Buderus Logano technical specifications. Technical characteristics of German Buderus boilers. Control system capabilities

Buderus Logano G234 is a floor-standing gas cast iron boiler. The model is equipped with atmospheric gas burner, allowing for preliminary mixing of the incoming gas. The boiler power of this model is 60 kW.

Features of the Buderus Logano G234 model

• The models are equipped with a conversion kit. Its presence allows you to independently switch the boiler to consume another type of gas. For example, from natural to liquefied or a mixture of propane and butane.
• It is also possible to combine the boiler with other water heating systems and control units from the manufacturer.
• The heat exchanger in the boiler is made of cast iron. Thanks to this, its durability will allow it to “outlast” similar models with heat exchangers made of copper and steel.
• The burner design has no moving parts, which has a beneficial effect on its reliability. It is worth noting that, structurally, Buderus Logano G234 comes with open camera combustion. This involves their location in a separate basement, since the air to support the combustion process is taken from the room.
• Another advantage of choosing this model will be the low noise level, due to which the boiler is practically inaudible during operation.
• The modular system for controlling and connecting other boilers and tanks suggests the possibility of increasing the capabilities of the heating system. Potential gas boiler already in the basic version it is enough to provide heating for a room of up to 400 m2.

Technical characteristics of the Buderus Logano G234 model

• rated heating output at natural gas is 60 kW,
• thermal combustion power - 65 kW,
• temperature flue gases escaping into the chimney - 95°C,
• the required draft level for correct operation of the boiler is 3 Pa,
• maximum permissible temperature supply line - 115°C,
• acceptable operating pressure should not exceed 4 bar,
• allocation carbon dioxide no more than 5% at the moment of maximum load, which makes this boiler model one of the most environmentally friendly and harmless to human health,
• the weight flow of the exhaust flue gases is 0.05 kg/s.

Installation of the Buderus Logano G234 boiler: step-by-step instructions

1. The boiler itself is supplied with a kit, which has a built-in flow fuse, a built-in burner and a control device, which is packaged separately from the overall structure.

2. During installation, it is worth considering that when installing the boiler, it is necessary to leave free space from the walls. The distance from the back of the boiler wall to the wall of the room should be at least 50 cm, the same applies to the adjacent wall if you plan to place the heating boiler closer to the corner.

3. The floor surface itself must be flat. Even minor differences in floor level are not allowed. Since the boiler does not vibrate during operation, it is possible to adjust wedges or other gaskets under problem areas to ensure the stability of the structure.

6. Installation electrical system much more complex and includes many stages:

• First, remove the protective cover and the casings of the connecting terminals,
• the pressure control device is inserted into the grooves,
• the temperature sensor tubes are inserted into the cutout on the front of the casing,
• then the adjustment device is slightly shifted into the groove so that the rear elements fit into their grooves,
• the device is screwed to the housing cover,
• after this, according to the instructions, all elements in the electrical circuit are connected step by step.

It is important to remember that installation, connection and testing of the boiler’s functionality should only be carried out by a certified specialist representative of the company. Otherwise, agreements on provision warranty service are automatically cancelled.

After the boiler has been installed, all elements are checked to ensure they have the proper degree of tightness. When checking, the control pressure on the burner reaches 150 mbar.

Solid fuel boilers Buderus - review of cast iron and steel models

Today, heating units operating on solid fuel do not lose their popularity. They are widely used in areas where there is no connection to gas mains. In this article we will look at what they are solid fuel boilers Buderus, let us note the principle of their operation, advantages and disadvantages.

Design and principle of operation of the Buderus solid fuel boiler

The technical characteristics of Buderus solid fuel water heating units are significantly higher than those of analogues produced by other manufacturers. High performance thermal efficiency are directly dependent on design features equipment.

Find out the price and buy heating equipment and related products you can find here. Write, call and come to one of the stores in your city. Delivery throughout the Russian Federation and CIS countries.

Let's look at the functionality of Buderus solid fuel boilers:

1. A manufacturer from Germany has designed a system that greatly simplifies installation work. The housing of the units has several different outlets required for connection to heating system and boiler indirect heating.
2. The principle of operation of household solid fuel boilers long burning Buderus lies in the fact that during the heating process they use gas generation mode. The specificity of such work lies in the ability of any kind solid fuel release gas. Under certain conditions (when the supply of oxygen is limited and the temperature exceeds 200°C). CO is burned in a separate chamber, which provides additional heat.
3. Steel pyrolysis boilers operating on solid fuel are constructed of two combustion chambers. In one, the fuel combustion process is carried out, in the other, the gases produced in the process are burned.
4. Buderus boilers are absolutely universal; they can operate on: wood waste. In other words, they are absolutely unpretentious regarding the type of fuel.
5. Buderus units are safe to operate. The coal-wood pyrolysis boiler is equipped with multi-level protection against overheating of the coolant. Automation is responsible for regulating the combustion process. The design also includes a safety valve that protects the device from overheating. Auxiliary safety can be achieved thanks to security group, which is mounted on the hot coolant supply.
6. The Buderus solid fuel boiler made of steel and cast iron is used for connection to heating systems with natural and forced circulation coolant. The performance of household models is quite sufficient to supply heat to rooms with an area of ​​up to 500 m². Water heating using boilers of this brand is suitable for indoor industrial type, shopping centers, warehouses.
7. The units include steel or cast iron heat exchangers; each type has its own pros and cons. Cast iron models have high warm specifications And long term services. Models made of steel weigh less and are less expensive.

