Which is better to choose a floor gas boiler. Advantages and disadvantages of wall-mounted boilers. Types of floor structures
The heating system in a residential building is of great importance, since comfort, comfortable living and durability of the building structure depend on it. Currently, to install a heating system in the private sector, most often experts advise choosing floor gas boilers heating. They have positive characteristics in the construction market, are popular among customers, are distinguished by their reliability, in addition, floor gas boilers are economical and easy to use.
Gas is the main fuel that provides space heating with a heating boiler. They are installed on the floor, do not take up much space and do not spoil the overall design of the room. A review of Internet forums once again proves that floor-standing gas boilers have a large number of positive reviews and positive characteristics when used.
General characteristics of floor gas heating boilers
Floor gas heating boilers have their own design features. Distinguish single-circuit boilers heating and double-circuit. Their difference lies in the fact that the single-circuit is responsible exclusively for heating the room, and the double-circuit performs the function of heating the room and heating cold water.
It looks like a boiler connected to the heating system.
The double circuit has the best qualities and is more functional and convenient for modern life.
Dual circuit floor standing boilers heating systems are reliable, durable, distinguished by their practicality and a high degree of safety in use. It also confirms the fact that such heating boilers are very economical and are able to rationally consume the main fuel. Double-circuit household gas boilers provide two functions at once: high-quality space heating, constant availability of hot water in the house.
Manufacturers guarantee the safety of double-circuit floor gas boilers, as a special combustion sensor is built into the design. If the flame suddenly goes out, then the sensor immediately triggers and blocks the gas supply. Thus, gas leakage is not terrible. Manufacturers took care not only of hot, but also clean water. The boiler is equipped with special filters that purify the water. Also, popularity is associated with the presence of the function of cleaning the combustion chamber.
Varieties of floor gas heating boilers
Floor boilers gained their popularity many years ago, and this is due to the ease of installation work and ease of use. Such a boiler is practical and reliable if it is intended to heat a large area of \u200b\u200bthe room.
As for single-circuit gas boilers, they are suitable for you if you want to provide one main function indoors - heating. Single-circuit floor gas boilers are compact and inexpensive. But in order to ensure the availability of hot water in the house, you will have to buy a special boiler to heat water.
The principle of operation of double-circuit is that gas is supplied to a special closed chamber of the heating boiler. Inside this chamber, the combustion process takes place and heat is released. Thanks to heat exchange, floor-standing gas boilers are able to heat water in a boiler or other tank.
There is also a variety of floor gas boilers that work with materials such as sawdust, firewood, coal or peat. They are called solid fuel, as they work on solid fuel. Standard floor heating boilers are made of cast iron, have a lot of weight, but are distinguished by their reliability and durability. They have an anti-corrosion effect, but are quite sensitive to shock and damage. This material can quickly crack or burst. Therefore, cast iron boilers require careful handling.
In modern times, there is a variety of analogues of heating boilers, which are made of other, less heavy, but no less high-quality materials. For example, currently popular are heating boilers made from heavy gauge steel. Such boilers are quite light, which ensures ease of transportation and installation. They are shockproof, resistant to hypothermia and overheating. The only drawback of such a material is that steel can burn through over time.
The distinctive characteristics of outdoor gas boilers do not end there. There are many types of boilers in terms of external indicators and functional properties. You can choose a boiler that will perfectly suit the design of your room in size, appearance and decorative features.

Requirements when choosing floor gas boilers
When choosing a heating boiler, it is important to pay attention not only to the external indicators and functionality of the structure, but also to the internal structure and serviceability of all parts of floor-standing gas boilers. When choosing, pay attention to the condition gas burner, on the capabilities and power of the unit, as well as consult with specialists regarding the features of installing a floor-standing boiler. Try to correctly calculate the power of the heater so that it can heat the entire area of \u200b\u200bthe living space.
The main advantage of floor gas boilers is that they are able to generate the maximum amount of heat with minimal energy consumption. Automatic ignition ensures economical operation heating structure and ensures optimal combustion of heat.
