How much heat output does my woodburning stove need?

posted Mar 23 2015


Firstly, one of the most important factors to think about when buying a woodburning stove for your home  is the heat output that the stove gives off. If you were not sure which model would be suited for your living room then this article will explain how to work out and calculate the recommended heat output  the stove will require in order to heat your room sufficiently.

You wouldn’t want to buy a stove that doesn’t have the sufficient heat output needed to heat the room, as you would not get that warm and pleasant feeling that you planned on having on those cold and chilly winter nights. Another factor to consider is not choosing a stove that may produce far too much heat than you wanted and you could end up being uncomfortably hot and actually end up not using your beloved stove as much as you would like too.

Having either one of these problems mentioned above, actually defeats the whole point of having a lovely woodburning stove in the first place. It would be a shame to have to deal with these unnecessary issues after spending lots of your hard earned money on a stove that does not really fit its purpose.


To calculate the correct heat output for your room follow the equation below:
Room Width x Room Depth x Height = Z
Divide the answer (Z) of the above calculation by:
12 for a poorly insulated room
15 for an averaged insulated room
18 for a well-insulated room
So for example if you  had a living room which was insulated quite well and measured at:

Room Width: 6 meters

Room Depth: 5 meters

Height: x 2.5 meters

To calculate
6x 5 x 2.5 = 75 cubic meters
75 ÷ 15 = 5KWs

There are also many stove calculators online that can do all the math for you, but this article gives you a better understanding of how it is all worked out. If you have any questions regarding the heat output required for your home then contact us at West Country Fire.
