Dutchwest 2477 Temps

[chaynes68]

Question on what are a normal range of temps on this stove. Been playing with biobricks and sort of getting to know the stove...kinda new. I have a 15 foot steel chimney straight up with condor temp probe 18 inches up and a surface temp gauge on top of the stove.

Been seeing interior stove pipe temps at 800 degrees (at times, fully reloaded and going well)...ignorance is bliss, however the temp gauge begins the "red zone" at 850 degrees which makes me think that running at these temps is something I should be concerned about.

Wanted some insight from some other owners...thanks.

That's a bit hot. How many bricks are you using at one time? Is it fully dampered down and reaching these stack temps? Try packing them tighter and change the orientation of the bricks 90 degrees, on alternate layers to block air gaps.

I would say this is not how I normally run the stove. Typically it runs about 300-400 stove top with 500-600 stack temps...fully closed up with a load of splits. This morning I loaded it with a combo of splits and biobricks and it peaked at 775-800 degree stack temp fully closed up.

A data point for anyone else playing with biobricks in this stove. With the few embers (very few) I loaded up with a couple pieces of pallet wood with 6 biobricks stacked on top (4 on bottom 2 crossways on top of the 4). Burned for about 2 hours and left me a nice pile of coals for the load of wood mentioned above. Seemed like lots of secondary burning going on.

I am starting to wonder if my firewood is not seasoned enough....the biobricks seem to work MUCH better for me.

Those temps are normal for the stove, ignore the 850 thing, you can go up to 1000.

The chimney is rated for 1000 deg F continuous use, so I wouldn't worry about 800. That's where I run my stove, albeit one with a different secondary combustion system.

There is no doubt that the chimney can handle 1000 all day long....the question is how hot is the stove when you have 800deg continuous probe temps. For me 500 probe means a 700 deg stovetop, if I ran 800probe the stove would be over 1000 for sure.

My stove seems to be the exact opposite. My stove temps almost never exceed 425 degrees, but the stack temps get very hot. As the stove dies down the two temps tend to converge, however the stack temp is hotter.

I suspect the heat exchange is pretty bad on the VC everburn stoves compared to other designs. The probe will ALWAYS be higher than stovetop except perhaps in the coal only, die down stage of the burn. Not a big deal for me because I get all that heat back via a huge single wall flue that goes right though my main living space. But for people that don't have that kind of configuration, the stove is probably a bad choice. If you actually look inside one, you'll see that the secondary combustion chambers are lined with ceramic fiber material and the flow of gasses from there is straight up the flue, doesn't seem like much thought was even put into heat exchange, all focus is on keeping the secondary burn chambers insulated and hot, and draft as strong as possible.

Gord,
so then... what would the stovetop be when the flue probe is 800
