Gas boiler for heating without electricity. Heating without electricity - is a non-volatile gas boiler right for you? What is the difference from the usual

Unfortunately, problems in domestic electrical networks and today in the age of astronautics are still present. In the city, they are not so felt, but in suburban villages, power outages happen with enviable frequency. And the one who solves the problems of heating his home must take this situation into account. Therefore, experts as the best option recommend non-volatile gas boilers heating. Of course, taking into account the fact that a gas pipe has been laid in the village.

So, what is a non-volatile gas boiler? From the name itself, you can understand that this unit works offline without connecting to the network alternating current. It does not have an automation system that runs on electricity, a circulation pump and other electrical devices. Many may say that such heating equipment is the last century. Don’t tell me, today on the market you can buy an excellent gas boiler without any bells and whistles, which, in terms of efficiency, is not inferior to volatile heating devices.

Typically, such boilers are installed in systems where the coolant moves according to the natural laws of physics. It rises by gravity from the boiler up the riser, passes all the circuits to the heating radiators and returns back to the boiler along the return line. Heating with natural circulation of the coolant is not effective in all schemes, so many developers are trying to use a two-pipe version of the distribution of heating pipes, where the ideal subspecies is a collector junction. So if you personally choose a non-volatile gas boiler (floor or wall), then immediately resolve the issue of piping.

Internal organization

Varieties and features of operation

Currently, manufacturers of this type of boiler equipment offer two types:

Wall-mounted non-volatile gas boiler.
Floor unit.

The first option has more compact dimensions and not very high power. The second one is bigger and more powerful.

It cannot be said that these devices are not automated at all. They have various sensors that respond to certain processes. The only thing that the devices connected to them only work mechanically. For example, consider design feature nozzle systems.

In such boilers, two burners with piezo ignition are usually installed (that is, ignition occurs from a battery installed inside). One burner is designed to maintain the wick, it is called the pilot. The second supports the ignition process itself, it is called the main one.

The boiler has a button that must be pressed when the unit is turned on.
This produces a spark that ignites the wick on the pilot burner.
And now the main burner is ignited from it.

Automation

Usually, in such boilers, a mechanical thermostat is installed, with the help of which the mode of heating the coolant in the heating network is set. The temperature sensor is built into the heat exchanger. As soon as the water heats up to the required temperature, a signal is sent to the thermostat, which turns off the main burner. The temperature drops below the set value, the main burner is ignited by the pilot. Here is such a simple principle of operation of non-volatile single-circuit (floor and wall) gas boilers.

If we talk about double-circuit non-volatile gas boilers, then everything is the same here, without any differences. Of course, another heat exchanger is added to its composition, which also has to be controlled. But the principle of operation is the same, and even more so the principle of temperature control. The only thing to note is the fact that in heating boilers of this type there are no models with a built-in boiler. Usually, a separate tank with a heat exchanger inside is connected to double-circuit devices, through which hot water passes, heating the water in the tank itself.

Very often, especially in boilers from foreign manufacturers, a sensor is installed in the chimney that controls the draft. This device is now an integral part of almost all modern models. And it doesn't matter what fuel these units run on. As the saying goes, safety is the most important thing.

Advantages and disadvantages

I would not like to consider this heating unit from such a point, but its advantages are so obvious that consumers would like to show some of its shortcomings. You can not show any product with only one positive side. But let's start our analysis with her.

First of all, it is the lack of electricity consumption. There are two positions here: the first is the complete absence of electrical appliances and devices, which means that there is no need to monitor their maintenance and repairs. Second - no receipts for consumption electric current. Full economy.
There is no need to purchase and connect an uninterruptible power supply, with which you can maintain the heater in working order.
In the design of non-volatile wall or floor gas heating boilers, there is a small number of devices, appliances and assemblies. Therefore, they are more compact and light in weight.
Without exception, all boilers of this category have a fairly high efficiency.
Easy to install and connect, much easier than volatile counterparts.
Presentable appearance. Manufacturers today pay more and more attention to this criterion. Therefore, such a device will fit well into any interior. I would especially like to point out wall models that can be hung in the kitchen or bathroom.
Double-circuit floor-standing non-volatile gas boilers can provide heat and hot water for domestic use large country houses. They have enough power for everything.
High safety performance.

Non-volatile boiler with a boiler

Now for the disadvantages.

