Title: Warm weather...
Post by: MNRVGuy on March 12, 2012, 07:53:29 PM
With the warm weather here in Minnesota I am loving the wood consumption (or lack there of) but I am not liking the build up of creosote! How am I ever going to clean that out of my P&M?

Expand your temp differential to like 20 degrees , it should make a longer hotter burn ad get rid of some of it for u

Also, don't put anymore wood in it than you have to have

So, if he expands the differential temp by 20*, does that mean once it reaches its designated shut off, that it will sit and idle until it reaches the 20* diff and fires back up?   ???    Seems one would want a shorter diff so that the fire doesn't sit and idle....this to me is what causes the creosote, but then again...I am still new at this wood burning stuff.   :bash:

Lug, little short fires don't get hot enough to burn creosote from the walls of thue stove.  If your fan only runs 5 mins at a time the internal temp of the firebox don't get where it needs to be, as if it burns 45 minutes it will be roaring inside burning everything up. 

It may in fact create more creosote during those longer idle times, but I can't tell.  Because when it cycles it gets hot enough to burn it all out...

Close differentials are horrible for creosote, remember that ele product guy that wanted to keep his stove within 1 degree at all times, all the experienced members on here told him he was building a creosote factory

Yep I keep a 30* diff all season long. Even with these warm temps I don't have any creosolt issues.
