Englander 25 PDVC Winter Settings

Harvey Schneider said:

I have measured 350 at the left, top, front corner. That was measured with an infrared device. The rest of the external surfaces are substantially cooler.
My main concern was the vent. That never exceeded 125.

350ºF? The PAH does that on a 1 setting...

I'm questioning whether or not +900ºF is safe to run continuously (as measured at the top center of the glass).

IR measurements at the glass are unreliable. The IR sensor is blinded by the fire. Consequently I have never measured glass temperatures.
Also, 900 seems unrealistic. At that temperature you should be able to see the metal glowing in a dark room.

With apologies to Wikipedia:



According to Chapman's "Workshop Technology" the colours which can be observed in steel are:[1]

Colour Temperature [°C]
Black red (when viewed in dull light) 426 to 593
Very dark red 593 to 704
Dark red 704 to 814
Cherry red 815 to 870
Light cherry red 871 to 981
Orange 981 to 1092
Yellow 1093 to 1258
Yellow white 1259 to 1314
White 1315+

The steel was less, which is why I specified the temperature was taken on the glass. Wasn't aware the glass measurement was unreliable, I've been recording dozens of burns and the glass temperature seems to go up very proportionally to the heat setting. As far as steel, the hottest spot on the stove I can find is just above the door, basically 2" above where I was shooting the glass, and I don't have the measurements on me here at work but it was probably 100-200º less by memory but I'll double check later.

My Jotul likes to take off like a rocket with a full load of good dry wood so I've had a few scary moments with it. I've not seen the steel glow even around 1,000ºF. The baffle and burn tubes were glowing a little though, but they are much hotter.

The other somewhat concerning thing was that my brick hearth in front of the door was getting pretty hot. With the last two woodstoves that sat on it (even with their much higher R-value requirement for the hearth) the bricks wouldn't really even get warm. But with the pellet stove with a much lesser hearth pad requirement the bricks were hot.

I think I left it on a 7 when I left this morning, will check it when I get home. At least the temps are suppose to be a little milder tonight!

singledad Howell here i am using pro pellets right now not sure if you have tried them. They are made up you or the west side. i had my setting on 4 and it was 71 in the morning and was 12 outside

HI, SingledadMI .... Very good ... well .. not so much on the OUTside temps! lol ... I blow by West Branch on the way downstate, about twice a month, for my German music and culture preservation group music and dance practices.

The lowest my upstairs has been 59 .. generally 60-62 in the am, and a 'high' of 66. Most of the heat is getting spent/absorbed in the basement, so far.

I'm using Kirtland pellets, from Boyne CIty, MI. They're local. Hopefully, they'll stay available. through the winter! If this pellet run goes OK this winter, I'll try and stock up in the summer, so I'm not sweating (figuratively speaking, of course), sourcing some! Right now, I'm paying the long dollar by getting 10 bags at a time. That's enough for a week or more. I used the ones at the local Home Depot .. they were 'Michigan Wood' pellets, I think. I always take the names with a grain of salt. Most claim 'premium' or 'best grade', etc, etc. Well, duh ... unless the same company has 2 or 3 grades .. who's going to call theirs 'sh--y grade' or 'less than optimum' ??? Try what you can source easy enough. Seems like many of the posters here are on the east coast. What you find at one place today .. you may not find tomorrow anywhere.
Their kirtlandproducts.com site has a 'Dealer Map' button ... looks like closest to you might be Standish Milling, or Rose City RV Center.

Lowes initially carried the Michigan Wood ones that Home Depot had .. but now carry another. I tried a couple bags, and didn't seem to do so well at the settings I tried, so will use them as last resort.