First of all, I would like to note that boilers of this type can only work effectively if the pressure in the gas supply line corresponds to the passport data of the product.
A prerequisite is a well-mounted chimney that will provide the boiler with good draft.
An important requirement is perfectly functioning ventilation, with the help of which it will be necessary to remove fuel combustion products from the room.
There are special requirements for such boilers, which are indicated in the operating instructions for the unit. They must be followed strictly and without fail.

Having considered all the pros and cons, it is necessary to draw a conclusion. If you fulfill all the requirements of the manufacturer and regulations fire safety, then this is an excellent boiler that will work offline without connecting to the AC mains. And for many regions this is the best solution.

Don't forget to rate the article.

Heating systems have changed a lot since their inception. The initial concept implied the obligatory summing up of communications and the immobility of the structure. However, they can be installed anywhere, separate from power lines. At the moment, such devices are not much more expensive than traditional ones, because demand allows the production of goods at a reasonable price, which will be available to consumers of any income.

How does an autonomous gas boiler work?

The device is connected to the gas channel and water supply system. Depending on the device, water passes through the system one or more times.

Boilers more complex design equipped sensors and automatic mechanisms protection from overheating and emergency situations.

As part of such equipment there are at least two. When turned on, the piezoelectric element ignites the pilot burner, and from it the ignition is transferred to the main one.

The main burner warms up the heat exchanger and after the device goes into standby and keep warm. When lower temperatures are reached, the process is repeated.

Types of non-volatile boilers

Single and double circuit

As the water passes through the heating element, the temperature rises. Thus it is arranged ( circuit is the path along which the water moves. works on a similar principle, except that the heated water passes through a system of sensors that measure the temperature and send information to the control panel.

If the temperature exceeds the norm, the gas pressure decreases to balance it. If temperatures are critical, the system will turn off the boiler for a while to avoid overheating, after which it will turn on again.

Floor and wall

Certain systems are too heavy or bulky to be mounted on walls, so install them

Another reason is portable pump that can vibrate, thereby weakening the point of contact with the wall. As a rule, only large boilers for large-scale enterprises and warehouses.

Reasons for choosing a boiler without electricity

Equipment Advantages

relatively small dimensions;
a light weight;
ease of use;
no problems with repair and search for parts;
affordable price.

Flaws

slow heating;
the need to replace the power supply;
low power(small heating area).

How to choose the right model?

First you need to decide on purchase purpose. If the boiler is purchased for personal home use , then you should not buy expensive large devices. For heating an apartment or a small private house, a product of an average price category is suitable, with a power of 10-15 kW.
Then it is necessary estimate the budget, which will include purchase, delivery, installation. The last point often does not take part in the calculations, but in vain, because when purchasing an expensive boiler, you need to connect it correctly, otherwise a breakdown is inevitable.
pay attention to online reviews to find out how easy the selected boiler is to operate and how difficult it is to find spare parts.
Consult with your equipment supplier on this issue. Almost all modern firms offer services of departure of the master to the place of installation. The specialist will evaluate the area and furnishings and offer several options for the buyer.

Features of documentation and installation

Before you start installing gas heating boilers, you need to get documents and permission, and prepare the installation site.

Before certification of the project for the installation of gas equipment, it is necessary to resolve all technical issues with the gas service authorities.
Installation work can be carried out only a certified specialist with a license and permission to provide services.
After installing a gas boiler, it is necessary to obtain the approval of a gas service representative that the boiler complies with the norms and standards the current legislation of the Russian Federation. This item obligatory, because the boiler belongs to the equipment with an increased level of potential danger and may lead to an accident.
seal all nodes heating system.
Before installing the gas valve, you must put And .

The boiler room can be located on any floor high-rise building, even on ground floor, in the attic or in the basement. Exception - living rooms. Concerning toilet and bathroom- they have a boiler room better not to do.

Be sure to take care that the room in which the boiler room will be located, and the gas boiler itself complied with all fire safety standards and regulations.

To calculate the volume of the room for the installation of a gas boiler, it is necessary take into account the general thermal power both the unit itself and water heating elements - flow and capacitive.

It must be recalled that installation without permission is violation of SNiP 2.04.08-87. Fine can range from 1,000 rubles to 15,000 for individuals, from 25,000 rubles to 120,000 rubles for legal entities.

If an illegally installed boiler has caused an accident or caused damage, citizen threatens criminal penalty.

