Floor gas boiler: which one to choose, reviews, expert advice

Private construction was popular before, but recently it has been gaining even more turnover. One of the first questions that arises at the stage of building design is the following: what type of heating should be installed in the future house? The most common is a floor gas boiler. Which to choose? Reviews on this topic are quite controversial. Therefore, you should first find out what gas heating is, what difficulties can arise when it is connected and operated. And then study the reviews on some models of this type of equipment.

The structure of the gas heating system

Such a system implies the presence of:

• Boiler room. This is the room in which the AOGW floor-standing gas boiler is directly located and a number of devices regulating the operation of the system. Depending on the complexity, the number of control devices may increase.
• The pipeline. This communication makes it possible to move the heated water to different rooms. Posting can be hidden or open depending on the project and the wishes of the customer. Sometimes the pipeline is also used as an element for installing a warm floor. Connection can be single-circuit or double-circuit. In the first case, as far as the distance from the boiler, the pipes will lose the set temperature mode, since the connection is obtained in series. The second option provides that the installation itself and the material will cost much more, but it will allow you to adjust the temperature of each room separately. In this case, it is easy to organize and regulate the supply of hot water, regardless of the season.
• Convectors. Or, in Russian, ordinary batteries. With their help, you can increase the area of ​​thermal return.

As you can see, the pipeline and convectors are identical to the usual heating system of the apartment.

But the gas boiler floor for the home and control devices are already more complex components. In addition, a number of approvals will be required to connect private equipment.

Project documentation. Coordination with the authorities

Gas heating is a source of increased danger, therefore, in order to carry it out, it will be necessary to develop a project and coordinate it with certain services. First, an application is written to the supervising gas supply authority. You will need to indicate the planned consumption. It can be calculated knowing the future heated area: it must be divided by 10 kW per sq. m. The resulting figure will be approximate. For an accurate calculation, you need to know the heat loss, as well as the amount in the heating system. Qualitatively, the boiler can warm up 12 liters. For this, 1 kW will be spent. Recently, a region coefficient based on the average annual temperature and season duration has been applied to these calculations.

The term for consideration of the application in this instance may be a week. After that, the technical conditions for the development of the project are handed out. Next, you will need to correctly design the wiring diagram, according to the received data.

You cannot do this yourself. Project documentation is performed by organizations licensed for this type of activity. After the project is completed, you will need to collect an additional list of papers relating directly to the equipment: examination of compliance, technical passport, certificate, instructions. The entire package of documents received is referred to the gas supply organization for approval. The process, depending on the season and complexity of the facility, can last from a week to three months. After obtaining permission, you can proceed with the installation. If the refusal is received, then the reason will be written in it. Finalization of the project and re-approval will be required.

Specifications for connection

Only an organization and its employee who are licensed to carry out such activities can install a gas boiler for outdoor use. You yourself should never do this yourself. To install the heater, the following specifications must be provided:

• There should be free access to the device at any time.
• The size of the opening to the boiler room is at least 800 mm.
• The boiler room area is at least four square meters.
• Ceiling height - at least two and a half meters.
• Mandatory supply of water to the room.
• Walls and floors should be covered with non-combustible materials: tiles, plaster.
• Be sure to install a chimney of the required diameter.
• If the heater will work with the connection to electricity, then the socket must be arranged with grounding.
• Be sure to have an opening window that will serve in necessary situations as a light source and extractor fan.
• The floor must be level.
• The presence of supply and exhaust ventilation.

Do not install gas equipment in rooms without ventilation, dormitories, as well as in bathrooms, corridors, basements, on balconies and ground floors. Equipment should not stand close to walls lined with combustible materials. As you can see, floor-standing gas heating boilers require fairly harsh conditions for their connection. But, having completed all the points, you can not be afraid for the safety of using such equipment.

Assembly of units

Floor gas boilers for heating a private house should be installed and connected by specialists licensed for this type of activity. Most often, employees of the gas supplying organization do this, but are related to the after-sales service. The same unit will then be responsible for the maintenance of the unit.

