Solid fuel boiler with manual loading STALMARK JUHAS 25 kW

Efficient Water Heating Boilers

These boilers are an optimal solution for creating heating systems in private homes, agricultural buildings, workshops, and commercial spaces. They guarantee stable and reliable heat supply, operating on various types of fuel, such as hard coal, brown coal, and wood.

Reliability of Construction and Durability of Materials

The body and heat exchanger are made of certified boiler steel P265GH, 6 mm thick, ensuring resistance to extreme loads and a long service life.

Water-cooled grates eliminate the need for replacement, ensuring uninterrupted boiler operation.

A built-in lever mechanism simplifies the cleaning of the combustion chamber, reducing maintenance costs.

High Efficiency and Cost-Effectiveness

Efficiency reaches 80%, minimizing fuel consumption and reducing operating costs.

A vertical heat exchanger ensures even heat distribution.

An enlarged loading chamber reduces the frequency of refueling, extending autonomous operation time.

The boilers are compatible with open heating systems, supporting both natural and forced circulation of the heat carrier.
