Solid fuel boiler with manual loading STALMARK JUHAS 40 kW

These boilers are an excellent choice for setting up heating systems in private homes, agricultural buildings, workshops, and commercial spaces. They provide stable heat supply and can operate on various types of fuel, such as hard coal, brown coal, and wood.

Robust Construction and Durability

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 prevent wear and tear, ensuring uninterrupted boiler operation.

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

Cost-Effectiveness and High Performance

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

A vertical heat exchanger ensures even heat distribution throughout the space.

An enlarged loading chamber allows for less frequent refueling, increasing autonomous operation time.

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

Key Advantages

Choice of combustion modes: top or bottom burning.

Water-cooled grates extend the boiler's service life.

A spacious loading chamber enhances ease of use.

A movable grate simplifies ash removal.

A four-pass horizontal heat exchanger improves heat exchange efficiency.

Operates without electricity, relying on natural air draft.

Additional Features

RV12 fan:

Improves combustion by providing forced air supply.

Saves up to 30% of fuel.

ST-28 controller:

Maintains the set temperature of the heat carrier.

Manages heating and hot water supply pumps.

Optional: Room thermostat for convenient temperature control.

Technical Features

Built-in draft damper and secondary air regulator ensure stable operation.

The door can be installed on the left or right side, simplifying installation in various conditions.

Horizontal flues make cleaning easier, especially in rooms with low ceilings.

Supported fuels: hard coal, wood briquettes, and firewood.

These boilers are a reliable and cost-effective solution for heating systems, offering high efficiency and ease of use.
