Boilers for solid fuel, wood, coal, pellets and gasification boilers
Solid fuel boilers always meet the requirement for efficient and economical heating. Whether operated as an additional or complete heating source, whether with wood chips or wood pellets: ATMOS has a complete range for wood heating. Your decision will always be reliable.
Mandatory equipment for boilers intended for closed combustion systems includes protection against overheating - a cooling loop or a pressure safety device. Boilers intended for open combustion systems do not need to be equipped with a safety device. Boilers can be used for systems with both gravity and forced water circulation. The loading opening is structurally adapted for loading wooden logs.

Frequently Asked Questions
- What is the difference between a classic and a gasification solid fuel boiler? A classic boiler burns fuel directly on a grate, while a gasification boiler first gasifies the fuel in a vacuum chamber and then burns the resulting wood gas – achieving higher efficiency and lower emissions.
- What fuel can be used in these boilers? Depending on the type of boiler, wood, coal, wood briquettes, or a combination thereof. The fuel recommended by the manufacturer should always be followed.
- Does a solid fuel boiler need a storage tank? For gasification boilers, a storage tank (heat accumulator) is recommended – it increases combustion efficiency and extends the boiler's service life.
- Is it necessary to protect the boiler against overheating? Yes, boilers in closed systems must have a cooling loop or a safety device against overheating; open systems do not require this equipment.
- What kind of chimney do I need for a solid fuel boiler? A lined chimney is recommended, preferably made of stainless steel, with a diameter corresponding to the boiler's outlet.
