An important thing when using wood or briketter as your main heating source, is to always use clean wood. Why is that? Well lets take a look at some different scenarios and see what happens when you don’t use clean firewood.
Using wet wood
There are several problems when you use “wet” wood to heat your home. Wet wood is defined by the wood containing more than 22% water, where normal dry firewood contains less than 18%, just like the stuff you buy from Billig Briketter, or any other of the larger firewood companies.
The first problem with wet wood is that it’s hard to get burning problemer, the fire simple won’t catch on to the wood as easily. This also means that you will have a poor combustion, which means that a lot of the harmful and toxic particles like dioxin, won’t be burned away and at released in our environment with the smoke. Another similar problem is that all wood contain tar and chlorine in some amounts, and these particles will combine with the water fumes from the wood, and stick to the sides of your chimney. When there is a big enough layer of this on your chimney, it is very likely to catch fire at some point, and you will end up with a chimney fire, which sure isn’t something you would want to have. Even through there have been several improvements in technologies that have made our homes more enjoyable to live in, a stove the can use wet wood properly, isn’t one of them as you can see here.
But wait, there are even more problems when using wet wood. As we all know water isn’t something that burns, so if your firewood contains 25% water, it means that 25% of the wood you throw into your stove or fireplace, won’t give you any act. It actually takes some of the heat to convert the water to mist and remove it from the wood, so this means that heat you get from the wood is a lot lower than when you use a drier version. This is why it might be a good idea to use a known brand like Brænde or Briketter, where you can almost always be sure that it’s dry enough to use right away.
If you have just harvested your wood, it’s much to wet to use, so cut it into useful pieces (around 25cm) and leave it out to dry over the summer, then by fall you should have some wood that is perfect for heating your home.
Using impure wood
Another issue that we often see, are people using wood that is left over from various construction tasks, for instance they might have an old wooden garage that has been taken down, and leaving you with a loot of dry wood, that at first glace, seems like something you could easily use in your fireplace or stove. I just have one word for you… Don’t!
The reason for this is that this type of wood often contains dangerous chemicals, like paint or it’s been impregnated to protect it against the water, and make it last longer. These chemicals combines with the smoke from the firewood and are released into our air, where it gets into the rain and falls down and pollutes our plans and animals. So by burning unclean or impure wood, you not only risk damaging your chimney and stove, you also help pollute our environment.
Using clean wood, on the other hand, isn’t bad for our environment, as the amount of CO2 it releases when being burned, is the same as the wood have absorbed while the tree was growing, so you don’t add any additional CO2 to the environment when using wood as your primary fuel.