Floor gas boilers are considered more efficient than mounted models. This is due to the fact that the outdoor ones have great endurance and high functionality. They are able to cope with heavy loads and efficiently heat a large area of \u200b\u200bthe room.
When choosing floor standing boilers, it is important to consider the safety side of the equipment. All parts must be in good condition, the boiler must perform all its functions and work without interruption. The operation of the underfloor heating boiler must not endanger environment, human health and life.

- provide long, uninterrupted operation;
- are characterized by ease of maintenance and ease of repair work;
- have a built-in diagnostic system that determines the cause and degree of equipment failure;
- work almost silently;
- have affordable price and long service life.
Among the huge variety of modern heating equipment, floor gas boilers are still not inferior to them in their popularity. The technology of their work is time-tested. Therefore, if you decide to provide your home with heat, want to be sure of its reliability and rationally spend the family budget on heat supply at home, we recommend that you opt for a floor-standing gas boiler.
Updated:
2016-09-04Today, floor heating boilers are increasingly being chosen to heat the house. The range is replenished every year with models with new features. To choose a suitable boiler, it is important to understand the types of floor boilers and their features.
Floor heating equipment is selected when it is possible to allocate a separate room for it. Having large dimensions, the floor boiler has great power.
Advantages of floor boilers:
- High efficiency.
- Simplicity of design. The device of modern boilers is fundamentally no different from older models. Simplicity ensures greater operational reliability.
- Possibility of simultaneous heating and heating of running water.
At the same time, outdoor equipment has a number of disadvantages:
- Large dimensions. To install a floor boiler, you will need a separate well-ventilated room.
- A chimney is a must. During the combustion of any fuel, combustion products are released, which must be removed from the room.
Despite all the disadvantages, now floor-standing boilers occupy a leading position as equipment for heating and creating hot water.
Fuel types
Depending on the availability and price, a floor-standing boiler is selected that runs on the desired fuel. The energy carrier can be gas, electricity, liquid and solid fuel. There are also combined models that can use several types of fuel for heating at the same time.
Gas floor boilers are the most common due to the low price of gas. They have one of the highest efficiency, approaching 100%. Suitable if there is access to a gas pipeline. Like any gas equipment must be installed by experts.
Solid fuel boilers mainly use coal, firewood, compressed sawdust and wood chips. They do not depend on electricity and the presence of a gas pipeline. The disadvantages are the need to store fuel supplies and the impossibility of full automation. Control and regular addition of energy carrier is required.
Electric floor standing boilers are easy to maintain and safe. Not widely used due to high electricity prices. The cost of heating with electric models is higher.
Liquid fuel boilers can replace gas boilers in the absence of a gas pipeline nearby. Models are high power, require permission to install. The downsides are high fuel prices and the need for storage facilities.
The combined type of boilers runs on several types of fuel. This allows you to choose the type of fuel depending on price and availability. Such a boiler is much more expensive than analogues and is used for heating industrial facilities.
Need for electricity
Also, all models are divided into volatile and non-volatile. The former require an electrical connection to operate. automated systems. Such a boiler works autonomously and does not require constant monitoring. Also, such systems are usually equipped with additional equipment: temperature controllers, electric pumps for water circulation.
Non-volatile models do not have such automation. Their device is maximally simplified. Require regular monitoring, but continue to work in the event of a power outage.
Also, some modern models are equipped with a heat generator that generates electricity from heat. This allows you to combine automaticity and independence from the network.
Heat exchanger material
The main materials for the manufacture of heat exchangers are cast iron, steel and copper. Each configuration has its own characteristics.
Floor boilers with cast iron heat exchangers are considered the most durable. They have a service life of 30-50 years. They do not burn out due to thick walls and do not rust. The main disadvantage is fragility. Due to its high hardness, cast iron is afraid of impacts. Cracks may appear during transportation or sudden temperature changes.
Steel heat exchangers are lighter and more impact resistant. But they have half the service life compared to cast iron models. Burn out faster and corrode faster.
