Floor gas boiler: what to choose, reviews, advice of a specialist

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

Structure of the gas heating system

Such a system implies the presence of:

• Boiler room. This room, which houses the floor gas boiler AOGV and a number of devices that regulate the operation of the system. Depending on the complexity, the number of control devices can increase.
• Pipeline. This communication makes it possible to move the heated water to different rooms. Wiring can be hidden or open depending on the project and the customer's wishes. Sometimes the pipeline is used and as an element for the device of a warm floor. The connection can be single-circuit or dual-circuit. In the first case, as far as the distance from the boiler, the pipes will lose the given temperature regime, 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 to regulate the temperature of each room separately. In the same case it is easy to organize and regulate the supply of hot water regardless of the season.
• Convectors. Or, speaking in Russian, ordinary batteries. With their help, you can increase the heat input area.

As you can see, the pipeline and the convectors are identical to the usual heating system of the apartment. And here is a gas boiler floor for home and regulating devices are already more complex components. In addition, a number of approvals will be needed to connect private equipment.

Project documentation. Coordination with the authorities

Gas heating is a source of increased danger, therefore in order to conduct it, it will be necessary to develop a project and coordinate with certain services. First, an application is written to the supervising authority of gas supply. You will need to specify the planned consumption. Calculate it can be knowing the future heated area: it must be divided into 10 kW per square meter. M. The figure will be approximate. For accurate calculation, you need to know the heat loss, as well as the amount in the heating system. Qualitatively the boiler will be able to heat 12 liters. This will cost 1 kW. Recently, these calculations use the coefficient of the region, based on the average annual temperature and duration of the season.

The time for consideration of the application in this instance can be a week. After that, the technical conditions for the development of the project are given out on hand. Next, it will be necessary to correctly design the connection scheme, according to the received data. It can not be done on your own. Project documentation is carried out by organizations that have a license for this type of activity. After the project is drawn up, it will be necessary to collect an additional list of papers relating directly to the equipment: conformity assessment, technical passport, certificate, instruction. All the received package of documents is taken to the gas supply organization for approval. The process can last from one week to three months, depending on the season and complexity of the facility. After obtaining permission, you can proceed with installation. If the refusal is received, then the reason will be prescribed in it. It will be necessary to finalize the project and reconcile.

Specifications for connection

A household floor gas boiler can only be installed by an organization and its employee who is licensed to carry out such activities. Itself in no case it can not be done. To install the heater, the following technical conditions must be observed :

• There should be free access to the device at any time.
• The size of the opening in the boiler room is not less than 800 mm.
• The area of the boiler house is not less than four square meters.
• The height of the ceiling is at least two and a half meters.
• Required water supply to the room.
• The walls and floor must be covered with non-combustible materials: tiles, plaster.
• Mandatory installation of a chimney of the required diameter.
• If the heater will work with electricity connection, then the socket must be arranged with grounding.
• It is necessary to have an opening window that will serve in necessary situations, as a source of light and exhaust.
• The floor must be flat.
• Presence of supply and exhaust ventilation.

Do not install gas equipment in rooms without ventilation, dormitory rooms, as well as in bathrooms, corridors, basements, balconies and basement floors. The equipment should not stand close to walls lined with combustible materials. As you can see, floor gas heating boilers require rather harsh conditions for their connection. But, having fulfilled 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 must be mounted and connected by specialists licensed for this type of activity. Most often, workers of the gas supply organization do this, but they are related to the service department. The same unit will then be responsible for the maintenance of the unit.

Heating wiring around the house, installation of the boiler can be done by yourself. But the connection and connection must be carried out only by a licensed specialist. This condition is mandatory. Otherwise, the connection will be considered illegal and dangerous for others. Installation master does based on the scheme and the passport for the equipment. Also touches the chimney. It must necessarily pass a survey and a test for fire safety. Installation of the system should be carried out at a temperature mode from +5 to +35 degrees Celsius. In order to ensure the safe use of gas heating, the operating instruction must be followed. It is worth noting a number of common points:

• Before using the equipment for the first time, it is necessary to check the tightness of the pipes. You can do this by spreading with a soap solution of the joint site. If bubbles appear, disconnect the gas supply, ventilate the room and eliminate leakage.
• Do not expose the unit to mechanical stress. The body of the gas equipment is not designed for strikes.
• In the event of an odor of gas during operation, call emergency service. Do not try to eliminate the breakdown by yourself.

Types of boilers

This type of equipment is considered very reliable. He has a high heat recovery rate of 90-93%. Outdoor gas heating boilers have gained popularity due to high efficiency, the ability to heat areas from 100 to 800 square meters. M. A wide range of models allows you to choose the device that will meet the technical needs and financial capabilities of the buyer. The configuration of such devices can be different: from the simplest to the most automated. For areas where there are voltage surges, you can use the device without connecting to the network, which will save on further use. Usually the devices are sold together with thermal sensors, which, when the required temperature is set, translates the device into an economical mode of operation. For this type of heater is characterized by two types of material for the device heat exchanger:

• Cast-iron. This raw material is not subject to corrosion. Practically ruled out. Such a heat exchanger can serve up to fifty years. But he is afraid of strong mechanical effects and a sharp temperature drop.
• Steel. Resistant to cracking and deformation. But are prone to corrosion and burnout. Pros - it's light weight products, inexpensive price. The life of such a heat exchanger varies from 5 to 15 years.

