I am wondering what temps either stove should run at without damaging the firebox steel in the future? I have heard guys running 165 high all winter with a 15 degree diff. My question is that most fan forced manufacturers are telling me 170-180 or the stove steel will slowly destroy itself.

Mine is fan forced and I run 170 - 180.  Works great!
Others on here can tell you what to low and to high temps will do to your Furnace

My hardy is on at 164night and off at 174

Fan forced here.. 170-180 here as well.. In fact the new EPA 2 stoves are forced fan draft that Ive seen..What manufacture is telling you that?? Are they talking about the unit being plugged up with creosote due to the lower temps?

I am a 1 month owb owner newbie just trying to find what's best for wood usage and my stove for longevity. I have called all around and I hear 170-180 for temps if I want the stove to last. I was also told by the setup I have that I could run 165-180 for a little longer burn time. I love the opinions so please keep me posted. I am just trying to understand wood usage at 170-180 vs 160-180 and how it differs.

Ive never heard of a owb that has to be at a certain temp for longevity.. On that note I guess you cant shut that boiler down then j/k lol...If anything its the chemicals that you put in the owb water that gives it longevity.. Nothing to do with water temp..Water temp is your choice and what works for you..

Victor,  I don't see there being a big difference in wood consumption at either 170-180 or 160-180.  However, having such a big differential, 20 degrees, can create the potential for your fire to go out esp. when the outside temps are running warm and the boiler has long idle times.  It might also take longer for the fire to heat up and produce good heat.  One other potential problem is letting it get down to 160.  That doesn't leave much room before condensation can form in the firebox (150 degrees).  At least that happens in the gasser boilers.  I don't know if that is a problem with non-gassers.