Copper heat exchangers last longer than steel ones, but are used only in boilers with a power of up to 50 kW.
Types of combustion chambers
In some cases, the type of combustion chamber may be the determining factor. There are two types:
- Open combustion chamber. The air from the room is used for combustion. The place where the equipment is located must be well ventilated. They work almost silently. It is undesirable to install the boiler near furniture or gas meters, as their body becomes very hot.
- Closed combustion chamber. Equipped with a fan that supplies air from the street and supplies combustion products back. It has a high efficiency, but requires the connection of electricity to the fan. The case of such models is not heated. The price of such a burner is higher.
Single and double circuit boilers
The main purpose of a single-circuit boiler is to provide space heating. It does not have a system for heating running water. Therefore, if warm water is required in the room, it will be necessary to install separate equipment for this. Such a floor boiler has less power and lower cost.
Provides space heating and heats running water. Allows you to save on the purchase of a boiler. Heating is a priority. If there are many people living in the house, it may not provide enough hot water. The cost and dimensions of such boilers are higher.
A variety of floor boilers allows you to choose the best option for each room. Having determined your needs and sorted out the types of models, you can choose equipment that will allow you to economically and efficiently heat your home.
When it comes to installing a heating system, there are always a few questions. One of them - which boiler is better to choose? If the choice falls specifically on the gas boiler, then other questions arise - where to fix it - to the wall or to the floor? Should it be single or dual circuit? Maybe you should choose a regular one or opt for a condensing one?
One or two contours: features of choice (video)
Typically, a gas boiler is chosen in cases where there is a connection to a natural gas supply source. Such a boiler is quite economical in operation and at the same time automated.
The first question to consider is whether to choose a single or double-circuit boiler?
The difference between these two types of boilers is the presence or absence of a heat exchanger. This element is responsible for heating water not only for the heating system, but also for hot water supply. The heat exchanger is present only in a double-circuit boiler. In a single-circuit one, it is not, which means that it is only capable of being responsible for the heating system.
If you use a single-circuit boiler for hot, you must use the boiler. It will require the purchase of additional nodes. If the single-circuit boiler is floor-standing, you will need to purchase expansion tank, safety valve and circulation pump. This, in turn, means that you will have to find an additional place to install all this equipment.
As a result, this whole structure takes up a lot of space and requires a separate room. You can purchase a boiler with a built-in boiler - this will at least allow you to place it on. In any case, there is much more fuss when installing this boiler than with a double-circuit one.
Compared to its bulky counterpart, the double-circuit boiler is simply the epitome of elegance - this small cabinet with built-in additional equipment takes up much less space, located on the wall.
Best of all, a double-circuit boiler is arranged where the closest point to the place of water intake is located. Ideal Location important elements while it looks like this: it is located next to the kitchen, and only one person takes the water. Thus, water will reach the tap faster, and its consumption will decrease significantly.
In the event that the bath is still far from the kitchen, it is recommended to install the boiler in the kitchen, since hot water still more often taken there. In this case, hot water in the tap will not have to wait too long. But if the distance between the mixer and the boiler exceeds seven meters, you have to wait a good while. Often in the case when the house has two or more bathrooms, an additional boiler is installed to provide the house hot water in abundance.
By price double-circuit boilers are cheaper than single-circuit complete with a boiler.
On the wall or on the floor?
Most often, the boiler provides heat and hot water to one family, and therefore is small in size and can be mounted on the wall. This does not apply to the case when a boiler is built into the boiler, the boiler itself is large enough in volume and has a power of more than 30 kW. On sale you can also see small floor boilers.
Floor boilers are units with built-in additional equipment including a boiler. It is clear that if a boiler with a capacity of over a hundred liters, and the boiler itself is large in all respects, then you cannot hang it on the wall. But all the elements are hidden by a single body, which makes this unit quite attractive in terms of design. It can be installed not only in the house, but also in the workshop or pantry.