Until now, there can be devices with copper heat exchangers. But this material is expensive and at the same time prone to burnout.

There is one more classification. On the combustion chamber, the apparatus can be:

1. Open type. In this form, the oxygen for combustion is taken from the room, and the combustion products exit through the chimney.
2. Closed type. For such an option, the chimney device, supply and exhaust ventilation is not required. Because the unit does not tighten the air from the room, and the equipment includes a smoke removal system.

By type of burner, there are atmospheric and inflatable boilers. The first work less noisy. Are of low price. The burner is usually included in the apparatus. In the second, air is forced by a fan, so a higher noise level. Required connection to the mains. Most often sold separately from heating equipment. The cost is considerable.

Installation of heating devices depends on the type of fluid circulation in the system. It is forced and natural. In the first case, it is necessary to connect to the mains. There is an increased circulation rate, which allows you to better heat the room. In the second case, you will encounter quite a complicated installation. But you can connect to the simplest mechanical boilers. For proper operation during installation, a certain slope of the pipeline must be observed. As for floor types of equipment, it can be divided into two large groups: one-circuit and two-circuit.

Boiler gas single-circuit outdoor

This type of heating units is one of the most popular. Consider its advantages:

• Economical. The cost of this option is much lower than the analogs - no more than 20 thousand rubles. And if you choose a Russian floor gas boiler, the price will surprise you even more. At the same time, the quality will be at the proper level. Do not forget about maintenance. Repair of the domestic unit will cost significantly less.
• Simple design, easy to maintain. Easy to operate.
• Can heal large areas.
• Economical gas consumption.

A single-circuit gas 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 drawbacks include the fact that for a hot water system you have to buy a separate system of water heating.

So, we want to buy an outdoor gas boiler. Which to choose? Reviews recommend this device to buy in homes and apartments that have central hot water supply. Below we consider two-loop systems.

Boiler gas double circuit outdoor

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

• The opportunity not only to heat the premises, but also to heat water for household needs regardless of the season.
• High heat dissipation.
• A wide range of models, complete with automation.
• Possibility of installation of additional systems of regulation of temperature modes in various premises.
• With automated systems, safety in operation increases several times. If a failure is detected, the system may stop the operation of the device.
• Reliability due to self-diagnosis.

It should be understood that when the choice falls on the boiler gas double circuit outdoor, the price will depend on the number of automation and additional functions. The same can be attributed to the main shortcomings:

1. Dependence on electricity. In the event of a power outage, the heating system will also not work, which in regions with low temperatures in winter will be critical. Such devices are not advised 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 boiler gas floor, the price and technical data will play a major role. Consider the following factors when considering models:

• Heater capacity. An important indicator. Typically, for single-circuit boilers, the heating capacity is set. And for two-circuit ones, one should also take into account the expected water flow. If the calculation is incorrect, the second option can produce a deplorable result in the form of weak heating. It is recommended to lay a stock for this type of equipment.
• Fuel consumption. It also affects the efficiency of equipment. Depending on the flow and power, you should choose the best option to minimize operating costs, but to get quality heating.
• The material from which the heat exchanger is made. As previously stated, the gas boiler, cast iron floor, with proper operation, will last at least twice as long as the apparatus with a steel heat exchanger.
• Automation. The smarter the heating system, the safer. It is not recommended installation in areas where there are interruptions to electricity or sudden voltage drops. 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.
• Kind 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 area of heating is up to 200 sq. M. M.
• Manufacturer. Undoubtedly, domestic equipment will cost significantly less. And in addition to this, you can get a quick and cheaper repair in case of a breakdown. For importers, a longer service life is characteristic, minimizing breakdowns when properly used
• Consumed electric power. This indicator indicates that you will need to connect to the electrical network. And on its size depends additional costs in operation.
• The possibility of regulating the temperature regime. It should be noted that a number of the simplest boilers also have this function. This changes the temperature of the water heating. In automated systems, it is possible to install a temperature sensor in the rooms, with which the apparatus itself will regulate the supply of gas.
• 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 the heating system choose a gas-fired boiler? The price of gas, as fuel, remains the most attractive. Plus, add the durability of the equipment with proper operation and ease of maintenance. In the event of a breakdown of old equipment to an existing system, you can easily connect a new device. Separately, it can be noted that the market offers a wide range of outdoor gas equipment, which at a different price range has a decent quality. One such device is the Czech floor-standing gas boiler "Proterm".

Which manufacturer's equipment to choose?

If we consider domestic producers, then, unfortunately, the quality is still inferior to imported options. However, do not forget that the price remains low. But later, more frequent repairs may be required. And in the long run, the service life is lower than the declared one. Among other things, the domestic producer 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 ground gas boiler "Proterm" is produced in several modifications. In the context of the types of floor units, there are economical options. Also there are also the most automated devices. One of the most popular systems of this type are the floor gas boilers "Medved". The manufacturer has a fairly wide range of quality equipment. The equipment is different. The power can be selected exactly as it is required. The heat exchanger is made of quality cast iron. In addition, there are various options for automation. Based on their needs, you can choose exactly the model that is most suitable. The price varies from 40 to 140 thousand rubles.
