Immergas Victrix Exa vs Tera Plus: Comparing Monofunctional Boiler Differences & Features

Hello, what are the differences between the two boilers? Both are to be monofunctional.

Hello. Please give more details on the type of furnaces for comparison.
https://www.immergas.pl/Produkty,7296/KOTLY_KONDENSACYJNE?dest=1&category=7296

Specifically, I mean VICTRIX TERA 24 PLUS and VICTRIX EXA 24 X 1 ERP. Warm water from a 140l tank

Hello. The newer model, smaller dimensions. other automation when it comes to the service mode (cheaper boiler). EXA-older model, dimensions a bit larger, (service mode is not a philosophy for a service technician) now it's his successor, a proven model with very little failure, (not much more expensive than the new one, at least from my sources I know it) but I would choose EXA personally. maybe because I trust this model and installed more of them.

Thank you for the information, but I will choose this EXA.

The installer recommends a newer version, Tera Plus. So I have two conflicting opinions. Maybe someone wants to comment. best regards

How's the situation? I am faced with the same choice.

Rysiek took a risk and followed the service technician's hint. Because I believe that the prices of boilers are completely abstract, the termet - the cheapest condensate was supposed to be (the previous one is 20 years old and working goes down in history). I paid PLN 3,580. I installed the boiler and put it into operation in December before Christmas. At the beginning of January, a service technician came and officially launched it. It went without problems. The boiler works with coal. It's hard to say how much gas he would have consumed himself. In tandem, it consumes 3 to 5 m3 of gas when working at night (in the morning) and a little during the day. He does not cause any problems, he is not tactful. It is set to the minimum parameters and works on them. When turned on for a short time, it sometimes increases the power. Not treating. It is controlled by the salus programmer. I used carv2 for two weeks. Everything is fine, but he clocked more often. Apparently it works better with more floor heating. Perhaps he needed a different setting. It probably was beyond my service technician. My experience allows us to recommend this boiler. It does the job perfectly. There is no point in spending a single zloty more. Unless someone has a very complicated system, Perhaps then a boiler with other options is needed. I also wonder if I did the right thing by resigning from the termet. 600 PLN would be in your pocket and the heat would be the same. I found a lot of positive opinions about these boilers. best regards

Let me know how Tera 24 is doing? I also have this dilemma whether now 24 or the proven exa 24, but now has a lower minimum power, maybe not much but always 1.4kw is always something?

Nobody will help with the topic ??? Let me know which model are you betting on? Is immergas tera24 or exa24 and why? Pleats, help?

Hello. As I wrote before, I focus on the exa model, but over time the tera model turned out to be equally successful in my opinion due to its smaller dimensions. The lower price and its trouble-free operation, I can confidently recommend this boiler model. It's a successful immergas product so it's worth hitting it.
Best regards.

And is there an argument for exa because checked or for now because some other argument for one or the other? How, for example, better parameters now when it comes to power consumption or lower modulations from 4.4kw and exa 5.7kw, do not consider this as an argument for now? Possibly some other sigest after one or the other because the size and this small difference in price or another program for the diagnostician does not indicate the winners here, but I thought about the parameters that they are better on the part of now?

Added after 10 [minutes]:

Of course, thank you for your answer and I would be grateful if someone would tell me if this is an argument on the page now that the modulation is from 4.4 and some other specific differences that possibly will allow me to choose between them because the size or price or decibels do not matter to me but I was looking for the usefulness of the lower modulation parameter, plus that now they provide a lower power consumption, which is not a big difference, but also of course the tubular type of the exchanger which praises the service technicians and I paid attention to these features? I am asking for a more precise comment, and thank you for each hint because it is very helpful because there is not much about this new tera boiler and the differences between exa and tera.

hello, my observations after a month-long battle with sellers and installers are such that we can break our questions. It's like buying a car or other things, everyone has the wheel. Always answer that it is enough, but there will be no specific information.
Please imagine that no one, be it the seller or the installer, mentioned or knew about the famous recipe about the ejection of the chimney through the wall, where you can only do this up to 21 sq. Everyone says that the side chimney can be done with these parameters and this is not a problem, but they do not answer why such powers are in the regulations. I still do not know, and the sellers, the service technicians are persuading to break the law! it's a bit cheaper as a termeta to keep a long warranty. I'm only worried about the high modulation exa compared to the present. All sellers recommend exa, I don't know why, because no serious arguments were given. So I know that I do not know anything further on this topic. My argument is long and does not contribute to your question, but I wanted to write that others also have a dilemma. I will write one more. All this is propaganda about the quality of the company, one way or another. Take what costs on average and the warranty will not cost a second stove because everyone earns on it. This week I have a meeting with the installer, maybe I will learn something new.