REFERENCE! Please note that in the technical passport for a gas boiler, the room for installing the boiler must appear as a boiler room or furnace room. To calculate the volume of the boiler room, you must use the data that are shown in the table below.

Required documents

Calculation of fuel consumption. To the gas service need to send gas consumption calculations per month and per year. If the civil service approves the request of a person, they will be given documents in their hands, technical condition and all work will be completed within 1-2 weeks. If the house already has a gas pipeline, a meter will simply be installed on it. This is also done by government organizations.
Technical condition issued on the basis of a project for the installation of a heating device. This includes not only the installation of equipment, but also pad gas pipes from the utility point to the boiler room.
The project will be agreed gas service workers. In addition to the project itself, you need to provide technical passport and certificate of this device, operating instructions, expert's statement that the equipment is standardized.
A project that has received approval can be carried out.

Installation Rules

Mandatory installation requirements:

REFERENCE! This moment is not regulated by the legislation and installation standards, but the boiler must not be placed near the stove, boiler or other hot objects, since the total power temperature field between them will increase, and automatic control systems will lower the temperature to avoid breakdown. In this case, the sensors will show the norm, and the temperature in the room will be noticeably lower than stated.

Engage in the installation of such equipment alone - not the most best idea , since in case of any breakdown you will have to pay a fine for violating the rules. Such equipment may only be installed gas workers, which means that the responsibility also falls on their shoulders. In addition, do-it-yourself installation implies falsification of documents, because in the project protocol, you will need to indicate the person-installer, and it can only be a gas service worker. If you have all the necessary skills and documents and still want to install your own boiler,

Better to do it yourself diagnosis - visual inspection, checking readings from sensors, measuring water temperature, inspecting ventilation, etc.

Autonomous boiler - perfect solution for heating small house or office space from several floors. Operation, control and diagnostics are absolutely no problems, and the rules and requirements for installation are very loyal.

It is difficult to find a room that would not be suitable for installing a boiler, and if there is one, putting it in order is a matter of a couple of days. In order not to rack your brains with calculations - contact your service provider who will calculate for you the cost of installation and equipment free of charge.

In many regions there are places that are characterized by unstable electricity supplies. This is a serious problem - today living without a stable power supply is extremely uncomfortable. The thing is that most systems installed in own house, depend on electricity - and if there are problems with it, you will have to deal with it.

One of the systems traditionally tied to electricity is heating, which, in the absence or unstable supply of electricity, will not be able to work properly. There are many options for heating equipment - there are various options solid and liquid fuel boilers, when using which the problem with electricity disappears by itself.

However, if a gas main is connected to the building, then the most best solution there will be a gas boiler. Most modern gas boilers are tightly tied to electricity - but you need to get rid of this dependence if the electricity supply is unstable. Help solve the problem, which will be discussed in this article.

Types of non-volatile boilers

All non-volatile gas heating boilers can be divided into two main groups:

Combined. Such devices are produced only in a floor format, which is directly related to the large weight of the equipment, which indicates the impossibility of creating and using wall-mounted non-volatile gas boilers. combined type. There are single circuit and double circuit combined boilers- the first option is intended only for heating, and the second allows you to also provide residents with hot water.
Gas. This category of devices works only due to gas. There are devices with one and two circuits, and the format of the boiler can be both floor and wall.

Choosing a non-volatile boiler

When choosing a boiler that does not depend on electricity, you need to consider a number of factors:

Ability to work with any method of coolant circulation. Natural circulation in the heating system is provided by physical laws, due to which cold water displaced hot. Forced circulation is provided by a pump that creates the necessary pressure in the circuit, but requires electricity to operate. A good boiler will be able to work with equal efficiency both with natural and forced circulation - but if we are talking about not being dependent on electricity, then you need to select a unit suitable for working with gravity circulation.

Ability to work with any heat carriers. Most often, ordinary water passed through a filter is poured into heating systems, but sometimes the circuit is filled with antifreeze, which has an increased resistance to cold. A good non-volatile wall-mounted double-circuit gas boiler can work with both the first and second options.
Pressure in the gas line. The standard pressure value for domestic gas pipelines is 1.270 MPa, but it always makes sense to clarify this point. The documentation for the boiler always displays the pressure at which it is able to work stably, so you need to check both values for compliance.
Possibility of retrofitting. Most boiler models are suitable for conversion to another type of fuel. For example, in many solid fuel units it is possible to replace the igniter and install gas burner.
Operating pressure range. When cold weather sets in, the pressure in the main gas pipeline may decrease - which means that the operating pressure in the boiler will also drop. This moment must also be taken into account when choosing a boiler and choosing just such a unit that can work in such conditions.

