Viessmann boilers have good performance properties. The article describes correct installation and installation of boilers, which will allow you to realize their full potential and avoid troubles caused by installation errors.

Depending on the type, Viessmann boilers are installed differently. This is caused design features heating water heating unit, its dimensions, weight, method of connection to the chimney, type of fuel.

Installation steps for Viessmann boilers:

Installation various types boilers

• Solid fuel and gas floor-mounted.

These types of units are characterized by increased mass, slightly larger width, length and height. The devices need the strongest and most solid foundation, because their weight is the largest in the entire product line of the company. The base is made of rubble stone, broken brick, crushed stone, concrete. The area of ​​the foundation is three to four times the area of ​​the boiler. Usage weak foundation leads to damage to the chimney, loss of integrity threaded connections, leaks of coolant and household gas, fires, explosions. Poisoning is no less dangerous carbon monoxide. Solid fuel type heating devices are very demanding on the quality and size of the chimney. When burning wood, the release of volatile substances is greater than when burning gas, and the soot content in the emitted smoke is tens of times higher. Therefore, the diameter of the chimney channels must be increased. Minimum size channels is indicated in the operating instructions, but in reality it needs to be made at least one and a half times larger in order to avoid overgrowing with soot as a result of using oily or damp firewood. Incorrect calculations, installation and connection of Viessmann Visman boilers increase the risk of fire and carbon monoxide poisoning tenfold.

• Gas wall mounted.

Does not require a base because it is fixed to the wall using anchor bolts. Of all fuel boilers, it has the minimum weight and maximum efficiency.
Connecting the power supply system.

• A solid fuel heating water heating unit does not require a special power system.

The only requirement is a flood sheet that protects the floor from possible escape of coals and protects against fire.

• Gas boiler requires connection to the mains low pressure network gas. Prohibited by law

make this connection yourself. This is fraught with a gas leak, explosion, fire, and is dangerous not only for the people living in the house, but also for their neighbors. Connection to the gas pipeline must be carried out by specialists with appropriate education and documents of the established standard. After connecting the power, the technician will definitely search for and eliminate household gas leaks.
Connecting the heating system.
Installation of a Visman boiler to heating pipes is identical for any type and model. The pipes are connected using threaded connections sealed with fluoroplastic (FUM). A properly assembled connection will serve without leakage for decades. The water outlets of the unit are connected to metal-plastic pipes using adapters and fittings, and does not require special equipment. If the heating is made of plastic pipes, you will need a special soldering iron. Metal pipes heating is required welding machine, an angle grinder (grinder) and a highly qualified craftsman.
Chimney connection.
Solid fuel and gas boilers with an open chamber are connected to a chimney that extends above the roof ridge using pipes made of roofing iron. The use of galvanized steel pipes is unacceptable; when heated, zinc begins to be released into the air, leading to accumulation in the body and severe poisoning.

Installation and installation of Viessmann boilers must be carried out by specialists. This is a guarantee of safe and comfortable heating V winter period. The masters will determine the best place for the unit, optimal location and chimney shapes will be calculated required size and the shape of the foundation, calculate ventilation and fire safety premises. Don’t risk the lives of your loved ones for illusory savings.

Double-circuit gas boiler Viessmann Vitopend 100-W

Double-circuit gas boiler Vitopend 100-W German company Viessmann is great solution for organizing heating and supply hot water How small rooms (small apartments, small offices), and individual houses area up to 300 square meters. Due to the fact that the boiler is mounted on the wall, it saves effective area(especially in small apartments), but simple and attractive appearance will allow it to fit into any interior.

The advantages of this boiler include its compact size - I am still surprised by the fact that a unit with such small dimensions is capable of efficiently heating a room and uninterruptedly providing hot water. Another advantage is the control system - simple and intuitive, not requiring special skills from the user. In addition, the boiler is equipped with a self-diagnosis system, which greatly simplifies its operation and monitoring of its proper operation.

Viessmann specifically agrees specifications of its gas boilers, which are intended for operation in Russia, with the peculiarities of local gas supply.

