ATON Compact 12.5E 12.5 kW
 | Outdated Product Non-volatile single-circuit gas heating boiler of low power with a closed combustion chamber, simple operation and relatively compact overall dimensions. It is one of the medium models of the popular ATON Compact line, which includes gas boilers with power from 7 to 16 kW. The design of this model allows it to be used in heating systems with natural circulation. At the same time, due to the closed (turbocharged) combustion chamber, the ATON Compact 12.5E boiler does not require a complex chimney system and can be installed directly in residential areas (the removal of combustion products and air intake is carried out using a special horizontal two-pipe flue duct (60/100 mm) through an external building wall). This model uses an advanced welded steel heat exchanger made of special profile f...ire tubes. The zigzag channel in the pipes provides intensive mixing of gases during movement, which, in turn, improved heat transfer and reduced the size of the boiler (dimensions allow installation in any small apartment). The heat output of the boiler is sufficient for space heating up to 94 m², and its efficiency reaches 90%. Equipped with all necessary safety systems (for pressure, overheating and flame). Able to maintain performance at low pressure in the gas line (up to 13 mbar). |

Model overview based on user reviews
The ATON Compact 7E 7 kW is a compact and powerful parapet gas boiler designed for small spaces, making it ideal for rural areas where electricity outages are common. It features high-quality Italian burners and operates without electricity, drawing air for combustion from outside and venting flue gases through a wall, eliminating the need for a high chimney. Installation is straightforward but requires a significant hole in an external wall. Users appreciate its affordable price compared to imported models and its effective heating capabilities. However, some users note the need for better installation instructions and diagrams, as well as a potential design flaw that causes a quiet crackle upon startup. Overall, it is a safe and efficient choice for those needing a reliable heating solution in areas with limited space and frequent power issues.
Pros
Cons
At first glance the device seems decent, but the description is composed with technical errors. To understand everything, it will be necessary to see it in "real life". a large opening in the wall, The description is poorly composed, incomplete for understanding the merits of the design. |
I needed a compact gas boiler for a small house. The size was very important, as there was very little space for installation. I chose from parapet boilers of domestic manufacturers. Heats up quickly, quite powerful for such a small size. It takes air for combustion from the street, and removes flue gases there. A standard high chimney is not needed. The boiler emits combustion products through a combined chimney directly through the wall near which it is installed. Equipped with high-quality Italian burners Polidoro. It does not require electricity to work. I installed it in a rural area and the problem of electricity here constantly arises. The power line is overhead and in strong winds, sleet and icing, outages occur frequently. Safe. All automation in this boiler is Italian. The price is super. Compared to imported boilers, the price differs significantly, and it heats no worse. Installation is pretty simple. True, the wall has to be disfigured, but there is no way without it. It is possible to put such a boiler only on an external wall. Otherwise, you can’t make a smoke vent, such is its design feature. Yes, and a hole in the wall will have to be made serious. Be prepared for this. Immediately after switching on, a quiet crackle is heard, apparently, the design expands from heating. After 5-7 minutes it subsides. |
If a video ad shows hand-to-hand joints, can you imagine what they will send you in the mail? Beautiful white and red paint from afar... The message of the boiler is a complete drawback ... Although if it were teleported to 1917 .... use ATON Compact 10E less than month |

- In the name and description, the device is mounted on the wall. In the diagram, the device is shown installed on the floor.
- A 240mm hole needs to be made in the wall, whereas the diagram shows a minimum size of 230mm. The diameter of the air exhaust pipe is 100mm. Why then is a 230mm hole required in the wall? What fills this space? The description and diagram do not match each other. The diagram is incorrect and inconsistencies need to be removed.
- A diagram of the device installation with dimensions indicated in the table should be added to Table 2 for proper understanding.
