What types of stoves are there?

When choosing a stove or fire its output is a determining factor. Many people are unaware that an average living room space only requires 3 to 4 kilowatts (kW) to heat it. This is especially true in today's well-insulated homes and given the fact that many homes already have central heating; the fire is often just used for additional heating.

Yet consumers often go for a too high an output, with the risk that they subsequently use the fire sparingly or can only burn at a low temperature, otherwise it would become too hot in the room. With wood stoves and fires this results in poor combustion, blackened glass and high emissions.

Calculating the output needed to heat the space you have in mind is very easy. The graph shows the outputs indicated in kWs. The space to be heated is indicated in cubic metres (m3). The number of cubic metres is determined by multiplying the length, width and height of the space. You can then read the output you require at the intersection of one of the three lines. Which of these three lines you select depends on the degree to which your home is insulated.
