Floor gas boiler which to choose

Rating of floor gas boilers 2021: TOP of the best models and which one to choose

The basic function of any boiler is the heating of the coolant (os) for the heating circuit. All models possess it, regardless of what additional capabilities they have.

Best Combi Boilers | Top Five

There are units intended only to prepare the coolant. These are single.Circuit boilers performing the only, main task. In addition, there are dual.Circuit boilers that can simultaneously prepare hot water for household needs.

They are equipped with an additional heat exchanger, which uses part of the excessive thermal energy of the coolant.

These units are called dual.Circuit. They allow you to get the maximum set of functions, but have some performance restrictions on the contour of the hot water.

Heating occurs in proper mode, so it is not possible to achieve uniform and stable temperature yet.

NOTE!Single.Circuit boilers can be connected to external storage boilers. This will require some expenses, but as a result it makes it possible to get a stable and even hot water.

Ideally, the power indicator of the unit should be determined on the basis of thermal imaging, but in practice it is calculated by the average value, based on the calculation of 1 kW for every 10 kV. M area with a margin of up to 20% when choosing a single.Circuit structure. You should not choose a gas boiler with high parameters. A low loading level leads to a decrease in the efficiency and increased wear of the mechanical parts. This category includes equipment suitable for operation in small, up to 100-150 kV. M., houses of residential and non.Residential purposes.

Single-circuit gas boiler S-Term 12.5-inexpensive option for arranging a heating system of a house with an area of ​​100 kV. M. Characterized as absolutely energy.Dependent and effective in terms of fuel consumption. Buyers attribute to him also pluses such as noiselessness and compactness. The boiler efficiency is 90%, which is considered an average indicator for this category of heating equipment.

But the disadvantages of the device are also found, and most often the lower location of the burner is distinguished. In the pallet of the case. However, this does not affect the performance and safety of equipment, although it causes some inconvenience during visual control of the burner. The rest of the equipment can be called an excellent choice for home up to 100 kV. M., Although the manufacturer claims 125 squares. Still, one should not forget about 10-15% of the reserve.

As a result, there are no questions for the work of the boiler and nozzle, I work perfectly in pairs.

Varieties of boilers

It is necessary to carefully approach the choice of equipment, taking into account many factors, such as the area of ​​the room, the presence of thermal insulation and much more. It is better to consult with a specialist in this matter. Floor gas boilers for private houses are presented according to some characteristics:

The presence of contours

Single.Circuit boilers are the most popular among buyers. This is facilitated by a low price, especially the domestic manufacturer. Accordingly, saving funds. Plus everything, the repair of the Russian boiler will cost cheaper. The presence of one circuit suggests that only the coolant will be heated. It follows that the sizes are quite compact and the maintenance is easier. Gas consumption is economical. The only nuance is that in order for hot water to have hot water, you also need to buy a water heater, or an indirect heating tank.

Double.Circuit boilers are certainly more expensive, but technical capabilities are added to the price: first of all, simultaneous heating of water and heating of the room; secondly-most options are equipped with automation. Of course, the presence of automation increases the security system during operation, which is a huge plus. In addition, if a breakdown is found, the system stops the operation of the unit. This speaks of high reliability. If we talk about the disadvantages. The main one is dependence on electricity if the boiler is equipped with automation.

Combustion chambers

With an open.Type chamber, the advantage in natural traction. Oxygen is gained from the room for burning, and combustion products are respectively removed through the chimney. The presence of a correctly built chimney is mandatory! In addition, there should be ventilation in the room. This is also necessary.

A significant disadvantage of such boilers can be called the dependence of the work of the floor boiler on external conditions. The colder the street, the weaker the craving. The weaker the craving, the worse the boiler burns and, accordingly, it directly affects performance.

With a closed camera, everything is simpler. It has a fan that removes the gases and supplies air. In this case, the presence of a chimney is not necessarily. There everything will be done by a supply and exhaust ventilation system. Such a camera increases the efficiency coefficient. Efficiency and lower fuel consumption. Security. Minus. Such boilers are very noisy and electro.Dependent. And they are more expensive.

Heat exchangers

Floor gas boilers for a private house have 3 types of heat exchangers:

floor, boiler, which, choose

Cast iron: absolutely indifferent to corrosion, but the temperature difference is very dangerous for them. They can crack easily. This will lead to repair, and they are very heavy and difficult to replace. But they can last up to 30 years.

Steel: mostly light and very durable, and they are not deformed. Minus. Over time, unfortunately, renders corrosion. They can burn out. From this, their service life, again with proper circulation, is about ten or fifteen years old. At a high temperature of a long fuel time, much larger is consumed.

