Consider what is the functionality of Buderus solid fuel boilers:

A manufacturer from Germany has designed a system that greatly simplifies installation work. In the body of the units there are several different outlets necessary for connecting to the heating system and the boiler indirect heating.
The principle of operation of household solid fuel boilers long burning Buderus lies in the fact that in the process of heating they use the gas generation mode. The specificity of such work lies in the ability of any type of solid fuel to release gas. Under certain conditions (when the supply of oxygen is limited and the temperature regime exceeds 200 ° C). CO is burned in a separate chamber, so additional heat is obtained.
Steel pyrolysis boilers operating on solid fuels are designed from two combustion chambers. In one, the process of fuel combustion is carried out, in the other, afterburning of the gases produced in the process takes place.
Buderus boilers are absolutely universal, they can function on:, woodworking waste. In other words, they are absolutely unpretentious to the type of fuel.
In operation, Buderus units are safe. 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 through security group, which is mounted on the supply of hot coolant.
The Buderus solid fuel boiler made of steel and cast iron is used for connection to heating systems with natural and forced circulation of the coolant. The performance of household models is quite enough to supply heat to rooms whose area reaches 500 m². Water heating using boilers of this brand is suitable for rooms industrial type, shopping centers, warehouses.
The units are supplied with steel or cast iron heat exchangers each type has its pros and cons. Cast iron models have high heat specifications and long service life. Models made of steel - weigh less and their cost is lower.

TT boiler Buderus is designed for heating at permanent residence. At sub-zero temperatures, the water coolant freezes, which is fraught with a circuit rupture and failure of the water heating equipment.

Varieties of solid fuel boilers Buderus

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

Pig-iron units Buderus are devices of long burning. They are equipped with a fan or turbine that supplies air to the combustion chamber. Models are presented in five variations with different power ratings. The fuel favors ordinary wood or pellets, coal or coke. Devices are installed in heating systems pump or gravity type, both autonomously 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, industrial premises, the size of which is not more than 400 m². Products are characterized by a long process of fuel combustion, 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 minus, which is common to all models, it can be noted that you need to constantly load fuel with your own hands. An exception is the innovative development of the company - the solid fuel boiler Buderus Logano G221 / A, which is equipped with automatic fuel supply. It is characterized by high performance, efficiency reaches 80%, but at the same time its price is much higher than that of other models. The cost of such a unit is approximately 190,000 - 215,000 rubles.
Long-burning boilers made of steel with a large loading chamber. Available in 8 variations with power from 12 to 45 kW. You can heat such appliances with wood, coal and coke. According to the instructions, a steel solid fuel boiler is mounted 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 in size or industrial premises, the area of \u200b\u200bwhich 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 shortcomings in their work. In order for the combustion process to be more efficient, before loading coal into the furnace, it is necessary to sort it in order to separate large from small. The price of steel appliances is slightly lower than that of 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.
Universal pyrolysis-type steel long-burning 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. The maximum size of the logs that the combustion chamber can accommodate is 58 cm. The units are also equipped with a control panel that is responsible for adjusting the operation of the fan, and they also include a smoke exhauster activation system that prevents smoke from entering the room when the combustion compartment is opened. The ash pan is lined with refractory bricks made of fireclay. Such units can be used in pump or gravity type heating to supply heat to cottages and industrial premises, the area of which reaches 300 m². The key advantage of the products of this series is that they consume much less fuel. At the same time, their productivity is 5-7% more than that of other models of solid fuel boilers. Cinder practically does not appear in them, so you do not have to clean the firebox every week. As disadvantages, one can single out a large price, which is equal to 90,000-110,000 rubles.

General information about boilers Buderus Logano S111

Even a special search for negative reviews about the boilers did not give anything. Although, it would seem, for more than three hundred years of existence of the brand, flaws should have appeared. However, no matter how hard it is to believe, there is no negative information.

For all modern models boilers have a factory warranty of 2 years at the time of launch. When used correctly Maintenance is required once a year and is carried out by the installer during the warranty period.

Of course, quality costs money. On the other hand, the miser pays twice and it is easier to buy reliable and durable equipment once than to change components every year.

The equipment requires appropriate maintenance, therefore, when purchasing a boiler, it is necessary to carefully study the operating instructions. In terms of heating level, this boiler can only be surpassed by Buleryan furnaces, which, at an average price of five times less, heat the house just as well, and the time spent on heating is less. Hence the conclusion: you should first consult with several experts in order to determine what type of heating boiler to put in your house.

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

Features of the Buderus Logano G234 model

The models come with a conversion kit. Its presence allows you to switch the boiler to the consumption of another type of gas on your own. For example, from natural to liquefied or to 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 “survive” similar models with copper and steel heat exchangers.
The design of the burner has no moving parts, which favorably affects its reliability. It is worth noting that Buderus Logano G234 is structurally supplied with an open combustion chamber. This provides for their location in a separate basement, since air is taken from the room to support the combustion process.
Another advantage in the direction of choosing this model will be the low noise level, due to which the boiler is almost inaudible during operation.
Modular control system and connection of other boilers and tanks provides for the possibility of increasing the capacity of the heating system. capacity gas boiler already in the basic version, it is enough to provide heating for a room up to 400 m2.