Heating wiring around the house, the installation of the boiler can be done by yourself. But the insertion and connection should be carried out only by a licensed specialist. This condition is mandatory. Otherwise, the connection will be considered illegal and dangerous to others. The master does the installation based on the diagram and equipment passport. The same goes for the chimney. He must undergo a survey and verification of fire safety.

Installation of the system should be carried out at a temperature of +5 to +35 degrees Celsius. In order to ensure the safe use of gas heating, the operating instructions should be followed. It is worth noting a number of general points:

• Before turning the equipment on for the first time, check the tightness of the pipe feed. This can be done by spreading soap and water at the junction. If bubbles appear, turn off the gas supply, ventilate the room and eliminate the leak.
• Do not subject the device to mechanical impact. The case of gas equipment is not designed for shock.
• In the event of a gas odor during operation, call the emergency service. Do not attempt to repair the damage with your own hands.

Types of boilers

This type of equipment is considered very reliable. He has a high coefficient of heat transfer - 90-93%. Floor gas heating boilers have gained their popularity due to its high efficiency, the ability to heat areas from 100 to 800 square meters. m. A wide range of products allows you to choose the device that will meet the technical needs and financial capabilities of the buyer. The complete set of such devices can be different: from the simplest to the most automated. For areas where power surges are noted, you can use the device without connecting to the network, which will save on further operation.

Typically, devices are sold along with temperature sensors, which, when the required temperature is set, switch the device to an economical mode of operation. For this type of heating device, two types of material for a heat exchanger device are characteristic:

• Cast iron. This raw material is not subject to corrosion. Burnout is virtually ruled out. Such a heat exchanger can last up to fifty years. But he is afraid of strong mechanical stress and a sharp temperature drop.
• Steel. Resistant to cracking and deformation. But subject to corrosion and burnout. Pluses are a lightweight product, an inexpensive price. The life span of such a heat exchanger ranges from 5 to 15 years.

Until now, devices with copper heat exchangers can be found. But this material is expensive and is prone to burnout.

Distinguish another classification. On the combustion chamber, the devices are:

1. Open type. With this form, oxygen for combustion is taken from the room, and the combustion products exit through the chimney.
2. Closed type. For this option, a chimney device and forced-air and exhaust ventilation are not required. Because the unit does not draw air from the room, and the smoke removal system is included in the set of equipment.

According to the type of burners, atmospheric and inflatable boilers are distinguished. The first ones work less noisily. Differ in the low price. The burner is usually part of the apparatus. in the second, air is injected using a fan, therefore higher noise. Necessarily require a connection to the mains. Most often sold separately from heating equipment. The cost is significant.

The installation of heaters depends on the type of fluid circulation in the system. It is forced and natural. In the first case, it is mandatory to connect to the mains. There is an increased speed of circulation, which allows better heating of the room. In the second case, you will encounter a fairly complicated installation. But it will be possible to connect to the simplest mechanical boilers. For proper operation during installation, a certain slope of the pipeline must be observed. As for floor-standing equipment, it can be divided into two large groups: single-circuit and double-circuit.

Single-circuit gas boiler floor

This type of heating unit is one of the most popular.

Consider its advantages:

• Profitability. The cost of this equipment option is much lower than analogues - no more than 20 thousand rubles. And if you still choose a Russian floor gas boiler, the price will surprise you even more. In this case, the quality will be up to standard. Do not forget about maintenance. Repair of a domestic unit will cost significantly less.
• Simple design, easy to maintain. Easy to operate.
• It can heat large areas.
• Economical gas consumption.

The gas single-circuit floor boiler can be produced with a closed and open combustion chamber, with a steel or cast-iron heat exchanger. There are automated models. The disadvantages include the fact that for a hot water supply system you have to buy a separate water heating system.

So, we want to buy a floor gas boiler. Which to choose? Reviews recommend that such a device be bought in houses and apartments that have central hot water supply. Below we consider dual-circuit systems.

