Solid fuel boiler with automatic loading STALMARK PID VEGAS 50 kW

The STALMARK PID VEGAS 50 kW is a modern solid fuel boiler with a fully automated fuel feeding system, designed with advanced engineering solutions for efficient, safe, and cost-effective heating. The model is ideal for heating large private houses, commercial, and industrial buildings.

Robust construction and energy efficiency

▪️ The boiler body is made using bending and welding technology from 6 mm certified boiler steel, ensuring excellent tightness and durability.
▪️ Mineral wool insulation between the body and the heat exchanger significantly reduces heat loss and increases overall energy efficiency.
▪️ A cast iron retort burner provides stable fuel combustion and high thermal output.

Advanced combustion system

▪️ Automatic screw feeding – stable operation without manual intervention.
▪️ Forced air supply maintains optimal combustion and high boiler efficiency.
▪️ A cast iron deflector above the burner promotes the afterburning of hot gases and even heat distribution across the heat exchanger surface, reducing fuel consumption.
▪️ Ash is automatically pushed to the burner edge and falls into the ash drawer, simplifying maintenance.

⚠️ The combustion chamber must remain closed during operation. It may only be opened for ignition, refueling, or ash removal.

Flue gas evacuation system

▪️ A 45° flue outlet ensures stable and efficient flue gas removal.
▪️ A damper regulates flue gas flow in case of excessive draft — during normal operation, it should remain open.

Fuel hopper and screw feeder

▪️ The fuel hopper allows for a sufficient reserve for long autonomous operation.
▪️ The fuel level should be checked at least once daily.
▪️ Complete emptying of the hopper is not allowed, as it may cause backfire and damage the screw mechanism.
▪️ The minimum fuel level should remain around 30% for safe and stable operation.
▪️ A cast iron screw feeder at the bottom evenly distributes the fuel into the combustion chamber.

Ash drawer and maintenance

▪️ The ash drawer is located at the bottom and collects combustion residue. It is cleaned through a separate door.
▪️ During operation, the ash drawer door must remain tightly closed.
▪️ A slight difference between the temperature on the mechanical thermometer and the electronic controller is normal.

✅ STALMARK PID VEGAS 50 kW is a reliable, energy-efficient, and durable boiler for modern heating systems. Automatic fuel feeding, stable combustion, easy maintenance, and high performance make it an excellent solution for residential and commercial use.