All wall-mounted double-circuit non-volatile gas boilers are highly reliable and easy to operate. In addition, if properly installed, such equipment has a high degree of safety. Thanks to the built-in automation emergency situations the boiler just shuts off. Also, the design of the boilers includes a thermostat that monitors the temperature of the coolant and automatically starts the heating mode if necessary.

On the market you can find a lot of models of both domestic and foreign production. Choice of the most suitable option cannot be called obvious - for example, foreign devices are more economical and efficient, but they are also more expensive. Domestic non-volatile wall-mounted gas heating boilers are also quite reliable, cheaper and often fit much better into domestic realities.

Installation

Any gas equipment can only be installed and put into operation if there is an installation project and after agreement with the gas service. If the project is executed with errors, or if they were made during installation, the boiler will not be allowed to use.

In order for the boiler to work normally, a number of conditions must be met:

A positive temperature must be constantly maintained in the boiler room;
During the installation of the boiler, it is necessary to observe fire fighting instructions(for example, the walls near which the boiler is installed must be protected with non-combustible materials);
At self installation boiler for its first start-up, it is necessary to invite a specialist who can make sure with an experienced eye that the boiler is installed correctly and that there are no errors in its operation.

When designing a boiler installation scheme, you need to think not only about the unit itself, but also about the installation of a chimney system. It is necessary to install a chimney in accordance with a number of requirements, which depend on the characteristics of the boiler and the characteristics of a particular building. Each individual boiler must have its own chimney, but if necessary, several boilers can be reduced to one flue duct, the cross section of which corresponds to the sum of the cross sections of the outlets of each boiler.

According to the standards, if the chimney is led to the roof and installed at a distance of 1.5 meters from the ridge, then the height of the pipe must exceed 0.5 meters. In the event that the distance between the ridge and the edge of the pipe is from 1.5 to 3 meters, the chimney must be brought out at least on the same level with the ridge.

It is recommended to make the chimney completely straight, but if this is not possible, then several turns can be made (no more than three along the entire length of the chimney). The total length of the chimney must exceed 5 m. From above, the chimney is closed with a metal fungus, which prevents dirt and moisture from entering the structure.

A private version of the chimney is coaxial pipes, the possibility of using which is determined individually (it is advisable to consult a specialist). Coaxial chimneys can be installed at a low height and lead directly to the wall. Installation is inexpensive, and its technology is extremely simple.

Among the disadvantages of coaxial chimneys, one can note some dependence on forced air draft, which is created due to electric fan. When installing such a chimney in combination with a non-volatile gas boiler, the reliability of the system will be reduced. In addition, condensate constantly appears in coaxial chimneys, and the difficulty of removing it is also a disadvantage.

Popular boiler models

As mentioned above, there are many different non-volatile boilers with a wide range of characteristics and additional features. In all this diversity, there are several models that are most in demand among users. It is worth familiarizing yourself with these models in order to have good example the most requested features.

Boiler Viadrus G36 (BM)

This model of a copper is issued with a power range from 12 to 49 kW. It is necessary to select a specific modification taking into account the requirements for individual features heating system and buildings.

Viadrus G36 is a wall-mounted gas boiler that can work without electricity. The design of the boiler has a special thermoelement that ensures uninterrupted operation of the gas valve. The system is also equipped with a sensor that prevents various abnormal situations arising from traction.

The boiler of this model is quite efficient and can heat the coolant to temperatures from 45 degrees. If necessary, a circulation pump can be connected to the boiler, providing forced circulation coolant in the system. If the supply of electricity in the local network is not stable, then the system should be supplemented with a good uninterruptible power supply.

It is best to install such a unit together with a separate chimney, but if this is not possible, then a coaxial pipe is quite suitable. The boiler has special pipes to which an indirect heating boiler can be connected to provide residents with hot water.

Boiler Protherm Bear TLO

Another popular line of non-volatile boilers is Protherm Bear TLO. The power of the units of this line varies from 18 to 35 kW, and both main and liquefied gas. Such boilers have a lot of positive characteristics, which determines their popularity among users.

Protherm boilers can be used in heating circuits open type. The design of the boilers includes a piezo ignition system, an open combustion chamber, a gas burner made of of stainless steel and cast iron heat exchanger. All these elements and high-quality assembly allow boilers of this brand to provide efficiency from 87% to 92%.

