Wood burning boiler Balkan Energy 50, 50kW

Product Features:

Construction:  

- The boiler body is made from high-quality 5mm thick steel.  
- It features a large combustion chamber with a large heat exchange surface and low impedance for more efficient draft.  
- A large door allows for easy loading of large pieces of wood.  

Efficiency:

- The combustion chamber is ribbed and designed with a triple flue path to maximise heat exchange.  
- The third flue path features large-diameter pipes to control the exhaust gas flow effectively, with turbulators to regulate the speed of the exiting flue gases and optimise the efficiency .  
- The combustion chamber is fully encased by the mantle to enhance heat exchanging efficiency.  
- The boiler is externally insulated with dense ceramic stone wool, designed to withstand high temperatures.  
- A thermostatic draft regulator automatically adjusts the air supply for combustion by opening or closing a flap on the bottom door based on the boiler's temperature.  

Additional Features:  

- A ribbed combustion chamber and triple exhaust path enhance heat exchange.  
- The last exhaust path uses large-diameter pipes and can add turbulators to adjust the exhaust gas speed.  
- The lower door is designed to accommodate a pellet burner with an optional neck flange.  

Safety Features:

To ensure safe and reliable operation, several safety components are required:  
- A mechanical chain wood boiler thermostat (traction controller).  
- A 3-bar pressure relief valve (included with the product).  
- A heat expansion cooler located at the back and top of the boiler must be connected to the water supply network using a thermal valve with a remote sensor (not included with the product). In case of overheating, this system releases water into the heat exchanger, dissipating excess heat into the environment.  

Certifications: 

This product complies with EN 303-5 standards and is CE certified.
