Heating wall-mounted gas boiler Buderus: device, types (single-circuit and double-circuit), as well as models and reviews

European companies are considered recognized leaders among manufacturers of heating equipment.

They own all the most advanced developments and conceptual solutions in this area.

One of the leaders is] Buderus[/anchor], which will soon turn 300 years old.

Today it is part of the Bosch Thermotechnik GmbH holding, which significantly strengthens its position among its competitors.

Let's consider one of the company's activities - wall-mounted gas boilers.

Wall-mounted gas boilers Buderus

Buderus products are manufactured in several European countries. In Russia there is a plant in Engels, where, among other heating equipment, wall-mounted gas boilers are produced.

This makes it possible to produce installations that are fully adapted to the technological and climatic operating conditions in Russia, and it also becomes possible to reduce the cost of boilers for the end user.

The production uses advanced technical and design developments to ensure stability, durability and efficiency of components and parts. The main emphasis is on maximum automation of work, as well as ease of control and maintenance of the units.

A revolutionary system for optimizing boiler operation is used, taking into account external factors - additional heat sources, climatic conditions, etc.). It is possible to remotely control the operation of the system using a special application on a smartphone.

Types

There are different modifications of Buderus wall-mounted boilers.

By number of circuits:

• Single-circuit. They only provide heating of the coolant for the heating circuit.
• Dual-circuit. At the same time, they are capable of preparing domestic hot water and heating the coolant for the heating system.

By type of combustion chamber:

• Atmospheric (open) . The air required for the combustion process is taken directly from the room in which the boiler is installed. Removal of smoke and other combustion products occurs using natural stove-type draft.
• Turbocharged (closed) . The air is taken from outside and enters the boiler through the external pipe of the coaxial chimney. For this purpose, a turbocharging fan is used, which simultaneously ensures smoke removal.

For residential premises, it is more convenient to use turbocharged models, since natural draft is unstable and can be directed in the opposite direction by a strong gust of wind or a draft in the room.

By type of thermal energy transfer:

• Convection . A traditional scheme for heating the coolant in a burner flame without additional procedures was used.
• Condensation . A technique that appeared relatively recently. The liquid is preheated using thermal energy obtained by condensing water vapor from the exhaust smoke. The prepared coolant does not require intensive heating, which reduces gas consumption and softens the operating mode of the heating pad and heat exchanger. In total, this gives high efficiency (up to 108%, although this method of calculation is not correct and is a common marketing ploy), gas savings and an increase in the service life of the heat exchanger.

IMPORTANT!

Condensing models are able to fully operate only on low-temperature systems. If operating conditions do not allow the use of such modes, purchasing a condensing boiler will become impractical.

Main types of water heater breakdowns

Water heater pipe

Among the main types of malfunctions are the following:

• Scale on the heating element. It appears due to the fact that the anode, which is designed to protect against scale, fails. If it is not changed in time, it will lead to damage to the heating element. The appearance of a large amount of scale can also lead to overheating of the heating element and its breakdown.
• Clogged pipes. This comes from the intensive use of water and its quality. If the water contains a lot of mechanical impurities, this will affect the service life of the boiler. It is recommended to install special filters.
• Frequent power fluctuations can cause electronic systems to fail. Despite the fact that modern devices are equipped with fuses that simply turn them off during power surges, the latter can cause the boiler to break down.

In general, all malfunctions are associated either with improper installation of the boiler or with its improper operation. Therefore, in the first case, it is better to use the services of specialists. At the very least, they are responsible for their work, and the customer will not suffer financially if the installation is done incorrectly. In the second case, it is recommended to carefully read the operating instructions before starting to use the water heater.

Advantages and disadvantages

The advantages of Buderus wall-mounted boilers are:

• High build quality, reliability of units and parts of the unit.
• Easy to control, convenient display with intuitive symbols for operating mode adjustment controls.
• Possibility of remote control of the system from anywhere in the world.
• Compact, able to fit into the interior of a small kitchen.
• Relatively low cost compared to similar models from other companies.

There are also disadvantages:

• Boilers are energy dependent, require stable voltage, need to install stabilizers.
• Some parts are made entirely of plastic, which makes them short-lived under harsh operating conditions.

NOTE!

The disadvantages of Buderus boilers are not decisive and are completely offset by the undoubted advantages that all models have.

How to choose the right model

Combined tank-water heater Buderus

The selection of the optimal storage water heater model depends entirely on the degree and intensity of hot water consumption. For a large family (4 or more people), it is better to choose a large tank. On the other hand, a 120 liter design will also cope with this task. Models with a large tank volume (300 liters or more) are suitable for either very large families or guest houses with several bathrooms. A volumetric boiler will be able to provide them with an uninterrupted supply of hot water, even when used at the same time. For organizations and establishments, it is also better to choose an option with a volume of 300 liters or more.

