Coal size

Other than size, what is the diffrence between nut and stove sized coal. Will one burn longer than the other?

Nut size will pack tighter then stove size that makes the fire burn slower. The stove size allows more air flow making the fire hotter and not last as long.

Thank you, I was thinking of it just the opposite way, I will stick with nut

If your stove will allow it, different coal sizing is beneficial to tuning your stove to varying conditions. I'm sure there's a thread here discussing this issue. Maybe check it out in the search bubble.

Hi , I started off with stove size in my baseburner, no complaints about the heat output , but the burn times were shorter than I expected. However I have just bought a tonne of nut , and I reckon I am using 20lb a day less , and burn times have extended by about 5 hrs . So happy .

There ya go. Nice when a plan comes together, aye?
By the way, "beautiful" stove ya gut there. Thanks for posting.

This winter,I am primarily burning pea coal, due to the long range winter forecast for the east cost.
But I also have some nut for the colder weather, and I also have some stove for the sub teens.
I think next year, I will buy my majority of coal in the nut size, and keep a ton or two of pea for the early and late burning seasons, before going to the shoulder wood burning seasons. Always good to have some stove just in case of sub teen's temperatures .

I found that a 50/50 blend of nut and stove size to be perfect for 90% of my usage. The other 10% (or less) of the time I would top the fuel bed with a thick blanket of fines for low and slow burning thru warm daytimes.
