Morsø’s stoves are EN-approved for firing with wood. If the stove is primarily intended for creating a cosy atmosphere, wood is the obvious choice. In the following, the most widely used fuel types are described.

Wood is an economical fuel and at the same time an environmentally friendly energy resource. When firing with wood no more CO2 is emitted relative to the same quantity of wood decomposed in nature.
Even though you have to go to the woods to buy your wood, wood firing is a financially sound choice compared to oil, electricity or gas. Wood firing requires shorter firing intervals than other fuel types, but on the other hand you will experience quicker and more comfortable heating.
Never use driftwood, as it usually has a high salt content, which damages both the stove and the chimney. Impregnated and painted wood and chipboard emit poisonous smoke and fumes, so they should not be used as fuel either.

Briquettes are suitable as supplementary fuel if, for example, you want to fire all night. Wood briquettes are easily lit on a bed of wood embers.

Which types of wood make the best fuel?
Heavy, hard woods such as oak, beech and ash have the highest calorific value. Spruce, which is a light type of wood, has the least calorific value. Approx. 7 cubic metres standing volume of beech or oak wood correspond to 1,000 litres of fuel oil. If you use common spruce or silver fir, you need to calculate your requirements on the basis of 10 or 11 cubic metres standing volume per 1,000 litres of fuel oil.

Is the wood dry enough?
You can check yourself whether the firewood is sufficiently dry by using a Morsø Moisture Meter.
Although you can fire your Morsø stove with almost all kinds of wood, you should not fire with wet wood, or unseasoned wood. Wood ought to be stored under a roof for at least 1 year, and preferably 2 years, with free access to wind. Wood should be chopped as soon as possible after felling if it is to dry quickly. The wood can be used once the moisture content is less than 20%. During the EN test, all stoves are tested with wood with a moisture content of (16 ± 4)%.

Moist wood can cause smoke and airway irritations. You can use industrial wood waste if it has not been impregnated or bleached with, e.g., salt water or acid. However, wood waste has a limited calorific value, as the wood is oven-dried and the moisture content is therefore too low. Oven-dried wood waste quite simply burns too quickly. Driftwood and the like is not suitable as fuel as it may damage the stove and the chimney through rust or corrosion.