Copper: small weight, corrosion, fortunately, do not give in. Good thermal conductivity. Only now they are used extremely rarely. Metal expensive and quickly wear out. This option is more often used for low.Power wall boilers.

Type of burner

There are atmospheric boilers and inflatable boilers. Atmospheric work very noisy, but the cost is low. The burner is already in the device. Inflatable boilers of course, due to the presence of a fan, work very noisy. Also depend on the power supply. The cost is high, but it is, accordingly, the configuration.

Using smoke gases

Typically, boilers are designed so that smoke gases, along with water vapors, are immediately allotted outward. Such floor decisions for a private house are called convection. But their temperature is high and heat received at the output can be used again. The condensation units collect steam when the gaseous fuel is combined and as a result the heat obtained is sent to the heating contours. Due to this use of energy, the productivity of both the boiler as a whole and the heating circuit increases. It is fuel saving and an increase in efficiency to 100% and higher. There is only one drawback. High cost. Convection devices are simpler and much cheaper.

floor, boiler, which, choose

It is also important to take into account that condensation boilers effectively manifest themselves only in low.Temperature systems, such as water heating floors. In other cases, they work similarly to a convection unit.

Floor gas boilers rating

Floor gas boilers belong to the category of the most economical devices for heating and hot water supply of country houses or small industrial or agricultural enterprises. Cheap fuel and reliability of technical solutions are complemented by modern technological materials, which displayed floor gas boilers to the first place among all categories of heating equipment.The main problem of choosing the best floor gas boiler is a wide variety of equipment produced, different models of which do not always meet the initial requirements of the owner of a country house or industrial enterprise. The engineers of the Heating Committee have prepared a small rating of the best floor heating devices, which is based on long.Term operation and maintenance of already installed equipment in real conditions of Russian climate and engineering networks.

The floor gas boiler is a stationary heating device, in which the process of heat transfer from the combuster gas to the coolant of the heating circuit is implemented. Structurally, the process of heat transfer occurs in the combustion chamber, inside which there are a gas burner and heat exchanger.The main element of floor models, which determines the reliability and efficiency of the heating system as a whole, is a steel or cast.Iron heat exchanger. Cast iron heat exchangers are highly resistant to corrosion, but require professional heating design. Steel heat exchangers are less whimsical, but their work in low.Temperature modes leads to intensive corrosion of working surfaces.The main difference between flooring devices from their wall analogues is not a complete set of equipment, the list of which often does not include circulation pumps, shut-off and control valves and some automation elements. The necessary list of additional equipment and materials is developed when designing the boiler room, and its composition depends on the parameters of the building and the tasks set.Some tips on choosing a floor boiler

What to consider when buying a gas boiler?

We are sure that after reading this article you can independently decide on the answer to the question, which heating boiler is the best for your home, apartment or cottage. And if you can’t, ask our specialists! We will definitely help you.

When choosing equipment, you need to pay attention to the following points:

The appearance of the equipment, the color of the case is certainly significant. But these are not the main criteria.

Power. In an ideal case, it is believed that with a power of 1 kW, the boiler will heat up 10 kV. M. Paul. But this is true only in relation to houses with high.Quality insulation, standard ceiling height, glazing area. Practices are increased by 25-30%. But you need to be prepared that the price of the boiler will increase;

CHOOSING THE BEST BOILER for us

Temperature adjustment. In the simplest case, the change step is 5-10 0C. Complex projects with exemplary quality allow you to adjust the temperature with an accuracy of 0.1 degrees;

Superfant functions: weather dependent automation, control from a smartphone, inclusion in the “smart home”, etc. D.;

Kkolism of the contours. It is advisable to buy a double.Circuit modification if there is no centralized hot water supply, nor a boiler (electric or indirect heating). But the price of the device with DHW is higher than a single.Circuit. Quality and reliability depend on the technology used by the manufacturer;

Conducting self.Diagnosis. In modern models, the control unit according to incoming signals determines which knot failed: GSU, sensors, heat exchanger, etc. D. The corresponding error code is displayed on the screen and stored in the error log. The service master remains to check the messages and perform the necessary actions as part of the repair or current maintenance.

The calculation of power is better to entrust a specialist-alarm technician. A specific model of a gas boiler (single.Circuit, double.Circuit) is indicated in the project of the heating system. The owner of a house or apartment can express his wishes in terms of value, functionality, double.Circuit or with the installation of a boiler, etc. D. The price of the structure depends on it.

