User manual
The Buderus gas boiler is intended for use exclusively in closed systems hot water supply and heating. Any other kind of exploitation is considered as improper use. If the power cord is damaged, then it should be replaced by entrusting this matter to professionals, or rather, specialists service department. Otherwise, there may be dangerous situations when operating the device.
Regular Maintenance and follow-up examinations are prerequisite environmentally friendly and safe operation systems. The Buderus gas boiler must be installed in a room that is well ventilated, the air must be supplied regularly. exhaust and supply ventilation in no case should it be blocked or reduced, this applies to openings in walls, windows and doors. It is important to ensure that the requirements for the ventilation system are met during construction works, this may be, for example, the replacement of doors or windows. The air in the room where the equipment is supposed to be installed must not contain chemically aggressive substances and flammable vapors, as well as gases and dust.
It is unacceptable to store flammable and explosive materials such as solvents, gasoline, paper, and paint near the boiler. All substances that can cause corrosion must not be used and stored near the equipment. This should include adhesives and cleaning agents, solvents and other products that contain chlorine.
The Buderus Logamax U072-24K boiler must be operated under normal pressure water in the heating system, which can vary from 1 to 2 bar. If you need a higher operating pressure, then you should ask about it from the specialists of the heating company. Before filling the system with water, you need to find out where the tap for feeding the system is located. It is usually located at the bottom of the boiler, between the hot water and heating supply connections.
Conclusion
Buderus Logamax U072-24K, the instruction manual for which is supplied with the kit, must not be filled out cold water. In this case, damage to the boiler may occur. If water is poured into the heating system, then cracks may form on the hot heat exchanger of the equipment due to internal stresses.
A brand such as "Buderus" is one of the most famous in the world heating equipment. At the turn of the century this German company gained fame, mainly due to its reliable floor Buderus. Good feedback customers, specialists, German build quality have done their job, and now the Buderus brand is associated, first of all, with reliability and quality.
The only significant drawback was the rather high cost of such equipment. A few years ago, the company merged into a holding company with a no less famous German manufacturer, Bosch, to produce gas equipment, including in Russia (wall-mounted gas boilers are assembled in Engels, Saratov Region).
This allowed them to significantly reduce the price of their gas boilers and, as well as reduce the delivery time of equipment to outlets. AT last years the holding is also actively developing a new direction - these are wall gas boilers Buderus : double-circuit, single-circuit 12, 18, 24, 28, 35 kW.
In order to get an idea about them and decide whether the Buderus gas boiler is worth buying or not, you need to familiarize yourself not only with customer reviews and prices for them, but also with the technical characteristics and design of the device, consider the features and the lineup mounted boilers.
Having compiled some kind of operating instructions for ourselves, we will determine both the advantages and disadvantages of single-circuit and double-circuit gas boilers of the Buderus brand.
Gas boiler "Buderus Logamax U072"
Model range of gas boilers Buderus Logamax.
On the Russian market the company supplies wall-mounted (mounted) boilers of the Logamax series in double-circuit and single-circuit versions, among which there are several modifications.
1. Buderus Logamax U042 / U044
These are double-circuit gas boilers Buderus with a copper bithermic heat exchanger. They come with a closed combustion chamber U042 K, and with an open one - U044 K. They are produced with a power of 24 kW.
2. Buderus Logamax U052 / U054 K
Available in both double and single-circuit boilers rated power 24 and 28 kW. The productivity of domestic hot water for double-circuit models is 11 and 13 l / min., respectively. They have one bithermic heat exchanger made of high quality copper.
Marked as follows, U054 - boilers with open cam combustion, with a chimney diameter of 131 mm, U052 - with a closed chamber, i.e. turbocharged boilers. If the article “K” is added to the designation, this is a double-circuit boiler or combined, if it is absent, the boiler is single-circuit, only for heating.
3. Buderus Logamax U052 T / U054 T
Home distinctive feature these models is the presence in them storage boiler volume of 48 liters. It is used in houses with an increased need for hot water. They are produced with open and closed combustion chambers and a power of 24 kW.
4. Model boilers Buderus Logamax U072 the most popular and budget. We will dwell on them in more detail.
Unlike the models described above, this series has a wide power range: 12 kW, 18 kW, as well as 24 kW and 35 kW. They are produced in double-circuit and single-circuit versions, and only turbocharged ones - with a closed combustion chamber.
Boilers with forced draft can be used both under 60/100 mm and under a separate smoke exhaust and air supply system 80/80 mm.
Boiler control panel "Logamax U072"
Double-circuit gas boilers Buderus Logamax U072K with a capacity of 24 kW will give hot water 11-12 l / min, with a power of 35 kW - up to 16 l / min. If this indicator is important to you, then you should buy a gas boiler with a capacity of at least 24 kW. Boilers "Logamax U072-18" are designed more for heating a private house small area up to 130-150 m2.
The main distinguishing feature is the presence in gas boilers of the U072K series of two separate heat exchangers:
- main copper for heating the coolant in the heating system;
- secondary stainless steel for heating running water.
