Differences in Termet Ecocondens Silver, Gold Plus and Crystal condensing boiler

I plan to buy a boiler, I collected the difference in individual models:

GOLD

+ slightly lower nominal gas consumption because the power for domestic hot water 19 kW (Silver 24 kW) as found for low hot water demand
+ about 4 cm lower than silver
+ cooperation with the regulator EASY REMOTE and OpenTherm CR11011
+ Connection of a regulator with a 0-10V signal
+ control board of the Polish company Tester (constantly updated and treated as development with the possibility of updating to gain access to adjusting new parameters!)
+ b.works well with trays
+ several different service parameters in the control system related to the possibility of adjusting the boiler to a given installation (setting the minimum and maximum pump revolutions, the rate of burner power increase in the initial heating phase, which affects the
economics and stability of the installation, the ability to set the hysteresis of temperatures in the central heating system, the parallel shift of heating curves for the weather forecast, self-setting the difference between the supply and return from the installation - the ECO function (this is not in Crystal) and several other parameters (according to Arek Komar from Termet ) the driver is not specified
+ Anti cycling time, adjustable 1-60 min
+ DHW pump overrun time (adjustment 20-180 sec)
+ in a few months it will be possible to control via the Internet and a smartphone using a new adapter, everything is already in Termet, it is only being tested :)

- the most expensive of the compared (differences are eliminated by funding available in many communes!)

SILVER

+ prepares hot water faster and more efficiently, designed in particular for instantaneous hot water heating
+ has a more durable exchanger, but I don't remember which one
+ is the cheapest

- higher nominal gas consumption because the power for domestic hot water 24 kW
- Italian Nordgas driver, no official possibility to repair and update the software with new functions

CRYSTAL

+ several different service parameters in the control system related to the possibility of adjusting the boiler to a given installation

- older model (not development)
- intended more for cascade assembly

Feel free to post your comments, especially your experiences.

Hello!

I'm considering a condensing boiler as well
Termeta, because it is a domestic manufacturer, easy access to spare parts and relatively cheap parts...

Is there no access to the above-mentioned various service parameters in Silver as in gold?

At the moment I am leaning towards Silver 2F 25KW, these are on sale in a well-known network
Ca-sto-xxxx together with the room controller, but as someone wrote, there is a regulation limiting the power of the boiler for central heating with coaxial cables exposed through the outer wall to 21KW, and this one has 25KW.

Up to 21 kW power from TERMET are:
Crystal II 20
GoldPlus 20

Okay, why not Silver?
Termet EcoCondens Silver 20 single-function condensing boiler
-code WKJ4401000000

or
Termet EcoCondens Silver 20 combi condensing boiler
- code WKD4391000000

Aren't they 20kW?

In the technical data on the manufacturer's website you have the following parameter:
"Heating power (at 50/30°C) 3.0 - 22.0 kW"
and it already exceeds 21kW
Here link

Yes, however
Heat output (at 80/60°C) = 20KW.

And does the regulation specify for what conditions it should be < 21KW?

There is nothing in the "regulation" about temperatures - you need to see exactly what is on the rating plate and there can be 22kW.

And what are the risks of installing a larger boiler with a chimney through the wall? e.g. 22kW

I don't know - maybe you should ask in some building inspection

I've been to a few wholesalers, but now the "nameplate" is a piece of foil
sticked on the inside of the boiler... It is impossible to see anything, or almost nothing, without removing the boiler casing... another flower...

In one of the shops I found a table where the heating power of 20KW for the boiler is specified:
EcoCondens Silver 20 single-function condensing boiler code WKJ4401000000

It's just that I don't know where this table comes from...

nix,
Junkers' engineers also decided to put a sticker with basic information under the cover, additionally covered with tubes - for me it's just thoughtlessness!!! Because how to provide the designation / model, e.g. to a service technician ???

Coming back to the topic, I decided on the Gold version. Both 20 kW and 25 kW start modulating from the same values. Besides, thanks to the co-financing from the commune, the silver/gold price difference will remain around PLN 200-300. I am attaching two interesting leaflets on the differences:

Side thread, we don't write about it HERE! Moderators please move to the appropriate section.
The worst thing is that it's currently hard with appointments with fitters in the western area of Warsaw. If the manufacturer had placed all the necessary information in one place, and the Termet hotline had more competent employees, I could have made the decision 1-2 months ago.

