Solid fuel boiler with manual loading STALMARK PID 25 kW

Stalmark PID Boilers – Reliability and Efficiency for Every Home

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

With a combustion chamber that supports both upper and lower burning, the system allows the use of hard coal, lignite, and wood as primary fuel sources.

Durable Construction and High-Quality Materials

• The body and heat exchanger are made of certified P265GH boiler steel with a thickness of 6 mm, ensuring durability and a long service life.
• Water-filled grates eliminate the need for replacement, guaranteeing stable operation.
• A lever-operated cleaning mechanism simplifies maintenance.

Key Advantages

• Efficiency of up to 83% – high energy performance.
• Horizontally positioned heat exchanger for even heat distribution.
• A large fuel loading chamber reduces refueling frequency and extends operational time.
• Compatible with open heating systems, suitable for both natural and forced circulation.

Main Features

• Flexible combustion system – supports both upper and lower burning.
• Water-filled grates for enhanced longevity and reliability.
• Enlarged loading chamber – fewer refueling intervals.
• Movable grate for easier cleaning.
• 4-pass heat exchanger for improved heat transfer and efficiency.
• Works with open heating systems for easy integration into existing setups.

Additional Features

1. Thermo-bimetallic draft regulator that automatically adjusts air supply based on temperature.
2. RV12 Blower Fan:
   • Ensures forced air supply to the combustion chamber.
   • Optimizes combustion efficiency and reduces fuel consumption by up to 30%.
3. Flue gas temperature sensor adjusts the fan operation for maximum fuel efficiency.
4. ST-81 z PID controller maintains a stable heat carrier temperature and manages heating system pumps, domestic hot water, underfloor heating, and the mixing valve.
5. Optional: Room thermostat for convenient indoor temperature control.
