my idea for a insert fix

[husky455rancher]

ok when i got my insert 3 years ago i had to cruch the flex pipe quite a bit to get it up the chimney. this year i fixed the problem and the pipe if totally round with no restrictions.


the problem im having now is that i have a totally uncrushed stove pipe is the stove cant throw the heat like it used to. the last 2 years i always left the draft totally closed and the house would be 70-72ish. now im leaving it wide open and it cant get outta the mid 60's. so basicly i cant keep the house at an acceptable level of warmth. so next time i shut it down totally probly thanksgiving night or so. im gonna install a damper in the pipe. basicly by crushing the pipe before i believe i created a damper and when i removed it thats whats causing my heat loss. does that make sense to anyone?

Sounds about right to me...

What did the pipe look like inside before you straightened(rounded) it out?How big is the pipe? I would guess that you are using 8" or larger pipe and getting too much draft.I think I would rather you use a 8-6" reducer than crimping it, but you will have a better idea by looking at it.

I think you should also pick up a thermostat to accurately guage what is going on.

In my case...8" produces too little draft...I get great heat, but not the best of draws...have to burn a hotter fire than I'd like...which in turn uses more wood.

I would benefit from a smaller flue...this house is tight as a drum, I leave a window open an inch or so in the insert room unless I'm running the furnace fan...it has it's own 8" outside air intake and swing damper.

pipe is 8" i think, ill check for sure when i pull it out. but i literally crusshed the pipe in half to get it up the chimney when i first did it.

Im no expert but I think the 8" is too big for your application.Ive got a Sierra with 6" fitting into 6" liner up the chimney and it handles all i can throw at it.

like i said ill check to be sure but its whatever the sive the pipe is on the insert i didnt jump it up to 8 or anything like that.
