 Kommandokenny, your lucky to get that kind of burn times! This unit we have (which will not be here anther winter) used  7 wheelbarrow loads yesterday, not as cold as you either. Loaded it up completely full at 9:00 last night, two wheelbarrow loads, couldn't put another stick in, before 6:00 a.m this morning temperature was way down, just a small bed of coals left looking for more wood. Temperature here was a balmy -20 fahrenheit,no wind either. Our old Empyre liked it's wood, but at least it could handle the load for the night on less wood.

Yep,, that's what this thread is about.
You can see how your consumption adds up.
There have been some small amounts [contested] ;) large amounts wood burned.
I think the cold is the biggest factor for me.
No wind here, to speak of,, and I'm not heating much.
Fella that sold me the stove recommended 4400 over the smaller one they sell.
I said more wood???,, and we're not heating much ,,,,he said trust me :thumbup:

Mr maple can I ask how much area you are heating and what kind of pipes are underground?

my ridgewood 600 stove is heating my drafty 1970 ranch house just fine. Was -12 last night with 20mph winds.

I filled up the front of the stove full with 16 inch pieces. temp was 174 this morning at 9am (14hour burn). There were 2 pieces that werent burned because thy are on the outside endge of the stove. Raked the piece in the hot coals and checked it again at 12noon with a temp of 162.

This one works great. I was burning dry hickory 8 inch piece rounds.

love this stove, 72 degrees inside /DMH

I'm a new OWB owner. I have a Crown Royal model 7400. I burn about 1 cord a week. Is that normal for that size boiler? My house is around 4500 sq ft log built in the late 90s. The boiler temp is 180 and coming into the house is ave 175. Just seems like a lot of wood? Thanks for any help or ideas.

Welcome aboard John, yes that's a lot of wood but it's also a lot of house, your incoming water temp could concern me a bit if it is a short run, can you give us more info on length of pipe, what type pipe and true temps at each end?

4500 square feet at a modest 15 btu per square foot is over 11,000,000 btu per week (at 100 percent efficiency) if we said your stove was 60% efficient (I think that is generous) we could say you would need about 17 or 18 million btu for a week. that is close to a cord of dry mixed hardwood. insulation and  outside temps of course could mean more or less btu are needed per square foot

you will need to add btu for line loss as well (and as slim stated if the temps you related to your outgoing and incoming water are accurate there may be some concern with your underground lines)
