BeGreen,
Thanks, always glad to help the family of Fisher Bears.
Been busy as a termite, but have not forgot about you. Been reading the links that you gave, plus the links that your links linked, & such makes for a very long reading, especially government links. Anyone having insomnia? Just read 5 or more pages of a government report & your sleep disorder is history. Just be sure to put down pillows on either side of your chair for a safe landing before reading.
Not to hijack Boyd’s thread, but since it is pertinent to his situation about emissions thought he might like to see this. The following EPA Phase 2 (EPA p2) heater article is an eye opening government admission about a suppressed
fact.
The following is taken from page 3 of 4 at
http://burningissues.org/bi/pdfs/gov.pdf#search="fisher wood heater"
<snip>
"The particulate emissions for stoves in Portland homes were, on average, higher than the stoves in Klamath Falls homes. This result is consistent with the average higher fuel moisture content & burn rate characteristics of the Portland portion of the study as compared with the Klamath Falls portion of the study.
The particulate emission factors for the certified phase 2 stoves evaluated in this study appear to have become higher with use, but after about 7 years, on average, the certified phase 2 stoves still have lower emissions than uncertified conventional stoves (Table 1)."
<snip>
Note that in Table 1 the “conventional“ heaters were
only twice as dirty as the EPA p2 heaters,
not 10 times as is to often claimed. And that the government failed to identify make & model of the “conventional” heaters. As you well know there is a difference between conventional heaters. A Franklin is
not a Fisher peer in performance.
And when a Franklin bounces off a pickup the litter crew merely picks up the pieces. But when a Fisher comes off the driver is in serious trouble with “Homeland Security”, they have just created a tank trap on a public access road & serious weight lifters are needed to extract the heater. But the Fisher would merely require some sandpapering & a can of high temp black paint to be ready to heat again. Like a welder once said; “A 5/16” steel heater is
definitely heavy metal!” :coolsmile:
Yes, things would have been better for the EPA p2 units had the owners maintained their heaters, but that makes my point. In real life there is only a modest improvement in EPA p2 heater emissions over "conventional" heaters.
And the following article goes to what I have stated earlier, the drier the wood the better. By using dry wood a “conventional” wood heater becomes a large pellet burning machine. Yes, the efficiency of a conventional will not be as high as a pellet, but then the pellet owner pays for such in electricity, maintenance costs, I.e. fan & auger motors, baffles, ups standby for power failure, etc. The Fisher owner merely gets the heater into the run temp & enjoys. If the power goes out, no problem.

Thus any wood heater’s operation has 3 basic requirements for a successful operation. The moisture content (mc) of the wood, preferably below 10%, the fire-up & run temp‘s. If an
inexperience operator will
strictly observe those parameters then I dare state that their heater’s performance will exceed that of an experienced operator, whose Liberty Lopi is fed wood with a 20% mc & has no thermometer. Si
?
Boyd, Karen, et al, some more helpful articles that make my point about mc in wood.
