.
This set automatically supports temperature regime necessary for underfloor heating and prevents the formation of condensate in the boiler.
Having bought such a mounting kit for the Wiesmann boiler, you can no longer purchase an expensive collector group with a pump-mixing unit for underfloor heating.

Device and product description
Gas low temperature hot water boiler flow type low heat output Viessmann Vitopend 100-W, type WH1D is one of the most popular high-performance, economical wall-mounted boilers, and for a potential owner it is especially important: with an optimal ratio between price and quality - cost and performance. The rated thermal power developed by Vitopend 100-W gas boilers, type WH1D, provides the most comfortable and economical heating of residential buildings of various sizes and construction volumes. The heat output of boilers with a closed combustion chamber for space heating and hot water preparation is 24.8/31 kW and 24/30 kW for an open combustion chamber.
Wall-mounted boilers Viessmann Vitopend 100 W are divided into two types: single-circuit and double-circuit. The process of heat exchange in boilers of both types is basically the same and consists in the following: the combustion products of the fuel heat the water (coolant) passed through the lamella-type primary heat exchanger. The main difference between the two types of Vitopend 100-W WH1D boilers is that in addition to the primary heat exchanger, elements of the hot water heating device for hot water supply are installed in the double-circuit boiler. That is why an important element double-circuit boiler Vitopend 100-W WH1D is a plate-type flow heat exchanger of small volume, in which cold water from the cold water supply system is heated by the hot heat carrier circulating in the system. The heat exchanger for hot water preparation is installed on the chassis of the AQUA-BLOC hydraulic unit.
The direction of the coolant flow is set by another important element of the Vitopend 100-W WH1D boiler - a three-way valve. In its state, two positions are possible: in one of them, the hot coolant is supplied to the central heating system, in the other, the coolant goes to the heat exchanger, heating the water for hot water supply. In this case, the DHW mode is considered a priority, to which the valve switches when any hot water flow tap is opened. It controls the operation of the three-way valve of the relay (sensor) of the flow installed in the boiler. Convenient regulators allow you to quickly set the flow temperature of the heating line and hot water.
The Vitopend 100-W gas boiler, type WH1D, provides high hot water comfort with a continuous output of 14.3 l/min (at 30/31 kW). Maintaining a constant temperature of hot water is carried out thanks to electronic regulation and the presence of a temperature sensor on the output line. The DHW temperature setting range is 30 - 57°C.
The Vitopend 100-W WH1D single-circuit boiler is naturally not equipped with a hot water heat exchanger for the DHW system, however, it is possible to equip this type of boiler with an autonomous Viessmann DHW tank, for example Vitocell 100. At the same time, the degree of water heating is measured by a temperature sensor DHW tank, which is connected to the electrical circuit of the boiler (Fig. 16).
The temperature in the supply line or hot water can be controlled from the digital indication on the display. Boilers Vitopend 100 are equipped with a diagnostic system that displays the operating and service status of the device, as well as emergency modes. The pressure gauge installed on the boiler control panel measures the pressure in the boiler system.
Boiler Viessmann Vitopend 100-W, type WH1D has long term service and reliable in operation even with significant fluctuations in gas pressure and electrical voltage. Due to its small overall and mounting dimensions, the boiler is suitable for installation even on the walls of small kitchens or in wall niches in utility rooms.
The main advantages of the atmospheric low-temperature gas boiler Vitopend 100-W, type WH1D wall-mounted:

By design, the Viessmann Vitopend 100-W gas boiler is a rectangular case, inside which a heat exchanger, a gas burner, an AQUA-BLOC hydraulic unit with circulation pump, membrane expansion tank and other elements necessary for the operation of the boiler (Fig. 1). Highly effective thermal insulation of the combustion chamber protects the outer surface of the boiler system from heating.