Maybe someone will recommend a fitter / service in a private message so as not to lose the transparency of the topic. I would prefer it to be ONE person who will install and set up the stove (I know there are such people ) There is an opportunity to prove yourself, because knowing life in a few years when there is a problem, I will write about it here and after a while there will be pointing out mistakes: "and who installed / connected like this "
So I invite these sages in the first place. Currently, there is a gas stove, all you need to do is modify the connections and insert the insert into the chimney.

In fact, I have not seen Termet before - but yesterday on the Castora_xxxx network - I watched Silver 2F - this one has a sticker on the side, but the outer wall - so here you can read the parameters without any problems.

Interestingly, in addition to the classic nameplate, there is also a second one with the description:

"Co power set = 24KW"
"DHW power set = 24KW"

I have given the powers as examples, it is a pity that I did not take a photo of this sticker.

What made you choose Gold?

Feel free to post your comments, especially your experiences.

you presented the advantages of Gold Plus too rosy (I have this type), which look good on paper, but the practice, at least for me, has shown that the new control via the Internet is underdeveloped and works poorly with the boiler. Currently, the board is in Termet (over 1 month) and problems with obtaining all parameters.
Despite the descriptions in the instructions that the boiler has a Tank-Timer, it is not true and a scam. This feature does not work. Weather theses.
In the latest models, they even withdrew from it, but not in Gold (advertisement more important than the customer). It is but it doesn't work.
Gold does not work with Easy Remote only Round on-off and opentherm (half), cr 11011 (not all functions), all room 0-1.

And what's with this weather forecast, why doesn't it work? Did you pursue the topic?

I know the problem perfectly, but only for Ecocondens Gold Plus produced after November 1, 2017 with control number b.11 and operation in the Opentherm option.
The control can be carried out by simple on-off programmers including Round wifi on-off or by a digital signal of the OT protocol. Also the 0-10V signal works fine.
And here is the problem because the software version b.11 works correctly using the heating curves using the above-mentioned 0-1 programmers, but in the case of the opentherm signal with Round wi-fi OP it is programmed in such a way that the OT gate blocks information about the WG temperature from the heating curves.
Practically, the gate is superior and so that there are no two regulators for one object, the control using heating curves is blocked and the gate modulates the signal using only one value of the set temperature of the WG.
Therefore, the heating curves symbol is not visible on the boiler display.
Full OT control is provided only by the universal controller CR 11011 but not by Round wi-fi OT.
This will be changed in software version B.12, which will appear in new boilers in about a month. There, Round will be able to use the temperature resulting from KG and modulate the signal for the boiler on this basis.
TankTimer in the new generation boiler will probably not be installed.
If someone has an older control, it is possible to reprogram it to the latest one in the Tester via the Termet service.

I would like to ask where did you get the information about the upcoming version of the b12 firmware? Will it be out in a month or so in December?

I had a long conversation directly with the IT specialist who is preparing the program. There will also be a period of testing by Termet

I'll stick to the topic of differences in boilers:

EcoCondens Silver vs TermGas Condens

That is, I was recommended to buy an EcoCondens Silver boiler. So I started looking for information about him, I found his symbol in the company's price list: WKD4351



Then I started looking for the best deal with these boilers and found it in a DIY store. Exactly the same symbol but named TermGas Condens.



Same symbols and different names. I tried to call Termet but to no avail. So I decided to ask the question here.
Are these EcoCondens Silver and TermGas Condens boilers the same boilers, only the name is some kind of marketing change?
Or maybe what goes to DIY stores is some depleted version (or maybe enriched )?
If anyone knows the differences, please explain.
I would also like to mention that on the Termet website I could not find anything about TermGas Condens boilers.

It's almost the same but almost makes differences .... because the one from the market has a different fan, i.e. a more plastic one to make it cheaper, and the gas valve has a different one, because the stove in the supermarket must be cheaper.

They are probably some kind of crap that, if necessary, can be replaced with better ones.
I mean more important things, such as a heat exchanger or, for example, a pump, controller, its software, etc.

For those interested, I put a common installation instruction for stoves:
Silver, Termgas and Termmax .
