Which gas stove - Viessmann, De Dietrich or maybe ... Termet?

You probably forgot what was in the topic and you are debating among yourself, look at the author's first post

but not with a 2-function boiler, because when I associate it, you have electrics at home, so different conditions.

Do not manipulate the facts, because with a flow water heater like a boiler, a 2-function thermostatic mixer does not help to make its purchase sensible.
Such a battery makes sense when we have a hot water heater that offers a stable domestic hot water temperature

It's strange that you know better than I do. I have had a Buderus atmosphere for 11 years. And this is what I heat DHW. Only this. (even there is a thread in which I describe the problems of my boiler)
How do you know that the battery is not helping. I have it .... and how it works for me. But you know better even though you don't have one And who is manipulating here.

Originally, there was a mention of a delay of a few seconds when switching on the domestic hot water in a new gas boiler, which has its consequences, which I wrote about. You turned it into supposedly several seconds of waiting for hot tap water, which is manipulative and untrue.

and a friend described it like this ...

Disadvantage - no water tank and high water costs after unscrewing the tap, the water flies, starts from 3 // 5 seconds before it heats up, half a bucket of cold water runs out.

So who is manipulating here?

Installing the tray reduces these fluctuations, increasing comfort, so your 4 or 3 seconds with the tray instead of 5 seconds without the tray are data completely unrelated to the topic.

Give a quote in which a friend writes about temperature fluctuations ...

You have trouble understanding what the author meant.

I do not know if you will understand it, but I will try to translate it into a simpler language.
According to sp5-4013 the disadvantage is the lack of a hot utility water tank, which generates water costs, because after turning on the tap, the cold water flies and the boiler starts only after 3-5 seconds, and then before the water heats up on the boiler and reaches the tap, according to his assessment, half a bucket escapes to him sewerage.
Among other things, I described this process in my elaboration, mentioning 30-60 seconds of waiting, which you, in your own way, laughed at and ignored.
You brought it down to the fact that a friend is impatient and does not want to wait 3-5 seconds before he has hot water in the tap, which is just nonsense and a story made up by you. In the further part you are trying to insinuate that if without a tray, the waiting time for hot water in the tap is 3-5 seconds, how much can you gain with the tray, in your opinion, if it goes from 5 seconds to 4 or up to 3, it is an investment of several hundred / several thousand zlotys in the tray is completely pointless.
This only shows that you have no idea what you are talking about, even though you allegedly have practical experience.
According to me, if you have experience and know what you are writing about sp5-4013 you would not write such nonsense that is off-topic, because you mix 2 completely different things like some layman, not an apprentice.

I usually have no problem with reading, but when you give counter-arguments by quoting others, do it honestly and give the entire important fragment:

For me, this implicit stoppage for a moment and then unscrewing and initiating the cycle again means temperature fluctuations and a decrease in comfort, hence his final statement that the next time the boiler is replaced, it will be with the reservoir.

What is obvious to me, it is not so for you, so I am finishing my polemic with you, because it is just a dead end that brings nothing.
If you don't understand what he is writing about sp5-4013 it's your problem, not mine, because I have enough practice to figure it out and understand it.

I can admit that I was wrong, but so far you have not given any argument that would suggest that you are right and I was wrong. So far, all signs indicate that it is the opposite, which is why I am shocked by the lack of reflection on your part.

Hello !
Returning to the topic ... on Sunday afternoon (frost went up) the alarm in the house, the stove does not heat up !! ??
Bake dead actually.
Errors 7, after turning on momentary start error 8. Reactivation error 46 and the chapel.
A void in the head, foreman, about 50 km, will I come on Tuesday?
I learned the instructions by heart with my brother who is going to buy (a stove) that we meditated - we are checking the condensate drain - suggested by error 46 - my service technician also mentioned it.
Hit - it came out of half a kilo of "rubble", tarry plastic fractions?
I cleaned / rinsed better than the drain filter to the sewage system
I put it together, I started the stove around 4 o'clock (in the morning).
He started off the hoof, everything went like clockwork.
The foreman arrived on Tuesday morning and looked (I ... gave). The stove cleaned the combustion chamber and we forgot to clean the filter and drain.
The sticking of the stove disappeared, it is difficult to describe it in words ... the masters probably know what he is writing about.
By maneuvering the heating curve - 1.5 heating from 35C / p-55C / Z, in frosts the stove worked perfectly at a temperature above 55 / power supply - set on the detector - heating suspended - the circulation pump cooled down to about 45C -10 / 15 minutes and the heating was turned on again. (to professionals, is it correct ??) - in case of intense frost! outside the window below 10C at night to -20C.
Currently, frosts have fallen, the curve is set to 2.0 and the flow temperature is 50C / 30C return.
The comfort of keeping the temperature in the house at 23C.-stove (knock on) like a NEW one has DEFINITELY improved.
My brother buys - a termet because with the Viessman 100 that the master offered him will not go down with power (minimum 7kW), Termet 2/3 kW (gas saving), these functions are supposedly Viessman200 (a solution like the above-mentioned Termet) but the price is twice as high.

Book combustion measurements in accordance with WT - probably lack / difficult drainage of condensate - steam with gas ??? in case of intense frosts and higher combustion, the error (46) showed the above-mentioned problem with the stove.
Greetings to colleagues who write comments on any troubles, I will not hesitate to speak up.
Ps.Kol BUCKS is right !!!! - I have been exercising for 6 years and I know what I am writing ... for unnecessarily used water, I would buy a new stove with a tray ..... , etc., the cold water flew down until the heat appeared.
wnot-buddy, please look at automatics / electronics (brother of automatics)
this is how the electronics in Termeta are constructed, then the automation - my fault is that about 4m must flow into the bathtub, non-insulated pipes (I will not choke the bathroom / tiles), I did not think about the tank and the pump when lighting, and the light sensor and starting the pump so that I have warm water in the tap -but it's a different story.
Sorry to the MODERATOR for thatWe moved away from the topic and thread, but I think that my adventures will also be a clue to choose a stove - I asked what kind of stove on behalf of my brother and I took the "wolf" out of the forest.

If we are talking about condensing boilers, they all meet similar requirements and in this respect are of a similar class, so for example what low emission you write about.
For example, according to the instructions, Termet Silver 20kW has the emission of nitrogen oxides at the level of 21mg / kWh and the MCR Home 20 / 24MI boiler 38mg / kWh .
The maximum exhaust mass flow rate is 0.014 kg / s for Silver and 0.012 kg / s for MCR Home.
I don't know what you mean by efficient.
Termet at 80/60 has a power of 2.7-20kW for central heating and 2.7-25kW for domestic hot water
Die Detrich at 80/60 has 4.8-20.0 kW for CH and 4.8-24.0 for DHW
As for the sound power, both boilers have po 48dB .

Functionality and ease of use may be a relative concept, and the prices of both boilers are similar, but the Termet is a bit cheaper.
In other words, you give a boiler model that allegedly met your requirements as the only one, but you cannot see its significant advantage and nothing special stands out from the crowd.