A modulating atmospheric burner is used in the Viessmann Vitopend 100-W hot water single / double-circuit gas boiler of low thermal power. With smooth modulation control, the burner changes its power within the specified range, maintaining the controlled parameter - the temperature of the supply line at a given level. Therefore, a necessary element of the control system is a temperature sensor and an electronic controller. The modulating atmospheric burner of the Viessmann Vitopend 100-W gas boiler is pre-configured to work on natural gas type "E". A set of replacement jets, which is not included in the scope of delivery, allows the boiler burner to be converted to work on liquefied gas. The built-in gas pressure control switch automatically switches the boiler into operation after a failure in the gas supply.
Removal of combustion products of gas boilers Viessmann Vitopend 100-W with a closed combustion chamber is carried out by means of a separately located fan. The fan parameters are calculated depending on the maximum burner power and aerodynamic drag gas-air path of the heat generator. The air supply is regulated by changing the position of the air damper when the burner power changes.
Heating of boiler water takes place in the primary flow-through lamellar type heat exchanger (Fig. 2). At the same time, in boilers of different thermal power, the number of lamellae also varies. So, for example, in boilers with a power of 30/31 kW, the number of lamellas is 98, and in boilers with a power of 24/24.8 kW, there are 82 lamellas. The total volume of the primary heat exchanger is 1.2 liters of boiler water (Table 2)
Because the heating installation– water-heating wall-mounted single-circuit gas boiler Viessmann Vitopend 100-W, Since the WH1D type is delivered in a state of operational readiness, the boiler automation is pre-set to operate in standard mode at the factory. At the same time, the boiler water temperature setting of the Viessmann Vitopend 100-W heat generator with low heat output does not exceed 76 °C. Primary factory setting can be changed at the discretion of the user in order to create more comfortable living conditions. By resetting the thermostatic controller, it is possible to increase the boiler water temperature and thus the flow temperature. However, the manufacturer recommends that, in order to minimize distribution losses, the DHW system and heat distribution device should be set to a supply temperature of no more than 70 °C. During operation of the gas boiler, the temperature of the boiler water is constantly displayed on the display located on the control panel.

The operating modes are carried out using the built-in controller and are set by the controls on the boiler panel (Fig. 3). All functions of the boiler installation can be set with just two control knobs: hot water temperature control and heat carrier temperature control. At the same time, easy-to-use regulators allow you to quickly set the flow temperature of the heating line and hot water supply.
During the operation of the Viessmann Vitopend 100-W boiler, type WH1D without control device remote control(thermostat), the desired room temperature is set by the “Heat carrier temperature” knob. To maintain the set temperature in the premises of the house to the Vitopend 100-W boiler, type WH1D four types of remote control room thermostats (control devices) can be connected:
– Vitotrol 100, type RT room thermostat for controlling the boiler according to the set room temperature;

Installation instructions
Vitopend 100-W wall-mounted gas boilers have been specially designed for quick installation and reduced maintenance time. Installation of wall-mounted boiler Viessmann Vitopend 100-W, type WH1D should be entrusted specialized organization performing service. However, work on gas equipment may only be carried out by installers who are authorized by the responsible gas supply company.
The room for the installation of a floor-standing single-circuit gas boiler Viessmann Vitopend 100-W must be with normal humidity and meet the requirements of the relevant building codes and standards, in particular SNiP 41-01-2003 "Heating, ventilation and air conditioning". Failure to comply with these requirements may result in malfunctions and damage to the boiler system.
Frost protection and proper ventilation are essential for normal operation of the boiler. So, for example, for the operation of the boiler burner, the required volume of air must be taken from the room, for which it is necessary to install a special duct-air duct that goes beyond the outer wall - into the atmosphere. To prevent drafts in the burner area, the air intake duct must not end directly behind the boiler. With a rated heat output of a gas boiler up to 35 kW, the cross section of the air duct must be at least 150 cm².
It is not allowed to pollute the air of the room for installing the Viessmann Vitopend 100-W floor single-circuit gas boiler with halogenated hydrocarbons, which, for example, are part of aerosols, paints, solvents and detergents. In the event of air pollution by halogenated hydrocarbons, the boiler may only be installed if sufficient measures are taken to ensure that uncontaminated combustion air is supplied. In addition, strong dust and high humidity are not allowed in the room.
