  1. The assembly is not always German - some models are produced in other countries, including in Russia, in the city of Engels. Despite the fact that specialists on the manufacturer's original equipment observe the assembly, user reviews indicate that domestic-assembled Bosch gas boilers still differ from the previous German quality;
  2. High price. Yes, the price is somewhat overpriced, if you compare products with other leading brands, then for Bosch boilers it is 10-15% higher.

Varieties of Bosch gas boilers

The assortment of the German manufacturer of boiler equipment includes various models by the number of circuits, the installation location and the principle of operation. Let's consider them in more detail.

floor standing

Units with a floor version are highly economical, they will not consume a lot of fuel. The instrument package includes a standard one that can monitor the level of gas supply and traction. If there are any failures and malfunctions, then an emergency shutdown of the device occurs. Floor models are well suited for areas where power supply problems are common.

Gas floor standing boilers BOSCH GAZ 2500 F

Settings floor type very often used to supply heat to large rooms. Their area reaches from 130 to 500 m². This is due to the high power of the units, it is 30 kW.

The disadvantages of Bosch floor boilers include the following factors:

  • too large equipment;
  • the need to equip a separate boiler room;
  • there are difficulties with the withdrawal and adjustment of hot water supply.

wall

Wall-mounted units are equipped with circulation pump , security team and expansion tank. The devices themselves are compact in size, they are easily attached to the wall. Some models have a forced removal of combustion products. To do this, a small pipe is mounted, which is brought out into the street through an adjacent wall.

Wall-mounted Bosch gas boilers have gained wide popularity due to the automated work system. The device itself maintains a certain temperature in the house. For example, during the day the temperature during the day will be stable at +18°C, and in the evening at the selected time it will go to +23°C.

If desired, you can connect a warm floor to the boiler with the ability to configure or set certain parameters using the built-in control panel.

single circuit

This is the simplest type of Bosch gas boilers, they are intended only for supplying heat to houses and non-residential premises. Their package includes one, the devices are equipped with a built-in piping, which includes expansion tanks and circulation pumps. There are both small-sized devices with low power ratings and very powerful devices that are designed to supply heat to large rooms on the market.

The main advantage of models with a single circuit is simple design, because the number of elements that make up the device is reduced to a minimum. The units are characterized by high reliability. However, if you want to have hot water in the house, then you will have to look for alternative way filing hot water. For this, electrical storage water heaters, geysers and instantaneous water heaters.

Dual circuit

A Bosch gas boiler with two circuits is a good alternative to a single-circuit unit. In terms of dimensions, they are almost the same, differ only in internal equipment.

Double-circuit units operate with two heat exchangers and with. In the first case, the water in the hot water circuit is heated by water from the heating circuit, which moves through the main heat exchanger in a closed volume. In another case, the heat exchanger seems to be absent, since it is hidden inside the main exchanger.

It is worth noting that such a scheme for the structure of Bosch by-pass units is considered not very reliable. Regardless of the design of the double-circuit boiler, such devices save free space in room.

With open combustion chamber

Boilers with an open firebox are designed according to the traditional scheme, which provides for the process of gas combustion with a natural influx of atmospheric air - it is on this principle that flow-through boilers operate. gas water heaters and ordinary boilers of floor execution.

Bosch Condens 2000 W 24 Kw

The air intake here takes place directly from the room in which the boiler is located. The removal of combustion products is carried out through a traditional chimney, in which draft is always present. Therefore, rooms in which gas boilers with an open firebox are installed must have good ventilation and strictly comply with fire safety rules.

Wall gas Bosch boilers very often called atmospheric, since combustion occurs at normal atmospheric pressure. The advantage of an open burner is that the equipment is very simple, and as a disadvantage, one can note a rather low productivity and the fact that the gas does not burn completely. But such a burner works almost silently.

