    Read about Buddy about Gallmet. I have been using it for a couple of years (by order of my friend).
    Until today, it works flawlessly.

    Hello. If you care about the least amount of effort put into service of the boiler and boiler room, think about BIAWAR or LAZAR. If you like some work at the boiler and in the boiler room, I recommend other popular companies. BIAWAR and LAZAR are undisputed leaders among Polish producers, ACV, KOSTRZEWA, GREŃ, DEFRO, HEIZTECHNIK is the average shelf, the rest is below the average to a low quality shelf, and in terms of service and capabilities.

    Well, I do not really know? Teeth is like a cauldron top :-) how I looked at the functions it has everything that smart fire and standard emission sensor in the light, for example it is an option for PLN 1000 again, the best efficiency has a tooth for Zbyszko I have a 10-year warranty on the tightness of welded body water body and 60 months warranty for water body tightness ... all bets between 10000-15000 zlotys, and this Agate 20 is the best for me but I do not have any experience with pellet boilers or Ząbca ... Has anyone had the pleasure? maybe it is cool, it is described, but in reality it is not like that ??

    Added after 5 [minutes]:

    As for the galley, how did I see this efficiency at the level of eco-pea 88% others have over 90% do not know if it's not inflated values and do you want to control them all ?? somewhere on the forum I read that it's average quality boilers but since you recommend it, I'm still looking :-)

    Hello.

    Mati19842112 - my suggestions of producers that I have presented to you result from the experience gained during the years of assembly, service and service of various pellet boilers at clients. I have been dealing with pellet boilers for about 15 years, so I have some experience.
    I had an agate boiler in late spring, so I had the chance to take a good look at it. I improved the installation in the boiler room after another installer, because he installed this boiler as an ordinary trash, and it was terribly difficult to install the boiler together with the boiler. The boiler that you are interested in is a converted coal-fired pellet burner, a tank with feeder and control automatics has been added. In this boiler at its temperature of 65 degrees, the flue gas is about 160-180 degrees, while at the same manufacturers at the same boiler temperature, the flue gas is 80-100 degrees. This indicates the thermal efficiency of boilers, and thus the amount of fuel burned. Look also at the warranty, on welds for ten years, and the tightness is only five. Leading manufacturers for the entire complete boiler (boiler body, burner, pellet tank, feeder, automation) 5 years. Each manufacturer will praise its own, listen to users, people who have experience in handling pellet boilers, they will certainly guide you in the right direction, they will advise you.
    Between 10,000 and 15,000,000 you can already have a really great boiler, plus 4000-7000 for equipment (materials) boiler room + labor and then enjoy a fully automatic operation of the installation without having in the boiler room dirt and stench.

    Sstalone - Biawar, or rather Nibe created its boilers and burners from scratch only to burn the pellets, the first over 40 years ago, which is why these boilers have an advantage over the majority of other boilers processed from coal-makers or oilers. Pellux-y Biawar have mechanical cleaning of the burner tubes and the burner, thanks to which they maintain a high thermal efficiency throughout the heating season, a thermally insulated combustion chamber in which the pellets are almost completely burnt at very high temperatures, which is associated with clean fumes and a small amount of ash, they have a very rich automation system, made co-truth by other manufacturers, but only for Biawar and for specific boilers. These are just a few advantages, and there are more.
    There are also disadvantages, burners need good quality fuel from pure wood, so they tend to fall off cheaper pellets with admixture of straw, ground old furniture or construction timber.

    @ziomekorko , this difference of 80 degrees at the exhaust temperature is about 4% efficiency, well, and what about a condensation boiler for pellets, is it worth issuing a bigger "cash"?

    Sstalone - I heard about pellets condensates about two or three years ago. I did not have any contact with the working boiler yet, I only saw at the construction fair a completely folded copy of an Austrian manufacturer for around PLN 27,000. Here, I can not comment on the profitability of the purchase and when the difference will return, especially that this boiler had efficiency at low temperatures only 103%, which in practice will give 100-102%.

