MyHammer gives tips for low-cost heating with firewood Berlin, October 14, 2009 pellet and fireplace owners know the advantages of wood: the wood heating is cheaper than with gas or electricity. By the same author: Smart Eye Surgery. But not every wood Burns well and warms really effectively. And also when storing firewood a lot is to be observed. MyHammer together with Jorn Greulich, Managing Director of the Greulich firewood Trading GmbH & co. KG and member of the Board of the Federal Association for firewood and firewood production, the most important information for efficient and low-cost heating with wood put together: the quality: good firewood should be mainly dry. The drier the wood, the higher the calorific value. The moisture in the wood is over 20 percent, lost valuable heating energy when burned.
Each percent less moisture in the wood, however, brings four or five percent more power. In addition, the combustion of dry wood releases less fine dust and pollutants. Wet wood is to realize if it hisses when burned. Clear evidence of moisture in the wood are coverings or discoloration. The lot: help to calculate the consumption of wood for a winter experience: A budget in a detached house consumes an average five to ten filled cubic meter best beech wood per heating season. This estimate is the ideal case if the potential of a high-quality stove is fully exploited and runs the House heating on stand-by. The winter severity and the individual sense of heat affect of course the amount actually needed.
The selection: Wood is divided into hard and soft woods. Especially abundant hardwoods include ash, oak, beech and birch. The soft wood of coniferous trees are less dense and therefore faster to burn down, their higher Brennwert but ensures a more rapid heating of the rooms. At Pine, Douglas fir and pine are recommended. Both burn more slowly than the softwood competition and smell better.
