How to compute Stove output BTU ?

Splits ok green, tougher when dry.

 

Just keep in mind that these type calculations are for equipment sizing, not actual heat loss. In other words it is: 1) Making assumptions on more than 80% of the actual loss calculations. 2) Because of that it is pretty much going to figure the worst case for those figures. 3) Example: My house comes out at 34,000 Btu/h @ 60* on that program when the real number is about 22,000 Btu/h @ 60*.

 

Ah good to know. I'll try to find a few more calculations and take an avg of a few.

 

Yea lots of assumptions.
Add wind & lived in variables, kids , dog door etc , tough to be accurate numbers.

 

Yea I agree. I've looked at 3-4 different calculations and I come up with anywhere from 50,000-60,000 btu/hr loss for my home with a 60-80F temp differential. That is worst case scenario but still nice to have some numbers to better understand where I'm at with my heating needs.

 

Hard to imagine 60,000 BTU heat loss with the normal Ohio weather.
Must not be much insulation.

I know here when it's below zero° & 40 + mph wind.
The stove burns a load fast . Extra draft & max heat needed.

Can feel air leaks around the windows on the windward side.

 

Dave,
We are not getting enough detail on your loads, times, splits, wood type, OAT, inside temp, burn times.....

Oh, wait,.... Now I see it!



Great thread!

 

Keep in mind I'm heating 2500 sqft plus a 900 sqft finished basement. The house was built in the mid 90's with good insulation. This house holds heat better than my old 1600 sqft home built in the late 50's.

 

And that 60,000 btu loss is with a 70F temp differential. Ohio winters are no Alaska winter but 0F outside is cold no matter where you are.

 

+1
I call anything below +10 ° cold. Add wind & it can be brutal.

 

I call anything below 60 COLD!!!!!!!!!!
