Used a few splits last week for the first time. My neighbor had done some renovations and given me a bunch of 2x4's that I had been using. The stuff that I hope to use for the season is now on its 3rd season, mixed borderline quality hardwood (maple and holly mostly I think, a few poplar splits left) and I have between 1/2 - 2/3 cord. Last season I only used 2/3 cord total, but I think that was an anomaly, and I'm not going to be stingy with the heat this year in the name of marital bliss. I also bought a pallet of liberty bricks, which I'm splitting between my 2 houses. Lastly, I have 1.25 cord of oak on its second season that I was hoping not to touch. And finished c/s/s another 1-1.25 cord of oak this fall. Thinking that I'll use the liberty bricks mixed with the oldest wood, esp for the overnight burns, and save the oak for next year. BTW, going to post a review on the Liberty Bricks (I had seen mixed reviews, mostly older). So far I think they compare very favorably to Eco Bricks at < 1/2 the cost. You can pick them up wholesale if you drive to the plant in Doswell, VA.
