The gas boiler is the heart of the heating system. Not only home coziness and comfort of your household depends on a reasonable choice of gas boilers, but ultimately the family budget in the form of subsequent monthly payments for gas. In this article, we will try to offer the best solutions for different living spaces. Which gas boiler is better? Should you opt for a single-circuit version, or still give preference to a double-circuit boiler? Buy a solid, floor-standing gas boiler, or will a compact wall-mounted one be enough? We will try to find answers to these and many questions.
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 conditions of work in Russia, and it also becomes possible to reduce the cost of boilers for the end user..
In production, advanced technical and design developments have been used to ensure stability of operation, durability and efficiency of units and parts. The main emphasis is placed on maximum automation of work, as well as on simplicity of control and maintenance of the units.
A revolutionary system for optimizing the operation of the boiler 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 in a smartphone.

Types
There are different modifications of Buderus wall-mounted boilers.
By the number of contours:
- Single-circuit. Provide only heating of the heating agent for the heating circuit.
- Double-circuit. At the same time, they are capable of preparing hot water supply 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 where the boiler is installed. The removal of smoke and other combustion products is carried out using the natural draft of the furnace type.
- Turbocharged (closed)... The air is taken from outside and enters the boiler through the external pipe of the coaxial chimney. For this, a turbocharger fan is used, which at the same time ensures the removal of smoke.
For residential premises, it is more convenient to use turbocharged models, since the natural thrust is unstable and can be directed in the opposite direction by a strong gust of wind or a draft in the room.
By the type of heat transfer:
- Convection... The traditional scheme of heating the coolant in the burner flame was used without additional procedures.
- Condensing... A technique that has appeared relatively recently. Preheating of the liquid is applied using thermal energy obtained by condensing water vapor from the exhaust smoke. The prepared heat carrier does not require intensive heating, which allows reducing gas consumption and softening the operating mode of the heater and heat exchanger. In total, this gives a 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 life of the heat exchanger.
IMPORTANT!
Condensing models are capable of fully functioning only on low-temperature systems. If the operating conditions do not allow the use of such modes, the purchase of a condensing boiler will become impractical.

Device
The main units of Buderus wall-mounted boilers are:
- Gas-burner.
- Heat exchanger (bithermal or conventional type).
- Turbocharger fan.
- Circulation pump with automatic air venting.
- Secondary stainless steel plate heat exchanger.
- Three-way valve.
- Pump and fan control equipment.
- Control board with sensor system.
- Connecting pipelines, connecting pipes.
The heat carrier enters the primary heat exchanger, where it is heated to the maximum possible value.
Then it enters the secondary heat exchanger, where excess heat is transferred to the preparation of hot water.
After that, in a three-way valve (mixing unit), it receives the set temperature by mixing in a certain amount of a colder return flow, after which it enters the heating circuit.
All work is monitored by a system of sensors that send signals to the control board. The occurrence of malfunctions is immediately detected, the owner is notified by displaying a code on the display mistakes, and in difficult cases, the boiler operation is blocked.
Operation and setup instructions
The operation of Buderus boilers is not very difficult. All functions of the unit are simple, their adjustment is not difficult and is carried out 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 long periods of inactivity, thermal disinfection must be performed.
The transition to the summer or winter period occurs at the request of the user by changing and saving the mode on the control panel.
Installation and adjustment of Buderus boilers should 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..
