Video: 4 Best Techniques to Stack and Store Firewood - Bright Ideas: Episode 4 2023, February

How to heat in a cost and environmentally conscious way.

Freshly cut wood contains a good 50 percent water. Too much to burn effectively. Because the chimney fire would first have to evaporate the moisture in the log before there is any heating. The unpleasant consequences:

- greasy soot forms in the combustion chamber, - annoying and harmful smoke gases arise, - unburned pollutants escape through the chimney, cover it with hard coatings on the inside (disturb the function, are expensive to remove) and sink outside on the garden and terrace, - Heating output and calorific value decrease.

How to heat in a cost and environmentally conscious way

The best time to cut wood is between December and February. Because in winter the moisture from the trunk and branches pulls back into the roots.

• Saw the wood into 30 to 35 cm long pieces, then split into logs immediately before storing - then it dries better.

• Do not burn wood freshly. Depending on the type of wood, store it outdoors for 1 to 3 years in a sunny and airy place or in an airy shed.

• Stack up in a cross stack under a protective roof on a dry surface, about 5 to 10 cm from the floor. This is how air flows between the logs, they dry better and do not become moldy.

• Protect from rain and snow, but do not cover with a plastic tarp or film, better with boards.

If the wood is stacked against a wall: face forward.

If the fuel is dry to the air, it can be brought into an interior. Prerequisite: it is dry and well ventilated.

• Wood with 15 to 20 percent residual moisture has a particularly good calorific value. The stove builder can measure the residual moisture in the firewood using a special device.

• Only burn natural, air-dry wood.

• Waste and wood residues with paint, glue or coating have nothing in the fireplace - this creates substances that damage the chimney, health and the environment: mercury, sulfur oxide, hydrochloric acid, dioxins or heavy metals escape through the chimney.

• Wood burns without leaving much residue. The ash is full of minerals and is well suited as a fertilizer for the garden.

Different types of wood have different heating qualities. Those who buy wood by weight are best off with dry softwood. However, it likes to spark, so it is not suitable for open fireplaces. If you pay by the cubic meter, you better take hardwood, because it is heavier. Oak and beech wood has the highest calorific value by volume. One cubic meter of hardwood - this corresponds to 450 kilograms - contains as much heating energy as 210 liters of heating oil or 365 kg of lignite briquettes.

Firewood that has already been felled and even dried can be obtained from fuel or wood retailers, in the hardware store, from forest owners or from the forestry office. The working group of the German tiled stove industry, AdK, provides a list of sources of supply for firewood, sorted by federal states.
