Yes it can.

We care about the environment. We feel strongly about the environment and our common future. For many years, the manufacturers we use and recommend have been working intensely on environmentally friendly clean burning stoves for the benefit of the environment.

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

The stoves we sell are some of the most clean-burning stoves in Europe with unique fire chambers and air channels meaning that CO2 and harmful particles are reduced to an absolute minimum.  They are all tested in accordance with all applicable regulations  here in the UK and Europe with many being Defra Approved for Smokeless Zones.