The second criterion is cost. Here everyone must evaluate their financial capabilities and correlate them with the required performance of the device. There is no need to buy a boiler that will run idle, just because if it is more expensive, it is supposedly of better quality.

What series and models are wall mounted?

Buderus wall-mounted boilers are represented by one large Logamax line, which consists of 4 series:

• Buderus Logamax U042/U044 . Double-circuit installations with a power of 24 kW. Equipped with a bithermic heat exchanger, which allows you to simultaneously heat both the coolant and hot water. There are models with a closed (042) and open combustion chamber (044).
• U052 / U054 K. Single- and double-circuit boilers with an open (054) and closed (052) combustion chamber. For dual-circuit models, the designation contains the letter “K” (combined). Two models are available with a power of 24 and 28 kW.
• U052 T / U054 T . Model with a power of 24 kW, with an open or closed combustion chamber. A special feature is the presence of a 48-liter hot water storage tank, which allows you to meet high demands for hot water.
• U072 . The most popular series of turbocharged boilers with a capacity of 12, , and kW. Single and double circuit models are available. High demand is due to the relatively low cost of boilers. Equipped with two heat exchangers - primary (for coolant) and secondary (for hot water supply). The most popular boilers are 24 and 35 kW, producing up to 12 and 16 liters of hot water per minute, respectively. Capable of heating 240 and 350 m2 of residential, public or commercial areas.

When choosing a boiler, you should compare its characteristics with the size of the room and the family’s need for hot water. The manufacturer provides a choice for any conditions, which allows you to get the best option.

Range

Each type of Buderus boiler is represented by several models, differing in basic technical and functional parameters, including performance and dimensions.

Specifications

Let's look at the technical characteristics of Buderus wall-mounted boilers:

Device

The main components of Buderus wall-mounted boilers are:

• Gas-burner.
• Heat exchanger (bithermal or conventional type).
• Turbocharger fan.
• Circulation pump with automatic air removal.
• Secondary plate heat exchanger made of stainless steel.
• Three way valve.
• Control equipment for pump and fan operation.
• Control board with sensor system.
• Connecting pipelines, connecting pipes.

The coolant enters the primary heat exchanger, where it is heated to the maximum possible value.

Then it goes to the secondary heat exchanger, where excess heat is transferred to prepare hot water.

After this, in a three-way valve (mixing unit), it receives the set temperature by mixing a certain amount of colder return flow, after which it exits into the heating circuit.

All work is controlled by a system of sensors that send signals to the control board. The occurrence of problems is immediately detected, the owner is notified by displaying an error , and in difficult cases the boiler operation is blocked .

Operating and setting instructions

Operating Buderus boilers is not particularly difficult. All functions of the unit are simple, their adjustment is not difficult and is done using the corresponding buttons on the control panel.

The user does not perform any actions with the boiler, except for filling or draining the system.

A suitable tap or drain valve is used for filling. It must be remembered that adding cold water to a hot boiler is prohibited, otherwise the heat exchanger can be destroyed. After a long period of inactivity, it is necessary to carry out thermal disinfection.

The transition to summer or winter occurs at the user's request by changing and saving the mode on the control panel.

Installation and configuration of Buderus boilers must be carried out only by certified specialists from the service center, otherwise the warranty agreement will be considered terminated at the initiative of the owner.

What to pay attention to during installation?

Steel gas boiler Navien Ace

Since instructions are included with the equipment, there are no problems with installing and connecting the device. Doing it yourself is not a problem. Even a non-professional can understand the instructions. Moreover, it is written in Russian.

The only thing that experts ask you to pay attention to is the method of removing carbon monoxide. They can be discharged through a regular atmospheric chimney connected to the smoke exhaust system of the house or installed as a separate structure

But if you are not satisfied with any option, you can make a coaxial chimney. Its installation is several times simpler. But keep in mind that coaxial structures are used only when the heated area of ​​the house does not exceed 110 m². They can be installed with boilers whose power does not exceed 11 kW.

Price range

The price range for Buderus wall-mounted boilers is approximately 30-60 thousand rubles.

For top-level equipment, this slightly and significantly increases demand and relevance among users.

When planning a purchase, you need to check with your regional representative about the cost of the units and find out the amount of additional costs (warranty agreement, cost of additional equipment, etc.).

IMPORTANT!

An attempt to save money on concluding a warranty agreement will result in even greater costs for repairs or maintenance of the boiler.
