Buderus gas boilers have long been on the heating technology market. They have gained worldwide recognition due to their high quality, excellent technical characteristics and high work efficiency. Boilers are used in private houses of different sizes.
Varieties of boilers
The German company Buderus, now owned by Bosch, appeared in 1731. In 2004, the company's products also entered the Russian market. The main part of the equipment is gas heating equipment, as well as devices powered by electricity, solid and diesel fuels.
Gas boilers are most popular due to the prevalence and availability of raw materials. Depending on the installation, such devices are wall and floor. Available in different capacities, there are devices with a load of more than 100 kilowatts.
Solid fuel models work from coal, firewood. They have high efficiency, require inexpensive fuel and have autonomy.
Diesel boilers run on liquid fuel. Their power can reach 19 megawatts due to an inflatable burner. Installed automation allows you to save on fuel and achieve the best heating mode.
Condensation-type devices have an increased efficiency due to the use of energy from combustion products. Their principle of operation is based on the use of energy losses for heating the coolant. The energy of the combusted gases reduces fuel consumption. Buderus condensing boilers also significantly reduce the emission of harmful substances.
On sale you can find combined models that run on several types of fuel. For example, devices powered by firewood and electricity. If it is impossible to use one type of raw material, you can heat the product with another.
Device classification
All products offered by the brand can be classified according to various criteria. The installation method distinguishes:
- wall mounted;
- outdoor.
By design, one and two-circuit models can be distinguished, with a closed and open firebox, with a cast-iron or steel heat exchanger, as well as with natural or forced draft.
The manufacturer produces boilers with different capacities. It varies in the range of 7000-100000 watts.
Wall mounted boilers
Models that are mounted on the wall are often used for autonomous heating of an apartment. They are small in size, not inferior to the efficiency and productivity of outdoor devices. There are one or two circuits. Apartment boilers have a small capacity - from 7 to 28 kW. All wall-mounted devices have a circulation pump, an expansion tank, a manometer, a thermometer, an automatic control system, a heat exchanger, and a burner. The main advantages include miniature, low cost.
Floor boilers
Floor-mounted devices come with an atmospheric or pressurized burner. The heat exchanger is made of cast iron, sometimes made of steel. Work from any fuel. The power of boilers that are installed on the floor is high and reaches 95 kW.
The benefits include:
- lack of noise;
- smooth adjustment of temperature;
- the ability to upgrade and install additional devices;
- the ability to connect a tank for heating water with a capacity of up to 200 l;
- continues to function at a pressure of 10 mbar;
- Ease of Management.
Large-sized floor installations are mounted in large private houses.
Features of the installation of gas boilers
Gas heaters are often used due to the availability of fuel and ease of installation. According to safety rules, the first setup, connection and start-up is performed by a qualified specialist according to the instructions. Then you need to get permission to operate the device. All maintenance and troubleshooting work is also carried out by a dedicated service. The user can only correct minor problems on his own. But there are a number of requirements that the equipment owner should be familiar with:
- Connection is only possible with corrugated pipes. They are approved for use by the State Technical Supervision Service.
- Installation of equipment is carried out in a room that complies with the norms of SNiP and PPB.
- In the case of connecting to the chimney, one pipe is installed on one device.
Even if the user knows how to connect a gas boiler, do it yourself is prohibited. Not a single inspection service will allow to start gas equipment, which is mounted independently.
Boiler selection by capacity
Buderus long-burning boilers are available in a wide range of capacities. According to this indicator, you can choose the best device for heating any area. When choosing, the following factors are taken into account:
- The area of the heated room. The larger it is, the more powerful the unit will be required.
- Features of the walls. Thickness, material, thermal insulation.
- Warming at home. If the room has good thermal insulation, less energy will be required for heating.
- Climatic features. These include the average annual temperature, the duration of the cold season, and humidity.
- The number of windows, their size and type.
- The presence of ventilation.
- Additional functionality. A device that will heat water or food will require more power.
To simplify the choice of power, the norms per 1 sq.m. for different regions. The use of 100 W per 1 sq.m. is optimal for the middle band, 150 W / sq.m for Siberia, and 200 W / sq.m for the Arctic.
Features of a double-circuit boiler
In addition to the function of heating the room, the boiler can provide the house with hot water. Devices with two circuits are:
- Flowing. Water is heated in flow mode. The device is small in size, and the water is heated immediately after the tap is opened.
- Cumulative. The boiler is equipped with a boiler in which water is heated. This is an economical option with more massive equipment.
The most famous devices with two circuits include Legomax u972 183a. This mini boiler room is characterized by efficiency and safety due to built-in sensors. Automation is responsible for adjusting the temperature. There is a filter of incoming water.
Overview of popular Buderus models
Device Logamax plus GB072 happens with one and two circuits. The model is able to heat a room with an area of up to 300 sq.m. It has a built-in three-speed pump, an error indicator, temperature sensors, a 12 liter water tank and a condensate drainage unit. The gas boiler can run on liquefied gas. Management is carried out automatically.
Single and double circuit boiler Logamax plus GB112 available with power from 29 kW to 60 kW. Suitable for heating private houses and cottages, industrial enterprises, as well as ordinary houses. The advantages include high efficiency, a smooth change in power, the presence of a built-in heat exchanger, the ability to install individual hydraulic circuits. The smoothness of power control is carried out by a special pump with a gradual change in performance. It has a low noise level.
Gas condensing floor boiler Logano plus GB312 has a power of 90 to 280 kW.It features a compact size and increased efficiency. It incorporates a modulated gas burner. The Buderus gas boiler has a reduced emission of harmful substances into the atmosphere, convenient automatic control and no need for water circulation.
For heating apartments and private houses use a gas wall boiler Logamax U072 with a power of 18 and 24 kW. This is a compact device that runs smoothly during surges in water and gas pressure. It is protected against freezing and has a low noise level. The presence of errors can be judged by the LED indicator.
A popular electric boiler is Logamax e213 with power from 4 to 60 kW. It is used for heating apartments, houses and other objects. The boiler is small in size and runs silently. Since harmful substances are not emitted, it is not necessary to conduct a chimney channel. The electrical device can be connected to any heating system.
