We care about the environment

Environment and future

We feel strongly about the environment and our common future. For many years, HETA has been working intensely on environmentally friendly manufacturing of clean burning stoves for the benefit of the environment.

All HETA stoves have impressively high burning value over 80 percent, so you get more out of your firewood, and polluting gases are burned off before leaving the chimney.

HETA’s stoves are some of the most clean-burning stoves in Europe. They are tested in accordance with applicable regulations in Norway, Denmark, Germany as well as the new European standard.

HETA’s completely unique fire chamber and air channels mean that CO2 and harmful particles are reduced to an absolute minimum.

Wood energy is CO2-neutral

Wood is the world’s most climate- and environmentally friendly raw material. Among other things because heating with wood is CO2-neutral – unlike fossil fuels such as oil, coal and gas. As such, heating with wood does not contribute to the greenhouse effect.

Wood does not generate more CO2 when burned than when it decomposes as part of its natural cycle in the forests. When utilising wood energy, fossil fuels become unnecessary.

Reducing CO2

The unique sizing of the fire chamber and air channels in HETA stoves reduces CO2 and harmful particles to an absolute minimum.

HETA’s modern combustion technique Clean Burn is particularly effective and removes soot particles on the glass door and through smoke vents. A healthy and comfortable radiation heat starts up immediately through the large glass windows when you light your stove and shortly after the convection system starts spreading the heat and cosiness in the room and the adjoining rooms.

In addition, many of our products come with heat-retaining stone – soapstone, sandstone, granite or ceramic – retaining and slowly releasing the heat for many hours.

Clean Burn

HETA’s Clean Burn combustion technology ensures that combustion air is free-flowing and feeds combustion without any resistance. The preheated tertiary air supply burns the remaining gases before the smoke enters the chimney, making it an important factor for environmentally friendly combustion. The hot convection air is the air that is distributed to the surrounding area, which – together with the radiant heat from the glass window – constitutes the direct heat source.

The heat is better exploited and you can enjoy the view of the flames through the large glass window in the door – completely without soot.
