BURNiT NWB PRIME 25 - Wood boiler (25 kW)

Wood boiler for powerful heating systems

The BURNiT NWB PRIME 25 wood boiler (25 kW) is designed for heating systems where a reliable wood-fired heat source is required. With an output of 25 kW, this boiler is suitable for residential buildings with higher heat demand, workshops, outbuildings and other applications where standard heating solutions are not sufficient.

Professional foundation for installers

This model within the NWB PRIME series combines output, controllability and practical usability. For installers, it is especially suitable when a wood boiler needs to be integrated into a complete heating setup with buffer storage, controls, safety components and heat distribution.

Electronic control with fan operation

The BURNiT NWB PRIME 25 is equipped with electronic control that operates the fan. This allows the combustion process to run in a more controlled way and helps match heat output to the current system demand. The result is more stable performance and better manageable firing behaviour.

Practical loading with logs up to 50 cm

The large combustion chamber and wide loading door make it easy to load logs up to approximately 50 cm. This improves user convenience and makes the boiler suitable for daily operation. The combustion chamber is designed for efficient heat transfer to the heating water.

Three-pass flue gas path and water jacket

The three-pass flue gas path helps maximize heat extraction from the flue gases before they leave the boiler. Combined with the water jacket around the combustion chamber, the generated heat is transferred efficiently to the heating system.

Flexible extension with additional burners

The BURNiT NWB PRIME 25 is prepared for extension with pellet, oil or gas burners. This keeps the heating system flexible if fuel choices or project requirements change in the future.

Safety and certification

The wood boiler is equipped with important safety components, including an STB emergency thermostat, a 3 bar safety valve, a safety heat exchanger and an air inlet valve. The NWB PRIME series is tested and approved according to EN 303-5.

Application with buffer tanks and complete system design

For a reliable wood-fired heating installation, correct system design is essential. This includes sufficient buffer capacity, proper hydraulic integration, suitable controls and reliable heating circuit protection. The BURNiT NWB PRIME 25 provides a solid foundation for this.
