The most important things to consider
How much firewood is used?
There is no single amount of firewood that suits all households. A stove used a couple of evenings a week for recreational burning consumes significantly less than a stove used daily as a supplementary heat source.
Suitable for those who primarily burn for ambiance on cold evenings.
Common when the stove is used as a supplement to the house's other heating.
Firewood consumption becomes significantly higher when the stove is used several hours every day.
If you have burned before, your own historical consumption is almost always the best basis. Count how many bags you use during a normal winter week and multiply by the number of weeks you want firewood for.
40-liter bags
From kilograms of firewood to number of bags
Vedkillen's 40-liter bag of birch firewood weighs approximately 15 kg. If the calculator, for example, shows a need for 300 kg, that corresponds to approximately 20 bags.
This makes it easy to track your own consumption. If you have used 12 bags, you know that it corresponds to approximately 180 kg of firewood.
Dry firewood makes for better burning
Moisture content also matters
Dry firewood provides better conditions for efficient combustion. If the firewood is too damp, some of the energy is used to heat and evaporate the water in the wood.
Therefore, store the firewood in a dry and airy place and protect it from rain and ground moisture.
Frequently asked questions
Questions about firewood consumption
How long does a 40L bag of firewood last?
That depends on how much firewood your fireplace consumes. A bag contains approximately 15 kg of firewood. If the consumption, for example, is 1.5 kg per hour, that theoretically corresponds to approximately 10 hours of total burning.
How many bags of firewood do I need for the winter?
That depends primarily on how often you burn. Use the calculator above to estimate your needs based on your own burning habits.
How much firewood is used in an evening?
If you, for example, burn for three hours with an average consumption of 1.5 kg per hour, approximately 4.5 kg of firewood is used.
Can I order more firewood later?
Yes. If you are unsure of the entire season's needs, you can start with a smaller amount and track how quickly the firewood is used before ordering the next delivery.