    Thank you for explaining the topic..I started to call and I heard that the best in Poland is Lazar and by the way Mrs. very strongly explained to me that Zębiec is not a pellet only coal and the rest, as a friend writes .. I have bitten for smart 15k. I do not know if everyone passes through it but builds the first house and that's how I had ideas starting from the windmills :-) in October, I will have a 85% photovoltaic solar farm for 6,000 zlotys for 4000 zlotys, a 45-liter vacuum tube for 300 tubes (a boiler coil 300 liters, 2x coil) for PLN 10000 (including a subsidy), and certainly a 1000l buffer (I found cheaply with hot water coil (7.8m2 corrugated stainless steel) and solar coil 3m2) and I do not know if 300l should give it up or combine it in series with buffer and how it will be less water 30 degrees it would fly to the buffer ... and I thought the pellet stove would be great as a complement, but here's how we give it 50,000 will be little :-) and I think that the hopper for coal and wood will enter ... I will be heating the collectors with water and the heaters would heat up in the winter instead of the collectors of the stove .. how do you see such an idea? 160m2 cottage, of which ground floor 80m2 and at the top 5 low temperature regulus regulus 55/45/20 house made of suporeksu insulated 15cm polystyrene, roof and ceiling and bevels and ceiling under the stryszkiem insulated with wool 20 and 5 under the profile stairs and wooden ceiling ..

    Hello. Zbigniew - as I wrote above with this boiler I had to deal with once and in addition improved the connection of the boiler room after another plumber. I looked at him and he did not do anything to me, just an ordinary coal-mine with an inserted pellet burner. Temperatures were measured with an exhaust gas analyzer with settings for boilers for solid fuels and biomass, with full power of the boiler working and boiler temperature of around 65 degrees. for your curiosity, let me tell you that the boiler had a flue gas temperature sensor installed, which at the time when I was doing flue gas analysis showed a temperature of about 130-140 degrees, that is, I was lying (I trust my Multilyzer STe flue gas analyzer, because it has never let me down). You as a user of this boiler you have, as you can see, other opinions and observations from everyday use, I only have a few days of experience with this boiler after firing a converted boiler room and adjusting the heating system of my client, which I personally suffice.

    Zbigniew. If you have experience with an agate cog, I am asking you for some contact because I would write a lot about my problem with its setting, or maybe I have poorly run installations.

    Very nice advertising and encouragement, but in the case of these two manufacturers, no one says what costs the user bears during the warranty period, that it is half the value of the boiler where in the case of a companion there are no obligatory paid reviews and first odpalen. Kociol Zebiec was created from scratch as a new co-production. As far as efficiency is concerned, at a temperature of 65 degrees, the temperature for the flue is in the range of 60 to 120 degrees. Such temperatures as a friend writes are how someone defeated the installation or played with the controller.

    At least half of the advisors are producers' distributors, it's great to read and laugh at times.

FAQ

TL;DR: For a 1000 L buffer, prioritize pellet‑dedicated boilers; flue gas 80–100°C vs 160–180°C signals efficiency. "Pellux has mechanical cleaning." This FAQ helps homeowners compare Zębiec Agat 20 kW against rivals, warranties, fuel, and setup. [Elektroda, ziomekorko, post #17417943]

Why it matters: The wrong boiler wastes fuel, raises emissions, and turns automatic heat into constant tinkering.

Quick Facts

Which pellet boiler brands are best if I want low maintenance?

An experienced installer recommends BIAWAR and LAZAR for minimal servicing. He calls them “undisputed leaders among Polish producers.” He places ACV, KOSTRZEWA, GREŃ, DEFRO, and HEIZTECHNIK mid‑tier. He ranks most other brands below average for service and capability. Prioritize brands with strong local support. [Elektroda, ziomekorko, post #17416355]

What do experienced installers say about the Zebiec Agat 20 kW?

One installer inspected an Agat after a problematic installation. At 65B0C water, he measured 160–180B0C flue gas. Comparable boilers at the same water temperature showed 80–100B0C exhaust. He inferred lower efficiency and higher fuel use. He also notes a 10‑year weld warranty but five‑year tightness; leaders give five years on the complete assembly. [Elektroda, ziomekorko, post #17417943]

What do Zebiec Agat owners report about exhaust temperatures?

