Vitodens 200-W Boiler: User Opinions, Quality, LCD Control Panels, and Lambda Control System

Hello
I am currently thinking about this boiler (220m2 approx. 19kW max demand) - everywhere a floor heating water heater + ...
I am impressed by the quality of Viesmann, which, however, overshadows negative assessments (frequent glitches + cosmically expensive repairs) on the well-known "price-based" poratals.

As for the advantages (usable side):

1. Vitodens 200-W have very interesting LCD control panels (Vitotronic 200) with external / internal / power supply indications (hardly anyone has only Cerapur)

2. Control from smartphone / internet.

3. They have Lambda Control system, which regulates the fan composition of the mixture in a continuous manner - in most boilers a rigid map of the fan speed is used, at which we are not sure about the optimal combustion ...

4. Very large modulation 1:20 - so what we are interested in the most, that is, low minimum power (eg Vitodens 200-W B2HA004: 3.2 - 19 kW, but the newer B2HB is better 1.9 -19kW).
. Is anyone able to share opinions in the use of this boiler with the B2HB symbol (apparently it is quite "fresh" ie from the second half of 2016)?

5. An additional advantage is the fact that Viesmann has very clear descriptions on his boilers on websites.

The second boiler I'm thinking about is Vaillant ecoTEC VC plus 206 / 5-5: 4.2 -21,7 kW 50C / 30C. "Troszke" is cheaper - but it does not have gas station automation - and probably less negative opinions ...

PS
For any advice thanks!

I am refreshing:
Vaillant, however, has on sale the latest EcoTEC excellent boiler, which adjusts the composition of the gas mixture in a continuous manner (as it is in the Viessman Vitodens 200-W). An alternative to Veissman is its competitor - a little known in Poland company - Weishaupt (eg Thermo Condens WTC-GW-B model), which uses a system of continuous regulation of the mixture composition called SCOT.

Start with choosing your company only from the selection of the device for the needs of the heating installation.
Assuming that the house is insulated in current standards, you need:

220 m? x 50 W / m? = 11 kW at minus 20 ° C

So you need a 12 kW boiler that allows you to descend with minimum power in transient periods (-5 to + 10 ° C outside). The essence of the selection is to choose a boiler with the minimum minimum power, which translates into gas consumption and boiler operation without timing when it is relatively warm outside and yet home heating is required.

Boilers with a storage tank from various manufacturers around 12 kW have a minimum capacity of 1.5 to 1.8 kW.
greetings

hmmm I know the patterns thank you for the calculation, but the house is from 80-90 and I do not know if 50W / m2 is not too optimistic, because quite a lot of heat escapes by gravitational ventilation, besides I have the impression that after insulation to 12 cm (previously it was 5cm) on the old Vaillant 21kW (turbo max) did not reduce bills and what's worse did not depend on the temperature (whether -5 or 0 or -10 were similar to the daily consumption of gas 11-13m3).
Therefore, it accepts 80-90W / m2 at the highest cold. I bet on a modern boiler somehow from 1.9 to 20kW ... but thank you for your answer.

Hello after 2 years
i have the same dilemma viessmann or vailant?
- that is the question


I suspect that the cauldron is already hanging and hula,
what brand do I perform?

Hello. I have since August VIESSMANN vitodens 200-in 19kw. I have a house of 120 m2. At the moment I'm happy. I came from the so-called Circadian furnace. PLN 90 for September. October 190 PLN. I remind you that the weather is in the range of 0.5 - 12 degrees C. So the stove heats the apartment every day. I have a weather system. There are radiators in the house, not a floor heating system. House from the 80s. Insulated. If you have questions, I am available ... ?

Hello, I would like to ask how there vitodens 200w works or does not break, how gas consumption ??? I am faced with the choice of a boiler, the installer offers me a much cheaper buderus gb 72. The price is a big advantage, but I care more about reliability and low gas consumption - the question whether buderus can do it at a lower price.
My house is 105 m2 of usable 135 m2 of the total will be a floor plus a water tank 100-120 liters.

Do not be guided by gas consumption, because all boilers on the market (condensing) will burn almost the same gas (plus or minus 1-2%). The first thing to look at is the lowest minimum power.

Also be guided by:
a) service in the area, type of heat exchanger (silicon-aluminum more resistant than with stainless steel but at the same time difficult to clean = more expensive service
b) the purchase price of the boiler and lumber for it
c) the price of spare parts (many brands have official price lists) (see mainly the most expensive parts such as exchanger and plate)
d) if you need it, additional functionalities
e) finally reliability. The deterioration of a particular model is often an individual matter of a particular art rather than a faulty series. And so after 10-15 years you will exchange for a newer one.

