Wall-mounted gas boiler is capable of ensuring a house of hot water, and warm the air indoors. We tell about the main types and models of the device that will help you feel comfortable, and at the same time save gas.
The popularity of modern wall boilers is explained by the principle of "all in one", that is, the wall model already contains inside all the necessary nodes (burner, heat exchanger, expansion tank, pump, security and management system) and, in fact, is a mini-boiler assembly.
First level

| Comfort | ★☆☆☆☆ |

| Equipment | One-connecting boiler |
The simplest heating system consists of a wall-mounted one-mounted boiler and is the most fiscal way to solve the issue of heat inside the premises, covering the basic need for it in the apartment, in the country or in a country house.
This establishes a standard one-connecting boiler (for example, Bosch Gaz 6000). Burning the gas, it heats the coolant, most often ordinary water, and with the help of the built-in pump, it serves it in heating radiators.
Setting up the boiler is also extremely simple. You specify the temperature to which the radiators need to be heated, for example 60 ° C. And the boiler gives water in the feeding line of the appropriate temperature.
However, due to the lack of any feedback between the boiler and the premises, which he heats, the automation is not able to independently adjust the microclimate. The equipment does not know what is happening in the room. Therefore, if on the street suddenly sharply warmly, then the tenants will have to go to the boiler, twist the knob of the regulator and reduce the temperature or open the windows, and this is noticeably affected by fuel consumption.
Another minus will be the absence of hot water. Thus, this system according to modern standards is sufficiently primitive from the point of view of both comfort and gas savings.

Following the need to damn the house there is a matter of hot water supply. When it is warm in rooms, only cold water flows in the crane, it is possible to live, but there is no speech about the comfort.
Installing a double-circuit boiler (Bosch Gaz 6000 K) will help to solve the issue of hot water (Bosch Gaz 6000 K). The difference in price between them is minimal. The difference is that another heat exchanger is built into a double-circuit boiler, which heats the water for household needs, - the rest of the design is similar.
The principle of heating in this case flowing, that is, water heats up immediately before its supply to the crane (approximately as in the gas column). Hence the main minus of such a heating scheme is a limited hot water consumption associated with a relatively small wall-mounted boiler. If someone takes a shower, and at that moment you decided to wash the dishes, then the one who is in the soul will instantly feel the change in the water temperature.
Nevertheless, your basic need for warm and hot water will be satisfied.

| Equipment | Two-kotel Temperature regulator |
In the heating systems described above, the boiler simply warms the water to the desired temperature and sends it to the radiators. That is, you control the temperature of the radiators, and not the air temperature in the room. To control the air temperature, you must approach the boiler and adjust the heating temperature of the radiators manually. About any comfort is not talking. If you are wrong - it will be hot or cold, and so until you find the optimal temperature. Then the evening comes, it turns out on the street - and the setting will have to be re-made. When you get bored, you just put the temperature higher and open the window, and this will lead to increased gas consumption, as you will warm the street.
Let's try to improve the heating system to improve the convenience and saving gas. It is easy and inexpensive. The task is solved using a room temperature regulator - a device installed in a room that controls the actual temperature inside and automatically changes the boiler operation mode.
After installing this device, the boiler determines what happens in the room, and you no longer need to constantly adjust the temperature of the radiators manually. Instead, it is enough to set the necessary temperature on the regulator, and everything else will do it myself. When the actual temperature deviations in the rooms from the selected automation will send the boiler to strengthen or weaken the heating of the coolant.
In addition to directly improving the comfort of tenants, the dynamic regulation of the boiler modes saves fuel.
The Bosch GAZ 6000 Series Wall Boilers can use CR10 and CR50 luminous regulators. The second is different from the first thing that, in addition to maintaining the required temperature in the room, allows you to ask its weekly schedule. So, on a weekday afternoon, when there is no one in the house, you can set the temperature not 22, and 17 ° C. The systems of the house from temperature changes are not affected, and the gas consumption will noticeably decrease. By the time, when all the household returns, the air inside again warms up to the usual 22 ° C.