With closed combustion chamber

Bosch wall-mounted boilers with a closed combustion chamber are also called turbocharged. The combustion of gas here takes place in a special burner with forced air supply - it is taken from the outside of the room by means of high power. The combustion products are removed in the same way. Since they are removed by force, draft in the chimney is not required. That is why, together with turbocharged boilers, they are used, which are mounted in the nearest wall.

Bosch gas wall-mounted boilers with a closed combustion chamber have a large number of advantages:

  • gas is burned as efficiently as possible;
  • boiler performance is high;
  • reduced amount of harmful emissions;
  • thanks to the modulating burner, the load on metal components is not so high;
  • devices can be mounted in any room, even in those in which there is no ventilation.

There is also a significant minus - this is noise, which is due to powerful fans included in the design of the unit. They perform the function of air intake and removal of combustion products. Many models with modulating burners have adjustable speed, due to which, at light loads, the devices are not so noisy.

The key disadvantage of turbocharged wall-mounted gas boilers is that they are equipped with many components that adversely affect the reliability of the units.

Condensing

In the combustion products of classic gas boilers, called convector boilers, a large amount of thermal energy remains, incl. in the form of heated water vapor. There are technologies that make it possible to take this heat and send it to the heating system. Just in order to cope with this task, they were developed that have the ability to intelligently use the generated heat.

Condensing double-circuit gas boiler Bosch Condens 2000 W ZWB

The manufacturer indicates that the efficiency of these boilers is 110%, but in reality this is nothing more than a marketing ploy, in fact, productivity increases by about 5-10% of the original figure, but never reaches 100%.

Advantages of Bosch condensing boilers:

  • gas is burned efficiently;
  • fuel is consumed very economically;
  • for environment devices are absolutely safe.

As disadvantages, it is worth noting the complex design, the need to drain condensate, which occurs during the condensation of water vapor.

All wall-mounted condensing boilers have a closed firebox.

Today they are installed in individual apartments, private houses, and also in buildings of the small enterprises. Among the most preferred brands, Bosch is a well-known German brand. Many consumers already know that a Bosch gas boiler, double-circuit or single-circuit, will become a reliable and durable source of heat. Let's see what Bosch equipment is and what are its characteristic features.

Features of Bosch gas boilers

Heating equipment from well-known manufacturers is characterized by a large margin of safety and reliability. Yes, and it lasts much longer, delighting consumers with warmth. We can say the same about Bosch gas boilers, which have earned particular popularity among domestic consumers. They are available in many configurations and are represented by a large number of models of different capacities.

The Bosch gas boiler is a smart choice for those who are going to create an autonomous heating system in their home. The device mounted in the system will show high efficiency, will please you with the absence of problems in operation and the minimum number of breakdowns. Consider the main advantages of Bosch gas boilers:

Unfortunately, it was not without some drawbacks:

  • Not always German assembly - yes, some models are really made in other countries, including in Russia, in the city of Engels. Despite the fact that the assembly is carried out under the supervision of specialists on the manufacturer's original equipment, the owners' reviews indicate that domestically assembled Bosch gas boilers do not differ in the same German quality;
  • Somewhat overpriced - this is true, but only when compared with the products of some little-known manufacturers. In comparison with leading brands, the cost of equipment is approximately the same, but can vary within 10-15%;
  • Limited selection in stores. This problem solved with the help of numerous online stores.

Cons are not the worst, they can be neglected. But you will get reliable heating equipment at your disposal.

Bosch gas boilers and their varieties

If you are going to buy a Bosch wall-mounted gas boiler, you will definitely need information about the types of equipment being sold. The choice of consumers are presented:

  • Single-circuit heating units;
  • Double-circuit gas boilers Bosch;
  • Models with open and closed combustion chambers;
  • condensation models.

Let's consider this equipment in more detail.


Before us are the simplest Bosch gas boilers, designed exclusively for heating residential and non-residential premises. They are built on the basis of a single heat exchanger and are equipped with built-in piping - these are circulation pumps and expansion tanks. Consumers can choose from both small units, with a capacity of several kilowatts, and very powerful ones, focused on heating large areas.

