Outdated Product
Floor-mounted solid fuel boiler of long burning with an open type combustion chamber, an electronic control system and a pressurization device. It is the youngest model of the Donterm DTM KOT T family, which includes devices with power from 10 to 96 kW. It is positioned as a product of the upper price category, intended for heating residential buildings, as well as small utility rooms up to 80 m². The design features of this model (open combustion chamber) suggest its installation in separate boiler rooms. For normal operation of the device, free air flow and a well-equipped chimney system of a certain geometry and height are required, which provides stable natural draft and completely removes hazardous combustion products. The Donterm DTM KOT-10T boiler is equipped with an enlarged combus...tion chamber that allows you to load large-sized fuel. Air supply is organized around the entire perimeter of the chamber, which makes it possible to efficiently burn fuel and transfer heat to the heat exchanger. Coal, anthracite, wood and briquettes based on it can be used as fuel. The boiler can work on one load of firewood for 6-12 hours, and loading with anthracite will provide 24-48 hours of burning. A durable steel heat exchanger, fireproof cast-iron grates and solid doors ensure reliable and efficient long-term operation.

Model overview based on user reviews  
The Donterm DTM KOT-10T 10 kW solid fuel boiler has received mixed reviews from users. While some appreciate its good heat sink, there are significant concerns about the product's quality and reliability. One user reported a leak on the first day of use, with the manufacturer refusing to honor the warranty. Another user criticized the poor welding quality of the air channel, noting that holes were merely smeared with glue, and described the injectors as ineffective. Despite its promising appearance and specifications, these issues suggest potential buyers should exercise caution and thoroughly consider these factors before purchasing.

Do not buy boilers from this company! Outwardly and in words CLASS!!! And in fact, the TUFTA is FULL !!! I speak from personal experience!
Good heat sink!
Air channel welding quality! More precisely, not welding, but holes smeared with glue! As well as the tightness of the main air channel with which! Injectors generally useless, or rather holes instead of injectors!
