Wall-mounted series of gas boilers Viessmann Vitopend 100-W: main faults, owner reviews and instructions for setting up the device

European manufacturers of heating equipment are known throughout the world and are considered the undisputed leaders in this field.

High quality, advanced design solutions, and our own high-tech production make the products of European companies a standard for all other manufacturers.

] Viessmann[/anchor] was founded about 100 years ago and has managed to develop a lot of its own methods and production secrets.

Gas boilers occupy a special place in the company’s product range, since this method of heating homes is recognized as the most effective and economical.

Let's consider one of the series of wall-mounted boilers from this company.

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 rooms. The optimal use case is apartments, residential buildings, office, commercial or public premises with an area of ​​up to 340 m2.

The peculiarity of this series is its 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 outside air temperature. It is possible to independently heat hot domestic water, or connect an external boiler, if necessary.

The boiler electronics have a built-in timer, with which you can program the operation of the installation for a week in advance. Low noise levels and the absence of foreign odors make the use of boilers in residential premises safe and comfortable .

Why does it go out?

There can be quite a few reasons for the self-extinguishing of gas boilers, from external factors to self-blocking of operation by a signal from the boiler automation.

Let's consider the most likely:

The reasons for self-extinguishing of the boiler can be interruptions in the power supply and poor supply ventilation . To determine the source of the problem, the most common factors should be consistently eliminated in order to identify the culprit of the boiler shutdown using a method of elimination.

Design options

There are different designs of Viessmann Vitopend 100-W boilers:

• Single-circuit. They are designated by the letters A1HB (for example A1HB001). They only heat the coolant for the heating circuit.
• Dual-circuit. These settings are designated A1JB (eg A1JB010, A1JB009). In parallel with heating the coolant, hot water is prepared for domestic needs.

All single-circuit boilers have the ability to connect an external boiler, which allows not only to heat the coolant, but also to supply hot water . At the same time, the volumes of hot water are much greater than what a standard plate heat exchanger of a double-circuit boiler can provide.

This is convenient if the room size is relatively small and the need for hot water is large.

Why is blood pressure rising?

An increase in pressure in the boiler is a very dangerous sign . It indicates an increase in the volume of liquid and a lack of compensation from the expansion tank. A possible cause could be an open water supply valve.

If it is closed and working properly, then you should look for the problem in the expansion tank.

Water, like any other liquid, is practically incompressible . When heated, it expands, causing the pressure to increase significantly.

As pressure increases, it bends, allowing excess water to fit. However, if the tightness of the membrane is broken, the water will completely fill the volume of the tank and the excess liquid will have nowhere to go. This will cause a constant increase in pressure .

A sign of this may be the constant operation of the relief valve. The solution to the problem is to replace the expansion tank.

Series models

The Viessmann Vitopend 100-W series has two model lines:

• Single-circuit boilers are designated by numbers from 001 to 004.
• Double-circuit boilers are designated by numbers 009-012.

Numbers 001, 002, etc. indicate the boiler power.

Each model is marked with its own digital code:

• Number 001 is assigned to a single-circuit boiler with a capacity of 24 kW.
• 002 - single-circuit boiler, power 29.9 kW.
• 003 - power 34 kW.

Double-circuit boilers start with number 009:

• 009 - 12 kW.
• 010 - 24 kW.
• 011 - 29.9 kW.
• 012 - 34 kW.

Codes 004 to 008 are assigned to ready-made solutions, sets of single- or double-circuit boilers and external water heaters.

Digital marking is convenient in that it allows you to shorten long symbols to three digits, which accurately indicate a specific boiler model. This is convenient for both technical personnel and retail chain workers, speeds up model identification and simplifies document flow .

Specifications

Let's look at the general characteristics of the Viessmann Vitopend 100-W series boilers:

Pressure drops

A drop in pressure indicates a leak. This could be a dump valve stuck open, a leak in the expansion tank or heat exchanger, or damage to the pipelines or radiators of the heating system.

Usually, all problems in the boiler itself are immediately noticeable by drops or puddles of water.

Finding a leak in the system is more difficult, especially if underfloor heating is used. The solution to the issue can only be to detect and eliminate the leak or replace the unit unit that has lost its seal.

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.

Main boiler components:

• Atmospheric type gas burner.
• Heat exchanger.
• Diaphragm expansion tank.
• Fan for removing 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. As it passes through the heat exchanger, it heats up, after which it immediately goes to the secondary plate heat exchanger, where it transfers part of the thermal energy to heat hot domestic water.

Then, in a three-way valve, it acquires the temperature specified by the program, for which the hot and cooled return flows are mixed . After this, 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.

IMPORTANT!

Any error, malfunction, failure of a structural element is immediately recorded by the corresponding sensor, the signal from it is sent to the control board and displayed as a code on the display.

Peculiarities

The Viessmann Vitopend 100-W A1JB010 model has the following overall dimensions - 400x725x340 mm (WxHxD), while the weight is 32 kg. Installation is carried out on the wall, which saves space in the room.

Principle and main operating parameters.

The convection type of device involves the generation of heat from gas combustion, while the boiler operates on natural gas (methane, consumption 2.77 cubic meters per hour) and liquefied gas (propane-butane mixture, consumption 2.09 kg/hour).

