Currently, gas remains the most optimal energy source for creating an efficient and reliable heating system. Along with wall-mounted boilers, floor models are used to complete the heat supply. They have a number of specific features that should be considered when creating the circuit and installation. Consider the main parameters that floor gas boilers for home heating have, manufacturers reviews and reviews.
Selection and operation of gas floor boilers
How to determine the best floor gas heating boilers? First of all, you should pay attention to their rated power, equipment and manufacturer. The heat supply at home should be not only effective, but also reliable.
It should be noted that domestic floor-standing gas heating boilers are currently practically inferior to their 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 the combustion of fuel to the coolant.
However, in practice, the value of efficiency and reliability is determined by the following parameters:
- Burner type. Foreign and Russian gas floor heating boilers can be equipped with a single-stage, two-stage or modular burner. It is preferable to choose the last option - the flame intensity is adjusted with great accuracy;
- Rated power. This parameter directly depends on the characteristics of the building: its heat loss, the number of window and door structures;
- Cost. The most expensive are the cast-iron gas heating boilers floor, as this material is best suited for the manufacture of the housing and heat exchanger.
An important role in the proper operation is played by the organization of the equipment installation site. So, floor-mounted double-circuit gas heating boilers must be connected not only to the heating mains, but also to the hot water pipes. Conditions for premises and equipment can be obtained from the Management Company. Upon request for the installation of gas equipment, it is obliged to issue full 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 elevated temperature level, and the chimney ensures the required draft level.
Types of heat exchangers in gas floor boilers
One of the defining parameters for boilers is the material of manufacture of the heat exchanger. Many Russian and Ukrainian gas floor heating boilers are equipped with steel heat exchangers. But to increase the service life and improve the 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 prone to rust and scale on the inner surface of the walls. However, along with this, it is necessary to take into account the important drawback of the cast-iron heat exchanger - its 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-mounted double-circuit gas heating boilers. The problem lies not in the complexity of manufacturing a double heat exchanger, but in its mass and dimensions. In addition, the consumer should know the following distinctive properties of Russian gas floor heating boilers with a cast-iron heat exchanger:
- Strong impact damage. Cast iron has virtually no ductility. Therefore, under mechanical action, the likelihood of cracks and chips;
- A sharp change 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 a loss of tightness;
- High heat capacity. After connecting the gas floor boiler to the heating system, heating of the heat carrier will be slower than that of a steel heat exchanger. But then, after turning off the gas heating pad, the water will heat up for some time.
In most cases, non-volatile gas floor heating boilers are equipped with steel heat exchangers. For this type of devices, you do not need to be connected to the mains. The ignition of the burner occurs due to the piezoelectric element. In this case, the choice of a steel heat exchanger is determined by its relative cheapness and lower mass. However, the service life of such models is 10-15 years.
At the best floor gas heating boilers, the heat exchanger is made of copper. This is an optimal material, but it is much more expensive than cast iron or steel. Therefore, such models are found less and less.
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 optimum power for a particular heating system is determined by complex calculations. The heat losses of the house, the climatic features of the region, the recommended thermal regime of the equipment are taken into account.
For foreign or domestic floor 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 larger, 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 circuits. If there is no need to provide hot water - you can choose a single-circuit model. For domestic hot water, a dual-circuit floor gas heating boiler should be purchased;
- 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 the living room, it is recommended to purchase models with a closed burner. For them, a coaxial chimney is installed;
- Ability to adjust flame intensity. Modular burners have the best economy. But they are notable for their high cost. For heating a small house or 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 vast majority of cases, domestic floor-standing gas boilers for heat supply are technically no different from their foreign counterparts.Therefore, with the same performance characteristics, gas-fired floor heating boilers of Russian or Ukrainian production are most often chosen.
Before purchasing a floor-mounted non-volatile gas heating boiler, you should find out about the availability of service centers for its maintenance. This information is useful in the event of equipment breakdown or for information assistance.

- Last year, we purchased a floor gas boiler from Conord. Attracted a small cost, the ability to independently connect to cylinder heating. During the first month of operation, we had to set up the boiler ourselves to set the temperature regime. Although it was best to call specialists. Satisfied with the operation of the boiler;
- After a long analysis, we decided to buy a Lemarks gas boiler for our house. The reason for choosing is the same for the neighbor. We settled on models with Italian automation. Sometimes there are problems with switching on under reduced gas pressure. Otherwise, the boiler works more than well;
- We bought an expensive Protherm boiler with hot water and a modular burner. After a month of operation, the control unit failed. After a call, a specialist arrived at the service center and performed a replacement. It is a pity that during this time (winter and frost) in some places in the house pipes froze.
The choice of the best gas floor boiler is affected by its cost, specific power and equipment. Also, do not forget about the possibility of prompt repair and maintenance. Therefore, first of all, you need to pay attention to the network of service centers from the manufacturer.