Power adjustment is carried out stepwise. It is possible to transfer the boiler to summer and winter mode. Fine tuning and adjustment of the boiler operation is carried out automatically due to the built-in electronic unit. The draft level of the chimney is also adjustable.

What is important, Protherm devices have a lot of protective features. So, the heat exchanger is reliably protected from the effects of condensate. The boiler has built-in overheating protection, a system that controls the level of the flame, and a device that monitors the pressure and temperature of the coolant in real time, and also maintains them at the proper level.

All these characteristics allow us to talk about the high quality of these boilers. In addition to the advantages described above, Protherm Bear TLO boilers differ small size, pleasant design, as well as ease of installation and use, which even an inexperienced owner can handle.

Conclusion

Non-volatile boilers are the optimal solution for not paying attention to interruptions in the supply of electricity. It is necessary to select the boiler depending on the specific operating conditions so that it can fully show its capabilities.

The system, if I understand correctly, already exists. The coolant will not go through the boiler without a pump - energy dependence.
temperature without electricity hot water in the boiler cannot be higher than the heating temperature. If in autumn, in spring the temperature of the coolant is 40-50 degrees, then what DHW temperature expect? And how long will it take to warm up?
You have a serious expensive house, do not fool around with the energy independence of the boiler.
Well, judging by the footage, then my house is even more serious. And hardly any cheaper.
I am heated with electrically independent CO.
What is "do not fool with the energy independence of the boiler" I would like to hear an explanation from you.
With an electrically independent SO EC, there is one minus - fuel consumption is 1-5 (in words - from one to five)% more.
This is all. In the case of the presence of main gas, this difference is comparable to the measurement error.
Of the advantages of the SO EC (which you already have) - you think about your heating once a season - in the fall on the subject of "whether it was worth cleaning the sump" and the routine maintenance of the boiler, as well as any boiler, regardless of the type of CO. And you have nothing to advise your neighbor (who thoughtlessly did the PC), running with mats from the generator to the house and back in the middle of the night.
Further - if you don’t want to tinker with the organization of a separate exhaust pipe for the column - you can study topics about double-circuit boilers.
There are two opposing opinions here - one is not enough, the other is quite comfortably enough for a double-circuit for hot water supply. I didn’t have such a question, because I can’t say the specifics, except that the Bosch double-circuit is enough for my neighbor. He is not inclined to lie, but a family of 5 people.
Well, and one more thing - you are wrong about the indirect heating boiler in CO. Works with a bang even in the EC.
Works even as a protochnik.
I will also buy a generator. Just in case. To improve comfort. But only !
"Do not fool" is necessary not with electrical independence, but with an unreasonable increase in the number of devices (each of which can also fail or fail) in home heating system permanent residence, which is essentially life support system.
You are somehow more careful with your statements or something. To give out such errors and the truth is not good.
I may be in the minority, but I am a supporter of the conservative method. That is, a non-volatile floor speaker, a gravity-fed system ... A pump in the system as an option is welcome. For hot water, a column is better, as an option, a boiler with a water heater ... Of course, in terms of the level and location of comfort, it cannot be compared with wall hangings, but sometimes in some cases, like yours, it's worth it ...
As for the choice of a boiler, for your home, so that 35 kW with a Honeywell or 820 Nova valve is enough with a margin, you can at least reduce the gas consumption ...
Then you and I will be in the minority already together.
CO is already there and it is EC! In other words, the author was lucky and quite strong (nowadays, few people will undertake to make an EC).
AOGV can be replaced with anything imported. Many foreign manufacturers produce gas automatic very economical boilers for EC.
For example, proterm has a "wolf" http://www.teremopt.ru/about/news/200642.html or TLO http://www.komuteplo.ru/TLO
And not only them.
A more budgetary boiler of a similar format is a lemax with eurosit automation. Thousands at 12-15 in the Moscow region.
you want - steel http://lemax-kotel.ru/index.php?option=com_virtuemart&Itemid=66
you want - cast iron http://lemax-kotel.ru/index.php?option=com_virtuemart&Itemid=84
I know several owners who switched from AOGV to Lemax with Eurosit. Only one had an assembly defect and the boiler was promptly replaced by a representative of the plant with a new one.
Have been working for more than one season. There are no questions for them yet.

