Calculate the Heat Requirement of your Room
Please measure the room you wish to place a stove in
Please note that this calculation is designed to give you a general guide and should not be taken as the exact output you need. It can change with the number of doors and windows in the room (including patio), and other factors, such as stairs leading off to other rooms or other draft sources and the general insulation of the building. In these cases you may need to look at a stove with a greater output. If you have a well insulated house then you may not need a larger stove and can under estimate your heating requirement.
For those people looking to buy a stove more for the look rather than the heat output should ensure that you do not buy a stove with an output too large for your room. Doing so may cause you to have to run the stove at lower output, resulting in poorer efficiency, possible flue problems including condensation and reduced visual appeal due to smaller flames. You are better to have a stove that has slightly less output than you require so that the stove is working hard all the time, resulting in more flames and cleaner glass.
