The LAMBDA S35 wood boiler by Thermorossi is an excellence in the biomass generator sector, designed to guarantee high energy performance and a reduced environmental impact. Equipped with inverted flame technology, the LAMBDA S35 offers a firebox power of 34.9 kW, ensuring optimal energy efficiency and low emissions, with dust at just 10 mg/m³ and CO at 38 mg/m³.
High Efficiency and Low Emissions: 5-star certified according to EN 303-5:2012 and compliant with European ECODESIGN 2020 standards, this boiler ensures high energy efficiency and minimal environmental impact thanks to low dust and carbon monoxide emissions.
Robust Construction: The LAMBDA S35 is built with high quality materials, which guarantee sturdiness and longevity. The superior weight of the structure is synonymous with durability and reliability over time.
Advanced Combustion Control: Thanks to the two servomotors that regulate the primary and secondary air, and the Lambda probe that detects the quantity of oxygen in combustion, the boiler continuously optimizes the combustion process to maintain the highest levels of energy efficiency.
Efficient Heat Exchange System: The tube bundle with spiral flow expands the heat exchange surfaces, improving the efficiency of heat transfer and reducing fuel consumption.
Modulating Extractor Fan: The continuous regulation of the speed of the fume extractor fan allows the correct temperature of the fumes to be maintained, further improving the efficiency of the system.
Brace function: An exclusive system for preserving the embers allows you to revive the embers of the hearth even after many hours after the generator has stopped, facilitating a new ignition without the need for priming. This system allows you to conserve the embers for up to 12 hours, reducing the frequency of manual ignitions and the waste of fuel.
Benefits for the User
Constant Efficiency: The boiler maintains high efficiency in all operating conditions, thanks to the automated combustion control.
Environmental Sustainability: With low emissions and high efficiency, the LAMBDA S35 is an eco-friendly choice for home heating.
Practicality and Comfort: The ember function and the automated air regulation system ensure comfortable and stress-free use, with easy switching on and reduced maintenance.
LAMBDA S35 by Thermorossi is a heating solution that combines advanced technology, energy efficiency and respect for the environment.
