I light mine once in October and almost never have to relight. Once you get used to how they operate it should be easy.
Dry wood is important especially while forming the coal bed. I try to burn well seasoned dry wood. Some of my rounds are large and probably have 25-30% moisture and I split a lot of it (large splits 1-2 years to dry) to get it to dry to 20% moisture. I get better burns, less smoke and more heat from it.
It sounds funny, but I burn mostly elm or good coaling woods in the shoulder season to keep coals; I mix in some box elder or pine on the colder fall days. If I burn straight box elder or pine I need to load more full to keep the coals going which seems to waste more up the stack. I burn the light woods that don't coal either the warmer winter days or very cold days that I am home to feed regularly. Nothing like a subzero weekend to burn box elder all day and oak at night.
The only reason I burn box elder is I always have so much when clearing field tree lines every year and I hate to waste it all. I don't go out of my way for it. It is marginal wood in the outdoor furnace, but I usually burn 2 cords of it a year.
With some experience one figures out when to load the hardwood for long burns, junk wood for short burns or hardwood to keep the coals going.