Naturally, there are also disadvantages - high sensitivity to voltage changes in the electrical network and some operating features, which we will discuss below.

General view and technical characteristics

Double-circuit gas Viessmann boilers Vitopend 100-W comes in two types: chimney and turbocharged. The first ones will be connected to a stationary chimney made for the installation of boilers of this type (it provides natural cravings and removal of combustion products). Turbocharged boilers are installed in rooms where there are no special exhaust systems for exhaust gases: combustion products are removed using a special fan outside the room, which makes it possible to install such a boiler in almost any apartment. We will consider the chimney model.

In addition to the boiler, the delivery set includes a mounting frame and a pipeline for exhaust gases. The installation of the boiler and installation of the chimney system is carried out by qualified craftsmen, so in this matter you will have to rely only on the level of their professionalism.

The first start-up of the boiler and its adjustment is carried out by a representative service center Viessmann in your region, they also install the boiler under warranty.

Technical characteristics of the Viessmann Vitopend 100-W boiler:

• minimum and rated power - 10.7-23 kW;
• power of the hot water supply system - 23 kW (this boiler has priority for hot water supply, therefore, when this circuit is turned on, all boiler resources are directed to heating water);
• maximum water pressure in the system is 3 bar;
• expansion tank - volume 6 l;
• maximum permissible temperature- 85 °C;
• water temperature range in the heating circuit is 40-80 °C;
• temperature range in the hot water supply circuit - 30-57 ° C;
• minimum and maximum productivity in the hot water supply circuit at an average water temperature of 30 °C - 2.4-11 liters per minute;
• smoke formation temperature - up to 117 °C;
• electrical protection class - IPX4D;
• overall dimensions (width, height, depth) - 40x72.5x34 cm;
• weight - 36 kg.

Control Panel

From left to right: pressure gauge, display, hot water temperature regulator, heating water temperature regulator, switch

The pressure gauge shows the water pressure in the heating circuit. After the heating system is installed (radiators, heated towel rails, heated floors are installed), the circuit must be filled with water. For these purposes, a special key is used that opens the water intake into the boiler heating system.

When filling the system with water, you need to look at the pressure gauge so that the water pressure does not exceed 1.5 bar: this is what the manufacturer recommends. But, for example, I brought the pressure in the system to 2 bar, and after some time (two weeks the boiler did not turn on - I connected the gas, agreed on after-sales service) it dropped to the recommended 1.5 bar - air left the system through special valves on the batteries and in the boiler itself. When the heating circuit operates, the water will heat up and the pressure will rise to the normal operating value of 1.8-2.5 bar.

The display shows the temperature of the water in the heating system, the temperature of the hot water, the intensity of the burner, and can also show fault or error codes that are deciphered in the user manual.

The illustration above shows that hot water heating is turned off; on the left, at the bottom of the display, the “light” shows that the water in the heating system is being heated (in the “house” the battery icon is lit) and its current temperature.

With the help of temperature regulators, you set the required level according to your desire - everything is very individual here. You just have to try several options and settle on the one that suits you. In any case, the regulator should be between marks “2” and “5” - in the lower position there will not be sufficient heating, and in a position greater than “5” there is a risk of overheating. Please note that to warm up the room for desired temperature it is necessary to set the water temperature in the system above 60 °C (the position of the regulator is above the “3” mark).

Since the boiler has priority for preparing hot water, it is equipped with a special relay that is activated when the hot water tap is opened: the burner turns on, and a special three-way valve switches to the hot water preparation mode.

Attention! If you do not use hot water regularly (do not live in an apartment, are away for a long time), from time to time you should turn on the hot water circuit and release a few liters - to prevent the three-way valve from working properly (so that it does not “sour”).

Optional equipment

The Viessmann Vitopend 100-W boiler can be equipped with additional devices that will greatly simplify its operation.

Vitotrol 100 RT is a room thermostat on which you set the desired temperature in the room, and it takes over all control of the boiler.

