Overview of modern gas floor heating boilers, analysis of the main characteristics and manufacturers

Currently, gas remains the most optimal energy source for creating an efficient and reliable heating system. Along with wall-mounted boilers, floor-standing models are used to complete the heat supply. They have a number of specific features that should be taken into account when creating a circuit and installing. Consider the main parameters that floor gas boilers have for heating a house, a review of manufacturers and reviews.

Selection and operation of gas floor boilers

How to determine the best floor standing gas heating boilers? First of all, you should pay attention to their rated power, configuration and manufacturer. Household heating must be not only efficient, but also reliable.

It should be noted that domestic floor-standing gas heating boilers are currently almost in no way inferior to foreign counterparts.

Therefore, the choice is mainly determined by the functionality of the equipment and technical characteristics. All gas heating boilers operate on the principle of transferring thermal energy from fuel combustion to a coolant.

However, in practice, the value of efficiency and reliability of operation is determined by the following parameters:

• Burner type... Foreign and Russian floor-standing gas heating boilers can be equipped with a single-stage, two-stage or modular burner. It is preferable to choose the latter option - the flame intensity is adjusted with great accuracy;
• Rated power. This parameter directly depends on the characteristics of the building: its heat losses, the number of window and door structures;
• The cost... The most expensive are cast-iron gas-fired floor heating boilers, since this material of manufacture is best suited for the manufacture of the body and the heat exchanger.

An important role in proper operation is played by the organization of the equipment installation site. So, floor-standing double-circuit gas heating boilers must be connected not only to heat supply lines, but also to hot water pipes. Conditions for the premises and equipment can be obtained from the Management Company. Upon request for the installation of gas equipment, it is obliged to issue complete Technical Conditions. Only then is the gas floor boiler connected to the heating system.

To save money and in the presence of a solid fuel boiler, you can make its modification by installing a gas burner. It is important that the heat exchanger is designed for an increased temperature level and that the chimney provides the required draft level.

Types of heat exchangers in gas floor boilers

One of the defining parameters for boilers is the material of the heat exchanger. Many Russian and Ukrainian floor-standing gas heating boilers are equipped with steel heat exchangers. But to increase the service life and improve technical characteristics, it is recommended to choose cast iron models.

For cast-iron gas floor heating boilers, a long service life is characteristic.They are less susceptible to the appearance of rust and scale on the inner surface of the walls. However, along with this, it is necessary to take into account an important disadvantage of a cast-iron heat exchanger - a large mass and dimensions. As a result, this affects the size of the boiler.

It is because of this that cast-iron components are rarely included in the package of floor-standing double-circuit gas heating boilers. The problem lies not in the complexity of manufacturing a double heat exchanger, but in its weight and dimensions. In addition, the consumer should know the following distinctive properties of Russian floor-standing gas heating boilers with a cast-iron heat exchanger:

• Damage susceptibility to severe impacts... Cast iron has practically no ductility. Therefore, with mechanical stress, the likelihood of cracks and chips is high;
• A sharp drop in temperature negatively affects... This is relevant in those heat supply systems where a change in the flow of the coolant is possible. Overheating of the case or a sharp change in water temperature will cause loss of tightness;
• High heat capacity... After connecting the gas floor boiler to the heating system, heating of the coolant will be slower than that of a steel heat exchanger. But on the other hand, after turning off the gas heater, the water will heat up for some time.

In most cases, non-volatile gas floor heating boilers are equipped with steel heat exchangers. This type of appliance does not require an electrical connection. The burner is ignited by a piezoelectric element. In this case, the choice of a steel heat exchanger is dictated by its relative cheapness and lower weight. However, the service life of such models is 10-15 years.

In the best floor-standing gas heating boilers, the heat exchanger is made of copper. This is the optimal material, but it is much more expensive than cast iron or steel. Therefore, such models are less and less common.

Types of gas floor boilers

To select the optimal model of Ukrainian gas floor heating boilers or manufacturers from other countries, you should pay attention to the technical data of the equipment. One of them is the rated power of the boiler.

The optimal power for a specific heating system is determined by complex calculations. The heat losses of the house, the climatic features of the region, the recommended thermal mode of operation of the equipment are taken into account.

For foreign or domestic floor-standing gas heating boilers, the power should not be lower than the calculated one. Experts recommend purchasing a model with a small margin of 10-15%. If it is higher, fuel consumption will increase, which will affect the efficiency of the entire system.

Regardless of the choice of floor-standing cast-iron gas heating boilers or their steel counterparts, a number of factors must be taken into account:

• Number of contours... If there is no need to provide hot water supply, you can choose a single-circuit model. For hot water supply, you should purchase a double-circuit floor-standing gas heating boiler;
• Atmospheric or closed burner... In the first case, air is supplied from the room to maintain the combustion process. But to reduce the likelihood of combustion products entering living rooms, it is recommended to purchase models with a closed burner. A coaxial chimney is installed for them;
• The ability to adjust the intensity of the flame... Modular burners have the best efficiency indicators. But they are very expensive. To supply heat to a small house or summer cottage, you can connect a gas floor boiler with a two-stage burner to the heating system;
• Electrical connection. There are a number of non-volatile gas floor heating boilers that do not need electricity. However, their performance is slightly lower than that of electric models. This is due to the lack of electronic control components.

In the overwhelming majority of cases, domestic floor-standing gas boilers for heat supply are technically no different from their foreign counterparts. Therefore, with the same operational qualities, floor-standing gas heating boilers of Russian or Ukrainian production are most often chosen.

Before purchasing a floor-standing non-volatile gas heating boiler, you should inquire about the availability of service centers for its maintenance. This information will come in handy in the event of equipment breakdown or for informational assistance.

Reviews of floor-standing gas boilers

One of the ways to choose the best floor-standing gas boilers for heating your home is to study customer reviews in detail. But at the same time, you need to pay attention to their subjectivity, since often information about a failure in the operation of the survey does not include violations of the rules of operation and installation.

• Last year we purchased a floor-standing gas boiler from the Conord company. Attracted by the low cost, the ability to independently connect to cylinder heating. During the first month of operation, we had to adjust the boiler ourselves to set the temperature regime. Although the best thing was to call specialists. We are satisfied with the work of the boiler;
• After a long analysis, we decided to buy a Lemarks gas boiler for our house. The reason for the choice is that the neighbor has the same. We settled on a model with Italian automatics. Sometimes there are problems with switching on under reduced gas pressure. The rest of the boiler works more than well;
• We bought an expensive Protherm boiler with hot water supply and a modular burner. After a month of work, the control unit failed. After calling the service center, a specialist came and made a replacement. It is a pity that during this time (winter and frost) pipes froze in some places in the house.

The choice of the best gas floor boiler is influenced by its cost, power density and equipment. Also, do not forget the possibility of prompt repair and maintenance. Therefore, first of all, it is necessary to pay attention to the network of service centers from the manufacturer's company.
