The Woody (CAT)
Woody Eco Cat Ecodesign
 
If you have a big space in your life and you only want to burn wood, then this version of Woody is the one for you. Slim, efficient, clean burning and innovative. The Woody Eco (Cat) is 83% efficient and has a particulate emission figure that is 75% lower than the figure required by Ecodesign standard, thanks to the catalytic converter technology.  We are really impressed with the results achieved using catalytic converters. However they do come at a cost, a lot of wood only stoves cost less than their multi fuel equivalents, as they tend to be more simple, with less components. A catalytic convertor stove includes additional components.
 
Each of these stoves include two (replaceable) catalytic converters. So we thought we should explain what you are paying for and why they are effective.  A catalytic converter consists of a honeycomb type structure with a large surface area which is coated with catalytic materials. As the gases pass over the surface chemical reactions occur, resulting in changes to the composition of the flue gases. In a wood stove, oxidation of the products of incomplete combustion, change the make-up of the gases, for example toxic carbon monoxide and hydrocarbon gases are oxidised into less harmful carbon dioxide and water. These chemical reactions release heat energy. This is effectively a secondary combustion process, as it raises the temperature of the converter to the point where solid soot particles can be burned. For this reason they are sometimes referred to as ‘catalytic combustors’
