Red Stone Eco Bricks (a very fine product in my opinion) are no longer being sold in Tractor Supply Company (TSC) stores in the Northeast according to Eco Brick national sales manager, Brad Smith. TSC replaced Eco Bricks in the Northeast with Eco-Energy Fuel Blocks (a very poor product in my opinion). They smolder (for me) rather than burn (clouding glass door) and create very little heat. Fuel Blocks now sold at TSC are also significantly more expensive to use than the Eco Bricks they replaced. Fuel Blocks are less dense and contain less product per package than the Eco Bricks sold last season. Eco Bricks last season were rated at around 12,000 btu's per pound (may have changed) while Fuel Blocks are rated at only 8,800 btu's per pound. And, Eco Bricks were sold in 25 pound packs last season and Fuel Blocks this season are sold in 21 pound packs. So, even though the price per pack may be the same as last season ($2.99 - $3.49) Fuel Blocks are significantly more expensive to use than the Eco Bricks they replaced. Just saying. Eco Bricks in my opinion burn better and cost less. And.... Shame on TSC for their slippery marketing system.