The Buderus TT boiler is designed for heating at permanent residence. At sub-zero temperature the coolant water freezes, which can lead to circuit rupture and failure of the water heating equipment.

Types of solid fuel boilers Buderus

The company produces several modifications heating devices on solid fuel, which differ in the material of manufacture.

1. Buderus cast iron units are long-burning devices. They are equipped with a fan or turbine that supplies air to the combustion chamber. The models are presented in five variations with different power ratings. The fuel is ordinary wood or pellets, coal or coke. The devices are installed in heating systems of pump or gravity type, both independently and in conjunction with gas or diesel heating devices. The technical characteristics of the Buderus solid fuel boiler make it possible to use it to supply heat big houses, production premises, the size of which is no more than 400 m². The products are characterized by a long fuel combustion process, they are economical, their design is reliable and easy to install. Due to the fact that the devices are very compact, you can install them in small rooms. As a disadvantage, which is common to all models, we can note the need to constantly load fuel with your own hands. The exception is the innovative development of the company - the solid fuel boiler Buderus Logano G221/A, which is equipped with automatic fuel supply. He's different high performance, the efficiency reaches 80%, but at the same time its price is significantly higher than that of other models. The cost of such a unit is approximately 190,000 - 215,000 rubles.
2. Long-burning boilers made of steel with a large loading chamber. Available in 8 variations with power from 12 to 45 kW. Such devices can be heated with wood, coal and coke. According to the instructions, a steel solid fuel boiler is installed in pressure and gravity heating systems as an autonomous or auxiliary element together with gas and diesel equipment. Can be installed in apartments, cottages, small-sized or industrial premises, the area of ​​which varies from 120 to 300 m². Due to the impressive size of the firebox, the unit can operate in long-term burning mode. Thanks to the built-in economizer, thermal energy distributed throughout the room efficiently. User reviews indicate that Buderus solid fuel boilers do not have any serious operating defects. In order for the combustion process to be more efficient, before loading coal into the firebox, you need to sort it to separate large from small. The price of steel appliances is slightly lower than their cast iron counterparts. For example, a boiler with a power of 24 kW, designed to heat an area of ​​190 m², costs from 38,000 to 52,000 rubles.
3. Universal long-burning steel pyrolysis-type devices are equipped with primary and secondary combustion chambers. They are produced in four variations, the power of which varies from 18 to 38 kW. Maximum size The logs that the combustion chamber can accommodate is 58 cm. The units are also equipped with a control panel, which is responsible for regulating the operation of the fan, and they also include a smoke exhauster activation system, which does not allow smoke to enter the room when the combustion compartment is opened. The ash pit is lined with fireclay bricks. Such units can be used in pump or gravity heating to supply heat to cottages and industrial premises, the area of ​​which reaches 300 m². The key advantage of products in this series is that they consume much less fuel. At the same time, their productivity is 5-7% higher than that of other models of solid fuel boilers. There is practically no smoke in them, so you won’t have to clean the firebox every week. The disadvantages include the high price, which is equal to 90,000-110,000 rubles.

Problem-free installation of burners from another manufacturer on a plate with holes drilled for the burner. Any diesel or gas fan burner, the test sample of which complies with DIN 4787 or EN 267 and DIN 4788 or EN 676, or a burner with a CE mark, is allowed for installation. The burner is mounted on a fixed plate. Burner plate with drilled holes can be purchased at additional order. If it is necessary to reduce dimensions during transportation, it is possible to supply the boiler in a modified version (with the base frame dismantled).

BUDERUS Logano SK625 technical specifications

The German company Buderus, part of Bosch Thermotechnology GmbH, entered the Russian market not so long ago - in 2004. Thanks to a professional approach to the heating system as a single whole, the manufacturer provides comprehensive supplies of energy-efficient heating equipment.

Among innovative products, Buderus boilers deserve special attention, the technical characteristics of which were developed by company specialists for the economical, safe and environmentally friendly operation of the equipment.

Variety of models

The line of German-made heat generators is classified according to several parameters:

• Type of installation (wall or floor).
• Type of fuel used (diesel, gas, electric, solid fuel and combined).
• Type of combustion chamber (open or closed).
• Heat exchanger material (cast iron, copper or steel).

