This fresh air is drawn into the stove through adjustable dampers which are typically located inside the door of the stove. The exhaust gases are then drawn through a chimney and safely removed from your home. Modern wood stoves that do not have catalytic technology rely on secondary combustion for their efficiency. They can build up creosote, however, when they are not used properly. Energy Efficiency Modern woodburner stoves are constructed to maximize efficiency in heating. The combustion process has been designed to burn firewood as efficiently as possible. This means that a larger portion of the fuel is converted to heat, and less goes to waste in the form of smoke or gas that is not burned. The most important thing to consider when choosing a woodburner stove is the heating output, which is measured in BTU per hour. This figure gives an idea of the amount of heat that the stove will produce. It's generally a good indication of its capability to provide a comfortable heat source for your home. When comparing wood stoves, it's also worth looking at the efficiency of combustion as well as heating transfer efficiency. The combustion efficiency is an indicator of the amount of fuel converted into heat. The efficiency of heating transfer is an indication of how your stove converts this heat to warm the air inside your home. Stoves that use a catalytic combustor can attain very high levels of efficiency in combustion because the combustor is able to re-burn some of the gasses that have escaped the initial combustion process. This helps reduce the amount of flammable creosote in the chimney and helps to clean the exhaust gasses. Modern non-catalytical stoves are still highly efficient. However, they tend to burn more hot and perform less well at lower temperatures. It's important to keep in mind th
