Hotter fires cause less creosote buildup in chimneys.There is nothing new about this centuries-old fire- building technique. But it bears repeating for anyone in the habit of making -- and remaking -- a fire.
A top-burn fire promises more heat from less wood. Because it burns hotter, less creosote builds up in the chimney and fewer pollutants are released into the air.
Top-burn fires start with the biggest logs on the bottom and graduate to smaller pieces of kindling, wood shavings and bits of paper at the top.
The method originated in Europe for tile and masonry stoves. It produces a cleaner burn and allows the stove's masonry mass to soak up the heat, releasing it slowly into the living space for many hours from just one firing. It also works in conventional fireplaces and stoves.
Here's how it works:
Start with the biggest logs on the bottom. Dense hardwoods are best. Layer with smaller, softer wood in crisscross fashion up to the smallest pieces of kindling, wood shavings or bits of paper.
Light from the top.
Refueling is not as critical. After logs collapse, add wood as needed. As long as you have a good bed of embers, the firebox will be hot enough to ignite fresh fuel.
This method also solves start-up smoking problems and produces little or no smoke once it gets going.
