When choosing your stove you initially need to look beyond design and features and concentrate on some more important factors.
For you to have the best possible experience, the stove’s heating capacity must match the actual heating requirement. If you select a stove which is too big for your heating needs the stove’s ability will be partly wasted and you will need to reduce the air supply which in turn, will result in poor combustion (i.e soot will accumulate in the stove and chimney).
It is important that the stove is neither too small, nor too big. Combustion will be more efficient (and therefore cleaner) if you fire more in a smaller stove than less in a large stove.
You need to consider the following aspects:
Calculate how many sq. m the stove needs to heat and select the appropriate stove. A quick a simple ‘calculator’ for this formula is:
In most homes you can base your calculations on 1kW to heat 15 sq. m room space.
If the stove is to be used as the primary heating source, i.e. as the most important heating source in the house, you should select a stove which matches the size of your home and give serious consideration to a convector model stove which distributes the heat better.
However, if the stove is to be used as a secondary heating source, e.g. only for heating a designated area consider a smaller output stove.
Convection stoves have an extra side panel which forms a spacing channel between it and the main body of the stove. The combustion heat is led to the air via these channels. Cold air is drawn in at the base of the stove and drawn up between the side plates and finally out at the top as hot air. The hot air rises, and cold air is drawn in at floor level. This generates quicker air circulation in the room.
This type of stove is well-known and has been used for many stove generations and remains popular despite the prevalence of convection stoves. The reason for this is, among other things, that many people still associate stove heat with radiant heat and that this form produces heat more quickly from the stove.
The side plates on radiant stoves consist of a single layer. This means that the stove emits heat quickly. Radiant stoves are ideal in a room with a high ceiling or in buildings with plenty of draughts, or if you’re looking for rapid direct heat from your fireplace.
Remember the firebox (i.e. stove inner) should be lined with a fireproof material as its insulating effect increases the combustion temperature and therefore the output. Vermiculite slabs are ideal as they protect the cast iron, ensuring it lasts longer.