The main advantage of single-circuit models is their simplicity - inside we will find a minimum of nodes, which makes the technique more reliable. But in this case, you will have to look for a way to organize the preparation of hot water. For this, electric storage water heaters, gas water heaters, heaters are used. indirect heating or electric instantaneous water heaters.


Gas double-circuit boiler Bosch will become great alternative single loop option. In terms of size, these devices are almost identical, differing only in the internal filling. Double-circuit devices are built according to schemes with two heat exchangers or with a bithermic heat exchanger. In the first case, the water in the DHW circuit is heated by water from the heating circuit, which circulates through the main heat exchanger in a closed volume (at this time, the heating does not work).

In the second case, there is no second heat exchanger, since it is hidden inside the main exchanger. Such a scheme for the construction of double-circuit gas boilers Bosch (and other brands) is not the most reliable. Regardless of how the double-circuit unit is built, it allows you to save free space in the house, replacing two devices at once - a boiler and a water heater.

Thermal engineering experts advise purchasing Bosch double-circuit gas boilers, built according to a scheme with two heat exchangers - they are more reliable and durable.


Bosch gas boilers with an open combustion chamber are created according to the classical scheme, which provides for the combustion of gas with a natural influx of atmospheric air - this is how instantaneous gas water heaters (columns) and simple floor-standing boilers work. The air here is taken directly from the room in which the unit is installed. The products of combustion are sent to a traditional chimney, in which there is always draft. Therefore, the premises where Bosch open gas boilers are installed must be ventilated and meet strict fire safety requirements.

Bosch wall-mounted heating boilers (and other brands) are often called atmospheric, since combustion occurs at normal atmospheric pressure. The advantage of an open burner is the relative simplicity of the equipment, the disadvantage is a lower efficiency and incomplete combustion of the gas. But such a burner is distinguished by a low noise level - only the gas itself makes noise in it.


Bosch closed wall-mounted gas boilers are called turbocharged. The thing is that the gas burns here in a special burner with forced air supply - it is taken from outside the room with the help of a powerful fan. The products of combustion are removed in a similar way. Since they are removed by force, draft in the chimney is not needed. Therefore, together with turbocharged units, short coaxial chimneys, which are displayed outside the nearest wall.

Bosch gas wall-mounted boilers with a closed combustion chamber have a lot of advantages:

  • More high efficiency due to more efficient gas combustion;
  • Reduced number of harmful calls;
  • Reduced thermal load on metal components (due to modulating burner);
  • Possibility of installation in any premises (including without ventilation).

There is also a certain drawback - this is an increased noise level, since the design of the equipment contains powerful fans responsible for air intake and removal of combustion products. In most models with modulating burners, they have variable speed, which reduces noise somewhat at low loads.

The main disadvantage of Bosch turbocharged wall-mounted gas boilers is their increased complexity– the more nodes, the less reliability.


In the combustion products of traditional gas boilers, which are called convector boilers, a lot of heat remains, including in the form of heated water vapor. There are technologies that allow you to take this heat and send it to the heating system. Especially for this, Bosch condensing wall-mounted gas boilers were created, which can use the generated heat to the maximum.

There is a slight subtlety here - the manufacturer says that the efficiency is up to 110%, but in fact this is nothing more than a marketing ploy (such efficiency is contrary to the laws of physics). In reality, the efficiency increases by 5-10% of the original figure, but never reaches 100%.

Advantages of Bosch condensing wall-mounted gas boilers:

  • Efficient gas combustion;
  • Economical fuel consumption (up to 10%);
  • Caring for the environment.

There are also disadvantages - increased complexity, the need to drain condensate, which is formed as a result of condensation of water vapor.

All Bosch wall-mounted condensing gas boilers are built according to the scheme with a closed combustion chamber.

Popular Models