Next, it remains to buy a reliable gas boiler (hinged or floor) and connect it correctly. And with this issue it is also better to contact professionals. Do not forget that for further service it is necessary to conclude an agreement with the local gas service.

Based on all of what the rating said for gas boilers, the rating is compiled by the following principle. First, single.Circuit models are listed, then budget. You can familiarize yourself with information about units with maximum functionality. This paragraph includes both double.Circuit boilers, and without DIS.

What to look for when choosing gas boilers

For the correct choice of heating device, the following characteristics must be taken into account.

  • The power of the boiler is the most important characteristic necessary for choosing a heating device. In a house with external wall insulation and ceilings high.Height of 2.7 meters for warming up 10 square meters. M. Premises are usually necessary 1-1.2 kW of power. Additionally, it is required to add a 20%power supply for rapid warming up the room. With a double.Circuit design, it is required to add another 30% of the power for heating water.

Important! These values ​​are very approximate, for the correct calculation of power, many factors are taken into account (climatic belt, the number and type of windows, etc.). Therefore, it is better to trust the calculations to specialists.

  • The heating area is the maximum area in which the heating boiler will work effectively. If the heated area exceeds the capabilities of the heating device, the room will slowly warm up, the temperature will not rise to the optimal value. The boiler itself will constantly work at the maximum capabilities, which will reduce its service life. When calculating the heating area, it is necessary to take into account all the premises that will be heated, regardless of the presence of batteries or warm floors there.

By the number of contours, gas boilers can be of two types:

  • Single.Circuit. Involved only on the heating of the building;
  • Double.Circuit. Used for heating and hot water supply.
floor, boiler, which, choose

When installing a single.Circuit water heater, hot water supply can be provided with an additional installation of boilers.

Gas heater are with two types of burner.

  • Open atmospheric burner. For the combustion process, it uses oxygen from the room in which it is established that it requires installation of supply ventilation. To remove smoke, a vertical chimney is used at least 4 meters long.
  • Closed burner. The process of supplying air and smoke removal occurs forcibly using fans. Often, a coaxial horizontal chimney is used for this. Through it, smoke removal and oxygen folk from the street occurs at the same time.

The material of the heat exchanger. The main materials for the manufacture of heat exchangers of floor gas boilers are steel and cast iron. There are also models with copper or aluminum details.

  • Cast iron. Perfectly opposes corrosion, durable and reliable material. The disadvantages are its inertia, that is, a slow change in temperature, as well as the possibility of cracking when cold water gets into a hot heat exchanger.
  • Steel. Steel heat exchangers will not suffer from sharp changes in the temperature of the coolant. However, steel is subject to through corrosion.

Note! Currently, many manufacturers use special alloys of cast iron and steel for the manufacture of heat exchangers. This allows you to level many disadvantages of a particular material.

  • Non.Ferrous metals. Copper and aluminum are widely used in the manufacture of boilers.They are repaired, reliable, confront corrosion and are not afraid of temperature changes.
  • The ability to adjust. The wide possibilities of adjusting heating devices allow them to work in optimal economical modes, to ensure a constant comfortable temperature and safety of the boiler itself. Modern programmrators can be configured by very many parameters. However, they require permanent power supply. There are power.Dependent regulators. These are simple and reliable devices, but their set of adjustment functions is minimal.

Tacting: what is it and what is the danger?

By hiring the boiler means the frequency of activations to maintain the required temperature of the coolant. As in the case of any other equipment, constant inclusions and disconnects negatively affect the operational resource, lead to an increase in the load on internal elements. You can reduce the frequency of activation if you adhere to the following recommendations:

  • Correct selection of power, with a small margin;
  • Buying a model with effective modulation of fire;
  • Maintaining the maximum possible volume of the coolant in the circulation circuit;
  • For systems with a small volume of coolant, it is recommended to use the control sensor-terminal sensor that monitors the temperature in the room.

To the issue of choosing power

A competent selection of power will not only allow to provide comfortable microclimatic conditions even in severe frost, but will also exclude hips, work at the limit, fraught with fuel overrun and increasing the load on equipment.

For a standard brick house (masonry. 2 bricks, climate. Moderate), at the height of the ceilings of about 3 meters, you must be guided by the rule of “kilowatt of power for 10 squares”. Recommended power supply. 20 percent for a standard model, 30. For a double.Circuit.

If the heated object is in warm or, conversely, the cold region, is characterized by a significant height of the ceilings, insulated with modern materials, you need to be guided by more complex formulas. For maximum accuracy of calculations, it is recommended to contact a specialist or use calculators on thematic resources.