Another type of floor-standing boilers - without a boiler, have a cast-iron heat exchanger, which is larger and much heavier than a metal one. Due to this, the weight of the product is significantly increased, but the boiler also lasts longer. The design of such a heat exchanger provides for the placement of the boiler in houses with an old type of heating, when it is planned to replace an outdated boiler with a new, more reliable one. The design itself involves embedding such boilers in the old system heating.
If you have a small apartment or house, a wall-mounted double-circuit boiler is perfect. Given that it contains all the necessary elements, including a flow heater, it takes up little space and at the same time successfully supplies hot water with heat, saving space.
If you have a separate area for the boiler, you can purchase a wall-mounted boiler along with a large boiler or a boiler with a capacity of less than 100 liters, which can be hung on the wall.
Boilers with a boiler capacity of less than 100 liters can themselves be made as wall-mounted.
Condensing boiler or conventional boiler?
Ordinary boilers are distinguished by a favorable price, but unprofitable energy consumption, a tenth of which flies into the chimney. Condensation does not allow her to do this, cooling gases and steam and using this so-called latent heat.
As a result, it is by this tenth that condensing boilers are more useful than conventional boilers, and the same indicator is present in fuel economy. True, you have to pay a higher price for such equipment for this.
It makes sense to think - economical fuel consumption will allow you to win back the difference in price when buying a condensing boiler for some time.
Maintenance
The gas boiler itself is undemanding to maintenance, therefore, during the entire heating season man does not interfere with his work. But before the start of the next heating season, the boiler must be checked - the chimney must be cleaned and the combustion products removal system must be checked. All systems must function properly.
How to regulate work?
On sale you can find devices that greatly simplify the use of the boiler. One of them is a mechanical thermostat acting as a temperature regulator. You set the temperature value for the heat carrier, and if the temperature of the carrier starts to decrease and falls below the set mark, the thermostat turns on the boiler burner. If the value is exceeded, automatic shutdown follows.
Everything these days more people have their own homes, where you can relax from the hustle and bustle of cities. The desire to visit a suburban building arises not only in the warm season, so the residents of houses think about maintaining comfortable living conditions.
The best solution for heating a suburban building is the installation of a gas boiler.
Advantages and disadvantages of floor boilers
Designs of this type are endowed with a large number of positive characteristics:
- The system has high efficiency;
- Despite the low cost, the units are very high quality;
- Ease of care and use;
- Boilers are able to maintain the required temperature even in houses with a large area. Manufacturers offer a large number of models with different capacities.
In the photo: the functioning of the floor heating boiler.
Like most heating appliances, gas boilers have several shortcomings:
- Floor-standing units require a special installation permit, which not everyone can get;
- It is recommended to install the structure in a room with a separate exit from the house.
Classification of gas-fired boilers
All floor installations can be divided into two types.
1. Boilers using atmospheric burner. This type of heating structure is considered more economical and simple, moreover, during the operation of the boiler, the noise level is minimized. The power of the units can reach 156 kW.
The peculiarity of these boilers is that the air used for reactionary combustion is unaided to the burner. In most cases, this type of device, where the burner is built into the boiler itself, is used in devices with an open combustion chamber.
2. Boilers with built-in burners of two different types: supercharged or fan. These parts are used in equipment that has a closed combustion chamber.
Air mixed with gas is forced by a fan. This method of supply involves the combustion of fuel to the end. Due to the fact that the level of efficiency of such boilers is quite high, their price is high, which means that such designs are unprofitable for suburban buildings.
Functionality of floor boilers
Gas boilers installed in private homes are divided into two types:
- single-circuit, which consist of one circuit. It is in it that the process of heating the coolant takes place. A boiler of this type does not supply the water necessary for technical needs, therefore, when installing this model, a boiler will be required. Despite the fact that the boiler is convenient to use, it consumes too much electricity, so it becomes unprofitable. In case of uselessness, it is recommended to turn off the equipment, since over time the water will evaporate, and sediment will appear inside the tank. It can adversely affect the water, giving the liquid an unpleasant odor.
