[AT] another new shop

[Michael P. Maynard]

I have an indoor wood boiler setup, and I just set it up last spring, so my
experience is limited....   Mine has 2 Aquastats hooked to it.  The first
one turns a circulator on when the wood boiler reaches temperature, and
circulates between the wood boiler and the gas one.  The second Aquastat is
a high limit, and will open a designated zone if the wood boiler gets too
hot.  Of course, if this fails, the pressure relief will save you (I know
this, but don’t ask why... ;-)  )  The only time my boiler has gotten too
hot was when I left the ash door cracked open.  I hope to someday heat a
garage with this boiler as well, yanno, someplace to work on Tractors!! :-)

PS Cecil, you might want to hit Empire Farm Days in waterloo on Thursday,
there was a lot of the outdoor boilers there last year.

Cecil, I bet that furnace that blows off steam is hooked up wrong.  The
water needs to circulate ALL the time, you control what heat you draw off
by controlling the secondary circulation at a heat exchanger:  the forced
air fan in my furnace plenum is the only thing the house thermostat
controls.

Hmmm, I wonder how this works with a hot water system like you have?  Maybe
the furnace and the house have 2 separate circulation systems and use a heat
exchanger?  If you hooked directly from the furnace to the radiators in the
house you'd have the problem you described.  A wood fire doesn't just quit
generating heat right away when you cut the air supply off.

The system your friend describes would have to be recharged with antifreeze
all the time.

Yep, mine's all closed with a small expansion tank.

Confusion is a higher state of knowledge than ignorance.
