Sitting out in the driveway, maybe. But take those pallets apart and stack that thin wood in the same room the stove is in and they will go down to about 5-6% MC within a couple days. Way too dry.
Awesome kindling, but ridiculously inefficient for heating the home IMHO.
I could have all the kiln-dried pallet wood I want for free (delivery included)... remnants of my buddy's pallet making operation. No nails, no disassembly required, just random boards and (mostly) shorts. I pass on the opportunity every year, and he is stuck chipping the stuff up and blowing it into the nearby woods. I prefer to buy cordwood.
Compare that deal with transporting 15 pallets at a time (mostly air) and taking them out of the truck, stacking them up, running a chainsaw down through the stack (hoping you don't hit an errant nail), trying to find a way to neatly stack the loose boards, keeping them dry (rain will get in between the boards in a flat-stacked pile and tends to stay in there and freeze them together), packing the stove correctly, monkeying around with the air, feeding it every hour, then having to deal with a mess of iron that you can't just throw out on the lawn or put in the garden. All in the name of "free wood".
Not for me. Why bother with pallets if you have a truck and a saw already? Plenty of free scrounge wood all over the place. You can carry a half cord stacked neatly in the bed of a full-size pickup. Why run it with mostly air in the bed? Sure, if you are there at work and they are tossing the things out and you don't mind filling the truck for the ride home (hopefully you don't pass by a stack of free rounds sitting by the side of the road), hell yeah... go for it. I'll bet it gets real old after you are done processing 5 or 10 loads.
But if anybody local to Saratoga Springs, NY wants at all those free pallet-making scraps, PM me and I'll be more than glad to refer you to my friend with the pallet shop. :cheese:
