[Stoves] Extreme wood stoves

Dear Wood Burners

 

Lovely selection of stoves from ancient Greece to today.

And more on the new EPA regulations for wood stoves:

You will notice that there are different emissions allowed for stoves that
are tested 'according to EPA' and stove tested using 'cordwood'.  This is
important. There have been complaints that stoves are being tested in a way
that does not reflect use (decontextualized testing). It is evident that
people can build stoves that will pass the PM2.5 emission test but have a
very different 'real' emissions rate because the test is so different from
what people do when they get it.

 

Sound familiar?

 

The main difference is the fuel burned. Round chopped wood is not the same
as machined 4x4 inch or 2x4 inch cut timber, and burns differently which
affects emissions. 

 

The move is towards testing using conditions that reflect normal use
(contextual testing) and the emissions allowed are higher than before. This
is not happening immediately, but will come eventually. 

 

Strangely coal stoves and multi-fuel stoves are not covered by the new
rules, but must not advertise that they can burn wood or pellets. Because it
is rather obvious that a multi-fuel stove can burn wood, it seems the plan
is to ban multi-fuel stoves, a simple, bureaucratic solution.