An owner disagrees with the 160–180B0C claim. He says the flue temperature tracks the setpoint. “With stable operation at 68 degrees, the flue gases fluctuate within these limits.” He considers the unit efficient in daily use. Compare such reports with measured analyzer readings. [Elektroda, Anonymous, post #17697620]

How much should I budget for a complete pellet installation?

Allow PLN 10,000–15,000 for a quality pellet boiler. Add PLN 4,000–7,000 for boiler‑room equipment and labor. With proper setup, users enjoy clean, automatic operation. This budget targets proven, serviceable solutions. [Elektroda, ziomekorko, post #17417943]

Does lowering flue gas temperature actually improve efficiency?

One forum member estimates that an 80B0C exhaust drop equals about a 4% efficiency gain. Treat this as a directional benchmark. Compare boilers at the same load and water temperature. Verify using a flue gas analyzer, not panel sensors. [Elektroda, Sstalone, post #17418265]

Are condensing pellet boilers worth the extra cash?

Condensing pellet boilers exist, mainly from Austrian makers. One seen unit cost ~PLN 27,000. It quoted 103% efficiency at low temperatures, yielding about 100–102% in practice. Payback depends on system temperatures and fuel prices. The poster could not confirm real‑world ROI. [Elektroda, ziomekorko, post #17419012]

Whats special about BIAWAR/NIBE Pellux pellet boilers?

They were designed for pellets, not adapted from coal or oil. They feature mechanical cleaning of tubes and burner. The insulated chamber burns hot, giving clean fumes and little ash. Automation is rich and purpose‑built. “Burners need good quality fuel from pure wood.” Cheap blends with straw or scrap timber can cause faults. [Elektroda, ziomekorko, post #17417943]

Is Gallmet a reliable pellet boiler brand?

One user reports multi‑year reliability. He writes it has worked flawlessly for a couple of years. Single experiences vary by install and service. Consider local parts and technician availability as well. [Elektroda, szejgi, post #17416024]

Will warranty‑period costs surprise me?

A user warns some brands require paid start‑up and periodic reviews. He claims these can total about half the boiler’s value during warranty. He adds that Zebiec does not require obligatory paid reviews and first start. Verify current terms before purchase. [Elektroda, Luk_1982, post #17757459]

Does the Zebiec Agat have Ecodesign certification and is it pellet‑designed?

A poster states the Agat was tested in Zabrze and has Ecodesign. He adds, “it was designed from scratch and it is not a converted coal‑fired one.” Request the lab report from the seller to confirm. [Elektroda, Anonymous, post #17703606]

I cant tune my Agatwho can help?

Seek help from experienced owners or service technicians. One Agat owner asked for direct assistance with settings. Share your full installation diagram and controller parameters. That context helps others diagnose issues quickly. [Elektroda, Maciej użytkownik ze, post #17720250]

How do I properly measure flue gas temperature?

Use a combustion analyzer, not just the boiler’s probe.
  1. Stabilize the boiler near 65B0C and full output.
  2. Set the analyzer for solid fuel/biomass and sample in the flue.
  3. Record analyzer and boiler‑sensor readings, then compare. This method revealed large differences in one case. [Elektroda, ziomekorko, post #17703582]

Could high flue gas temps mean a bad install?

Yes, that’s a common cause. One user notes such temperatures appear when the installation is defeated. Controller misconfiguration can also elevate exhaust temperature. Recheck hydraulics, sensor placement, and control parameters. Then retest with an analyzer. [Elektroda, Luk_1982, post #17757459]

Is Lazar really the best in Poland for pellets?

One poster reports being told Lazar is the best locally. The same caller downplayed Zebiec as non‑pellet. That user leaned toward a SmartFire 15 kW choice. Treat such claims as sales input, not final truth. [Elektroda, Mati19842112, post #17426387]

How do I spot bias in online boiler recommendations?

Be cautious. A user observes many advisors are actually distributors. “It’s great to read and laugh at times.” Ask for test reports or analyzer screenshots when possible. Compare multiple independent experiences before deciding. [Elektroda, Bemx2k, post #17912279]
