This is wood..I'm sure you guessed that! We heat with it all winter. Sometimes we have to start in October, but this year it was warm until last week and now we're staying in the 20's and 30's...
It goes in here...our wood burning furnace that has a blower that we don't always have to use because this box of heat keeps the house (even the upper level) pretty warm...and since I don't usually have the task of keeping the "home fires burning" I can't explain any more detailed than that. That's Jack's job and he does it great..except when he's winter camping like he did last night!
I do know that once it's done burning it creates a ton of this!
It's hard to regulate the house temp when you heat like this...sometimes it gets too warm and we actually open the windows! But when it's a sustainable cold like we're having now it keeps it comfy and cozy...my electric bill is happy..when the bills are happy, Momma is happy!
