Solid fuel boiler with manual loading STALMARK JUHAS 20 kW

Efficient Boilers for Water Heating

These boilers are ideal for setting up heating systems in private homes, agricultural buildings, workshops, and commercial properties. They provide reliable and stable heat, operating on various types of fuel, including hard coal, lignite, and wood.

Reliability of Construction and Durability of Materials

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

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

The built-in mechanism with a lever system facilitates the cleaning process of the combustion chamber, reducing maintenance costs.

High Efficiency and Economy

Efficiency up to 80%, allowing rational fuel consumption and reducing operating costs.

The vertical heat exchanger promotes the even distribution of thermal energy.

The enlarged loading chamber reduces the frequency of fuel loading, ensuring longer operation without the need for refueling.

Compatibility with open heating systems, supporting both natural and forced circulation of the heat carrier.

Key Features

Option to choose the combustion mode: top or bottom combustion.

Water-filled grates increase the lifespan and reliability of the boiler.

Spacious loading chamber enhances user convenience.

Movable grate significantly simplifies the cleaning of grates.

Four-way horizontal heat exchanger increases heat transfer efficiency.

Operates without connection to the power grid thanks to natural air draft.

Additional Functions

Thermobimetallic draft regulator - automatically adjusts the air supply depending on the temperature.

RV12 blower fan:

Provides forced air supply to optimize the combustion process.

Allows fuel consumption reduction by up to 30%.

ST-28 controller - maintains a stable temperature of the heat carrier, manages heating and hot water supply pumps, and is equipped with temperature sensors.

Optional: room thermostat for convenient indoor temperature control.

Additional Technical Advantages

The boiler is equipped with a draft damper and secondary air regulator, contributing to stable operation.

The possibility of installing the door on the right or left side, simplifying installation in various conditions.

The use of horizontal flue technology facilitates cleaning, especially in rooms with low ceilings.

Compatible fuel: hard coal, wood briquettes, firewood.

These boilers are a reliable and economical solution for heating systems, providing high efficiency and ease of use.
