Was just wondering if any one here had any thoughts on the difference between splitting logs or just cutting them to lenght for the firebox? Does one seem to burn better in certain stoves or what? Just a question. Thanks.

non gasser, home made,leave em round and never split unless they don't fit in the door

Well Jack that is really up to you..Its on you on what you want to handle...My boiler can hold a 42 inch log..I burn 24 inch wood..I use to do the bigger wood..Thinking bigger length is better... Well 24 inch has the same burn time...So on that note..I was wasting wood by burning the longer length wood..Overall theres really no right or wrong way with the logs....Its really basically on what you want to handle..I also think of the guy that if i went away for vacation..I don't want him to deal with huge wood to load it..

jack my boiler is natraly asperated and it still likes the hole log at night time when it gets cold.... I normally put 2 big complete logs on bottom,then smaller complete logs on top of that and split peices orlittle branches on very top.....not that mine holds alot it has a 9 cubic foot fire box but still i get 9 1/2 -11 hours of burn time in single digits and 8-9 hours burn time at -16f.... but i do split the really big ones anything over 14 inch so my wife can handle the wood when i am not home.....

I was wondering that too I am thinking about splitting small so the wood can season faster so I would have less smoke but those big ones seem to burn a while
-
The big rounds seem to burn a while, but split em up and look how much wood is actually in one of those rounds. It always surpsies folks how many split pieces can come out of one big round.
It's all wood, and it's all the same btu, moisture content of it is most important and splitting allows for better drying in most cases

Gases like smaller pieces, I split so I can easier pick it up

Thanks for the input. I currently use 24" long logs and my box will take a 32" log. I split the trunk and larger parts of the tree but do not split off the limbs and such. I do kind of keep it light as my wife would have to go load the stove on the rare event I have a gout flair up and I don't want her lifting a tree trunk to load in the stove. Alos my door is only about 14"x18" so big round logs want fit anyway. I have been playing with the load and have used more whole logs on the bottom and split on the top of the load for over night. I've also found if I cut my blower off at night before I go to bed my water temp is stable and use the natureal draft on the front door of my stove. The stack temp stays about 400 degrees and I still have wood and 175/180 degree water in the morning. I use the blower during the day as I can add a few sticks of wood if needed. I found the blower does not have a low end cut off so it my water is at 185 when the blower cuts on and there is not enough fuel in the firebox it will just keep blowing air into the box which cools the firebox and then the water. Maybe I'm wrong but since I turned it off at night we have had hot water for showers and the house is a comfortable 73 degrees and it was 22 lastnight here.

We split everything that is over 8 inches thick and we cut everything at 25 inches long. That is the lenght of the splitter. I like putting in big pieces so get longer burn times and less wood in at one time.

I think it's really a lot about opinion for regular stoves/boilers. All of these responses are good and logical. Large pieces will not burn as hot, but last longer,.... or do they really?? It's funny when you think about it. A less hot fire will cause a longer recovery time. Hotter fire will reduce the recovery time for a shorter burn cycle. And of course split pieces do dry faster, so less wasted btu's drying the wood. So the way I see it, 6 of 1, 1/2 dozen of the other, regarding regular style burners. I have a feeling that most of us running gassers would agree that anything over 6" to 8" should be split to burn properly. Just my $0.02 worth.

i tend to agree with downeast (other than i know nothing about gassers) i dont split becasue my non gasser will burn them, i have no idea if they are more or less efficient but not splitting them save me the time and headache of splitting them, there are less pieces for me to handle and if i have to cut a little more or a little less, i don't know so it does not weigh heavy on my mind ;) just toss and go

Me and my father in law bought a dump truck load of well seasoned split wood this year to help
to help make it through the season. It was actually split good enough for an inside stove.
My boiler would burn it up quickly and get to temp but leave nothing. He built a gasser and
has success burning it. I decided to go back to the larger seasoned 24" stuff and split that in half by hand.
I only use the smaller split wood to assist in starting my fires now I feel it's to wasteful for my setup.

WillieG - If you're getting a headache splitting wood, then you're doing it wrong. :)

i'm so used to banging my head against the wall, i thought i might as well try splitting with it too! :bash:

One of my friends has a 6048 CB and he claims he can get a measurable longer burn by keeping as much of his wood toward the door as he possibly can. His thinking is that the heat has to travel farther to the exhaust, and the extra time the heat is traveling allows for more heat transfer time. The fire box depth on the 6048 is 60". He cuts everything at 24" and splits everything over 7 or 8". If I remember right, he thinks that 10 cu.ft. of wood near the door of the stove will do what 12-13 cu.ft. of wood will do if thrown all the way in. I think he's on to something.
Anyone ever look inside one of those 6048's? They will hold 60 cu.ft. of wood! Mine holds about 11 cu. ft. It looks like you could drive a dump truck in his, as opposed to a Chevy Vega in mine!

He he he. Pretty good point Marty, allowing for more heat transfer. In that particular stove and others of similar design in makes perfect sense.

You think the 6048 is huge...Guy down the street from me has the 7260.. The boiler is massive...He heats a few apts in a very old building and other stuff... Burns 50 cord a year..( runs it all yr. long)..Unlimited wood supply he has..I could probably fit 3 of my boilers in.. Its very impressive set up The whole set up is on a farm

I found the same on my 5036, Burn time are the same with 18 to 22 inch logs as they are for the 36 inch logs.You would think that Central boiler would make that clear when selling the boiler.
My dealer that I bought my boiler from was in Colebrook NH. I wont be using him again.I found a great guy in conway NH.

[/quote] My boiler can hold a 42 inch log..I burn a 24 inch long..Burns the same..Same fill up time..If i were to burn 42 inch wood..I would be wasting wood..Ive seen the CB dealer truck In North Conway from time to time.. Another great dealer is located in Dover..

i find the split burns better in mine but after long day is easer to just through it in hole ,untill you catch a finger ouch! hope to start logsplitter build soon set back i broke my torch got most of the parts
