Emissions from the Yorkshire are so low that it very easily complies with the clean air act. Independent laboratory tests show efficiencies of over 70% on a whole range of fuels including wood.
All this has been achieved on the Yorkshire without using catalyst combusters, which are very expensive to replace and can easily become damaged if coal or impure wood is burnt. Cleanburning is also better.
The Yorkshire Stove uses the Downburning system where air comes in at the top, the smoke is pulled downwards, so that the smoke [which is tiny particles of unburned fuel] is forced through the very hottest part of the fire and so burns away as air is introduced through the afterburn air inlets at the rear of the fire – giving more heat for less fuel therefore much cleaner combustion.Got A Question?
