What Size Stove do I need - Stove Size Calculator Computing the heat output that you require is quite easy. This is how you calculate To create a relaxed room temperature of say 20°/25° C (70° F), when the outside temperature is about freezing, you will need about 1kW (kilowatt) of heat for every 14 m³ of volume. This formula with an example will give you a reasonable guide to the heat output you would need from a wood burning stove or indeed a multi fuel stove. To calculate the cubic volume of the room, measure the length by the width by the height (L x W x H) e.g., a room that is in the 6metres Long by 5metres wide and 2metres high, multiply (6 x 5 x 2) =40, now dived 40 by 14 equals to 4.28kW. Therefore you will require a stove that is approximately 4 to 5kW. You can install a stove with slightly greater output and in turn use with less fuel. You may require a slightly larger stove with higher output depending on the number of windows, number of doors and the degree of thermal insulation of the walls and finally how well insulated is the ceiling. I hope this simple method of calculation helps you with selecting the correct size stove that you require for your room.
