Features of Buderus boilers and their operation rules

Buderus boilers are produced by the world famous concern Robert Bosch. For the first time in the heating market, these products declared themselves almost 15 years ago and have since been considered to be one of the best units for organizing household or industrial heating systems.

Brand products Works on any of the following types of combustible materials:

• on gas;
• on all types of solid fuels;
• on diesel fuel;
• on electricity;
• In the line of models you can find and combined products.

Also products may vary by the type of materials from which they are released:

• Pig-iron devices are products of long burning. For them, you can choose wood in wood or pellets, coal or coke. The cast-iron unit is selected for heating the room, whose parameters are not more than 400 m2. The unit is very compact.The cast iron floor heater is equipped with an atmospheric burner. The most popular here are coal products.

• Installations that operate on all possible types of solid fuel (TT), have a steel chamber for combustion and are divided into 8 types depending on the power used (12-45 kW). They will work fine with coal, coke and ordinary wood. Often placed in gravitational heating systems as a completely separate installation or as an additional heating element with the existing equipment that runs on gas. Devices with a steel tank are more often chosen for heating apartments, residential cottages or work spaces from 120 to 300 m2. Steel installations cost much less than cast-iron, solid fuel-fired, and therefore more interesting to the ordinary buyer.

• If you appreciate the high quality of products, then among the models from Buderus you will especially like steel pyrolysis devices - single-circuit and double-circuit. The main chamber of their firebox allows the use of logs up to 58 cm long. These units are produced in 4 versions and have a power of 18 to 38 kW.Heating the space to 300 m2, the unit will not produce ashes and do not need to be cleaned.

Also, brand models are divided by type of placement.

Wall-mounted products have a capacity of 7.8 to 35 kW. It can be single-circuit and dual-circuit devices. Attachments attract stylish design, simplified management and interesting functionality.

Floor-mounted devices will be able to operate on gas and diesel fuel. The choice of buyers are offered as household units of low power, and quite powerful installations, which are perfectly suited for heating large-scale areas of up to 12 thousand m2.

Also, the consumer can always buy very powerful gas installations. In the category of industrial units, you can pick up gas water or steam products from the eminent German concern. In the heating market, they are most often found under the Bosch brand. This technique was released to heat industrial-type buildings and generate huge amounts of steam.Some types of boilers can carry out work on gas, but among them there are diesel models.

Modern and popular condensing devices will allow you to easily use the energy that is emitted by burning combustible material, while reducing the cost of homeowners for heating. A decade or so ago, the problem was that in conventional boilers a certain part of the energy obtained as a result of the combustion of combustible material could not be used (this is the energy from the combustion of fuel and the energy of steam). Today, the latest developments make it possible to quite successfully “collect” this kind of energy, therefore, in the current installations of the condensation type, the efficiency is much higher than that of ordinary products.

Characteristics and technical characteristics of products from the Buderus trademark:

• excellent performance;
• the possibility of moving gas from natural gas to liquefied gas and back;
• convenient temperature control;
• combination with other types of devices;
• proven reliability and ease of management;
• Efficiency up to 93%;
• almost complete lack of noise at work;
• minimum release of toxic components into the air.

The most popular and fashionable models are considered several.

"Logamax U072" - This is the best device for difficult domestic conditions. The gas plant will continue to operate smoothly with sudden drops in voltage, with significant jumps in the level of pressure of the fuel and the coolant. Buyers are offered models from 12 to 35 kW. The technique will have a low level of noise during operation and reliable protection against freezing. Heated space - from 110 to 240 m2.

"Logamax U042-24K" - It is a gas plant with a closed combustion chamber, which uses air from both the plant itself and from the outside for burning fuel. Such a unit can be placed in the attic, in the basement or in any other space, if the conditions for mounting the product allow. The unit of this type has an LED display. The device has a rather high efficiency - 92%.

"Logamax plus GB172" - This is a series of the most technologically advanced gas devices from the Buderus concern. Concern engineers have built into the new devices durable heat exchangers, which are very easy to clean, reliable and high-quality piping and panels,that they are able to control not only the devices themselves, but also their external device. Also thought out the ability to control the system remotely using the Internet through the application.

For boilers "Buderus Logamax" the company produces its own high quality coaxial chimneys. Among the components, you can also find outdoor temperature sensors that connect to Buderus control panels that support weather-dependent controls and make-up taps.

Device series "Buderus Logano" stands out for its floor placement. This is a whole series of various gas and condensation products and solid fuel devices.

The G221 series are cast iron units of relatively low power - from 20 to 42 kW. Quite compact and with a special heat exchanger, whose service life is approximately 30 years. A characteristic feature is a big firebox, so just one bookmark of combustible material is enough for a long time. The efficiency of this model will be only 78%, but for the usual solid-fuel units and this is a very good indicator.

The upgraded 2-circuit model G221 / A is also popular, since it can also be used for pellets. An autoloading system was installed here, which helped to remove the main drawback of modern TT devices - now you can just fill the bunker once, so that for several days you don’t play the role of a stoker.

