Use the gas floor boiler for home or apartment heating is considered the cheapest and qualitative option. To date, this issue is quite relevant, therefore there is a wide selection of modifications of both domestic and imported producers that differ not only at the price, but also the presence of various functions and additional options.
To independently understand the sentences and choose a good, economical outdoor gas boiler, you need to analyze a lot of information that will help you choose the optimal option.
Principle of operation
Gas heating device
Almost all floor gas boilers work identically. For their operation, natural or liquefied gas is used as a source of energy, which, during combustion, heats the heat exchanger inside it.
The latter is water that heats up and circulates through the system. In this case, for high-quality heating of the room, you need to choose a device with a high-quality heat exchanger.
It can be conventionally divided into several categories that differ in the material from which it is manufactured:
- Cast iron. It is recognized in the most durable, since it is not subject to corrosion and has high resistance to exercise. There are many cases when such an element worked 50 years. Among the disadvantages can be called that cast iron is considered fragile material. A sharp drop of fluid temperature inside it or mechanical impact may damage the case.
- Steel. Floor boilers with a heat exchanger from steel are significantly easier and more resistant to possible shocks. But a significant drawback reduces their positive characteristics. First of all, this is due to the fact that the metal will procee much faster than cast iron, besides, it is subject to corrosion. Therefore, the average life of such devices is significantly lower and is only 10 years.
To compare the efficiency, which has gas floor boilers, a table analyzing the use of heating devices operating on different types of fuel is given.
The information is presented on the example of heating for a private house with an area of 350 m2. These are given in the average value at the rate of 6 months of the heating season.

Single-mounted
A single-mounted floor boiler is considered the most common. The advantage in its use is the following characteristics:
- Efficiency. The cost of such boilers of domestic production varies in the region of 20,000 - 30,000 rubles. In addition, long-term operation is confirmed by reviews;
- maintainability. If some types of imported devices find the item of interest may be problematic, it will be found in the Russian heating boiler in every city. And you can make a small repair with your own hands;
- Lack of complex electronics. It makes it easy to maintain it and use without learning;
- Low gas consumption.
Gas boilers for the heating of a private house are with an open or closed combustion chamber. The difference is that the first functioning is used by fresh air of the room, and the carbon black gas is excreted through the chimney.
The second - with the help of fans they take air from the street and similarly remove the exhaust gas outward. The work of the open boiler occurs on the principle of the gas burner: they are heated and heated the air around themselves. From this we can say that the efficiency of them is significantly lower than that of closed, from which everything is warm in the heat exchanger.
Single-mounted floor heating boilers are recommended to be installed in homes or apartments with centralized hot water.
Double-circuit
The cost of such a device will differ from one-contact 20 - 30% per largest. But this is explained by a number of reasons characterizing him with a positive side:
- high heat transfer;
- Performing a double function: heating and providing hot water;
- A wide range of options equipped with electronics, which allows us to talk about reliability and self stop when a malfunction is detected.
Installation of a dual-circuit floor gas boiler does not represent a special complexity. To do this, you need to connect it to the heating pipeline and connect with a water mixer. After that, contact the specialized workshop to call the wizard, which connects the boiler to the gas pipeline and will first launch the device.
Considering the principle of operation, you can allocate 2 basic actions:
- During the discovery of the hot crane, a heat exchanger gas supply is shutdown;
- In this case, the operation of the burner is shifted to heat the contour associated with the heated of the water supply. At the same time, the heating procedure itself is carried out in flow-up without the use of accumulative capacities.
Separately, it should be noted that the automatic shutdown based on the electronics will only work in the presence of power supply. When the power is turned off, the functionality of such equipment will fall sharply.
Special requirements
Modern gas floor boilers meet all safety requirements and comply with regulations. In some cases, the use of combined devices is practiced, in which when the gas supply is disconnected, the system automatically overlaps the valve and starts it from the electrical network. All for both the installation of a double-circuit boiler, see this video:
The most simple models are not equipped with automatic, so you need to switch them with your own hands. Therefore, it is recommended to periodically check its performance with possible disconnections.
