What you need to know about woodburning stoves
Wood as a fuel source
Woodburning stoves are heated with firewood, which must be added manually. Both hardwoods and softwoods are suitable.
The amount of wood to be used depends on the desired heat output, the size of the room and, of course, the quality of firewood used.
If the stove is used regularly, a suitable storage space for the firewood is recommended. As dry logs burn more easily, a dry and well-ventilated storage location is an important requirement. A good spot would be a canopy with plenty of sunlight.
Fresh wood should be stored for about two years before it is used as firewood. Freshly cut wood has a very high water content, after all, and is therefore difficult to burn. Because the wood releases moisture when it is stored, the logs should be loosely arranged, and be placed at a distance to the floor, ceiling and walls.
All the firewood you need for a given day should be brought to the living room on the previous day so that it can be aired.
For the operation of the stove and generation of heat, there must be a regular supply of fresh air to the stove.
- With a non-room sealed stove, air is taken out of the room in which the stove is located.
- With a room sealed stove, air is fed in via a pipe from outside.
An external air supply is recommended especially when home ventilation and extractor hoods are used together with woodburning stoves, in order to avoid problems with low pressure.
Size of the room
As a matter of course, the size of the room plays an important role in deciding which woodburning stove would be most suitable. The greater the space to be heated, the greater the required heat output.
Another important factor is the insulation. Depending on the size and insulation of the house, the same stove can heat a larger room (with good insulation) or a smaller space (with poor insulation).
A woodburning stove emits heat energy produced through convection and radiant heat.
In convection heat, cool air is warmed, then quickly rises to the ceiling of the room. Radiant heat involves the even distribution of heat waves: in contrast to convection heat, they don’t warm the air, but the substances they meet. This radiant heat ensures a consistent and pleasant interior temperature.
The storage capacity is crucial for determining the amount of radiant heat. This is given in kilograms and ensures that the stove stores more heat and emits this when the fire has gone out.
The proportion of radiant heat can be increased by the use of natural stone panels.