After the operation of the heating system is optimally adjusted by the room temperature, it is time to return to the issue of hot water supply. So that in all the cranes in the house there was enough hot water, the flow system changes to the cumulative, that is, we will heat the water not at the time of necessity in it, but in advance. To do this, the boiler is connected to the boiler (Bosch Wstb, Wst), in which a certain supply of water heated to the required temperature will be stored.
The volume of the tank directly depends on the number of residents and the intensity of the cost of hot water. Thus, the family of four capacity for 200-300 liters will be enough to satisfy all the need for hot water, regardless of the water treatment regimen.
Important! Before buying a cumulative water heater, make sure that the model of your boiler supports the connection function of an external tank
Bosch GAZ 6000 single-mount boilers are already prepared at the factory for use with an external tank. You need to connect the tank to special boiler fittings, connect the water temperature sensor in the tank to the boiler - and the boiler will determine what temperature there. If it decreases (you turned on the faucet and wash, for example), the automation will redirect the flow of the coolant instead of radiators into the tank, thereby heating the water there.
The fourth level heating system is able to meet the needs of most users and will allow you to completely abandon interference with the work of the equipment and get comfortable heating and hot water supply.

At the fifth level of the upgrade system, options that increase costs are added.
The standard temperature controller varies on an advanced modification with the control function of the heating system along the outer temperature CW100.
This room regulator, as well as previous models CR10 and CR50, maintains the air temperature in the room, has a weekly program. But also you can connect the outdoor temperature sensor.
With it, the heating system receives another feedback line. And depending on what the weather on the street is, the mode of operation of the heating equipment will change. For example, if on -25 ° C, then to maintain inside a comfortable 22 ° C, your heating system needs to heat the radiators up to 60 ° C. When the temperature on the street rises to -5 ° C, radiators will only heat up to 50 ° C *. This gives additional fuel economy and a more uniform mode of operation of the boiler, which will increase its service life.
The final line in matters of fuel economy - replacing the traditional boiler for condensation (for example, Bosch Condens 2500 or Condens 7000i). Its principle of operation reduces gas consumption by 5-7%. In short, the essence of the work lies in a deeper selection of heat from the combustible gas, that is, in a higher efficiency.

The maximum level of improvement of the heating system is an arrangement in a system of a system with several heating circuits.
For example, you need different temperatures in the rooms: 22 degrees in the living room, 19 in the bedroom and 25 in the nursery. So that it becomes possible, for the heating of each room must respond its separate outline and a separate temperature controller. A collector and several pumps are connected to the boiler, which will be supplied to the coolant in different rooms with different temperatures and intensity. Moreover, it is allowed to use various types of heating - in some rooms you can hang usual radiators, in others it is organized warm floors.
To manage such a system, the CW400 system control unit will also need, which performs the functions of the central brain of the entire system.
Because of the special complexity and the volume of work on the installation of multi-mounted heating, it is more expedient to lay a similar system at the design stage, before the start of major repairs. Otherwise, the alteration of the old heating system will turn into significant costs.
Bonus level
If you connect a CT100 remote control module to the system (for condense boilers Condens 2500 and 7000i), heating control will become even more convenient: you will get access to all the functions of the equipment via the Internet.
Download the mobile application, and it will allow from any point of the planet to monitor the state of the system, set the heating modes, change the individual temperature parameters and instantly receive non-recovery notifications.
Conclusion
Modern heating equipment due to the implemented modularity principle allows you to organize any system in the apartment, cottage, cottage or house - from a simple on the basis of one boiler to super tech using multiple contours, programmable regulators and control over the Internet.
Regardless of which level of complexity and promotion of the heating system, you will prefer, first of all it is important to choose equipment from a reliable and verified supplier. Only in this case can be guaranteed compatibility of all system components and their long and efficient operation.
