Hi folks....I usually burn 4-5 cords yearly. I've been supplementing stick burning w/ some kind of compressed sawdust product for a while now, starting w/ Bio Bricks about 4 yrs ago. My favorite of all is the Envi Block. Last year I bought 1 ton, this year, 2. Luckily I'm only 10 miles down Rt 8 from CT Pellet and I take advantage of the spring sale price. Yes, they are more expensive than (non-seasoned oak) cord wood, but their convenience is worth the extra cost, imo. For example, no dealing w/ a dumped pile of sticks in the driveway, each of which has to be picked up, put on a log carrier, moved to the wood shed out back, picked up from the log carrier, and stacked in the shed. When that's done, the driveway needs to be cleaned up. Then the sticks get loaded onto the carrier again and moved into the house from the shed using the 50 ft. long, snowblower-cleared path during burning season.
Instead of all that work, I watch CT Pellet put the pallets in the garage. Then during burning season I load the log carrier w/ 10 packs and move them only 20' across the already snow-cleared driveway to the house. Much easier!
Also, they stack easily and compactly inside w/ no mess. No sweeping up the crumbs always left by the sticks. And, no spiders! They ARE a bit sawdust-messy when opened, but its not too bad. I place a cookie sheet right in front of the stove that can fit 1 pack of blocks and open the package on it to contain the mess. I burn 3 blocks at a time, 2 bottom N-S and 1 top E-W.
I love how little air they need to burn, and how relatively precisely the temp can be controlled using the air intake on the stove (Englander 13-NC).
While I'm here I'd like to mention another great wood stove product- the Ecofan. This is the 3rd season and I love it! No more ANNOYINGLY loud stove blower. Google it if you're unfamiliar w/ them. Mine is the Airmax 812 model.
Ok, enough blabbering. Stay warm folks.