Double-circuit gas boiler

The price of this type of equipment will differ from the first option (from 20 to 80 thousand rubles). But then there are a number of additional advantages:

• An opportunity not only to heat the room, but also to heat water for household needs, regardless of the season.
• High heat dissipation.
• A wide range of models equipped with automation.
• The ability to install additional temperature control systems in various rooms.
• With automated systems, operational safety is increased several times. If a malfunction is detected, the system can stop the operation of the device.
• Reliability through self-diagnosis.

It should be understood that when the choice falls on a gas dual-circuit floor boiler, the price will depend on the number of automation and additional functions. The same can be attributed to the main disadvantages:

1. Dependence on electricity. In the event of a power outage, the heating system will not work, which will be critical in regions with a low temperature in winter. Such devices are not recommended to be installed in areas with unstable voltage. Automation can quickly fail. In addition, additional operating costs are required.
2. The price can be quite high - up to 100 thousand rubles.

What to consider when choosing equipment?

Choosing a gas boiler floor, price and technical data will play a major role.

When considering models, the following factors should be taken into account:

• Heater power. An important indicator. As a rule, for single-circuit boilers, heating power is laid. And for double-circuit should also take into account the estimated water flow. With an incorrect calculation in the second embodiment, you can get a deplorable result in the form of poor heating. It is recommended that you stock up on this type of equipment.
• Fuel consumption. It also affects the efficiency of the equipment. Depending on the flow rate and power, you should choose the best option to minimize operating costs, but get high-quality heating.
• The material from which the heat exchanger is made. As stated earlier, a cast iron floor gas boiler with proper operation will last at least twice as long as a unit with a steel heat exchanger.
• Automation. The smarter the heating system, the safer. It is not recommended to install in areas where there are power outages or sudden surges. Under such conditions, the system will quickly fail. And do not forget about the important condition: the more the system will have automation, the higher the price.
• Type of burner. Inflatable or forced. The second option will be more productive, but more noisy. It is recommended for rooms with a large area. But for inflatable, the optimal heating area is up to 200 square meters. m
• Manufacturer. Undoubtedly, domestic equipment will cost significantly less. And in addition to this, you can get quicker and cheaper repairs in the event of a breakdown. Import manufacturers are characterized by a longer service life, minimization of breakdowns with proper operation
• Consumed electricity. This indicator indicates that a connection to the electrical network is required. And its size depends on additional costs during operation.
• The ability to control the temperature. It should be noted that a number of the simplest boilers also have this feature. In this case, the temperature of water heating changes. In automated systems, it is possible to install a temperature sensor in rooms, with the help of which the device itself will regulate the gas supply.
• When choosing a double-circuit boiler, you should pay attention to the possible temperature of hot water, as well as the heating time.

Why do most buyers for a heating system choose a gas boiler floor?

The price of gas, as fuel, remains the most attractive. Plus, add durability to the equipment when used properly and ease of maintenance. In the event of a breakdown of old equipment, you can easily connect a new device to the existing system. Separately, it can be noted that the market offers a wide range of floor gas equipment, which at a different price range has decent quality. One of such devices is the Czech floor gas boiler Proterm.

Which manufacturer's equipment to choose?

If we consider domestic manufacturers, then, unfortunately, the quality is still inferior to import options. However, do not forget that at the same time the price remains low. But subsequently, more frequent repairs may be required. And ultimately, the service life is lower than stated. Among other things, the domestic manufacturer is still inert. And often the modernization of the lines can not afford because of the lack of free finance and modern developments.

So, we need a floor gas boiler. Which to choose? Reviews in large quantities recommend considering the Czech version. The floor gas boiler "Proterm" is available in several versions. In the context of the types of floor units there are economical options. There are also the most automated devices. One of the most popular systems of this type are floor gas boilers "Bear". The manufacturer has a fairly wide range of quality equipment. Options are different.

Power can be selected exactly as required. The heat exchanger is made of high quality cast iron. In addition, there are various options for picking automation. Based on your needs, you can choose exactly the model that is most suitable. The price varies from 40 to 140 thousand rubles.