Good evening and I'm sorry to interfere. A lot of people have an oversized BOILER, because such an installer advised and then there is a problem, because the money spent and the boiler is treated and it is very difficult to set it up, etc. - please read about it. I also struggled with such a problem but I am not happy. I have Immergas Victrix Exa 24 ERP. Currently, I am much smarter and previously I had no idea about many things and today I would choose 11-12 kW BOILER and I have 100% floor and the house is unusual, because with a mezzanine and 7 meters to the ceiling: 717 m3 of volume to be heated. Greetings, Andes.

A little dig.

You bought a boiler with a minimum 5.7kW. This is not a small minimum power but it is also not big compared to 10-12kW atmospheres, which many still have in homes or apartments. And somehow they live.

By buying a dual-function boiler for an apartment or a small house, you are stuck with a minimum 3-4kW. On average, it is 4-5kW. In the fall and spring it will still be like that

With a single function, there is a larger checkbox because you can buy a 14kW boiler which also has a very low minimum power, around 2kW. But while in the house you usually have space for a container, in the apartment you are usually condemned to a dual-function boiler. and here is the whole problem, for an apartment where a boiler with the minimum minimum power (less than for an average house 100-150m2, could be useful, it is usually necessary to install a dual function).

I am thinking about buying this stove, whether the gas bills are large or it breaks often and what is the cost of spare parts, please answer

I have had this Vitodens 200W boiler for 12 years. Regularly serviced by Viessman Service. And to be honest, I haven't seen such a shame for such money. The boiler works on low parameters because the whole house has a floor heating, there are 3 people, in the summer the water is heated by solar panels.
Each inspection after 3 years did not take place, that there was no need to replace something, almost always an ionization electrode and a heat-resistant plate in the combustion chamber every 3 years. So, until year 10, each annual inspection is on average PLN 500. In 10, the motherboard died, I decided to replace it with a new one - over PLN 2,000. In the 12th year (October 2020), it began to lose pressure and after observation and consultation with Viessman, it turned out that the exchanger in the combustion chamber had broken. I paid 3400 PLN yesterday. So, to sum up, Viessman is total crap for cosmic money. Today, this boiler costs over PLN 11,000 and is so electronic that without Internet access and having an access code, it is not even possible to diagnose it. BE WARNING BEFORE PURCHASING VIESSMAN BOILERS.

I have had this boiler for 4 years.
The boiler heats the newly built house with underfloor heating.
The boiler is serviced annually (cost ? 280 each year).
After the warranty period (i.e. during the last two years), I had two failures of a boiler part for a total amount of over PLN 2,000.
First, the insulation inside the burner was damaged.
The following year, the blower module and the electrode were damaged. Interestingly, the blower module consists of 4 elements that are screwed to this module with screws (after replacement, I disassembled the damaged module). The service cannot replace the damaged element, only the entire module which costs PLN 1,400.
In addition, the furnace has the ability to analyze the history of gas and electricity consumption. A very nice feature that I use. However, twice in these 4 years of use, the data in question has been deleted from the boiler (the website cannot explain why and claims that this data cannot be recovered)
To sum up, I do not recommend buying this boiler and looking at the service policy and prices, I do not recommend Viessmann products in general.

Now Viessmann provides a 5-year warranty on the Vitodens 200-W, so all the repairs you write about would probably take place under the warranty.

You're right. But it does not change the fact that the price should be of a different quality of the device. And it shouldn't be so emergency.

I have a Vitodens 200-W B2HA boiler. Apart from the faults related to the broken electrode seal and the electrode itself, there is one more problem that keeps me awake at night - the exchanger is corroding.
We have had this boiler for probably 8 years. The exchanger has already been replaced 3 times. Previously, air was sucked in from outside the building. After chemical analysis, it was shown that corrosion is caused by wood dust emitted by a nearby plant.
Currently, air is sucked in from inside the building, we have filters installed in the boiler room, and the exchanger is leaky again after two seasons of heating. Inside the boiler, slag in the form of flakes is visible. Everything is in a sorry state.

Have any of you also encountered this problem?

Previously, there was an old boiler that never had such problems.
My neighbor has a different model and nothing is wrong with him.

Or maybe your service technician cleans the exchanger with a wire brush during the inspection so that the exchanger looks like new?
