I thought I read somewhere if it's set too low your firebox will sweat and rust out. I could be wrong

Yes they will

There is a nc here at my buddies place, an NBC 175 that rusted out due to some low return temps

    Do You know what the temp was set at?

Customer was set at 165 with a 10 degree differential, but his pump was undersized and delta t was likely 50-60 degrees, about 40 more than he could stand

[Scott7m]

when its still half way warm 170 to help reduce boiling, 185 when it gets cold, I have baseboards and need high temps to get hear, even tried 190 when it real cold last winter.

Reduce boiling??!

Scott how many years did your buddy get out of the one that rusted out?

[Scott7m]

It was an 09 model I do believe.

[victor6deep]

Was he the guy heating his pool with it?

[Scott7m]

Nope, just home and hot water

[victor6deep]

How far was his stove from his house? I know way too many people that have made 20yrs running 160 with no issues. Maybe his stove was built on a Monday.

[Scott7m]

Makes no difference if his stove was 10 feet or 300, delta t was the same

If there pumps are oversized they may be able to get by with 160, but u were telling me last season that all your buddies fire boxes were completely caked with creosote?

[victor6deep]

I will believe it when mine rusts out.

[Scott7m]

Excellent approach...  maybe then you can trade a couple loads of wood for a new stove   

I really don't see what you think your gaining?  I've got numerous messages here from ya I was just reading where you were talking about how nasty there fire boxes were and how you weren't gonna let yours get like that and at the time you were running hotter and proclaiming the benefits of it?!   I am lost.

[victor6deep]

I am lost.

Hey Scott, so the lower the delta T the better?

[Scott7m]

If your return water, with all heat extraction taking place needs to be over 140.  Most all boilers whether gas, coal, oil, you name it are designed for a delta t around 20 degrees.  The system design is the dealers part to get right.   Properly sizing the pump and line combo for the job at hand, its why I frown on doing a one size fits all pump on a stove.

It does a fair amount of steaming with audiable bubbles when it burns trying to get to 185 when its 50F outside.

[Scott7m]

Hmm....  Interesting. 

Do u ever add water to your stove
