A bit of history

Junkers (Junkers) was established in 1895 for industrial production of gas devices for individual consumers. Production was located in the city of Düsaau. The company name appeared thanks to the name of the German industrial engineer Hugo Junkers, the famous inventor of the XIX century in the area of \u200b\u200bthermal techniques, having almost two hundred inventive patents.

By 1904, the company mastered the production gas water heaters and other equipment. The use of advanced technologies made it possible to develop a gas supply management system depending on the flow rate hot water.

In 1932, due to the global crisis, the Junkers management sells his concern Bosch, which continued the development of the concern and its production. New plants were opened, improved quality control of products, continued the development of new technologies, for example, embodied the idea of \u200b\u200bpiezorocal flame for columns. After 10 years, heating boilers were launched in production attachment. And in 1985, mass production of gas boilers with an eco-friendly system of pure combustion began. The company produces household gas devicesin which the combustion chamber is closed and there is no need to connect the chimney.

Today, Bosch Thermotechnik is one of major producers devices gas heating in Europe.

The product range of the Junkers brand includes gas outdoor and wall boilers, solid fuel boilers, columns for water heating.

Additional elements and spare parts for aggregates of this brand are inexpensive, and in quality are superior to competitors. The company establishes a 25-year warranty period for its products.

German company Junkers One of the first to develop and implemented a gas pressure control system depending on the flow of water, as well as the function of eco-friendly gas burning.

The assortment of Junkers presents installations with a closed and open furnace chamber, in an outdoor and wall-mounted version, with one and two contours. All gas boilers brand Junkers are granted a 25-year warranty.

Condensation equipment

Junkers has a mounted condensation boiler closed Camera combustion. Depending on the configuration, it can be installed for the heating of rooms up to 500 square meters. m. manufactured in three basic equipment:

Condensation models have a small gas consumption, which reduces the cost of heating by 30-40%.

Wall-mounted equipment (atmospheric)

Hinged single-circuit and dual-circuit gas boilers of heating Junkers, with an open combustion chamber (atmospheric) are presented with a series of Ceraclass, in which two main modifications are: Comfort and Excellens.

• Comfort - The boiler device allows you to reduce the number of possible faults and increase the service life. A self-diagnosis program has been installed, information about problems in work and faults is issued on the LCD display.
  In the basic configuration, Comfort is all the necessary equipment: circulation pump, Gas burner control, sensors and devices that protect against overheating.
• Excellens - The modification includes as wall-mounted single-mounted gas heating boilers Junkers brands and dual-circuit counterparts. Have high performance. Can connect to the system smart House. The possibility of connecting several heating systems At the same time.

Outdoor boilers

Outdoor gas boilers Junkers are designed for household and industrial applications. The maximum performance reaches 56 kW, which is sufficient to maintain a comfortable room in the room to 500-600 m².

The connection of two floor gas heating cats Junkers to one network (cascade) is allowed. If necessary, you can install an indirect heating boiler.

The advantage of models of floor boilers of heating Junkers is that their heat exchanger is made of refractory cast iron. This made it possible to increase the coefficient of heat transfer, as well as the operating deadlines.

In floor units, according to the manufacturer's assurance, antifreeze can be used for boilers. This increases the heat transfer in heating several times, and also prevents the heating system from defrosting.

Output and commissioning

Connecting the boiler does not require the installation of additional circulation equipment. The design includes a pump, expansion tank, Sensitive automation and control unit. All models can additionally be equipped with room temperature sensors.

Installation of water treatment is required. Interior design The heat exchanger is sensitive to the effects of the aggressive medium, so before entering the supply of the heating system to the boiler, the coarse and fine filters are installed.

Maintenance of the boiler is simply carried out, thanks to the front removable panel, which opens access to important nodes. Cleaning the heat exchanger is carried out at the beginning and end heating season. Fault diagnostics are carried out in automatic mode, the results are displayed on the display.

Advantages and disadvantages of choosing boiler Junkers

According to consumer reviews, several factors affect the quality of work of the boiler: technical conditions operation, correctly exhibited settings and disadvantages in the design. The most difficult and expensive breakdown is the failure of the control module. Replacing the board will cost a third of the cost of the boiler.

Another common problem occurs as a consequence of poor boiler service. The principle of equipment operation is based on the use of sensors that prevent overheating of the coolant. So, the automation works in the presence of large number Says in the furnace. The water heating temperature in this case does not rise above 45 ° C.

The rest of the boilers, Junkers work, as it should german equipment - with accuracy, performance and reliability. Junkers is good decision For those who primarily appreciate quality and pay for it.
