The pollution of the air by a wood central heating system is minimal. Measurements by chimney sweeps prove this. Controlled burning of the fuel takes place. Air pollution is mainly caused by fireplaces and tiled stoves.
Current data from Holzenergie Schweiz show that a good 20 % of domestic energy wood is still available. The surge in demand for wood in recent times will level off again. With the fuel wood, regional value creation is promoted.
Heating with wood is CO2 neutral. What does that mean? When wood is burned, only as much carbon dioxide is released into the environment as the wood also absorbed during its growth. With oil and gas, only pollutants are released.
An important prerequisite for optimal combustion is the correct storage of the fuel; wood log should be well ventilated and stored in a dry place for approx. 2 – 3 years, depending on the thickness. Too moist or dirty lump wood is not only uneconomical to burn, but can also lead to more pollutant emissions at low combustion temperatures.
In principle, an oil tank can be replaced 1:1 and the existing space can continue to be used.
Flexibility and convenience
The modular discharge elements enable flexible configuration of fuel transport from the silo to the boiler. From the discharge screw, the material passes through the safe backfire damper into the combustion chamber. Thanks to the ingenious combustion chamber geometry made of high-quality refractory concrete, even moist fuels up to M40 can be fed into the combustion process. This heavy-duty design promises a long service life and additional safety thanks to a combustion chamber temperature sensor, negative pressure control, and lambda sensor. The systems are tested for a maximum supply temperature of 100° and therefore also offer flexibility for hot water applications. Cleaning and ash removal are fully automatic. The 2 x 50 liter or 240 liter containers on wheels ensure convenient ash disposal.
Clean combustion and CO2-neutral: Wood is a domestic and renewable fuel that burns CO2-neutrally. The UTSD complies with the latest emission regulations and offers optimal combustion. The primary and secondary air is supplied via EC fans. An air flap is also controlled. The combustion chamber is continuously monitored for negative pressure. The EC flue gas fan regulates to changing chimney draft as well as to optimized combustion. Top combustion values are also achieved in partial load operation.