To avoid damage and deformation of the connecting pipes of the Vitopend 100-W boiler, use an unsuitable mounting tool and apply excessive force (load) is strictly prohibited. Pipelines connected to the heating boiler during installation and after installation during operation should not experience residual mechanical stresses and loads (bending, misalignment, compression, torsion, tension, vibration, distortions, uneven tightening of fasteners).

Since the Viessmann Vitopend 100-W WH1D gas boiler is supplied ready for direct operation, the main electrical installation connections are made inside the boiler at the factory. Connection installation auxiliary equipment eg the Vitotrol 100 room thermostat or the Vitocell 100-W DHW DHW cylinder is connected to the connections of the boiler controller, so this work, as well as the connection to the mains, must be entrusted to a specialized service provider. For example, the connection of the "L" and "N" cores of the mains cable must be observed, as an incorrect connection can lead to serious injury and damage to the device. In addition, the connecting cables must not come into direct contact with hot parts, as this will damage the cables.
Cable NYM-J 3 × 1.5 mm 2 recommended by the manufacturer for powering the equipment of the Vitopend 100-W WH1D boiler from electrical network, has the appropriate number of cores for external connections. The power supply network must have a neutral wire, and the mains supply cable must have a disconnector that simultaneously disconnects all ungrounded wires from the network with a contact opening of at least 3 mm.
When installing the unit in wet rooms, it is forbidden to connect auxiliary equipment on the controller to the boiler in the zone high humidity. When installing the boiler outside of wet rooms, the connection of accessories to the mains can be made directly on the controller. This connection is controlled directly by the controller's power switch.
The manufacturer recommends installing a gas boiler in the area of the passage chimney through the building structure. The flue gas outlet must be connected to the chimney in the shortest possible way via a chimney. In this case, sharp bends in the gas outlet pipes should be avoided. When installing the chimney, it is necessary to check that the cross section of the chimney pipes and the chimney matches the cross section of the boiler nozzle. A distance of at least 100 mm from the chimney to flammable structural elements must be ensured. If necessary, provide thermal insulation of the chimney pipe.
The well-deserved confidence of customers in Viessmann and the correspondingly high demand for its products, which comply with European UNI-EN standards, were also noted by manufacturers of counterfeit goods. Cheap fakes of Viessmann products have entered the Russian market, which are distinguished by their low price and equally low quality.
The use of such "branded" goods is fraught with the occurrence of emergency force majeure circumstances associated with the use of gas equipment. The money spent to remedy these circumstances is nothing compared to the cost of genuine Viessmann branded products.
If you want to avoid such surprises, purchase original Viessmann products only from official distributors.

Viessmann boilers have good operational properties. The article describes correct installation and installation of boilers, which will allow to realize their full potential and avoid troubles caused by installation errors.
Depending on the type, Viessmann boilers are installed in different ways. It's caused design features heating water-heating unit, its dimensions, weight, method of connection to the chimney, type of fuel.
Installation steps for Viessmann boilers:
Installation various types boilers.
- Solid fuel and gas floor.
These types of aggregates are characterized by increased mass, somewhat larger width, length and height. The devices need the strongest and most reliable foundation, because their weight is the largest in the entire product line of the company. The base is made of rubble stone, brick battle, crushed stone, concrete. The area of the foundation is three to four times the area of the boiler. Usage weak foundation leads to damage to the chimney, violation of the integrity of threaded connections, leakage of coolant and domestic gas, fires, explosions. No less dangerous is carbon monoxide poisoning. Solid fuel type heating devices very demanding on the quality and size of the chimney. When wood is burned, the release volatile substances more than when burning gas and the content of soot in the exhaust smoke is ten times higher. Therefore, the diameter of the chimney channels must be increased. Minimum size channels is indicated in the operating instructions, but in real life it must be made at least one and a half times larger in order to avoid soot overgrowth as a result of using oily or damp firewood. Violated calculation, installation, installation and connection of Viessmann Wiessmann boilers increase the risk of fire and carbon monoxide poisoning tenfold.
