BURNiT NWB PRIME 70 - Wood boiler (70 kW)

70 kW wood boiler for commercial and larger heating projects

The BURNiT NWB PRIME 70 wood boiler (70 kW) is designed for heating projects that require a powerful wood-fired heat source. This model is suitable for commercial buildings, larger workshops, agricultural spaces, halls and installations with high continuous heat demand.

Clear positioning for larger buildings

While lower output models are more suitable for homes, outbuildings and smaller workshops, the 70 kW version is aimed at larger project-based heating systems. This includes larger buffer tanks, multiple heating circuits and hydraulic systems with a higher continuous load.

Electronic control with fan operation

The BURNiT NWB PRIME 70 features electronic control with fan operation. This allows the combustion process to be controlled more accurately and helps keep heat output stable according to system demand.

Suitable for logs up to approx. 50 cm

The large combustion chamber and wide loading door make it easy to load logs up to approximately 50 cm. This is especially practical for systems that are operated regularly and for longer heating periods.

Three-pass flue gas path for efficient heat use

The three-pass flue gas path guides the flue gases through the boiler for a longer route, allowing more heat to be transferred to the heating water. In this output class, efficient heat utilization is an important factor in total system performance.

Full water jacket around the combustion chamber

The full water jacket around the combustion chamber supports effective heat transfer. This allows the boiler to integrate well with buffer tanks, hydraulic manifolds, radiators, air heaters or other heat distribution systems.

Prepared for pellet, oil or gas burner extension

The BURNiT NWB PRIME 70 is prepared for extension with pellet, oil or gas burners. This provides additional flexibility if alternative fuels or supplementary heat sources are required later.

Safety and certification for professional installations

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