Jaffrey Automatic Wood Stove

[JMoreen]

Good Afternoon,

I have a Jaffrey Automatic Wood Stove that was given to me by a friend. It appears to be in decent shape with no cracks or any major damage. I am having a hard time finding any information on them, and was hoping maybe someone on here has heard of, or is familiar with them? Thanks!

Therefore, I'd hazard a guess that it won't be very efficient with putting out BTUs per pound of wood put in.

Thanks for the info! I certainly would agree on the low efficiency. I’m looking to just have it in the basement for backup heat and to dry the kids winter clothes.

But I’m also leaning towards getting a different stove, I just noticed it has some warping on the sides.

The faded name plate says
"Jaffrey Automatic"
It is a sheet metal box 33" x 33" x 20", with no internal baffles. The output is at the top and back. I added fire bricks at the bottom and sides.
It has a bimetal element on top which controls a flap on the air intake, thus the automatic part.
There is a pre-heat feature: a tube starts at the side air intake and continues to the front where there are 2 air vents at the bottom.
I found it too much heat for my needs so I added more bricks inside to reduce the internal volume and add thermal mass.
It works just fine for my needs.
I'm curious as to when it was made.

BTW any stove is efficient if
1. There is no smoke visible from the chimney
2. The air supply is restricted
3. The temp is 250 or above

Not correct. This.is good combustion .
These are requirements.for efficiency but not enough for demonstrating good efficiency. Efficiency is simply a ratio between heat shed into the room over heat going up the flue. Your points could still be present while 1000 f has is going up the flue (and less heat into the room).

I guess I meant high combustion efficiency.
I extract heat with a bank of thermostatically controlled fans blowing on the stove pipe.
The temperature should be less than 500 degrees for stove protection

Are you talking about stove top or internal flue temps. 500 is completely safe for both of those measurements. The only thing I wouldn't want at 500 would be an external stove pipe temperature.

 

[dhad0]

The thermometer is on the stovepipe, 12" up. Since it is cooled by the fans it should last forever
I like to be conservative.
You can get hot spots that can damage the stove even though the thermometer is OK

 

[stoveliker]

If you have a magnetic thermometer on an actively cooled single wall stove pipe you have no clue how hot or cold it's inside that stove pipe.