Simple and in an accessible way A comprehensive solution to the problem of heating and hot water supply is to install a double-circuit wall-mounted boiler. Heating is carried out by a bithermic heat exchanger using the flow method up to 40-60 °C with a capacity of 10-15 l/min. This volume of flow is enough for a maximum of two water intake points located at a short distance from the source.

A representative of the double-circuit model, the Buderus Logamax U044-24K gas wall-mounted boiler is a 24 kW circulation water heater that operates with strict priority on DHW. Thanks to the built-in turbine, it quickly adapts to the required volume of hot liquid at a given temperature.

A single-circuit heater is capable of providing heating in combination with a boiler indirect type. For example, the household heating boiler Buderus Logamax U052-28 operates according to the classical scheme: a built-in three-way valve “recognizes” the DHW mode using a temperature sensor and switches the supply of coolant to the heat exchanger. This “union” of equipment guarantees a constant flow of hot liquid from 60 to 200 liters.

1. Gas boilers Buderus is produced with various functional characteristics:

• With forced or natural draft.
• Closed or open combustion chamber.
• Pressurized or atmospheric burner.
• With steel or cast iron heat exchanger.
• Single or double circuit.
• Power from 7.8 to 270 kW.
• Wall or floor.

Cost of gas boilers Buderus U072 mounted type can be called democratic - from 26 thousand rubles, which is 2 times less than the price of a stationary installation option - from 61 thousand rubles.

2. Gas condensing boilers are environmentally friendly and economical compared to traditional ones. Thanks to the use of additional energy from exhaust combustion products, consumption was reduced and efficiency increased significantly (by 10%). The price range of more advanced energy-efficient models starts from 60,000 rubles.

3. Solid fuel Buderus are presented in floor-mounted traditional version. Long burning units with cast iron or steel body can operate autonomously or as backup in a series-connected connection with boilers using alternative sources.

Gas generators increase the thermal efficiency of solid fuel combustion due to the pyrolysis process of decomposition of organic substances. As a result of complete combustion of coal or firewood, there is virtually no release of organic gases into the environment. The main disadvantage is the price of pyrolysis solid fuel Buderus Logano.

4. Supercharged ones can operate on diesel or natural gas, depending on the type of burner, which is easily reconfigurable. Each design uses Thermostream technology, which protects against the formation of condensation and “thermal shock” of heat exchange surfaces. The low-temperature floor-standing combi boiler Buderus Logano G215, thanks to the optimized firebox design, consumes fuel economically, while providing high efficiency thermal transfers.

5. Electric models silent, compact and easy to use. Boilers with a power of 2-18 kW are supplied with expansion tank(7 l) and safety valve, which for more powerful options (22-66 kW) must be ordered separately.

Comparative characteristics of boilers from Germany Buderus

Before purchasing a Buderus boiler, you need to familiarize yourself with the main characteristics of the units:

• Type of fuel. The choice of heat source depends on availability, cost and ease of use individually for each consumer. Before choosing Buderus solid fuel boilers, you should provide a special room for equipment.
• Boiler power. This indicator directly depends on the area of ​​the heated structure and the degree of insulation and is determined by calculation.
• Installation type. Wall-mounted devices are compact and do not require separate room for installation. But the higher technical characteristics of Buderus floor-standing boilers make it possible to use them at heat generating stations that can provide energy to municipal and autonomous enterprises, local heating networks and industrial heating systems.
• Heat exchanger material. The steel thermal transfer element is common due to its low cost and good ductility of the metal, but at the same time it is susceptible to corrosion and has a large volume, which entails excessive fuel consumption. Cast iron has high chemical resistance, but it is susceptible to cracking as a result of temperature changes, and the price is higher. Copper is the most corrosion-resistant metal, has low weight and excellent thermal conductivity.

User opinions about Buderus

“7 years ago gas was installed in the village - I purchased a Buderus Logamax U044-24K. The choice was made based on the type of installation: wall-mounted does not require a separate room and installation is simple. The power is enough for a house of 120 m2 and provides hot liquid for household needs.”

Anton Pirin, Ivanovo.

“We decided to buy a long-burning boiler Buderus in new house made of timber for 150 square meters. The bookmark is enough for 12 hours of work - morning and evening. There are no foreign odors or ubiquitous black dust. We connected an indirect heating boiler, now the wood-burning pyrolyzer heats the house and heats up the water.”

Anna Vanina, Moscow.

“After a long search for a heating boiler, we chose the Buderus Logamax plus GB072. The house is warm hot water around the clock. Despite the rather high cost, the condensing unit really allows you to save gas consumption - in two years, bills have been reduced by 15%.

Vlad Yatsenko, Krasnodar.