- Gas wall.
It does not need a base, because it is fixed to the wall with anchor bolts. Of all the fuel boilers, it has the smallest mass and maximum efficiency.
Connecting the power system.
- A solid fuel heating water heater does not need a special power supply system.
The only requirement is a stoking sheet that protects the floor from the possible escape of coal and protects against fire.
- Gas boiler requires connection to the main low pressure network gas. Prohibited by law
make this connection yourself. This is fraught with gas leakage, explosion, fire, and is dangerous not only for people living in the house, but also for their neighbors. Connection to the gas pipeline must be carried out by specialists with the appropriate education and documents of the established form. After connecting the power, the master without fail will search for and eliminate leaks of household gas.
Connecting the heating system.
The installation of the Wiesmann boiler to the heating pipes is identical for any type and model. The pipes are connected using threaded connections, sealed with fluoroplastic flight (FUM). A properly assembled joint will serve without leaking for decades. The connection of the water outlets of the unit to metal-plastic pipes is carried out using adapters and fittings, and does not require special equipment. If the heating is made of plastic pipes, you will need a special soldering iron. metal pipes heating require welding machine, angle grinder (Bulgarian) and highly skilled craftsmen.
Chimney connection.
Solid fuel and gas boilers with an open chamber are connected to the chimney that exits above the roof ridge with the help of roofing iron pipes. The use of galvanized steel pipes is unacceptable; when heated, zinc begins to be released into the air, leading to accumulation in the body and severe poisoning.
Installation and installation of Viessmann boilers must be carried out by specialists. This is a guarantee of safe and comfortable heating in winter period. Masters will determine the best place for the unit, the optimal location and shape of the chimney, calculate the required size and shape of the foundation, calculate ventilation and fire safety premises. Do not risk the lives of loved ones for the sake of illusory savings.

To ensure normal heating of a house or other building, it is important that the connection of the boiler to the heating system is carried out at a high level, taking into account all existing requirements and norms.
Every year the system gas heating are becoming more and more popular among domestic consumers. There are a lot of reasons for the growth of such popularity, and the cost of the fuel itself is not the main one.
For example, they contribute to the spread of gas heating (including liquefied gas systems):
- Ease of use;
- no additional operating costs;
- minimal intervention in the structure of the building;
- ease of adjustment and heating efficiency.
Connecting a gas boiler: features of the stages
If we talk about such a process as connecting a gas boiler to the heating system, then it is one of the most complex and time-consuming processes that requires certain training and building skills.
It should be noted that the design of boilers complicates the installation of heating equipment in many ways - modern units will not forgive a rough attitude during the installation process, they will require careful study of the instructions and memos developed by the manufacturer.
Nevertheless, it is quite realistic to independently install and connect to the system, and such work will cost much less, and you can win in time.
And their connection with their own hands is a process that can be broken down into four main steps:
- installation of the unit (including fixing to the wall, if we are talking about a wall-mounted boiler);
- connection of the heating circuit;
- connection of the heating system;
- connection to the pipeline.
Each of the stages has its own unique nuances, the observance of which is the basis for a safe and effective work heating equipment.
Installation of heating equipment: the nuances of the process
As a rule, the process during which heating gas boilers are installed should not cause difficulties. In the case of outdoor equipment, it will be enough to install the equipment in full accordance with the instructions carefully prepared by the manufacturer.
At the same time, if a wall-mounted heating boiler is installed in the house, then it is necessary to hang it on a special bracket that comes with the kit.
The selection of the boiler installation site is quite another matter - it must be chosen not only based on ease of use, but also in compliance with certain specific norms and requirements. This is the only way to guarantee the most high level efficiency of the heating device, as well as its safety.
