Yes, you will see many complaints here of too little heat from new burners in the next couple months. BioBricks will help if the wood is not ideal. Try to get the driest wood you can. Ask around to see if anyone is selling kiln dried wood in your area. It will cost a premium, but is worth it for the first year. Also, you can hasten the drying of your wood stack by bringing it indoors for a couple weeks, especially if it's in a heated space and has a fan blowing through it. And when you stack it outdoors, try to orient the wide face of the stacks a right angles to the prevailing wind so that the wind blows through the stacks. Cover the stacks on the tops only.
