osburn 2400 burn time help

Nico1986 · Jan 5, 2014

hey there got a Osborn2400 put in this year its a beast love it have a 2500+ sq Ft house and heats it in the 70-75* range fairly easily. I'm getting 4-5 hr burn times right now which is fine during day but would like to get 6-8 hrs at night. when its under 30* out I always have a bed of coals I load a full load on them at night and cut the airflow 50% until it flares up then I put it to lowest setting.hoping that some here have a Osborn and could offer some pointers and how their burn times are. the unit says in paper work that it has 10-12 hr burn times I knew that was probably a long shot but I think6-8 should be reasonable thanks guys and gals I know ur out there

I have the 2000 and still learning....this is what works for me to have a complete burn cycle and have enough coals to start.

I burn mostly red & white oak. 3 logs E/W ( prefer to have round in the rear) 2 large splits on top between the bottom 3 within an inch or so from secondary's.
If they are short, I'll stuff some N/S on a side. Magnetic thermometer ( top left corner) will go up to around 550-600*, then when it's down to ~ 300* is around
5 hours more or less. I can have a nice coal bed after a total of 7 - 9 hours for a restart which is ~200*

What is your definition of burn times? I hope it's not visible flames! Here's what I get and how I achieve it.

I load my stove N/S all the time. I open my bypass (2300 has one...others don't) until my probe thermometer reads about 300-400. I then close my bypass and leave the door cracked 1/4 inch and the primary air open until the stove top temperatures reach about 500 (flu temps are about 600) which is about 5-7 minutes. I then close the door, wait 2 minutes and turn down the primary air until it is about 1/8th open. My secondaries will last about 1 hour and total flames maybe 2-3. 8-9 hours later I will have a nice bed of coals, the stove top will be about 15-200.

These burn times are with hardwood (maple mostly). What kind of wood are you burning?

For example I loaded a few pieces of maple about 2 hours ago. I have a few lazy flames left. The stove top temperature is 490 on the stove top and the flu gases are 300. These coals (lots of red glow) should put off heat for another 3-5 hours. I don't plan on putting any more wood in it tonight. No overnight burn as I want to clean it out tomorrow morning.

How long has your wood been split?

I hope this helps!

@sweedish chef my "burn time" is defined by still have a bed if coals that still give off decent heat. I burn mostly oak that has been seasoned two years some maple and oak that has been seasoned a year. I usually have coals that I can start a fire from 10-15 hours later. the later sometimes have to add some newspaper but never a lighter. do u normally run yours 1/8th closed. what kind of thermometer do u use.
@Bones I'm also learning my unit also only have had it for a month now trying to find the best way to stack it I find when its over 30 outside I stack it 3/4 full first fire of day then add 2-3 logs every 3 or so hours.on the other hand when's it under 30 outside I just stack full loads every 5 hers or so and my house( 2500+ sq Ft )is 72-75 nice and toasty my wife loves it I've had it up to 77 but that's to much for me