When choosing a place for installing a heating gas boiler, you need to be guided by two basic rules:
- The room where the boiler is installed must be equipped with a window that opens. If this is not available, then at least a small window should be available.
- In the immediate vicinity of the heating unit there should not be all kinds of devices, even a gas meter.
It is not a problem to install a wall-mounted one - for this you will need only a few self-tapping screws, with a diameter of at least 6 millimeters (so that the fasteners are not cut off during operation).
- Installation is preceded by careful verification of all details and surface preparation.
- It should be noted that when choosing the installation location, it is also necessary to take into account that the gas-fired wall-mounted heating boiler must be located at a height of at least 80 cm from the floor and 50 cm from the nearest walls.
- Such distances are defined in standards and requirements and are necessary in order to ensure efficient and safe work boilers.
Tip: It is best to install a wall-mounted gas boiler with two people. Thus, it will be possible not only to simplify the installation process, but also guaranteed to do everything right, without distortions and other defects.
- Connecting a wall-mounted gas boiler to a heating system cannot be imagined without a chimney equipment and a room ventilation system.
- In addition, it is very important to organize an efficient inflow and outflow of air - this will ensure the outflow of gas and flue gases, thereby reducing the level of danger.
- If it is not possible to equip a separate forced ventilation boiler, you can simply purchase heating equipment with a turbine. Such boilers are not uncommon today and their feature is the forced removal of combustion products through a “pipe in pipe” chimney. Withdrawal is made through inner tube, while the external one is responsible for the flow of air.
- Absence a large number pipes and ventilation holes allows you to significantly simplify the installation process of equipment, as well as eliminate various problems.
Connecting the heating circuit to the boiler
Most modern gas heating boilers have an identical arrangement of pipes designed to connect the heating circuit, as well as the gas pipeline and water supply.
If you look at the bottom of the boiler (or, on its photo in the instructions), you can see a gas connection there (usually located in the center), to the right and left of it there are pipes for hot and cold water supply.
Closer to the ends of the boiler there are branch pipes to which elements of the heating system are attached. Moreover, the return line is on the right, and the hot water supply to the heating radiators is on the left.
The return and hot water supply must be connected carefully and in compliance with all norms and requirements. Be sure to use special sealants - materials that can effectively isolate the system, eliminate water leaks during the first start-up.
For water, several basic types of sealants can be used, including both the more traditional tow or paint, and the modern thread sealant. The materials of this group are quite inexpensive, but at the same time, they are extremely effective and efficient, they allow you to get a sealed system that works without problems and failures.
It should be noted that the instruction for connecting a gas boiler also implies the exclusion of debris from entering the boiler.
It's no secret that the water itself, which constantly circulates in the heating system, is not too clean, and if these contaminants get into the boiler, then problems may arise, up to the complete failure of the device.
You can eliminate such a nuisance, for this you just need to install on the pipe reverse water supply filter coarse cleaning. In fact, this is an obligatory step that allows you to significantly extend the uptime of the boiler and increase productivity.
The connection of the heating circuit to the boiler will be incomplete if you do not take care of the shut-off valves. Installation of such plumbing fittings is necessary on the supply and return pipes of water.
Such devices will help in the event of equipment failure to facilitate the repair process, exclude airing of radiators and the occurrence of unnecessary problems.
If you save money and do not install taps, then air and water residues in the pipes that have arisen during the elimination of a malfunction in the pipeline can lead to poor heating premises, accelerated battery wear and, as a result, unnecessary financial costs.
Connecting a gas boiler to the water supply system
Today, the connection scheme for a gas heating boiler necessarily implies a connection to a water supply circuit. Work at this stage is almost the same as connecting the heating system - the difference is only in the diameter of the pipes and the taps used.
- It should be noted that the supply cold water be sure to provide a special cleaning filter, which will prevent all kinds of contaminants from entering the boiler. If you do not install such equipment, then the unit may fail - there are more than enough such videos on the Internet.