Vitotrol 100 UTA - more complex model thermostat, allows you to program temperature conditions throughout the day. For example, you can program it so that at night the temperature will be maintained at, say, 17 °C, and by the time you wake up at 7 am it will already be 21 °C. In the same way, during the working day, when there is no one in the apartment, the air temperature can be lowered, and when you arrive from work, the thermostat will raise it to the most comfortable level.

Vitotrol 100 UTDB is an even more sophisticated device, equipped with a liquid crystal display to indicate operating modes.

Vitotrol 100 UTDB-RF - this gadget has a device for receiving and transmitting radio signals, with its help temperature regime indoors can be installed remotely.

Tips for use

It is imperative to check that the gas hose is connected to the boiler without distortions or mechanical stress. It goes without saying that there should be no gas leaks.

When the technician from the service center was preparing for the first start-up of the boiler, he used a special highly sensitive device to check for gas leaks. And it turned out that almost all joints were leaking - a little, not significantly, but they were leaking (when checked with a soap solution, no leaks were visible). We had to call gas workers, who re-packed all the connections.

In order to promptly respond to possible gas leaks, I recommend purchasing a household gas analyzer (without one, they may not even supply gas to your apartment). Issue price $20. The device is installed at a height of 20-30 centimeters above the boiler and if there is a gas leak, it will give a rather unpleasant sound signal, which will be very difficult not to hear (you can check it using gas from a simple lighter).

In order to extend the life of the boiler and its combustion chamber, it is necessary to install gas filter- the gas pipeline may contain small abrasive particles (sand and other debris) that can clog the combustion chamber, which will certainly affect its normal operation. Such a filter costs up to $10, and you can clean it yourself - remove the front cover and clean the foam filter, which is located between two metal mesh. After cleaning, make sure the cap is screwed on tightly and there is no gas leakage.

The electronics in the Viessmann Vitopend 100-W boiler are very sensitive to voltage drops, so I strongly recommend purchasing a voltage stabilizer. Firstly, it will ensure normal and uninterrupted operation equipment, and secondly, it will save your nerves and money - warranty obligations do not apply to boiler failure due to a power outage (you can only sue the energy supply company, and you yourself know how this will end in our realities).

I purchased such a voltage stabilizer for $40, which, you see, is not much compared to the cost of the boiler or how much it might cost to replace the electronics. The output stabilizer "iron" provides 220 V and works normally when the input is from 140 to 250 V. It is designed for a power of 500 W, which is quite enough for one boiler.

If you have a coarse water filter installed and water enters the boiler through it, then it is better to choose a mesh (mesh size from 5 to 50 microns) as the filter cleaning element. You should avoid using a thread filter or any other filter, the smallest parts of which over time can get into the heater and impair its performance.

After the first start-up (let the boiler run for a day and turn it off), I also recommend cleaning the return filter. To do this, turn off two taps (upper and lower), unscrew the lid and clean the filter mesh from possible debris that got into the heating system during its installation.

An important point - when turning off the boiler, first turn the temperature controls to the extreme left position, let the boiler run for several minutes (so that the temperature in the heater drops) and only then turn off the power supply.

If you are going to close the boiler in a cabinet or build it into furniture, then you should take into account that its body can be removed “upwards”. Therefore, it is necessary to leave a distance of about 20 centimeters between top part boiler and furniture elements so that servicing can be carried out.

For normal operation of the boiler, an air flow is necessary, so it is strictly forbidden to close the special openings intended for this.

In the room where the boiler is installed there should not be high humidity for a long time - do not dry clothes in the same room as this appliance.

It is very important to properly ventilate rooms when the boiler is running. To do this, before opening the window, completely close the thermostatic valves on the radiator. Such actions will save gas and electricity.

When ventilating, set the regulator to “snowflake”

Another serious point is that batteries and thermostatic valves for normal operation should not be closed or cluttered (with heavy curtains or foreign objects).

Also, to save money, you should maintain the room temperature at the same level (20 ° C is considered optimal) - the boiler will operate stably, consuming gas and electricity evenly.

If you have blinds or shutters, you can close the windows at night to reduce heat loss.
