At some point you will no doubt have come across the magnetic stove thermometers which change colour depending upon the temperature. These are placed on stove flue pipes, a minimum of 300 mm above the stove, and are visible from a distance. When you bear in mind that you can feel the heat coming from your stove it does beg the question, what use is a stove thermometer?
Over fueling
It seems bizarre to suggest that you can over fuel your wood-burning stove but you would be surprised to learn how many people fall into this trap. The idea that you can literally plough was much wood into your stove as possible in order to increase the heat output is inefficient at best and a waste of money at worst.
A stove thermometer will alert you to overheating because quite simply your stove is manufactured to create a specific amount of heat kilowatts. You can pile as much wood into the stove as you want but this will not increase the heat output but it will increase the gas escaping up your chimney – increasing the temperature of the flue and potentially damaging the liner. There is also a danger that it could reduce the lifespan of your stove because put simply it is not manufactured to go above a certain kilowatt output.
