Get a true name of the maple and we caqn then answer the question. If as guessed above, it's box elder, it will burn fine, but you will wish you had about 2x total volume total, or maybe I should say weight of wood.
Once dry all wood gives you the same BTU's per pound. If it's in fact Box Elder it will weigh a lot less than most other woods of the same size.
My guess is that it will be a lot lower density wood,, fast burning, very little coals (it will burn up fast.)
That being said, a ton of it will yield the same amount of heat as a ton of oak, it will just fill up the wood storage rack faster, and require more racks full to get your 25 gal of syrup boiled down.
Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