Autonomous heating systems based on gas boilers are considered the most convenient and efficient.

They almost do not need constant attention, are able to maintain a constant temperature, have protection against possible problems- overheating, flame extinction, other malfunctions.

However, most units are too dependent on the availability and quality of the power supply.

Any voltage drops cause failure of the control board or other devices, and a power outage completely stops the heating system.

To solve these problems, non-volatile gas boilers are used.

Non-volatile gas boilers operate only with the help of mechanical components and parts. They do not need the use of electricity, which greatly increases their capabilities.

In the conditions of Russia, where winter time the temperature drops well below zero, it is important to ensure the continuity of the heating systems. At the same time, most power networks are overloaded, and in some villages there is no connection at all.

This makes non-volatile boilers popular and preferred units. All the main components of the unit are controlled only by mechanical methods, but this does not impair the quality of heating the house.

Non-volatile boilers are devoid of many parts, which simplifies the design and makes the operation more stable and reliable. Most users do not consider the lack of opportunity remote control and others additional features a significant disadvantage.

Everyone understands that a lot of add-ons make the device more vulnerable and unreliable.

NOTE!

The design of non-volatile boilers arose much earlier than more modern dependent units. Long term existence allowed manufacturers to work out assembly technologies and achieve high performance.

What is the difference from the usual?

The difference between a non-volatile boiler is the absence of all nodes that need power. No built-in circulation pump, turbofan.

Management is carried out using mechanical devices - valves, mechanical sensors, regulators. This makes the design very simple and reliable, but all processes take place in a natural way.

For example, smoke removal is carried out using stove draft in the chimney. The air is taken directly from the room. These features make the operating mode dependent on the mass of external factors..

For example, draft in a chimney varies with the weather, direction and strength of the wind. Drafts can blow out the flames. In addition, the room needs good ventilation, since the boiler actively burns out oxygen.

Many users solve these problems by installing external devices - a circulation pump and a turbo nozzle to increase and stabilize thrust. This makes the mode of operation more intense and even.

Advantages and disadvantages

The advantages of non-volatile boilers include:

there is no dependence on the availability and quality of power supply;
simplicity of design, lack of minor details;
guaranteed continuity of the process of heating the house;
boiler cost and repair work significantly lower than that of volatile models;
maintenance and cleaning can be done independently.

the protection system is limited to a few sensors;
there is no possibility of remote control;
The operation of the boiler depends on external factors that cannot be adjusted.

Despite some drawbacks, non-volatile boilers are a practical and reliable solution. In some settlements, they have no competitors due to power outages.

Device

The main elements of non-volatile units are the primary (main) heat exchanger and gas burner. They provide the main function of the boiler.

In addition, the design contains:

three-way valve, in which the temperature of the coolant is reduced to a predetermined value;
gas equipment providing control and fuel supply;
secondary heat exchanger (only for double-circuit models);
temperature and pressure sensors.

The list of nodes is small, but this is the main advantage of non-volatile boilers. The fewer parts, the higher the strength and load resistance of the structure as a whole..

Kinds

There are not as many varieties of non-volatile boilers as more modern dependent models. For example, there are no turbocharged units (with mechanical air supply).

There are the following varieties:

single-circuit. Provide only heating of the coolant for the heating circuit;
double-circuit. They perform two functions - heating the coolant and preparing hot water.

According to the installation method:

wall. Installed hinged way on bearing walls or strong vertical surfaces;
floor. mounted on the floor or non-combustible stand. Most non-volatile units are made in the floor version;
parapet. These are units that have the characteristics of several groups of gas boilers. They have a lot of features that make them practical and user-friendly.

NOTE!

As a rule, non-volatile boilers have a floor single-circuit design. This is the easiest and most reliable option. This approach makes it possible to guarantee an uninterrupted supply of coolant to the heating system in difficult conditions.

Principle of operation

The operation of a non-volatile boiler is based on the flow heating of the coolant in the flame of a gas burner. The liquid enters the boiler, goes through the heating stage and enters the three-way valve.

There, a colder "return" is mixed in a certain ratio. This allows you to give the coolant the temperature set by the mode. If the boiler is double-circuit, then a secondary heat exchanger is installed between the main heat exchanger and the three-way valve for preparing hot water.

Smoke is removed by natural draft, so a connection to a common house chimney of sufficient length is required.

Fluid circulation also occurs naturally, which requires compliance with the standard slope when installing the system.
