What do you keep you OWB temp at? I have been keeping ours at 160 with minus 7 cool down. It is doing good just want to make sure that I am not hurting the stove in any way.

There is studies that show more oxygen is present in water at lower temps than 180. 

I run my stove at 165 with a 15 degree swing..   

I think you'll be fine!

Thanks a lot Scott. The OWB is doing so good I was just making sure that I wasn't hurting it in anyway. Seems like if you can run at a lower temp. than it will save on wood consumption.

I tend to think that it does...

 I run mine anywhere from 150 to 185 depending on how much heat I want in my home. I like in a 90 year old house that requires a lot of heat when its cold. The differential setting also varies, the longer burn times are good because it will burn cleaner. However if you ever have trouble with the fire going out you can drop that number down some. I got a bad load of coal in this winter and it wants to go out even when the furnace has plenty of fuel. I dropped the differential down to 4 and it has helped a lot.

Hey yoder, did lowering your diff change your burn times that you could tell

[kybaseball]

So if I keep the temp. at 160-165 with a 10-15 difference is that going to make for less wood usage and a better burn time with less smoke?

[Scott7m]

Definitely burns cleaner with a 15 degree swing in my opinion

I change the difference this morning before I went to work and my wife called and said I think the stove has gone out. I said why do you think that she said I haven't seen any smoke come out of it all day. So that is great.

[Scott7m]

Yep, as long as you have good wood it can go all day and never kick on at all and take right back off when it's ready.

I've never tried burning with a 15 degree differential. I don't think it would work well with coal, when I go back to wood I will try it and see what I think. Long burn cycles do lead to less smoking in my opinion.

I've been burning a little coal, not much, but it works on 15, may work better on 5 with straight coal tho

Can you burn both together?

I was wondering the other day if I might be able to get a lower differential between supply/return temps if I changed my OWB diff from 10 to 5.  Any idea?  I burn hardwood mixed with a couple pieces of poplar (trying to get rid of it!)

I'll say too that I started running my secondary draft wide open, I think it burns more efficiently with it open.  I'll just clean the pipe out every so often unless you guys advise against that.

Yes you can..  It works great when you mix, if you go straight coal, you have to lower the differential to I'd say 5-8 degrees