S111-2 - solid-fuel appliances made of steel, which cost much less than iron products, but also have anti-corrosion resistance due to the use of special alloys. Produced in 7 power variations from 12 to 32 kW. Efficiency parameters reach 74-76%. These heaters are quite popular among the owners of country houses.

Recently, the line was supplemented with more advanced devices "Buderus Logano S131" with parameters of power from 15 to 22 kW. The design of the heat exchanger itself has changed, the furnace chamber has increased in size. Innovation has become more convenient operation of the boiler.

In the most powerful models S131-22H you can also connect elektroten. He will easily be able to support the work of the entire system if a new batch of fuel was not incorporated into it in a timely manner. In any case, these units are considered low-performance and are more often used for heating oversized buildings with an area of ​​up to 220 m2.

S121-2 are products of long burning, which differ from other models, since they do not just burn the firewood, but also reuse the emerging pyrolysis gases. As a result, the performance of devices is growing without increasing the cost of fuel.

S121-2 models are 4 types of boilers from 18 to 38 kW. This is enough to choose the best model for housing in the countryside of any size up to 360 m2. Reviews of the owners also note the almost complete combustion of fuel, so even the ashes need to be removed less often.

Buderus Logica Series - steel products that are designed for high-quality heating of large enough objects. The capacity of the plants in this series will vary between 50-350 kW. But with such high-performance features, Buderus products will need special protection for their core elements. For this reason, their design will be much more complicated than that of conventional solid-fuel devices.

It will also include:

• cooling water tank;
• thermostatic valve;
• safety heat exchanger.

Advantages of Buderus products:

• economy in operation;
• proven reliability;
• adaptation to domestic conditions;
• ecological cleanliness;
• many models.

Installation of any gas equipment must be carried out by service masters if they also have the necessary experience and knowledge, because this procedure will require special care and full compliance with all existing regulations and standards.

Installation of a product from Buderus will consist of a number of stages:

• mounting holders on the desired wall;
• connection of the heating circuit;
• accession of GVS, flue;
• filling the system with coolant (possible antifreeze);
• start-up and setup of operating modes.

The installation of the Buderus device is carried out in rooms with an area of ​​7.5 m2 and the height of the ceilings here should not be less than 2 m. In such a space there must be a chimney and high-quality ventilation.

Depending on the type of heating system (and it can be one- or two-pipe), the number of pipes that need to be connected to the appliance may be different. In any case, everything must begin with the removal of the plugs from all the fittings of the installation.

It is better to choose dual-circuit models to turn off the heating in the summer, but continue to calmly use the hot water. You need to know that the nozzles that supply cool water are on the device to the left of the center, and the inlets that are already heated are on the right.

Connect the device to the gas line can only specialist who has special approval. At the end of the connection process, the product is also checked by a gas service specialist. He will also produce the very first start-up of the installed equipment. Be sure to check the entire system for its complete tightness. All connections that are leaking will need to be sealed immediately.

For power supply, a separate wiring is conducted with a mandatory connection to the voltage regulator circuit in order to protect the automation, and it is also mandatory that the product is grounded.

Heating installations from Buderus are considered extremely reliable and are characterized by a long service life, but do not forget about timely diagnosis and prevention. A number of these simple procedures will significantly save your money and nerves, as it will minimize the risk of breakdowns or accidents.

Error 6a (2nd indicator blinks) appears if the unit cannot detect a flame on the burner. In order to control the flame, a special electrode was invented; through it, when burning, there is not a very large charge of current. The control board monitors this current all the time. If the current disappears, then this kind of error manifests itself.

In order to correct this error, there are 2 ways:

1. hold the “OK” button slightly pressed until the breakdown signal disappears, after which the device will start functioning again;
2. turn on the unit and turn it off completely.

Error code 3c (4th light is on). When this error occurs, the board responsible for controlling the unit does not receive the desired signal from the pressure switch.This way the contacts may not close after the fan starts working. The pressure switch is installed to determine the conditions of the output of the combustion products.

To correct the error, you will have to carefully inspect all related elements and check them for operability, if necessary, to clean them from clogging.

Error code 4c (the very first indicator flashes on the screen) appears either at a low pressure level or at an elevated temperature at the exit of the heat exchanger. In this case, use a pressure gauge and double-check its readings. If the pressure level in the system is low - less than 0.5 bar, you just need to feed the product.

Error code 2e (the first 3 lights blink). The error lies in a rather rapid increase in the flow temperature, that is, the coolant, leaving the heat exchanger, warms up quickly enough. This may be due to poor circulation of the coolant present in it.The reasons for this may be a malfunction of the circulation pump or poor performance of the device, a heat exchanger littered with debris or scale, air accumulation in the system. Repairing the pump, cleaning the heat exchanger and bleeding air from the system will help fix this problem.

If the unit does not heat the hot water, and no error is shown on the indicator, the cause may be the failure of the flow sensor. To do this, clean the sensor fan.
