Solid fuel boiler with manual loading STALMARK PID 35 kW

Durable Construction and Long-Lasting Materials

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

Advantages of the Boilers

• Energy efficiency up to 83%, reducing fuel consumption.
• A horizontal heat exchanger promotes even heat distribution.
• A spacious loading chamber reduces the frequency of refueling, extending the boiler's autonomous operation.
• Compatible with open heating systems with both natural and forced circulation.

Key Features

• Versatile combustion system – supports both upper and lower burning.
• Water-filled grates ensure long-term durability and stable performance.
• An enlarged loading chamber minimizes the need for frequent refueling, enhancing convenience.
• A movable grate simplifies the cleaning process.
• A four-pass heat exchanger improves heat transfer efficiency.
• Easy integration into existing open heating systems.

Additional Functions

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