Technical characteristics of the model Buderus Logano G234

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

1. The boiler itself comes with a kit that has a built-in flow protector, built-in burner and control device, which is packed separately from the overall assembly.

2. During installation, it should be taken into account 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 must be at least 50 cm, the same applies to the adjacent wall if it is planned to place the heating boiler closer to the corner.

3. The floor surface itself must be even. Even the presence of minor differences in floor level is not allowed. Since the boiler does not emit vibrations during operation, it is allowed to fit wedges or other gaskets under the problem areas to ensure the stability of the structure.

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

first, the protective cover and covers of the connecting terminals are removed,
the pressure control device is inserted into the grooves,
temperature sensor tubes are inserted into the cutout on the front of the casing,
further, the control device is slightly shifted into the groove so that the rear elements enter their grooves,
the device is screwed to the housing cover,
after that, according to the instructions, a step-by-step connection of all elements in the electrical circuit is carried out.

It is important to remember that the installation, connection and operation of the boiler should only be carried out by a certified specialist representative of the company. Otherwise, contracts for the provision warranty service are automatically cancelled.

After the installation of the boiler, all elements are checked for the presence of the proper degree of tightness. When checking, the control pressure on the burner reaches a value of 150 mbar.

Maintaining the set temperature without human intervention. Easy to clean and maintain. Non-volatile.

Model range (kW) 12, 20, 24, 25, 32, 45

The extraordinary popularity of Buderus Logano S111 solid fuel boilers is caused by the design of maximum automation of the boiler, without the participation of electricity, which significantly increased the comfort of operation in non-volatile heating systems. You don’t have to “stand” above it, the boiler will do everything by itself. All that is required of you is to put fuel on time 2 times a day and remove ashes as needed.

The steel solid fuel boiler Buderus Logano S111 has been developed since 1968, during which time a successful design with a semi-automatic principle of operation was obtained, using the natural laws of nature, such as the force of gravity and thermal expansion. Let's take a closer look design features this wonderful boiler.

Semi-automatic fuel supply

Vertical loading from above made it possible to automate the supply of fuel using natural gravity. As it burns, the fuel sags under its own weight into the combustion zone, supplying a new batch at the right time.

After kindling the boiler and entering the operating mode, you can fill in more raw coal or firewood, by the time it approaches combustion, it will already be dried and prepared for combustion, which increases the efficiency of fuel combustion. (This condition is applicable to boilers from 20 kW and above)

Burning time of one bookmark of fuel, up to 12 hours

The volumetric loading hopper increased the time interval required to load a new batch of fuel. You can approach the boiler literally 2 times a day, in the morning and in the evening, adding a new batch of coal or firewood and removing the ash if necessary.

High energy efficiency, up to 86%

The design of three-fold rounding of flat heat exchangers significantly increased the efficiency of heat transfer to water in the heating system. When passing through heat exchangers, hot flue gases have time to transfer heat and cool down to a temperature of 100 - 250 degrees, while in conventional furnaces the outlet temperature is about 600 degrees.

Refractory brick (chamotte) in the boiler structure

The fireclay refractory brick used in the construction of the boiler performs several functions. Laid in the place of direct contact with the burning fuel, it protects the colder heat exchanger (rate up to 100 degrees) from sticking of resin and slag, and also, when heated, prepares a new batch of fuel for combustion and completely burns out the unburned part in case of sticking.
The other part of the fireclay, located above the combustion zone, stops the hot gases going into the channels of the heat exchangers, which contributes to a better transfer of heat to the heating water.
And also, heating up, burns out the volatile substances released from the fuel during combustion, thereby achieving more complete combustion fuel.
For the combustion of gases, additional air is supplied to the hot fireclay zone through air channels arranged on the sides of the boiler. The air supply is regulated by special valves.

Energy efficiency is 26% higher than conventional boilers

As a result of the above solutions, the Buderus Logano S111 boilers have achieved high energy efficiency, with coal it was 84%, with wood 86%.

For example, the energy efficiency of high-quality boilers of classical design reaches only 60%.

Automatic temperature control

Opening and closing of the combustion air damper is carried out by an automatic temperature controller manufactured by the well-known company Honeywell USA. The principle of operation is based on the thermal expansion of a substance that is sensitive to changes in the temperature of the boiler water.
When the set temperature is reached, the valve reduces the air supply, when it falls, it increases, automatically opening and closing the air damper.
There is a scale on the valve that allows you to accurately set the required water heating temperature.
After setting the temperature, the valve maintains the temperature at the same level without human intervention. Adjustment range, from 60 to 95 degrees.
The valve also protects the boiler from boiling and overheating.
The air damper has a viewing window to control the combustion of fuel.

Shaking grate

The grate system designed in a special way will relieve you of the need to open the lid and turn the coals with a poker. To shake the grate, it is enough to slightly shake the lever located on the left side of the boiler. Ash and burnt residues will be collected in the ash box under the grate

Manufacturing quality.

German boilers Buderus Logano S111 are produced in Europe at the Czech plant Dakon, which is part of the international concern Buderus.
The special heat-resistant boiler steel used in the boiler design has a service life of at least 25 years.
