I believe I'll not comment on the personal attacks, but will say, :
LOOK AT THE DATE of a thread and read the entire thread/subject before you hit reply and add a comment..
This thread started in 2007 !!
IF a person reads the ENTIRE THREAD you will see that the drift of the thread changes over the years..
To comment on the first page or two of heated and emotional posts is like going to a 2007 political thread and commenting on it 6 YEARs later..
What isn't evident in reading this thread from the begining is that at the time, in 2007, there were very few people on the forum,
many first time burners who wanted a cut and dry setting for a MPD.. 'how far should I close the MPD.. I lost my fire', I can't keep the fire hot',
I burnt up all my fire in 4 hours, and the house was not warm etc,etc etc.. A baro is a set it and forget it control for an over-drafting chimney..
So a baro was strongly advocated for inexperienced burners.
As the years go by, as a burner gains experience, and mpd is often added with much success, Or a baro is tried with success or sometime no success.
A baro never adds draft to an under-drafting chimney. The entire draft control and exhaust airflow control issue is badly misunderstood by many.
This entire 6 year thread can be distilled down to a few lines:
MPD's work well for an EXPERIENCED burner, and for burning WOOD, and for NON-AIRTIGHT stoves.
They also work well with stoves with a BUILT IN thermostatic draft control, like most Hitzers, some warm mornings and others.
If your stove is not airtight, then a MPD is a necessity, because your stove is out of control with air leaks.
If you can't shut down the fire with the stove's air controls in the stove's body or doors, then your stove leaks, is not airtight,
and needs the 'bandaid' of an MPD in the flue pipe
OLD stoves, like the base burners, base heaters, Oak with indirect draft need a stronger draft, and even have 'check dampers' which
must be used with caution for the potential of CO leaks into the living space.
People who got on the forum and wanted a set it and forget it draft will use a baro with success. Many modern stove manufacturers
state to NOT use an MPD, but to use a BARO to control draft. These modern stoves, if maintained, are airtight and are able to
control exhaust flow rates. with their ashpan door draft controls, therefore an MPD is not needed.
The combination of an MPD followed with a BARO above the MPD is the ultimate control.. ONe controls draft and the other
controls exhaust flow rate through a leaky stove.
Over the years, many people have discovered that they do just fine with one or the other or with both or with neither..
The entire issue of draft control vs exhaust flow control is badly misunderstood by many.