Trust the installation of boiler to specialists
Gas is considered a source of increased danger, because to connect the gas boiler in a private house, it is necessary to invite a specialist licensed to carry out this activity.
During the construction of a private house to the question planning, it should be considered very seriously. The fact is that the installation of the gas floor boiler is allowed only when all conditions are met. They are regulated by the requirements prescribed in SNiP and Fire Safety Safety. Any non-compliance or deviation from them will lead to the fact that at best, with a periodic check, the owner will receive an administrative penalty, and at worst it will end with an explosion or fire.
These requirements do not apply to electric boilers, it is allowed to install them anywhere. But to achieve a disorder of aesthetics of the premises, it is recommended to use a special room for these purposes.
Advantages and disadvantages of AOGV
AOGV optimally on fuel consumption and heat transfer
Outdoor gas boiler for heating a private house is considered the most popular for re-under construction or repaired buildings.
When contacting a specialized organization with a question, what equipment to establish in order to drop your house, most likely you will get an answer that it is the floor AOGV. First of all, this is due to the fact that in the ratio of consumption of material and heat transfer, gas leads in this ranking.
Dignity
Main checking Installed gas boiler will be held in winter
The wide popularity of gas floor boilers for heating residential and non-residential premises is explained by the fact that such equipment has a number of advantages that are distinguished from major competitors.
First of all, it is a significant savings, the ability to perform partial installation with your own hands, simplicity for further maintenance and ease of operation. In addition, you can allocate a number of advantages of such equipment:
- The automatic boiler set in the house allows you to leave it unattended without any concern that the fire will go out, and the house will remain in a strong cold without heating. Even if such a situation occurs, the sensor will give a signal for the electrical ignition system, which will again start the burner by feeding to it and open the gas valve.
- The efficiency of the gas boiler in a private house is quite high. It highlights much more energy than consumes.
- It is allowed to install a floor boiler with their own hands, the only requirement is to ensure that the gas connection is carried out by a qualified specialist who has an appropriate license.
- With it, you can dump both large houses and non-residential production facilities.
disadvantages
If you are afraid of the fire, do not choose devices with an open burner
Despite the fact that the floor gas boiler has such weighty advantages, before you give preference, you should familiarize yourself with the special conditions for its design and operation that can be presented as disadvantages of such equipment.
For some, they may seem insignificant, and for others, opposite - weighing. Here are the main of them:
- Before installing floor heating gas boilers, you need to collect a lot of permits. For example, coordination from the service of the State Technical Support, to provide a project of the upcoming installation, the act of checking the chimney, the plan of the room in which a certain place is assigned to its installation.
- The weak pressure in the gas pipeline may lead to what they begin to smoke, as a result of which the chimney is clogged and the efficiency of the equipment is reduced.
- Select devices with an atmospheric burner are undesirable to people who are fear of open fire. This is due to the fact that in such boilers the flame is in sight.
Being before the question, how to choose the best option for your home, you should pay the advantage of boilers equipped to operate in Russia.
This is due to the fact that the pressure in the system can change significantly, therefore, decreased to the minimum level, the import burner can begin to burn itself, which will lead to the failure of the entire boiler.
Choosing a boiler
What is the best floor gas boiler to buy for your home? This question is asked almost everyone who faces its acquisition. In this case, it will be faced with the following issues:
- one-connect or double-circuit;
- imported or domestic;
- with an open burner or closed.
Deciding all these questions, the problem of determining the power of the device will rise. It should be noted that this value directly depends on the area of your home, the presence of warm pilaments in it, which is heated by some rooms, the number of living and a number of reasons. For details on the choice of a furniture for a country house, see this video:
For approximate acquaintance with the calculation methodology, you can use the table below.
