Double-circuit gas boiler Viessmann Vitopend 100-W
The Vitopend 100-W double-circuit gas boiler from the 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
Dual-circuit gas boilers Viessmann Vitopend 100-W comes in two types: chimney and turbocharged. The first will be connected to a stationary chimney designed for the installation of boilers of this type (it provides natural draft 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 performance in the hot water circuit at average temperature water at 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 several liters - for prevention normal operation three-way valve (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 - room thermostat, on which you set the desired temperature in the room, and it takes over all control of the boiler.
Vitotrol 100 UTA is a more complex thermostat model that 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
You definitely need to check that gas hose was 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 the connection points were leaking - a little, insignificantly, 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 of the equipment, and secondly, it will save your nerves and money - the warranty does not cover the failure of the boiler due to a power outage (you can only sue the energy supply company, but how will that end? in our realities, you know yourself).
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 water filter installed rough cleaning and water enters the boiler through it, then it is better to choose a mesh as the filter cleaning element (mesh size from 5 to 50 microns). 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 the top of the boiler and the 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.
Popularity gas heating is growing more and more every year. One of the reasons for this growth is the cost of fuel, which serves as its basis. In addition, there are other advantages - simplicity and ease of use, there are no additional expenses for the maintenance and use of such equipment, greater efficiency in work, productive heating. Read what they are and what their advantages are.
Connecting the Viessmann boiler
Installation and connection gas boiler is produced in several stages. But before we start installation work All work related to the electrical connection must be completed.
And yet, the first launch should be carried out together with specialists who will once again check the entire system and give an opinion. Without the help of gas workers, it will be impossible to obtain permission from special authorities to use such equipment.
Even in case of the slightest deviation from the norms, you cannot turn on the boiler!
After examining the equipment, specialists will give advice and help you adjust everything correctly. This device is inherently dangerous and improper use may result in death.
Viessmann boiler maintenance
In order to avoid overhaul boiler and its complete replacement, it is necessary to follow the operating rules gas equipment. Even with the slightest and insignificant violations, you cannot try to correct anything on your own. Such actions can lead to additional violations and breakdowns and will only further worsen the technical condition of the gas boiler. In any case, you need to contact gas specialists.
Most best option- conclude an agreement for regular Maintenance boiler
Viessmann boiler repair
No matter how reliable Viessmann equipment is, sooner or later breakdowns still occur, parts fail, and spare parts wear out. Repairs are simply inevitable. In order to be able to carry out repairs in a timely manner and in the shortest possible time, it is necessary to take into account the possibility of free access even at the planning stage.
There must be free space around the device to be able to visually observe the operation of the unit. And in the event of a breakdown, repairs can be carried out quickly and without financial loss. Also, this approach will avoid dismantling the boiler and the inevitable costs in this case.
Spare parts for Viessmann boilers
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. Using a weak base leads to damage to the chimney and loss of integrity threaded connections, coolant leaks and domestic 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.
- A gas boiler requires connection to a low pressure mains gas line. 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 master in mandatory will search for and eliminate domestic 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, angle grinder (grinder) and highly qualified masters
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 the shape of the chimney, calculate the required size and shape of the foundation, calculate ventilation and fire safety premises. Don’t risk the lives of your loved ones for illusory savings.
The German company Wissmann has been one of the world leaders in the heating equipment market for several decades. The company gained its fame primarily thanks to its solid fuel and gas floor-standing boilers. And in this segment, perhaps, they have no equal at all.
IN last years The German concern is increasingly relying on compact and economical wall-mounted Viessmann gas boilers. Reviews for this type equipment is not as common as, for example, popular boilers of the brands or.
This is understandable, because the equipment is from German manufacturer has never been budget-friendly, and the price of wall-mounted single-circuit and double-circuit gas boilers Visman did not allow them to be purchased and made available to the average buyer.
Today we’ll talk in more detail and review the wall-mounted gas appliances of the widespread Viessmann Vitopend 100-W WH1d series. Thanks to the operating instructions, we will together determine their significant advantages and disadvantages compared to competitors, and consider the main types and technical characteristics of German boilers of this brand.
Main types and models of wall-mounted gas boilers Visman
Today, the German concern produces two main types of wall-mounted devices:
1. Traditional boiler models Viessmann Vitopend 100-W;
2. Condensing boilers Viessmann Vitodens 100(-200)-W.
Gas boiler Viessmann Vitopend 100-W
To countries Western Europe a German company supplies condensing gas boilers of the model Viessmann Vitodens. In Russia this type equipment is not so popular due to its high price of 100 thousand rubles and above. These devices have very good indicator Efficiency (more than 100%), and the country of origin is Germany.
For Russia and the CIS countries, this company has developed a more budget-friendly series of wall-mounted gas boilers Viessmann Vitopend 100-W. These models are characterized by a standard (for wall-mounted units) efficiency indicator of about 90%, and the price for a boiler is more realistic for the consumer - from 700 euros, which is already noticeably lower than, for example, for the same “”.
Boilers of the Viessmann Vitopend 100-W series are assembled in Turkey and in some countries of Eastern Europe, they are available in several versions:
— double-circuit with thermal power of 22, 24 and 30 kW;
- single-circuit with a power of 24 and 30 kW.
Depending on the type of combustion product emissions, gas boilers are divided into devices:
- With closed camera combustion or “turbo boilers”, with separate (80/80 mm) and, i.e. “pipe-in-pipe” type (60/100 mm);
- with an open chamber or “atmospheric” boilers, with a chimney pipe diameter of 130-140 mm.

Single-circuit and double-circuit gas boilers Viessmann Vitopend 100-W have built-in weather-dependent automation. If you additionally buy an outdoor temperature sensor, the boiler will operate taking into account the weather and air temperature outside the window, on the street.
Moreover, to maintain required temperature air in the house, it is possible to install a room thermostat for the Visman boiler. The company produces several types of these control devices under the name “Vitotrol”:
— mechanical thermostat type “RT”
— programmable type “UTA”
— with digital display “UTDB”
— with a built-in receiver and remote radio transmitter “UTDB-RF”
Kit for connecting underfloor heating to a Viessmann gas boiler
To connect the underfloor heating system, the company has developed a special kit.
It consists of the following elements:
- circulation pump;
- thermostatic mixing valve;
— thermal heads with a remote sensor;
— supply copper fittings.
This set automatically maintains the temperature required for a heated floor and prevents the formation of condensation in the boiler.
Having purchased such an installation kit for a Wiesmann boiler, you no longer have to purchase an expensive manifold group with a pumping and mixing unit for heated floors.
Technical characteristics of double-circuit gas boilers Viessmann Vitopend 100-W
Double-circuit (combined) boilers of the Visman brand have a hot water capacity of 10 to 14 l/min, depending on the power of the specific model.