- The taps used to cut off the water supply circuits must have detachable connections - the so-called "American". This is done in order to simplify the installation process, as well as in case of unforeseen situations, to ensure a quick replacement of a worn-out crane.
- Similarly with the heating circuit, the cold water inlet pipes are located on the heating equipment on the left side (in relation to the center), and hot - on the right.
Gas pipeline: boiler connection
The first thing I would like to note is that the price of an error when connecting a gas pipeline to a heating boiler is very high. Poor installation work and neglect of safety regulations with the requirements of norms and rules can be the cause of emergencies, up to an explosion.
That is why, when performing work on connecting the gas pipeline to the boiler, you should be extremely careful, and at the end carefully check all connections, paying attention to even the smallest points.
- So, starting work on connecting the gas pipeline to the heating boiler, it is first necessary to connect the branch pipe available on the equipment to the branch gas pipe with a crane installed.
- Taking into account the presence of thin and fragile elements on the heating equipment, the connection of a wall-mounted gas boiler to the heating system must be combined with protection against small debris. To do this, a special filter is installed on the valve that cuts off the gas supply from the main.
Tip: When choosing a filter for a gas pipeline, you should not save money - this can lead to rapid wear of the element and, as a result, failure of the boiler.
- Particular attention must be paid to sealing the gas pipeline and its connections with the boiler. This is an important stage of work, because the gas is much lighter than air and can ooze out of the pipeline if the threaded connections are not tight enough.
There is no need to say what the neglect of such questions can lead to - the consequences are the most deplorable. The main materials for sealing threaded connections are tow and paint - the use of sealing thread and FUM tape is excluded, since they do not guarantee complete insulation.
- The next step towards the implementation of the idea of connecting a gas heating boiler is to install a special flexible connection after the filtration element.
At the same time, it is forbidden to use rubber hoses, because over time, rubber loses its characteristics, dries up and cracks, which leads to gas seepage and an emergency.
- To ensure the most optimal system performance, it is best to use flexible corrugated hoses made of inexpensive, but durable and high-quality stainless steel.
The choice of just such a material is justified by its unique qualities, in particular, durability and resistance to negative impact gas and high humidity.
- As for connecting the hoses directly to the boiler nozzle, this process is carried out simply and without much difficulty. It is enough to simply install the union nuts and sealing gaskets made of paranit.
- It cannot be said that the use of gaskets is mandatory, as it allows you to seal the system, to exclude the occurrence of various unpleasant situations, including gas leaks.
Finishing work on the installation and connection of a gas boiler: what's next
The connection to the gas boiler heating system is almost complete, all systems are connected and in good condition. But do not rush and immediately put the boiler into operation - haste in this situation is unacceptable, since not only the normal functionality of the system, but also the safety of people living depends on the quality of the heating equipment.
That is why, for starters, you need to carefully check and make sure that all the work is done correctly and taking into account existing requirements. Water should not flow anywhere, and gas should ooze - all this leads to negative consequences.
If water is immediately visible - it simply oozes from loose connections - then the gas line will need to be wetted with soapy water and watch for the appearance of air bubbles.
As a rule, if all the stages of connecting a gas boiler to the heating system of the house are performed correctly, then problems should not arise at all - this is a fact that has been verified by many consumers.
IMPORTANT! In the event that at least some minor deviations from the norm and requirements for the process of installing a gas heating boiler are found, they should be eliminated immediately. Otherwise, the operation of the equipment will be not only inefficient, but also dangerous.
The first start-up of a gas boiler is best done in conjunction with gas specialists. Of course, you can do without the help of masters, but in this case it will be impossible to obtain permission from specialized authorities.
In addition, gas specialists, having examined the entire heating system in which a gas boiler is used, will be able to point out to the owner of the house what exactly was done wrong and explain what exactly this could lead to in the future.
Consultations of qualified craftsmen in matters of gas heating are a necessary measure, because this is in itself a dangerous equipment, neglect of which can lead to LETHAL consequences.
