[Greenbuilding] firewood moisture content - a question for Norbert perhaps

I for one would LOVE to hear the responses to your questions, Sacie.  I am
also heating ONLY with wood, (in my Morso 3610 stove, thanks to the info I
gleaned from this List) and have some great oak, although it is green.  To
balance it off, I have a pile of 4-year old oak that seems to be making a
great mix.  But....I'd love to be in this loop.


BTW, according to some 2010 numbers, I am at about 4000 HDD. 


Thank, Kathy Cochran

Since we heat our home primarily with wood, this is most interesting to me
(though possibly better for another forum).  What is the stove you or Reuben
use and what is the space you heat that allows just one or so burns a day?
I am presuming good insulation.

And what is it you do to create a very hot fire from the beginning--would
appreciate the specific times involved in each step when you describe your
process.  Starting from coals of the night before....or from scratch...

And of course I would be happy to have this info off line if the rest of you
would just as soon not talk about building efficient fires on this
greenbuilding site.

Where is Norbert btw?  We actually haven't heard from him for months.  His
responses are spot on.

Thanks,  Sacie

Me too.  Reuben once mentioned he lights his fires several times a day
only; from this I infer he lets it go out, then later, as the house
cools, fires up the stove again.  Is this correct, Reuben?  If so, how
do you prevent creosote buildup in your chimney?  Or maybe you simply
clean it several times a year?


The wood I am burning this year is particularly wet, so perhaps I will have
something to say on the matter come spring.  That said, my chimney has never
needed cleaning; I clean the stove pipe, and the basement clean out, but the
flue has always been clean. I burn almost as hot as possible, though at most
one fire per day.  I contend that creosote buildup comes from burning too
cool while in the initial stages of wood burning (i.e. before the wood is
reduced to coals).  I can imagine Reuben being able to burn multiple small
fires without creosote buildup if they are hot enough.

Thank You Kindly,