To obtain the declared power of 24 kW, the pressure of natural gas must be at the level of 13-20 mbar, and the permissible pressure of liquefied gas - 37 mbar; when these parameters decrease, the thermal power will also drop. ExpertKotel.ru reminds that most often in domestic networks the pressure is 12-20 mbar. The efficiency of the heater, with such indicators, is at an excellent level and equals 91%.

Heating of water, coolant in pipes

. This boiler is capable of producing 11.2 l/min of hot water (t=30°C). The coolant temperature is 40-80°C, and in the hot water supply circuit - 35-57°C.

Circulation pump

necessary for the circulation of coolant (water, antifreeze) through the heating circuit, it is a mandatory component of a closed heating system; in our case, the pump is included in the kit.

Expansion tank

compensates for the expansion of the coolant in the pipes during heating and releases it back into the system during cooling. This maintains constant pressure in the circuit.

Fuel economy

Burner flame modulation

makes it possible to smoothly regulate the intensity of the fuel supply and reduce/increase the flame, which allows you to reduce gas consumption.

Auto-ignition (or Electric ignition)

allows the Viessmann Vitopend 100-W A1JB010 to start and extinguish the burner according to an algorithm when necessary, which saves fuel.

Gas consumptionValueNaturalLiquefied

Management and control

The Viessmann Vitopend 100-W A1JB010 gas boiler is electronically controlled, equipped with a display and has a port for connecting additional devices (most often thermostats, programmers, room remote controls, etc.). The advantage of the electronic system is that it does not require the constant presence of a person and allows significant fuel savings (as described above), the disadvantage is that it is more complex than a mechanical one and depends on voltage drops (it can fail during surges).

Thermometer and pressure gauge

. A thermometer is necessary to monitor the temperature of the coolant in the boiler, and a pressure gauge shows the pressure of the coolant; this is an important parameter, because exceeding it can lead to breakdown of individual parts or the system as a whole.

Protection systems

Gas control

- a useful and necessary function of the burner; if the flame goes out for any reason, it stops the gas supply automatically.

Safety valve

"Viessmann Vitopend 100-W A1JB010" protects the system from excess water pressure in the circuit in excess of the maximum permissible norm.

Air vent

. An important element of the safety group, when the pressure in the heating system increases, the air vent automatically releases excess air, most often working together with a safety valve.

Coolant freeze protection

independently turns on the burner for a short time, provided that the water temperature drops to a critical level and there is a risk of heating defrosting. It is worth remembering that for this there must be gas and electricity.

Pump blocking protection

activated when the boiler installation is idle for a long time, in this case the pump turns on for a while and turns off itself. This is necessary in summer when the heating circuit is not activated.

Coolant overheat protection

turns off the burner if an abnormal water temperature value is detected.

Connection

• The connecting size for the gas pipe is 3/4″.
• Hot water supply - 1/2″.
• To connect the heating circuit - 3/4″.
• The diameter of the coaxial chimney is 60/100 mm.

To connect the power supply, a 220 volt network with a pure sine wave and grounding is required.

Operating instructions and malfunctions

The Viessmann Vitopend 100-W series boilers operate automatically. The owner can, if necessary, adjust the temperature, turn off the heating circuit or the entire boiler.

No special measures are required from it, except for periodic cleaning of the case from dust and dirt.

Any breakdown, error on the display or shutdown of the boiler is a reason to immediately call a technician from a service organization.

Please note that the appearance of an error on the panel can be caused by various reasons, so it is usually first reset by pressing the “R” button. If after several attempts the error does not disappear, you need to contact a specialist .

Any attempt to repair the boiler yourself is considered to be the end of the warranty period. You need to remember this and not take unnecessary risks.

Error f4 on Viessmann boiler

How to set up the device correctly

The initial setting of the boiler is carried out at the manufacturer, about which the user is notified in the instructions attached to the boiler upon sale. Installation and ongoing settings are carried out by technicians from the service center, so the user can only change the operating mode in accordance with the microclimate of the room and his own feelings.

All control is concentrated on the external panel . By pressing the “mode” button, you select a mode, and use the up and down arrow buttons to set the appropriate temperature.

There you can also enable summer and winter operating modes (DHW only or DHW together with heating).

NOTE!

All actions are simple and intuitive; if necessary, you can consult the instructions, which explain everything in detail and with illustrations.

Doesn't start

Turning on the boiler is often immediately blocked by automation that detects problems in the system.

Boiler failure at startup can occur for several reasons:

You can figure out the gas or electricity supply yourself. People often forget to open the gas tap, or when connecting the boiler to the network, they use a regular socket, which makes it possible for the phase to be connected incorrectly.

Bleeding air from the system also does not cause any problems . All other problems can be solved only by contacting the service center.

You should not try to solve the issue on your own, since most often a lot of others are added to one problem, which requires expenses and does not guarantee a favorable result.

Price range

Prices for different models of Viessmann Vitopend 100-W boilers range from 40-57 thousand rubles. This cost does not include additional devices, such as a chimney (7-9 thousand rubles), voltage stabilizer, water filter, etc.

In addition, you will need to pay for delivery, installation, and a fee for drawing up a warranty agreement..

In remote areas prices will be increased due to shipping costs.

IMPORTANT!

You should not try to save on warranty service, since any breakdown may be too complex, and repairs will become an unwanted financial burden for the owner.