I have already found out what the difference is exa vs now, only the exa model is older and proven and now a young model but I already know that it is also successful because the service guy with 50 started and after 2 years no problems and recommends, an additional plus lower parameter modulation, also boldly take!

I am also faced with this choice:
VICTRIX TERA
VICTRIX EXA ERP
VICTRIX TT ERP

Only underfloor heating and a 160 liter water tank ...

Which one to buy?

TT collapses quickly and Exa is an older Tera model, in turn Tera lower modulation, which can be useful when flooring, they recommend exa due to the fact that it is a proven and failure-free model, but I know from conversations with service technicians from regions that it is also successful, it has new exchanger and slightly improved performance, I think that if the service is available in the area, you can take it now. this is my humble opinion, the more that I'm already hula.

So should I reject TT at the start?
It will always make the choice easier

I have such knowledge that the TT model, in fact, in wholesalers, service technicians advise against selling them because there are still some breakdowns, this is knowledge from a reliable source.

After about 6 years, the Victrix TT boiler becomes more and more a trusted boiler. Unfortunately, the fouling of the burners comes from the fact that the installers are still trying to save money and install long chimneys 60/100 instead of 80/125. At first there was a bit of confusion with the setting and adjustment of these boilers, but now they are one of the cheapest boilers in the service. Plus, as mentioned before, TT can be thrown through the wall because there are two powers that allow it, i.e. TT 12kW ( 1.9 -12kw modulation super under floor heating + 160l storage tank) and TT 20kW

As for the basic differences between the TERA and EXA boilers:
Another design of the exhaust gas water exchanger
TERA - one-pipe coil - aluminum housing
EXA - sectional heat exchanger - 4 coils connected in parallel - plastic casing

Different quantity in control and safety elements
In the TERA boiler, an additional sensor on the return from the central heating system
Additional combustion air pressure switch in the EXA boiler - no return sensor
Different minimum power of the boiler
TERA 4.2kW
EXA 5.5kW
Other parameters in the boiler service menu.

VICTRIX TERA boilers have only one control input, which, after being turned on, the device detects in the auto-detection process whether an ON-OFF controller is connected to the control input (the control signal is a potential-free contact short-circuit) or a dedicated controller with digital communication IMG BUS.

From the information I inquired.
Like Immergas Terra and Exa, they are very successful economical stoves. I have Terra plus 28 myself and I will buy the other one.
With more kw, choose only EXA PRO.
In general, I do not know if there is a more successful stove on the market. Additionally, their service is available and cheaper than others.

Hello cordially,
Please allow me to refresh the topic. I, too, am facing the problem of buying a Vitrix Exa 24 KW or Vitrix Tera 24 Plus single-function boiler. I have to heat about 160m2 of a one-storey house, insulated with 20cm of Styrofoam and 30cm of wool in the roof.
Both boilers are very similar but it puzzles me why the older Exa boiler is on average 500 PLN more expensive than the newer Tera.
Analyzing the technical data, I noticed two significant differences:

1. Displacement pressure at 1000 l/h:
Tera - 9.19 Kpa/0.9 m.c.a
Exa - 29.6 KPa/3.0 mH20
That is, what Exa will raise the water column to a height of 3.0 m and Tera only 0.9 m ???? (weaker circulating pump)

2. Annual fuel consumption for central heating function. (Qhe):
Tera - 12250 kWh/44.1GJ
Exa - 20639 kWh/74.3 GJ
This means that theoretically the Tera will consume almost 60% of the fuel (gas) me,j than the Exa under the same conditions.

Greetings and waiting for an answer. In 2 - 3 days I have to decide what to buy.

And by the way, what are your opinions after these several years of use of these boilers.

Greetings.

Yes, for anyone interested.

After talking to an Immergas employee, I decided to choose Exa. He confirmed that Tera can produce lower pressure thanks to a different exchanger (supposedly creating greater resistance) and a different built-in circulation pump. He was unable to guarantee that Tera would not have difficulty heating in the radiators on the first floor of the building.

As for gas consumption between Tera and Exa, he probably ruled out that they differ significantly, and certainly not to such a large extent (by about 60%), although he could not indicate where such data is found in the product cards and on what basis have been calculated.

So I preferred not to take any risks with Tera and ordered Exa.
