Buderus gas boilers have been on the heating equipment market for a long time. They have won worldwide recognition for their high quality, excellent technical characteristics and high working efficiency. Boilers are used in private houses of various 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 operating on electricity, solid and diesel fuel.
Gas boilers are most popular due to the prevalence and availability of raw materials. Depending on the installation, such devices are wall-mounted and floor-standing. They are produced with different power, there are devices with a load of more than 100 kilowatts.
Solid fuel models run on 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 the inflatable burner. The installed automation allows you to save on fuel and achieve the best heating mode.
Condensing-type devices have 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 combustion gases allows to reduce fuel consumption. Also, the emission of harmful substances from Buderus condensing boilers is significantly reduced.
Combined models that run on several types of fuel can be found on sale. 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 offered products of the brand can be classified according to different criteria. By the method of installation, they are distinguished:
- wall-mounted;
- floor.
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 W.
Wall mounted boilers
Wall-mounted models are often used for autonomous heating of an apartment. They are small in size, not inferior to the efficiency and productivity of floor standing devices. There are one or two contours. Apartment boilers have a low power - from 7 to 28 kW. All wall-mounted devices have a circulation pump, an expansion tank, a pressure gauge, a thermometer, an auto-control system, a heat exchanger, and a burner. The main advantages include diminutiveness, low cost.
Floor standing boilers
Floor-standing devices are available with an atmospheric or forced draft burner. The heat exchanger is made of cast iron, sometimes steel. They run on any fuel. The power of the boilers that are installed on the floor is high and reaches 95 kW.
The benefits include:
- lack of noise;
- smooth temperature control;
- the possibility of upgrading and installing additional devices;
- the ability to connect a tank for heating water with a capacity of up to 200 liters;
- continues to function at a pressure of 10 mbar;
- Ease of Management.
Large-sized floor-standing units are installed 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 carried out by a qualified specialist according to the instructions. Then it is necessary to obtain 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 owner of the equipment should be familiar with:
- Connection is only possible with corrugated pipes. They are approved for operation by Gostekhnadzor.
- The equipment is installed in a room that complies with SNiP and PPB standards.
- In the case of connection to a chimney, one pipe is installed per device.
Even if the user knows how to connect a gas boiler, it is forbidden to do it with his own hands. Not a single inspection service will allow you to start up gas equipment that is self-assembled.
Boiler selection by power
Long-burning boilers Buderus are produced in a wide range of capacities. According to this indicator, you can choose the optimal 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.
- House insulation. If the room is well insulated, less energy is required for heating.
- Climatic features. These include the average annual temperature, the length 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 rates are calculated for 1 sq.m. for different regions. For the middle band, it is optimal to use 100 W per 1 sq. M., For Siberia, 150 W / sq. M., For the Arctic region, 200 W / sq. M.
Features of a double-circuit boiler
In addition to heating the room, the boiler can provide the house with hot water. Devices with two circuits are:
- Flowing. Water heating is carried out in a flow-through mode. The device is small, and the water heats up immediately after opening the tap.
- Accumulative. 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 efficient and safe thanks to built-in sensors. Automation is responsible for temperature control. There is a filter for incoming water.
Review of popular Buderus models
Device Logamax plus GB072 happens with one and two contours. The model is capable of heating a room up to 300 sq.m. It has a built-in three-speed pump, error indicator, temperature sensors, a 12-liter water tank and a condensate drainage unit. The gas boiler can be operated with liquefied gas. Management is carried out automatically.
Single and double-circuit boiler Logamax plus GB112 is available with a capacity from 29 kW to 60 kW. Suitable for heating private houses and cottages, industrial enterprises, as well as terraced houses. The advantages include high efficiency, smooth power change, the presence of a built-in heat exchanger, the ability to install individual hydraulic circuits.
