Frequently asked questions?

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 isCO2 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.

Product description

Flexibility and comfort

The modular discharge elements allow a flexible design of the fuel conveyance from the silo to the boiler. From the discharge screw, the material enters the combustion chamber via the safe burnback damper. Thanks to the sophisticated system of combustion chamber geometry, made of high-quality refractory concrete, even moist fuels up to M40 can be fed to the combustion system. This heavy-duty design promises a long service life as well as additional safety thanks to combustion chamber temperature sensor, vacuum control and lambda probe. The units are tested for a maximum flow temperature of 100° and thus also offer flexibility with regard to hot water applications. Cleaning and ash removal are fully automatic. Thus, the 2 x 50 liter or the 240 liter container on wheels ensure convenient ash disposal.

Clean combustion and CO2 neutral: Wood is a domestic and renewable fuel, which burns CO2-neutral. The UTSD complies with the latest emission regulations and provides optimal combustion. The primary and secondary air is supplied by EC fans. In addition, an air damper is controlled. The combustion chamber is also constantly monitored for negative pressure. The EC exhaust fan responds to a changing stack draft in the same way as it does to optimized combustion. Top combustion values are achieved even in partial-load operation.

  • Reversing the motors
  • Sophisticated combustion chamber geometry
  • Combustion of moist fuels up to M40 possible
  • Automatic ash removal
  • Variable and therefore ideal positioning of the ash containers
  • Achieves the highest boiler class 5
