Gas boilers Viessmann Vitopend 100-W
Wall-mounted gas boilers Viessmann Vitopend 100-W are a series of units designed for heating small and medium-sized premises. The best use case is apartments, residential buildings, office, commercial or public spaces up to 340 m2.
The peculiarity of this series is a relatively low cost with full functionality and capabilities of the boilers.
It is possible to connect an external temperature sensor, which provides adjustment of the operating mode depending on the air temperature outside. It is possible to independently heat domestic hot water, or connect an external boiler, if necessary.
The electronics of the boiler has a built-in timer, with which you can program the operation of the installation for a week in advance. The low noise level and the absence of extraneous odors make the use of boilers in residential premises safe and comfortable.
Varieties
It has already been said above that boilers of this manufacturer can be chimney and turbocharged. In addition, they are subdivided according to several criteria. Boilers can be double-circuit and single-circuit. Their fundamental difference lies in the number of contours, which follows from the name. That is, a single-circuit boiler is primarily responsible for heating the room, and a double-circuit unit heats water for both heating and domestic needs. But in the presence of a single-circuit boiler, the problem of hot water can be solved by installing an indirect heating boiler.
Boilers can also be traditional or condensing. The principle of operation of a traditional boiler is quite simple - the products of combustion heat the water and evaporate through the chimney. But the principle of operation of a condensing boiler is much more complicated - in this case, the combustion products condense, that is, they turn into a liquid. In itself, the device of such a boiler is much more complicated. Also, such a boiler has a coaxial chimney, which consists of two pipes of different diameters that are inserted one into the other.
One of the most famous is the boiler model Viessmann Vitopend 100 WH1D 263.
This option has a fairly decent power - about 32 kW. This is a double-circuit boiler, which is used both for heating the house and for supplying hot water for domestic needs. The combustion chamber of this boiler is closed. The tank of the device has a large volume - 10 liters, as well as a powerful circulation pump with a safety valve. Such a boiler is guaranteed to heat the water to almost 80 degrees, and in a very short time. The price of this boiler varies within 45 thousand rubles.
Another gas boiler is Viessmann Vitopend 100 WH1D 513.
The heat exchanger of this boiler is divided into two parts. One of them is made of high-quality copper, and the second is made of stainless steel. Such separations are called "primary" and "secondary" heat exchangers. The power of this unit is high - 33-35 kW. This is a single-circuit boiler, which is designed for heating. The approximate price will be 36-38 thousand rubles.
The next model is a boiler Viessmann Vitopend 100-W A1HB
, which has a power of 24 kW. The boiler is single-circuit. This is a simple and convenient model with a high-quality chimney system, small dimensions and low noise level. The boiler is able to heat water up to 80 degrees. The chimney diameter is 60/100. This is an excellent choice for heating a private house with a decent level of efficiency. The price for such a boiler will be approximately 39-40 thousand rubles.
Overview of Viessmann Vitopend boilers with closed and open combustion chamber
If you have an atmospheric boiler with an open combustion chamber in front of you, then its operation will be distinguished by natural draft. Some consumers deliberately refuse such equipment, and here's why. For fuel combustion, air will be taken from the room where the equipment is located. Exhaust gases will enter the chimney under the influence of natural draft.
Such Viessmann Vitopend 100 boiler equipment requires intensive ventilation of the room, which is not always possible and beneficial. The closed chamber is complemented by a smoke exhaust system. It has a built-in exhaust fan, which is responsible for removing combustion products and draws in air, which is so necessary for the operation of the boiler.
The principle of operation is built around a coaxial chimney. Viessmann Vitopend 100, which has a closed combustion chamber, has one important advantage, expressed in the fact that the device does not burn room oxygen. Additional air from outside is used for fuel combustion. For such boilers, there are coaxial chimneys, under which you will have to make a hole in the wall. This, in turn, can become a stumbling block when choosing such equipment, especially for consumers in the northern regions.
Device
The design of wall-mounted boilers Viessmann Vitopend 100-W is in no way inferior to the most advanced modern developments of the most advanced manufacturers.
The main components of the boiler:
- Atmospheric gas burner.
- Heat exchanger.
- Membrane expansion tank.
- Fan for the output of combustion products.
- Hydraulic group consisting of a three-way valve, a secondary heat exchanger, a circulation pump and connecting pipelines.
- Electronic control board, sensor system, external panel with display.
The coolant enters the boiler from the heating circuit. Passing through the heat exchanger, it heats up, after which it immediately enters the secondary plate heat exchanger, where it gives off part of the thermal energy to heat domestic hot water.
Then, in a three-way valve, it acquires the temperature set by the program, for which the hot and cooled return flows are mixed. After that, the liquid again enters the heating circuit.
The operation of all elements is constantly monitored by a system of sensors connected to the control board.
Specifications
Among the gas double-circuit boilers of this manufacturer, two main types can be distinguished - these are chimney boilers and turbocharged ones. A feature of chimney systems is that they can only be installed in rooms with appropriate ventilation and chimney.The second model is characterized by the possibility of installation in almost any room and even in an apartment, since such devices do not require special ventilation, and combustion products are removed thanks to the fan.
The standard model is a chimney, and it is purchased much more often. This version of the heating system has the boiler itself, the mounting frame and the appropriate pipes for mounting the ventilation system.
In general, the Viessmann chimney boiler has the following technical characteristics:
- The power parameters of the heater can be set independently, depending on individual preferences. On average, the minimum indicator of boilers of this type is 10 kW, and the maximum is 23 kW.
- The boiler has an expansion tank with a volume of 6 liters.
- Temperature indicators are also set independently. Usually the maximum value of water heating is 85 degrees, and the minimum is about 30 degrees.
- The dimensions of the boiler are 40×72.5×34 cm and the weight is about 35 kg.
The boiler has a control panel with an electronic indicator of the set values. This will not be particularly difficult, since all the controls are labeled and understandable. A convenient display is able to show the temperature of the water in the system, the level of gas combustion, and in the event of a malfunction, it issues a special code, the designation of which can be found in the attached operating rules. Also on the panel there is a manometer (a round scale with an arrow).
It is designed to indicate the pressure level in the heating circuit. After installing the entire system and starting to fill it with water, you must carefully monitor the readings of the pressure gauge. The manufacturer Viessmann indicates that the pressure should not exceed 1.5 bar. Also on the panel is a button to turn on and off the heater.
Separately, room thermostats are sold, on which the required temperature value is simply set, and the thermostat itself controls the heater. On some thermostats, temperature values \u200b\u200bare set, which should change during the day. For example, during the day the boiler can heat weaker, and at night stronger. There are also devices that allow you to control the boiler remotely.
