Solid fuel boiler with manual loading STALMARK PID 20 kW

Stalmark PID boilers are designed for efficient heating of residential buildings, agricultural structures, workshops, and commercial spaces.

The equipment is equipped with both upper and lower combustion chambers, allowing the use of hard coal, lignite, and wood as the main fuel.

Robust construction and durable materials

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

Water-filled grates eliminate the need for their replacement, providing stable boiler operation.

The lever mechanism for cleaning significantly simplifies equipment maintenance.

Main advantages

Efficiency up to 83% – high energy efficiency.

Horizontally arranged heat exchanger for optimal heat distribution.

Enlarged loading chamber allows less frequent fuel loading and extends the boiler's operation time without refueling.

Operates in open heating systems – suitable for both natural circulation systems and forced movement of the heat carrier.

Key features

Flexibility in use – supports both upper and lower combustion.

Water-filled grates ensure durability and stable operation.

Enlarged loading chamber – convenience in operation and less frequent need to add fuel.

Movable grate – facilitates the cleaning of grates.

4-way heat exchanger – improved heat transfer and high operational efficiency.

Works in open heating systems – simple integration into existing engineering solutions.

Additional options

Thermo-bimetallic draft regulator – regulates air supply depending on temperature.

RV12 boost fan:

Provides forced air supply to the combustion chamber.

Improves combustion process and reduces fuel consumption by up to 30%.

Built-in flue gas temperature sensor – adjusts fan operation for maximum efficiency.

ST-81 z PID controller – maintains stable heat carrier temperature, controls heating system pumps, DHW, underfloor heating, and mixing valve.

Optional: room thermostat – for comfortable temperature regulation in the room.