In the photo: the principle of operation of a floor-standing gas heating boiler.
- have two heat exchangers, one of which is designed to heat the water entering the heating system, and the second for the liquid used in household chores. It is necessary to monitor the carbonate hardness, since it elevated level can cause scale build-up in the heat exchanger. To avoid damage to the boiler, it is recommended to regularly remove scale and clean the coil. The cleaning process requires special skills, so you should prepare before starting work.
Manufacturers of heat exchangers offer several design options made from different materials.
- Steel. The equipment is made in the form of a cylinder. It consists of a large number of pipes having a small diameter and responsible for the conductivity of water. By weight, the unit is not too massive, and it is also protected from mechanical stress that may occur during transportation.
- Cast iron. This material is heavy, resistant to damage, but serves for a long time.
Distribution of boilers by type of ignition
Gas installations are divided into two groups according to the ignition method:
- Electronic
- Ignited by piezoelectric elements.
In the first case, the boiler igniter works only when the thermostat needs to be turned on, so such units are more profitable and economical.
In the second case, the burner is ignited by a piezoelectric element, which starts working after turning a special lever or pressing a button. The biggest advantage of these structures is their independence from, that is, the boiler distributes heat regardless of the availability of electricity in the house. Such units consume fuel for a whole day, and although the costs are small, they are not justified, since only 1/4 of the total volume is required to maintain combustion.
Types of floor structures
In suburban buildings, two types of gas units are used:
Convection
There is a concept of two points of calorific value: lower (denoting thermal energy, formed during the combustion of gas in full) and the highest (indicates the total energy obtained during the complete combustion of gas and condensation of combustion products).
When designing gas boilers, manufacturers make every effort to minimize condensation in the heat exchanger. Thus, the boilers are protected from the formation of sediment, which can form in the presence of aggressive acids. Unpleasant consequences can render all equipment unusable.
The whole principle of operation of this type of boiler is based on the absence of condensate in the fuel part. This effect is achieved by installing classically shaped radiators. The length of the heating circuit and the heat treatment, which must be large, must also be taken into account. Compliance with all rules guarantees the absence of condensate on the heat exchanger.
Condensation
They have a built-in economizer responsible for cooling. The temperature during this process contributes to the formation of moisture. Due to this, the liquid is heated before entering the heat exchanger.
In the photo: a condensing gas boiler.
Gas boiler installation technology
Installation of equipment is not the easiest work, therefore, it requires compliance with the rules and regulations:
- Depending on the power of the installed equipment, the area of the room in which the boiler will be located must be calculated. The minimum room size can be 4 square meters.
- In the room intended for equipment, the presence of a doorway (at least 80 cm) and a window is required.
- The boiler is installed on a concrete floor.
- There must be a distance between the gas appliance and the enclosing parts (minimum 0.3 m).
- also worth paying attention to. They need to be finished with materials that do not burn or with steel sheets.
- The pipe designed to remove smoke should be half a meter higher than the roof ridge.
- The inner diameter of the chimney pipe must be larger than the outlet of the equipment.
- The chimney is made in the form of a cylinder of steel, protected from rust. You should also monitor the number of pipe bends. If there are more than three turns, then this will negatively affect traction.
- To prevent mechanical impurities from entering the liquid, it is recommended to install a coarse filter on the pipe supplying cold water.
- A coolant supply pipe is installed on top of the boiler, processing is installed on the bottom.
- The boiler shut-off valves must be installed without fail.
- The boiler may only be connected with metal pipes.
- All connection and start-up work must be carried out by a professional.
- Using soapy water, check all connections. When depressurized, bubbles will appear on the surface.
- Air must be bled from each radiator. To do this, open all.

Conclusion
Nowadays, construction markets are overflowing with various models of gas boilers. On sale there is domestic and foreign equipment that does not have big differences. Regardless of what choice was made, it is worth considering all the rules of installation and operation. Having done everything right, you can be sure of a long service life and reliability of the boiler.
